Patent attributes
An apparatus for supporting a patient's arm in a desired position during surgery includes a patient support, such as an surgical table or chair, an arm support for supporting the patient's arm, an arm support locking mechanism for securing the arm support in a desired position during surgery, and a bracket for attaching the arm support and the arm support locking mechanism to the patient support. The arm support locking mechanism includes first and second plates having notches or projections for securing the mechanism in a locked position. One of the plates also has an angled recess region for engaging a wedge-shaped member positioned between the plates in the locked position. In operation, the wedge-shaped member moves one of the plates against a force of the spring to unseat the projections from the notches in an unlocked position allowing for rotation of the arm support in two directions.
