Definitions
- BACKGROUND Surgeons have employed retractors formed by plates to retract tissue and provide access to a surgical site. These retractors are manually inserted by shifting aside the blood vessels, the nerves and the soft tissues by means of their end portions that are positioned adjacent to the spine. The retractors may be completed by pins which have ends inserted in the spine. The retractors can slide along these pins. Another technique teaches connecting the retractors about a frame so as to maintain them in the desired position and clear the operating area between the retractors.
- Prior devices are not fully convenient to use in spinal surgery, in particular for positioning and maintaining retractors in a desired angular orientation relative to the operating space, in providing and maintaining an operating space in a posterior lateral approach, or for maintaining distraction of adjacent vertebrae.
- these prior systems are not fully compatible with spinal stabilization procedures both in the disc space and exteriorly of the disc space. Further, the design of such systems may require tissue retraction and exposure beyond that which may be desirable to minimize trauma to the patient as a result of the surgical procedure.
- Surgical instrumentation systems are provided that particularly, but not exclusively, relate to instrumentation for retracting and shifting aside soft tissues and vessels and also for maintaining distraction of bony structures for the purpose of spinal surgery.
- distractor maintenance mechanisms are pivo tally adjustable relative to the bony structure to which each is engaged to reduce the invasiveness of the procedure and facilitate instrument placement at the operative site through the operative approach formed by the surgical instrumentation system.
- the surgical instrumentation system is adapted for a posterior lateral approach to the spine. It is further contemplated that the surgical instrumentation system has application in other approaches to the spine, either in the posterior-lateral configuration or in an alternative configuration.
- a surgical instrumentation system for providing access to the patient's spine includes a frame and at least one retractor attached to a frame.
- First and second distractor mechanisms are engageable to respective ones of first and second anchors engaged to adjacent vertebrae.
- the distractor mechanisms are pivotal relative to the vertebra to which each is mounted, and can be coupled to the frame to provide a rigid construct between the anchor and the frame to maintain distraction of the adjacent vertebrae.
- a surgical instrumentation system to provide access to the patient's spine includes a frame and a pair of retractors attached to the frame.
- the frame includes a first portion lying in a first plane and a second portion lying in a second plane, the second plane forming an angle with the first plane.
- a medial retractor is attached to the first portion and positionable in an incision adjacent the midline of the spinal column.
- a lateral retractor is attached to the second portion of the frame and positioned in the incision along a posterior lateral approach to the disc space.
- surgical instrumentation to provide access to a patient's spine includes a frame and a number of distractor mechanisms attached to the frame.

- a second distractor mechanism is coupled at its distal end to a second anchor that is engaged to bony structure.
- the first and second anchors allow the first and second distractor mechanisms to be pivoted relative to the vertebrae.
- a surgical instrumentation system includes a frame and first and second distractor mechanisms mounted to anchors engaged to respective ones of first and second vertebrae. Adjustment mechanisms are provided to attach the first and second distractor mechanisms to the frame.

- the surgical instrumentation system 10 illustrated in the figures is adapted to enable a surgeon to effect retraction and shifting aside of soft tissues, muscles, and vessels so as to clear an operating area on the spine while simultaneously maintaining a distraction of adjacent bony portions, such as adjacent vertebrae, of the spinal column.
- Surgical instrumentation system 10 provides an operative approach to the spine for a subsequent surgical intervention such as, for example, to installing spinal prostheses or stabilization systems in a disc space between adjacent vertebrae or exteriorly between vertebrae.
- surgical instrumentation system 10 provides a posterior lateral operative approach in order to, for example, provide access to the disc space for distraction, removal of disc material and bone material, and insertion of spinal implants.
- Surgical instrumentation system 10 also has application in other approaches to the spinal column to provide access to one or more spinal disc spaces or bony structures of the vertebrae.
- Surgical instrumentation system 10 is shown in one operative orientation relative to a spinal column segment S in Figs. 1-6.
- the spinal column segment S includes vertebrae VI, V2 with disc space Dl therebetween; vertebrae V2, V3 with disc space D2 therebetween; vertebrae V3, V4 with disc space D3 therebetween; and vertebrae V4, V5 with disc space D4 therebetween.
