[Subcutaneous operation and examination under the universal endoscope].

Endoscopes are mainly used to study the internal structures of organs and tissues with inherent space. These include the gastrointestinal tract, abdominal space and joint space. The standard endoscope, however, cannot be used to evaluate tissues without such space. We have invented a new type of operation tube to be used with the arthroscope. This combination enables us to study subcutaneous soft tissues without inherent space. Our new device is a powerful tool to be used for evaluation of subcutaneous soft tissues in any part of the body. Surgical procedures can also be carried out with this device. Areas of future applications of our device will be extremely wide including orthopaedic surgery, plastic surgery and general surgery. The presentation will discuss the procedure for utilizing this new instrument.
