| 20080214899 | CRANK RETRACTOR HANDLE - The present invention relates to an apparatus for adapting a non-cylindrical serrated surgical retractor blade handle to the cylindrical bore of a universal joint. The apparatus includes an adaptor housing having a retractor handle passageway, at least a portion of the retractor handle passageway being configured to receive the slideable insertion of a non-cylindrical retractor blade handle. The adaptor housing is configured for rotational insertion into the cylindrical bore of a clamping member, thereby allowing the adaptor housing, the non-cylindrical retractor blade handle, and an attached retractor blade, to rotate about the longitudinal axis of the non-cylindrical retractor blade handle. In the illustrated embodiment, a pawl mechanism is connected to the adaptor housing and configured for automatic engagement with at least one of a plurality of serrations that are located on the non-cylindrical retractor blade handle, thereby allowing for the efficient adjustment and automatic locking of the linear position of the non-cylindrical retractor blade handle relative to the operative site. | 09-04-2008 |
| 20090275804 | Hinged Retractor With Sheath - A hinged retractor includes a distal portion adapted to be located inside the body of a patient during a surgical procedure and a proximal portion adapted to be closer to the surgeon during a surgical procedure. The hinged retractor includes a first side including a first blade and a second side including a second blade. The second side is joined to the first side proximate to a distal end of the hinged retractor. The hinged retractor includes a pivot proximate to the distal end. The hinged retractor is movable between a closed position and an open position, wherein a distance between a proximal portion of the first and second blades increases more than a distance between a distal portion of the first and second blades when the hinged retractor is moved from the closed position to the open position. | 11-05-2009 |
| 20090287062 | Adjustable Rail Clamp - An adjustable surgical retractor system for clamping system to an operating table. The clamping mechanism includes an upper jaw, lower jaw, a drive member, an adjustable frame support post and releasable locking mechanism for adjusting the height of the surgical retracting frame. The releasable locking mechanism can be a mechanism that includes a sleeve in close sliding relationship to the upper portion of lower jaw member. The upper portion of the lower jaw has a plurality of sockets for receipt of a plurality of balls. The sleeve can have a first position which positions an internal shoulder in alignment with the sockets and urges the balls into engagement with circumferential grooves in post member to lock the post at desired height. In a second position, an internal groove in the sleeve can align with the sockets to allow the balls to move partially out of the sockets and out of engagement with the groove in the post so that the post can be longitudinally adjusted relative to the clamping mechanism. | 11-19-2009 |
| 20100030033 | SURGICAL LIGHT APPARATUS - A surgical light apparatus for illuminating a surgical site. The light apparatus may include a light housing, fiber optical cable, a sheath, and a cable connector. The fiber optical cable may be comprised of a bundle of fiber optical cables that have distal and proximate ends. The proximate end may be operably connected to the cable connector, and oriented to receive light emitted from a light source. The distal end of the fiber optical cable may be operably connected to the light housing. The light housing may include a main body and a cover, which either individually, or in combination with each other, provides an outlet at which the distal ends of the fiber optical cables may be dispersed. The light housing may include, or be operably connected to, an attachment mechanism that may attach the surgical light apparatus to a surgical instrument, for example a retractor blade. | 02-04-2010 |
| 20100185060 | Low Profile Surgical Retractor - Certain embodiments of the present invention provide a retractor clamp for a low profile retractor system including a spreader including first and second arms joined by a cross-bar, wherein the first and second arms define an arm level. The retractor clamp includes a gripping assembly, a main body, an extension arm, a retractor blade arm, and a securement assembly. The gripping assembly is sized and adapted to engage at least one of the first arm, second arm, and cross-bar, wherein the retractor clamp is movably and securably joined along the at least one of the first arm, second arm, and cross-bar at substantially the arm level. The retractor blade arm is joined to the main body by the extension arm, and is positioned at a retractor blade arm level above the arm level. The retractor blade arm is sized and adapted to accept a blade clamp for securing a retractor blade thereto. The securement assembly includes an adjustment member sized and adapted to be accessible by an operator at an elevation substantially at the arm level. The securement assembly is operatively connected to the gripping assembly. | 07-22-2010 |
| 20100217089 | Surgical Retractor with Locking Blade - Certain embodiments provide surgical retractors that include an arm and a blade, the arm including an opening and a first notched surface comprising a plurality of notches that extend radially outward from the opening, the blade including a nipple and a second notched surface comprising a plurality of notches that extend radially outward from the nipple. Attaching the blade to the arm such that the notched surfaces mate can secure the blade relative to the arm such that the blade cannot swivel radially about the opening. Certain embodiments provide methods for securing a retractor blade that can include inserting a nipple on a retractor blade into an opening and mating a first notched surface comprising a plurality of notches that extend radially outward from the opening with a second notched surface comprising a plurality of notches that extend radially outward from the nipple. | 08-26-2010 |
| 20100305407 | Malleable Port Retractor - A port retractor includes malleable leaves that may be bent outwardly to an open position from a closed position. The port retractor includes a body having a cross-section defining a substantially closed area, with the leaves extending therefrom. The leaves extend from the body at an angle when bent to the open position. Further, the port retractor may include opposed pairs of leaves. | 12-02-2010 |
| 20110137130 | Posterior Lumbar Retractor System - A retractor system includes a frame and first and second retractor blades. The frame includes first and second securement features. At least one of the first and second securement features is movable with respect to the frame when the at least one of the first and second securement features is mounted to the frame. The first and second retractor blades each have a distal portion and a proximal portion. The proximal portions of the first and second retractor blades are configured to be secured proximate to the first and second securement features respectively, such that the first and second retractor blades may be positioned in a first position wherein the first and second retractor blades are laterally opposed. A movement of the at least one securement feature that is movable with respect the frame adjusts the angle of at least one of the retractor blades, wherein the at least one of the retractor blades may be adjusted between a first angle less than 90 degrees to horizontal and second angle greater than 90 degrees to horizontal. | 06-09-2011 |
