Definitions
- the present invention relates to electrically operated surgical tools and methods of their use
- a reusable cord must be properly sterilized prior to surgery in an expensive and complex in-house sterilizer. Once sterile, the cord must be carefully transported to the operating room. There the cord becomes partially non-sterile due to its console connection.
- the instrument cord needs to be thoroughly cleaned prior to its next use. This involves cleaning blood and tissue off the cord with powerful solvents and cleaners. These agents attack the cord and limit its useful life. The cord must be handled by trained medical personnel. A disposable power pack would eliminate these extra tasks and their associated costs.
- Saws and high speed handpieces are used for cutting, shaping and in general removing portions ofbone. Drills are used primarily for making holes, which are then used for inserting wires, pins or screws. These two operations are often used in conjunction with one another during bone and tissue repair procedures. Current pencil grip surgical instruments make it difficult to use more than one instrument at a time during a surgical procedure.
- a cordless handpiece is easier for the physician to operate than similar corded handpieces.
- the controls are basic and are controlled with one hand. Equivalent corded handpieces require complex console instructions and commands.
- a further advantage of cordless handpieces is the greater ease of set-up. Equipment set-up is a significant time issue for hospitals. Corded systems have complicated and time-consuming assembly procedures. Multiple connections are involved. A user must be trained at setting up and operating the console system.
- a cordless instrument can be immediately transported to that area. This is true regardless of the 5 surrounding environment. That is not true of a corded unit.
- a surgical instrument cord connected to a non-sterile console, may be considered only partially sterile. This by itself compromises the integrity of a surgical site. A cordless handpiece maintains sterility throughout the entire surgical operation.
- Surgical procedures often involve cuts at more than one position at a surgical site.
- a 0 convenient way to accomplish this is to pass the surgical instrument over the surgical site. With a corded instrument, this would unfortunately result in the cord being passed over, and perhaps falling into, the surgical site. The resulting tissue damage and contamination can have grave consequences.
- a cordless instrument can easily be passed over the surgical site without contamination risks.
- a physician who needs to make s multiple cuts or holes at various surgical locations needs to be in the position that best suited him or her without trailing a bulky, cumbersome partially sterile cord.
- Cordless instruments have heretofore utilized batteries of the rechargeable type. This adds special problems, because the battery must be sterilized before use; and after each use it must be recharged and then sterilized in preparation for the next use. Presently o available batteries do not lend themselves well to this process.
- a method of perforaiing surgery in which bone or hard tissue may be cut, shaped, or drilled by means of a cordless powered surgical instrument, but without the necessity of subsequently recharging a battery or reestablishing its sterile condition.
- a disposable battery pack can be easily connected to a o surgical instrument, both electrically and mechanically, and after a single use may be detached and safely disposed of as non-hazardous waste, into the waste system.
- a method of performing a surgical procedure is disclosed, utilizing a cordless surgical handpiece powered from a sterile battery pack in which the battery chemistry is based upon lithium/manganese dioxide, the battery being in 5 condition for immediate use without further charging or sterilization, and being adapted after a single use to be disposed of into non-hazardous waste.
- a surgical handpiece and disposable battery are provided with mating sets of electrical contacts which can be mechanically and conductively locked together to ensure correct alignment of the parts, as well as stable mechanical support and reliable electrical operation of the handpiece during the surgical 5 procedure.
- a surgical handpiece and a disposable battery each has a defined longitudinal axis with a set of electrical contact elements arranged generally concentric to that axis, and when those parts are aligned on a mutual longitudinal axis the sets of contacts are adapted to become i o lockingly and conductively interengaged in response to rotation of the battery pack relative to the handpiece.
- Still another feature of the invention is that when using a compact surgical handpiece with a brushless DC motor and a manually operated external trigger for activating and controlling the motor operations, a compatible disposable battery may also be used, with 15 interengaging sets of contacts on the handpiece and battery adapted to become lockingly and conductively interengaged upon rotation of the battery pack relative to the handpiece in a manner that rapidly achieves correct alignment of the parts and also ensures stable mechanical attachment and support during the surgical procedure.
