A support system includes a headwear system, a frame adapted to have a visor attached thereto, a first member attached to the headwear system, a second member attached to the frame, which is pivotable relative to the first member, an adjustable mechanism adapted to abut and apply force to the second member in a first state to compress the second member into abutting engagement with the first member, an extending pivot member extending axially through a passage in the first member and a passage in the second member. The position of the adjustable mechanism is adjustable to place it in the first state or in at least a second, nonabutting state. The extending pivot member includes a first flange and a second flange, spaced from the first flange to capture a portion of the first member and a portion of the second member therebetween.

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.

An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue thereby causing current to flow through the tissue and, as a result, generate heat within the tissue. The surgical instrument can further comprise a fluid circulatory system embedded within at least a portion the end effector wherein, in at least one embodiment, the fluid can be dispensed from the fluid circulatory system and onto the jaws of the end effector and/or the tissue positioned between the jaws.

An ultrasonic surgical instrument that supports an ultrasonically excited blade and an outer sheath that can be selectively rotated relative to each other to bring a distal cutting tip of the blade into contact with at least one cutting surface formed on a distal end of the outer sheath. In some embodiments, the distal cutting tip may contact two cutting surfaces located on opposing sides of an opening in the outer sheath through which the distal cutting tip protrudes. Tissue pads may be attached to the cutting surfaces. Various embodiments also include at least one suction lumen.
