Description

Medical cable tie gun and tie wrap used therewith

TECHNICAL FIELD The present invention relates to a medical cable tie gun and a tie wrap used therewith.

BACKGROUND OF THE INVENTION At present, reducing the surgical trauma and reducing the pain caused by surgery has always been the highest concept of surgeons. "Micro-invasiveness" is a new and rich and advanced surgical method that is stimulated by the lofty ideals of medicine in today's fast-changing medical development. It can be said that minimally invasive surgery results in minimal trauma to the patient as much as conventional surgical procedures, including medical structures and psychology. It is characterized by the smallest small orifices, with advanced medical equipment to achieve the same therapeutic goals as conventional surgery. Due to the minimal trauma of minimally invasive surgery, the patient suffers less pain, the body's damage is light, and the recovery speed is fast, so it effectively reduces the iatrogenic trauma and complications caused by traditional surgery. Often referred to as "minimally invasive surgery", its essence is to use "cavoscope" for surgery (or laparoscopic surgery), compared with the traditional surgery, it has the characteristics of small trauma, quick recovery, short hospital stay, etc. The principle is the same as that of open surgery, but the traditional surgical approach, separation procedure, ligation and suturing methods, and observation during surgery (from direct macroscopic observation to endoscopic observation) have been changed. However, as a medical concept, minimally invasive medicine includes all kinds of diagnosis and treatment under the guidance of direct image (inner) or indirect image (ultrasound, X-ray, nuclear magnetic, etc.). Technology, which includes not only endoscopic techniques, but also other technical methods with minimally invasive technical characteristics. Due to the special nature of minimally invasive surgery, most of the instruments for minimally invasive surgery can be drilled into the lesions in the body through the small orifices as described above, and operated with the aid of "cavoscope". However, in the current clinical minimally invasive surgery, when a small tissue organ such as a blood vessel is ligated or ligated in the body, a commercially available absorbable wire ligation with a slip knot is usually used.

Confirmation Circles are performed; for thicker tissues (such as gynecological laparoscopic cervical stump after the next hysterectomy), the absorbable line is usually used to perform a live knot, and then various types of pushers are used for intracavitary push to further tighten the knot. According to the traditional surgical point of view, the ligation effect of the slipknot is unreliable, and occult knot loosening may occur; at the same time, even if the thick absorbable wire is used, its diameter is still different from that of the thick tissue stump. Disparity, which also contradicts the principle of "line and tissue diameter" proportional to traditional surgical ligation. At the same time, due to the structural reasons of various types of pusher, the friction of the tying line cannot be avoided when pushing the slip knot, and the rough damage is generated to some extent, even when the knot is tightened, the ligature is directly broken and broken; It is possible to tighten the ligature, and on the other hand, to avoid repeated pulling and wearing, this contradiction may not be solved. Moreover, due to the possibility of ligation of the tissues and organs along the intestines and the omentum during the operation, if the misoperation occurs, the ligation line can only be cut, which is too wasteful and most Importantly, these all affect the convenience of surgery and the safety of the operation. Therefore, it is imperative that a new type of minimally invasive surgery to overcome the above-mentioned drawbacks is to replace the tie-bar gun with a tool such as a knotter. Of course, in other ordinary medical operations and related medical applications, the above problems are also faced. Therefore, an invention of a new ligating device and a tool that overcomes the above drawbacks, such as the invention of a cable tie gun, is imperative.

At the same time, it is often necessary to use a strap or a strap at the medical or electrical or industrial level. For example, in medical laparoscopic laparoscopic intra-abdominal hysterectomy (CISH), the diameter is about 0. 5cm - 2cm of the cervical stump is ligated. At present, the above medical absorbable line is usually used, and the self-made knot is used for ligation, but the following problems are found during the operation: (1) Whether the ligation is firm or not Exactly, often it does not reach the required degree of firmness; (2) The tying line may be broken during the ligation process; (3) The ligature wire that has not been broken in appearance, whether it is worn by the knotter, there is hidden damage, possible Causes problems such as fracture after surgery; (4) Due to the possibility of ligation of the adjacent organs such as the intestine and the omentum during the operation, if the misoperation occurs, simply cut the ligation band (line) Too wasteful and inconvenient to operate. And most importantly, these all affect the ease of surgery and the safety of the operation, even the unwarranted crisis of life.

Of course, the parts that need to be ligated in other medical operations of medicine, especially the tubal ligation, the subserosal uterine fibroids, etc. will encounter similar situations as above, therefore, a new new The invention of a high-security bandage that is widely used in medicine, medical treatment, and in vitro (such as the bandage of newborn umbilical cord ligation) is imperative.

