We have been studying applicational arthroscopic surgery for temporomandibular joint diseases since 1974. And through this study we have develoved a newly designed system of surgical arthroscopy.this prototype has an external diameter of 1.7 mm. The angle of vision is 60゜ in air and 45゜ in water. The effective length with the outer cannula set on is either 90 mm or 50 mm. The most important achievement of this device is that it enables the usage of two types of different-sized outer cannula in the same arthroscope: a round single-lumen outer cannula (external diameter 2.0 mm) and an oval double-lumen outer cannula (3.8x 2.0). The single-lumen outer cannula can easily be replaced with the double-lumen outer cannula by using an internal guiding needle. this device can be used not only for diagnostic arthroscopy but also for arthroscopic surgery.In particular, it has a hole for surgical device insertion which enable parallel insertion of device. This makes it easy to always observe the advancing edge of surgicaldevice and the manipvlation can therefore be greatly improved.

自1974年以来，我们一直在研究颞下颌关节疾病的应用关节镜手术。通过本课题的研究，我们研制了一种新型的关节镜手术系统，该系统外径为1.7mm，在空气中的视角为60 °，在水中的视角为45 °。外套管的有效长度为90 mm或50 mm。该器械最重要的成就是，它可以在同一关节镜中使用两种不同尺寸的外套管：圆形单腔外套管（外径2.0 mm）和椭圆形双腔外套管（3.8x 2.0）。通过使用内部引导针，单腔外套管可以很容易地更换为双腔外套管。该装置不仅可用于诊断性关节镜检查，而且可用于关节镜手术。特别地，它具有用于手术装置插入的孔，该孔能够使装置平行插入。这使得始终容易观察到外科器械的前进边缘，因此可以大大改善操作。
