Technical Field
[0001] The utility model belongs to the field of medical devices, and specifically relates to a novel visual double-blocking double-lumen endobronchial cannula. Background Art
[0002] A double-lumen endobronchial tube is a medical device used to provide bilateral airway isolation during anesthesia and respiratory support. This tube is usually used in surgeries that require single-lung ventilation or separate ventilation of both lungs, such as thoracic surgery.
[0003] However, the current double-lumen endobronchial tube can only block one side of the bronchus. If one side of the patient's bronchus is difficult to align or bilateral lung surgery requires bilateral blockage, the double-lumen endobronchial tube often needs to be replaced, which increases the risk of airway damage to the patient and increases the patient's medical costs. In view of this, the present invention is specially proposed. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel visual double-blocking double-lumen endobronchial tube.
[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:
[0006] A novel visual double-blocking double-lumen endobronchial cannula comprises a main cannula, an auxiliary blocking tube, and a connector. The auxiliary blocking tube is fixed to the upper end of the main cannula, and a connector is fixed to one side of the main cannula and the auxiliary blocking tube. A clearance hole is opened on the lower middle side of the connector, which communicates with the first and second operating lumens inside the main cannula. A through hole is opened on the upper middle side of the connector, which communicates with the third operating lumen inside the auxiliary blocking tube.
[0007] A reserved cavity for installing the camera module is provided through the middle of the upper inner wall of the main cannula, and the tail end of the camera module is passed through the external wire to the outside of the connector;
[0008] Gas injection cavities are provided inside the two side walls of the first operating cavity and the upper side wall of the auxiliary blocking tube, and the ends of each gas injection cavity are respectively connected to the main tracheal blocking cuff, the bronchial blocking cuff and the auxiliary tracheal blocking cuff;
[0009] One side of the plurality of gas injection channels passes through the first conduit to the outside of the joint and is communicated with the first gas injection head.
[0010] Optionally, the auxiliary sealing tube and the side wall of the second operating chamber are provided with memory bending ends, and an air inlet cavity connected to the auxiliary sealing tube and the side wall of the second operating chamber is provided inside the two memory bending ends. The outer end of each air inlet cavity is connected to a second conduit, and the outer end of each second conduit is connected to a second gas injection head.
[0011] Optionally, the lower end of the main cannula is provided with scale marking layers at equal intervals, and the material of the scale marking layers is a developing material.
[0012] Optionally, the inner walls of one end of the first operating cavity, the second operating cavity and the third operating cavity are all integrally formed with multiple first anti-slip rings, and the first operating cavity, the second operating cavity and the third operating cavity are all in contact with the first silicone sealing head through the first anti-slip rings.
[0013] Optionally, the inner walls of the ends of the second operating cavity and the third operating cavity are integrally formed with a plurality of second anti-slip rings, and the second operating cavity and the third operating cavity are in contact with the second silicone sealing head through the second anti-slip rings.
[0014] Optionally, the outer walls of the first silicone plugging head and the second silicone plugging head are evenly spaced with grooves that are compatible with the outer dimensions of the first anti-slip ring or the second anti-slip ring, and the outer ends of the first silicone plugging head and the second silicone plugging head are both fixed with pull-out heads.
[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:
[0016] 1. The present invention has the function of blocking the contralateral bronchus. When double-lung surgery is required, or one lung is poorly aligned and the contralateral bronchus needs to be blocked, there is no need to change the tube. The main tracheal blocking cuff, bronchial blocking cuff, and auxiliary tracheal blocking cuff are inflated and then expanded to block the trachea undergoing surgery. Compared with the existing double-lumen endobronchial intubation, the number of intubations is reduced, the occurrence of intubation-related complications is reduced, and on the other hand, resource waste is reduced, and patient costs are reduced. In addition, the present invention has a visual function, and the alignment of the bronchial intubation and the blocking tube can be performed under direct vision, without the need for fiber bronchoscope-assisted alignment. This facilitates the operator to perform intubation and reduces the difficulty and complications of intubation.
[0017] 2. The present invention takes into account the external contours and Y-shape of the main trachea and bronchus. Therefore, in order to facilitate medical staff to quickly complete the alignment and blocking during surgery, the present device will adjust the use direction of the bronchial blocking cuff and the auxiliary tracheal blocking cuff by connecting the memory bending end, the air inlet cavity, the second catheter and the second air injection head to the air injection medical equipment. That is, the air inlet cavity is filled with gas during the process of inserting the device, and the memory bending end is in a vertical state under the filling of gas. After insertion, when the bronchus needs to be blocked, the gas is extracted. At this time, the air inlet cavity lacks gas filling, and the memory bending end is reset. At this time, the bronchial blocking cuff and the auxiliary tracheal blocking cuff will face the stent tube. Then the bronchial blocking cuff and the auxiliary tracheal blocking cuff are internally injected with air or physiological saline to expand and complete the blocking process.
[0018] The specific implementation of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The present invention will now be described in further detail with reference to the accompanying drawings.
