Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a coracoid wire passer. Background Art

[0002] The traditional method for treating acromioclavicular joint dislocation is to use a clavicular hook plate. However, due to the complication of shoulder abduction impingement that easily occurs after the operation, in recent years, a method of using a loop plate under arthroscopic shoulder surgery to treat acromioclavicular joint dislocation has been developed, which avoids the complication of shoulder abduction impingement. Usually, the loop plate is implanted through a minimally invasive surgery under arthroscope, and the coracoid process is fixed through the loop plate. However, the treatment of acromioclavicular joint dislocation with a loop plate under arthroscopic shoulder surgery requires the operator to master arthroscopic shoulder surgery proficiently, with a relatively high technical difficulty, and the use of the loop plate cannot be carried out in hospitals without arthroscopic equipment. Currently, many secondary and tertiary hospitals do not have arthroscopic shoulder surgery technology, resulting in the inability to carry out the treatment of acromioclavicular joint dislocation with a loop plate, increasing the difficulty of treating acromioclavicular joint dislocation.

[0003] In the existing treatment of acromioclavicular joint dislocation, the use of a loop plate is complex in operation and relatively high in technical difficulty. This solution aims to solve this technical problem. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a coracoid wire passer. Through the wire passing tube composed of a hollow tube one and a hollow tube two, the traction wire can easily pass through the coracoid process, thus facilitating the traction of the loop plate by the traction wire, reducing the operation difficulty of the loop plate, and making the treatment of acromioclavicular joint dislocation convenient and fast.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows: A coracoid wire passer, including an operating forceps, further including a wire passing tube connected to the operating forceps. The operating forceps includes two mutually hinged forceps rods one and forceps rods two. The wire passing tube includes a hollow tube one with its side connected to the forceps rod one and a hollow tube two with its side connected to the forceps rod two. One end of the hollow tube one is detachably communicated with one end of the hollow tube two. The other ends of the hollow tube one and the hollow tube two are both free ends. The hollow tube one and the hollow tube two form a receiving sleeve for receiving the coracoid process. A steel wire is sequentially passed through the hollow tube one and the hollow tube two, and a traction hole for fixing the traction wire is provided at one end of the steel wire.

[0006] A groove is annularly provided on the inner side of one end of the hollow tube one, and a boss is annularly provided on the outer side of one end of the hollow tube two. The boss is detachably embedded in the groove.

[0007] The other end of the hollow tube one is arranged on the side of the forceps rod one away from the forceps rod two, and the other end of the hollow tube two is arranged on the side of the forceps rod two away from the forceps rod one.

[0008] An arc-shaped support is provided on the side of the first clamping rod. A number of ratchet teeth are arranged in an array on one side of the arc-shaped support. A convex block is provided on one side of the second clamping rod. A retaining platform corresponding to the ratchet teeth is provided on the convex block, and the retaining platform is detachably clamped with the ratchet teeth.

[0009] A handle one is provided at the end of the first clamping rod, and a handle two is provided at the end of the second clamping rod.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] (1) Through the wire passing tube composed of the first hollow tube and the second hollow tube, the traction wire can easily pass through the coracoid process, thus facilitating the traction of the tape-loop steel plate by the traction wire, reducing the operation difficulty of the tape-loop steel plate, and making the treatment of acromioclavicular joint dislocation convenient and fast;

[0012] (2) Through the combination of the ratchet teeth on the arc-shaped support and the retaining platform on the convex block, the combination of the first hollow tube and the second hollow tube is made more firm, avoiding the separation of the first hollow tube and the second hollow tube, so that the steel wire can pass through smoothly, and further improving the traction efficiency of the traction wire on the tape-loop steel plate;

[0013] (3) Through the setting of the convex block of the first hollow tube and the groove of the second hollow tube, the docking accuracy of the first hollow tube and the second hollow tube is higher, and the docking is more convenient and fast;

[0020] In order to more clearly illustrate the technical characteristics of this solution, the following will elaborate on this solution through specific implementation modes.

[0021] See Figures 1-4 , a coracoid wire passer, including operating pliers 1, and also including a wire passing tube 2 connected to the operating pliers 1. The operating pliers 1 include a first plier rod 11 and a second plier rod 12 that are hinged to each other. The wire passing tube 2 includes a first hollow tube 21 whose side is connected to the first plier rod 11, and a second hollow tube 22 whose side is connected to the second plier rod 12. One end of the first hollow tube 21 is separably connected to one end of the second hollow tube 22. The other ends of the first hollow tube 21 and the second hollow tube 22 are both free ends. The first hollow tube 21 and the second hollow tube 22 form a receiving sleeve for accommodating the coracoid. A steel wire 4 is sequentially passed through the first hollow tube 21 and the second hollow tube 22. One end of the steel wire 4 is provided with a traction hole for fixing a traction wire.

[0022] An inner side of one end of the first hollow tube 21 is annularly provided with a groove 221, and an outer side of one end of the second hollow tube 22 is annularly provided with a boss 211. The boss 211 is separably embedded in the groove 221.

