Description

Guider for fiber bronchoscope

Technical Field

The invention belongs to the field of medical instruments in the department of respiration, and particularly relates to a guider for a fiber bronchoscope.

Background

The bronchoscope is a medical instrument which is placed in the lower respiratory tract of a patient through the mouth or the nose, is used for observing the pathological changes of lung lobes, segments and subsegments of bronchus, biopsy sampling, bacteriological examination and cytological examination, and can be used for photographing, teaching and dynamic recording in cooperation with a TV system. The biopsy sampling accessory connected can assist in finding early lesions and can be used for internal and external surgical operations such as polyp removal and the like. It is suitable for the research of bronchial and pulmonary diseases and the operation of postoperative examination.

The german larynx doctor Gustav Killian performed the first bronchoscopy in 1897. Killian uses a rigid bronchoscope to remove the pig bone. This process is performed while the patient is awake and cocaine is administered to the patient as a local anesthetic. From this time to the 70's of the 20 th century, rigid bronchoscopes were used as irreplaceable bronchoscopes. Chevalier Jackson improved a rigid bronchoscope for the 20 th century and was used to visualize tracheal and main bronchial lesions. The uk laryngis physician Victor Negus, who worked with Jackson, improved the design of the endoscope, including later "Negus bronchoscopes". Shigeto Ikeda invented a soft bronchoscope in 1966. Soft bronchoscopes initially used fiber optic bundles, requiring an external light source for illumination. These scopes have an outer diameter of about 5mm to 6mm and are capable of bending 180 degrees and extending 120 degrees to allow access to the lobes and segmental bronchi.

A fiberoptic bronchoscope consists of an elongated, flexible catheter that includes several components: an illumination device designed for the peripheral distant region of the bronchoscope tip; an image capture system designed for transmitting real-time video and having the capability of taking still photographs, connected to an external light source through a flexible optical fiber; a working channel, wherein diagnostic instruments, therapeutic instruments and medicaments can be inserted or slowly infused into the working channel. The distal end of the bronchoscope can be manipulated in one plane by flipping the handle up and down, and in another plane by rotating the handle of the bronchoscope left and right to reach the intended target.

When the fiber bronchoscope is used for oral fiber bronchoscope tracheal intubation, because the inserted optical cable is soft and is not easy to control, particularly, when a patient is under general anesthesia, muscles are relaxed, the tongue root falls down, an oral cavity channel is narrow, so that the operation becomes more difficult, the intubation time is obviously prolonged, the hypoxia time of the patient is correspondingly prolonged, and if the hypoxia time of the patient exceeds 5 minutes, cerebral cell edema can be generated, postoperative cognitive dysfunction can be caused, and even serious patients can die.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a guider for a fiber bronchoscope.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a guider for a fiber bronchoscope comprises a fixer, a guide tube, an extension tube and an extension guide sleeve, wherein one end part of the fixer is connected with one port of the guide tube; the light guide rod of the guide tube light supply rod and the inserted optical cable of the fiber bronchoscope can extend into and penetrate through the fixator from the groove length direction of the guide tube; the top end of the telescopic pipe is connected with the other end of the fixer, the tail end of the telescopic pipe extends into the inner cavity of the telescopic guide sleeve, the tail end of the telescopic guide sleeve is connected with the end of the fiberbronchoscope body, and the light guide rod of the light rod and the inserted optical cable of the fiberbronchoscope sequentially penetrate through the telescopic guide sleeve, the telescopic pipe and the guide pipe and then are exposed out of the guide pipe.

Furthermore, the fixer is provided with a guide opening groove and a guide hole, and the guide opening groove and the guide hole are arranged in parallel.

Furthermore, the guiding tube is provided with two parallel pipelines, the whole cross section of the guiding tube is an 8-shaped channel, a side groove is formed in the side wall of the first pipeline, the second pipeline is a complete channel containing cavity, the first pipeline is communicated with the guiding open groove, the side groove is communicated with an opening in the depth direction of the guiding open groove, and the second pipeline is communicated with the guiding hole.

Furthermore, the width of the opening of the side groove and the guide opening groove is larger than the diameter of the insertion optical cable, so that the insertion optical cable of the fiber bronchoscope can be conveniently separated from the fixer and the guide tube.

Further, the guide tube is in a J-shaped shape.

Has the advantages that: the invention has simple structure, realizes the rapid guide of the inserted optical cable of the fiber bronchoscope to reach the glottis, shortens the intubation time, improves the success rate and ensures the safety of patients.
