Abstract
This medical treatment tool includes: an end effector which has a first forceps piece and a second forceps piece; an operating member that the pair of forceps pieces to rotate and opens/closes; and a link member whose distal end portion is coupled to the forceps piece, and whose proximal end portion is coupled to the operating member; wherein the drive axis of the proximal end portion is parallel with the axis of the operating member; the distance between the distal end portion and the drive axis of the proximal end portion is shorter than the length of the link member; and the length of projection on the drive axis is shorter than the length of projection on the drive axis of a line segment which connects the distal end portion and the center of rotation.
Claims7
A medical treatment tool, comprising:
- an end effector which has a pair of jaw member of which at least one is supported so that it is capable of being rotated relative to a base;
- an operating member which is configured to move to advance or retract in its own axial direction relative to the base so that the pair of jaw members rotates and opens/closes;
- and a first end portion of a link member is rotatably coupled to the jaw member, and a second end portion of the link member is connected to the operating member;
- wherein a drive axis of the second end portion is parallel with an drive axis of the operating member;
- a distance between the first end portion and the drive axis of the second end portion is shorter than the length of the link member;
- and a length of projection on the drive axis of a line segment which connects the second end portion and a center of rotation of the pair of jaw members is shorter than the length of projection on the drive axis of a line segment which connects to the first end portion and the center of rotation.
