Abstract

Arthroscopic instrumentation for use in arthroscopic surgery and similar procedures. The instrumentation includes a cannula having a curved lumen and an elongated, flexible normally straight shape memory alloy probe. The probe is insertable into the lumen of the cannula, which in turn can be directed to a hard to reach operative site. The cannula causes the probe to bend as it passes the curves of the cannula, but the shape memory character of the probe causes the probe to exit the distal end of the cannula in a substantially straight orientation.

Independent Claims | See all claims (19)

  1. 1. Arthroscopic instrumentation comprising a cannula having a curved lumen, an end thereof being directable to an operative location; and an elongated, flexible, normally straight shape memory alloy probe receivable in the cannula for introduction to the operative location, the cannula being configured to cause the probe to bend during its passage through the curved lumen, the shape memory character of the probe causing the probe to exit from the end of the cannula in a substantially straight orientation.
  2. 13. Arthroscopic instrumentation comprising:a cannula having a curved lumen, an end thereof being directable to an operative location; anda pair of elongated, flexible, normally straight nitinol needles receivable in the cannula for introduction to the operative location, the needles being longer than the cannula thereby permitting them to be manually inserted in one end of the cannula and manually withdrawn from the other end;a suture, and connector means associated with each needle for connecting the suture to a proximal end of that needle, the connector means comprising a sheath having complimentary interlockable portions respectively attached to the proximal end of the needle and the suture, the portions being disconnectable to permit the needles to be reconnected to another suture for re-use;the proximal end portion of each needle being of a smaller diameter than the adjacent portion of the needle, and the sheath having an outer diameter approximately the same as said adjacent portion of the needle;the needles and cannula being configured and arranged to permit the needles to be bent as they pass through the curved lumen of the cannula but to exit in a substantially straight configuration without taking a substantial set from the bending thereof.
  3. 16. A method of inserting a probe into an operative location comprising the steps of:placing the distal end of a curved cannula adjacent the operative location;inserting a shape memory alloy probe into the lumen of the cannula from the proximal end of the cannula and advancing the probe through the lumen so that the probe undergoes a bend as it passes through the curved lumen of the cannula but without taking on a substantial set, and forcing the distal end of the probe through the distal end of the cannula from which the distal end of the probe emerges in a substantially straight orientation as it advances toward the operative location.
  4. 17. A method of arthroscopically suturing tissue comprising the steps of:placing the distal end of a curved cannula in alignment with the tissue to be sutured;inserting a shape memory alloy needle through the curved cannula, the needle exiting the cannula in a substantially straight orientation toward the tissue and pulling a suture behind it;advancing the needle until it exits the tissue;inserting a second needle through the curved cannula, the needle exiting the cannula in a substantially straight orientation toward the tissue and pulling the other end of the suture behind it;advancing the second needle until it exits the tissue, and then separating the needles from the suture and tying off the suture.
  5. 18. A method of arthroscopically suturing tissue comprising the steps of:placing the distal end of a curved cannula in alignment with the tissue to be sutured;inserting a shape memory alloy needle through the curved cannula, the needle exiting the cannula in a substantially straight orientation toward the tissue and pulling a suture behind it;advancing the needle until it exits the tissue;inserting a second needle through the curved cannula, the needle exiting the cannula in a substantially straight orientation toward the tissue and pulling the other end of the suture behind it;advancing the second needle until it exits the tissue, and then separating the needles from the suture and typing off the suture; and re-attaching the needles to another suture.
