Embodiments of devices for converting continuous rotational motion into oscillating motion are disclosed herein. In one embodiment, an oscillation device can include an input shaft that rotates about a first axis, a portion of the input shaft defining an eccentric section that defines a second central axis offset from the first axis, a connector rotatably coupled around the eccentric section, an oscillating shaft offset from the input shaft that rotates about a third axis, and a pin coupled to the oscillating shaft and extending towards the connector. The connector includes a sleeve slidably receiving an end of the pin, and continuous rotation of the input shaft about the first axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third axis.

The disclosure provides apparatus and methods of use pertaining to syndesmosis reinforcement. Embodiments include a clamp having two jaws that extend toward each other to clamp two bone portions therebetween. The clamp may include an angle gauge and an adjustment mechanism having a force gauge that combine to enable the compression of the two bone portions in an optimal direction or angle and at an optimal, measurable compression force. Embodiments also include a tension instrument configured to knotlessly lock a flexible strand construct between two anchors at the same optimal direction and tension applied by the clamp. Further embodiments include an exemplary syndesmosis reinforcement procedure that employs the clamp and the tension instrument to construct a ligament reinforcement construct that achieves optimal anatomic positioning in both directional alignment and the reduction force applied by the construct. Other embodiments are disclosed.

Surgical instruments, systems and methods are described for selecting a size and cutting bone for inserting of an intervertebral disc prosthesis. The surgical instrument includes a combined intervertebral disc prosthesis sizing trial and a slot or channel cutter which is movable with respect to the sizing trial.

This surgical instrumentation assembly is for positioning a shoulder prosthesis, the shoulder prosthesis comprising a patient-specific shoulder implant adapted to fit onto a glenoid cavity of the scapula of a patient. The assembly comprises a patient-specific impacting device having an underside surface congruent with the glenoid cavity of the scapula of the patient, said underside surface being provided with protrusions adapted to perforate the cortical bone of the scapula upon impact of the impacting device against the scapula by a one-sided translation movement.

Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture, and can be useful in many different tissue repair procedures that are disclosed in the application. In one exemplary embodiment, one or more constructs are disposed on a suture threader, which can be used to associate the construct(s) with a repair suture(s) being used to repair the soft tissue. Tissue augmentation constructs can include various blocks and patches, among other formations. Exemplary methods for manufacturing the tissue augmentation constructs are also provided.

A tool for scrubbing, removing tissue from the medullary cavity or joint cavity of a bone or removing cartilage and/or cortical bone from a joint cavity has a proximal end, a distal end, and a cannula extending therethrough. The distal end includes at least one scraping surface and/or cutting surface to soften marrow in the medullary cavity or joint cavity as the scraping and/or cutting surface(s) are rotated or otherwise moved relative to the medullary cavity or joint cavity. When used, the tool may be attached to a drill and the cannula receives a K-wire previously inserted into the medullary or joint cavity. The drill rotates the tool around the K-wire and pushes the tool over the K-wire into the medullary cavity or joint cavity.

Methods, systems and apparatuses are provided for torsionally stabilizing a spinal motion segment. One or more implants are placed between two vertebrae to provide torsional stabilization. In particular, one or more implants may be fixed between a superior vertebral body, such as at the spinous process, and an inferior vertebral body. The implants may be connected to the superior vertebral body using a fixation device such as a turnbuckle, an outrigger, a thimble, an endobutton, a suture plug or combinations thereof. The implant may also be connected to the inferior vertebral body using various types of hardware, including staples, screws and anchors. The implant may be kept in tension to provide torsional stabilization and may be comprised of one or more sutures. A multi-functional instrument having one or more arms having holes can be used to clamp onto the superior vertebral body and guide one or more implants to various locations for fixation in accordance with the methods described herein.

A probe insertion device for implanting a probe into tissue includes a rigid base that selectively attaches to the probe due to a bond between the base and the probe, that provides a structural backbone to the probe, is longitudinally aligned with the probe, and can be adapted to receive a fluid between the base and the probe. The probe insertion device can include a surface covering at least a portion of the base that reduces the bond between the base and the probe in the presence of the fluid.

Embodiments of the invention provide a surgical instrument for removing a hook nasal hump. The surgical instrument includes a handle including a blade having a prominent edge at a front end thereof, and guide members coupled to both sides of the handle and configured to slide the handle; forward and backward. The surgical instrument further includes a mounting concave portion configured to mount the nasal hump, which is a surgical subject, formed at a front portion of the guide members, and an upper and a lower plate, each having a shape of a flat sheet and a predetermined length. The blade of the handle is integrated between the upper plate and the lower plate, a width of the blade is smaller than a width of the upper and lower plates, sliding grooves are formed between both sides of the blade and the upper and lower plates, and the guide members comprise rod-shaped rails inserted into the sliding grooves, so as to slide the handle. The surgical instrument further includes mounting rods of which one side of each mounting rod is coupled to a front portion of each rail and of which the other side is coupled to the mounting concave portion for hooking onto the nasal hump.

A resecting probe includes a shaft assembly having an outer sleeve and an inner sleeve. The outer sleeve has an axial bore and an outer window in a distal side thereof, and the inner sleeve has an axial extraction channel and inner window in a distal side thereof. The inner sleeve is rotationally disposed in the axial bore of the outer sleeve to allow the inner sleeve window to be rotated in and out of alignment with the outer sleeve window, and the shaft assembly forms a flow aperture in a distal portion when the inner cutting window and the outer cutting window are out of alignment. An electrode is carried on the inner sleeve, and a motor drive is coupled to rotate the inner sleeve relative to the outer sleeve. A controller is coupled to the motor drive and controls rotation of the inner sleeve.
