Abstract
This invention reduces the amount by which members protrude to the outside of a forceps for endoscope that can perform an oscillating operation, and reduces the amount of contact between an organism and parts other than the surgical instruments, thereby maintaining the visual field of the endoscope. The forceps for endoscope comprises an insertion section that is inserted inside a body cavity, an openable and closable forceps section provided at the tip of the insertion section, and a operation section for controlling the forceps section. The forceps section comprises a first forceps member, and a second forceps member, which faces the first forceps member and can rotate with a first pivotal supporting member as a fulcrum; the second pivotal supporting member supports the first forceps member from vertically above it so that it can rotated freely around an oscillating operation axis member, and is provided between the oscillating operation axis member and an opening-closing operation axis member. A third pivotal supporting member supports the first forceps member from vertically outside, so that it can rotate around the oscillating operation axis member.
