Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an electric hook tangent cutter. Background Art

[0002] Suture is to align or reconstruct the channels of tissues and organs that have been incised or traumatized, so as to restore their functions. It is a basic condition for ensuring good healing and also one of the important basic surgical operation techniques. Different tissues and organs need to be sutured in different ways. Suturing can be carried out with a needle holder or directly with a straight needle by hand. In addition, there are also skin staplers, gastrointestinal anastomosis devices, closing devices, etc.

[0003] The traditional suture method is that the surgeon sutures, and the assistant holds the wire scissors to help cut the thread, which requires the cooperation of two surgeons. Another method is that one surgeon performs the suture. For each stitch, the right hand needle holder needs to be put down, the scissors need to be picked up to cut the suture thread, and then the right hand picks up the needle holder again to suture the next stitch. This cycle continues until the incision (wound) is sutured. This method not only has low efficiency but also brings great surgical fatigue to the surgeon. Therefore, we provide an electric hook tangent cutter to solve the above problems. Content of the Utility Model

[0018] III) Beneficial effects:

[0019] Compared with the prior art, the electric hook wire cutter has the following beneficial effects:

[0020] First, through the design of integrating the functions of hooking and cutting the wire into one, doctors can complete the wire cutting action without interrupting the operation, thus significantly improving the suture efficiency during the operation. Through the coordinated use of the sliding block and the return spring, doctors can complete the wire cutting action with only one hand operation, without repeatedly putting down the needle holder and picking up the scissors, greatly reducing the hand fatigue of doctors during the operation and improving the operation experience. Since the operation is more simple and fast, it also helps to reduce the operation time and further reduce the risk to patients.

[0021] Second, in the present invention, the cutting edge of the shear head piece is recessed and the outer pipe fitting is shorter than the inner pipe fitting, which means that when wire cutting is not required, the cutting edge will not be exposed outside, reducing the risk of accidentally scratching the surrounding tissues, thus improving the safety of the operation.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] As Figure 1-8 shown, the present utility model provides a technical solution: an electric hook wire cutter, comprising a handle assembly 1, a shifting block assembly 2, an inner tube assembly 3, an outer tube assembly 4 and a fixing assembly 5.

[0033] The handle assembly 1 includes a handle part 11. A slider groove 13 is formed in the handle part 11. An inner rod seat groove 12 and an outer tube groove 14 are formed in the inner wall of the slider groove 13. The handle part 11 is made of an insulating material. The rear end of the handle part 11 can be opened, and the electrocoagulation connector can be connected to the inner tube assembly 3 from the rear end of the handle part 11, so that the inner tube assembly 3 obtains the electrocoagulation cutting function.

[0034] The slider block assembly 2 includes a sliding block 21. The bottom end of the sliding block 21 is slidably connected in the slider groove 13. An outer tube connection groove 22 is formed in the sliding block 21. A pad groove 23 is formed in the bottom surface of the sliding block 21. A pad block 24 is inserted in the pad groove 23, and the pad block 24 abuts against the inner bottom wall of the slider groove 13. After the pad block 24 is installed inside the pad groove 23, the sliding block 21 can slide smoothly inside the slider groove 13.

[0035] The inner tube assembly 3 includes an inner tube part 31. A hook head 32 is installed at one end of the inner tube part 31. A hook wire groove 33 is formed in the hook head 32. The other end of the inner tube part 31 is arranged inside the handle part 11. When the inner tube part 31 is installed in the fixing assembly 5, a part of it will protrude.

[0036] The outer tube assembly 4 includes an outer tube part 41. The inner tube part 31 is slidably connected inside the outer tube part 41. A cutting head part 45 is arranged at one end of the outer tube part 41. A cutting edge 47 is formed in the cutting head part 45. The hook wire groove 33 is adapted to the cutting edge 47 for cutting the suture. The inner tube part 31 is longer than the outer tube part 41. The other end of the outer tube part 41 penetrates through the outer tube groove 14 and is detachably connected to the outer tube connection groove 22.

[0037] A second locking groove 25 and a stepped anti-slip groove 26 are formed in the sliding block 21. A connection hole 42 is formed in the outer tube part 41. A first bolt is installed in the second locking groove 25, and the outer tube part 41 is installed in the outer tube connection groove 22 through the connection hole 42 and the first bolt. The stepped anti-slip groove 26 can facilitate the pushing of the sliding block 21.

[0038] A cutting head groove 44 is formed in the outer tube part 41. A connection tube 46 is fixedly connected to the cutting head part 45. One end of the connection tube 46 is installed in the cutting head groove 44. A return spring 43 is sleeved on the outer tube part 41. The two ends of the return spring 43 respectively abut against the inner wall of the slider groove 13 and the sliding block 21. The return spring 43 can support the sliding block 21. After the sliding block 21 moves horizontally in the slider groove 13 and the force applied to the sliding block 21 is released, the sliding block 21 can be quickly reset under the action of the return spring 43.

[0039] The fixing component 5 is detachably installed in the inner rod seat groove 12, and one end of the inner pipe fitting 31 is detachably installed in the fixing component 5. The fixing component 5 includes an inner rod seat 51. The inner rod seat 51 is located in the inner rod seat groove 12. An inner rod groove 52 and a fixing nail hole 53 are formed in the inner rod seat 51, and the inner rod groove 52 communicates with the fixing nail hole 53. One end of the inner pipe fitting 31 is inserted into the inner rod groove 52.

[0040] A first locking groove 15 is formed in the handle member 11, and the first locking groove 15 communicates with the inner rod seat groove 12. A second bolt is installed in the first locking groove 15, and the top end of the second bolt is installed in the fixing nail hole 53.

[0041] Working principle: When the sliding block 21 drives the outer pipe fitting 41 to move forward, the return spring 43 will be compressed. The outer pipe fitting 41 is in a fixed state. The cutting head member 45 with a cutting edge 47 at the front end of the outer pipe fitting 41 gradually approaches the wire groove 33 on the wire hooking head 32. After the sliding block 21 is pushed to the limit, the cutting edge 47 on the cutting head member 45 exceeds the wire groove 33 to cut the suture. When the sliding block 21 is released, the compressed return spring 43 is released, and after the sliding block 21 rebounds, the cutting edge 47 will move away from the wire groove 33, reducing the operating pressure and alleviating the fatigue of the user; the cutting edge 47 is recessed, and the outer pipe fitting 41 is also shorter than the inner pipe fitting 31, so that the cutting edge 47 will not scratch other tissues, improving the safety of the operation.
