A coating assembly for coating jaws of an electrosurgical instrument includes a dispensing device and a jaw applicator. The dispensing device has a non-stick coating material contained therein and includes a discharge port. The jaw applicator includes an applicator body defining a cavity therein. The applicator body includes a first wall and a second wall disposed in spaced relation relative to each other and the cavity extends therebetween. Each of the first and second walls has openings defined therethrough that are in open communication with the cavity. The discharge port of the dispensing device is configured to engage the jaw applicator in a fluid tight manner to define a flow path for the non-stick coating material that extends out of the discharge port, into the cavity of the applicator body, and out of the openings defined in the first and second walls.

A mesh deployment device is configured to place a surgical mesh on tissue retro muscularly. In particular, the mesh deployment device includes an arm assembly that is transitionable between a retracted configuration, in which, stationary and covering arms are in superposed relation such that the surgical mesh is supported by the supporting arm therebetween, and a deployed configuration, in which, the stationary, covering, and supporting arms are circumferentially spaced apart to support the surgical mesh thereon.

Surgical mesh deployment device

A surgical instrument including a housing, an elongated portion, an end effector, and an illumination mechanism. The end effector is disposed adjacent a distal portion of the elongated portion and is configured to manipulate tissue. The illumination mechanism includes an actuator, at least one light, and at least one elongated light rod. The actuator is disposed in operative engagement with the housing. The at least one light includes a shell and is disposed adjacent a distal portion of the elongated portion. The at least one elongated light rod is disposed in mechanical cooperation with the actuator and with the at least one light. The at least one light is movable from a first position where a portion of the shell is flush with the outer wall of the elongated portion to a second position where the portion of the shell is disposed at an angle relative to the outer wall of the elongated portion.

A stapling device includes first and second jaws. The second jaw defines first and second threaded bores. A drive member has a distal end portion supporting a rack. An approximation drive assembly includes a first lead screw received within the first threaded bore. A second lead screw is received within the second threaded bore. A first pinion is supported on the first lead screw. A second pinion is supported on the second lead screw. Moving the drive member from the retracted position toward the advanced position advances the rack to rotate the first pinion and the second pinion, the first lead screw within the first threaded bore, and the second lead screw within the second threaded bore to move the second jaw in relation to the first jaw from an open position to a clamped position.

Stapling device with continuously parallel jaws

A surgical device, or a portion of a surgical device, that places purse string sutures in tissue within a body (e.g., intra-peritoneal space). The surgical device includes, or an end effector for a surgical device includes, a jaw assembly, staple cartridges, and a suture.

Laparoscopic purse string suture 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.

Surgical stapling device with parallel jaw closure

A surgical stapling device includes a tool assembly having an anvil assembly and a cartridge assembly. The anvil assembly includes a staple deforming surface and defines an elongate channel that supports a roller. The staple deforming surface defines a transverse slot. The roller supports a buttress material that can be pulled through the transverse slot to position the buttress material atop the staple forming surface.
