摘要： An electrosurgical generator which provides a constant power output particularly suited for cutting arc formation at an active electrode which exhibits a dynamic active surface area of varying geometry. Essentially constant power-based control is achieved through the utilization of a d.c. link voltage the level of which functions to establish the amplitude of the output of an RF resonant inverter. A dual loop feedback control is described wherein output power based control signals are slowly introduced at low gain, while link voltage based controls are comparatively rapidly applied. Enhanced development of a controlling d.c. link voltage is achieved through the utilization of an input network incorporating a power factor correction stage.

摘要： A target tissue volume is accessed with a cannular instrument (222), the tip surface of which supports a precursor electrode assemblage (138) which is electrosurgically excitable. The instrument tip initially is inserted through an incision made in the skin of a patient utilizing a retractor instrument (20), the tips of which are located at a proper depth for positioning the precursor electrodes of the recovery instrument. The retractor components (22,24) also are configured to define a guidance channel (220) for receiving the tip of the recovery instrument. By stabilizing the instrument when the precursor electrodes are adjacent the tips of the retractor components and then slidably removing the retractor apparatus along the surface of the instrument, the tissue is "set" to assure proper precursor electrode positioning.

摘要： Samples are recoverable from very dense tissue utilizing an instrument (10) incorporating a capture component (220) formed with leafs (228-232) extending to leaf tip regions supporting a stainless steel pursing cable assembly (278-282). The cables of this assembly are electrosurgically excited to define a confronting leading edge and extend rearwardly to a terminator component (348). Motor drive is imparted to the capture component to deploy the leafs at a substantially constant initial angle of attack. During this procedure the terminator component is drawn forwardly by the cable until encountering a cable stop (360) whereupon continued motor operation loads the cables in tension. By applying a preliminary loading tension to the cables before encountering the pursing cable stop, the angle of attack of the leaf tip region is gradually altered to lessen the development of lateral tissue induced forces against the leaf structures.

摘要： The capture component of tissue retrieval apparatus is strengthened to improve its structural integrity when utilized within very dense tissue. Eyelet structures carrying pursing cable are improved through the utilization of slightly expanded constant widths with diminished lengths to avoid fold back phenomena. The pursing cables employed with the capture component exhibit more than a 100 % improvement in tensile strength at high electrosurgical cutting temperatures through the utilization of strands having about a 1.4 mil diameter formed with a type 316 stainless steel.

摘要： Method for carrying out the recovery of an intact volume of tissue wherein a delivery cannula tip (22) is positioned in confronting adjacency with the volume of tissue to be recovered. The electrosurgical generator employed to form an arc at a capture component extending from the tip is configured having resistance-power profile which permits recovery of the specimen without excessive thermal artifact while providing sufficient power to sustain a cutting arc. For the recovery procedure, a local anesthetic employing a diluent which exhibits a higher resistivity is utilized and the method for deploying the capture component (200) actuation interspersed with pauses of duration effective to evacuate any accumulation or pockets of local anesthetic solution encountered by the cutting electrodes.
