Endoscopic resection instrument.

摘要

A surgical instrument includes a rigid member that has a bend region that angularly offsets a distal region from a proximal region mounted to a first section of a base; a surgical device extending distally from a second section of the base coaxially with the rigid member carries a surgical tool distal of the bend region, and is flexible at least in the bend region to transmit force applied at a proximal end of the surgical device through the bend region to operate the surgical tool; the first base section is rotatable with respect to the second base section, allowing the relative rotational orientation between the surgical tool and the bend region to be changed. <IMAGE>
