Abstract
A method and apparatus for manipulating a surgical guidewire. The apparatus comprises a chuck for selectively coupling motive force to a surgical guidewire and an actuator, coupled to the chuck, for imparting an axial motive force to the chuck. Embodiments of the invention further comprise a method of using the apparatus.
Claims12
Apparatus for manipulating a surgical guidewire used in surgery comprising:
- a chuck, the chuck selectively coupling motive force to a surgical guidewire;
- an actuator, coupled to the chuck, for imparting linear motive force and rotary motive force to the chuck;
- wherein the chuck comprises:
- a coupler for receiving the motive force from the actuator;
- a hub coupled to the coupler;
- and
- a wedge positioned within a window in the coupler and retained in the window by the hub, the wedge having an angled surface that interacts with the hub to move the wedge between a guidewire locked position and a guidewire unlocked position;
- an axle coupled with the chuck and the actuator, the axle having an axially extending passage which is configured to allow the surgical guidewire to slidably extend therethrough;
- and
- a housing that houses the actuator and axle and is sized to fit in a palm of a user, wherein the chuck imparts a linear movement and a rotary movement to the surgical guidewire.

Apparatus for manipulating a surgical guidewire used in surgery comprising:
- a chuck for selectively coupling motive force to a surgical guidewire, where the chuck comprises:
- a coupler;
- a hub coupled to the coupler and having a dimpled surface for interacting with a protrusion;
- and
- a wedge positioned within a window in the coupler and retained in the window by the hub, the wedge having an angled surface that interacts with the hub to move the wedge between a guidewire locked position and a guidewire unlocked position;
- and
- an actuator, coupled to the chuck, for imparting rotary motive force to the coupler, where the actuator imparts rotary motive force to the coupler and the dimpled surface of the hub interacting with the protrusion produces linear motive force upon the chuck, wherein the chuck imparts a linear movement to the guidewire.
