Embodiment Construction

[0011] The structure of the duodenoscope is described as follows in conjunction with the accompanying drawings: figure 1 As shown, the side of the end of the duodenoscope is composed of an observation system 1, an illumination system 2, a forceps lifter 3 and a biopsy forceps 4. Due to the existing duodenoscope figure 1 As shown in the steel wire rope gap 5, the movement of the steel wire rope in the tunnel makes the endoscope easy to be polluted, and the narrow gap here is limited to the intrusion distance of the disinfectant solution, which causes the bacteria to be unable to be completely killed, making it difficult to completely disinfect. For this reason the present invention improves this unfavorable structure, by figure 2 , image 3 As shown, the rubber bellows 9 is used to fully seal and protect the fine monofilament 8 and the channel 10. One end of the rubber bellows 9 is glued to the fine monofilament, and the other end is glued to the channel. The rubber bellows a...

Abstract

The invention discloses duodenoscope and belongs to the field of medical instruments. An observation system, a lighting system and an operation pipe opening are arranged on the side face of the head end of an insertion portion. A forceps lifter is arranged in the pipe opening and is in sliding connection with a steel wire rope in the axial direction. A gap between the steel wire rope and a pore matched with the steel wire rope is sealed through a rubber bellows. One end of the rubber bellows is bonded to the outside of the steel wire rope, and the other end of the rubber bellows is bonded to the inner wall of the pore matched with the steel wire rope. A fine monofilament is welded to the front end of the steel wire rope and connected with the forceps lifter. By means of the structure of the duodenoscope, the problem of unreliability of sterilization of duodenoscope caused by the fact that pollutants and microorganisms are brought into the duodenoscope in the traction process as a result of the axial gap between the steel wire rope and the pore is solved thoroughly, and huge security assurance is brought to doctors and patients.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a duodenoscope. Background technique [0002] There have been a number of recent deaths in the United States that may have resulted from the use of contaminated duodenoscopes by patients who were infected with drug-resistant bacteria. Most people think that the small parts of the duodenoscope and the complicated structure make it difficult to achieve the standard of disinfection, resulting in infection. [0003] The inventor carefully analyzed the head end structure of the duodenoscope from a professional point of view, and believed that the main source of pollution came from the axial pulling gap between the wire rope of the front end of the insertion part pulling the forceps lifter and its matching hole, allowing the pollutant liquid to enter The inside of the mirror body is not easy to clean and disinfect thoroughly, which becomes a hidden danger. Contents of the inventio...
