  • Patent number: 11633094
    Abstract: A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

  • Patent number: 8167798
    Abstract: A device for expanding an elongate opening formed in a skin layer of a patient includes a first arm for engaging one side of the opening and a second arm for engaging the other side of the opening. The device further includes a spreader mechanism, coupled to at least one of the first and second arms, to move the at least one of the first and second arms to widen the opening. The at least one arm is configured to move between a retracted position in which the at least one arm is positioned next to the other arm and an extended position in which the at least one arm is extended to expand the opening. Other embodiments of the device as well as methods for performing a medical procedure are further disclosed.

  • Patent number: 8118738
    Abstract: A vaginal speculum includes a frame and a first handle assembly pivotally mounted to the frame. The frame defines an opening between a first blade that is attachable to the frame and a second blade that is attachable to the frame opposite of the first blade, and a hinge assembly configured to flex the frame to selectively change a size of the opening. The first handle assembly includes a lever portion and a blade portion coupled to the lever portion. The blades have a proximal end attachable to the blade portion and a distal end portion spaced from the proximal end. When in a first collapsed insertion state, the hinge assembly collapses the frame and the first blade contacts the second blade. When in a second deployed state the hinge assembly expands the frame and the first blade is spaced apart from the second blade.

  • Patent number: 8092488
    Abstract: An improved bone retractor tool includes a pair of arms pivotably connected to one in a pliers-like configuration and a pair of tissue engagement plates each having forward and rearward portions, each of the pair of tissue engagement plates mounted on the upper end of one of the pair of arms and extending generally parallel with one another when the pair of arms are in closed position. Forward bone engagement spikes are mounted on and extend forwards from the forward portions of the tissue engagement plates. A releasable securement mechanism is mounted on the pair of arms for releasably retaining the pair of arms in a selected position relative to one another, and a tensioning device is mounted on the pair of arms for tensioning the lower ends away from one another thereby forcing the pair of tissue engagement plates towards one another upon the securement mechanism being released.

  • Patent number: 8062217
    Abstract: Disclosed herein are various embodiments that related to a surgical retractor. In certain embodiments, the retractor may include a blade holder with a single blade tilting mechanism capable of adjusting the angle of a plurality of pivoting blades relative to the blade holder. In certain embodiments, the adjustment occurs from the proximal face or top of the retractor. In other embodiments, blade supports are used to couple the blade holder to a variety of removable blades of different lengths. In certain embodiments, the blades may be a translucent material capable of transmitting light from a proximal portion of the blade to a distal portion. In some embodiments, the distance between the blade holder and the removable blades may be adjusted.

  • Patent number: 8043212
    Abstract: A method for providing treatment at or near a cervical region of the spine of a patient is provided. An incision is formed in the skin of a patient above the cervical region. An elongate body is inserted into the patient through the incision, the elongate body having a distal portion, a proximal portion, an outer surface, and an inner surface, the inner surface defining a passage extending through the elongate body. The elongate body is advanced until a distal end thereof resides at or near the cervical region of the spine. The size of the passage in the distal portion is increased relative to the size of the proximal portion.

  • Patent number: 7985221
    Abstract: An external fixator for treating a fracture of a long bone has six extension arms which are extendable out of and retractable into a main body. The six extension arms are arranged into two sets of three out opposing sides of the main body, with each set of three extension arms being able to support a fixation ring. Each extension arm is pivotable at a joint and extendable so as to allow the ring to be set at a wide range of angular positions relative to the main body. The three extension arms and the ring each define a wrap angle about the axis of the long bone being treated. The longitudinal position of each extension arm can be changed either with a coarse adjustment capability or with a fine adjustment capability, with the coarse adjustment capability being through rotation of a thumb wheel.

  • Publication number: 20110160540
    Abstract: A vaginal speculum is provided that has an upper arm with a handle and jaw. A cross-sectional shape of a longitudinally extending portion may be constant along its entire longitudinal length so that the height of the portion is likewise constant along its length. Right and left side flanges may extend downward from the longitudinally extending portion and a tip of the jaw. The distance between the outer surfaces of the right and left side flanges in the lateral direction may be constant along their entire lengths in the longitudinal direction. A lower arm with a jaw and handle may be included and arranged with the upper arm so that their relative position to one another can be modified.

  • Patent number: 7850608
    Abstract: A minimal incision maximal access system allows for maximum desirable work space exposure within the incision along with maximum access to the operative field utilizing a minimum incision as small as the width of the working tube. Instead of multiple insertions of dilating tubes the design is a streamlined single entry device to avoid repetitive skin surface entry. The system offers the capability to expand to optimum exposure size for the surgery utilizing retractors depending from a bi-hinged frame having internal or external controls to control the angle and separation of the retractors. Interchangeable retractor blades can be attached to the frame. At least one retractor blade is independently controlled.
