Surgical robotic arm with wireless power supply interface
First Claim
1. A surgical robotic apparatus comprising:
- a surgical robotic arm having a proximal end portion and a distal end portion, where the distal end portion is configured to receive a surgical tool, and the proximal end portion is configured to be removably coupled to an adapter of a surgical robotic platform for surgery and decoupled from the adapter for storage; and
a secondary side of a resonant-mode transformer-coupled power converter that also has a primary side,wherein the secondary side of the power converter has a transformer secondary coil in the proximal end portion of the arm, and wherein the primary side has a transformer primary coil in the adapter, and wherein the primary and secondary coils are held at positions and orientations that enable mutual inductive coupling between them for operation of the power converter when the arm is coupled to the adapter.

Abstract
A proximal end portion of a robotic surgical arm is to be coupled to an adapter of a surgical robotic platform, for use during a surgical session at the platform, and then decoupled from the adapter for storage until being re-coupled for use during another surgical session at the platform. A resonant-mode transformer-coupled power converter is provided that has a secondary side and a primary side. The secondary side is in the arm and has a transformer secondary coil in the proximal end portion of the arm. The primary side has a transformer primary coil in the adapter. The primary and secondary coils are held at positions and orientations that enable mutual inductive coupling between them for operation of the power converter when the arm is coupled to the adapter. Other embodiments are also described and claimed.
