摘要： An OTC surgical device includes a handle having therein a compression controller and thereat an end effector, which has an electrically controlled tissue-compressor coupled to the controller and powered thereby to selectively control tissue compression. A mechanical binary-output electrical switch is disposed in-line with the compressor to place a compressing force directed upon the compressed tissue proportionally upon the switch. The switch has two switching states initiated and changed only by mechanical movement. The switch includes a biasing device retaining the switch in a first switching state until a force imparted thereupon overcomes the bias force to change to the second switching state. A switching-state-status output provides information identifying a current state and communicates with the compression controller to selectively control compression of tissue based upon the information. With appropriate feedback, the controller can keep the tissue at OTC while the surgical procedure is carried out.

摘要： A flexible endoscopic dip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

摘要： A biological forceps device for the taking of tissue samples from a body, comprising a flexible main coil attached at its distal end to a pair of homologous cast jaws. The jaws have radially arranged teeth on their distalmost end. The jaws are opened and closed by attachment to a pair of pull wires which extend through the main coil, into a handle at its proximal end, the handle has a spool which slides about a central shaft attached to the main coil. The spool is attached to the pull wires, so that movement of the spool with respect to the central shaft, effectuates a force on the proximal ends of the levered jaws, to open and close them, appropriately.

摘要： A flexible clip applier includes a flat wire wound outer tubular coil, a pair of jaws at the end of the coil, end effector wires extending through the coil and coupled to the jaws, and a clip-advancing wire extending through the coil. A large pushing force to advance a clip is created by providing a compressive force to the outer tubular coil to increase its tensile limitation, and providing a force which is compressive to the clip-advancing wire and tensile to the tubular coil while maintaining the compressive force on the tubular coil.

摘要： An endoscopic instrument has a portion having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the instrument by providing peripheral projections or fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross sectional area between the interior of the working channel and the endoscopic instrument. The resulting instrument has significantly reduced backlash while maintaining adequate fluid flow in the working channel. According to a second embodiment of the invention, a portion of the interior of the working channel of the endoscope has an interior surface having a non-circular cross sectional shape by the inclusion of a plurality of radially spaced and inwardly directed ribs or by being polygonally shaped. The resulting endoscope reduces the backlash of an endoscopic instrument inserted therein while maintaining adequate fluid flow in the working channel.

摘要： An endoscopic instrument has a control member, a portion of the member having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the control member by providing peripheral projections or fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross-sectional area between the interior of the endoscope instrument shaft and the central control member. The resulting instrument has significantly reduced backlash in end effector assembly manipulation, while maintaining adequate fluid flow in the endoscope shaft. According to a second embodiment of the invention, a portion of the interior of the shaft of the endoscopic instrument has an interior surface having a non-circular cross-sectional shape by the inclusion of a plurality of radially spaced and inwardly directed ribs or by being polygonally shaped. The resulting endoscopic instrument likewise reduces the backlash experienced in operating the distal end effector assembly.

摘要： A flexible clip applier includes a flat wire wound tubular coil, a pair of jaws at the end of the coil, end effector wires extending through the coil and coupled to the jaws, and a clip-advancing wire extending through the coil. A clip chamber is defined in the distal end of the coil. A clip pusher is provided at a distal end of the clip-advancing wire, and advances a clip into the jaws when the clip-advancing wire is moved distally. The jaws include channels in which a distalmost clip rides when the jaws are closed and the pusher is advanced, thereby causing the distalmost clip to be pushed over the tissue, and a distal anvil which operate to bend a portion of the clip to facilitate its retention on the clamped tissue. The device can push a clip with a force in excess of 1500 grams.
