Definitions

  • the present invention relates to the construction of an endoscope, particularly having means for providing for the irrigation of the body part and for simultaneous direct viewing of the body part.
  • an endoscope or the like comprising a shaft, having a hollow head located at its proximal end and radially directed inlet and outlet openings for passing an irrigating fluid.
  • the head is provided with an eye-piece located along the axis of the shaft at the proximal end.
  • a transparent body is arranged between the eyepiece and the openings substantially filling the space between the openings. The provision of the transparent body acts to prevent formation of air bubbles in the head while permitting direct viewing through the eyepiece.
  • the transparent body is made of rectangular cross sections.
  • the transparent body replaces and makes it unnecessary to use a shutter or closeable window.
  • FIG. I is a side elevational view of an endoscope; embodying the present invention.
  • FIG. 2 is a view partially sectioned of the endoscope of FIG. 1 turned about its axis.
  • an endoscope insert adapted to be inserted in the patients body via a sheath or other tubular inserting device is shown.
  • the insert comprises tubular hollow shaft 1 having an outlet opening 2 for discharging irrigation fluid and an inlet opening 3 for supplying liquid thereto.
  • the inlet and outlet openings are located at the same level along the shaft 1.
  • Mounted on the proximal end of the shaft is a hollow head 4 on which is located an eyepiece 5 closing the proximal end of the head 4.
  • a lightconductor 6 such as a glass, Lucite or similar rod.
  • the light conductor 6 is connected to a neon lamp or other cool light source 7 powered in the conventional manner.
  • the eyepiece 5 is provided with an elongated depending transparent body 8 extending downwardly to the level of the outlet and inlet openings 2 and 3.
  • the transparent body extends in the hollow interior between the eye-piece 5 and the outlet-inlet openings 2 and 3, replacing the previously known shutter lens or window.
  • the distal end of the transparent body 8 fills the cross section of the upper end of the shaft 1 so that no air bubble can settle and disturb the view through the eye-piece 5. Furthermore, the distal end of the body 8 is continuously rinsed by the incoming irrigation fluid as well as the outgoing fluid by operation of valves 9 and 10 so that particles, air bubbles and other impurities are always removed.
  • the transparent body is preferably made of glass and is bar-like being rectangular or square in cross section. While glass is preferred, it may be replaced by suitable plastics such as Lucite or other optically suitable materials.
  • the transparent body and the optical eye-piece can be made unitarily, integral or even separately of parts which may or may not be joined. The best optical results should obtain for the type of construction actu ally used.
  • the present device eliminates the shutter window and allows direct viewing when irrigation is being carried out. Furthermore, the present invention can be applied without otherwise changing the cystoscope and without the need for rearrangement of any of its other parts.
  • An endoscope or the like comprising a hollow shaft having a hollow head located at its proximal end and radially directed inlet and outlet openings located at a common level distally of said hollow head for the supply and removal of fluid to said shaft, an eyepiece body is rectangular in cross section.
