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.

一种新的关节镜，它有一个通道，内窥镜手术的颞下颌关节（TMJ），和仪器所需的这种手术已经开发出来。以往内镜下颞下颌关节手术主要采用单穿刺和双穿刺两种技术，单穿刺技术又可分为盲法和直视法。盲技术的缺点在于不可能进行精确的手术。直视技术的缺点在于，因为用于该技术的关节镜透镜系统需要用于外科手术的通道，并且该内窥镜的直径较厚（3.8 × 2.0 mm），并导致相对较高的外科手术损伤。双穿刺技术的缺点在于，需要很多技巧来操纵手术器械（通过单独的套管插入）进入通过另一套管插入的关节镜的视野。在最近开发出具有高像素数（15，000像素）的非常小直径的纤维内窥镜之后，我们最近开发了一种新的关节内窥镜，旨在解决以前的问题。该关节镜结合了纤维内窥镜和手术通道（φ 1.1mm）。该纤维镜套管的长度和直径（φ 2.9 mm）与最常用的Striker关节镜套管相同。与此同时，我们还开发了手术工具，可通过关节镜的手术通道（探针、镊子、刀、烧灼刀等）。与传统技术相比，使用该关节镜造成的手术损伤更小，并且允许更可靠的关节镜手术。
