Visible bronchial cannula and application thereof

Abstract

The invention discloses a bronchial cannula for performing a pulmonary ventilation operation on a patient. The bronchial cannula comprises a cannula body and a camera module, wherein the camera moduleis workably installed at the front end of the cannula body to monitor related intraoperative information of the patient.

Description

technical field [0001] The present invention relates to the field of medical devices, and further relates to a visual bronchial intubation used for one-lung ventilation surgery or selective pulmonary ventilation of the left or right bronchi during one-lung ventilation surgery, and further relates to the visual bronchial intubation and its clinical application. Background technique [0002] In medicine, endotracheal intubation refers to the insertion of a special endotracheal tube, such as a visual bronchial tube, endotracheal tube, tracheostomy tube, etc., into the patient's trachea through the oral or nasal cavity. It is a technique for endotracheal anesthesia and patient rescue, and it is also the most reliable means of keeping the upper airway open. In some clinical situations, endotracheal intubation is required to ensure smooth ventilation of the patient's lungs and provide sufficient oxygen. For example: for the implementation of general anesthesia, intracranial surg...

Problems solved by technology

However, when the sputum is more and fills the outlet of the air passage, the gas in the air passage cannot flow out from the outlet of the air passage, and then a negative pressure will be generated in the air passage, causing The sputum cannot flow out from the Murphy hole, thereby blocking the airway, causing inconvenience to the operation, and even causing harm to the patient

In addition, because the interior of the patient's trachea is relatively moist, the fixation performance of the cuff is poor, so the cuff slippage or dislocation often occurs during the operation, which affects the operation process and brings damage to the patient.

[0007] According to foreign statistics, the use of bronchoscope is about 300 U.S. dollars once, but most of the basic hospitals in China cannot afford such a high operation fee, and it is difficult to popularize the traditional use of bronchoscope calibration in China. Depending on bronchial intubation technology, some grassroots hospitals in China cannot carry out lung isolation surgery, that is, they cannot provide patients with timely treatment operations
