Valve for at least one suction and/or rinsing channel of a surgical instrument

摘要

valve equipment (10) for at least one suction and/or rinsing channel of a surgical instrument, in particular for endoscopic surgery with a housing (20) with a handle (49) and with a cylindrical aperture (32),which has an inner wall (33) and a valve body arranged in the cylindrical passage opening (32),which has a cylindrical outer wall (63)and is rotatable and axially shiftable in the passage opening (32), where a sealing effect between the housing (20) and the valve body (60) is achieved by the interaction of a section of the inner wall (33) of the passage opening (32) with a section of the outer wall (63) of the valve body (60), where the housing (20) has at least one opening in the inner wall (39) and the valve body (60) at least one valve opening in the cylindrical outer wall (63) (65, 66, 67);where, by moving the valve body (60) in the housing (20), one of the valve openings (65, 66, 67) is overlapping or not overlapping with one of the housing openings (35, 36) and where a breakthrough (44) is arranged in the housing (20), by which a control element located on the valve body (60) is guided to the outside of the housing (20) and in which the control element (70) is moved, the game between the valve body (60) and the passage opening (32) of the housing (20) is less than 15m.
