    Abstract: A worm gear-worm retractor for an implanted tongue retraction device is provided. The retractor of the present invention includes a control switch capable of adjusting a retraction force of a pull line, a pull line fixing device capable of fixing the pull line, and a casing. The control switch and the pull line fixing device are mounted in the casing, and the control switch is a worm gear-worm structure formed by a worm and a worm gear. Because the control switch adopts the worm gear-worm structure, by rotating the worm, the worm gear can be driven, so that the pull line fixing device connected to the worm gear rotates, thereby tensioning or loosening the pull line to adjust the retraction force of the pull line fixing device. The retractor has advantages of a compact structure, a small size and convenient adjustment.

Besides the possibility of being used in several articulated surgical instruments and robotic systems for surgery or other applications involving remote manipulation, it enables the design of a novel fully mechanical surgical instrument, which offer the advantages of conventional laparoscopy (low cost, tactile feedback, high payload capacity) combined with the advantages of single port surgery (single incision, scarless surgery, navigation through several quadrants of the abdominal cavity) and robotic surgery (greater degrees of freedom, short learning curve, high stiffness, high precision, increased intuition).

  • Publication number: 20130255411
    Abstract: A window regulator assembly having cables for driving one or more lifter plates along rails includes connectors for connecting the ends of cables together. The connectors are connectable together in a ‘use’ position and can be held in a lifter plate in the use position. By having the connectors connect to each other they withstand the tension in the cables when the window regulator assembly is at rest and the lifter plate is only required to withstand the differential tension between first and second cable segments during movement of the lifter plate. This allows the lifter plate to be formed from a relatively lower strength and less expensive material since it is subject to relatively lower stresses than prior art lifter plates.
