Abstract

There is disclosed an ultrasonic surgical instrument which comprises a sheath having a distal end and a proximal end and an ultrasonic probe to be inserted into the sheath, the ultrasonic probe having an interpolating portion positioned in the sheath and a hook-like treatment portion arranged in the distal end of the interpolating portion so that the treatment portion protrudes from the sheath, wherein the treatment portion has an extending portion which extends obliquely forward and downward from the upper portion of the distal end of the interpolating portion, and has a recess formed under the extending portion.

Claims

1. An ultrasonic surgical instrument comprising:

a sheath having a distal end and a proximal end; and

an ultrasonic probe to be inserted into the sheath, the ultrasonic probe having an interpolating portion positioned in the sheath and a hook-like treatment portion arranged in the distal end of the interpolating portion so that the treatment portion protrudes from the sheath,

wherein the treatment portion has an extending portion which extends obliquely forward and downward from the upper portion of the distal end of the interpolating portion, and has a recess formed under the extending portion.

2. The ultrasonic surgical instrument according to claim 1, wherein the treatment portion has a distal end hook portion which warps upwards from the distal end of the extending portion.

3. The ultrasonic surgical instrument according to claim 2, wherein a barycentric position of the treatment portion is located on the longitudinal axis of the ultrasonic probe.

4. The ultrasonic surgical instrument according to claim 2, wherein the treatment portion has an axially parallel portion extended substantially in parallel with the axial direction of the ultrasonic probe between the extending portion and the distal end hook portion.
