    摘要： A cannula has a flange and a body with slots extending through the entire flange and into the body. The cannula may also have a longitudinal slot extending its entire length. An obturator used with the cannula may also have a longitudinal slot extending along its length. A surgical method using these instruments includes separating lengths of suture and managing the suture by placing lengths of suture in the slots in the cannula. The cannula and obturator may be used after suture is already in place by placing the suture in the longitudinal slots and then introducing the cannula and obturator to the tissue defect site. The cannula may also be used to deliver a therapeutic implant to the tissue defect site. The instruments and method may be used in mensical surgery.

    摘要： Various embodiments are directed to a surgical instrument comprising, a shaft, and an end effector. The shaft may be coupled to the handle and may extend distally along an longitudinal axis. The end effector may be positioned at a distal end of the shaft and may comprise first and second jaw members, a reciprocating member, a shuttle and at least one cam pin. The first and second jaw members may define first and second longitudinal slots and first and second cam slots and may be pivotable towards one another about a pivot point. The reciprocating member may be translatable distally and proximally parallel to the longitudinal axis and through the first and second longitudinal slots. A distal portion of the reciprocating member may define a blade. The shuttle may be translatable distally and proximally parallel to the longitudinal axis. The cam pin may be coupled to the shuttle and positioned within the first cam slot and the second cam slots.

    摘要： A nested trigger assembly for a surgical instrument may generally comprise a first trigger and a second trigger, wherein the first trigger and the second trigger are movable together on a first stroke of the nested trigger assembly, wherein the second trigger is configured to be biased away from the first trigger after the first stroke and before a second stroke, and wherein the second trigger is configured to be moved toward to the first trigger during the second stroke. A surgical instrument may generally comprise a shaft comprising a proximal end and a distal end, a handle extending from the proximal end, wherein the handle comprises a gripping portion, and a nested trigger assembly extending from the handle. The nested trigger assemble may comprise one of a separable trigger assembly and a divisible trigger assembly.

    摘要： A tissue dicing and separation device comprises a housing having an interior that receives tissue for dicing and separation. The device includes a blade assembly connected to a motor and solenoid. The solenoid reciprocates the blade assembly while the motor clocks the blade assembly during each reciprocation cycle. This reciprocating and clocking action of the blade assembly dices and/or minces the tissue. The housing is filled with a fluid and then the blade assembly is continuously rotated to create a vortex within the housing. The vortex causes the diced tissue particles to separate by particle size. Outlets at different positions along the housing permit withdrawal of a slurry of fluid and tissue particles with the tissue particles having a desired size range. The obtained slurry may be used in conjunction with a fistula plug treatment device and method.
