[0021] The utility model will be clearly and completely explained in detail in combination with the drawings.

[0022] As Figure 1 and 5As shown in the figure, a surgical cable gun comprises a fixed part 1, a movable part 2, a top column 3, a spring 4 and a clamping mechanism, etc.

[0023] The fixed part is as shown in the figure Figure 2 As shown in the figure, it comprises a first hand-held part 12 and a guide part 11, a first cavity 13 is arranged in the guide part 11, a first guide slot 16 is arranged at the front end of the guide part, the first guide slot 16 is communicated with the first cavity 13, a top column 3 is fixedly connected to the tail end of the guide part through screw thread, the top column 3 extends into the first cavity 13, a spring 4 is sleeved on the top column 3. A first boss 14 is arranged in the middle of the side wall of the first cavity of the guide part, a second boss 15 is arranged at the front part of the side wall of the first cavity of the guide part. The first hand-held part 12 is convenient for holding by hand, the first cavity 13 is used for accommodating the movable part 2, the first boss 14 and the top column 3 are used for providing limiting and movement guiding for the movable part 2. The second boss 15 is used for driving the movement of the clamping mechanism. The first guide slot 16 can accommodate the cable to pass through.

[0024] As shown in the figure Figures 3-4 The movable part 2 comprises a second hand-held part 22 and an embedded part 21, both of which are of integral structure, the embedded part 21 is embedded into the first cavity 13 of the fixed part, the embedded part 21 can move forward and backward in the first cavity by holding the second hand-held part 2. A second guide slot 23 is arranged at the front end of the embedded part 21, the second guide slot 23 is aligned with and communicated with the first guide slot 16, the clamping mechanism can clamp or release the cable passing through the first guide slot and entering the second guide slot. A second cavity 25 is arranged at the tail end of the embedded part 21, the front end of the top column 3 extends into the second cavity 25, the spring 4 is located outside the second cavity, when the embedded part 21 moves in the first cavity 13, the spring 4 can be compressed or elongated, the top column 3 can limit the backward moving distance of the embedded part and can also guide the movement. In order to facilitate the assembly and cooperation of the embedded part 21 and the guide part 11, a first boss 14 is arranged in the middle of the side wall of the first cavity of the guide part 11, two hanging ears are arranged on the first boss, a third cavity 24 is arranged in the middle of the embedded part 21, the third cavity 24 is communicated with the second guide slot 23, the third cavity 24 forms a large slot hole 241 and a small slot hole 242 on the side wall of the embedded part, when assembling, the first boss 14 can pass through the large slot hole 241, then the embedded part is moved so that the hanging ears on the first boss can be clamped on the small slot hole 242, thus forming the sliding clamping of the first boss and the third cavity. The embedded part can slide in the guide part and will not fall off. In order to make the sliding movement of the embedded part more smooth, a plurality of roller holes 27 are arranged on the embedded part close to its upper and lower surfaces, rollers 7 are movably arranged in the roller holes 27, thus when the embedded part moves forward and backward in the first cavity, the rollers can rotate, the frictional resistance is smaller.

[0025] AsFigures 4-5 As shown, the fourth cavity 26 is triangular, and is in communication with the second guide slot 23. The clamping mechanism is arranged in the fourth cavity 26 at the front end of the embedding piece 21, and can clamp or release the cable entering the second guide slot. Specifically, the clamping mechanism comprises a clamping plate 5, a tooth surface 51 is arranged on the upper portion of the clamping plate 5, a rotating shaft 52 is arranged on the lower portion of the clamping plate 5, a torsion spring 6 is sleeved on the rotating shaft 52, one arm of the torsion spring is embedded in the clamping plate, and the other arm of the torsion spring is embedded in the embedding piece. With the rotation of the clamping plate around the rotating shaft, the torsion spring can be compressed or released, and the tooth surface of the clamping plate can enter or leave the second guide slot. The rotation of the clamping plate is realized by the relative movement of the embedding piece relative to the guide portion. A second boss 15 is arranged on the front portion of the first cavity side wall of the guide portion, and in the initial state, the second boss 15 presses the upper portion of the clamping plate 5 to drive the clamping plate to rotate around the rotating shaft, so that the tooth surface of the clamping plate leaves the second guide slot 23, and at this time, the torsion spring is tightened to store energy. When the embedding piece 21 moves backward in the first cavity 13 in the guide portion, the embedding piece 21 gradually moves away from the second boss 15, the second boss 15 gradually leaves the clamping plate 5, and at the same time, the clamping plate 5 rotates under the drive of the torsion spring 6, so that the tooth surface 51 gradually enters the second guide slot 23, and the tooth surface tightens the cable entering the second guide slot.

[0026] The cable tie gun is used in surgery. First, the cable tie is used to cover the bone part that needs to be tightened, then one hand holds the cable tie gun, the palm is close to the first hand holding part of the fixed part, the four fingers hold the second hand holding part of the movable part, the other hand passes the cable tie head through the first guide slot and the second guide slot of the cable tie gun in sequence, then pulls the second hand holding part backward, so that the embedding piece of the movable part moves backward relative to the guide portion of the fixed part, with the movement of the embedding piece, the second boss gradually leaves the clamping plate, the clamping plate rotates under the drive of the torsion spring, and the tooth surface of the clamping plate clamps the cable. After that, the embedding piece continues to move backward, which drives the cable tie to move backward synchronously, so that the cable tie is tightened. When the embedding piece reaches the top column, the maximum stroke is reached, at this time, the second hand holding part is released, the spring pushes the embedding piece forward, so that it returns to the initial position. In the initial position, the second boss drives the clamping plate to rotate, so that the tooth surface leaves the second guide slot and no longer clamps the cable tie, and the initial state is restored, and the tightened cable tie advances. By repeating the above steps, the cable tie can be gradually tightened. When the required tightening is reached, the cable tie gun is removed from the surgical site, and the excess cable tie is cut off by using surgical scissors.
