摘要： 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 comprising an operative assembly of at least two subcomponents, which together provide a nozzle are provided. In certain embodiments, the at least two sub-components may comprise a nozzle-providing component, such as a nozzle ring, and a holder that is configured to retain and position the nozzle-providing component in the nozzle assembly. In certain embodiments, the nozzle-providing component can comprise a liquid flow passage having a diameter that continuously decreases along at least a portion of its length.

摘要： The present invention provides a series of devices for performing surgical procedures utilizing electrodes for performing electrocautery on a tissue of the body of a patient. The invention includes, in one aspect, a series of devices comprising surgical instruments providing at least one electrode for performing electrocautery, and, in another aspect, provides a method for cutting and cauterizing tissue with a surgical instrument. In yet another aspect, the invention involves a method for detecting the location of a bleeding vessel in a liquid-filled, visually monitored surgical field of a patient and for electrocauterizing the vessel to stop the bleeding before visualization of the surgical field is compromised. Preferred surgical instruments according to the invention also include operable components for forming a liquid cutting jet for cutting or ablating tissue of a patient and/or for providing a rotating, tissue contacting component for cutting, grinding, ablating, etc. tissue during a surgical procedure. Some surgical instruments, according to the invention, include one or more liquid conducting lumen therein for transporting and/or removing a liquid from a surgical operating field, which lumen, in some cases, are selectively coated with a layer of an electrically insulating material so that certain, selected, uncoated regions of an external surface of the lumen can act as an electrocautery electrode of the instrument.

摘要： An instrument for delivering a variable pressure stream of fluid as a coherent jet. The instrument may be configured for holding in the hand of a user or for manipulation by machine control. The orifices may be oriented axially, transversely or obliquely. A deflector may be provided opposite the orifice to transform the jet stream into a harmless spray. The deflector may be slidable (in the axial mode) or pivotable (in the transverse mode) to ensure a small instrument profile. The instrument may be moldable allowing the user to reshape the jet tip into a desired configuration. The instrument may be remotely steerable and enable a user to selectively alter the direction of the jet without having to remove the instrument from the surgical site.
