When taking the thread, the plurality of winding rollers can be rotated and adjusted relative to the storage box, and the overall practicality and dust pollution prevention performance are high.

[0004] In actual operation, most suture thread winders cannot fix the suture after it is taken out. After being released, the suture thread winders will automatically rewind, causing the suture head to be retracted inside, making it inconvenient to take it out again.

[0005] It can be seen that the above-mentioned problems existing in the prior art need to be improved urgently. Utility Model Content

[0006] In view of the above problems existing in the prior art, one aspect of the present invention is to provide a non-absorbable surgical suture winder to solve the problems that after a large amount of sutures are taken out, the excess part cannot be recovered, or the ends of the sutures are all retracted into the winder, making it inconvenient to take them out again.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a non-absorbable surgical suture winder, including a winder assembly, the outer wall of the winder assembly is provided with a through groove connected to the interior, the interior of the through groove is provided with a cutting assembly, the cutting assembly includes symmetrically arranged slide grooves, the interior of the slide grooves is symmetrically provided with limiting blocks that can keep sliding to clamp the sutures, and the friction force between the ends of each limiting block and the slide groove is less than the friction force between the limiting block and the suture.

[0009] Preferably, a winding shaft is provided at the center of the winding groove to wind the suture, and torsion springs are sleeved on opposite ends of the winding shaft to drive the winding shaft to maintain reset rotation.

[0010] Preferably, the cutting assembly specifically includes fixing blocks symmetrically arranged on inner walls on opposite sides of the through slot, and a wire outlet slot is formed between the fixing blocks.

[0011] Preferably, the slide grooves are symmetrically arranged on the outer walls on opposite sides of the fixing block, and each of the limiting blocks is slidably inserted into the interior of the slide grooves.

[0012] Preferably, a stopper is fixedly provided at the end of the through slot away from the limiting block, and the stopper is driven to abut against each of the limiting blocks.

[0013] Preferably, a winding shaft capable of maintaining axial rotation is provided at the end of the through slot close to the winding shaft for winding the suture.

[0014] Beneficial effects:

[0015] Compared with the prior art, the non-absorbable surgical suture winder provided by the utility model has the following beneficial effects:

[0016] 1. The friction force is generated by clamping the suture between the limiting blocks, so that after the suture is pulled out, it will be restricted and fixed to prevent the internal torsion spring from rotating and all the sutures will be recovered inside.

[0017] 2. When the suture is pulled out too quickly and caused to be pulled out too much, the limiting block can slide in the slide groove along the direction of the block due to the different friction forces at both ends of the limiting block. When the external suture is cut, the winding shaft is rotated and reset by the torsion spring, so that the limiting block slides and resets, and the protruding part of the suture is retracted into the through groove to avoid being completely exposed to the outside and causing the suture to be contaminated.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-3 As shown, a non-absorbable surgical suture winder includes a winder assembly 1, the outer wall of the winder assembly 1 is provided with a through groove 103 connected to the interior, the interior of the through groove 103 is provided with a cutting assembly 2, the cutting assembly 2 includes symmetrically arranged slide grooves 205, the interior of the slide grooves 205 is symmetrically provided with limiting blocks 204 that can keep sliding to clamp the suture, and the friction force at the end where each limiting block 204 connects with the slide groove 205 is less than the friction force between the limiting block 204 and the suture.

[0026] The main purpose of the non-absorbable surgical suture winder is to clamp the suture between the limiting blocks 204 to generate friction, so that after the suture is pulled out, it will be restricted and fixed to avoid rotation through the internal torsion spring 105, and all the sutures can be recovered inside; when the suture is pulled out too quickly and causes the suture to be pulled out too much, due to the different friction forces at both ends of the limiting block 204, the limiting block 204 can slide in the slide groove 205 along the direction of the block 206. When the external suture is cut, the torsion spring 105 is used to rotate and reset the winding shaft 104, so that the limiting block 204 slides and resets, and the protruding part of the suture is retracted into the through groove 103 to avoid being completely exposed to the outside and causing the suture to be contaminated.

[0027] In the technical solution provided by this utility, Figure 1 , Figure 2 and Figure 3It can be seen that the wire winding assembly 1 includes a wire winding shell 101, and a wire winding groove 102 is opened inside the wire winding shell 101 for placing sutures, and a through groove 103 is configured to drive the wire winding groove 102 to maintain communication with the outside world, so that the suture can be pulled out from the through groove 103 for cutting and use.

[0028] Furthermore, a winding shaft 104 is provided in the center of the winding groove 102 for winding the suture, and torsion springs 105 are provided at the opposite ends of the winding shaft 104 to keep the winding shaft 104 rotating when the winding is not pulled outward, so as to reel in the winding.

[0029] Furthermore, the cutting assembly 2 specifically includes fixing blocks 202 symmetrically arranged on the inner walls of two opposite sides of the through slot 103 , and a wire outlet slot 203 is formed between the fixing blocks 202 , so that the suture can be pulled out or retracted from the wire outlet slot 203 .

[0030] Furthermore, the slide grooves 205 are symmetrically arranged on the outer walls on both sides of the fixed block 202, and each limiting block 204 is slidably inserted into the interior of the slide grooves 205. When the suture is pulled out, the friction between the limiting blocks 204 can drive the limiting blocks 204 to move in the direction of the stop block 206, thereby abutting against the stop block 206. When the suture is not pulled and there is no external pulling force, the internal torsion spring 105 can drive the winding shaft 104 to rotate, so that the suture can move toward the winding shaft 104, and then the friction force can be used to reset the limiting blocks 204, so that the suture protruding from the outside can be recovered to a certain length, thereby preventing the suture from being exposed to the outside for a long time.

[0031] Furthermore, a stopper 206 is fixedly provided at the end of the through slot 103 away from the limiting block 204, and the stopper 206 is driven to abut against each limiting block 204. When the suture is pulled outward with great force, the limiting block 204 can be driven to move toward the stopper 206 through friction. When the limiting block 204 is abutted by the stopper 206, when force is continuously applied and more of the suture is exposed to the outside, after the cutting is completed, the limiting block 204 and the suture will be reset by the rotation of the winding shaft 104, reducing the length of the suture exposed to the outside.

[0032] Furthermore, a winding shaft 201 capable of maintaining axial rotation is provided at the end of the through slot 103 close to the winding shaft 104 to wind the suture, thereby fixing the suture.

[0033] Working principle: When the suture is needed, the protruding end portion of the suture is first manually pulled outward, so that the suture moves outward. When the suture continues to move outward, friction is generated between the limiting blocks 204. After the pulling stops, the friction and the rotation force of the winding shaft 104 driven by the torsion spring 105 are balanced, thereby fixing the suture to prevent it from being completely stored in the through slot 103.

[0034] When a strong external pull is applied, the limiting block 204 can be driven to move toward the stop block 206, thereby abutting against the stop block 206. When the suture is not pulled and there is no external pulling force, the internal torsion spring 105 can drive the winding shaft 104 to rotate, so that the suture can move toward the winding shaft 104, and then the limiting block 204 can be reset through friction, and the suture protruding from the outside can be recovered to a certain length, thereby preventing the suture from being exposed to the outside for a long time.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
