Fabrication Method Of Plane Bearing Endoscope

Endoscope is a kind of medical instrument commonly used in the existing technology. At the same time, it is also the most delicate medical instrument in the domestic medical field. The endoscope comprises an insertion part for direct insertion into the body, a bending part that can be bent at will, and a handle part for manual operation of the control part. The handle part comprises a handle body and an inner and outer runner group arranged on the handle body. The inner and outer wheel group comprises a wheel shaft mounted in the main body of the handle, on which an inner wheel and an outer wheel are respectively mounted. When rotating, because the inner wheel and the outer wheel are in surface contact, it is easy to cause friction at the contact point between the inner wheel and the outer wheel, resulting in greater interference between the inner wheel and the outer wheel
