  • Patent number: 10595927
    Abstract: A combination medical includes a first arm and a second arm interconnected to the first arm. The first arm and the second arm are biased towards each other by a closing force. A biasing member is disposed between the first arm and the second arm. The biasing member has a first position that biases the first arm and the second arm away from each other against the closing force and a second position that does not oppose the closing force. The combination medical device may be an electrosurgical device with a mono-polar and bi-polar configuration.

  • Publication number: 20170340379
    Abstract: A surgical device includes a forceps and a blade. The forceps includes a first working jaw and a second working jaw. The blade extends along a longitudinal axis and includes a notched section. The blade is located between the first working jaw and the second working jaw. A first therapy current can be connected to the first working jaw, the second working jaw, or both so that tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated. While the tissue is gripped between the first working jaw and the second working jaw, the blade is moveable along its longitudinal axis so that the tissue is cut with the notched section without repositioning the first working jaw, the second working jaw, or both.
