Beschreibung
Zusammenfassung:	The power assisting device for the spiral skin expander comprises a sleeve, a grab handle is formed at the closed end of the sleeve, and the maximum distance L between the edge of the grab handle and the central axis of the spiral skin expander is larger than the maximum radius R of the spiral skin expander. And a through guide wire tunnel is formed along the central axis of the sleeve. The grab handle is arranged, and the maximum distance L from the edge of the grab handle to the central axis of the spiral skin expander is larger than the maximum radius R of the spiral skin expander, so that the length of a force arm generated when a doctor holds the grab handle and twists the grab handle around the central axis of the spiral skin expander is larger than the length of a force arm generated when the doctor holds the spiral skin expander and twists the spiral skin expander around the central axis of the spiral skin expander. And the longer the force arm is, the more labor-saving is, so that compared with the p
