TLDR
In this article, a retraction mechanism for surgical stapling is presented, which includes a motor coupled to a transmission shaft, a first gear rotatably mounted on the transmission shaft and a second gear operatively attached to the second gear.Abstract:
A surgical stapling apparatus comprises a handle assembly, an actuation shaft having a connector, and a retraction mechanism positioned within the handle assembly. The retraction mechanism includes a motor coupled to a transmission shaft, a first gear rotatably mounted on the transmission shaft, the first gear configured to engage a second gear, a clutch operatively attached to the second gear, a main shaft rotatably connected to the clutch, and a pulley coupled to the main shaft, the pulley being operatively attached to the connector. The connector and the pulley may be attached via a cable. The retraction mechanism may include a spring motor for maintaining the cable in tension. The spring motor may have a spring element wrapped around and interconnecting at least two arbors.read more
