Patent ID: 7766929

Claim:
A surgical operating apparatus comprising: a sheath including a distal end portion and a proximal end portion; a shaft-shaped probe body inserted through the sheath and including a distal end portion and a proximal end portion, and in which ultrasonic vibration is adopted to be transmitted; a probe distal end portion provided at the distal end portion of the probe body; a jaw rotatably supported on the distal end portion of the sheath and configured to be engaged with the probe distal end portion; a first tubular member including a tubular body wherein the tubular body is fitted on the proximal end portion of the sheath, extends rearward, and includes an elongated slit, and the slit is provided in an outer peripheral wall portion of the tubular body and extends in an axial direction of the sheath; a second tubular member inserted into a rear end portion of the first tubular member slidably in the axial direction of the sheath; a tubular driving member inserted through the sheath slidably in the axial direction of the sheath, and configured to rotate the jaw by sliding movement thereof; and a coupling member including a projection body and an engaging portion wherein the projection body projects outward from the driving member and is passed through the second tubular member to form a coupling body in which the driving member and the second tubular member are coupled to each other, and the engaging portion is engaged in the slit of the first tubular member to couple the coupling body to the first tubular member such that the coupling body is slidable as one body, relative to the first tubular member, along the slit in the axial direction of the sheath.
