The present disclosure discloses a control handle, which includes an outer clamp arm control mechanism and an inner clamp arm control mechanism. The outer clamp arm control mechanism may be configured to control the movement of an outer clamp arm of a tissue clamping device, and include a sleeve, a first control part, and a sliding part. The sliding part may be disposed in the sleeve. The first control part may rotate to drive the sliding part to move in the sleeve along a length direction of the sleeve, so as to control the opening and closing of the outer clamp arm. The inner clamp arm control mechanism may be configured to control the movement of an inner clamp arm of the tissue clamping device, and include a housing and a second control part. The second control part may pass through and move along a second sliding groove to control the opening and closing of the inner clamp arm relative to the outer clamp arm.

A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

Treatment tool includes a fixed handle, a shaft extending distally from the fixed handle, a treatment portion projecting distally from the shaft and configured to treat biological tissue, a jaw pivotably rotatably with respect to the shaft and, with the treatment portion, configured to grasp the biological tissue therebetween, a movable handle extending proximally from the jaw and causing the jaw to open and close relative to the treatment portion by proximally approaching or separating from the fixed handle, and a first adjusting member provided on the movable handle and having an extension protruding toward the fixed handle and, when the movable handle is brought into close proximity to the fixed handle, abutting the fixed handle. Changing the amount (length) by which the extension of the first adjusting member protrudes from the movable handle, adjusts an amount of the stroke of the movable range of the movable handle.

Clamping forceps device includes two clamps in pivotal connection to one another and each having an operator end for being operated by a health care provider. The device also includes an extension extending aft of the operator end of each clamp, the extension forming a space therebetween sized to form a disconnecting wedge mechanism for separating a tube from a patient tube connector. Each extension defines a ramped surface increasing in thickness moving from an extension tip towards the operator end.

A tissue approximation device for wound closure having a first arm having a proximal end and a distal end, a second arm having a proximal end and a distal end, the second arm connected to the first arm. A first rake member is connected to the distal end of the first arm and has a first plurality of tissue engaging members extending therefrom to engage tissue. A second rake member is attached to the distal end of the second arm, the second rake member having a second plurality of tissue engaging members extending therefrom to engage tissue. A transverse bar can extend through the first and second rake members such that the first and second rake members movable along the transverse bar. Systems and methods for wound closure are also disclosed.

A surgical instrument system comprising a handle, a shaft, and a disposable power module is disclosed. The handle comprises a motor, a control switch, and a motor-control processor which is in communication with the control switch. In various instances, the disposable power module comprises a disposable battery and a display unit configured to indicate at least one function of the surgical instrument system.

Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.

An apparatus for removing a hook embedded within a tissue is presented. The hook has a barb extending from a point section of the hook. The apparatus includes a clamping device configured to secure the hook. A probe is coupled to the clamping device. The probe has a tip portion configured to fit within a space between the barb and the point section of the hook to allow the hook to be removed from the tissue.

A surgical clip applier is disclosed which is configured to automatically feed a clip from a clip cartridge once the surgical clip applier is positioned in the patient.

A forceps includes an end effector assembly having first and second jaw members disposed in parallel orientation relative to one another. One or both of the jaw members is movable along a first axis relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween. The first and second jaw members are configured to maintain the parallel orientation therebetween upon movement of the jaw members between the spaced-apart and approximated positions. A drive bar is coupled to one or both of the jaw members. The drive bar is selectively movable along a second axis that is different from the first axis between first and second positions for moving the jaw members between the spaced-apart and approximated positions.
