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.

最近已经开发了一种新的关节镜，该关节镜具有颞下颌关节（TMJ）的端镜手术通道，并且该手术所需的仪器已被最近开发。过去，使用两种技术（单点穿刺和双穿刺技术）进行TMJ的内窥镜手术。单点刺穿技术可以细分为盲技术和直接视觉技术。盲型技术具有缺点，因为不可能进行精确的手术。直接的视觉技术具有缺点，因为用于此技术的关节镜透镜系统需要一个手术通道，并且该内窥镜的直径厚（3.8x2.0 mm），并造成相对较高的手术损害。双穿刺技术具有缺点，因为将手术仪器（通过单独的套管插入）中的手术器械需要很多技能，然后将通过另一个插管插入关节镜的视野。在最近的直径很小的纤维尺寸（15,000像素）的发展过程中，我们最近开发了一种新的关节镜，旨在解决以前的问题。该关节镜将纤维镜与外科通道（PHI1.1mm）结合在一起。该纤维镜的长度和直径（Phi2.9mm）与最常用的前锋关节镜套管相同。同时，我们开发了适合通过该关节镜（探针，镊子，刀，刀刀等）的手术通道的手术中使用的工具。与常规技术相比，这种静脉镜的使用会导致较少的手术损伤，并允许更可靠的关节镜手术。
