Abstract
A treatment device includes: an operating section; an elongated insertion section connected to the operating section; a pair of clamp members provided at the distal end of the insertion section so as to be openable and closable relative to each other; a movable member that is moved so as to push staples relative to tissue sandwiched between the clamp members; and a coil member that is arranged so as to pass through the insertion section in the longitudinal direction and that transmits a pressing force from the operating section to the movable member.
Claims12
A treatment device comprising:
- an operating section operated by an operator;
- an elongated insertion section that is connected to the operating section and that has flexibility;
- a stitching section that is provided at a distal end of the insertion section and that includes a first clamp member that accommodates staples and a second clamp member that is provided so as to be openable and closable relative to the first clamp member;
- a first movable member that is provided in the first clamp member of the stitching section and that is moved so as to push the staples relative to tissue sandwiched between the first clamp member and the second clamp member;
- and
- a coil member that is provided so as to pass through the insertion section in a longitudinal direction, the distal end of which is brought into contact with the first movable member, and that transmits a pressing force applied in the operating section.
The treatment device according to 5, wherein the first clamp member includes a guide groove for guiding the movement of the first movable member.
The treatment device according to 6, wherein the first movable member includes a slider section that slides in the guide groove, and
- the slider section is shaped so as to be in contact with each side wall of the guide groove at two positions with a space interposed therebetween in the slide direction of the slider section.
The treatment device according to 2, wherein the first movable member and the second movable member are provided independently of one another so that the staples and the cutter are pushed individually.
The treatment device according to 2, wherein the first movable member and the second movable member are provided so as to push the staples and the cutter simultaneously.
A treatment device comprising:
- an operating section operated by an operator;
- an insertion section that is connected to the operating section and that is inserted into a body;
- a first clamp member that is provided at a distal end of the insertion section and a second clamp member that is provided so as to be openable and closable relative to the first clamp member;
- a cutter for cutting tissue sandwiched between the first clamp member and the second clamp member of the stitching section;
- a movable member that is provided in the first clamp member and that is moved so as to push the cutter relative to the tissue sandwiched between the first clamp member and the second clamp member;
- and
- a coil member that is provided so as to pass through the insertion section in a longitudinal direction, the distal end of which is brought into contact with the movable member, and that transmits a pressing force applied in the operating section.
