摘要： A method and apparatus are provided for quickly connecting a handpiece to a pressurized fluid source. A hollow tube on the handpiece is inserted through an aperture in an annular gasket which is held in a chamber in a body. On application of pressurized fluid to the body, the gasket is pressed against the walls of the chamber, and against the tube, thereby channeling the pressurized fluid through the hollow tube. The handpiece is retained in connection with the body by a releasable connector, such as a latch. The handpiece can be removed and replaced by releasing and remaking the connection.

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： Certain embodiments of the invention provide a variety of methods of manufacturing a liquid jet-forming surgical instrument. According to these methods, a nozzle assembly of the instrument is electroformed on a mandrel. The nozzle assembly includes a nozzle providing a jet-opening, wherein the nozzle is shaped to form a liquid jet. In some embodiments, the mandrel includes a first mandrel portion and a second mandrel portion. Once the nozzle assembly is formed, the mandrel may be removed from the nozzle assembly. The nozzle assembly may in certain embodiments be coupled to an outlet of the pressure tube. In certain embodiments, an inlet of an evacuation tube is positioned such that a jet-receiving opening of the evacuation tube is positioned opposite the jet-opening of the nozzle.

摘要： A device for treating a spine includes a proximal component positioned partially or entirely within a first vertebra and a distal component positioned partially or entirely within a second vertebra and may also include an intermediate component. A method for treating a spine includes forming a curved channel that extends through a first vertebra from a pedicle to an endplate, and advancing the components through the curved channel, the orientation of the proximal component relative to the distal component changing by at least 40 degrees while the proximal component passes through the curved channel. In another aspect, a method for treating a spine includes forming a curved channel that has a pedicle region, a central region, and an endplate region, where the channel diameter for the central region is larger than the channel diameter for the pedicle region or the endplate region, and advancing an implant through the channel.
