First Claim
Patent Images
1. A pinion clip operable with a drive shaft and pinion assembly, the pinion clip configured to engage a pinion defining a longitudinal axis and having an internal bore, the pinion clip comprising:
- two arms adapted to be disposed along the longitudinal axis of the pinion; and
a base member defining a base axis and two base posts, the base axis in perpendicular orientation to the longitudinal axis of the pinion, and the base member further defining an aperture centrally disposed thereon such that the two base posts are in opposed relation to each other along an axis defined by the aperture;
wherein the pinion clip is adapted to be positioned on the pinion such that the two arms are adapted to intersect a diameter of the internal bore of the pinion; and
wherein the two base posts of the base member are adapted to secure the pinion clip to the pinion.

Abstract
Coupling assemblies are provided for maintaining a secure connection between surgical devices utilizing a shaft-and-pinion configuration and powered drive shafts. The coupling assemblies include a clip to be disposed without or within a pinion for receiving and securing a drive shaft member. The coupling assemblies are designed to maximize restriction of movement between the drive shaft and clip, but avoid impeding the rotational motion of a pinion.
