TREATMENT TOOL

摘要

A treatment tool comprising, a probe including a first surface that carries out incision of the living tissue with the ultrasonic vibrations, a second surface that carries out coagulation of the living tissue, and an insulation portion that covers the first surface, and a jaw which is engageable with the probe and disengageable from the probe, the jaw including a third surface facing the first surface in an engaging state and a fourth surface facing the second surface in the engaging state.

主权项

1. A treatment tool comprising:
a probe which is rod-shaped, which includes a first surface and a second surface that is provided in two places with the first surface interposed therebetween, the probe forms a first electrode to cause a high-frequency current to flow through a living tissue, and to which ultrasonic vibrations are transmitted; a jaw which is configured to engage with the probe and disengage from the probe, which includes a concave portion to house the probe, a third surface that is provided in the concaves portion and faces the first surface in a direction of rotation in a state of engaging with the first surface of the probe, and a fourth surface that is provided in the concaves portion and slanted to the third surface and faces the second surface in non-contact with the second surface in a state where the first surface and the third surfaces are engaged, and the jaw forms a second electrode to cause the high-frequency current to flow through the living tissue; and an insulation portion that covers the first surface.
