  • Patent number: 6719764
    Abstract: The present invention allows for the performance of surgical procedures that involve the passing of sutures through tissue in a location that is facilitated by the suturing instrument deploying the suture in a forward-facing direction in relation to the suturing instrument. In addition, this invention provides for the catching and retrieval of the suture after it is passed through the tissue. In particular, this suturing instrument may be placed or positioned in the body such that a suture may be passed into a tissue of the body while the face of the distal end of the instrument abuts the tissue.

  • Patent number: 6716224
    Abstract: An instrument and method for tying two suture ends into a knot. A tubular outer member is provided with a transverse slot for capturing a length of one of the suture ends therein. A slidable inner member has a pair of diametrically opposed, suture engaging fingers for pushing the captured suture from the tubular member and for rotating it to form a loop between the fingers. The other suture end is passed through the loop to create a knot. The instrument is then repositioned and used as a knot pusher so the knot may be tightened and properly positioned. Successive use of the instrument to create successive loops and knots ultimately results in a final knot securing the suture ends.

  • Patent number: 6712829
    Abstract: An instrument for exerting an end of a vessel over an end of a tubular workpiece. The instrument has a body having an axial bore, and a mandrel mounted within the axial bore and partially extending from the distal end of the axial bore. The mandrel is made from a sheet of spring-like material rolled into a conical shape. The distal end of the mandrel is insertable into the lumen of the vessel. A plunger substantially contained within the axial bore and axially moveable, extends into the proximal end of the mandrel and presses against an inner surface of the mandrel when the plunger is moved from a retracted position to an extended position, thereby causing the distal end of the mandrel to expand radially and the proximal end of the mandrel to contract radially. An optional spring mounted to the body provides a biasing force to move the plunger to the retracted position and to allow the mandrel to return to the conical shape.

  • Patent number: 6685717
    Abstract: A surgical instrument for relieving carpal tunnel syndrome has an elongated member including a first portion for handling and a second portion. The second portion has a first surface, a second surface, and a blade on the first surface. The blade has a trailing edge and a sharp, convex leading edge. The leading edge rises gradually at a first angle with respect to the first surface so that when the leading edge is pushed against tissue to make an incision, damage to the surrounding tissue is reduced. The first angle is less than 90 degrees. In carpal tunnel release surgery, a transverse incision is made in the patient's distal wrist crease with a surgical instrument. The surgical instrument is positioned below the, transverse carpal ligament and advanced in a closed procedure towards the patent's fingertips until the transverse carpal ligament is completely transected.

  • Patent number: 6666875
    Abstract: A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated or otherwise activated using the secondary battery as a driving power source to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument by induction from the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged without compromising sterility.
