摘要： A retractor system includes a retractor arm and a retractor. The retractor arm includes an elongated member and a retractor connector coupled to an end of the elongated member. The retractor includes a neck, a blade extending from a distal end of the neck, and a nipple protruding from a top side of the neck at a position toward a proximal end of the neck. The retractor connector includes a port configured to receive the nipple of the retractor and couple the retractor to the retractor arm via the nipple. The neck includes a handle between the nipple and the blade.

摘要： A clamp for a surgical retractor system. The clamp has a tapered conically shaped washer against and through which clamping force is applied to place the clamp in a clamped position. The clamping force is applied by a cam head connected to a central shaft. A locking pin connects the cam head to the shaft. Apertures are provided in the clamp for receiving rod ends of a surgical retractor. Such apertures are circular and are positioned to be closer to the top and bottom edges of the clamp portion of the clamp than to the end edge of the clamp portion.

摘要： A retractor system may include a mounting assembly, an articulated arm, and a retractor blade. The mounting assembly may include a post and a bed mount. The articulated arm may include arm segments, a retractor connector, and a handle segment. The retractor blade may be attached to the retractor connector. A proximal end of the arm segments may be coupled to the post. A proximal end of the handle segment may be coupled to a distal end of the arm segments. A distal end of the handle segment may be coupled to the retractor connector. The handle segment may include a handle that extends longitudinally along the handle segment.

摘要： A joint clamp for a surgical retractor system includes clamps, a cam bolt, and a cam lever. The cam bolt passes through the clamps. A cam lever comprising a cam head pivotally attached an upper portion the cam bolt to permit rotation between a locked position and an unlocked positions. The joint clamp may include springs which provide a scissors clamp of the clamps with a clip-on feature in which the scissors clamp may clipped-on and clipped-off an object such as a frame member, table post, or retractor handle. The springs may further prevent or reduce a rising movement of the clamps when the cam lever rotates from an unlocked state to a locked state.

摘要： A joint clamp for a surgical retractor system includes clamps, a cam bolt, and a cam lever. The cam bolt passes through the clamps. A cam lever comprising a cam head pivotally attached an upper portion the cam bolt to permit rotation about a pivot axis that is perpendicular to a longitudinal axis of the cam bolt. The cam head includes an outer surface that results in a distance between the pivot axis and an upper surface of the clamps being greater when the cam lever is rotated about the pivot axis to a clamping position than when the cam lever is rotated about the pivot axis to a non-clamping position. The clamping force may be calibrated or set via a cam bolt having an adjustable length and/or via a setting screw.

摘要： A retractor system can include a ring frame and a clamp. The ring frame can include a first ring segment and a second ring segment detachably joined to a first ring segment at a joint. The joint can be contained within a cross section of the ring frame that corresponds to a cutting plane perpendicular to an outer surface of the ring frame. The clamp can include an adjustment screw and a first set of jaws and a second set of jaws. The first set of jaws and second set of jaws can define a first aperture configured to receive the ring frame. Rotation of the adjustment screw in a tightening direction can cause the first set of jaws to engage the outer surface of the ring frame and apply a first clamping force to the outer surface of the ring frame received by the first aperture.

摘要： A surgical retraction system includes a frame and a universal joint coupled to the frame. A handle adaptor secures a surgical retractor to the frame via the universal joint. The handle adaptor includes an extension arm, a hinge, and a clamp. The extension arm comprises an elongated member having a proximal end and a distal end. The elongated member is secured to the frame via the universal joint. The hinge is attached to the distal end of the extension arm. The clamp is attached to the hinge and is configured to receive and retain a handle of a surgical retractor.

摘要： A physical retractor apparatus and method for retracting anatomy during surgery wherein the apparatus includes a handle rod, a body portion, a retractor blade and a mechanism which allows the retractor blade to be angularly adjusted, and secured, to one of any number of angular positions. The retractor blade may be first manually positioned to a gross angular position and thereafter fine tuned in angular position. The adjustment mechanism includes a pair of arms forced together to contract about a pivot pin to set an angular position and a threaded screw device which is rotatable to adjust further the angular position.
