Embodiment 1

[0033] Embodiment one: if Figure 1-2 As shown, the pusher piece 2 is integrated with the pusher column 4, the screw sleeve 7 is arranged on the inner bottom surface of the ring cutter 3, and the bottom of the front end cavity of the pusher piece 2 is provided with a hook 12 to be connected with the bottom of the ring cutter 3. When the nail push piece 2 is subjected to a forward displacement, it will drive the rotary sleeve 7 and the cutter 3 to move forward, and at the same time, the spiral guide groove 11 of the rotary sleeve 7 cooperates with the spiral guide rail 9 of the anti-expansion tube 6 of the nail barrel function, forcing the swivel 7 to produce rotational motion. Because the rotary sleeve 7 is riveted and fixed with the cutter 3, the cutter 3 rotates together with the rotary sleeve 7. After the binding is completed, the cutter 3 and the rotary sleeve 7 are pulled back in the nail barrel under the action of the barb 12 of the nail pushing piece.

Embodiment 2

[0034] Embodiment two: if Figure 5As shown, the pusher piece 2 and the pusher post 4 are integrated, the screw sleeve 7 is arranged on the outer bottom surface of the annular cutter 3, and the bottom of the front cavity of the pusher piece 2 is provided with a hook 12 and the bottom of the screw sleeve 7 is articulated. When the nail push piece 2 is subjected to a forward displacement, it will drive the rotary sleeve 7 and the cutter 3 to move forward, and at the same time, the spiral guide rail groove 11 of the rotary sleeve cooperates with the spiral guide rail 9 of the anti-expansion tube 6 of the nail barrel , forcing the rotary sleeve 7 to produce rotational motion. Because the rotary sleeve 7 is riveted and fixed with the cutter 3, the cutter 3 rotates together with the rotary sleeve 7. After the binding is completed, the cutter 3 and the rotary sleeve 7 are pulled back in the nail barrel under the action of the barb 12 of the nail pushing piece.

Embodiment 3

[0035] Embodiment three: as Figure 6 As shown, the push nail piece 2 and the push nail post 4 are integrated, the screw sleeve 7 is arranged on the inner bottom surface of the annular cutter, the fixed screw sleeve 13 is fixed on the outer periphery of the stop tube 6, and the outer wall is provided with a spiral guide rail 9, which is fixed on the stop tube 6. On the upper surface of the threaded insert 8 on the pipe 6, a limit fastening nut 10 is arranged. The bottom of the cavity at the front end of the nail push piece 2 is provided with a hook 12 which is hooked with the bottom of the rotary sleeve 7 . When the nail pusher 2 is subjected to a forward displacement, it will drive the rotary sleeve 7 and the cutter 3 to move forward. 7 to generate rotational motion. Because the rotary sleeve 7 is fixed by riveting with the cutter 3, the cutter rotates together with the rotary sleeve 7. After the binding is completed, the cutter 3 and the rotary sleeve 7 are pulled back in...

Abstract

The present invention relates to a rotary cutter head of binding apparatus for surgical operation. It includes the following several portions: nail chamber, nail-pushing piece, cutter, nail-pushing column and nail tube, it also includes rotating component. The cutter feeding device composed of the described nail chamber, nail-pushing piece, cutter, nail-pushing column, nail tube and rotating component is a rotary feeding device. Said invention also provides the concrete connection mode of all the above-mentioned portions, and also provides the working principle of said rotary cutter head of binding apparatus and its operation method.

Description

technical field [0001] The invention relates to a cutter head of a surgical stapler, in particular to a rotary cutter head of a surgical stapler. technical background [0002] The suturing of surgical operation wound generally adopts means such as manual needle and thread suture, gluing, zipper, stapler, and wherein stapler is as the wound suturing tool of surgical operation, and more and more are adopted by surgical operation, prior art When the knife head of the surgical stapler is feeding and binding the wound surface, the circular cutter is fed in a straight line. Not only does the surgeon need to exert considerable force to complete the cutting, but it is also easy to cause the excess tissue on the wound surface to be cut uncleanly. , causing bodily harm to the recipient. For this reason, most foreign countries have made a lot of improvements on the anvil, such as the ring-shaped anvil that can be cut off, or adding a stage to the anvil; . However, in actual applicat...
