Description

Visual bronchial cannula and its application

Technical field

The present invention relates to medical instruments fields, further to for one-lung ventilation operation or one-lung ventilation surgical procedure The visual bronchial cannula of the bronchial selective lung ventilation of middle left or right, further relates to the visual bronchial cannula And its clinical application.

Background technique

Medically, endotracheal intubation refer to by the such as visual bronchial cannula of special trachea cannula, tracheal catheter, Tracheostomy tube etc. is inserted into patient's trachea by oral cavity or nasal cavity.It is a kind of endotracheal anesthesia and the technology to give emergency treatment to a patient, Also the unobstructed most reliable means of the upper respiratory tract are to maintain.There are some cases that need to use endotracheal intubation, in clinic to guarantee Patient lungs' ventilation is smooth, provides enough oxygen.Such as: when to implement entire patient's anesthesia, respiratory tract is difficult to ensure unobstructed Encephalic operation, open chest surgery etc., have using GENERAL ANESTHETICS to breathing and obvious inhibit perhaps using muscle relaxant person or machine need to be carried out Tool ventilation person, when CPR, drug poisoning and newborn's severe asphyxia.

Under normal conditions, endotracheal intubation is divided into single-chamber endotracheal intubation and double lumen tube endotracheal intubation, and the latter is convenient for choosing Use one-lung ventilation to selecting property.For example, visual bronchial cannula, either double lumen tube or single lumen catheter, it is logical to can be used in single lung The bronchial selective lung ventilation of left or right in gas operation or one-lung ventilation surgical procedure.

However, needing for trachea cannula to be inserted and fixed the tracheae of patient, even branch gas in endotracheal intubation Guan Zhong.It for patients with general anesthesia or is given muscle relaxants and loses autonomous respiration patient, need in time, in the shortest time It solves the problems, such as ventilation, the oxygen supply of patient, and to avoid that the organ of patient is caused to damage as far as possible, reduce the generation of complication, Such as respiratory inflammation, mucosal bleeding etc..Meanwhile also needing the tracheae contraposition for guaranteeing trachea cannula and patient accurate, suffered from exempt from customs examination Person brings unpredictable consequence.Especially for Dual-channel tracheal cannula, there are two air passages to respectively correspond as human body for tool The left bronchus of lung and the oxygen supply of right bronchus, it is advantageous that the two sides lung of patient is isolated, help to wither side lung and Expose good visual area.But if the position placement of the Dual-channel tracheal cannula is bad, for example inclination, mistake are aligned or are inserted Enter too deep or excessively shallow etc., and then will cause and can not be isolated or the complication such as poor aeration, hypoxemia.

For example flexible Bronchofiberscope intubation of traditional visual bronchial cannula technology, bougie, optical wand or ignorant of the economics nose visit tracheae Intubation etc. can not all pass through vocal cords, tracheae, and enter in bronchial overall process and provide image guidance.That is, passing In the visual bronchial cannula operation of system, common alignment method has stethoscopy, stethoscopy+suction sputum method or lung compliance detection It needs the doctor for seeking profession by experience Deng, this method, feeling, even through special training judged whether trachea cannula is inserted into later To suitable position, it is accurate then to confirm whether intubation aligns by ancillary equipment such as Bronchofiberscope, if contraposition is bad, needs It is aligned again.Such way, which will necessarily be brought, to find suitable para postion to accurate and confirmation, also just be needed Repeatedly contraposition just can determine that intubation contraposition is correct, meanwhile, difficulty is higher, and higher to the technical requirements of doctor, general doctor is basic Can not operate, even and medical practitioner that contraposition can not also be completely secured is certain accurate.Show still have according to clinical research 37% patient is having found that intubation contraposition is bad after Bronchofiberscope detects, even into non-targeted bronchus.That is, still Have partial surgical can not one-time insertion success rate, needing to carry out repeated detection and aligning just can ensure that intubation contraposition is correct, Jin Erzeng Intubation time is added, and repeatedly intubation can cause patient more to damage.
