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适用关节镜手术。通过这项研究，我们开发了一种新设计的手术关节镜检查系统。该原型的外直径为1.7 mm。视角在空气中为60°，水中为45°。外套设置的有效长度为90毫米或50毫米。该设备的最重要成就是，它可以在同一关节镜下使用两种类型的不同大小的外套：圆形的单lumen外套管（外直径2.0 mm）和一个椭圆形的双lumen套管（3.8x 2.0）。单人外套可以通过使用内部引导针很容易地用双lumen外套管代替。该设备不仅可以用于诊断关节镜检查，还可以用于关节镜手术。尤其是具有手术器械插入的孔，可以平行地插入设备。这很容易始终观察外科手术的前进边缘，因此可以大大改善操作。