[0029] See also Figures 1 to 4The utility model provides a technical solution: a new type of visual double-blocking double-lumen endobronchial cannula, comprising a main cannula 1, an auxiliary blocking tube 2 and a connector 3. The upper end of the main cannula 1 is fixed with the auxiliary blocking tube 2, and the connector 3 is fixed on one side of the main cannula 1 and the auxiliary blocking tube 2. A clearance hole communicating with the first operating cavity 4 and the second operating cavity 5 inside the main cannula 1 is opened on the lower middle side of the connector 3, and a through hole communicating with the third operating cavity 6 inside the auxiliary blocking tube 2 is opened on the upper middle side of the connector 3.
[0030] A reserved cavity for installing the camera module 7 is opened through the middle of the upper inner wall of the main cannula 1, and the tail end of the camera module is connected to the outside of the connector 3 through an external wire 8;
[0031] Gas injection channels 9 are provided on both side walls of the first operating chamber 4 and the upper side wall of the auxiliary blocking tube 2. The ends of each gas injection channel 9 are respectively connected to the main tracheal blocking cuff 10, the bronchial blocking cuff 11 and the auxiliary tracheal blocking cuff 12;
[0032] One side of the multiple gas injection channels 9 passes through the first catheter 24 to the outside of the connector 3 and is connected to the first gas injection head 13. Considering that the current double-lumen endobronchial tube can only block one side of the bronchus, if one side of the patient's bronchus is difficult to align, bilateral lung surgery, etc. require bilateral blockage, it is often necessary to replace the double-lumen endobronchial tube, which will increase the risk of airway damage to the patient and increase the patient's medical costs. When the present invention is used, gas or saline can be injected into the gas injection channel 9 through the first catheter 24 according to surgical needs, and then enter the corresponding main tracheal blocking cuff 10, bronchial blocking cuff 11 and auxiliary tracheal blocking cuff 12, and expand them to complete the tracheal blockage, thereby avoiding tissue fluid or tissue entering the trachea during surgery to cause a critical situation.
[0033] Among them, the side walls of the auxiliary blocking tube 2 and the second operating cavity 5 are both provided with memory bending ends 14, and the interior of the two memory bending ends 14 is provided with an air inlet cavity 15 connected with the interior of the side walls of the auxiliary blocking tube 2 and the second operating cavity 5. The outer end of each air inlet cavity 15 is connected with a second catheter 16, and the outer end of each second catheter 16 is connected with the second gas injection head 17. Taking into account the external contours and Y-shape of the main trachea and bronchus, in order to facilitate medical staff to quickly complete the alignment and blocking during surgery, this device will be connected to the gas injection medical device through the memory bending end 14, the air inlet cavity 15, the second catheter 16 and the second gas injection head 17. After the connection is completed, air is injected to adjust the use direction of the bronchial blocking cuff 11 and the auxiliary tracheal blocking cuff 12, that is, the process of inserting the device is summarized as the air inlet cavity 15 is filled with gas, and the memory bending end 14 is in a vertical state when filled with gas. After insertion, when it is necessary to block the bronchus, the gas is extracted. At this time, the inside of the air inlet cavity 15 lacks gas filling, and the memory bending end 14 is reset. At this time, the bronchial blocking cuff 11 and the auxiliary tracheal blocking cuff 12 will face the stent tube, and then the inside of the bronchial blocking cuff 11 and the auxiliary tracheal blocking cuff 12 is injected with air or physiological saline to expand and complete the blocking process.
[0034] Among them, the lower end of the main cannula 1 is provided with a scale layer 18 at equal intervals, and the material of the scale layer 18 is a developing material. By setting the scale surface layer, it is convenient for medical staff to know the insertion depth of the device through the developing equipment, thereby improving the accuracy of the device insertion.
[0035] Among them, the inner walls of one end of the first operating cavity 4, the second operating cavity 5 and the third operating cavity 6 are all integrally formed with multiple first anti-slip rings 19, and the first operating cavity 4, the second operating cavity 5 and the third operating cavity 6 are all in contact with the first silicone sealing head 20 through the first anti-slip ring 19. By setting the first silicone sealing head 20, the end of the second operating cavity 5 or the third operating cavity 6 that is not used during the operation is sealed, and the other end will be sealed by the second silicone sealing head 22 in cooperation with the second anti-slip ring 21.
[0036] Among them, the inner walls of the ends of the second operating chamber 5 and the third operating chamber 6 are integrally formed with multiple second anti-slip rings 21, and the second operating chamber 5 and the third operating chamber 6 are both in contact with the second silicone sealing head 22 through the second anti-slip rings 21. By setting the second anti-slip rings 21, the friction between the second silicone sealing head 22 and the second operating chamber 5 and the third working chamber is increased. The second silicone sealing head 22 needs to be removed when the device is used, and the first silicone sealing head 20 can be removed according to actual needs.
[0037] Among them, the outer walls of the first silicone sealing head 20 and the second silicone sealing head 22 are evenly spaced with grooves that are adapted to the external dimensions of the first anti-slip ring 19 or the second anti-slip ring 21, and the outer ends of the first silicone sealing head 20 and the second silicone sealing head 22 are both fixed with a pull-out head 23. The provision of the grooves facilitates the close fit between the first anti-slip ring 19 or the second anti-slip ring 21 and the first silicone sealing head 20 and the second silicone sealing head 22.
[0038] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
