Abstract
A surgical applicator is useful in forming a purse string suture and may be 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 assembly and a reload operatively coupled with the actuation assembly.
Claims20
A surgical applicator for forming a purse string suture, the surgical applicator comprising:
- an actuation assembly;
- and
- a reload operatively coupled with the actuation assembly, the reload including:
- an outer sleeve defining a lumen extending therethrough;
- an elongate core extending through the outer sleeve;
- an inner sleeve movably supported on the elongate core;
- a drive rod operatively coupled with the inner sleeve such that rotation of the drive rod causes axial displacement of the inner sleeve;
- a surgical fastener slidably supported on the elongate core, the inner sleeve configured to engage the surgical fastener to eject the surgical fastener from the reload when the drive rod advances the inner sleeve;
- and
- a suture extending through the lumen of the outer sleeve and the surgical fastener.

A reload for use with a surgical applicator for forming a purse string suture, the reload comprising:
- an outer sleeve defining a lumen extending therethrough;
- an elongate core extending through the outer sleeve;
- an inner sleeve movably supported on the elongate core;
- a drive rod operatively coupled with the inner sleeve such that rotation of the drive rod causes axial displacement of the inner sleeve;
- a plurality of surgical fasteners mounted on the elongate core, the inner sleeve configured to engage a proximal-most surgical fastener such that rotation of the drive rod advances a distal-most surgical fastener out of the reload;
- and
- a suture extending through the lumen of the outer sleeve and the plurality of surgical fasteners.

- a drive rod operatively coupled with the inner sleeve such that rotation of the drive rod causes axial displacement of the inner sleeve;
- first and second surgical fasteners slidably supported on the elongate core, the inner sleeve configured to engage the first surgical fastener such that rotation of the drive rod advances the first and second surgical fasteners;
- and
- a suture extending through the lumen of the outer sleeve and the first and second surgical fasteners.
