Description

Visual multi-functional bronchus plugging device of intelligence

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an intelligent visual multifunctional bronchus blocking device.

Background

The thoracic surgery needs an anesthesiologist to implement a lung isolation technology, namely, a technology of separating ventilation paths of a left lung and a right lung at the level of a trachea bulge or a bronchus and ventilating one lung, mainly has the effect of enabling the operated side lung to be unventilated and gradually collapsed, so that a space for surgical operation is generated in a thoracic cavity, the technology is particularly suitable for the thoracoscope operation, is a key core technology of thoracic anesthesia, and is implemented in a national amount of not less than 30 ten thousand cases/year. The current lung isolation technology mainly comprises two types of double-cavity tubes and a bronchus stopper, wherein the application of the double-cavity tubes accounts for 70 percent, the application range is wide, the method is a traditional classic method, and a visual product is provided at present, but due to the double-cavity tube design, the diameter is thick, the occurrence rate of airway injury is relatively high, the air passage injury can not be used for difficult air passages sometimes, and the double-cavity tubes can be exchanged for patients with the existing trachea cannula through special auxiliary tools; the bronchus stopper is thin in pipe diameter, one side of the bronchus can be blocked by the saccule to cause that one side of the lung is not ventilated, the same lung isolation effect as the double-cavity pipe is realized, the flexibility is high, the application accounts for 30 percent at present, but the double-cavity pipe is gradually increased and replaced in the field of thoracoscope minimally invasive surgery. With the development of thoracic surgery technology, minimally invasive surgery is gradually becoming the mainstream and the front direction, and the advantage of minimally invasive bronchial occluders is more prominent; in addition, in recent years, development of partial difficult operations brings new requirements on lung isolation technology, such as chest operation of patients with difficult air passages, and the first choice is the bronchus blocking device; in partial complicated tracheal surgery, the problem of insufficient oxygenation due to special high-frequency ventilation through a catheter is also considered while lung isolation is considered; the anesthesia of part of the fast channel thoracoscopic surgery adopts the laryngeal mask technology to assist ventilation, the lung isolation is realized by the aid of the bronchial occluder (occasionally, the high-frequency ventilation is connected), the clinical changes have higher requirements and challenges for the existing lung isolation technology and device, and the development of a novel bronchial occluder is helpful to adapt to the changes.

One type of the existing common bronchus occluder can complete the catheterization only under the visual guidance of a fiberoptic bronchoscope. During the operation, if the bronchus stopper is displaced, the position also needs to be adjusted under the assistance of the fiberbronchoscope. This requires the operator to be skilled in the bronchofiberscope technology and to disinfect and maintain the bronchofiberscope, which adds virtually to the cost of use. In addition, assistant is needed in the operation process, the bronchial occluder cannot realize whole-process visualization, and the application of the device is limited due to the defects that the bronchofiberscope is used for observation and positioning, and the like.

The second type is a visual bronchial occluder. Chinese utility model patent (grant publication No. CN 206166970U) discloses a visual bronchus stopper, including hollow single cavity pipe, the one end periphery side that the single cavity pipe stretched into the bronchus is equipped with the gasbag, and the outer tip that the single cavity pipe passed the gasbag and outwards extended is equipped with visual device, is equipped with the cleaning device that can get rid of the fender thing of looking in one side of visual device. The visual bronchus stopper is combined with a visual single-cavity tube to realize visualization, but the visual single-cavity tube has thicker and harder tube diameter than the common single-cavity tube due to the additional arrangement of a visual camera, and simultaneously has limitation in clinical application of occupying more airway space and other problems, and the visual single-cavity tube cannot be used independently without the camera.

The utility model patent of China (application publication No. CN 109009309A) discloses a visual bronchus stopper, which comprises a bronchus stopper catheter, a micro camera, a video transmission line, an image switching jack, a display, an inflation indicating air bag, an inflation connecting pipe, a stopper air bag, a breathing machine connecting part, a vent hole and a plastic guide steel wire. The occlusion device integrates the micro camera at the far end of the cuff of the head of the bronchial occlusion catheter, and the far end of the cuff is also provided with a section of ventilation function lumen, but because the far end of the occlusion cuff is provided with the length of a section of catheter, the visual occlusion tube can not be applied to the occlusion of the lung lobe resection, which causes troubles to surgical operation, and in addition, the relative position relationship between the balloon and the trachea bulge can not be seen, and whether the depth of the bronchial occlusion device is proper or not can not be judged, so that the clinical application of part of the bronchial occlusion device is also limited.

The utility model discloses a china utility model patent (No. CN 209595824U) discloses an adjustable bronchus plugging device, including outer pipe, the one end of outer pipe is provided with air inlet joint, and the middle part of outer pipe is provided with Y shape and connects, and air inlet joint's one end is kept away from to outer pipe is connected with multi-functional crossover sub, and the one end that outer pipe was kept away from to multi-functional crossover sub is connected with the sleeve pipe, and sheathed tube inside is provided with the pipe of ventilating, and the one end that multi-functional crossover sub was kept away from to the sleeve pipe is provided with miniature camera head, and the one end that multi-functional crossover sub was kept away from to the sleeve pipe is provided with the hose, and the sheathed tube one end is kept away from to the hose is connected with the shutoff gasbag. The catheter is designed by an inner sleeve and an outer sleeve and has the following defects: (1) the effective ventilation cavity is small, so that the ventilation resistance is increased, (2) the camera is positioned on the outer sleeve, and once the camera is polluted by secretions, the suction catheter is difficult to insert to clean the air passage and the camera, so that the use effect is affected; (3) the visual angle of the camera is small, the balloon of the occluder cannot be shot completely, and the device has single function and cannot meet various requirements in the operation.

In addition, for patients with higher risk of cross infection, if the operation needs to be performed, the disposable video catheter is suitable, for example, when a respiratory system operation is performed on a new coronary pneumonia patient, if the bronchofiberscope is used for assisting positioning every time, the risk of cross infection is obviously increased, and the operation is not suitable; furthermore, it is possible that some patients may have advanced tracheal intubation due to respiratory failure and then have to be replaced by a tube exchanger to double lumen also increasing the risk of cross-infection. For a patient with high risk of pathogenic virus infection like new coronary pneumonia, if lung isolation is required to be implemented and a patient with cross infection is required to be avoided, a lung isolation device with convenient, multifunctional and simple operation process is required. Guidelines for intubation of new coronary patients with pneumonia recommend rapid sequential intubation, avoid positive pressure ventilation, and reduce exhalation of aerosols from new coronary patients during intubation. Therefore, the ideal choice for such patients to perform lung isolation is to insert the single lumen tube or laryngeal mask first and then place the visible bronchial stopper, and preferably simultaneously achieve a series of ancillary functions such as temperature monitoring, adequate suction drainage and high frequency ventilation by one device.
