    摘要： An endoscopic surgical instrument for passing a suture through tissue includes a first jaw member, a needle, and a capture feature actuable to grip and retain the suture after the suture has been passed through a tissue body. An actuation mechanism can both move the needle between retracted and extended positions, and move the capture feature between open and closed configurations, via a single actuation. The capture feature may be a trap door which is axially translatable relative to the first jaw member to overlap a portion of the first jaw member and trap a portion of the suture between the trap door and the overlapped portion. The first jaw member may be movable relative to a second jaw member to grasp a tissue body. The instrument can grasp a tissue body, pass the suture through the tissue, capture and retain the suture without being repositioned relative to the tissue.

    摘要： A coupled pair of retractors which are coupled at the distal end to allow the handles at the proximal end to be urged apart to increase the distance between handles to allow for direct line of sight to the surgical site while also allowing the use of curved tools and curved access to the surgical site. A cannula with a cross section taken perpendicular to a straight portion of the cannula that increases between the proximal end of the cannula and the distal end of the cannula allows for direct line of sight to the surgical site while also allowing the use of curved tools and curved access to the surgical site. These tools may be used in a postero-lateral approach from an incision in the back to a target position adjacent to the spine.

    摘要： A method and apparatus include determining a value of a parameter associated with operation of an electrosurgical probe having a particular probe design, and determining whether the value of the parameter is within a range of values that has been predetermined for the particular probe design to indicate that the probe is treating tissue in a desired manner. Power is delivered to the probe according to an algorithm based upon a determination that the value of the parameter is outside the range of values The algorithm delivers power in a pulsed profile including portions of low power and portions of high power. In one embodiment, the tissue treatment is ablation, the parameter is impedance, and the method limits tissue necrosis to less than 200 microns. In another embodiment, the tissue treatment is shrinkage, the parameter is temperature, and the method limits power delivery when the probe is not shrinking tissue.

    摘要： An electrosurgical instrument for ablating cartilage while limiting collateral damage includes a non-conducting head with a small electrically conductive surface. The head of the instrument is coupled to a shaft by a flexible portion. The flexible portion biases the electrically conductive surface towards a tissue surface. The head is pivotably coupled to the shaft such that the electrically conductive surface is oriented substantially parallel to the tissue surface as the head slides across the tissue surface. A method of performing electrosurgery includes positioning the electrically conductive surface adjacent to the tissue surface, and sliding the shaft across the tissue surface with the head pivoting such that the electrically conductive surface is oriented substantially parallel to the tissue surface.
