    摘要： An electrically operated surgical instrument includes a surgical end effector having an actuation assembly effecting a surgical procedure when actuated and a handle connected to the end effector for actuating the assembly. A part of the assembly moves between start and fully actuated positions. The handle has a self-contained power supply and a drive assembly disposed entirely within the handle. The drive assembly has an electrically powered motor and a controller electrically connected to the power supply and to the motor. The controller selectively operates the motor. A transmission mechanically connects the motor to the moving part and selectively displaces the moving part anywhere between the start and fully extended positions when the motor is operated. A manual release is mechanically coupled to the transmission to selectively interrupt the transmission and, during interruption, displaces the moving part towards the start position independent of motor operation.

    摘要： A method and device for treating a Chronic Total Occlusion provides a controllable stiffness catheter with a shaft having a stiffness sheath and an access lumen. The device has a stiffness device in a stiff state below a given temperature and in a soft state above the temperature, a temperature-changing device in thermal contact with the stiffness device, the temperature-changing device changing a temperature of the stiffness device below and above the temperature, and a power controller electrically connected to the stiffness device and selectively supplying power to the temperature-changing device to change a stiffness of the stiffness device between the stiff and soft states. A guidewire is moved to a treatment site and the catheter moves along the guidewire up to CTO in its soft state. The catheter stiffens without straightening and, in the stiff state, the catheter or the guidewire is projecting through the CTO.

    摘要： A medical device includes a surgical end effector, an end effector control handle, and a control shaft having a longitudinal axis and a handle portion connecting the control shaft to the control handle rotatably about the longitudinal axis. A passive articulation joint connects the end effector to the control shaft. An articulation joint release unlocks the articulation joint when actuated and locks the articulation joint when unactuated. An end effector control device is rotationally fixedly connected to at least a portion of the control shaft to correspondingly rotate the control shaft about the longitudinal axis when the control device is rotated and is longitudinally connected to the joint release to selectively unlock the articulation joint when actuated.

    摘要： A flexible endoscopic clip 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： An electrocautery surgical device includes a battery power source and radio-frequency signal generating circuitry electrically coupled to the battery power source and operable to deliver power to an electrosurgical forceps. The radio-frequency signal generating circuitry includes a transformer having a primary winding and a secondary winding. The primary winding includes first and second primary sub-windings. At least one switching component is electrically coupled to the first and second primary sub-windings and is operable to switch between engaging the first primary sub-winding and engaging the second primary sub-winding such that a current flows through the first and/or second primary sub-windings. The first and second primary sub-windings have a different number of turns such that the radio-frequency signal generating circuitry produces a different impedance value depending on which one of the first and second primary sub-windings is engaged.

    摘要： A surgical clip has a base portion and two generally parallel, spaced arms extending from the base portion and defining an opening therebetween. The arms terminate distally in fingers which are of reduced width and thickness relative to the arms and which are adapted to be bent towards and past each other. A transition section from each arm to the finger provides curved structures which extending away from each other and providing a wider mouth for the opening between the arms. The arms also have a proximal section with an undercut which helps in flexure of the arms. The base is an extended structure having a rounded proximal end with outwardly extending shoulders which are arranged to be engaged by the curved structures of the mouth of another clip.
