Abstract
A tool for treating hematoma in the brain, and other tissue in the body, especially suited for use through a cannula. The tool may include a cautery probe for sealing blood vessels in the brain, and a macerating structure for disrupting a hematoma, and aspiration features for removing macerated hematoma debris from the body.
Claims12
A device for removal of body tissue, said device comprising:
- an elongate probe comprising a first tube with a distal end and a proximal end, said distal end configured for insertion into a surgical space in a patient;
- a side-facing aperture located on a side wall of the first tube near the distal end of the first tube;
- a macerator assembly comprising a rod having a proximal end and a distal end and establishing a longitudinal center line of the macerator assembly, and a macerator structure disposed at the distal end of the rod wherein
- the macerator structure is disposed within the first tube, longitudinally aligned with the side-facing aperture and rotatable within the probe and operable to disrupt body tissue proximate the side-facing aperture, wherein said macerator structure comprises a first flat blade, extending radially outwardly from the longitudinal center line, said blade having a width which closely matches an inner radius of the first tube.
