ENDOSCOPIC SURGICAL INSTRUMENT WITH DEFLECTABLE AND ROTATABLE DISTAL END

摘要

An endoscopic bioptome having a proximal end and a distal end includes a proximal handle assembly including first and second actuators, a distal end effector assembly having jaws for cutting tissue samples, and a hollow member extending between the handle and the end effector assembly. The hollow member includes a first axial portion extending from the proximal end to a second axial portion at the distal end of the hollow member. The second axial portion is more flexible than the first axial portion. The bioptome further includes a control member connected at the proximal end to the handle assembly and at the distal end to the end effector assembly. Actuation of the first actuator causes the control member to open and close the jaws. The bioptome further includes a deflecting device connected at the proximal end to the second actuator and extending through at least a portion of the hollow member. Actuation of the second actuator causes the deflecting device to axially displace into the second axial portion to deflect the distal end of the hollow member.
