【product】Bronchoscopy

- May 07, 2018 -

Bronchoscopes are suitable for observing bronchial lesions in the lobes, segments, and subsegments. Biopsy sampling, bacteriology, cytology, and TV systems can be used for photography, teaching, and dynamic recording. The bronchoscope is attached with a biopsy sampling mechanism, which can help detect early lesions, and can perform in vivo surgery such as polypectomy. For bronchial and pulmonary diseases, postoperative examinations, etc. are a good precision instrument.

basic concept

The bronchoscopy was performed using a bronchoscope with a diameter of about 0.6 cm. After local anesthesia of the throat was performed, (a) was placed in the oral cavity or (b) was placed in the nasal cavity or (c) was placed in a tracheostomy.

classification

(A) Hard bronchoscope: It is a slender hollow tube mirror made of metal. The distal end is a slanted opening. The edge is smooth and blunt. It is easy to insert the trachea without damaging the mucous membrane. There is a mirror handle and a distal ramp shape at the proximal end. The opposite direction of the opening is not only for the handpiece but also the direction of the opening. There are three main types: Jackson, Negus, and bronchoscopy with Hopkins endoscopy.

(b) Soft bronchoscopes:

There are two main types: fiberbronchoscopes and electronic bronchoscopes 

Range of use

The scope of use of bronchoscopy can be divided into three categories:

(I) Diagnostic indications: (A) Hemoporation of unexplained causes, unexplained patients with chronic cough, schizophrenia with unexplained causes, and unresolved causes of hyperthyroidism. (B) The diagnosis and staging of lung cancer patients are based on bronchoscopy for tissue diagnosis. (C) Diagnosis of benign bronchial lesions: acute or chronic bronchitis, bronchial tuberculosis, respiratory inhalation injury, tracheal or bronchial stenosis, suspected bronchial esophageal fistulas. (D) Diagnosis of diffuse lung disease.

(b) indications for treatment: (A) take foreign body in the trachea, (B) extract tracheal secretions and blood clots. (C) Resection of intrabronchial tumors or granulation tissue with a laser device. (D) Patients with tracheal stenosis can perform dilatation or placement of endotracheal stents.

(c) Study indications.

The time required for the examination report: slicing and cytological examination, 5-7 days; bacterial and fungal culture results take one week, tuberculosis culture takes 8 weeks to produce results.