- Fig. 1 (a) is a schematic view of a surgical handpiece in accordance with the invention, showing disposal of an associated battery pack into non-hazardous waste after 25 it has been used;
- Fig. 1 (b) is a cross-section view taken on the Line 1(b) ⁇ (1 (b) of Fig. 1 (a), showing that the battery pack when being disposed of still contains batteries;
- Fig. 2 is a perspective view of a sterile battery pack in its plastic container, in accordance with the invention
- 3 o Fig. 3 is an exploded perspective view of the handpiece and battery pack before they are assembled together;
- Fig. 8 is a longitudinal cross-sectional view showing initial alignment of the battery pack to the surgical drill
- Fig. 9 is a cross-sectional view like Fig. 8, but showing the battery pack after its full insertion and its rotation into a locking attachment;
- Fig. 10 is a perspective view of the battery pack showing in detail its forward end
- Fig. 11 is a perspective view of the batteries contained within the battery pack
- Fig. 12 is a side elevation view of the battery pack
- Fig. 13 is a perspective view of a complete instrument showing an alternate form of trigger for handpiece control.
- a surgical handpiece 10 with housing 12 has a rearward or base end 14, an externally mounted trigger 16, and a tool 18 on its forward end.
- a disposable battery pack 20 has a housing 22 and contains internal batteries 24. Arrow 30 indicates the disposal of battery pack into a waste basket 32 after the surgical handpiece has been used in a surgical procedure.
- the surgical handpiece is a compact device containing a brushless DC motor for moving the tool member 18, a manually operated trigger 16 used for activating motor control operations, and an adjustable tool support mechanism for orienting the tool 18 and securing it in place.
- An electronic circuit not specifically shown, controls and regulates the energy supply to the motor, and is operated externally by the trigger 16.
- Trigger 16 may also control the range of speed, the direction of the cutting tool, and cutting tool braking.
- the energy supply for the handpiece is provided by the battery pack 20 which is secured onto the handpiece by means of a rotating movement.
- This detachable DC electric energy supply ensures correct orientation of the electrical contacts in the battery to those for the handpiece, and also signals to the operator by sound, sight, and touch that the battery is correctly secured in place.
- the battery pack 20 is pre-sterilized and packaged for immediate use in a surgical environment.
- Fig. 2 shows a plastic cover 26 which is preferably used to enclose the battery pack prior to its use.
- the battery pack 20 consists of primary batteries 24 which by definition do not require charging before use. These batteries retain their initial charge for long periods of time. The battery pack is discarded after use and may be considered a disposable component of the instrument system.
- the battery pack preferably contains primary batteries 24 whose chemistry is based upon lithium/manganese dioxide, such as the DL 2/3 A manufactured by Duracell, Inc. of Bethel, Connecticut. These batteries possess a high energy density, have a high rate capability over a broad temperature range, and have excellent capacity retention.

These batteries possess a high energy density, have a high rate capability over a broad temperature range, and have excellent capacity retention.
- the handpiece 10 at its rearward or battery receiving end 14 has an alignment post 40 extending therefrom, which defines a longitudinal axis of the handpiece.
- the sterile and disposable battery pack 20 has an attachment end 50 with a central opening 52 therein, the opening 52 also defining a longitudinal axis of the battery pack.
- the battery pack 20 also has a set of electrical contact elements 54 which are concentric to its longitudinal axis.
- the central opening 52 in the disposable battery pack 20 is adapted to insertably receive the alignment post 40 so as to establish a mutual alignment axis of the handpiece 10 and battery pack 20.
- the battery receiving end of the handpiece 10 also has flat end surface surfaces 44a and 44b which are adapted to be engaged by the battery pack.
- the forward or attachment end of the disposable battery pack has a flat end surface 56 adapted for abutting engagement with the end surfaces 44a and 44b while yet allowing relative rotation of the battery pack relative to the handpiece.
- the set of contacts 42a and 42b on the battery receiving end of the handpiece and the set of contacts 54 on the attachment end of the disposable battery pack are mating sets of electrical contact elements, each set being arranged generally concentric to the mutual alignment axis.
- the sets of mating contacts are adapted to then become lockingly and conductively interengaged in response to rotation of the battery pack relative to the handpiece.
- the post 40 is first partially inserted into opening 52 to establish alignment of battery and handpiece. Then with further insertion, the two sets of contacts will assume a position in concentric relation to their common mutual axis of alignment. THE INTERLOCKING PARTS
- Rearward end 14 of the housing of handpiece 12 has an 5 aluminum cover.
