PROBLEM TO BE SOLVED: To provide puncture needle forceps including a trocar function being easily inserted in a multilayer-structured abdominal wall formed by superposing multiple fascias, and forming a small surgical wound for an endoscopic surgical operation.SOLUTION: Small-diameter forceps including a small-diameter shaft 2 extending from a handle part 1, and a grip part 3 at the distal end of the small-diameter shaft 2, comprises a trocar 4 to be locked at a position wrappingly protecting the distal grip part 3. The trocar 4 is configured to be locked at the position wrappingly protecting the distal grip part 3, to freely, slidingly fit the small-diameter shaft between a locking position 5 and the handle part, and to be pressedly stopped, by a press-stopping button 6, at an any position between the vicinity of the handle part or the locking part for wrappingly protecting the end grip part, and the handle part. A large-diameter part of the trocar 4 has a groove 7 that is fixable to the abdominal wall or the like by a thread knot or the like. The large-diameter part includes the small-diameter shaft 2 extending from the handle part 1, and the grip part 3 at the distal end of the shaft. The small-diameter forceps include the trocar 4 and directly insert in the abdominal cavity or reinsert the once-extracted forceps into the same puncture hole. |
