    摘要: A surgical device having a surgical element removably connected to a drive element so that drive torque is transmitted to the surgical element as the drive element rotates, while allowing the surgical element at least one degree of freedom of motion relative to the drive element; a retaining element maintains the drive and surgical elements in torque-transmitting relation during operation of the device.

    摘要: A surgical instrument includes a first member that has an opening in its distal region for admitting tissue and that is rotatable with respect to a base from which the first member extends to allow the rotational orientation of the opening to be selectively changed with respect to the axis of the instrument. A second member is disposed within the first member to transmit force to move a cutting implement disposed at its distal end and cause it to cut tissue that is exposed to the implement through the opening. In another aspect of the invention, a surgical instrument includes a rigid member that has a bend region that angularly offsets a distal region from a proximal region mounted to a first section of a base; a surgical device extending distally from a second section of the base coaxially with the rigid member carries a surgical tool distal of the bend region, and is flexible at least in the bend region to transmit force applied at a proximal end of the surgical device through the bend region to operate the surgical tool; the first base section is rotatable with respect to the second base section, allowing the relative rotational orientation between the surgical tool and the bend region to be changed.

    摘要: A surgical instrument that includes a rigid outer member within which is disposed a hollow inner member having rigid proximal and distal ends and a region disposed between the rigid proximal and distal ends that is relieved to render such region relatively flexible. The flexible region is integral with a portion of the proximal end disposed adjacent to the flexible region. The inner member transmits force (such as torsion) applied to its proximal end to move a cutting implement disposed at its distal end and cause it to cut tissue admitted through an opening in the distal region of the outer member. In another aspect, a region of the inner member is weakened (e.g., by relieving an integral region of the member) with respect to the remainder of the inner member to cause this region to break if the force (e.g., torque) applied to the inner member exceeds a predetermined threshold. In yet another aspect, the flexible region is relieved by forming openings therein, and pliable material (such as silicone rubber) is disposed in the openings.

    摘要: A method for percutaneous fixation of a pair of vertebrae of a patient, which comprises posterolaterally entering the back of a patient percutaneously with a plurality of pedicle screws, screwing each pedicle screw into the medullary canal of the pedicles of adjacent thoracic and/or lumbar vertebrae or the pedicles of the L5 and S1 vertebrae, to a position where the proximal end thereof lies adjacent the fascia of the patient; inserting pedicle screw linkages under the skin of the back of the patient and detachably securing the linkage means to the proximal ends of the screws on the same side of the spinous processes of the vertebrae to restrict relative movement between the vertebrae. A kit is provided for percutaneous fixation of vertebrae of a patient, comprising a plurality of pedicle screws of different sizes, yet of a size to enable the distal end of each screw to be screwed into the medullary canal of a pedicle of a vertebra with the proximal end thereof lying adjacent the fascia of a patient.

    摘要: An endoscope includes an insertion member rotatably mounted to a handle. A first set of optical fibers carried by the handle meets a second set of optical fibers disposed within the insertion member at a joint constructed to allow relative rotation between the sets of optical fibers about the longitudinal axis of the insertion member.

    摘要: An apparatus and method for positioning a leg during surgery has a support for holding a substantial portion of one of the patient's legs on the side facing the other leg and a pivot located in the proximity of the patient's pelvis. After patient's pelvis is secured relative to the operating table, the distal end of the support can be moved for adjustment of the outer extremity of the patient's leg relative to the operating table to selectively position the leg relative to the patient's pelvis.