- Spinal column segment S can comprise the lumbar region of the spine; however, it is contemplated that surgical instrumentation system includes applications in other regions of the spine, including the thoracic, cervical and sacral regions.
- Surgical instrumentation system 10 is further shown positioned relative to spinal column segment S to provide access to disc space D3 between vertebrae V3, V4, which can correspond to the L3 and L4 vertebrae.
- Surgical instrumentation system 10 can also be positioned to provide access to one or more disc spaces, to disc spaces between other vertebrae of the spine, and in operative orientations other than a posterior-lateral approach.
- Surgical instrumentation system 10 comprises a frame 20 having at least one of two retractors 120 and 220 and a pair of distractor mechanisms 320 releasably attachable thereto.
- Each retractor 120 and 220 includes a blade portion 122 and 221, respectively, for shifting aside soft tissues and blood vessels.
- Distractor mechanisms 320 are mounted to respective vertebrae of spinal column segment S, and may include a retractor portion 332 adapted to contact and retract adjacent tissue.
- retractor 120 In its illustrated operative position relative to the patient for a posterior lateral approach, retractor 120 is positioned medially adjacent the midline or posterior elements of the spinal column segment S, and retractor 220 is positioned laterally or postero-laterally relative to the spinal column segment S.
- retractor 220 is not provided, but rather a single medial retractor 120 is provided and attached to frame 20.
- surgical instrumentation system 10 includes a pair of distraction mechanisms 320 secured to respective ones of the vertebrae V3, V4.
- Distraction mechanisms 320 can be movable attached to frame 20.
- distraction mechanisms 320 can be secured to vertebrae V3, V4 with anchors 100 engaged to respective ones of vertebrae V3, V4.
- anchors 100 are multi-axial screws engaged in the pedicles of the vertebrae V3, V4.
- anchors 100 can be engaged to other portions of vertebrae V3, V4, such as the facets, the anterior portion of the vertebral body, or any posterior elements of the vertebrae.
- 100 can be engaged bi-cortically or uni-cortically to bony elements, or to soft tissue elements.
- frame 20 In the operative position illustrated in Figs. 1-6, frame 20 includes a lateral member 21, a caudal member 23, a medial member 25, and a cephalad member 27. At least one recess 22, 24, 26, 28 is formed in each of the members 21 , 23, 25, 27 to accommodate attachment of a clamping device 40 thereto, as discussed further below.
- Each retractor 120, 220 and distractor mechanism 320 is attached to frame 20 by a respective one of the clamping mechanisms 40 and adjustment mechanisms 70, as discussed further below.
- Members 21, 23, 25, 27 can be integrally formed with one another to provide frame 20 in the form of a ring which completely encircles an opening
- frame 20 includes lateral member 21 that lies in plane PI and medial member 25 that lies in plane P2.
- Plane P2 forms angle A with plane PI .
- Angle A allows the members 21, 25 of frame 20 to follow the patient anatomy, and also allows optimal positioning of retractors 120, 220 on the frame and relative to the patient to provide a posterior lateral access path to the spinal disc space.
- angle A is about 30 degrees.
- Caudal and cephalad members 23, 27 are parallel and extend between lateral and medial members 21, 25 and provide a transition between planes PI and P2.
- Other embodiments contemplate angle A ranging from 0 degrees to 90 degrees.
- cephalad member 27 and caudal member 23 include at least a portion lying in plane P2, allowing attachment of distraction mechanisms 320 to frame 20 in the same plane as medial retractor 120.
- distraction mechanisms 320 When attached to frame 20 and anchors 100, distraction mechanisms 320 can maintain a distraction provided between vertebrae V3 and V4 to restore disc space D3 to a desired disc space height. Such distraction can be achieved with a distraction instrument positioned in the disc space prior to securing distraction mechanisms 320 to frame 20. Such distraction can also be achieved by applying distraction forces to anchors 100 either directly, or through extensions coupled to anchors 100 prior to securement of distraction mechanisms 320 to frame 20.
- the laterally positioned retractor 220 can be eliminated, and tissue retraction along the posterior lateral side is maintained by the tissue displacement provided by and between the laterally oriented sides of distraction mechanisms 320.
