    摘要: A laparoscopic device assembly provides a tubular diaphragm twist seal that responds to a slight rotation of an actuating ring in a first direction by coupling a motor spring power assisted rotation of a bottom circumference of the twist seal achieves a pneumatic seal in an adjustable access channel defined by the state of the twist seal for maintaining an insufflated body cavity for a hand assisted laparoscopic surgical procedure. A slight rotation of the actuating ring in an opposite second direction releases compression spring energy and energy in the twisted state of the twist seal so that an upper circumference of the twist seal is allowed to open the adjustable access channel.