- An end plate 60 made of aluminum closes the rearward end of handpiece housing, as best seen in the cross-section views of Figs. 8 and 9. End plate 60 is recessed inwardly from the extreme rearward end of the housing.
- the rearward end of the handpiece also has flanges that are part of and protrude outward from end plate 60 to control the insertion and locking of the battery pack, designated on Fig. 3 by numerals 44a and 44b.
- flanges On the left side as seen in Fig. 3, there is s a wide gap between 44a and 44b.
- the flanges are preferably formed as an integral part of the end plate 60, as shown in Fig. 8.
- a stop pin 65 seen in the upper right portion of Fig. 6 protrudes inwardly behind flange 44b and limits the rotation of the battery contacts relative to the handpiece.
- the front end of battery pack 20 is shown in Figs. 3, 7, 8, 9, and 10. It has a front end 0 plate 70, formed of plastic material, such as ABS plastic; see Fig. 8. End plate 70 also has a projecting ring 72, with flanges 74, 76. As best seen in Fig. 3, flange 74 on the near side of the battery pack will fit into the gap between lower flange 44a and upper flange 44b of the handpiece, which gap is also on the left as seen in Fig. 3.
- flange 76 on far side of battery pack will fit between flanges 44a, 44b on the 5 far or right side of the handpiece as seen in Fig. 3.
- flange 74 is too wide to enter the gap on the right side as seen in Fig. 3. Therefore, battery pack 20 must be engaged with the handpiece in a predetermined relative position.
- Fig. 8 shows alignment of the two parts of apparatus on their mutual longitudinal axis as the post 40 makes its initial entry into the center hole 52 of the battery pack. Further o insertion of the post ensures the coaxial alignment of the two parts.
- battery pack 20 is rotated to the right, as indicated by arrows 80 in Figs. 3, 4, and
- Fig. 5 shows the locked position, also shown in more detail in Fig. 9. Further rotation of the battery pack relative to the handpiece is prevented by the stop pin 65.
- the contact elements 42a and 42b are made as spring members, so that when the contact elements 54 of the battery pack are seated, there is an audible noise to tell the operator that the properly aligned operating position has been reached.
- the apparatus includes means providing a spring-supported snap action so that the sets of mating contacts become lockingly and conductively interengaged in response to rotation of the battery pack relative to the handpiece.
- the battery receiving end of the handpiece, and the attachment end of the battery pack each has a non-circular external cross-sectional configuration.
- the two housings are essentially square with rounded corners.
- the two external configurations are closely similar in both size and shape, and the rotational position of the battery pack when the contacts are locked together is such that the handpiece and the battery pack then provide an essentially continuous external surface. This indicates to the hand of the operator that correct alignment of the contacts has been achieved.
- Orthopedic surgical instruments are widely used in many delicate bone working procedures. These include spinal surgeries, neurosurgeries and other bone sculpting operations. For these surgeries, a small, light weight, well balanced instrument is desired.
- the handpiece needs to have high speed and power, and be sterilizable.
- the ergonomics of a pencil grip cordless instrument is quantifiably better than corded or pistol grip handpieces.
- Pencil grip allows more, fine motor control and easier eye-hand coordination.
- the improved ergonomics of the pencil grip results in less fatigue by the user.
- a cordless handpiece is more mobile than a corded unit. This makes it easier to pass it around the surgical site, from physician to attendant or assistant.
- a cordless system is also not weighed down by a cord.
- the back of corded or pistol grip handpieces can require tugging or lifting of the handpiece cutting tool, which makes cutting more difficult.
- the cord diameter is very thick for a high performance system, which again limits mobility.
- a further disadvantage of a corded instrument is that it is tethered.
- the handpiece can only be operated at a given distance from the console, restricted by the length of the cord.
- the cord also has associated inductance and capacitance properties which can affect the handpiece performance or electrical complexity of the system.
- extra cord is needed for movement about the surgical site with a corded handpiece.
- the extra cord is either coiled by the physician, held by an attendant or attached to a surgical stand. This coiling necessitates extra labor by operating room (OR) personnel, takes up critical surgical site space and limits mobility of other OR personnel.
