Abstract
A torque device employs a cylindrical housing surrounding a guidewire to provide concentric loading of the guidewire along a central axis of the housing attachable at any point along a length of the guidewire. Improved torsion of the guidewire is obtained by clamping the guidewire so that it runs along the center axis of the housing offering intuitive rotational handling (torque) of the guidewire along the torque axis.
Claims20
A device for manipulating a guidewire for surgery comprising:
- a housing adapted to receive a wire partially insertable into a patient at an incision site, the housing having a slot receiving a center portion of the wire between a proximal end and distal end of the wire wherein the wire is positionable to extend on a central axis of the housing;
- the housing supporting
- a clamp assembly having a pincher and a biasing member configured to apply a biasing force on the pincher to bias the pincher to contact the wire at an at least one discrete pinch area to prevent movement of the wire with respect to the pincher.
A method for manipulating a guidewire having a central portion between a proximal end and distal end of the guidewire for surgery comprising:
- inserting the proximal end of the guidewire into a patient at an incision site,
- inserting the central portion of the guidewire into a slot of a housing wherein the guidewire is positionable to extend on a center axis of the housing;
- and
- clamping a clamp assembly to contact the guidewire at an at least one discrete pinch area.
