Arthroscope Set
Arthroscope set consists of Arthroscope, Cannula and Obturator and/or Trocar. As mentioned in the first chapter, Arthroscope is a telescope that is used to look inside the joints of body without actually opening them. Arthroscope is made up of three distinct parts. The first part is the eye-piece, second is the shaft and the third is the tip. Eye-piece is the part through which a surgeon views the interiors of the joint, shaft, the longest part of the Scope, has a rod-like appearance and performs the function of transmitting and focussing the image on the eye-piece. The last part of the Scope, tip, performs the most essential function of gathering the image from inside the joint, or to put it more technically, it is the tip that gathers the light reflected from anatomy and focuses it onto the transmitting medium inside the shaft of the scope. Apart from this, the modern day scopes are manufactured so as to accommodate transmission of light from the source to the joint. This is accomplished by making the scope in concentric geometry. That is, the scopes are made like one cylinder over another cylinder. The space in between the outer and inner cylinder is occupied by fibres that carry the light. At the tip, there is a window from where the light is thrown onto the anatomy. The light reflected from the anatomy is collected by the tip of the scope and passed onto shaft for transmission of image to the eye-piece through the inner cylinder. It is obvious that the scope is made up of only optic components; components that handle only light and information contained in that light. There is no electronics involved.
