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. 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 (φ1.1mm). The length and diameter (φ2.9mm) 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.). To evaluate the tissue response after arthroscopic lysis with electrocautery in the temporomandibular joint (TMJ) of sheep histologically and radiologically. Thirteen adult merino sheep, weighting about 60 kg, were used. The instr … More uments used in this study were a newly developed arthroscope with a channel. Electrocautery was inserted into the inner channel and the tip placed directly against the synovial membrane of the posterior pouch and the surface was injured from medial to lateral walls by electrocautery with a power of 125 watts. The tip is then placed against the articular surface of the tuber which was damaged from medial to lateral part with electrocortery until the underlining bone was exposed. At the 2nd, 4th, 8th, 12th week after the initial operation, the sheep were sacrificed by an anesthetic overdose. The specimens were decalcified and sagitally sectioned from lateral to medial for histologic study.At the 4th week after the initial operation, all discs were perforated. At the 12th week after the initial operation, the condylar articular surface was partly denuded in some areas, and part of the surface showed fibrous repair, and the disc was displaced to the anterior portion. These changes were radiographically and histologically similar to advanced osteoarthritis. Is was suggested that an arthroscopic lysis with electrocautery against the synovial membrane of the posterior pouch was induced the osteoarthritic change of sheep TMJ. Less

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）的端距手术渠道，并且该手术所需的仪器已被开发。在最近开发了一个非常小的直径纤维镜（15,000像素）之后，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（φ1.1mm）结合在一起。该纤维镜的长度和直径（φ2.9mm）与最常用的前锋关节镜套管相同。同时，我们开发了用于手术中的仪器，该工具可以通过该关节镜（探针，镊子，刀，刀刀等）的手术通道。在组织学和放射学上，用电疗法裂解关节镜裂解后的组织反应。使用了13只成年美利奴绵羊，使用了约60公斤的重量。在这项研究中使用的工具是一种带有通道的新开发的关节镜。电载体被插入内通道，并直接置于后袋的滑膜上，而表面则通过电动阀从培养基到侧壁受伤，电孔的功率为125瓦。然后将尖端放在块茎的关节表面上，该表面从培养基到外侧损坏，直到暴露于下划线的骨骼。在初次手术后的第二，第4、8、12周，绵羊被麻醉过量牺牲。这些规格是从侧向到培养基的，以进行组织学研究的脱钙和萨基式切片。在初始操作后的第4周，所有椎间盘均已穿孔。在初次操作后的第12周，在某些区域部分剥去了孔的关节表面，部分表面显示了纤维修复，并且椎间盘移至前部。这些变化在放射线学和组织学上与晚期骨关节炎相似。被提出，用电言疗法的关节裂解诱发了绵羊TMJ的骨关节炎变化。较少的
