Abstract

A surgical instrument (20) adapted for applying a plurality of surgical fasteners to body tissue, the surgical instrument comprising: a frame having a proximal end and a distal end, with a handle (21) positioned at the proximal end and an end effector (80) positioned at the distal end; the end effector being shaped and dimensioned for supporting a cartridge housing (121) and an anvil (122), the cartridge housing and anvil structure being relatively movable between a first spaced apart position and a second position in close approximation with one another; a firing mechanism associated with the end effector and the cartridge housing for selective actuation of the fastening elements for treatment of an individual; and a tissue retention feature (124,125) associated with the cartridge housing and anvil, the tissue retention feature maintaining tissue within the end effector during treatment; wherein the cartridge housing includes staple lines defining the longitudinal extent of the staples being applied via the cartridge module, and the longitudinal extent of the staple line is greater than the longitudinal extent of the tissue retention feature. <IMAGE>

Description

Technical field [0001] The invention relates to a surgical fixation and resection device used for pathological diagnosis and treatment in a fixed resection operation. More specifically, the present invention relates to a tissue retaining mechanism used in conjunction with a surgical staple removal device. Background technique [0002] Surgical staplers and resection devices are commonly used in the diagnosis and treatment of pathology through staple resection. Surgical staple cutters provide a mechanism that expands the transluminal exploitation of mechanical suture devices introduced through the anal passage, mouth, stomach, and connecting passages. Although surgical staplers and resection devices are commonly used for rectal pathology, surgical staplers and resection devices can be used in various environments. [0003] Over time, surgical staplers and cutting devices have evolved. These devices generally include a support frame, a base connected to the support frame, and a nai...