In addition, in view of the medical improvement of the above-mentioned cable ties, the new type of cable ties can be used for reference in an electrician or other industrial use of a lashing tape, which is made of industrial plastics, has a certain length and width, and certainly has certain The strength, however, is the same as the principle applied to the medical field. Although we can use medical or biological materials such as absorbable materials, but like the straps used in industry, the medical application is also Need It must have a certain length and width, and of course also have a certain strength, so that when the actual application and the clinical operation or the medical process are tied, it is necessary to treat the excess cable body, usually shearing, but the cable tie after the cutting The body generally has a relatively sharp cut surface or an incision. In practice, the cut surface or the incision often causes damage to the adjacent tissue in the body, causing serious sequelae, even if it needs to be cut after industrial tying the object to be ligated. There will be a sharp cut or a cut surface. When a precision object appears or the surface is soft and not bumpy, the damage of the item is inevitable. There is no other way, so it is not only inconvenient to operate, but also caused A waste of resources. In summary, an innovative invention that can be applied to minimally invasive surgery such as endoscopic surgery, and which can be applied to other general medical and medical straps, and the like The invention of the tie wrap with the tie gun is imperative.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of the present invention will be described in detail below with reference to the drawings, It is to be understood that the appended drawings are not intended to be As shown in FIG. 1-14, the medical cable tie gun of the present invention is applied to the medical field, and can be loaded with a medical strap and used for tying or other surgical treatment of the body tissue or the organ with a medical strap. The medical cable tie gun comprises a gun body 6 and a T-type trigger structure 7, the gun body 6 includes a gun handle 601, a gun head 602 and a long round barrel 603 located therebetween (of course in practical applications The length of the barrel can be adjusted according to the specific application field. For example, the extended long barrel can be used for endoscopic surgery, as shown in this embodiment, the short barrel is used for other operations such as laparotomy, the gun body The front end of the gun handle 601 is provided with a T-type trigger structure 7, and the T-type trigger structure 7 includes a trigger 702 and a lateral bolt 701, that is, a long round barrel 603 at the upper end of the front end of the gun handle 601 of the gun body 6. The transverse groove 6031 of the transverse bolt 701 of the T-type trigger structure 7 of the T-type trigger structure 7 is disposed therein, and the horizontal groove 6031 is provided with a groove 6032 near the position of the gun handle 601, the groove 6032 and the horizontal direction The grooves 7011 provided on the inner side of the tail portion of the plug 701 are opposed to each other and cooperate to form a receiving space for accommodating a spring (not shown) capable of reciprocating and laterally dragging the trigger structure in the gun body. The front end of the recess 6032 is provided with a "T"-shaped rib 6033. The front end of the recess 7011 of the trigger structure 7 is provided with a transmission chute 7012 that cooperates with the rib 6033. The trigger structure 7 is provided. The transmission chute 7012 can be slidably engaged with the ribs 6033 provided in the long round barrel 603 of the gun body to realize lateral reciprocating drag between the trigger structure 7 and the gun body 6. Of course, in order to increase the stability of the gun body and the trigger structure 7, the length of the transmission chute 7012 and the ribs 6033 can be appropriately lengthened according to the length of the barrel 603, or the stability requirement is satisfied. Under the premise, the lengths of the transmission chute 7012 and the ribs 6033 can be appropriately modified to meet different production and practice needs. Of course, for the power transmission mechanism disposed on the gun body 6, in addition to the above-mentioned utilization groove 6032 and The ribs 6033 are matched with the transmission chute 7012, and may also be a plurality of sleeve hinge structures disposed on the gun body. For example, the existing scissors-type hinges are commonly used in the tools used in many endoscopes and the like, and are provided with a plurality of hinge mechanisms at the barrel and the handle. Of course, the direct The transmission mode has the advantages of low power loss, short delay time, direct and reliable, but the traditional multi-site or single-hinging method still has some practical points due to the long time of operation. In short, all can be from the above transmission structure. Directly equivalent, the transmission mechanism that can be conceived without the need for creative labor is within the scope of the present invention. At the front end of the long round barrel 603, the front end of the horizontal groove 6031 is provided with a card point 6012, and the horizontal pin 701 of the T-type trigger structure 7 is opposite to the card point 6012 of the horizontal groove 6031. The corresponding portion is provided with a scalloped groove 7015. The scalloped edge of the scalloped groove 7015 is provided with a toothed belt, and the scalloped groove 7015 further extends upwardly with a circular hole 7016 extending through the upper surface of the transverse plug 701. The card point 6012 and the sector slot 7015 and the circular hole 7016 together form a receiving structure-cutter operating room that can accommodate the cutter 8 that cuts the strap. The cutter 8 is a movable metal insert or a latch with a small spring (not shown), and includes a first retaining portion 801 and a scalloped slot 7015 and a circular hole that are engaged with the snap point 6012. The first latching portion 801 and the second latching portion 802 are coaxial with each other, and a small spring latching portion is disposed directly below the first latching portion 801 (FIG. Not shown in the figure), the cutter 8 is bounced or lowered with a small spring, and is moved by the coaxial two holding portions as a center of rotation.

