Abstract: An electrosurgical return pad including a material backing configured to support first and second conductive materials and an insulative layer disposed therebetween. A switch element is mounted on the first conductive material and is activatable upon reaching a threshold condition, such as temperature. Upon reaching the threshold condition, the switch element automatically activates to provide electrical continuity between the first and second conductive materials to offset the threshold condition.

Abstract: A torque apparatus for the installation and removal of threaded connecting device that employs a plurality of leaf spring elements engaging a plurality of asymmetrical drive teeth sides to establish preset torque values in a hermetically sealed configuration or a variable range of preset torque values in a second configuration. The preset torque values can be readily changed in the second configuration by employing different quantities of leaf springs, differing leaf spring designs, or varying the geometry of the rotor drive teeth. The leaf spring to rotor drive teeth interface provides a slip mechanism to prevent over-torquing when torque values for the installation of a threaded connecting type device is exceeded. While both torque wrench configurations are sterilizable, the torque wrench that is capable of full disassembly for sterilization and use thereafter in a sterilized environment, is reconfigurable for different torque applications without calibration.
