摘要:
A surgical device comprises a housing, a bioprocessing module, an end effector, and a pumping device. The bioprocessing module comprises media reservoirs, fluid conduits in communication with the reservoirs, and a port through which media is expelled. The end effector is configured for insertion into a lumen and delivering a tissue repair composition into that lumen. The end effector has at least one fluid conduit extending therethrough and at least one orifice in communication with the fluid conduit. The fluid conduit in the first end effector is in fluid communication with the port on the bioprocessing module. The pumping device is operable to urge a tissue repair composition comprising at least a portion of the contents of the media reservoirs through the fluid conduit of the first end effector such that the tissue repair composition is expelled from the at least one orifice.

Various forms of surgical instruments are disclosed. In various embodiments, an end effector having operable and closable jaws is attached to a distal end of an elongate shaft such that portions of the jaws are axially offset from the elongate shaft. Other jaw embodiments are coupled to an actuation arrangement that permits portions of the jaws to be moved out of axial alignment with the elongate shaft. Other jaw embodiments are configured to facilitate tissue dissection. Electrosurgical instruments are also disclosed. One embodiment employs a flexible electrode that is conformable to tissue.

Various embodiments are directed to a surgical instrument comprising, a shaft, and an end effector. The shaft may be coupled to the handle and may extend distally along a longitudinal axis. The end effector may be positioned at a distal end of the shaft and may comprise first and second jaw members and a reciprocating member. The first and second jaw members may define first and second longitudinal slots. One or both of the jaw members may be pivotable relative to the other about a pivot point. The reciprocating member may be translatable distally and proximally parallel to the longitudinal axis and through the first and second longitudinal slots. A distal portion of the reciprocating member may define a blade. The instrument may comprise an overtube translatable distally to exert a force on a portions of the first and second jaw members tending to close the first and second jaw members.

A surgical instrument that has an actuation system that is configured to generate at least two separate actuation motions. A clutch assembly is movable between an engaged position wherein the clutch assembly is in operable engagement with the actuation system and an unengaged position. In various forms, the surgical instrument includes a manually actuatable trigger assembly that interfaces with the clutch assembly and the actuation system such that a first stroke of the trigger assembly causes the actuation system to generate a first one of the actuation motions and moves the clutch assembly from the unengaged position to the engaged position whereupon a second stroke of the trigger assembly causes the actuation system to generate another one of the actuation motions.

A surgical instrument that has an articulatable end effector. The instrument includes an articulation system that has a rotatable actuator member that interfaces with an articulation transmission. Rotation of the actuator member in a first rotary direction about an actuation axis causes at least one articulation member to articulate the surgical end effector in a first articulation direction and rotation of the actuator member in a second rotary direction causes at least one articulation member to articulate the surgical end effector in a second articulation direction.

In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that rotatably supports an ultrasonic transducer assembly therein that may be selectively rotated by a motor housed therein. Various forms of blades are disclosed for attachment to the ultrasonic transducer assembly such that the blade may be selectively rotatable within a hollow outer sheath. The hollow outer sheath has at least one opening therein through which the blade tip may be exposed to tissue. Vacuum may be applied to the cutting implement or through the outer sheath to draw tissue through the opening(s) in the sheath and into contact with a portion of the blade.
