Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable, bendable, and balloon-position-monitoring occluder. Background Technology

[0002] Intrathoracic surgery often requires single-lung ventilation, which involves isolating the affected bronchus, causing that lung to collapse, and using the other lung for mechanical ventilation to maintain intraoperative oxygenation. This technique of isolating one lung is also known as lung isolation. Lung isolation typically uses a double-lumen endotracheal tube, using tracheal and bronchial cuffs to isolate the left and right bronchi separately. The main disadvantage of a double-lumen endotracheal tube is its thickness and rigidity, leading to frequent postoperative complications such as sore throat, glottis, and airway damage.

[0003] Lung isolation can also be achieved using a single-lumen endotracheal tube combined with a bronchial occluder. This involves inserting the bronchial occluder into the bronchus through the endotracheal tube, and then sealing the bronchus on the affected side using a bronchial cuff. Currently, there are two types of bronchial occluders: rigid bronchial occluders, which can be adjusted left and right after endotracheal tube insertion to control their entry into a specific bronchus; and flexible bronchial occluders, which require guidance by placing the tip of the occluder over a fiberoptic bronchoscope. Regardless of the type of bronchial occluder, a fiberoptic bronchoscope is required to confirm or guide its position. However, the sterilization process for fiberoptic bronchoscopes is complex and often inefficient for clinical use. Inadequate sterilization can also lead to cross-infection. There is an occluder on the market with a camera module attached to the back of the balloon. However, these devices are made entirely of rigid materials and have a pre-shaped tip with specific angles for the left and right bronchi. As a result, these devices cannot be shared when temporarily replacing collapsed lungs during surgery, leading to a heavy workload for medical staff and higher medical costs for patients. Furthermore, the camera module at the tip takes up space and prevents the suction of secretions during surgery.

[0004] Therefore, traditional occluders are difficult to combine the functions of being visible, flexible, capable of monitoring balloon position, and capable of aspirating secretions. In response to the above-mentioned deficiencies, this application is proposed. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides an adjustable-bend occluder with monitorable balloon position, comprising an adjustment control component, a secretion suction connector, an occluder tube, an occluder balloon, and a camera module. The occluder tube has an adjustment section, the adjustment control component includes a traction rope for controlling the bending of the adjustment section, the occluder tube has a secretion suction channel, the occluder balloon is installed in the adjustment section and connected to the balloon inflation cavity in the occluder tube, the camera module is installed on the occluder tube and positioned behind the occluder balloon, and the occluder tube has a secretion suction hole located in front of the occluder balloon. The secretion suction channel is connected to the secretion suction connector and the secretion suction hole.

[0007] The bending control component controls the bending of the bending section, allowing for real-time adjustment based on the structure of the trachea and bronchi during intubation. The camera module provides a field of view for medical staff during occlusion, enabling them to perform intubation in a controlled environment, reducing the difficulty and improving accuracy. Depending on clinical needs, secretions during the procedure can be aspirated via a secretion aspiration connector, thus giving the occluder the functions of visualization, flexibility, monitoring balloon position, and secretion aspiration.

[0009] The sealing mating part and the sealing cover can be configured as an interference fit or a threaded fit, with a threaded fit being preferred. The sealing mating part and the sealing cover are respectively provided with external threads and internal threads.

[0010] The main interface is used to connect to a ventilator or endotracheal tube.

[0011] According to one embodiment of the present invention, the camera module is connected to a module signal connector, which is used to transmit image information of the camera module and can be connected to a display.

[0012] According to one embodiment of the present invention, the adjustable and monitorable balloon position occluder also includes a handle. The adjustment control component, the secretion suction connector and the module signal connector are all mounted on the handle for easy use and operation.

[0030] like Figure 3 The handle 1 includes a housing and a bending control assembly 11, a secretion suction connector 13, a module signal connector 12, and a balloon endotracheal connector 14 mounted on the housing. The secretion suction connector 13 is preferably a Luer connector. The module signal connector 12 is used to connect to the camera module 5. The balloon endotracheal connector 14 is connected to the balloon inflation channel in the occluder tube 3 for inflating the occlusion balloon 4.

[0031] The bending control assembly 11 includes a rotatable hub 112, a rope fixing assembly 113 disposed on the hub 112, a bending wrench 111 connected to the hub 112, and a traction rope 115. The hub 112 is rotatably mounted in the housing of the handle 1. The bending wrench 111 is disposed on the outer circumference of the hub 112. Two sets of rope fixing assemblies 113 are provided and a screw fixing structure is adopted. The traction rope 115 is preferably a steel wire rope, and the end of the traction rope 115 is fixed by screws.

[0032] The secretion suction connector 13, module signal connector 12 and balloon endotracheal connector 14 are located on the upper side of the handle and are tilted upwards. The bending wrench 111 is located on the lower side of the handle. This arrangement facilitates the bending operation.

