The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

A treatment instrument that includes a first grasping member having a first grasping surface and a second grasping member having a second grasping surface. The treatment instrument includes a cover that covers at least a part of a region of at least one of the first and second grasping members other than the first and second grasping surfaces, and a pair of electrodes that are arranged on at least one of the first and second grasping surfaces to function as a bipolar electrode. An opening is provided in the cove, and a monopolar electrode arranged to overlap with the opening and is exposed to an outside of the treatment instrument through the opening.

A surgical forceps comprising: a first working arm and a second working arm configured to move towards and away from each other; and an electromagnetic latching system; wherein the electromagnetic latching system is configured to create a force that is in a direction aligned with closing of the forceps or opposite to the closing of the forceps when an electromagnetic activation button is depressed.

The disclosed technology is directed to a surgical instrument comprises a sheath having respective opposed proximal and distal ends. A pair of grasps is disposed on the distal-end portion of the sheath gripping a treatment target therebetween. A drive shaft is coupled to at least one of the pair of grasps to open or to close the pair of grasps by being moved along the longitudinal axis with respect to the sheath. Electric elements are used to apply treatment energy to the treatment target. A first operating device supplies the electric energy to the electric elements in a first supply state. A first member produces a force to open or close the pair of grasps and applies the force to the drive shaft. A second member is disposed in line with the first member and applies a force to the drive shaft in response to the operation input.

A gearbox assembly for a surgical instrument includes an articulation sub-assembly and a jaw drive sub-assembly. The articulation sub-assembly is configured to articulate an end effector of the surgical instrument and the jaw drive sub-assembly is configured to move jaw members of the end effector between an open and closed position. The articulation sub-assembly includes two input shafts, a proximal plate, a middle plate, two center gears, and four lead screws with four nuts. The jaw drive sub-assembly includes a drive rod coupled to at least one of the jaws and a spring force assembly to maintain a force between the jaws.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

A surgical device includes a housing, an elongated shaft, an end effector, and an actuation mechanism. The housing pivotally supports a movable handle between unactuated, first actuated, and a second actuated positions. The elongated shaft extends distally from the housing and defines a longitudinal axis. The end effector has a pair of opposed jaw members that are movable between an open configuration in which the jaw members are spaced apart from one another and a closed configuration in which the jaw members are closer together. The actuation mechanism is configured to transition the end effector between the open and closed configurations as the movable handle is pivoted between the unactuated and first actuated positions and to maintain the end effector in the closed configuration when the moveable handle is between the first and second actuated positions.

A surgical instrument having a first jaw and a second jaw arranged in a hinged manner with respect to each other. A tool is slidably supported in a longitudinal direction in a tool channel, preferably in or on the first jaw. The tool may be moved in longitudinal direction by an actuation device. The actuation device has an actuation element and a drive element that are pivotably supported around a pivot axis, preferably on the first jaw. A rotational coupling may be established between the actuation element and the drive element via a coupling device.

In one example, a medical device may be adapted for use with a delivery device, and the medical device may include a handle including at least one actuator; a body adapted to releasably mount to a distal portion of the delivery device, the body supporting a pair of jaws rotatably coupled to the body; and a control wire coupled to the pair of jaws and the actuator. The actuator may be configured to open and close the pair of jaws.

A fluid supply instrument for a treatment instrument that is mounted on a grasping section of the treatment instrument capable of grasping a living tissue includes a port configured to receive a fluid, and a cover continuous to the port and configured to be covering a back surface on an opposite side of a grasping surface of the grasping section that is capable of grasping a living tissue. The cover forms a fluid channel continuous from the port in cooperation with the grasping section, and allows the fluid received from the port to flow out from between a cover edge adjacent to the grasping surface and an edge portion of the grasping surface.
