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.

Claims

1. A probe unit comprising:

a probe configured to treat a bone by ultrasonic vibration;

a hollow sheath surrounding the probe, the sheath including;

a first portion disposed at a small distance from a central axis of the sheath and having a short diameter,

a second portion disposed at a greater distance from the central axis than the first portion and having a long diameter such that the long diameter of the second portion intersects the short diameter of the first portion at right angles, and

a tapered portion provided on a distal side of the sheath, the tapered portion being smaller in diameter as the distance to a distal end of the sheath decreases; and

a knob having a diameter larger than that of the sheath, the knob being configured to rotate the sheath relative to the probe between;

(i) a first position for insertion between the bone and the living tissue facing the bone so that the first portion is located between the bone and the living tissue, and (ii) 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, wherein;

the length of the tapered portion along a longitudinal axis direction of the probe is greater than the diameter at a distal end of the tapered portion, and

a surface of the tapered portion is curved to become parallel to the longitudinal axis of the probe as the distance to the distal end of the sheath decreases.

2. A probe unit comprising:

a probe configured to treat a bone by ultrasonic vibration;

a hollow sheath surrounding the probe, the sheath including;

a first portion disposed at a small distance from a central axis of the sheath and having a short diameter,

a second portion disposed at a greater distance from the central axis than the first portion and having a long diameter such that the long diameter of the second portion intersects the short diameter of the first portion at right angles, and

a tapered portion provided on a distal side of the sheath, the tapered portion being smaller in diameter as the distance to a distal end of the sheath decreases; and

a knob configured to rotate the sheath relative to the probe between;

(i) 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 (ii) 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, wherein;

the tapered portion has a groove, and the groove extends in a direction that intersects with a longitudinal axis direction of the probe.

3. A probe unit comprising:

a probe configured to treat a bone by ultrasonic vibration;

a hollow sheath surrounding the probe, the sheath including;

a first portion disposed at a small distance from a central axis of the sheath and having a short diameter,

a second portion disposed at a greater distance from the central axis than the first portion and having a long diameter such that the long diameter of the second portion intersects the short diameter of the first portion at right angles, and

a tapered portion provided on a distal side of the sheath, the tapered portion being smaller in diameter as the distance to a distal end of the sheath decreases; and

a knob configured to rotate the sheath relative to the probe between;

(i) 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 (ii) 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, wherein;

the tapered portion has a groove, and the groove radially extends around a longitudinal axis of the probe.
