摘要： Certain embodiments of the surgical instruments provided according to the invention utilize a channel positioned adjacent to and downstream of a liquid jet-forming nozzle such that at least a portion of the liquid jet passes at least one of within the channel and adjacent to and along the length of at least a portion of a longitudinally-oriented opening in the channel, when the instrument is in operation. The use of such channels in certain embodiments of the inventive surgical instruments can enable the instruments to provide enhanced control over the depth and degree of cutting and/or ablation of tissue; and/or can provide improved and enhanced functionality for cleaning, debriding, and/or trimming and cutting a tissue/surface; and/or can provide longer effective liquid jet beam cutting/ablation lengths by reducing the degree of dispersion of the jet along its length.

摘要： The invention provides a variety of surgical instruments for forming a liquid jet, which are useful for performing a wide variety of surgical procedures. In some embodiments, the invention provides surgical liquid jet instruments having a pressure lumen and an evacuation lumen, where the pressure lumen includes at least one nozzle for forming a liquid jet and where the evacuation lumen includes a jet-receiving opening for receiving the liquid jet when the instrument is in operation. In some embodiments, the pressure lumen and the evacuation lumen of the surgical liquid jet instruments are constructed and positionable relative to each other so that the liquid comprising the liquid jet, and any tissue or material entrained by the liquid jet can be evacuated through the evacuation lumen without the need for an external source of suction. The invention also provides a variety of surgical liquid jet instruments that are constructed and configured specifically for use in a surrounding liquid environment or a surrounding gaseous environment. The invention also provides a variety of surgical liquid jet instruments that are rotatably deployable from an undeployed position, for insertion into the body of a patient, to a deployed position, in which there is a separation distance between the liquid jet nozzle and the jet-receiving opening that defines a liquid jet path length. The invention also provides surgical methods utilizing the inventive surgical liquid jet instruments, and methods for forming components of the surgical liquid jet instruments.

摘要： Systems, apparatus and methods for removing tissue of various densities from a surgical site in a minimally invasive manner are provided. The invention may include a fine stream of sterile saline, coupled with a suction effect to cut and remove tissue. A power console may be coupled with a handpiece. The power console may utilize an electric motor, thereby transmitting pressurized sterile saline through a high-pressure tube. The distal end may deliver the saline across a window as a high velocity jet stream which, when coupled with the pressure gradient, pulls and then cuts the target tissue into the cutting window and removes it. The tissue and waste saline may then travel down an evacuation lumen to a waste container. By adjusting pressures, tissue types of various densities may be debrided while minimizing disturbance of surrounding tissue.

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： Pumping cartridges useful for medical and surgical pumping and infusion procedures are disclosed. Methods for manufacturing and utilizing such pumping cartridges and methods for pumping or infusing liquids for delivery to the body of a patient or a surgical or medical instrument for performing a medical treatment are also described. The invention includes, in one aspect, a series of pumping cartridges comprising cylinders and pistons constructed and arranged for sliding or reciprocating motion within the cylinders. The pistons and/or cylinders can comprise a sealing component including a circumferential, flared sealing flange and can be configured to enable the pumping cartridge to generate high liquid pumping pressures, for example above 1,000 psig. Many of the pumping cartridges disclosed can be relatively easily manufactured at a low cost per unit and can be configured to be detachable from a pump drive unit and disposable after a single use. Various compact flow path configurations are provided in the several pumping cartridge embodiments described, including a Y-shaped configuration, a T-shaped configuration, and an axial configuration. Some pumping cartridges disclosed include pistons including or at least partially forming a valve and/or pistons that are relatively movable with respect to a piston rod to which they are connected. Valve including a valve seat and a movable sealing element able to create a seal capable of withstanding differences in fluid pressures thereacross of at least about 1,000 psi, and in some cases up to in excess of 10,000 psi, without substantial fluid leakage therethrough are disclosed. In some of the disclosed valves, the movable sealing element is concave in shape, and can be curved, to create a mechanical advantage for improved sealing performance. Methods for manufacturing axially-configured pumping cartridges from thin-walled tubing are also disclosed, as well as a series of methods for pumping or infusing a liquid for delivery to the body of a patient or a surgical or medical instrument for performing a medical treatment using the above-mentioned pumping cartridges and devices.
