  • Methods and devices for tissue retraction
    Patent number: 8821394
    Abstract: Methods and devices are provided for retracting tissue. In one exemplary embodiment, a retractor is provided that includes a base, a plurality of blades extending from the base, and an actuator coupled to the base and operatively connected to the blades. The actuator can be configured to be actuated to move the blades relative to the base, thereby allowing the blades to retract tissue. The actuator can be self-locking so as to allow the blades to be freely movable within their entire range of motion relative to the base through actuation of the actuator without using another mechanism to lock the blades in a fixed position and to unlock the blades from the fixed position. The retractor can be formed from one or more radiolucent materials.

  • Surgical Access Tube
    Publication number: 20140243604
    Abstract: Implementations of the present disclosure provide an access tube including a wall structure and an optional handle extending from the wall structure. Selectively weakened areas facilitate selective resection of the wall structure to reveal windows that accommodate lateral intrusions by surrounding anatomical structures and/or provide increased access to an intervertebral disc. For example, a first distal weakened portion is configured to form a first window to afford lateral intrusion of a spinous process. A second distal weakened portion is configured to form a second window to afford lateral intrusion of facet. A proximal weakened portion is configured to afford additional angular access on a proximal end of the tube.

  • COMPRESSOR-DISTRACTOR
    Publication number: 20140243903
    Abstract: A tool is disclosed for use in distracting and compressing fractures of any of a variety of bones. In particular, the tool has a pair of engaging arms, one arm having a hook element to engage a bone plate connected to one side of a fracture, and the other arm having at least one recess for engaging a head of a bone screw or guide wire connected to the other side of the fracture. Actuation of the tool causes the opposing bone segments of the fracture to be pushed apart or drawn together, depending on whether the tool handles are squeezed together or pulled apart. The tool may have a scissors joint that allows the ends of the tool to maintain a parallel alignment during operation, thus reducing the chances for misalignment of the bone segments during operation.
