    Abstract: A surgical retractor and a method of minimally invasive surgery, wherein the surgical retractor includes ribs and a mechanism for microns-resolution transferring of linear and rotational movements of the ribs and wherein each rib can be easily replaced without use of any additional tools. According to an embodiment of the present invention the transmission is simpler. Likewise, an auxiliary handle is added to facilitate the insertion of the ribs into the body of the operated patient, and the vast majority of components of the surgical retractor are made with biocompatible, and FDA approved material ULTEM HU 1000 RESIN transparent (radiolucent) to X-ray radiation and are designated for single use.

  • Patent number: 8968192
    Abstract: A retractor system for percutaneous surgery in a patient includes first and second retractor portions positionable opposite one another in an incision of the patient. An actuating member is coupled with and extends between ends of the retractor portions which are positionable above the incision. The actuating member is in communication with a controller which includes a user interface for receiving actuation commands from the user. In response to actuation commands, the actuating member is actuated and its length is adjusted to position the first and second retractor portions relative to one another in the incision. In another form, a method is directed to retracting tissue for percutaneous access to a surgical site in a patient. However, other embodiments, forms and applications are also envisioned.

  • Publication number: 20150045627
    Abstract: A surgical retractor that comprises an integrated light source for creating a working space for the access of dissecting instruments employed during an open surgical procedure is described. The retractor is of the type that comprises two elongated arms mechanically connected by a pivot that allows the retractor to move between a closed and an open configuration. The described retractors further comprise adjustable paddle assemblies located at the distal end of the elongated arms and a unique locking mechanism that allows for the relative separation of the paddle assemblies to be set at any position between the closed and open configuration of the retractor. The design of the retractor provides them with increased functionality while allowing them to be cost effectively produced so that they can simply be disposed of after use.

  • Patent number: 8945003
    Abstract: Various embodiments of the present invention provide a surgical retractor having two blade-supporting arms, which are mounted to be laterally slideable towards and apart from each other by a toothed rack. Each arm supports a respective retractor blade. In some embodiments, the retractor blades are curved in the same direction as each other so that the first blade is concave in the first direction, and a second blade is also concave in the same direction. Alternatively or additionally, in some embodiments, a cushioned material or cushioned sleeve is present on the blades where the blades contact the anatomy. The cushioned material or sleeve may be made of a soft silicone. Further, the cushioned material or sleeve may be coated or molded onto the blade structure, or may be a removable sleeve that is manually slid onto or off of the blade structure. Also, alternatively or in addition in some embodiments, blade-mounted lighting may be provided.

  • Publication number: 20150018625
    Abstract: A surgical site retractor is configured to retract tissue, such as in an intercostal procedure. The retractor may be formed from non-radiopaque material for improved monitoring via x-ray imaging. The retractor may have a rigid retractor and a soft tissue retractor, where the rigid retractor has a plurality of legs and the soft tissue retractor extends between the legs to prevent soft tissue from extending between said legs. The retractor may have a bendable arm with an implement holder, such as distal cuff or clip adapted to resiliently hold an implement such as a tube of an elongated port-access device. A method involves partly installing the surgical site retractor, expanding the surgical site retractor, deploying the surgical implement from outside the body through the incision and into the patient, resiliently capturing the implement with the holder of the arm, and bending the arm to hold the implement in a desired position.

  • Patent number: 8911364
    Abstract: A spine retractor and distractor device comprises spinal process clamps and a retractor assembly, which may be rotatably coupled with the spinal process clamps. The retractor assembly may include a retractor ring, or frame, and a plurality of retractor blades adjustably coupled to the frame, e.g., by clamps. The spinal process clamps can maintain a grip on the spinal processes of the patient, and distraction pliers may be used to impart a distraction force on the spinal process clamps to distract the spinal segments. Additionally, other components, features, or tools, e.g., a light source and/or a camera, can be mounted on the instrument.
