LASER BLADE PULSED LASER ABLATION

Abstract

A device for resecting hard biological tissue is provided. The device comprises a laser source configured to emit a laser beam, and a plurality of optical fibers, each having a proximal end optically coupled to the laser source and a distal end configured to emit the laser beam. A support structure maintains the distal ends of the optical fibers in a predetermined spatial arrangement. A window is positioned to permit transmission of the laser beam from the distal ends toward the tissue. At least one spacing element is associated with the support structure to maintain a predetermined distance between the distal ends and the tissue during operation. The device further includes a fluid delivery system associated with the support structure and configured to deliver a fluid to a cutting interface at the tissue. The arrangement enables precise, efficient, and controlled laser ablation or resection of hard tissue, with improved cooling and debris management.
