摘要
我们一直在研究应用关节镜手术治疗颞下颌关节疾病。下面报道一种新设计的诊断/手术关节镜系统。这个原型机的外径为1.7毫米。视野角度在空中为60度,在水中为45度。外置套管时的有效长度为90mm或50mm。该装置最重要的成就是它能够在同一关节镜中使用两种不同大小的外套管:圆形单通道鞘(外径2.0 mm)和椭圆形双通道鞘(3.8 X 2.0)。通过使用内外导针,可以方便地将单通道护套替换为双通道护套。该装置不仅可用于关节镜诊断,也可用于关节镜手术。特别地,它具有用于手术装置插入的孔,使装置能够平行插入。这样可以方便地随时观察手术器械的前沿,从而大大提高操作水平。
[Newly designed needle scope system for arthroscopic surgery by double-channel sheath method].
We have been studying applicational arthroscopic surgery for temporomandibular joint diseases. Reported below is a newly designed system of diagnostic/operating arthroscopy. This prototype has an external diameter of 1.7 mm. The angle of vision is 60 degrees in air and 45 degrees 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-channel sheath (external diameter 2.0 mm) and an oval double-channel sheath (3.8 X 2.0). The single-channel sheath can easily be replaced with the double-channel sheath by using internal and external guiding needles. 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 enables parallel insertion of device. This makes it easy to always observe the advancing edge of surgical device and the manipulation can therefore be greatly improved.
