Abstract:
1. An endoscopic resection apparatus comprising: an elongated body comprising a proximal end and a distal end; a resection frame located proximate the distal end of the elongated body, the resection frame comprising two spaced apart rails and a cross member, wherein the resection frame comprises an extended position and a retracted position, and wherein the two spaced apart rails and the cross member of the resection frame define a resection plane between the rails and the cross member; a cutting instrument located on the cross member between the two spaced apart rails of the resection frame, wherein the cutting instrument is displaced from the distal end of the elongated body when the resection frame is in the extended position, and wherein movement of the resection frame to the retracted position moves the cutting instrument towards the distal end of the elongated body moves the cutting instrument within the resection plane; wherein the cross member comprises either a plurality of staples or a stapling anvil, and wherein the plurality of staples and the stapling anvil are located on opposite sides of the resection opening when the resection frame is in the extended position, and further wherein movement of the resection frame into the retracted position moves the plurality of staples or the stapling anvil on the cross member within the resection plane and forces the plurality of staples into contact with the stapling anvil; and a resection opening defined by the two spaced apart rails and the cutting instrument when the resection frame is in the extended position, wherein the size of the resection opening decreases and wherein tissue extending through the resection opening is severed by the cutting instrument when the resection frame is moved into the retracted position from the extended position.
