Publication number: 20210145506Abstract: A device including forceps having first and second working arms, a blade, and an arm securing mechanism having an electromagnetic latch. Distal ends of the first and second arms are biased toward each other by a first force when the electromagnetic latch is energized. The device is switchable between a first configuration where the distal ends of the arms are biased away from each other and the blade is proximal to the distal ends of the arms; a second configuration where the distal ends of the arms are biased toward each other by the first force and the blade is proximal to the distal ends of the arms; and a third configuration where the distal ends of the arms are biased toward each other by the first force and the blade is substantially flush with or extends beyond the distal ends of the arms.Type: ApplicationFiled: November 30, 2020Publication date: May 20, 2021Inventors: Kester Julian Batchelor, Richard J.

Patent number: 10939953Abstract: 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.Type: GrantFiled: August 18, 2017Date of Patent: March 9, 2021Assignee: Gyrus Acmi, Inc.Inventors: Kester J.

Patent number: 10595927Abstract: 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.
