  • Patent number: 9402672
    Abstract: A joint distraction device for use in an arthroscopic surgery is provided. The device has a joint distraction mechanism, situated in between two bone fixation surfaces, and is capable of changing the relative distance between these two surfaces. The force generated by the mechanism should be sufficient to insert bone spikes affixed to the surfaces into bone, as well as distract the joint to create a sufficient enough gap to allow the intended procedure. With the surfaces and spikes engaged to bone at opposite sites of a joint, an increase in distraction force results in an increase in the relative distance results, hence increasing the space within the joint. Embodiments of this invention, compared to fracture table approaches, effectively eliminate the risk of pudendal nerve injury, allow for longer surgical times, and allow for much more controllable joint distraction.

  • Publication number: 20130079711
    Abstract: An endoscope manipulation adapter includes a support frame having a first end configured to be rigidly fixed relative to a handpiece of a flexible endoscope, and a manipulation assembly arranged at a second end of the support frame. The manipulation assembly defines a channel for at least one of a flexible endoscope shaft or a flexible endoscope insertion component to traverse through in an axial direction to assist in manipulating the at least one of the flexible endoscope shaft or the flexible endoscope insertion component during use of the flexible endoscope.
