International Classification:

A61B 1804

US Classification:

606 34, 606 40, 606 49, 606 50

Abstract:

An bipolar electrosurgical tool ( ) for cauterizing or ablating tissue. The tool has a nose cone ( ) which serves as a handle. A conductive shaft ( ) extends from the nose cone. A tip assembly ( ) with an active electrode ( ) is mounted to the shaft. A circuit board ( ) is mounted in the nose cone. Conductive traces that forming contact pads ( ) are formed on the circuit board. A web ( ) 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 ( ) 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 ( ) 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.

International Classification:

A61M 100

US Classification:

604 31, 604 67

Abstract:

A fluid management pump system ( ) for applying an irrigation/distention solution to a surgical site. The system includes a pump ( ) for forcing the solution through an inflow tube ( ). A portable power pack ( ) attached to the pup provides the energization current for actuating the pump. The solution is introduced into the surgical site from the inflow tube through a first cannula ( ) across which there is a relatively small pressure drop. Fluid discharged from the surgical site is drained from the site through a second cannula ( ) across which there is a low pressure drop. A hand controller ( ) is attached to the inflow and outflow tubes. The hand controller contains a valve ( ) for regulating fluid flow through the outflow tube. A pump control circuit ( ) is also disposed in the hand controller. Based on the actuation of buttons ( ) mounted to the hand controller, the pump control circuit regulates the energization signal applied to the pump so as to regulate the rate at which solution is discharged from the pump.

International Classification:

A61M 100

US Classification:

604 35, 604 33, 604249

Abstract:

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.

International Classification:

A61B 17/58

US Classification:

606 62, 606 63

Abstract:

Apparatus for bone reinforcement, fixation and treatment of diseased or fractured bones including a supporting structure optionally coated with therapeutic agent is provided. The supporting structure or device may be collapsible upon deployment at the surgical site, and include fixation features such as anchors to securely position in place once deployed. Bone cement or other material may be provided to alternatively secure the positioned supporting structure for treatment. A lockable bone fixation device is described that comprises: a sleeve adapted to be positioned in a space formed in a bone; a guidewire adapted to guide movement of the sleeve; and an actuable lock adapted to secure the sleeve within the space of the bone from an end of the device.

US Classification:

606 66, 606 63

Abstract:

A bone fixation device is provided with an elongate body having a longitudinal axis and having a flexible state and a rigid state, a plurality of grippers disposed at longitudinally spaced locations of the elongated body, a curved rigid hub connected to the elongated body, and an actuator operably connected to the grippers to deploy the grippers from a first shape to an expanded second shape. Methods of repairing a fracture of a bone are also disclosed. One such method comprising 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 curved rigid hub on another side of the fracture, and operating an actuator to deploy a plurality of grippers of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone.
