Abstract
An elongated suture anchor driver having a suture retaining means at its proximal end. The driver receives a suture anchor at its distal tip and has a throughbore for enabling suture attached to the suture anchor to pass through the driver from its distal end to its proximal end. The proximal end of the driver is provided with a channel and a fixed post for guiding the suture exiting from the throughbore into an annular recess. A spring loaded slidable cylindrical sleeve acts against the suture in the recess to frictionally retain the suture, thereby securing the suture anchor and suture within the driver.
Claims13
A driver for driving a suture anchor having suture attached thereto, the driver comprising:
- an elongated shaft having an axis, a proximal end and a distal end;
- an anchor receiving means at the distal end of said shaft for receiving a suture anchor to be driven;
- means for enabling suture to pass from said distal end to said proximal end of said shaft;
- and
- suture retaining means at the proximal end of said shaft for retaining said suture, said retaining means comprising:
- a fixed retention means immovably secured to said shaft for guiding said suture in a predetermined direction, said fixed retention means comprising a radially outwardly extending projection;
- a movable compression means for frictionally engaging said suture, said compression means longitudinally movably attached to said shaft;
- spring means for urging said compression means toward said fixed retention means to retain suture therebetween.
A driver for driving a suture anchor having suture attached thereto, the driver comprising:
- an elongated shaft having an axis, a proximal end and a distal end;
- an anchor receiving means at the distal end of said shaft for receiving a suture anchor to be driven;
- means for enabling suture to pass from said distal end to said proximal end of said shaft;
- suture retaining means at the proximal end of said shaft for retaining said suture, said retaining means comprising:
- a fixed post means immovably secured to said shaft for guiding said suture in a predetermined direction;
- a movable compression means for frictionally engaging said suture, said compression means movably attached to said shaft;
- spring means for urging said compression means against said fixed post means to retain suture therebetween.
A method for securing a suture anchor, with suture attached thereto, to a driver having an external surface, a proximal end, a distal end and an anchor engaging means at said distal end for engaging said anchor, said method comprising the steps of:
- passing said suture from said distal end to said proximal end;
- seating said anchor in said anchor engaging means;
- providing at said proximal end a spring actuated suture retaining means for retaining suture, said retaining means comprising a fixed radially extending retention means immovably secured to said driver for guiding said suture in a predetermined direction, a longitudinally movable compression means movably attached to said driver and spring means for urging said compression means toward said fixed radially extending retention means to retain suture therebetween;
- retracting and holding said movable compression means to form a predetermined space between it and said fixed radially extending retention means;
- passing said suture from said proximal end into said predetermined space;
- and
- releasing said movable compression means to enable it to move longitudinally to thereby secure said suture between said movable compression means and said fixed retention means.
A method for securing a suture anchor, with suture attached thereto, to a driver having a proximal end, a distal end and an anchor engaging means at said distal end for engaging said anchor, said method comprising the steps of:
- passing said suture from said distal end to said proximal end;
- seating said anchor in said anchor engaging means;
- providing at said proximal end a spring actuated suture retaining means for retaining suture, said retaining means comprising a fixed retention means immovably secured to said driver for guiding said suture in a predetermined direction, said fixed retention means comprising a radially outwardly extending projection, a movable compression means movably attached to said driver and spring means for urging said compression means toward said fixed retention means to retain suture therebetween;
- retracting and holding said movable compression means to form a predetermined space between it and said fixed retention means;
- guiding said suture from said proximal end contiguously past said projection and into said predetermined space;
- and
- releasing said movable compression means to enable it to move longitudinally to thereby secure said suture between said movable compression means and said fixed retention means.
