Probe unit, treatment instrument, and treatment system
First Claim
1. A probe unit for treating a bone surrounded by living tissue, the probe unit comprising:
- a probe configured to treat the bone by ultrasonic vibration;
a hollow sheath surrounding the probe, the hollow sheath including;
a first portion disposed at a first distance from a central axis of the hollow sheath and having a first diameter, anda second portion disposed at a second distance from the central axis that is greater than the first distance of the first portion, the second portion having a second diameter that is longer than the first diameter of the first portion and intersects the first diameter of the first portion at right angles; and
a knob configured to rotate the hollow sheath relative to the probe; and
a circular-ring-shaped balloon attached to an outer circumferential surface of the hollow sheath in vicinity of a distal end of the hollow sheath, the circular-ring-shaped balloon being configured to be inflated and deflated.

Abstract
A probe unit includes, a probe configured to treat a bone by ultrasonic vibration, a hollow sheath which surrounds the probe and which has a first portion at a small distance from a central axis, and a second portion at a greater distance from the central axis than the first portion, and a knob configured to rotate the sheath relative to the probe between a first position for insertion between the bone and a living tissue facing the bone so that the first portion is located between the bone and the living tissue and a second position for insertion between the bone and the living tissue so that the second portion is located between the bone and the living tissue.
