Abstract

A tool has a handle and an elongate shaft that extends distally from the handle. A distal portion of the shaft is inserted into a subject during a surgical procedure. An optical fiber delivers laser energy to a tip at the distal portion of the shaft. The tip includes a mechanical cutting mechanism including a moving part that absorbs the laser energy, thermally conducts the absorbed energy to tissue that is disposed between the moving part and another part, and moves with respect to the other part in order to cut tissue that is disposed between the parts using a mechanical force that is lower than a mechanical force that would be required to cut the tissue in the absence of the laser energy. Other embodiments are also described.
