Method for manufacture of a tip part and a tip part for an endoscope

A method for manufacture of a tip part for an endoscope, said method comprising:

• providing a camera assembly including an image sensor, a lens barrel positioned at a distal end of the camera assembly, at least one light source with a light emitting surface configured to emit light distally, and a circuit board positioned at a proximal end of the camera assembly;
• providing an exterior housing of the tip part, the exterior housing comprising a circumferential wall and a distal end wall, the circumferential wall and the distal end wall defining an internal volume of the exterior housing, the distal end wall being integral with the circumferential wall and having an opening, the distal end wall including an interior surface configured for transferring light received from the at least one light source therethrough and a proximal portion extending proximally from the interior surface;
• inserting the lens barrel of the camera assembly into the interior volume of the exterior housing so that a distal end of the lens barrel extends into the opening, with the proximal portion extending proximally from the internal surface is adjacent the lens barrel, and so that a gap is provided between the opening and the lens barrel along a periphery of the lens barrel and extending further proximally than the interior surface of the distal wall, the gap further extending between the proximal portion and the periphery of the lens barrel, a radial extent of the gap decreasing in a direction towards the internal volume of the exterior housing;
• injecting an adhesive into the gap, wherein the proximal portion comprises a barrel-facing surface;
• and
• allowing or causing the adhesive to harden so as to adhere the lens barrel to the distal end wall of the exterior housing, wherein the adhesive adheres the barrel-facing surface of the proximal portion and the periphery of the lens barrel.
