[0029] Refer to Figures 1 - 6 , the embodiment of the present utility model provides a burr-free cutting device for absorbable threads, including a wire winding device 1, a cutting mechanism and a moving mechanism. The wire winding device 1 includes a wire winding base 101. A plurality of cutting positions 1012 are provided on the wire winding base 101. A wire placement position 1011 is between adjacent cutting positions 1012. A plurality of wire winding posts 103 are provided at both ends of the wire winding base 101. Medical suture absorbable threads are wound on the wire winding posts 103. The medical suture absorbable threads pass above the wire placement position 1011 and are sequentially wound on the wire winding posts 103 at both ends. A fixed cover 102 is detachably connected to the wire winding base 101. The fixed cover 102 is closely connected to the wire winding base 101. The medical suture absorbable threads are located between the wire winding base 101 and the fixed cover 102. A plurality of cutting openings 1021 are formed on the fixed cover 102.

[0032] The bottom of the winding base 101 is connected to a moving mechanism that drives the winding base 101 to move.

[0033] The laser passes through the cutting opening 1021 to cut the medical absorbable suture on the cutting position 1012, cutting it off. Subsequently, the cut medical absorbable suture is clamped and fixed by the fixed cover 102 and the winding base 101 to prevent it from falling.

[0034] Refer to Figures 1 - 2 , both ends of the winding base 101 are provided with fixing clips 105, and one end of the medical absorbable suture is fixed on the fixing clips 105.

[0035] By fixing both ends of the medical absorbable suture with the fixing clips 105, it can ensure that the medical absorbable suture remains in a taut state.

[0036] Refer to Figure 6 , a fixing pad 1013 for sealing and wrapping the gap between the fixed cover 102 and the winding base 101 is provided on the wire placement position 1011, and the fixing pad 1013 is located between the fixed cover 102 and the winding base 101.

[0037] The fixing pad 1013 fills the gap, and the medical absorbable suture will not fall or scatter due to the lack of force support after being cut, resulting in being shredded by the laser.

[0038] The fixing pad 1013 is made of a soft material.

[0045] Among them, the structural design of the transverse mechanism 4 is similar to that of the moving mechanism.

[0046] A plurality of fixing holes are formed in the fixed cover 102. Bolt nuts are arranged in the fixing holes and are fixedly connected to the wire-winding base 101.

[0047] The working process of the present utility model:

[0048] When the absorbable wire burr-free cutting device of the present utility model is in use, one end of the medical suture absorbable wire is wound around a fixed clamp 105, and then wound along the wire-winding post 103, and wound along the S shape on the wire-winding posts 103 at both ends respectively. Finally, the end is wound around another fixed clamp 105. Then, the fixed cover 102 is covered on the wire-winding base 101 along the limiting block 104. By shaking the handle 303, the threaded rod 302 is driven to rotate and extends inwards through the engagement with the threaded hole 301 to press and fix the fixed cover 102.

[0049] Subsequently, the moving mechanism is started to drive the moving seat 202 to move. Then, the wire-winding base 101 is driven to move horizontally through the telescopic rod. During this process, at an appropriate position, the medical suture absorbable wire is cut by a laser cutting machine. The cut medical suture absorbable wire is fixed by the fixing pad 1013. Then, the fixed cover 102 is opened, and the medical suture absorbable wire on the wire placement position 1011 is collected.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
