Abstract

This medical device has: a jaw that is provided with a gripping portion; and a blade that can be made to approach and separate from the gripping portion, extends from a tip portion to a base end portion, and has a top portion that includes an edge at a position opposing the gripping portion, wherein the curvature radius of the top portion at the tip portion is larger than the curvature radius of the top portion at the base end portion.

Description

technical field [0001] The present invention relates to a medical device capable of handling living tissue while grasping it. Background technique [0002] For example, in the treatment tool disclosed in JP-A-2001-198137, the treatment part is formed to be sharper at a position closer to the gripping surface of the other forceps among the gripping surfaces of one forceps. The treatment part conducts heat to the grasping surface in a state where pressure is applied to the living tissue to be incised by the sharp part of the grasping surface of one forceps, and coagulates (seals) the living tissue to be treated while Cut it open. [0003] When the living tissue is clamped by the front end of the treatment part of the treatment instrument disclosed in Japanese Patent Application Laid-Open No. 2001-198137, a relatively large pressure is applied to a small area of ​​the living tissue by using the sharp part of the grasping surface of one forceps . That is, when the living tiss...
