摘要： A surgical instrument is provided for cutting bone and other tissue. The surgical instrument is powered by a pressurized fluid and includes a rotatable shaft connected to a dissection tool. The instrument includes a housing member comprising a one-piece base. A rotor housing chamber is defined by the base, and the rotatable shaft is located in the rotor housing chamber. A first bearing housing is defined by the base, located adjacent the rotor housing chamber, and houses a first bearing that engages the rotatable shaft. A second bearing housing is defined by the base, located on an opposite side of the rotor housing chamber from the first bearing housing, and houses a second bearing that engages the rotatable shaft. A passage is defined by the base and operable to direct a pressurized fluid through the base to the rotor housing chamber in order to rotate the rotatable shaft.

摘要： A system for use in a surgical procedure comprising a pneumatic instrument having an inlet and an outlet, a tank fluidly coupled to the inlet of the pneumatic instrument, wherein the tank provides pressurized helium gas to power the pneumatic instrument, and a compressor fluidly coupled to the outlet of the pneumatic instrument. The compressor receives the helium gas exhausted from the pneumatic instrument and compresses the exhausted helium gas to supply the tank with pressurized helium gas.

摘要： The present invention comprises a novel, lightweight, massively parallel device comprising microelectromechanical (MEMS) fluidic actuators, to reconfigure the profile, of a surface. Each microfluidic actuator comprises an independent bladder that can act as both a sensor and an actuator. A MEMS sensor, and a MEMS valve within each microfluidic actuator, operate cooperatively to monitor the fluid within each bladder, and regulate the flow of the fluid entering and exiting each bladder. When adjacently spaced in a array, microfluidic actuators can create arbitrary surface profiles in response to a change in the operating environment of the surface. In an embodiment of the invention, the profile of an airfoil is controlled by independent extension and contraction of a plurality of actuators, that operate to displace a compliant cover.

摘要： A system for performing a medical procedure comprises a first assembly and a second assembly. The first assembly comprises an articulating probe assembly and a first housing. The articulating probe assembly comprises an outer probe and an inner probe. The outer probe comprises: multiple articulating outer links and a first connector. The inner probe comprises multiple articulating inner links and a second connector. The first housing comprises: a proximal portion; a distal portion; and an opening positioned in the first housing distal portion. The articulating probe is constructed and arranged to pass through the first housing opening. The second assembly comprises: a first carriage constructed and arranged to operably engage the first connector of the outer probe; a second carriage constructed and arranged to operably engage the second connector of the inner probe; a dual linear drive assembly configured to independently translate the first carriage and the second carriage; and a second housing comprising a proximal portion and a distal portion. The first assembly is constructed and arranged to operably attach to the second assembly. Methods of performing a medical procedure are also described.
