  • Patent number: 9655673
    Abstract: An electrosurgical instrument includes a housing including an elongated shaft. A stationary actuation member is axially disposed within the elongated shaft and includes a cam pin. An actuating mechanism is operably coupled to the elongated shaft and is moveable relative to the housing to selectively cause movement of the elongated shaft. An end effector includes a pair of opposing first and second jaw members operably coupled about a common pivot. One or both of the jaw members includes a camming slot configured to engage the cam pin. Each jaw member includes an electrically conductive tissue sealing surface adapted to connect to a source of electrosurgical energy. A knife blade is supported in the elongated shaft and moveable in a longitudinal direction to cut tissue disposed between the jaw members. A switch is configured to be engaged by the actuating mechanism to initiate delivery of electrosurgical energy to tissue.

  • Patent number: 9636169
    Abstract: An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly includes a pair of first and second jaw members pivotably coupled to one another via a pivot pin. One or both of the first and second jaw members may be movable from an open position for positioning tissue therebetween to a clamping position for grasping tissue. A detent is operably disposed proximal the pivot pin and extends radially outward from a proximal flange of one of the jaw members. The detent is configured to releasably engage a corresponding slot disposed on a proximal flange of the other jaw member. The detent and slot are configured to control a gap distance between the first and second jaw members when the first and second jaw members are in the clamping position.

  • Patent number: 9456840
    Abstract: A surgical tool including an elongated housing having an outer diameter at a location adjacent the front end which can pass through a targeting tunnel of a targeting guide. The surgical tool also includes a first blade with a first cutting edge, a second blade with a second cutting edge, each blade being movably connected adjacent to a first end of an actuation mechanism in the elongated housing. The blades include an at-rest scissors position and a scalpel position. When in the at-rest position the width of the blades does not extend beyond an outer diameter of the elongated housing and when the blades are in a scalpel position, the blades extend beyond the outer diameter of the elongated housing.

  • Patent number: 9393066
    Abstract: Surgical tools and methods are disclosed. The surgical tool has a first configuration wherein the first tip and the second tip operate as forceps. The surgical tool has a second configuration wherein the first tip and the second tip operate as scissors, wherein rotating the first tip and the second tip about a longitudinal axis of the surgical tool transitions the surgical tool between the first configuration and second configuration. A method of using a surgical tool is disclosed that includes providing a surgical tool having a first tip and a second tip, wherein the first and second tips are configured for use as forceps. The method includes rotating the first tip relative to a longitudinal axis of the surgical tool and the second tip relative to the longitudinal axis of the surgical tool, wherein the rotation reconfigures the first and second tips for use as scissors.
