Transluminal endoscopic surgery kit

摘要

A transluminal surgery kit and method of using the same. In one embodiment, the kit may include an endoscope, a surgical instrument, and an overtube. The surgical instrument may be an injection needle. The overtube, whose primary function is to provide a substantially sterile pathway for the surgical instrument, may include a tubular member having a proximal end, a distal end and a plurality of longitudinal bores. A film may cover the distal end of the tubular member. One of the bores may be appropriately dimensioned to coaxially receive the distal end of the endoscope, with the proximal end of the endoscope preferably not being inserted into the bore but extending proximally therefrom. A fastener for securing the tubular member to a lumen wall within a patient, together with a tool for inserting the fastener through the lumen wall, may be disposed within another one of the bores.

1. An overtube for an access tube, the overtube comprising a tubular member having a central longitudinal axis, a proximal end, a distal end comprising a planar distal surface extending perpendicular to the central longitudinal axis and radially inward toward the central longitudinal axis, and at least one longitudinally-extending bore, the at least one longitudinally-extending bore being adapted to removably receive a distal end of the access tube, the distal end of the tubular member being adapted to secure to a lumen wall within a patient,
wherein the distal end of the tubular member comprises a substantially planar cover contacting the planar distal surface and covering a distal end of the longitudinally-extending bore, the cover configured to maintain a sterile environment within the longitudinally-extending bore during insertion of the overtube within the patient.
