Abstract

A powered surgical apparatus for engaging tissue includes a housing assembly and a movable portion operatively connected to the housing assembly. The movable portion is movable with respect to the housing assembly. In addition, the surgical apparatus includes a power source configured to supply electrical power, and a transmission system configured to transfer at least one of a signal and electrical power between the handle assembly and the movable portion, the transmission system including a first electronic board disposed in the handle assembly and a second electronic board positioned in the movable portion, the second electronic board including a primary control circuit and a secondary control circuit wherein the movable portion is configured and adapted to rotate about a longitudinal axis defined by the powered surgical apparatus.

Claims

1. A powered surgical apparatus for engaging tissue, the powered surgical apparatus comprising:

a housing assembly;

a movable portion operatively connected to the housing assembly, the movable portion being movable with respect to the housing assembly;

a tool assembly adapted to engage the tissue, the tool assembly being operatively coupled to the movable portion;

a power source configured to supply electrical power; and

a transmission system configured to transfer at least one of a signal and the electrical power between the housing assembly and the movable portion, the transmission system including a first electronic board disposed in the housing assembly and a second electronic board positioned in the movable portion, wherein the movable portion is configured and adapted to rotate about a longitudinal axis defined by the powered surgical apparatus.

2. The powered surgical apparatus of claim 1, wherein the transmission system is configured to transmit electrical power wirelessly between the housing assembly and the movable portion.
