  • Apparatus and method for measuring pressure between jaw members
    Patent number: 8215182
    Abstract: Testing system for measuring closure pressure between jaw members of electrosurgical forceps. The testing system includes a testing platform, a pair of selectively adjustable instrument supports, a testing stand. The platform has an elongated bed that supports an instrument rest, which supports the electrosurgical forceps. The pair of instrument supports are associated with the elongated bed and secure the forceps atop the elongated bed. The testing stand is disposed at a distal end of the elongated bed and supports a piece of testing material. The testing stand includes a layer of visco-elastic material and a pressure sensitive film. The layer of visco-elastic material forms a pocket. The pressure sensitive film is disposed within the pocket of the visco-elastic layer. The pressure sensitive film is adapted to electromechanically communicate with a diagnostic system to measure the closure pressure between jaw members when they are in a clamped configuration.
