Abstract

The present invention provides various exemplary methods and apparatus for actuating surgical instruments. In general, surgical devices may include one or more actuation shafts configured to facilitate actuation of the device. In an exemplary embodiment, the device may include four actuation shafts, two actuation shafts to facilitate articulation of the device and one actuation shaft to facilitate the distal end of the device. The opening and closing of the jaws at the head and an actuation shaft are used to facilitate movement of the cutting elements of the device. In an exemplary embodiment, each of the one or more actuation shafts may include a distal elongated member and a proximal elongated member, the proximal elongated member having a The proximal end of the distal end of the elongate member. The proximal elongated member may be rigid and the distal elongated member may be flexible.

Description

technical field [0001] The present disclosure generally relates to methods and apparatus for actuating surgical instruments. Background technique [0002] Minimally invasive surgical techniques such as endoscopy and laparoscopy are often preferred over traditional surgery because there is often less recovery time, pain, and surgery-related complications with minimally invasive surgical techniques . Rather than cutting through a larger portion of the body to gain access to the lumen, the surgeon relies on the body's natural orifice or creates one or more small orifices through which surgical instruments can be inserted to allow the surgeon to visualize and manipulate at the surgical site . [0003] Some minimally invasive procedures may require articulation of the working end of a device inserted into the body to angularly reorient the working end relative to tissue. During such procedures, it is often necessary to reorient the working end such that the jaws at the working...
