Abstract

An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.

First claim

The invention claimed is:

1. An arthroscopic surgery method for ankle ligament reconstruction comprising:
a probe that defines a longitudinal axis and transmits ultrasonic vibration; and
a treating portion provided on a distal portion of the probe, the treating portion including a distal surface that intersects with the longitudinal axis, a first projection that projects from the distal surface along the longitudinal axis, and a plurality of second projections that project from the distal surface along the longitudinal axis and have a shorter projecting length than the first projection,
the method comprising:
forming a guide hole in each of a fibula, a talus, and a calcaneus;
inserting the first projection into the formed guide hole;
moving the first projection along the guide hole so that a bone hole that is larger than the guide hole is formed in each of the fibula, the talus, and the calcaneus by the second projections that outputs the ultrasonic vibration; and
fixing a tendon to the formed bone hole.

2. The method according to claim 1 , wherein:
the treating portion of the ultrasonic treatment device further comprises a plurality of third projections or an edge on a side surface, and
the method further comprises removing a persistence ligament by the third projections or the edge before forming the guide hole.

3. The method according to claim 1 , wherein the first projection is disposed in a center of the distal surface.

4. The method according to claim 1 , wherein the bone hole is elliptic.

5. The method according to claim 1 , wherein the bone hole is round.

6. The method according to claim 1 , wherein the guide hole is formed by a treatment device being an ultrasonic treatment tool.

7. The method according to claim 1 , wherein the guide hole is formed by a treatment device being a surgical instrument.

8. A method of forming a hole for fixing a tendon to a bone comprising:
a probe that defines a longitudinal axis and transmits ultrasonic vibration; and
a treating portion provided on a distal portion of the probe, the treating portion including a distal surface that intersects with the longitudinal axis, a first projection that projects from the distal surface along the longitudinal axis, and a plurality of second projections that project from the distal surface along the longitudinal axis and have a shorter projecting length than the first projection,
the method comprising:
forming a guide hole in the bone;
inserting the first projection into the formed guide hole; and
moving the first projection along the guide hole so that a bone hole that is larger than the guide hole is formed by the second projections outputting the ultrasonic vibration.

9. The method according to claim 8 , wherein the guide hole is formed by a treatment device being an ultrasonic treatment tool.

10. The method according to claim 8 , wherein the guide hole is formed by a treatment device being a surgical instrument.