- cordless, pencil grip instruments The mobility and transport of cordless, pencil grip instruments is of particular advantage when multiple instruments are needed in a procedure. This is often the case where drilling, sawing and wire driving are all needed. These often come in rapid succession and in different sequences. Time is a critical factor for successful surgical outcomes. 0
- Instrument performance is of critical importance in surgical procedures.
- a key 5 electrical factor with corded handpieces is the cord itself.
- the power cord has a given length associated with it and electrical properties of its own.
- the internal impedance of the cord increases electrical losses and reduces power and performance.
- the power is lost as heat and many have other electro-magnetic interference (EMI) problems associated with it.
- EMI electro-magnetic interference
- the length of cord and flexibility needed o usually necessitate the use of three-phase current.
- the cord also has associated inductance and capacitance properties which reduces performance and necessitates more complex electronics in the console. There are also associated EMI problems with this inductance and impedance. These factors exist with both DC and, especially, AC signals. 5
- the electrical properties of the cord are directly proportional to its length and can only be minimized by shortening the cord or making it thicker. A shorter cord reduces mobility. A thicker cord reduces flexibility and increases costs.
- the basic level of emitted EMI from the battery to handpiece connection, in a cordless handpiece, is zero.
- a corded surgical instrument has a direct connection between the patient and wall or line voltage. Power surges from the outlet must be properly controlled before they reach 5 the patient.
- a cordless instrument which operates with lower voltage, less energy, and a limited capacity power supply, poses a much lower electrical threat to the patient.
- the calibration and preventive maintenance costs associated with a corded handpiece console are not a factor with a cordless system. The elimination of the console results in more operating room table space. This valuable space can then be used for important instruments and equipment which need to be close at hand.
- Cord breakage or damage is a prevalent problem and necessitates cord replacement or 5 repair.
- Cord failure may also damage the handpiece and/or console through electrical shorts or otherwise. Even partial failure will directly decrease the performance of the surgical system.
- Cord repair and replacement is expensive, as is system repair and replacement.
- Cord damage may also result in improper system communications and linkage. This may result in increased cord impedance and consequent loss of handpiece performance. Improper signaling may also lead to improper motor operations and result in handpiece o overheating. This may be a hazard to either the user, patient or attending personnel.
- Disposable, primary battery packs offer a higher energy capacity per volume than 5 equivalent rechargeable batteries.
- the batteries are smaller, which is a distinct advantage in cordless surgical handpieces.
- Disposable, primary battery packs offer a higher energy capacity per weight than equivalent rechargeable batteries.
- the batteries are lighter, which is a distinct advantage in cordless surgical handpieces.
- Disposable batteries are inspected at the manufacturer by trained personnel prior to each use. This gives the products a higher reliability per use than equivalent reusable batteries. This is an advantage during critical use situations that often occur in the operating room.
- Disposable, primary batteries may be entered into the normal waste stream.
- Standard 5 rechargeable batteries are considered toxic and must be properly disposed of outside the normal waste stream.
- disposable primary batteries may be transported by air or other standard methods. Some types of rechargeable batteries need special handling conditions and permits to be safely transported. 0 By their very nature disposable primary battery cells have an immediate charge capacity, unlike rechargeable battery cells. Rechargeable batteries need to be charged on specialized and dedicated chargers. This is an expensive and bulky piece of equipment for the medical facility.
- Rechargeable, secondary batteries need to be recharged immediately prior to each use 5 because they lose their electrical charge very quickly.
- Primary batteries retain their charge for very long periods of time, over ten years. This results in lower service and maintenance costs to hospital for disposable batteries.
- Primary batteries have a much lower cost base than equivalent rechargeable batteries. This usually has the advantage of saving money for medical facilities.
- Disposable primary cells generally have a higher voltage, and thus a higher energy potential than rechargeable cells. Furthermore, a higher voltage allows most standard electrical and electromechanical components and motors to operate more efficiently, with fewer components, at a lower cost.
- Disposable, primary batteries retain their charge capacity under more varied conditions, including thermal, humidity and mechanical (e.g. vibration or shock) than equivalent rechargeable battery cells. This increased robustness is an advantage in surgical operations.
- the handpiece 10' has a rather long-handled trigger 16'.
