Patent ID: 7878972

Claim:
An objective head for an endoscope, wherein the objective head is located at a distal end portion of the endoscope, comprising: a lens cell; a lens cell holder, the lens cell at least partially removably coupled with at least a portion of the lens cell holder; wherein at least a portion of the lens cell and at least a portion of the lens cell holder are coupled in nesting, threadless frictional engagement defining a friction interface therebetween; wherein the portions of the lens cell and lens cell holder complement each other in size and shape so as to substantially prevent movement between the lens cell and the lens cell holder during normal handling of the endoscope, while allowing for disengagement without the need for a permanent adhesive requiring elevated temperatures to break; and wherein the nesting, threadless frictional engagement allows the lens cell to be removable from the lens cell holder at a distal end of the objective head.
