摘要： Methods and devices for tissue fixation. A cortical button with a rib between two slotted openings. The rib increases the cortical button structural rigidity without increasing palpability. An adjustable loop construct with two discrete locking passages that provides manageable loop reduction and improved tissue coupling. The adjustable loop construct may be coupled to tissue via a passing construct. An assembly with a reduction bar, a button and an adjustable loop construct, the assembly provided assembled in a first configuration that disassembles to guide steps of tissue fixation. The reduction bar may be assembled to the reduction bar for reducing the adjustable loop construct.

摘要： A system for harvesting a tendon graft is disclosed, including a retractor, a guide and a harvesting tool. The retractor is collapsible and upon release, becomes self-supporting to hold open an anatomic space developed in a patient above the tendon. A guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. The harvesting tool includes a working end with a blade edge for cutting into the tendon. The harvesting tool defines a contoured surface for engaging and translating along the guide shaft while assembled to the retractor. The guide shaft and contoured surface limit the trajectory and translation extent of the harvesting tool along and into the tendon.

摘要： Methods and devices for tissue graft fixation include fixation devices attached to an adjustable fixation loop of suture without compromising the graft or requiring additional material to complete the repair. Other fixation devices are attachable to an independent adjustable suture system. Adjustable fixation loops minimize slip/creep of the suture within the loop.

摘要： 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.

摘要： 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.

摘要： A system for improving graft harvesting including a blade guide (320) having a handle (370) and a guide portion with an elongate slot (330). The system may also include a first blade assembly (750) that slides along the elongate slot (330), the blade assembly (750) having a cutting blade (765) rotatably coupled to a handle (780). The cutting blade (765) may include a leading cutting edge and a trailing cutting edge. The blade assembly (350, 750) and blade guide (320) may cooperate to control a depth of blade penetration into a tissue, as the blade slides along the elongate slot (330). The blade guide (320) may include means to stabilize the guide with the tissue.

摘要： 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.
