Definitions

  • the present invention is directed to a rigid endoscope, and more particularly, to a distal portion of a rigid endoscope and method of assembling same,
  • an autoclavable rigid endoscope typically consists of an inner tubular portion, an outer tubular portion and a composite of epoxy adhesive and optical fibers that fill in spaces in between the inner and outer tubular portions.
  • the outer tube heats up and expands while the inner tube remains cool and does not expand. The difference in expansion results in shearing stresses that cause separation and failure of the epoxy adhesive joint.
  • FIG. 1 is a plan view of a distal end of a distal portion of a 0° rigid endoscope in accordance with a preferred embodiment of the present invention.
  • FIG. 4 is an exploded view of an endoscope window assembly.
  • FIG. 22 is a plan view of the distal end of the distal portion of the 30° rigid endoscope of FIG. 20.

Abstract

La présente invention concerne un endoscope comprenant un diaphragme flexible pour raccorder un tube optique d'endoscope d'un sous-ensemble optique d'endoscope à un corps de scope ayant un cône de lumière. Le diaphragme permet la déviation du tube optique dans la direction axiale pour relâcher la dilatation thermique et les contraintes dans le tube optique pendant la stérilisation. Le diaphragme peut être fourni sous la forme d'une rondelle en acier ondulé ayant un bord circulaire interne qui est soudé autour du tube optique et à l'extrémité proximale de celui-ci, son bord circulaire externe étant soudé à une surface intérieure du corps de scope. En variante, le diaphragme peut être une rondelle en caoutchouc. Le bord circulaire interne du diaphragme est ajusté sur l'extrémité proximale du tube optique et intercalé entre des bague-écrous. Un bord externe du diaphragme est attaché de manière similaire au corps de scope.
