摘要:
An anchor is provided for placement in or against tissue. The anchor includes a flat fibrous construct having a first end and a second end; and a filament having a first end and a second end passing through the fibrous construct in two locations including a first passing location nearest a first end of the fibrous construct, a second passing location nearest a second end of the fibrous construct, the filament remaining free to slide through the first passing location and the second passing location such that the filament can be removed from the flat fibrous construct from the first end of the fibrous construct and the second end of the fibrous construct. The anchor can be inserted into a bone hole and deployed.

A suspensory fixation device has an elongated anchor member adapted to be transversely situated at the exit of a bone tunnel. A graft supporting loop member formed of a pair of parallel suture limbs extending from a bight portion is suspended transversely from the anchor member and has a loop length which is adjustable so the graft ligament can be supported in the bone tunnel at varying distances from the anchor member. When a graft ligament is attached to the saddle end of the loop member, the length may be shortened by pulling distally on the pair of limbs to pull the graft ligament into the bone tunnel. When tension is applied to the loop member by the graft pulling the loop proximally, the bight portion of the suture automatically locks the graft supporting loop member in place.

The invention includes systems and methods for controlling devices including surgical instruments using a wireless footswitch. The systems of the invention include a wireless footswitch, a footswitch adapter, and an electric console for powering and controlling surgical instruments. The systems of the invention further include a wireless footswitch for controlling battery powered surgical instruments. The methods of the invention include syncing a wireless footswitch with a controlled device or a wireless footswitch adapter using a lower power wireless mode, then signaling the controlled device or wireless footswitch adapter using a higher power wireless mode. The systems and methods of the invention include using a wireless device or wireless footswitch adapter to monitor transmissions from other wireless devices to prevent syncing with the wireless footswitch adapter using the same channel or network identification as other wireless devices or wireless footswitch adapters.

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.
摘要:
A dual pump irrigation/aspiration pump system capable of operating in a plurality of different modes suitable for a variety of different endoscopic surgical procedures. The system monitors actual or calculated intra-articular pressure and adjusts flow to maintain surgeon requested pressure at the surgical site while controlling outflow. The irrigation/aspiration pump system has an inflow pump and tubing dedicated to communicating fluid to the surgical work site and an outflow pump and tubing dedicated to removing fluid from the work site at a controlled rate. The system further has different size inflow and outflow pumps and tubing cassettes, means for altering the outflow fluid flow rate to accommodate a surgical tool and a means for declogging the surgical tool in the event of blockage. In a preferred embodiment a pressure control system provides inferred pressure information representative of the pressure at the work site.

摘要:
A method for securing first and second tissues with a suture anchor. The method includes forming a borehole in the first tissue; threading a suture through the second tissue forming a loop in the suture with the tissue thereby secured in the loop, the loop defining two suture portions; attaching the two suture portions to the anchor whereby the two suture portions are threaded through the anchor and initially movable with respect to the anchor; and providing a force to a shaft of the anchor, the force causing clamping of the two suture portions in the anchor and deformation of a deformable portion of the anchor to cause the deformable portion to engage a wall of the borehole thereby to secure the suture anchor in the first tissue and the loop holding the second tissue to the suture anchor.
