Description

Technical Field

[0001] The invention relates to the technical field of tracheal surgery, in particular to a fiberbronchoscope auxiliary device for patients undergoing tracheotomy. Background Art

[0002] Tracheotomy is a surgical procedure in which an opening is made in the front wall of the trachea in the neck, a tracheal cannula is inserted, and a new breathing passage is established. The main purpose is to relieve upper airway obstruction, ensure airway patency, facilitate the removal of tracheal secretions, or provide long-term mechanical ventilation support. For patients with airway obstruction caused by laryngeal edema, laryngeal tumors, etc., tracheotomy is an important life-saving measure. Incision care should keep the tracheotomy incision clean and dry. The tracheal cannula should be firmly fixed to prevent displacement or dislocation. Generally, an inch-bandage is used to fix the tracheal cannula. The tightness should be able to accommodate one finger. Too loose may cause the cannula to dislocate, while too tight may cause patient discomfort and even affect blood circulation in the neck.

[0003] Fiberoptic bronchoscope, also known as fiberoptic bronchoscope, is a medical device used to examine tracheal, bronchial and lung lesions. It is mainly composed of fiberoptic optical system, lighting system, working channel and operating unit. The fiberoptic optical system can transmit images from the inside of the bronchus to the external eyepiece or display screen, so that doctors can clearly observe the situation inside the bronchus. The lighting system provides enough light to illuminate the inspection site. The working channel can be used to attract secretions, inject drugs or insert biopsy instruments. Patients need local anesthesia, generally through atomization inhalation or nasal or throat spray using lidocaine and other local anesthetics. This can reduce the patient's discomfort during the examination and reduce the cough reflex. The doctor will learn about the patient's medical history, allergy history and other related information in detail, and assess the patient's basic physical condition such as cardiopulmonary function to ensure that the patient can tolerate the examination.

[0004] Existing tracheotomy patients may experience sputum spurting out of the tracheotomy when using a bronchoscope. This is mainly due to the gap between the tracheotomy opening and the bronchoscope, which causes the bronchoscope to squeeze the sputum during movement, causing it to overflow, polluting the surgical environment and reducing work efficiency.
