Abstract: A flexible screw and method for non-rigid fixation between two bones. The flexible screw includes a head, and a body including a thread portion with a flexible shaft portion extending therebetween. The head has a diameter greater than that of the flexible shaft portion. The thread portion has a plurality of rigid threads while the flexible shaft portion has plurality of openings arranged in a pattern configuration. The openings extend at least partially through the flexible shaft portion. The flexible screw can be used for non-rigid fixation by inserting the thread portion in a first bone while the head is positioned on a distal side of an adjacent second bone. The flexible screw is tightened such that the flexible shaft portion extends in the joint between the first bone and the second bone. The flexible shaft portion provides stability while also adding back motility lost by the reduction in the size of the joint.

Abstract: An electrosurgical instrument having a knob with an internal gear, a shaft extending from the body with an external gear that is coupled to the internal gear, and a pair of jaws mounted to the shaft. The internal gear and the external gear have a gear ratio greater than 1:1 so that the shaft and jaws rotate at a faster than the knob when it is turned by a user. The axis of rotation of the knob is offset from the axis of rotation of the shaft so that the knob can project asymmetrically from the body for easier rotation by a user.

Abstract: Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. An anchoring device is described that comprises an anchor body having compressible tabs with teeth, and a spreader that forces the compressible tabs into an expanded state when inserted into anchor body, facilitating engagement between bone and the teeth of the compressible tabs. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (“ACL”) reconstruction.

Abstract: A suture passer for use in arthroscopic soft tissue repair procedures. The suture passer includes a cannulated needle having a distal tip. A post is slidable within the cannulated needle. A snare is slidable within the cannulated needle between an extended position and a retracted position. In the extended position, the snare extends from the distal tip of the cannulated needle and in the retracted position, the snare extends around the post. The suture passer may have a handle extending proximally from the cannulated needle. In use, suture is passed through an open region between the snare and the post in the extended position. As the snare and, in some cases, the post, are retracted, the snare extends around the post and closes the open region, trapping the suture between the snare and the post in a closed region.

Abstract: A force limiting assembly for a surgical instrument that has a handle and a lever pivotally mounted to the handle at a pivot point for movement of an internal drive shaft. The lever is coupled to the drive shaft by a cantilever spring that is positioned within the lever. The free end of the cantilever is spaced apart from the pivot point of the lever and coupled to the drive shaft via stops positioned on the drive shaft on either side of the free end of the cantilever spring. As the lever is pivoting by a user, the forces move the drive shaft and bias the cantilever spring, thereby reducing and ultimately limiting the amount of force that a user may apply to the drive shaft via operation of the lever.

Abstract: An all-suture anchor for generating bone compression and increasing interference fixation. The all-suture anchor includes a fibrous construct which is movable between a pre-deployment configuration and a deployed configuration. The fibrous construct has a first density. The all-suture anchor also includes a monofilament woven through the fibrous construct. The monofilament has a second density, which is different than the first density. The contrasting densities (i.e., irregularities) aids in the “locking” ability of the all-suture anchor by greater purchase in hard and soft bone. The all-suture anchor can have a variety of textures, barbs, and rigidities that aid in creating irregularities within the bone surface for more secure fixation.
