Abstract

A suture fixation arthroscope apparatus of the temporomandibular joint (TMJ) disk comprises a first suture needle and a first inner core, a second suture needle and a second inner core, and a third suture needle. The tail ends of the first and second suture needles are connected with a big handle via a valve panel, a vertical groove is opened towards the center of a circle of the surface of the big handle, a horizontal groove which is the same size as the vertical groove is vertically set at the place of the big handle connecting the valve panel. The first inner core includes a seamless tube and a top welded with wire snares, the second inner core includes a seamless tube and a top welded with a crochet hook, the radian near the tails of the first and second inner cores is 90 degrees, a small handle is connected at the tails. The first and second inner cores can pass through the vertical groove of the big handle of the first and second suture needles respectively, the corner of the 90 degrees tail is able to lock rightwards or leftwards at the horizontal groove, the wire snare or the crochet hook at the top of inner cores are able to come out from the top of the suture needles.

Claims
