International Classification:

A61B 17/00

Abstract:

A harvesting assembly for harvesting a tissue graft from surrounding tissue is disclosed including a guide. The guide includes a means for fixedly engaging with an anterior surface of the tendon. The guide also includes a means of guiding a cutting blade along a preferred trajectory into and along a length of the tendon. The guide also includes a means of guiding a truncating blade along a preferred trajectory across a width of tendon. The cutting blade may include two parallel blades for forming lateral sides of the tendon graft simultaneously. Each of the two parallel blades may define a leading edge that extends along at least a 90 degree arc that is equidistant from a stop on the cutting blade. The stop in combination with the guide may limit a cut depth into the tendon for a range of cutting blade handle elevation angles.

International Classification:

A61B 17/17
A61B 50/33

Abstract:

Surgical drill guides have modular configurations and are adapted to accommodate a wide range of anatomy. The surgical drill guides are adapted to be removed while leaving a guide wire in its intended location in human bone. The distal end of the drill guide acts as a safety stop for the guide wire by preventing the guide wire from penetrating too far past the far side of the bone.

International Classification:

A61F 2/08

Abstract:

An adjustable fixation system for coupling a tissue or graft to bone is disclosed including a suture construct including a first limb, a second limb and a body therebetween. The body is continuously braided with the first and second limbs and has a longitudinal passage therethrough. The first and second limbs define a braided portion including a braided core. The suture construct is configured to form at least one adjustable loop formed by passing the first limb between braids of the suture construct, along the longitudinal passage and back out between braids of the adjustable suture construct. Tension on at least one of the first or second limbs reduces a diameter of the longitudinal passage around a length of the first limb and thereby the braided core disposed along the body longitudinal passage and knotlessly locks the adjustable loop.

International Classification:

A61B 17/16

Abstract:

Retro guidewire reamers include a drill having a tubular shaft configured to be disposed over a guidewire and at least one cutting member movably disposed adjacent the distal end of the shaft. A slide actuator is moveably coupled to the shaft and to an actuator wire slidable along the shaft. The actuator wire is operative to move the at least one cutting member between a closed position and a deployed position when the slide actuator is moved along the shaft. The retro guidewire reamers include mechanisms to protect the mechanical joint between the actuator wire and the slide actuator which prevent the actuator wire from disengaging from the slide actuator when the cutting member is obstructed by a guidewire.

International Classification:

B05B 11/00

Abstract:

A fluid supply assembly includes a holding member and a plurality of output heads. The holding member has an assembling surface, an outer surface opposing to the assembling surface and a plurality of through holes. The through holes extend from the assembling surface to the outer surface respectively. The output heads are fixed at the through holes, each protrudes from the assembling surface. Each output head has an output opening The output heads respectively cover the through holes. A fluid flows from one of the output openings after passing through one of the through holes.
