Endoscopic stapling device and method
First Claim
1. A surgical instrument comprising:
- an endoscope including an elongate flexible outer tubular member and a biopsy channel extending longitudinally through said tubular member;
an elongate flexible forceps member slidably disposed in said biopsy channel, said forceps member being provided at a distal end with a pair of forceps jaws each formed on an inwardly facing surface with a longitudinally extending groove;
actuating means for manipulating said jaws between and open and closed position; and
a staple having a spring bias tending to force said staple into an opened configuration, said staple being disposed in a closed prefiring configuration between said jaws when said jaws are closed, said staple having legs each disposed in said closed prefiring configuration in a respective one of the grooves, said staple having interlocking means for locking said staple in a closed postfiring configuration in opposition to said spring bias.

Abstract
A surgical instrument comprises an elongate flexible forceps member having a diameter sufficiently small so that the forceps member is slidably insertable into a biopsy channel extending longitudinally through a flexible tubular endscope member, the forceps member being provided at a distal end with a pair of forceps jaws each formed on an inwardly facing surface with a longitudinally extending groove. A staple having a spring bias construction tending to force the staple into an opened configuration is disposed in a closed prefiring configuration between the jaws and has a pair of legs each disposed in the closed prefiring configuration in a respective one of the grooves in the forceps jaws. The provided with locking elements for locking the staple in a closed postfiring configuration.
