Abstract
A method for manufacture of a tip part for an endoscope including providing a camera assembly, an exterior housing including a circumferential wall enclosing a spacing and a distal end wall integral with the circumferential wall and having an opening; inserting a lens barrel of the camera assembly in the spacing so that a distal end of the lens barrel of the camera assembly extends into the opening, and so that an axially extending adhesive spacing is provided between the opening and the lens barrel along a circumference of the lens barrel, a radial extent of the adhesive spacing gradually being reduced in a direction towards the spacing of the exterior housing; injecting an adhesive into the adhesive spacing; and allowing or causing the adhesive to harden so as to adhere the lens barrel to the distal end wall of the exterior housing.