- Frame 20 can also be provided in a form in which each member thereof lies in the same plane. Other shapes for frame 20 are also contemplated. For example, frame 20 can be circular, rectangular, square, elliptical or U-shaped. In embodiments eliminating retractor 220, frame 20 can be provided with an open side formed by omitting lateral member 21 , for example.
- Frame 20 may further be provided with one or more brackets 32 to enable the surgeon to attach frame 20 to an arm secured to the surgical table to support instrumentation system 10 in its operative position.
- Medial retractor 120 includes an elongated blade portion 122 extending proximally from a distal end portion 124.
- Blade portion 122 can include a relatively flat profile along its medially oriented tissue contacting surface and its opposite laterally oriented surface which extends along the operative approach to the spinal column. However, curved surfaces are also contemplated.
- Distal end portion 124 is curved medially from blade portion 122, and is positionable along or against the posterior bony structures of the vertebrae, such as the spinous processes.
- Blade portion 122 includes a width that retains tissue, and vessels away from the approach formed between the retractors and distractor mechanisms of surgical instrumentation system 10.
- Blade portion 122 is generally linear along its longitudinal axis between distal end portion 124 and proximal end portion 126.
- Proximal end portion 126 is offset from and extends generally parallel to blade portion 122.
- Proximal end portion 126 is offset laterally relative to blade portion 122 to facilitate placement of blade portion 122 and distal end portion 124 more medially relative to the operative approach when proximal end portion 126 is coupled to frame 20.
- Proximal end portion 126 includes flanges 128 for engaging adjustment mechanism 70, as discussed further below.
- Retractor 220 similarly includes flanges 228 at its proximal end for engaging an adjustment mechanism 70.
- Lateral retractor 220 is formed by an elongate blade portion 221 extending along longitudinal axis 225.
- Blade portion 221 includes a lower laterally oriented tissue contacting surface 222 concavely curved along longitudinal axis 225 and positionable against the tissue to be retracted.
- Blade portion 221 of retractor 220 includes an opposite medially oriented support surface 224 convexly curved along longitudinal axis 225.
- Support surface 224 is oriented toward the operative approach formed by surgical instrumentation system 10. As shown in Fig. 3, support surface 224 of retractor 220 includes a concave curvature across its width and transversely to longitudinal axis 225, forming a slight U-shape that can accommodate and support surgical instruments positioned therealong. Retractor 220 further includes a lower distal end portion 226 tapering in width along longitudinal axis 225 toward the distal tip of blade portion 221 to minimize its intrusion into the surrounding tissue. The curvature of blade portion 221 of lateral retractor 220 also positions its distal end away from the access opening formed into the disc space, providing greater tissue retraction in this area and additional room to accommodate placement of surgical instruments, implants and devices between and along the vertebrae.
- Surgical instrumentation system 10 includes distraction mechanisms 320 mountable to respective ones of the cephalad and caudal members 27, 23 of frame 20 and also to respective ones of the anchors 100.
- Distractor mechanisms 320 each include retractor portion 332 mountable to an anchor extension 142 extending from respective ones of the anchors 100.
- retractor portion 332 includes a tissue contacting surface 340 that is convexly curved between the opposite lateral sides 344, 345 of retractor portion 332.
- Retractor portion 332 includes an opposite surface 349, which includes a pair of arms 334, 335 projecting therefrom and extending therealong that form a receptacle 336 therebetween. Arms 334, 335 can each define a concave inner surface and outer ends that project toward one another to provide receptacle
- Retractor portion 332 further includes a proximal end adapted to be pivotally coupled with adjustment mechanism 70, as shown in Figs 9-11.
- this configuration includes flanges 328 projecting from tissue contacting surface 340 in a direction opposite arms 334, 335.
- Each flange 328 includes an arcuate slot 326 extending therethrough and aligned with one another to receive a pin to pivotally couple retractor portion 332 to adjustment mechanism 70.
- Slots 326 define a range of positions along which distractor mechanism 320 can be repositioned relative to the vertebra to which it is coupled.
- An engagement member 324 is positioned between flanges 328, and includes a number of teeth 325 along a convexly curved surface thereof for selective and locking engagement with adjustment mechanism 70, as discussed further below.
