Surgical devices
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.
