    摘要： A surgical alignment device is disclosed that is controlled remotely through the use of an actuator, where the actuator in turn controls at least one local adjustment device. The alignment device is suited for neurosurgery, although it is not exclusively limited to neurosurgery. The alignment device includes an insertion guide that is coupled to the local adjustment device, the insertion guide being used to guide a device such as a catheter into a patient. The alignment device may also be coupled to a control module such as a microcomputer that controls the orientation of the insertion guide in response to inputs from the surgeon as to a location of interest within the patient.

    摘要： A method and apparatus accurately maintains alignment of a surgical instrument. The apparatus includes a base with an attached movable member. The movable member includes a passage forming a portion of a trajectory path. A relaxable or rigid material has a similar passage in common with the passage of the movable member. If a relaxable material is used, the passage portion of the relaxable region is held open by an inserted stem removably attached to the movable member. The instrument is then inserted into the center of the stem and thus into the trajectory path. The stem is removed by withdrawing it from the movable member over the proximal portion of the instrument. This releases the relaxable region to tightly hold the instrument in place. Alternatively, using a relaxable or rigid component, the component is slid laterally to at least partially offset a passage through the component from the passage of the movable member to reduce a combined effective area of the passages and to grasp an instrument.

    摘要： A trajectory guide assembly that guides an instrument relative to a patient includes a mounting seat configured to be supported by the patient. The assembly also includes a trajectory member moveably supported by the mounting seat. The trajectory member defines a trajectory passage. Also, the assembly includes a cap member moveably supported by the trajectory member. The cap member defines a cap opening, and the cap member is selectively moveable to a first position relative to the trajectory member to retain the instrument in both the cap opening and the trajectory passage. Additionally, the cap member is selectively moveable to a second position relative to the trajectory member to release the instrument.

    摘要： An orientation-independent hydraulic system comprises a dynamic fluid reservoir defining a first volume substantially equal to the volume of the fluid therein, and a hydraulic cylinder in fluid communication with the dynamic fluid reservoir. The hydraulic cylinder has a second volume of hydraulic fluid and a piston rod configured to extend and retract in response to changes in the second volume. A first hydraulic pump is configured to pump hydraulic fluid between the hydraulic cylinder and the dynamic fluid reservoir, thereby moving the piston rod between the extended and retracted positions.
