Adapter, extension, and connector assemblies for surgical devices
First Claim
1. An adapter assembly for operably connecting an end effector to a surgical instrument, the adapter assembly comprising:
- a first proximal shaft including a first gear assembly;
a second proximal shaft defining a longitudinal axis and including a second gear assembly;
a first distal shaft disposed along the longitudinal axis and extending distally from a third gear assembly, the first distal shaft spaced from the second proximal shaft, the first gear assembly being mechanically engaged with the third gear assembly such that rotation of the first gear assembly causes rotation of the third gear assembly; and
a second distal shaft including a fourth gear assembly, the second gear assembly being mechanically engaged with the fourth gear assembly such that rotation of the second gear assembly causes rotation of the fourth gear assembly, a distal portion of the second proximal shaft is disposed at least partially within an internal cavity of the third gear assembly.

Abstract
An adapter assembly for operably connecting an end effector to a surgical instrument. The adapter assembly includes a first proximal shaft, a second proximal shaft, a first distal shaft, and a second distal shaft. The first proximal shaft includes a first gear assembly. The second proximal shaft defines a longitudinal axis and includes a second gear assembly. The first distal shaft is disposed along the longitudinal axis and includes a third gear assembly. The first gear assembly is mechanically engaged with the third gear assembly. The second distal shaft includes a fourth gear assembly. The second gear assembly is mechanically engaged with the fourth gear assembly. A distal portion of the second distal shaft is disposed at least partially within an internal cavity of the third gear assembly.

17. A surgical instrument, comprising:
-
a first proximal shaft disposed in mechanical cooperation with a first gear assembly; a second proximal shaft defining a longitudinal axis and being disposed in mechanical cooperation with a second gear assembly, the second gear assembly being rotatable about the longitudinal axis with respect to the first proximal shaft; a first distal shaft disposed along the longitudinal axis and extending distally from a third gear assembly, the first distal shaft spaced from the second proximal shaft, the third gear assembly being rotatable about the longitudinal axis with respect to the first proximal shaft, the first gear assembly being mechanically engaged with the third gear assembly such that rotation of the first gear assembly causes rotation of the third gear assembly; and a second distal shaft including a fourth gear assembly, the second gear assembly being disposed in mechanical cooperation with the fourth gear assembly such that rotation of the second gear assembly causes rotation of the fourth gear assembly, a distal portion of the second proximal shaft being disposed at least partially within an internal cavity of the third gear assembly. - View Dependent Claims (18, 19, 20)
