Abstract
Disclosed are nozzles and nozzle assemblies of liquid jet-forming surgical instruments, surgical instruments employing such nozzles and/or nozzle assemblies, and methods of fabricating the nozzle assemblies in forming surgical instruments. Also, disclosed are liquid jet-forming surgical instruments including both liquid jet-forming nozzles and optional evacuation lumens, which when provided can be configured to receive the liquid jet and evacuate the liquid forming the liquid jet. Certain embodiments of such surgical instruments include inventive nozzle alignment component(s) to facilitate alignment of the nozzles and evacuation lumen upon assembly. In certain embodiments, surgical instruments are provided that include a nozzle that is shaped to form a liquid jet, which has surfaces that are optically smooth. In certain embodiments, the nozzle has a configuration enabling the nozzle to form a liquid jet that has the ability to remain collimated over longer distances than is typically achievable with conventional liquid jet surgical instrument nozzles having the same ratio of nozzle length to minimum inner diameter of the jet opening. In certain embodiments, nozzle assemblies compri…
