摘要： A suture anchor applier comprises a needle, a flexible shaft, and flexible sleeve. The suture anchor applier is flexible enough to allow passage through and manipulation within a working channel of an articulated endoscope. The suture anchor applier is also stiff enough to resist buckling or bending when extended distally beyond the end of an endoscope and as the needle penetrates into tissue.

摘要： An improved articulation mechanism is described in conjunction with a therapeutic ultrasound instrument. Ultrasonic vibrations, when transmitted to organic tissue at suitable energy levels and using a suitable end-effector, may be used for the safe and effective treatment of many medical conditions. The mechanism includes an actuating arm with a collar operatively connected to the actuating arm. The collar converts rotation of the actuating arm into a plurality of actuations of the surgical instrument. In one embodiment the collar includes two ranges of motion, where the first range is used to articulate the surgical instrument, and the second range is used to actuate the surgical instrument. Such instruments are particularly suited for use in minimally invasive procedures, such as endoscopic or laparoscopic procedures.

摘要： The present invention describes ultrasonic surgical instruments that include a mechanism for clamping tissue against an ultrasonic blade, including an arrangement for detachably mounting a clamp arm to the instrument. The ultrasonic surgical instrument comprises a waveguide adapted to be acoustically coupled to an ultrasonic transducer, and to transmit ultrasonic energy to an end-effector located at the distal end of the waveguide. A support tube extends from a handle assembly and surrounds at least a portion of the waveguide, terminating proximal to the end-effector. A clamp arm is detachably mounted to the distal end of the support tube. An actuation element is operatively coupled to the clamp arm. The ultrasonic surgical instrument may also include a clamp arm release. The actuation element comprises a first range of motion and a second range of motion, whereby moving the clamp arm release from a second position to a first position increases allowable motion of the actuation element from the second range of motion to the first range of motion, thereby facilitating release of the clamp arm from the support tube. The ultrasonic surgical instrument may include the capability for the clamp arm, actuation element, support tube and waveguide to rotate within the handle assembly.

摘要： A method for establishing a surgical port for endoscopic or arthroscopic surgery is disclosed. A trocar is initially provided, and the obturator of the trocar includes a flat cutting blade, a shield that moves proximally and distally from a precock position to an extended position, a precock lever to move the shield proximally to expose the flat cutting blade, and a shield retaining assembly to constrain the shield in the proximal position. "Precocking" the trocar of the present invention moves the shield from the distal position wherein the flat blade is covered, to a proximal position wherein the flat blade is exposed, and the shield is constrained by the shield retaining assembly. Once the flat cutting blade is exposed, the skin of the patient is incised with the flat cutting blade of the obturator. The flat blade of the trocar is inserted into the incision and a penetrating force is applied so that the flat blade penetrates into the internal body cavity of the patient. The obturator assembly is removed from the cannula assembly so that the surgical access port is provided into the internal body cavity of the patient. This method eliminates the need for a separate surgical sharp to initially incise the skin before penetration is effected.

摘要： A surgical trocar has a cannula assembly including a sleeve having a proximal end, a distal end and a passageway therethrough. A housing having an opening is located at the proximal end of the sleeve and is aligned with the passageway of the sleeve. The trocar also includes an obturator assembly which is insertable in the cannula assembly. The obturator assembly includes a handle and an obturator shaft. The obturator shaft has a proximal end connected to the handle and a distal end opposite the proximal end. A penetrating tip is located at the shaft distal end for penetrating tissue. A protector having a distal end is slidably disposed around the obturator shaft for covering the penetrating tip. The protector has an aperture at its distal end for permitting the penetrating tip to pass therethrough. The protector also includes a flexible proximal end movable against the obturator handle to expose the penetrating tip when a proximal force is asserted against the protector. A seal assembly is located in the housing for sealing against the obturator assembly or surgical instruments passed through the cannula assembly. The seal assembly includes an upper seal arrangement having an aperture. The seal assembly also includes a pressure seal located beneath the upper seal arrangement. The pressure seal includes a pair of side walls. At least one rib is located on the inner surface of each side wall.

摘要： A safety-shielded trocar having an obturator with a linear cutting edge surface defining a base width substantially less than the diameter of the safety shield is disclosed. When the trocar is inserted through tissue, the tissue dilates from the width of the linear incision to accommodate the size of the safety shield of the trocar, thus making it possible to provide an access opening greater than the incisional width made by the linear cutting edge surface of the obturator. In a preferred embodiment, the safety shield has a shield tip region which is asymmetric to facilitate the dilation of the tissue as the trocar is inserted.

摘要： A trocar having an obturator with an obturator housing, a piercing tip and a rigid stem is disclosed. The piercing tip has a cutting edge surface and first and second spaced-apart legs generally parallel to each other extending away from the cutting edge surface. The stem is attached to the obturator housing at a first end of the obturator, and the legs of the piercing tip straddle the stem at an opposite end of the obturator. The straddling of the legs about the stem of the obturator fixes the piercing tip to the stem. The attachment of the piercing tip to the stem provides a secure attachment. The trocar is easy to manufacture and assemble, and the component parts can be readily disassembled. The piercing tip attachment is especially advantageous when the piercing tip is configured generally as a razor blade.

摘要： A trocar and trocar obturator assembly having an obturator and a locking mechanism responsive to proximal, axial movement of the trocar obturator is disclosed. The trocar obturator has an elongated obturator shaft having a proximal end and a distal end with a piercing tip mounted thereto. The proximal end of the trocar obturator shaft is slidably mounted in a handle such that the obturator shaft is moveable axially. A protective safety shield having a distal end and a proximal end with a flange member mounted to the proximal end is slidably mounted on the trocar obturator. The safety shield is moveable, axially, between an extended distal position and a retracted proximal position. The protective safety shield is disposed concentrically about the obturator. A lockout arm for locking the safety shield in a locked extended position is mounted in the trocar obturator handle. An actuating collar member is mounted to the proximal end of the obturator shaft in the obturator handle and is moveable with the obturator shaft. The obturator collar disengages the locking arm when moved proximally and engages the locking arm when trocar is armed. The trocar obturator assembly may be concentrically mounted in a trocar cannula having a passageway for receiving the trocar obturator and safety shield. The locking mechanism is actuated by proximal, axial motion of the obturator.
