Abstract
A surgical device for use in removing a lesion from a brain includes a first tube, a second tube disposed within the first tube, a sleeve that encloses a portion of the first tube, wire loops attached to a distal end of the first tube, a loop expander and rotation mechanism drivingly coupled with the wire loops, an aspiration port, and an irrigation port. The loop expander and rotation mechanism is operable to expand the wire loops while rotating the wire loops relative to the first tube and contract the wire loops while rotating the wire loops relative to the first tube. Cut tissue is aspirated via the aspiration port. Irrigation fluid is supplied to irrigate the cut tissue via the irrigation port.
Claims20
A brain probe device for use in removing a lesion from a brain of a patient, the brain probe device comprising:
- a first tube having a first tube lumen and first tube tissue removal openings;
- a second tube disposed within the first tube and having a second tube lumen and second tube radial openings configured to cooperate with the first tube tissue removal openings to cut tissue and allow aspiration of the cut tissue through the second tube lumen via the first tube tissue removal openings and the second tube radial openings;
- a probe sleeve having a proximal portion that encloses a portion of the first tube;
- wire loops attached to a distal end of the first tube and configured to be outwardly expanded from the first tube and rotated relative to the first tube to cut the tissue;
- a loop expander and rotation mechanism comprising an elevator member that is drivingly coupled with proximal ends of the wire loops, the loop expander and rotation mechanism being operable to:
- simultaneously rotate and translate the elevator member relative to the first tube to simultaneously expand the wire loops and rotate the wire loops relative to the first tube;
- and
- simultaneously rotate and translate the elevator member relative to the first tube to simultaneously contract the wire loops and rotate the wire loops relative to the first tube;
- an aspiration port in fluid communication with the second tube lumen for aspiration of the cut tissue;
- and
- an irrigation port for transferring irrigation fluid to irrigate the cut tissue in synchrony with aspiration of the cut tissue.
