    摘要： A bone fixation device is provided with an elongate body having a longitudinal axis and having a first state in which at least a portion of the body is flexible and a second state in which the body is generally rigid, an actuateable gripper disposed at one or more locations on the elongated body, a hub located on a proximal end of the elongated body, and an actuator operably connected to the gripper(s) to deploy the gripper(s) from a retracted configuration to an expanded configuration. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a hub on another side of the fracture, and operating an actuator to deploy at least one gripper of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Alternative gripper designs are disclosed that may be used in various combinations.

    摘要： A surgical irrigation system is suitable for endoscopic and other surgical procedures. A hand held handpiece has a forward protruding hollow tip for supplying irrigation liquid to a surgical site, a hand actuable control for controlling irrigation liquid flow to the tip, and an irrigation liquid inlet. A self contained pumping unit is locatable adjacent a source of irrigation liquid and remote from the handpiece. The pumping unit comprises a housing containing an outlet for irrigation liquid, a pumping member for pumping irrigation liquid through the outlet, a motor for driving the pumping member, and an electric battery assembly for energizing the motor. An elongate tube connects the pumping outlet to the handpiece irrigation liquid inlet for supplying pumped irrigation liquid to the handpiece.

    摘要： An bipolar electrosurgical tool (10) for cauterizing or ablating tissue. The tool has a nose cone (12) which serves as a handle. A conductive shaft (14) extends from the nose cone. A tip assembly (18) with an active electrode (20) is mounted to the shaft. A circuit board (78) is mounted in the nose cone. Conductive traces that forming contact pads (96, 102) are formed on the circuit board. A web (108) formed from a single piece of elastomeric material is seated over the opening in which the printed circuit board is mounted to seal the opening shut. Integrally formed with the web are buttons (116, 118) that are in registration over the contact pads. The buttons can be depressed downwardly towards the contact pads. When a button is so depressed, a conductive landing pad (120) integral with the button closes the connection between the traces that form the contact pad. Thus, the tool of this invention is provided with switches. The circuit board also has two conductive traces (92, 104a) that run in parallel. If there is a leak into the nose cone, a connection is established across these traces and shorts out a resistor (105). The shorting out of this resistor provides a control console (22) with an indication that there is a leak. The electrode is formed from a single piece of tantalum. The electrode has a head formed with a hole (172) trough which fluid flows. The electrode is seated in a sleeve (136b) provided with a through bore (177) in registration with the electrode hole.
