Embodiment Construction

[0023]The novel endoscope tube includes an endoscope tube 3 equipped with a manipulation structure 2 and a connecting branch pipe. The air channel 15 and the air valve 17 on the control structure 2 or in the pedal connect the working pressure source with the hole 21 opening to the bore of the seal 13 which is connected to the bore 14 of the sleeve 22 . The length and diameter of the distal portion of the sleeve 22 are equivalent to the non-turning portion of the introvert 23 , and the proximal portion is equivalent to the pressed spring 10 . The turning head 12 of the introvert 23 is fixed on the sleeve 22 with the ring 16 . The introvert 23 has a narrowed portion and a dilated portion 24 , as well as a gap 25 with a distal protective membrane 26 . Where the tip of the distal protective membrane 26 and the proximal protective membrane 27 and the tube 3 fit, there is a portion 28 for interconnection and sealing. A seal 29 on the head 7 of the introvert 23 separates the bore 1...

Abstract

The present invention pertains to the field of medicine and may be used for moving endoscope pipe and carrying out biopsies in the serpiginous channels. This invention more precisely relates to an endoscope that comprises an invagination device in the shape of a compact cylinder, which is a thin-wall pipe turning in a wrong side out fashion under the pressure of air or liquid. The difference between the endoscope of the present invention and the known endoscope is that the invagination device of the present invention is formed is a fashion of firmness hollow short cylinder installed on the distal end of the endoscope pipe and a gap is provided between the short cylinder and the endoscope. The cylinder of the invagination device, the spring for moving the invagination device, sealing elements, protecting film of the distal end of the endoscope pipe are all installed in the sleeve forming a one-off clamping disk. The endoscope with a one-off clamping disk have a hydraulic power baric machine for moving the endoscope, a hand-motion hydrosystem for bending the distal end of the endoscopic pipe, an extraction / introduction hydrosystem for biopsies clamp. The endoscope further includes a manipulating structure formed in a fashion of pedals parts on the table unit.

Description

technical field [0001] The invention belongs to the technical field of medicine, specifically, colonoscopy and endoscopy, and can also be used in industrial endoscopes. Background technique [0002] Known patent DE3329176 disclosed on November 22, 1984 comprises an endoscopic tube mounted in a reversible tube under liquid pressure, which serves as both a carrier and a Introverter (hereinafter referred to as introverter). The introverter in this device is arranged in parallel long layers one by one relative to a pipe to be transported. The disadvantage of this device is that the layers of the introverter The phenomenon of inconsistent detachment due to the layers "sticking to each other" under air pressure and due to the inevitable entry of air into the middle of a layer in the invagrator. Too early inversion of a layer causes the It is impossible for the layers located above the one layer to participate in the intubation process. [0003] The device according to US Pat. No...
