The HOPKINS® arthroscopes for TMJ arthroscopy are available in the diameters 1.9 mm and 2.4 mm. Furthermore, 0° or 30° directions of view can be used as desired. The rod lens technology of HOPKINS® arthroscopes ensures particularly high image quality and hence the best possible view. This is particularly helpful in complex arthroscopic microsurgery since the technique requires detailed viewing of internal joint structures. Again, custom-fit obturators allow insertion of the arthroscopy sheaths into the joint space as atraumatically as possible. Additional trocars are positioned to allow insertion of instruments into the joint. A series of instruments, such as grasping forceps, scissors, palpation hooks, sickle knives, and probes, can be used in the joint via trocars. HOPKINS® telescopes are autoclavable and can be stored, cleaned, and sterilized in purpose-designed trays.
