Purse string stapler
First Claim
1. A method for applying a purse string suture to tissue comprising:
- providing a surgical stapler having a handle, stapling means and a suture having a portion thereof releasably retained substantially adjacent the handle by a tubular member, the method comprising the steps of;
positioning tissue to be stapled adjacent the stapling means;
applying a biasing force to the handle means;
securing at least one staple from the stapling means to tissue to form the purse string with at least a portion of the suture;
removing the tubular member and suture from the surgical stapler;
removing the surgical stapler from the tissue; and
tightening the suture about the tissue.

Abstract
An improved surgical stapler for applying a suture to a tissue is provided. The surgical stapler includes handles and a stapling assembly for emplacing a suture and staples into tissue as a purse string suture. Retainer structure, for example, a plurality of guides are provided for releasably retaining a portion of the suture substantially adjacent to the handles. The suture may also be releasably retained substantially adjacent to the handles by passing the suture through a tubular member releasably mounted on one of the handles. A clamp may be used to clamp and secure the suture within the tubular member either before or after removal of the tubular member from the handles.

4. A suture retaining member for mounting a suture on an outer surface of a surgical instrument comprising:
-
a tubular member having a longitudinal bore extending therethrough; a resiliently hinged clamp member cooperating with said tubular member for securing a suture at least partially disposed within the tubular member, the clamp member having a resiliently hinged portion for pivoting a first portion of the clamp member to compress the tubular member against a second portion of the clamp member and at least one opening formed within the resiliently hinged portion for passing the tubular member therethrough.

8. A surgical stapler for applying a suture to tissue, the surgical stapler comprising:
-
a first handle having a distal end and a proximal end; a suture at least partially disposed adjacent said first handle; a tubular member disposed substantially adjacent said first handle, at least a portion of said suture being disposed within said tubular member; a clamp associated with the tubular member, said clamp configured and dimensioned to compress said tubular member; and stapling means, disposed adjacent the distal end of said first handle, for applying at least one staple to tissue such that the suture, in combination with said at least one staple, forms a purse string with the tissue. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. In a surgical stapler for applying a suture to tissue, the surgical stapler having at least one handle and means for applying a suture and staples to tissue, the improvement comprising:
-
a compressible tubular member removably mounted to the at least one handle; and a clamp disposed about a portion of the tubular member, the clamp being movable from a first position to a second position, wherein the tubular member is at least partially compressed by the clamp when the clamp is in the second position.
