Title:
LINEAR STAPLING DEVICE WITH VERTICALLY MOVABLE KNIFE
Document Type and Number:
Japanese Patent JP2021023804
Kind Code:
A
Abstract:
To provide a linear stapling device provided with a vertically movable knife.SOLUTION: A surgical stapling device includes a tool assembly having an actuation sled assembly 48 that includes an actuation sled 70 and a knife 72 movably supported on the actuation sled. The tool assembly includes a structure for moving the knife in relation to the actuation sled between extended and retracted positions in response to movement of the actuation sled through a staple cartridge of the tool assembly. Movement of the knife moves a cutting edge 84 of the knife in relation to the actuation sled within a tissue gap defined by the tool assembly to impart a degree of vertical motion to the cutting edge of the knife. This enables the tool assembly to leverage micro-serrations on the cutting edge of the knife to enhance cutting efficiency of the knife.SELECTED DRAWING: Figure 3
