项目摘要

A new arthroscope, which has a channel for endscopic surgery of the temporomandibular joint (TMJ), and the instruments needed for this surgery have been recently developed. In the past, two techniques (single puncture and double puncture techniques) were used for endoscopic surgery of TMJ.The single puncture technique can be subdivided into the blind technique and the direct visual technique. The blind technique has a disadvantage in that a precise surgery is not possible. The direct visual technique has disadvantage in that because the arthroscopic lens systems used for this technique need a channel for surgery, and the diameter of this endoscope is thick (3.8X2.0 mm) and causes a relatively high surgical damages. The double puncture technique has a disadvantage in that much skill is needed for maneuvering the surgical instruments (inserted through a separate cannula) into the visual field of the arthroscope inserted through another cannula. Following the recent development of a very small diameter fiberscope with a high pixel number (15,000 pixel), we have recently developed a new arthroscope, designed to resolve the previous problems. This arthroscope combines a fiberscope with a surgical channel (phi1.1mm). The length and diameter (phi2.9mm) of this fiberscope cannula are identical to those of the most frequently used Striker's arthroscope cannula. At the same time, we have developed the instruments for use in surgery that would fit through the surgical channel of this arthroscope (probe, forceps, knives, cautery knives, etc.). The use of this artroscope causes less surgical damage and allows more reliable arthroscopic surgery, when compared with conventional techniques.

最近开发出了一种新型关节镜，该关节镜具有用于颞下颌关节（TMJ）内窥镜手术的通道以及该手术所需的器械。过去，颞下颌关节内镜手术采用两种技术（单穿刺技术和双穿刺技术）。单穿刺技术又可细分为盲法技术和直视技术。盲法手术的缺点是不可能进行精确的手术。直视技术的缺点在于，由于该技术使用的关节镜系统需要手术通道，且该内窥镜的直径较粗(3.8X2.0mm)，手术损伤较大。双穿刺技术的缺点在于，需要很高的技巧来将手术器械（通过单独的插管插入）操纵到通过另一个插管插入的关节镜的视野中。继最近开发出具有高像素数（15,000像素）的极小直径纤维镜之后，我们最近又开发了一种新型关节镜，旨在解决以前的问题。该关节镜将纤维镜与手术通道（phi1.1mm）结合在一起。该纤维镜插管的长度和直径 (phi2.9mm) 与最常用的 Striker 关节镜插管相同。同时，我们开发了适合通过该关节镜手术通道的手术器械（探头、镊子、手术刀、烧灼刀等）。与传统技术相比，使用这种关节镜可以减少手术损伤，并且可以进行更可靠的关节镜手术。
