Abstract

The invention relates to a purse string suture device, and particularly provides a surgical applicator for forming a purse string suture. A surgical applicator is utilized in forming a purse string suture used to, e.g., close internal anal structure or to narrow a passage for performing transanal dissection to create total mesorectal excision. The surgical applicator includes an actuation assemblyand a reload operatively coupled with the actuation assembly. The reload includes a sleeve defining a lumen extending therethrough, a drive rod rotatably supported within the sleeve, a surgical fastener including a coil body portion rotatably supported on the drive rod such that rotation of the drive rod advances the surgical fastener, and a suture extending through the drive rod.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of U.S. Provisional Patent Application No. 62 / 810,980, filed February 27, 2019, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to a surgical device, and more particularly, to a surgical device for forming a purse string suture using a surgical fastener having a helical coil body that engages the suture. Background technique [0004] Purse string suturing devices are known in the art and may comprise a pair of serrated tissue jaws provided with teeth for clamping the tissue to be stapled therebetween. Such devices include a needle channel extending through teeth on each jaw for receiving a needle attached to a suture for passage through tissue. In use, the tissue to be stapled is clamped between the jaws, and a needle is manually passed through the needle channels in both jaws to pass the suture...
