PROBLEM TO BE SOLVED: To make a scissors type, a pen holder type and a shake hand type grip possible by reducing the weight and length. SOLUTION: The surgical instrument 10 is composed of two legs 11a and 11b substantially symmetrical with respect to a central axis L1, and the legs are a holding portion 13 on one end 10a side and a ring finger hole 14a on the other end 10b side. , 14b, and the leg portion is pivotally attached so that the holding portion can be opened and closed by the rotating shaft portion 12, and a ring finger hole is provided on the other end side as a position outside the curved line extending the leg portion. An engaging portion 16 and a spring 17 are provided between the two legs, and the central portion of the two legs along the central axis L1 is the grip portion 15.