The cutter 8 rotates back and forth along the sector edge in the sector slot 7015 with the click point 6012 and the round hole 7016 as the center axis in the lateral reciprocating drag between the trigger structure 7 and the gun body 6 to cut off the loading of the cable tie gun. Medical tying strap (the medical ligature strap loaded into the tying gun will be described in detail below). The cutter 8 is provided with serrations that can be engaged with the positioning teeth on the strap (the triangular teeth 201 of the strap used in the present invention), not only to achieve one-way tightening or loosening, but also to cut off quickly in the later stage. Medical strapping to reduce surgery or medical time, improve the safety of surgery. In detail: It is assumed that the direction of the tip is "front" and the direction of the trigger is "rear". When the trigger 702 is not pulled, the metal insert or the cutter 8 is in the fan shape due to the spring at the trigger 702. The front of the slot 7015, that is, near the tip of the gun, is in a natural horizontal position; when the trigger 702 is pulled, the metal insert 8 moves toward the "rear", and after moving to the fan-shaped slot, there is a space, and the small spring acts to bounce off. At an acute angle, the strap is engaged between the metal insert and the scalloped groove of the toothed belt. Due to the reaction force of the trigger, the more the occlusal force generated by the trigger metal insert 8 and the plastic toothed sector groove is made. When the trigger pulls the cable tie, it will not slip off, so that the cable tie can be reliably tightened; when the cable tie is pulled to the maximum and can not continue to be tightened, further exerting a larger grip force on the trigger, the bite force will further increase, that is, The cable tie can be automatically cut off; the process is only tightened to the maximum at the cable tie It will only happen when the limit is reached. The foremost end of the nozzle head 602, that is, the front end of the horizontal groove 6031 is provided with a "U"-shaped groove 6023, and the cut-off piece 6025 for preventing the trigger structure 7 from moving forward can be installed in the "U"-shaped groove 6023, thereby further ensuring The use process of the cable tie gun and the manual force of the user ensure the safety of the use of the cable tie gun. The middle portion of the T-type trigger structure 7 corresponding to the head 602 is provided with a strap pulling slot 7027 extending transversely through the trigger structure 7, and the middle portion of the blocking piece 6025 is provided with a strap pulling groove. The cable tie is cut off from the slot 6028. Continuing, the T-type trigger structure 7 extends along a long barrel extending into the body of the body, and has an extension portion 7028 for receiving the binding band in cooperation with the T-type trigger structure of the T-type trigger structure. Tie body. In the minimally invasive surgery or endoscopic surgery, when the tissue of the lesion needs to be tied, the medical banding is penetrated into the body through the small hole of the operation, and the active knot and the pre-binding of the diseased tissue are completed in the body. Continuing to place the cable tie gun of the present invention into the body of the body through a long barrel capable of deepening into the body of the body, and inserting the cable body that has been in the pre-bundled state through the cable tie slot. The 6028 is received into the strap pulling slot 7027 of the trigger structure 7; after the above steps are completed, the grip is gripped, and the T-type trigger structure 7 is pulled to realize the lateral reciprocating drag between the trigger structure and the gun body. At the same time, the cutter 8 disposed at the position of the lance is unidirectionally dragged in the direction of the tying strap in the scallop 7015 between the cutter operations; the serration on the cutter 8 and the positioning teeth on the ligature (the present invention) The triangular teeth 201 of the binding tape used can be engaged in one-way tightening without loosening, that is, when the T-type trigger structure 7 is pulled by the grip, the cutter 8 moves up along the sector slot 7015 to the card. At this time, the binding tape at the upper end of the cutter 8 continues to pull the trigger 702, at which time the cable body has been clamped and is unidirectionally moved toward the handle 601 with the T-type trigger structure 7 in the direction of the cut-off piece. Under the action of 6025, the moving strap body can only tighten the knotted knot that is pre-knotted at the same time, and then tie the tissue to be tied tightly. After the trigger 702 is fastened to the maximum extent, relax, at this time, the cutter 8 Moving downward along the sector slot 7015 to release the originally engaged strap, the strap automatically extends toward the extension 7028 within its own elastic limit, and repeats the operation when it is relaxed to the maximum amplitude and the grip trigger 702 is gripped again. Until the ligature has been fully tightened, at this time, the ligature tape at the upper end of the cutter 8 will be repeatedly clamped, and the saw teeth of the cutter 8 and the cutting force of the cutter itself are cut off, that is, After the tightening action of the above steps reaches a sufficient tightening effect, the fixing position of the binding band will always be in the reciprocating cutting state of the cutter until the binding band is cut off, and the ligating operation is ended. Of course, in order to ensure that the strap at the extension portion 7028 and gradually tightening toward the extension portion 7028 is no longer moved in the opposite direction, that is, in the direction of the cut-off piece 6025, it may be disposed in the middle portion of the extension portion 7028 or other suitable position. There is a holding mechanism (not shown), the clamping mechanism tightens the binding band that enters the extending portion 7028, and does not move in the reverse direction, and when the tightened strap is cut off After that, the remaining part of the cable body will be automatically clamped by the holding mechanism and will not fall into the patient, thereby increasing the safety of the operation and greatly reducing the probability of medical accidents. As shown in FIG. 15-18, in order to use the strap for use with the medical cable tie gun of the present invention, it is of course also possible to use other common medical straps, but the strap has a new invention improvement, and the tie gun of the present invention is matched.
