A surgical instrument is inserted through a guide tube. A telemanipulation system moves the distal end of the surgical instrument in all six Cartesian degrees of freedom independently of any guide tube movements.

A surgical instrument includes a housing that supports an elongated shaft. A selectively movable drive rod extends through the elongated shaft and carries a cam pin in a longitudinal direction. An end effector for surgically treating tissue is supported by the elongated shaft and includes upper and lower jaw members pivotally coupled to one another about a pivot axis. The upper jaw member includes a first pair of laterally spaced flanges, and the lower jaw member includes a second pair of laterally spaced flanges defining a camming slot for engaging the cam pin. The flanges are arranged in an offset configuration where one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

The safety sheet of the present invention may include a bed sheet with sleeves along one or more sides. The sleeves may be continuous or slotted and may accommodate inserts constructed of a material soft enough to avoid injury yet sturdy enough to provide an effective barrier to lateral motion of a bed's occupant. The safety sheet may include solid or hollow inserts. Portability of the safety sheet may be maximized by the use of inflatable / deflatable inserts. Inserts may vary in size and shape, and the sleeves may vary in size to accommodate a range of insert sizes. Alternatively, the sleeves may be stuffed with soft materials such as socks or other clothing when inserts are unavailable. The safety sheet may be reversed with inserts in place for aesthetic and comfort purposes or without inserts to hide the sleeves when inserts are no longer needed.

An endoscope for an optical fiber provides for inflow and outflow of irrigant. A telescope is included having a field of view directed into a working region. The endoscope defines a “hooded region” with an extended, blunt tip. The optical fiber fits within the endoscope has a side or end firing tip with an emission surface. A guide element is adapted to movably support the optical fiber in a position spaced away from the working region, and limit lateral movement of the tip without preventing longitudinal and rotational movement. An irrigant flow arrangement operates to direct inflowing irrigant over the emission surface of the tip. The fiber is assembled with a fiber coupler, a handle, a fiber port cap, and a travel limiter fixed to the fiber at a predetermined distance from the tip. The travel limiter cooperates with the endoscope and the fiber port cap to limit longitudinal and rotational movement of the fiber.

A first cushion receiving member of a seat cushion and a second cushion receiving member of a seat back are turnably connected to each other by a connecting member. The first cushion receiving member is turnably supported at its front end on a front frame of a first framework. The second cushion receiving member is supported on a second framework, through a spring fixed at its upper portion at at least two points and at its lower portion to the second framework and through an elastic fabric having a periphery fixed to the second framework. Thus, the first and second cushion receiving members can be prevented from being oscillated laterally, and the vibration caused by the expansion and contraction of the spring can be dampened by the elastic fabric. As a result, it is possible to permit the longitudinal and vertical movement of the first and second cushion receiving members for supporting the cushion members of the seat and to restrict the lateral movement of the cushion receiving members, and to thereby prevent uncomfortable lateral oscillation of an occupant's body so as to improve sitting comfort.
