Abstract
Bipolar forceps of the type where each of the prongs has a manually engageable portion spaced from the tip for manual squeezing of the prongs and an electrical supply system for applying a high-frequency electric current between tool tips to dissect through tissue planes and/or seal blood vessels includes a set of force measuring sensors for measuring forces, particularly squeezing forces, applied to the prongs at the tip. A temperature sensor is included to provide temperature information and temperature compensation. The sensors are applied to each prong in opposing pairs on the inside and outside surfaces and the outputs thereof are applied to a bridge arrangement. The signals are sent to a processor for generating warning signals and for recording forces for training purposes where a haptic system can be used.
