The minimally invasive procedure performs many conditions of diagnosing and treating with the help of a surgical telescope. There are two main types of surgical scope (Rigid & Flexible). Flexible endoscopes are needed to thoroughly examine the depths of tubular structures that turn corners (e.g.intestine, bronchial tree, and male canine urethra), but rigid endoscopes are more convenient for examining nontubular structures such as the abdominal cavity, thoracic cavity, or joint spaces, etc. A surgical telescope helps in providing a clear visualization of the infected area which is inside the body. Rigid endoscopes are made of metal tubes that contain a series of high-resolution optical glass rod lenses, and the light channel to allow visualization out of the axis of the telescope and increase the FOV (Field of view) by rotating the instrument. Direct visualization of a diseased area inside the body can be achieved by using a telescope through a small incision in the skin. Rigid endoscopes are commonly used in urology, gynecology, ENT, arthroscopy, endoscopic spine surgery, and general surgery. IMPORTANCE…
