发明名称 Surgical retractor adjustable mounting apparatus
摘要 An arcuate frame is sized to fit concentrically at a spaced distance about the head. Retractors, retaining the mouth and lips in open position for vertical and lateral exposure during mouth and jaw surgery, are adjustably suspended from the frame by an adjustable universal connector. The frame is mounted on an upstanding support from the operating table by connecting means providing adjustability thereof for universal spacial orientation. One or more beaded chains control the position and tension on each of the retractors, other than the tongue retractor, by releasably engaging anchors carried by connectors which are adjustably positioned along the frame. A single thumb screw secures and releases each anchor for simultaneous adjustment along the frame and at right angles toward and away from the frame. Other surgical applications requiring adjustable retractors are anticipated for the device.
