The present invention provides an apparatus and method for securing a light guide to a light source. The light guide has an end termination having a predetermined size and the light source has an opening with an axis for receiving the end termination. The opening is adaptable to receive and grip light guides of different sizes. In one aspect of the invention, an actuator is operable to expand and shrink the opening. In another aspect of the invention, one or more shields are provided to block light from exiting the light source except when a light guide is connected to the light source.

A drill bit has a cylindrical proximal end coupled to a driving device with a central axis of rotation about which the proximal end rotates. A distal portion of the drill bit is a cutting device attached to the proximal end in such a way that it extends outside the periphery of the proximal end for a distance less than the entirety of the circumference of the proximal end. A guide wire extends through a passageway in the bit and is provided to create a pilot hole before the distal portion enlarges that hole. With this configuration of the cutting device, it is possible to position the cutting device in the distal portion in a direction facing away from the medial femoral condyle so that the proximal end of the drill bit can slide past the medial femoral condyle, with its axis of rotation much closer to that condyle than would be the case in prior art drill bits.

A two piece graft fixation arrangement includes a graft block engageable with a graft and a transverse member engageable with the graft block to fix the graft block in a bone tunnel. Instruments and methods are presented for installing a graft in a bone tunnel and anchoring the graft with a transverse member placed through a transverse bore intersecting the bone tunnel.

An apparatus, system and method are presented by which certain surgical procedures normally done by powered surgical handpieces may be accomplished by powered arthroscopic handpieces, thus obviating the need to use powered surgical handpieces.

A suture management system useful in endoscopic surgery, particularly in arthroscopic instability and rotator cuff procedures comprises a plurality of elongated tubes, sometimes referred to herein as suture organizers. The tubes can have a suture loop through them to ensnare matching suture ends of a given suture so that the tube can be slid down over the matching suture ends and into a cannula. The tube with the matched suture ends can be clamped over the suture strands to fixate the tube as another suture is manipulated through the tissue and then in turn has its matching suture ends pulled through another tube for subsequent tie-off. A rack is provided to hold the tubes with loops therein before use.

A shock mounting system for a 3-chip video camera. The system comprises a pair of support plates for spanning the junctions between the various components (prisms, etc.) of a standard charge coupled device (CCD) color camera having 3 CCD's, and an elastomeric boot molded to fit between the CCD camera assembly and the housing within which it is situated. The support plates are made of a material having similar thermal characteristics to the CCD assembly and are suspended within the elastomeric boot.

A cycle counter for sterilization cycles for a disposable instrument features a plurality of tabs. With each sterilization after the initial use, a tab is removed by medical personnel. The instrument is disposed of after the final use with no tabs left.

A guide bushing for a coring reamer having a tapered member with its largest diameter at its first end so that the guide bushing frictionally engages an internal surface of the reamer with a line contact. The guide bushing has a passage sized to slidably receive a guide pin. In use, the bushing advances in the proximal direction within the coring reamer along a guide pin while the excavated bone enters the passageway through the reamer. A storage package specifically designed for the reamer assembly is employed to remove the excavated bone from within the reamer. The package has a closed distal end and an open proximal end closeable with a cap. With the coring reamer received in cantilevered fashion through a central opening of the cap of the tube, and with an adapter that couples the coring reamer to a handpiece installed, a wrench is placed over the adapter and turned while the user grips peripheral surfaces of the cap to prevent rotation of the coring reamer. A plunger is inserted through the opening through the coring reamer from the proximal end and is pushed through the reamer until the bone core and bushing fall out of the distal end of the coring reamer.
摘要:
A toggling suture anchor, insertion tool, and method for anchoring at least one suture thread to a bone are provided. The toggling suture anchor is anchored by operation of the insertion tool, the suture anchor including a shaft having a longitudinal axis, a distal end, a proximal end, at least one eyelet hole to receive the suture thread, and at least one suture groove to provide a location to guide the suture thread while inserting the suture anchor into the bone; and at least one locking wing extending radially from the shaft, the locking wing being provided on one side of a first plane, the first plane including the longitudinal axis of the suture anchor.
