  • Patent number: 10987155
    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.

  • Patent number: 8540231
    Abstract: A paper stopper mechanism for paper-feeding apparatus, which has simplified structure and commonly uses one motor to stop papers. The paper stopper mechanism includes a rotary shaft driven by a drive shaft via a gear assembly, a stopper plate disposed on the rotary shaft, which is movable between a first position and a second position along with the rotation of the rotary shaft, and a resilient member positioned between the rotary shaft and a transmission gear of the gear assembly. There is frictional force between the rotary shaft and the transmission gear, whereby the transmission gear can drive the rotary shaft to rotate. When the stopper plate and the rotary shaft stop at the second position, the transmission gear can still transmit power to a pickup roller to feed a paper into the paper-feeding apparatus without any error.