- Adjustment mechanisms 70 provide a pivotal coupling arrangement with each of the retractors 120, 220 and distractor mechanisms 320 that facilitates pivotal adjustment of the retractors 120, 220 and disfractor mechanisms 320 in their operative position in the patient. Adjustment mechanism 70 will be described with reference to distractor mechanisms 320, it being understood that retractors 120, 220 may include a similar proximal end configuration with flanges for coupling with the adjustment mechanism 70 extending therefrom. Adjustment mechanism 70 includes an adjustment handle 72 and a shaft assembly
- Shaft assembly 74 extending from adjustment handle 72 toward distractor mechanism 320.
- Shaft assembly 74 extends to a coupling assembly 76 opposite adjustment handle 72.

- Inner shaft 85 includes an engagement member 87 at a distal portion thereof.
- Engagement member 87 includes a number of teeth 89 at a distal end thereof that interdigitate with teeth 325 of engagement member 324 of retractor portion 332.
- the distal end of engagement member 87 includes a concave profile adapted to receive the convexly curved profile of the adjacent surface of engagement member 324.
- the interdigitating concave-convex surfaces facilitate locking a position of retractor portion 332 after pivoting movement of retractor portion 332, as indicated by arrows 327, when engagement members 87, 324 are disengaged from one another.
- engagement member 87 can then be engaged to engagement member 324 at any one of a number of positions defined by the interdigitating teeth 89, 325.
- the concave-convex mating surface profiles allow all of the teeth to interdigitate in the engaged position at any orientation of distractor mechanism 320, providing rigidity between the adjustment mechanism 70 and the retractor or distractor mechanism to which it is engaged.
- the rigidity of the engagement between adjustment mechanism 70 and distractor mechanism 320 is further enhanced by abutment rollers 92 contacting the ends of the adjacent flanges 328 and with pivot roller 90 restraining flange members 328 therebetween.
- engagement member 87 includes a slot 88 through which pivot roller 90 extends. Pivot roller 90 is free to travel longitudinally along slot 88 as engagement member 87 and inner shaft 85 are longitudinally moved with adjustment handle 72. Accordingly, adjustment handle 72 is operable to selectively release and engage engagement member 87 with engagement member 324.

- distractor mechanism 320 does not include a retractor portion 332, but rather the anchor extension portion of the distractor mechanism contacts and retracts the adjacent tissue.
- Such a modified distractor mechanism can be employed with frame 20 with an opposite distractor mechanism, and a medial retractor 120 alone or in combination with a lateral retractor 220.
- clamping devices 40 In order to secure retractors 120, 220 and distractor mechanisms 320 to frame 20, a number of clamping devices 40 are provided that releasably engage the corresponding adjustment mechanism 70 extending from the retractors 120, 220 and distractor mechanisms 320. As shown in Fig. 6, and in further detail in Fig. 16, clamping device 40 includes a foot portion 50 slidably positioned along the respective member of frame 20.
- Foot portion 50 includes first and second arms 51, 55 defining a receptacle therebetween.
- Arm 51 includes a recessed undercut portion 53 shaped to receive an undercut portion 34 of frame 20 to mount foot portion 50 thereto. The interface between foot portion 50 and undercut portion 34 prevents clamping device 40 from pivoting or lifting from frame 20.
- Foot portion 50 is positionable on the corresponding member 21, 23, 25, 27 by placing foot portion 50 on frame 20 at the corresponding recess 22, 24, 26, 28. Foot portion 50, and thus clamping device 40, can be slid along the corresponding frame member 21, 23, 25, 27 to the desired location therealong where the receptacle between arms 51 , 55 is located along the corresponding undercut portion 34.
- clamping device 40 includes a mounting post 44 extending from foot portion 50, and an inner clamping sleeve 42 positioned about mounting post 44.
- Clamping sleeve 42 includes an upper threaded attachment portion 52 and a lower clamping portion 54.
- Lower clamping portion 54 includes a frusto-conically shaped lower support member
- clamping portion 54 can be compressed about mounting post 44 to selectively grip and release mounting post 44 therebetween. Accordingly, clamping sleeve 42 can be axially translated relative to mounting post 44 and clamped at any one of a number of positions therealong to provide elevational adjustment of the respective retractor 120, 220 or distractor mechanism 320 engaged thereto.
