Force Sensing System for Surgical Self-Retaining Retractors

This invention is a single self-retaining retractor with an autoclave force sensor mounted on each side of the retractor at the tissue interface. A force sensor is connected to a processing circuit via autoclave wires and a thermocouple. The processing circuit is connected via a Bluetooth low energy (BLE) with a mobile application to display store and...
