FIELD: medicine. ^ SUBSTANCE: group of inventions relates to surgical sewing instruments, which are able to apply lines of staples on tissue. Surgical instrument includes end working organ, shaft, elongated triggering element, rotor transmission and handle. End working organ functionally is made for responding to activating movement. Shaft is fixed to operating organ and includes elongated triggering element, which is connected with working organ for movement with longitudinal transmission of triggering movement. Handle is proximally fixed to shaft. Rotor transmission includes inlet rotor element, connected with start drive for rotation in accordance with, at least, triggering movement. Outlet rotor element is in gear with elongated triggering element for rotation in accordance with its longitudinal movement. Unilateral sleeve functionally is made for detaching outlet rotor element from start drive when start drive is moving in reverse direction between triggering pressings. ^ EFFECT: invention creates multiple triggering pressings in order to reduce required effort necessary for triggering (ie application of staples and tissue dissection) operating body. ^ 15 cl, 20 dwg |
