Apparatus and method for resectioning gastro-esophageal tissue

摘要

A system for stapling tissue includes a stapling head and a control unit. The stapling head includes an endoscope receiving lumen extending therethrough and first and second jaws movable with respect to one another between a tissue receiving configuration and a tissue stapling configuration. The first jaw includes a staple firing mechanism and the second jaw includes a staple forming surface. The stapling head further includes gross and fine movement mechanisms controlling gross and fine movements, respectively, of one of the first and second jaws relative to the other of the first and second jaws. The control unit includes a first actuator controlling the gross and fine movement mechanisms and a second actuator operating the stapling mechanism.

1. A method for stapling tissue, comprising the steps of:
inserting into a body a tissue resectioning device including a stapling head having a first jaw including a staple firing mechanism and a second jaw including a staple forming surface; drawing a fold of tissue between the first and second jaws; actuating a gross movement mechanism to move the first and second jaws toward a desired tissue stapling configuration compressing the fold between the first and second jaws; actuating a fine movement mechanism in the stapling head to finely adjust a position of the first and second jaws to the desired tissue stapling configuration; and actuating the staple firing mechanism to drive staples through the fold and against the staple forming surface.
