PURPOSE: To permit a dynamic configuration such that stresses are appropriately transmitted to opening/closing members. CONSTITUTION: In surgical equipment, particularly for endoscopy, having an opening/closing mechanism comprising opening/closing members such as forceps pieces or incisor pieces secured to a towing member 2, at least one of the opening/closing members (7 or 8) is supported in such a way as to be rotatable about rotating shafts 16, 29, an extraction shank 2 passes through a shaft tube 1, and a notched part (14 or 14a) is formed in at least one of the opening/closing members, with its center point M rotated about the rotating shafts 16, 29. The notched part (14 or 14a) surrounds an annular part 25 formed on the side wall of the shaft tube 1 during use, and the opening/closing members 7, 8 make opening and closing movements about the annular part 25. |
