Problems solved by technology

Therefore, when the cutting length of the living tissue to be cut is relatively long, the stroke of moving the knife becomes long, that is, the operation stroke of the operator needs to be extended, and the operability is reduced.
In addition, even if the movement stroke of the tool is enlarged by using a lever with respect to the operation stroke, the operation force increases and the operability decreases.
In this way, it is sometimes difficult to move the tool axially for a relatively long distance

Embodiment Construction

[0038] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0039] refer to Figure 1A ~ Figure 9B The first embodiment will be described.

[0040] Such as Figure 1A As shown, the treatment system 10 of this embodiment has a treatment tool 12 and a controller 14 for applying power to the treatment tool 12 . The controller 14 controls the temperatures of the first energy output unit 62 and the second energy output unit 64 described later of the treatment tool 12 to be appropriate temperatures. In addition, in this embodiment, although the example which has the controller 14 was demonstrated, the controller 14 is not necessarily essential. That is, the 1st energy output part 62 and the 2nd energy output part 64 mentioned later are not necessarily essential.

[0041]The controller 14 is connected to a foot switch 16 having a pedal 16 a for switching ON / OFF of the thermal energy applied to the treatment tool 12 . The tr...

Abstract

A treatment device to treat a living tissue, includes: first and second holding portions including a longitudinal axis and including respective holding surfaces opening and closing in an opening / closing direction orthogonal to or substantially orthogonal to the longitudinal axis and capable of holding the living tissue therebetween; a rotary member including a working portion including an edge portion capable of cutting the living tissue by being rotated around a central axis equal to or substantially parallel with the longitudinal axis, the rotary member capable of moving the edge portion from the first holding portion to the second holding portion; a first guide portion provided in the first holding portion and capable of guiding the edge portion toward the second holding portion through the holding surface of the first holding portion; and a second guide portion provided in the second holding portion, and capable of guiding the edge portion to the second holding portion through the holding surface of the first holding portion, the second guide portion capable of cutting the living tissue in guiding the edge portion to the second holding portion through the holding surface of the first holding portion.

Description

technical field [0001] The present invention relates to a treatment instrument for cutting and other processing of living tissue. Background technique [0002] For example, the treatment unit of the treatment tool disclosed in Japanese Patent Application Laid-Open No. 2001-170070 can cut the grasped living tissue by moving a knife in the axial direction while holding the living tissue. [0003] In this treatment tool, when moving the cutter in the axial direction, it is necessary to move the operation portion by an operation stroke close to the cutting stroke. Therefore, when the cutting length of the living tissue to be cut is relatively long, the stroke for moving the knife becomes long, that is, the operation stroke of the operator needs to be extended, and the operability decreases. In addition, even if the movement stroke of the tool is enlarged by using a lever with respect to the operation stroke, the operation force increases and the operability decreases. In this ...
