    摘要: Various mechanisms, and a method of operating them, are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by means of the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation. In the first angular orientation, the fastener advancing member is restrained against longitudinal movement to assist in installation of the cartridge onto the instrument. The distal end of the instrument can be articulated, and a helical gear operator is provided for effecting the articulation. The helical gear pitch decreases in a direction such that the mechanical advantage is increased as the articulation angle increases.

    摘要: A printed circuit board interconnect assembly for use in an automobile comprising a male portion and a female portion. The female portion of the interconnect assembly contains crimped spring clip terminals inside a plastic housing. The male portion of the interconnect assembly contains male pins held together by a plastic housing. The male pins are angled at their mating ends to engage and be retained by the female spring clip terminals.

    摘要: A method for medical treatment includes beginning coagulating patient tissue using an energy-based clamp coagulator, determining the clamping force, and measuring the acoustic impedance of the patient tissue. The method also includes compensating the measured acoustic impedance for clamp pressure and monitoring the coagulation using at least the compensated measured acoustic impedance. A first medical treatment system includes an energy-based clamp coagulator, an acoustic-impedance measurer, and a force measurer. A second system includes an energy-based clamp coagulator having a clamping member which includes, or is adapted to function as, an electrical-impedance-measuring electrode for measuring an electrical impedance of the clamped patient tissue. A third system includes an energy-based clamp coagulator having a clamping member which includes, or is adapted to function as, a temperature sensor for measuring a temperature of the clamped patient tissue.

    摘要: Various mechanisms are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation. In the first angular orientation, the fastener advancing member is restrained against longitudinal movement to assist in installation of the cartridge onto the instrument.