[0023] The other end of the first hollow tube 21 is arranged on a side of the first plier rod 11 away from the second plier rod 12, and the other end of the second hollow tube 22 is arranged on a side of the second plier rod 12 away from the first plier rod 11.

[0024] An arc support 5 is arranged on a side of the first plier rod 11. A number of ratchet teeth 51 are arranged in an array on one side of the arc support 5. A protruding block 6 is arranged on one side of the second plier rod 12. A stop platform 61 corresponding to the ratchet teeth 51 is arranged on the protruding block 6. The stop platform 61 and the ratchet teeth 51 are separably clamped.

[0025] A first handle 13 is arranged at an end of the first plier rod 11, and a second handle 14 is arranged at an end of the second plier rod 12.

[0026] Specifically, the narrowest part a of the receiving sleeve 3 is not less than 18 mm to facilitate the accommodation of the coracoid. The lengths of both the first hollow tube 21 and the second hollow tube 22 are 60 mm, the outer diameter is 4 mm, and the inner diameter is 3 mm. The length of the coracoid wire passer is 15 cm, and the length of the steel wire 4 is 20 cm, and the diameter is 1 mm.

[0027] The specific working process of the present utility model:

[0028] When in use, the handle 13 and the handle 2 14 are held in the hand. Since the clamp rod 11 and the clamp rod 2 12 are hinged, the fingers exert opposite lateral forces on the handle 13 and the handle 2 14 to separate the ratchet 51 on the arc support 5 from the stop 61 on the protrusion 6. Then, the clamp rod 11 and the clamp rod 2 12 are rotated respectively to separate the hollow tube 1 21 from the hollow tube 2 22. Figure 2 That is, the hollow tube 1 21 and the hollow tube 2 33 are in a separated state, wherein the connection method of the clamp rod 11 and the clamp rod 2 12 is similar to the scissors in the prior art, and the handle 1 13 and the handle 2 14 can be separated by fingers, so that the ratchet 51 on the handle is separated from the stop 61, which will not be described in detail here;

[0029] The hollow tube 1 21 and the hollow tube 22 are inserted from the surgical incision in front of the clavicle and above the coracoid process, and bypass the root of the coracoid process respectively, and then go down along the inner and outer periosteum of the coracoid process respectively. After bypassing the coracoid process, the stopper 61 slides on the ratchet 51 through the rotation of the handle 13 and the handle 2 14, so that the boss 211 of the hollow tube 1 21 and the groove 221 of the hollow tube 22 are connected. At this time, the coracoid process is in the accommodation sleeve 3 formed by the hollow tube 1 21 and the hollow tube 2 22, and the ratchet 51 on the arc support 5 is combined with the stopper 61 on the convex block 6 to lock the clamp rod 11 and the clamp rod 2 12, thereby preventing the separation of the hollow tube 1 21 and the hollow tube 2 22;

[0030] See also Figure 4 , firmly connect the traction line with the steel wire 4, then pass the steel wire 4 through the hollow tube 22 and out of the hollow tube 1 21, and bring out one end of the traction line. At this time, the two ends of the traction line have thread ends at the two ends of the wire tube 2, and then separate the hollow tube 1 21 and the hollow tube 2 22, and take them out from the coracoid process. At this time, the traction line passes under the coracoid process, and then use the traction line to pass the steel plate with a loop from under the coracoid process, and use the steel plate with a loop to connect the coracoid process and the clavicle to achieve the purpose of reducing the acromioclavicular joint.

[0031] The wire passing tube 2 composed of the hollow tube 1 21 and the hollow tube 2 22 allows the traction wire to easily pass through the coracoid process, thereby facilitating the traction of the steel plate with loops by the traction wire, reducing the difficulty of operating the steel plate with loops, and making the treatment of acromioclavicular joint dislocation convenient and quick;

[0032] The ratchet 51 on the arc support 5 and the stop 61 on the protrusion 6 make the combination of the hollow tube 1 21 and the hollow tube 2 22 more firmly, avoiding the separation of the hollow tube 1 21 and the hollow tube 2 22, so that the steel wire 4 passes smoothly, further improving the traction efficiency of the traction line on the steel plate with loops;

[0033] Through the settings of the boss 211 of the hollow tube 1 21 and the groove 221 of the hollow tube 2 22, the docking accuracy between the hollow tube 1 21 and the hollow tube 2 22 is higher, and the docking is more convenient and fast;

[0034] By arranging the other end of the hollow tube 1 21 on the side of the pliers rod 1 11 away from the pliers rod 2 12, and arranging the other end of the hollow tube 2 22 on the side of the pliers rod 2 12 away from the pliers rod 1 11, the interference and occlusion of the handle 1 13 and the handle 2 14 are avoided, making it more convenient and fast for the steel wire 4 to pass through the wire pipe 2.

[0035] The technical features not described in the present utility model can be realized by or adopted from the prior art, and will not be elaborated here. Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present utility model should also fall within the protection scope of the present utility model.