- a coupler 48 is positionable about clamping sleeve 42, and is supported on a contact surface 62 of lower support member 56.
- Coupler 48 includes a relief slot 58 formed therein that divides coupler 48 into upper and lower clamping halves 61, 63 joined by an integral hinge.
- An enlarged receptacle 60 is provided along one side of coupling member 48 in communication with relief slot 58 that is sized to receive shaft assembly 74 of adjustment mechanism 70 therethrough.
- a clamping nut 46 is threadingly engaged to attachment portion 52, and movable therealong to contact coupling member 48.
- clamping nut 46 As clamping nut 46 is threaded downwardly, it contacts coupler 48 to flex clamping halves 61, 63 toward one another, gripping shaft assembly 74 therebetween in receptacle 60.
- coupler 48 includes lower contact surface 64 that presses on contact surface 62 to compress clamping portion 54 of clamping sleeve 42 to mounting post 44.
- Receptacle 60 can be configured to capture shaft assembly 74 therein to prevent shaft assembly 74 from slipping laterally therefrom. Accordingly, clamping device 40 allows adjustment mechanism 70 and the retractor 120, 220 or distractor mechanism 320 to be repositioned relative to frame 20.
- retractors 120, 220 can be disengaged from adjustment mechanism 70 and pivoted, moved toward the center of frame 20, and/or moved away from the center of frame 20. Clamping nut 46 can then be re-engaged to secure the re- positioned shaft assembly 74 in receptacle 60. Coupler 48 and clamping sleeve 42 can further be repositioned or translated up and down along the length of mounting post 44 to accommodate re-positioning of retractors 120, 220 and distractor mechanisms 320 in the patient.
- disfractor mechanisms 320 the arrangement between the distractor mechanism and anchor, adjustment mechanism, and clamping device can provide a suitably rigid coupling arrangement to maintain distraction of the adjacent vertebrae when distraction devices are removed from the disc space.
- One technique for using surgical instrumentation system 10 includes the surgeon making an incision in the skin of the patient to provide access to the facet joints of adjacent vertebrae in a posterior lateral approach.
- Refractor 120 can be placed in the incision to assist in exposing and identifying the underlying bony structure.
- Frame 20 can then be placed around retractor 120, and retractor 220 if employed.
- Adjustment mechanisms 70 extending from retractors 120, 220 can be engaged to clamping devices 40 to maintain and provide for adjustment of the retracted condition of the skin and tissue.
- Anchors 100 are engaged to adjacent vertebrae, and anchor extensions 142 are coupled to corresponding ones of the anchors 100 as discussed above.
- Anchors 100 are engaged to bony structure of the vertebrae positioned on each side of the target disc space.
- anchors 100 can be engaged in the pedicles of the adjacent vertebrae.
- the multi-axial heads on anchors 100 allow anchor extensions 142 to be oriented relative to anchors 100 for attachment to the respective portions of frame 20.
- retractor portions 332 are then engaged to anchors 100 by sliding retractor portions 332 along the respective anchor extension 142, and engaging retractor portions 332 to the anchor extensions 142 with coupling members 160.
- the disc space can be distracted with appropriate distraction or spreading instruments.
- disfractor mechanisms 320 can be pivoted relative to the vertebra to which it is mounted.
- Adjustment mechanisms 70 extending from distractor mechanisms 320 can then be secured to frame 20 with clamping devices 40 when suitably positioned and oriented in the incision.
- Adjustment mechanisms 70 are then engaged to the respective clamping devices 40 to maintain the distracted disc space condition and refracted tissue condition.
- Retractors 120, 220 and distractor mechanisms 320 can be adjusted in the desired angular and elevational orientation by means of the adjustment mechanisms 70 and clamping devices 40. The positioning of retractors 120, 220 and distractor mechanisms 320 may be facilitated by the use of push members, handles or the like.
- the retractors 120, 220 and distractor mechanisms 320 can be made of a material which permits effecting a radiographic monitoring during the operation, i.e. a material which is radio-transparent or radio-translucid. It is also contemplated that this material be selected, for example, from the following group: aluminum, titanium, stainless steel, carbon composites, and plastics.
