Abstract
A forceps cover sheath includes, detachably from a forceps, a cover sheath main body covering at least a link mechanism out of the forceps which has the link mechanism at a distal end portion of an elongated shaft and which has, at a distal end portion of the link mechanism, a treatment portion operated by operation of the link mechanism.

A forceps cover sheath comprising, detachably from a forceps, a cover sheath main body covering at least a link mechanism out of the forceps which has the link mechanism at a distal end portion of an elongated shaft and which has, at a distal end portion of the link mechanism, a treatment portion operated by operation of the link mechanism.
A forceps cover sheath comprising:
- a tubular cover sheath main body, the cover sheath main body being attachable to and detachable from an outer periphery of a link mechanism of a forceps including an elongated shaft, a link mechanism located at a distal end of the shaft;
- and
- a treatment portion component being attachable to and detachable from both distal ends of the link mechanism and the cover sheath main body, the treatment portion component being closed and being moved by the motion of the link mechanism in a state in which the component being attached to the both ends of the link mechanism and the cover sheath main body.
A surgical forceps comprising:
- an elongated insertion section having a distal and proximal end portions;
- a link mechanism provided at the distal end portion of the insertion section;
- a treatment portion which is coupled to the link mechanism and movable by operation of the link mechanism:
- an operating section which is provided at the proximal end portion of the insertion section and able to move the link mechanism by remote control;
- and
- a cover sheath having a tube member which is attachable to and detachable from an outer periphery of the link mechanism.
A surgical forceps comprising:
- an elongated insertion section having distal and proximal end portions;
- an operating section provided at the proximal end portion of the insertion section;
- a link mechanism which is provided at the distal end portion of the insertion section and able to move on the basis of operation of the operating section;
- a conducting portion which is provided at a distal end of the link mechanism and able to move in conjunction with the link mechanism by operation of the operating section;
- a conductive treatment portion which is attachable and detachable in a connected state electrically connected to the conducting portion and in an unconnected state detached therefrom and which is operated in accordance with operation of the link mechanism by the operating section in the connected state;
- a cover sheath having a tube member which is integrally connected to a the proximal end portion of the treatment portion and able to cover at least the link mechanism;
- and
- an electric connector which is provided in one of the insertion section and the operating section and which is electrically connected to the conducting portion to supply energy to the conducting portion and the treatment portion.
A surgical forceps system comprising:
- a forceps including an elongated insertion section having distal and proximal end portions, a treatment portion provided at the distal end portion of the insertion section, and a link mechanism which couples the treatment portion to the insertion section so that the treatment portion is able to be moved;
- and
- a forceps cover sheath including a tube member which changes shape in accordance with shapes of the insertion section, the treatment portion and the link mechanism and the tube member is attachable to and detachable from an outer periphery of the link mechanism.
A surgical forceps system comprising:
- a forceps including an elongated insertion section having distal and proximal end portions, a link mechanism provided at the distal end of the insertion section, a conducting portion provided at a distal end of the link mechanism, and an operating section which is provided at the proximal end of the insertion section and enables the link mechanism to move;
- and
- a forceps cover sheath including a tube member which changes shape in accordance with shapes of the insertion section and the link mechanism and which is able to cover at least an outer periphery of the link mechanism, and a treatment portion which is integrally attached to a distal end of the tube member and which is attached to the conducting portion to be operated by the operating section.
