As preferably, described stopping means comprises back-up ring and gear cap, and described back-up ring is connected with the end of pull bar, keeps off the front end that cap is coated at slide bar, when the first resetting means and the second resetting means are in reset mode, keeps off the inner side of cap and the front end of back-up ring offsets.Back-up ring carries out position restriction to gear cap, and structure is simple, easy to use.
As preferably, described first resetting means is big spring, is enclosed within pull bar outside big spring, and one end and the claw beam seat of big spring offset, and the other end offsets with the front end of gear cap.Structure is simple, is convenient to install and use, and production cost is low.
As preferably, described second resetting means is little spring, and one end of little spring and the end of back-up ring offset, and the other end and cavity body inwall offset.Structure is simple, is convenient to install and use, and production cost is low.
As preferably, the described pin that surely clamps is integral type with pull bar, and dynamic to clamp pin be elastic pincers pin.
As preferably, the two ends of described connecting rod respectively claw beam seat are connected with holder female thread.Convenient installation.
As preferably, described claw beam and claw beam seat laser weld.Solid and reliable.
As preferably, described back-up ring and pull bar laser weld, gear cap is threaded with slide bar.While solid and reliable, be convenient to install.
After adopting above structure, compared with prior art, have the following advantages: round end shape of being corrected one's mistakes by pincers pin, claw beam Front-end Design becomes spininess to band protection hernia repair pincers of the present invention, and pull bar rear portion adopts spring to withstand design.In piercing process; pincers pin is subject to resistance rollback in claw beam; punctured by claw beam sharp portion; when after puncture transfixation, under the effect of little spring restoring force, clamp pin automatic spring, round end shape not easily causes tissue injury; after entering intracavity; whole process, pincers pin is positioned at before claw beam sharp portion all the time, plays a protective role.

Detailed description of the invention
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
As Fig. 1-3 shows, the band protection hernia repair pincers that the present embodiment provides, it comprises claw beam 1, and the front end of described claw beam 1 is sharp portion 2, and the end Laser Welding of claw beam 1 is connected to claw beam seat 3; Be provided with pull bar 4 in claw beam 1, the front end of pull bar 4 is provided with determines pincers pin 5 and dynamic pincers pin 6, and the described pin 5 that surely clamps is integral type with pull bar 4, and dynamic pincers pin 6 is elastic pincers pin, and the head surely clamping pin 5 is circular, surely clamps pin 5 and is longer than dynamic pincers pin 6 length; The end thread of described claw beam seat 3 is connected with connecting rod 7, and the end thread of connecting rod 7 is connected with holder 8, and holder 8 inner sleeve has the slide bar 9 slided along pull bar 4, and the front end of slide bar 9 is provided with stopping means; The front end of described stopping means is provided with the first resetting means, and rear end is provided with the second resetting means, and described first resetting means is located in the space between connecting rod 7 and pull bar 4, and the second resetting means is located in the cavity body on slide bar 9; End and connecting rod 7 outer surface of described pull bar 4 are equipped with Ring put around finger for massage of cavity of human body 10; When second resetting means is in reset mode, dynamic pincers pin 5 and surely to clamp pin 6 exposed outside claw beam 1, and claw beam 1 by dynamic pincers pin 6 and surely pincers pin 5 compress.
Described stopping means comprises back-up ring 11 and gear cap 12, the end laser weld of described back-up ring 11 and pull bar 4, the front end that gear cap 12 is coated at slide bar 9 is threaded with slide bar, and when the first resetting means and the second resetting means are in reset mode, the gear inner side of cap 12 and the front end of back-up ring 11 offset.
