Embodiment Construction

[0031] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0032] refer to Figure 1 ~ Figure 7A The first embodiment will be described.

[0033] Here, as a treatment instrument (energy treatment instrument) for treating living tissue by applying energy to it, for example, a linear bipolar treatment instrument 12 for treatment through the abdominal wall will be described as an example.

[0034] Such as figure 1 As shown, a therapeutic treatment system 10 includes a treatment implement (therapeutic treatment implement) 12, an energy source 14, and a foot switch 16 having a pedal 16a.

[0035] The treatment implement 12 includes a handle 22 , a shaft 24 having a central axis C, and a treatment portion 26 . On the handle 22 the energy source 14 is connected via a cable 28 . A foot switch 16 is connected to the energy source 14 . When the operator (user) operates the pedal 16 a of the foot switch 16 with his / her foot, ...

Abstract

A treatment device configured to hold a living tissue includes a swing member supported by a first grasping member and rotatable in a first direction and in an opposite direction opposite to the first direction. The swing member includes a distal end close to a distal end portion of the first grasping member and a proximal end close to the proximal end portion of the first grasping member, and a support shaft thereof is supported on a side close to the distal end including a middle position between the distal end and the proximal end. A first holding surface is provided on the swing member close to a side of the second grasping member and grasps the living tissue. A second holding surface is provided on the second grasping member close to a side of the swing member and which faces the first holding surface and which is configured to hold the living tissue together with the first holding surface of the swing member.

Description

technical field [0001] The present invention relates to a treatment instrument having a gripping surface for gripping living tissue. Background technique [0002] For example, US 2010 / 0057117 A1 discloses a first holding member that can be opened and closed relative to a second holding member (probe). The first clamping member is provided with a rotating member having a living tissue grasping surface for clamping the living tissue between the rotating member and the second clamping member. Therefore, the living tissue can be grasped with a more uniform force between the living tissue grasping surface of the rotating member and the living tissue grasping surface of the second clamping member. [0003] Since the rotating member provided on the first holding member rotates, the living tissue may easily escape toward the distal end side of the rotating member during the action of gripping the living tissue.