[0033] A limiting groove 114 is installed on the housing, and a screw located in the limiting groove is provided on the hub 112. The hub 112 can rotate within the limited angle range of the limiting groove 114, preferably 0~80°.

[0034] 3 such as the plug tube body Figure 2 The occluder tube body 3 is provided with a bending section, and the bending control component 11 is used to control the bending of the bending section. The front end of the occluder tube body 3 is provided with a tip 33, and the secretion suction hole is provided on the tip 33. At least two sets of traction ropes 115 are provided, and the traction ropes 115 are connected to the tip 33. The occluder tube body 3 is provided with a secretion suction channel 32 and a balloon inflation chamber. The secretion suction channel 32 is connected to the secretion suction connector 13 and the secretion suction hole. The occlusion balloon 4 is installed in the bending section, and the balloon inflation chamber is connected to the occlusion balloon 4 and the balloon tracheal connector 14. The camera module 5 is installed on the occluder tube body 3 and is located on the rear side of the occlusion balloon 4. The camera module 5 is connected to the module signal connector 12, which is used to transmit the image information of the camera module 5 and can be connected to a display.

[0035] The bending section is provided with a snake bone structure or a flexible metal part 31, which can be a spring structure or a metal woven mesh.

[0036] The bending section is preferably bent within a 120° vertical range; the occluder tube 3 is a three-lumen tube, with the secretion suction channel 32 also functioning as an embedded spring or snake-like structure, and serving as a suction cavity; the balloon inflation cavity is for inflating and deflating the balloon; another cavity is used for threading the camera signal cable. The tip is preferably tapered to reduce resistance when lowering the tube. Figure 3 As shown.

[0037] A camera with at least 100,000 pixels is placed approximately 10mm from the rear end of the occlusion balloon. This provides medical staff with a field of vision during insertion, allowing them to perform the insertion within the ward, reducing the difficulty and improving accuracy. After successful insertion, the balloon's status and position can be monitored in real time. In case of displacement or leakage, imaging support is provided, reducing the probability of medical accidents.

[0038] During intubation, the device is adjusted in real time using a bending wrench 111 according to the structure of the human trachea and bronchi. When medical staff want to switch to occlusion on one side of the bronchus, the air in the occlusion balloon can be evacuated, the tube placed on the other side, and the balloon inflated again to complete the occlusion. This improves work efficiency and saves resources. Existing occluders are all pre-molded at the front end, but the structure of the left and right bronchi in the human body is different. The same occluder cannot complete the occlusion of both sides at the same time. Using the same occluder will cause air leakage, damage to the human body, and medical accidents.

[0039] The device can be adjusted in real time according to the structure of the human trachea and bronchi during intubation. The camera module 5 is used to provide medical staff with a field of vision when the occluder is inserted, so that medical staff can perform intubation in the department, reducing the difficulty of intubation and improving the accuracy. According to clinical needs, secretions during the operation can be aspirated through the secretion aspiration connector 13, so that the occluder has the functions of being visible, flexible, able to monitor the position of the balloon, and able to aspirate secretions.

[0040] like Figure 4 The adjustable and monitorable balloon position occluder also includes a conversion connector 2 installed on the occluder tube body 3, the conversion connector 2 being provided with a main interface 21 and a tube body sealing structure.

[0041] The main interface 21 is used to connect to a ventilator or endotracheal tube.

[0042] The tube body sealing structure includes a silicone body 24, a sealing mating part 23 located outside the silicone body 24, and a sealing cap 22 for connecting with the sealing mating part 23. The sealing mating part 23 and the sealing cap 22 are tapered. The sealing mating part 23 is used to squeeze the silicone body 24 to seal the tube body 3 of the plugger.

[0043] The sealing mating part 23 and the sealing cover 22 can be configured as an interference fit or a threaded fit. The sealing mating part 23 is a conical cylindrical structure, which is a deformable structure. For example, it can be provided with an axially set expansion joint of a certain length or be made of a deformable material. The silicone body 24 is cylindrical and located inside the sealing mating part 23. Preferably, a threaded fit is used. The sealing mating part 23 and the sealing cover 22 are respectively provided with external threads and internal threads. The sealing cover 22 has a conical inner hole. When the sealing cover 22 is tightened on the sealing mating part 23, the sealing mating part 23 compresses the silicone body 24 under the action of the cone to achieve a sealing effect and ensure that oxygen does not leak during use.

[0044] During use, the module camera connector is connected to the display assembly. At this time, the balloon is in a deflated state. Medical staff place this product into a regular endotracheal tube. Under visual guidance, it reaches the trachea and the front end of the bronchus. According to the needs of medical staff and human anatomy, the bending wrench 111 is operated to pull the steel wire rope, bending the front end to allow for deeper insertion into the bronchus. Under visual guidance, it reaches the predetermined position and the occlusion balloon is inflated. One end of the adapter is connected to the endotracheal tube or ventilator, and the tube body is sealed. The occlusion and placement are complete. During the operation, the camera module continuously monitors the balloon status and can also suction secretions during the operation as needed.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
