Abstract:
1. A surgical operating apparatus comprising: a sheath having a distal end and a proximal end; a rod-shaped probe main body configured to be inserted into the sheath and having a distal end and a proximal end, and which is configured to transmit ultrasonic vibration; a jaw pivoted to the distal end of the sheath; a probe distal end which is provided at the distal end of the probe main body and meshes with the jaw; and a driving member including a tubular main body portion configured to be inserted into the sheath slidably along an axial direction of the sheath and an acting portion which is provided at a distal end of the main body portion and has a connection portion connected to the jaw, the connection portion positioned and configured to rotate the jaw according to a sliding action of the main body portion, wherein the sheath includes a notched portion positioned and configured to prevent the sheath from contacting a proximal portion of the jaw member when the connection portion of the driving member with the jaw moves in a direction perpendicular to a sliding direction of the driving member at a rotation time of the jaw, wherein the acting portion comprises a tapered shape portion gradually and gently narrowed toward a distal end of a tubular body of the main body portion; the tapered shape portion comprises a U-shaped extension portion with U-shaped in sectional configuration at the distal end of the tubular body of the main body portion; the U-shaped extension portion has two side faces disposed so as to be opposed to each other and a connected face connecting the two side faces; the connected face includes an inclined face where a distance between the two side faces is gradually tapered toward a distal end of the connected face; and the connection portion is formed on each of the two side faces disposed at distal ends of the connected face.
