Rigid Endoscope Parts and Working Principle

The Application of Rigid Endoscope Parts

The application of rigid endoscope parts is widespread in the medical field both domestically and internationally. Many departments in our hospital, such as the Urology Department with kidney mirrors and cystoscopes; the Gynecology Department with hysteroscopes and laparoscopes; the ENT Department with sinus scopes; and the Orthopedics Department with foraminal mirrors, shoulder arthroscopes, knee arthroscopes, and wrist arthroscopes, all use these rigid endoscope parts for examinations and surgeries.

The rigid endoscope parts from Sihanmed provide clear images, simple operation, and flexible and convenient use. Doctors can directly observe the area of concern to examine and diagnose patients. However, as the frequency of use for rigid endoscope parts and endoscope systems increases, the likelihood of malfunctions in these rigid endoscope parts and their supporting equipment also rises.

The most common failures include image malfunctions due to faults in the rigid endoscope parts' imaging system, light failures caused by faults in the light source unit, and damage to the rigid lens due to improper handling by operators. Moreover, the repair costs for these failures are quite high. Hospitals strive to minimize failures of rigid endoscope parts and endoscopic systems to enhance equipment efficiency.

Working Principle of Sihanmed Rigid Endoscope Parts

There are various types of rigid endoscope parts. To meet different surgical or examination requirements, Sihanmed's rigid endoscope parts have slight differences in shape, length, angle, and thickness. However, the basic imaging principle remains the same. Rigid endoscope parts display the lesion image to the operator or imaging system through a complex optical imaging system and illumination system.

The  working principle: The tissue to be observed forms an image through the objective lens. According to inspection requirements, different angled prisms within the objective lens group may be needed to achieve angular changes. After forming the image, the objective lens transfers the inverted image to an erect image through a relay lens and then to the eyepiece, where it gets magnified into an observable image. The illumination system's principle is to transfer light from the light source unit to the front end of the endoscope via optical fibers, illuminating the tissue to be observed.
