[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The surgical thread fixer is used by extending the suture coil in the wire box from the first wire hole and the second wire hole, and passing it under the cutter and the rubber pressing block. When the suture needs to be clamped and fixed temporarily, the second pressing rod is only pressed downward to push the pressing plate to drive the rubber pressing block downward, so that the rubber pressing block clamps and fixes the suture with the bottom plate below. When the suture needs to be cut after the suture is completely sutured, the first pressing rod is pressed downward to push the cutting plate to drive the cutter, the pressing plate and the rubber pressing block to move downward at the same time. The rubber pressing block that moves downward first contacts the suture to clamp and fix it, and then the cutter cuts the suture. After the suture is cut, a long distance of the suture is still extended between the wire box and the fixing box to prevent the suture head from being rewound around the wire coil and difficult to find.

[0016] 2. The surgical thread fixer drives the rotating chuck to move outward and compresses the clamping spring by pulling the movable roller to one side. When the opening distance between the rotating chuck and the rotating disk is at the maximum value, the suture coil is placed in the center between the two and the movable roller is released. The outer end of the movable roller moves inward under the traction of the clamping spring and pushes the rotating chuck to move inward to assist the rotating disk to clamp and fix the coil between the two. After the coil is fixed, find one end of the suture coil and pull it outward to pass the suture through the first and second grooves so that the suture enters the first and second holes. The device is convenient for installing the suture coil and using it. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: when the surgical thread fixer is used, in the initial state, first, the turntable 103 and the rotating chuck 106 are rotatably connected on both sides of the inner cavity of the wire box 1 with a wire roller groove 102 on the top, and the outer side of the rotating chuck 106 is connected to the movable roller 104 that penetrates the wire box 1, so as to clamp and fix the surgical wire roll, and a transverse groove 2 and a first wire groove 201 are opened on one side of the wire box 1, and a slider 202 with a first wire hole 203 is slidably connected in the transverse groove 2, so as to feed the wire roll in the wire box 1 into the first wire hole 203 to fix the wire feeding direction, and at the same time, a cutting plate 306 and a pressing plate 310 are slidably raised and lowered in the fixed box 301 arranged in front of the wire box 1, and a cutter 307 and a rubber pressing block 311 are respectively connected to the bottom of the cutting plate 306 and the pressing plate 310, so as to clamp, fix and cut the surgical wire;

[0030] When it is necessary to cut or clamp the surgical suture during surgery, the suture coil in the wire box 1 is first extended from the first wire hole 203 and the second wire hole 302 for use, and passes under the cutter 307 and the rubber pressing block 311 during the process. When it is necessary to temporarily clamp and fix the suture, it is only necessary to press the second pressing rod 309 downward to make it push the pressing plate 310 to drive the rubber pressing block 311 to move downward, so that the rubber pressing block 311 clamps and fixes the suture using the bottom plate 304 below. When the suture needs to be cut after the suture is completely sutured, the first pressing rod 305 is pressed downward to push the cutting plate 306 to drive the cutter 307, the pressing plate 310 and the rubber pressing block 311 to move downward at the same time. The downwardly moved rubber pressing block 311 first contacts the suture to clamp and fix it, and then the cutter 307 can cut the suture. After the suture is cut, there is still a long distance extending between the wire box 1 and the fixing box 301 to prevent the suture head from being rewound back on the wire roll and being difficult to find.

[0031] When the suture coil needs to be installed and used, first pull the movable roller 104 to one side to drive the rotating chuck 106 to move outward and compress the clamping spring 105. After the opening distance between the rotating chuck 106 and the rotating disk 103 is maximum, place the suture coil in the center between the two and release the movable roller 104. The outer end of the movable roller 104 moves inward under the traction of the clamping spring 105, and pushes the rotating chuck 106 to move inward to assist the rotating disk 103 to clamp and fix the coil between the two. After the coil is fixed, find one end of the suture coil and pull it outward to pass the suture thread through the first thread groove 201 and the second thread groove 303 to allow the suture thread to enter the first thread hole 203 and the second thread hole 302. The device is convenient for installing the suture coil and using it.
