    摘要： Arthroscopy hook-clippers comprise a circular cross-section outer shaft having at a distal end thereof a fixed jaw and a movable jaw pivoted to the fixed jaw. Within the shaft are a thrust rod which is movable axially thereof to pivot the movable jaw with respect to the fixed jaw, and beside the thrust rod, a vacuum extraction channel. The extraction channel is of substantially circular cross-section excepting that it has a flat upper wall, which co-operates with the upper internal wall of the shaft to define a guideway for the thrust rod the cross-section of which is matched to that of the guideway.

    摘要： An endoprosthesis which comprises a flexible, collapsible, hollow device which can be filled after it is positioned within the bone structure. In the case of a prosthesis designed to replace the ball of the femur, the endoprosthesis has a ball portion, a neck portion attached to and communicating with the ball portion, a body portion attached to and communicating with the neck portion, and an access opening opposite the ball portion. A method for installing the endoprosthesis in the hip is also described, in which a portal is drilled through the lateral cortex of the femur at a location opposite the ball, the ball of the femur is removed, and the endoprosthesis is inserted through the portal. Finally, the invention provides a special tool that can be used for removing the ball of the femur through a portal in the lateral cortex without dislocating the hip. Generally, this tool comprises a rotatable shaft, a cutting blade received in an end portion of the shaft, and being hinged at its lower end, and means for extendig and retracting the blade.

    摘要： A forceps and in particular hooked shears, has a distal extremity of the forceps shaft provided with a recess of the one fixed branch of the forceps jaws, with which branch there co-operates a double-armed pivotally displaceable jaw branch by means of a scissors grip and a push and pull rod. The recess of the fixed jaw branch is continued by a shaft slot whereof the delimiting edge forms a stop for a stepped surface of the push and pull rod placed in impingement in the closed position of the jaws and the open position of the jaws is restricted by impingement of a surface of the pivotable jaw branch against the top distal edge of the push rod.

    摘要： Cutting-suctioning instrument having an elongated support and first and second, opposed distal jaws, at least one of which is pivotable about a transverse axis and adapted to be closed by an actuator, and a suction throat defined between proximal portions of the two jaws. Preferably, a sliding inner tube, which defines the suction passage, serves as actuator to move the pivotable jaw. As a cutter for meniscal cartilage, a hollow tube defining a tissue-fragment transport, suction passage is arranged to communicate through the open throat with the region between the jaws to receive cut tissue while suction is associated with the proximal end of the instrument for enabling tissue to be drawn from between the jaws, through the throat and thence through the transport passage while the instrument remains in situ for repeated cutting. Preferred embodiments of the instrument are especially useful in arthroscopic surgery.

    摘要： A vacuum sleeve is disclosed for removing severed tissue from a surgical site. The vacuum sleeve is used in conjunction with a surgical appliance having a cutting element and the vacuum sleeve is connected to a vacuum source. The vacuum sleeve includes an elongated body member having a distal and a proximal end. The body member defines an internal passageway which extends between the distal and proximal ends of the body member. The internal passageway removably receives therein the surgical appliance and the distal end of the body member defines a aperture such that when the surgical appliance is disposed within the internal passageway, the cutting element of the surfical appliance extends through the aperture thereby enabling the cutting element to sever tissue from the surgical site. The internal passageway is connected to a vacuum source such that in use of the surgical appliance, when tissue is severed from the surgical site, the severed tissue is drawn from the surgical site through the aperture and along the internal passageway towards the source of vacuum.

    摘要： A surgical instrument in the form of a power driven rongeur which includes an air turbine motor adapted to control the closing and opening of the cutting blades. A toggle linkage connects the cutting blades to a threaded member which linearly advances and retracts upon rotation of the air motor so as to cause the opening and closing of the cutting blades respectively.
