[0025] Secondly, there are two fixed blocks 106, which are respectively located on the front and rear sides of the clamp 102. The rotating shaft 107 is arranged between the two fixed blocks 106, and the rotating shaft 107 is movably arranged in the clamp 102. A limit position is arranged on the rotating shaft 107 or the clamp 102 to limit the rotation angle of the clamp 102 outside the rotating shaft 107.

[0026] Again, the rotating rod 108 is movably arranged in the base plate 101, and the rotating block 109 is fixed outside the rotating rod 108 and is arranged on the side of the rotating plate 103 close to the base plate 101, and partially extends out of the base plate 101. By rotating the rotating plate 103 above the base plate 101, the rotating block 109 can be driven to rotate along the axis of the rotating rod 108 in the base plate 101, and then the rotating rod 108 can be driven to rotate along the axis of the rotating rod 108 in the base plate 101.

[0027] At the same time, the first gear 110 is arranged outside the rotating rod 108, the second gear 111 is meshed with the first gear 110, the transmission rod 112 is arranged between the second gear 111 and the movable hook 105, and the first gear 110, the second gear 111 and the transmission rod 112 are all located in the bottom plate 101, the first gear 110 and the second gear 111 are both bevel gears, and the first gear 110 and the second gear 111 are arranged vertically, the first gear 110 and the rotating rod 108 are coaxially arranged, the second gear 111 and the transmission rod 112 are coaxially arranged with the movable hook 105, when the rotating rod 108 rotates along its own axis, the first gear 110 will also rotate along the axis of the rotating rod 108 together with the rotating rod 108, thereby driving the second gear 111 to rotate along its own axis, and then driving the movable hook 105 to rotate along the axis of the second gear 111 through the transmission rod 112.

[0028] In addition, the unwinding rod 113 is movably arranged outside the base plate 101, the limiting ring 114 is detachably connected to the unwinding rod 113 and is located at the end of the unwinding rod 113 away from the base plate 101, the connecting plate 115 is arranged outside the rotating plate 103, the connecting plate 115 has a through hole, and the through hole is located at the center of the connecting plate 115, the screw 116 is detachably connected to the rotating plate 103 and is located on a side of the rotating plate 103 close to the connecting plate 115, the wire clamping ring 117 is arranged outside the rod portion of the screw 116, and the unwinding drum wrapped with suture thread can be placed outside the unwinding rod 113, and the position of the unwinding drum is limited by the limiting ring 114.

[0029] Finally, a return spring 118 is provided between the base plate 101 and the rotating plate 103. There are two return springs 118, and the return springs 118 are located at the front and rear sides outside the clamping plate 102. When the rotating plate 103 is pressed, the return spring 118 will be compressed, and the movable hook 105 will rotate counterclockwise at this time. When the rotating plate 103 is no longer pressed, the compression force on the return spring 118 disappears. Since the return spring 118 has a self-recovery effect, the return spring 118 will drive the rotating plate 103 to move in the direction of restoring to its original position, so that the movable hook 105 will rotate clockwise, realizing the reciprocating rotation of the movable hook 105.

[0030] When using a fascia lata patch suturing device of the present embodiment, the splint 102 is rotated above the base plate 101 along the axis of the rotating shaft 107, so that the distance between the splint 102 and the base plate 101 is continuously increased. When the maximum distance between the splint 102 and the base plate 101 is greater than the thickness of the fascia lata patch after being folded in half, the fascia lata patch is folded in half and placed between the base plate 101 and the splint 102, and the splint 102 is rotated again in the opposite direction along the axis of the rotating shaft 107 above the base plate 101, so that the distance between the splint 102 and the base plate 101 is continuously decreased. At this time, the limit on the rotating shaft 107 or the splint 102 can limit the rotation angle of the splint 102 outside the rotating shaft 107, so that the splint 102 and the base plate 101 can jointly clamp the fascia lata patch after being folded in half.

[0031] After clamping the folded fascia lata patch, the unwinding drum with the suture wrapped around it can be placed outside the unwinding rod 113, and the position of the unwinding drum can be limited by the limiting ring 114. Thereafter, the suture is unwound, passed through the through hole of the connecting plate 115, and clamped by the wire clamping ring 117. At this time, the distance between the wire clamping ring 117 and the rotating plate 103 can be adjusted by adjusting the length of the screw 116 in the rotating plate 103 to prevent the wire clamping ring 117 from clamping the suture too tightly. Then, the suture is passed around the wire clamping ring 117 and then through the threading needle 104 to complete the winding of the suture.

[0032] After the suture is wound, the rotating plate 103 is pressed, so that the rotating block 109 and the threading needle 104 can be driven to rotate along the axis of the rotating rod 108 in the bottom plate 101. At this time, the return spring 118 is compressed, and the threading needle 104 rotates along the axis of the rotating rod 108 in the bottom plate 101. The threading needle 104 can drive the suture to pass through the splint 102 and the folded fascia lata patch and penetrate into the bottom plate 101. 01 along the axis of the rotating rod 108, thereby driving the rotating rod 108 to rotate along the axis of the rotating rod 108 in the bottom plate 101. When the rotating rod 108 rotates along its own axis, the first gear 110 will also rotate along the axis of the rotating rod 108 together with the rotating rod 108, thereby driving the second gear 111 to rotate along its own axis, and then driving the movable hook 105 to rotate along the axis of the second gear 111 through the transmission rod 112. The movable hook 105 hooks the suture thread after the needle 104 is inserted, and then the rotating plate 103 is released, so that the compression force on the reset spring 118 disappears. Since the reset spring 118 has a self-restoring effect, the reset spring 118 drives the rotating plate 103 to move in the direction of restoring to the original position, so that the movable hook 105 rotates clockwise and drives the needle 104 to rotate in the opposite direction in the bottom plate 101, so that the needle 104 and the movable hook 105 can reciprocate. , so that the movable hook 105 can hook and release the suture thread on the needle 104, so as to achieve the suturing of the fascia lata patch. In addition, the suturing device is not only suitable for the suturing of the fascia lata patch, but also suitable for the suturing of other patches and tendons, etc. By adopting the suturing device for suturing, the time required for medical staff to suturing is shortened, the suturing efficiency is improved, and the technical problem that in the existing suturing process of the fascia lata patch, the medical staff needs to spend a long time, thereby reducing the suturing efficiency of the fascia lata patch is solved.
