1. An ultrasonic operating apparatus comprising:
- an elongate insert portion capable of being inserted into a body cavity;
an operating portion located on a distal end portion of the insert portion, the operating portion being used to operate an organism tissue;
a handling portion coupled to a proximal end portion of said insert portion, the handling portion having therein an ultrasonic vibrator capable of generating ultrasonic vibration;
a covering tube located around said insert portion;
a vibration transmitting member passed through the covering tube, the vibration transmitting member having an ultrasonic probe on a side of said operating portion and capable of transmitting the ultrasonic vibration from said ultrasonic vibrator to said ultrasonic probe;
a jaw rockably supported opposite said ultrasonic probe and capable of seizing the organism tissue in conjunction with said ultrasonic probe;
a control handle located in said handling portion and capable of opening and closing said jaw with respect to said ultrasonic probe; and
a handling force transmitting member coupling said jaw and said control handle, and capable of transmitting handling force from said control handle to said jaw, said jaw including a frame-shaped jaw body having at least supporting arms arranged individually on the opposite sides of a slot extending in an axial direction of said insert portion, a tip capable of seizing the organism tissue in conjunction with said ultrasonic probe, and a joint portion removably coupling said tip between said supporting arms of said jaw body.

5. A tool for changing a tip of an ultrasonic operating apparatus, comprising:
-
a tip changing tool body having an insertion hole into which a distal operating portion of said ultrasonic operating apparatus is inserted and a stopper portion for being the position of insertion of said distal operating portion inserted in the insertion hole;
a handling arm coupled to said tool body so as to be rockable around a hinge portion located on the inlet side of said insertion hole of the tool body; and
wedge-shaped separating portions adapted to be removably inserted into spaces between the tip for seizing an organism tissue and supporting arms on the opposite sides of a jaw body of said distal operating portion as the handling arm rocks, thereby moving said supporting arms in a direction such that indented fitting portions of said supporting arms and said tip are disengaged from one another.
