When the thread hooking operation is performed, the spindle driving rod 224-2 in the driving shaft 22-2 moves downwards axially, the window 22-21 of the driving shaft 22-2 moves synchronously to the position of entering the shifter 24, the shifting block 242 is driven by the shifting block spring 243 to stop the shifting block 242 from being blocked into the shifting groove 224-22 along the window 22-21, so that the spindle driving rod 224-2 is limited, the spindle driving rod 224-2 moves upwards relative to the driving shaft 22-2, along with the downward movement of the driving shaft 22-2, until the driving inclined surface 2422 of the shifting block 242 abuts against the upper end surface of the window 22-21, the shifting block 242 is forced to move out of the shifting groove 224-22 until the window 22-21 is withdrawn, the reliable thread withdrawing opening of the pressing line end 2241 of the spindle body 224-1 is reached, after the hooking needle 22 is punctured into position, the shifting block 242 is blocked into the pushing step groove 224-21 under the action of the shifting block spring, the spindle driving rod 224-2 is limited under the retention of the shifting block 242, the spindle driving rod 224-2 moves downwards relative to the driving rod 224-2 along with the driving shaft 22-2, so that the spindle driving rod 224-2 abuts against the upper end surface of the driving shaft 22-21, and the thread withdrawing end of the shifting block 242 is kept to be more opposite to the pressing line opening 224, and the upper end of the driving rod 224-2 abuts against the pressing line end of the driving rod 2. preferably, when the crochet hook 22 is located at the initial position of the puncturing operation, the stop shifting end 2421 of the shifting block 242 is correspondingly blocked into the shifting groove 224-22, and the driving motor drives the crochet hook to move downwards after moving upwards to exceed the initial position when driving the crochet hook to pull out the needle, so as to realize the operation of loosening the surgical suture by the line pressing mandrel.
In this embodiment, the transmission mechanism includes a driving arm 25, one end of the driving arm 25 is fixed on a driving shaft 22-2, the other end of the driving arm 25 is connected with a driving nut 26, the driving nut 26 is matched with a driving screw 27, the driving screw 27 is positioned and rotatably matched on the crochet hook positioning guide seat 21, a transmission bevel gear 28 is arranged on the driving screw 27, the transmission bevel gear 28 is matched with a driving bevel gear 29, the driving bevel gear 29 is installed on a motor shaft of the driving motor 23, and the driving motor 23 is installed at a position of the crochet hook positioning guide seat 21 close to the gun-shaped handheld handle 11. The driving bevel gear 29 and the transmission bevel gear 28 drive the driving screw 27 to rotate, so that the driving nut 26 is driven to rotate, and the driving shaft 22-2 is driven to axially move, so that the driving motor 23 is arranged at the position of the crochet hook positioning guide seat 21 close to the gun-shaped handheld handle 11, the weight is concentrated on the gun-shaped handheld handle 11, and the puncturing operation of the puncturing needle 12 is more stable and reliable.
The above embodiments are only for illustrating the present invention, and not for limiting the scope of the present invention, and those skilled in the art may make corresponding modifications or variations, such as the transmission mechanism may also use other transmission forms in the prior art, such as worm gears and the like, under the guidance of the spirit of the present invention. All equivalent technical solutions therefore fall within the scope of protection of the present invention.
