    摘要: A bending tool for use with a human hand for bending the distal extremity of a guide tube of a medical device having a needle assembly slidably mounted in the guide tube. The distal extremity of the guide tube has a tip. The bending tool is comprised of a shaft sized so that it is adapted to be grasped by the human hand to serve as a handle. The shaft has proximal and distal extremities and a longitudinal axis. A bending construction is mounted on the distal extremity of the shaft and provides a curved bending surface having width and a length and having a proximal and a distal extremity and extending at an angle with respect to the longitudinal axis. The bending construction also has an abutment surface at the distal extremity of the curved surface and extending generally perpendicular to the curved surface. The abutment surface has a hole therein extending in a direction generally perpendicular to the abutment surface and is sized so that it is adapted to receive the tip of the guide tube with the guide tube engaging the curved surface to permit bending of the guide tube by a swinging movement of the shaft in a direction at right angles to the abutment surface.

    摘要: A method and apparatus for delivery of energy by an electro-surgical instrument to a surgical site is disclosed. The apparatus delivers power to electrodes of an electro-surgical instrument during an operation performed at a surgical site. The apparatus includes a processor and a plurality of power delivery channels. The processor signals the onset of an impedance interval and a heating interval. The processor determines a target value of a control parameter to be delivered to a corresponding one of the electrodes. The plurality of power delivery channels are each coupled to the processor and to a corresponding electrode. Each of the power delivery channels responsive to signaling from the processor transitions between the impedance interval and the heating interval. Each of the power delivery channels measures, during the impedance interval, an impedance associated with a delivery of energy to the surgical site by a corresponding electrode. Each of the power delivery channels, during the heating interval, minimizes a difference between a measured value of a control parameter and the target value of the control parameter determined by the processor, to deliver the energy to the surgical site. In an alternate embodiment of the invention a method for controlling power delivery in an electro-surgical instrument is disclosed.

    摘要: Systems and methods are described for a wire based temperature sensing electrode for surgical procedures. A temperature sensing energy delivery device includes an elongated member having a groove formed in at least portion of the elongated member; and a first temperature sensor mechanically connected to the elongated member, the first temperature sensor including a first temperature sensor lead that is routed along the groove. The systems and methods provide advantages in that the wire based temperature sensing electrode for surgical procedures can simultaneously accommodate a temperature sensor and associated leads, exhibit sufficient strength without bulk, and be provided at lower cost.
