A device includes a push rod that extends through a portion of a shaft, and an end of the push rod is translated by rotating a lever. The device further includes a needle assembly coupled to an end of the shaft, and the needle assembly includes a first needle arm and a second needle arm that are pivotable between a first open position and a second closed position. When the lever is rotated by a user, the end of the push rod is configured to contact a portion of the needle assembly to displace the needle assembly from a first open position into a second closed position.

Closure systems and members for actuating jaws of a surgical end effector. The closure systems include a closure member that is configured to interact with corresponding portions of the jaws to establish improved closure and clamping loads.

A surgical stapling device includes a tool assembly that includes an anvil assembly and a cartridge assembly. The cartridge assembly includes a channel member that includes structure for releasably engaging the anvil assembly to allow for separation of the entire cartridge assembly from the anvil assembly after each use of the stapling device.

A surgical stapling device includes a tool assembly having an anvil, a cartridge assembly movable in relation to the anvil between open and clamped positions, a drive member, and a biasing mechanism or member. The biasing mechanism or member is configured to urge the cartridge assembly in relation to the anvil assembly to its fully open position to provide access to tissue during a surgical procedure.

A surgical clamping device is disclosed, having a first clamp jaw and a second clamp jaw, each having one or more channels configured for receiving suture for reliably securing the clamp jaws to maintain a clamping pressure during a surgical procedure, as well as to reliably and releasably secure the clamp jaws onto the introducer shaft of the clamping device. Also described are clamp jaws having one or more actuator interfaces and alignment guides configured for reversible and slidable engagement with an actuator at the end of an articulating introducer shaft. Also described are various features of clamp jaws for use with a surgical clamping device. Also disclosed is a surgical clamping device having detachable, pivotable first and second clamp jaws releasably held on pivotable fingers at a proximal end of an articulating introducer shaft. Related methods of surgical clamping procedures are also disclosed.

Described here are methods, systems, and devices, useful for minimally invasive surgical procedures. The methods may include introducing a grasper through an opening into an abdominal cavity, grasping a portion of a left lobe of a liver with the grasper, rotating the grasper towards a control element located outside the abdominal cavity by applying a magnetic field to the grasper across a body wall, and moving the control element over a set of ribs such that the liver bends into a folded configuration.

An anvil for a surgical stapler. In at least one form, the anvil includes an elongate anvil body portion that has an upper portion and a staple forming undersurface. An anvil mounting portion is adjacent to the elongate anvil body and is configured to movably support the anvil on a portion of the surgical stapler. An anvil cap is configured to be mechanically interlocked to the upper portion of the elongate anvil body. At least one weld is provided between the anvil cap and the upper portion of the elongate anvil body portion.

The present invention relates to a medical instrument, and particularly relates to a hemostatic clip device. The device includes a clamping component and a holder component. The head portion of the sleeve is provided with open slots for clamping arms to move. The tail ends of the outer side edges of clamping arms each is provided with a recess. A hole, corresponding to the position of the recess of one clamping arm, is formed in the other one. The sleeve is connected with the sleeve holder through inner core. The head end of the double-wire supporting arm is connected with the holes, and the other end is connected with wire rope and passes through the sleeve, the inner core, the sleeve holder and a bourdon tube so as to be connected with an operation handle. The device has the advantages of simple structure, firm clamping, convenient use and the like.

A system is disclosed. The system can comprise a replaceable staple cartridge comprising a plurality of staples, a proximal laterally-protruding lug, and a distal laterally-protruding lug. The system can further comprise a channel configured to receive the replaceable staple cartridge, wherein the channel comprises a sidewall comprising a proximal receptacle positioned and dimensioned to receive the proximal laterally-protruding lug and a distal receptacle positioned and dimensioned to receive the distal laterally-protruding lug.
