Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a single-lung ventilation kit for oncology. Background Technology

[0002] In oncology surgeries, one-lung ventilation is a commonly used anesthetic technique suitable for surgeries requiring unilateral chest cavity exposure, such as those involving lung tumors, esophageal tumors, or mediastinal tumors. Its principle is to selectively block ventilation of the affected lung using a double-lumen endotracheal tube or bronchial obstructor, allowing the healthy lung to independently exchange gases. This provides a clear surgical field and reduces intraoperative lung tissue damage. The technique effectively isolates secretions or blood from the affected side, reducing the risk of cross-infection, while also alleviating surgical pressure on the healthy lung. It is particularly suitable for patients with poor lung function or those whose tumors have invaded the trachea / bronchus. When a bronchial obstructor is inserted into the trachea, it is necessary to use a bronchoscope for observation and guidance. The insertion position of the obstructor is usually a certain distance from the insertion position of the bronchoscope. When passing through difficult airways, when the bronchoscope is processing secretions through the internal suction tube, a certain amount of secretions will obstruct the obstructor, making it difficult for the obstructor to move. This makes it difficult for existing obstructors to pass through the airway quickly and effectively under the guidance of a bronchoscope. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing bronchial obstruction devices rely on bronchoscope path maintenance during placement and lack auxiliary structures for rapid guidance. To address the problems of existing technologies, this invention provides a single-lung ventilation kit for oncology.

[0004] The purpose and effect of this utility model are achieved by the following specific technical means: it includes an external head and an internal head, and a connecting hose is provided between the external head and the internal head; An interface tube is inserted into the external head, and a knob post is perpendicularly connected to the inner side of the interface tube and the connection end of the external head. A transmission rod is provided on the inner end of the knob post and a flow-blocking head is fixed at the end of the transmission rod. A torsion disc that is threadedly engaged with the transmission rod is provided on the outer end of the knob post. The inner tube disc is slidably fitted at the connection end of the built-in head and the connecting hose. The inner tube disc has a movable balloon sleeved on the outer end of the built-in head, and a connecting rib is connected between the inner end of the movable balloon and the inner tube disc. The built-in head has suction holes on its side.

[0005] Furthermore, a clamping ring is embedded on the outer side of the connection end between the external head and the connecting hose, and an open pipe groove for clamping and hooking is left between the inner diameter of the clamping ring and the external head.

[0006] A further preferred embodiment: the flow-blocking head is a conical cylindrical pipe fitting.

[0007] A further preferred embodiment: the connection end between the external head and the connecting hose forms a Venturi tube compartment, and the Venturi tube compartment is disposed opposite to the pipe section between the flow-blocking head and the connecting hose.

[0008] A further preferred embodiment: the movable balloon is a flexible rubber balloon, and the movable balloon has a rubber surface that transitions from thin to thick at the connection end with the connecting rib.

[0009] A further preferred embodiment: the sliding stroke of the inner tube disc is positively correlated with the flexure amplitude of the movable balloon, and the connecting rib is a rubber structure with flexure and elasticity.

[0010] The beneficial effects of this utility model are: This oncology single-lung ventilation kit uses an internally and externally connected tubing structure as the integrated internal tube of the bronchodilator. The tube uses an interface tube at one end to connect to an external suction device, which, together with the suction port at the other end, allows for lateral suction of secretions along the airway path of the bronchodilator. This cleans and maintains the airway by removing residual secretions, ensuring the smooth movement of the bronchodilator. It effectively reduces the difficulty of bronchial bronchodilator placement and the risk of mechanical damage to the airway mucosa. At the same time, it can be used with a bronchoscope for visualized bronchodilator installation, improving the applicability of the kit. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-4The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0015] A single-lung ventilation kit for oncology includes an external head 1 and an internal head 4, with a connecting hose 3 running through the external head 1 and the internal head 4; An interface tube 5 is inserted into the external head 1. A knob post 6 is perpendicularly connected to the inner side of the connection end of the interface tube 5 and the external head 1. A transmission rod 8 is provided on the inner end of the knob post 6 and the end of the transmission rod 8 is fixed with a flow-blocking head 9. A torsion disc 7 that is threadedly engaged with the transmission rod 8 is provided on the outer end of the knob post 6. The inner tube plate 13 is slidably fitted at the connection end of the built-in head 4 and the connecting hose 3. The built-in head 4 is fitted with a movable balloon 12 at the outer end of the inner tube plate 13, and a connecting rib 14 is connected between the inner end of the movable balloon 12 and the inner tube plate 13. The built-in head 4 has suction holes 11 on its side; This kit serves as an auxiliary built-in structure for a bronchial obstructor. The structural tubing and the obstructor tube are nested in a two-section design. The connecting hose 3 is separated from the obstructor tubing and is independently sealed. The built-in head 4 at the end of the connecting hose 3 mainly uses the suction hole 11 as a clamping slot for the external tube of the obstructor. This allows the built-in head 4 to be positioned on the head side of the obstructor tubing insertion end and to be secured to the obstructor tubing using the movable balloon 12 structure. The other end uses the interface tube 5 of the external head 1 to connect to the suction airway. When the obstructor is inserted, as the tubing is advanced, the suction airway can act along the side of the obstructor via the connecting hose 3 to suction and clean the secretions along the obstructor's path. This avoids mechanical damage to the airway mucosa caused by changes in the insertion angle of the tubing end due to obstruction of secretions when the obstructor is directly inserted, thereby improving the safety and practicality of the kit. Specifically, the airway of the connecting hose 3 is mainly controlled by the screwing structure on the external head 1. During installation, the operator can hold the external head 1 and screw the twisting disc 7 to drive the transmission rod 8 to move axially in and out through the rotation of the twisting disc 7. That is, the size of the cavity between the external head 1 and the connecting hose 3 is changed by the flow-blocking head 9 at the other end of the transmission rod 8 to adjust and control the negative pressure of the airflow in the suction tube. Combined with the connecting hose 3 and the internal head 1, secretions in the path of the blocker are suctioned. At the same time, after the blocker is installed, the position of the inner tube disc 13 can be changed by pulling the connecting hose 3 outward. The inner tube disc 13 slides along the diameter of the internal head 4 to stretch the connecting rib 14 and the movable balloon 12, thereby reducing the size of the varicose expansion of the movable balloon 12, so that the internal head 4 can be quickly separated from the outer tube of the blocker so that the blocker can be left in the bronchial airway. Specifically, a clamping ring 2 is embedded on the outside of the connection end between the external head 1 and the connecting hose 3. An open pipe groove for clamping and hanging is left between the inner diameter of the clamping ring 2 and the external head 1. The external head 1 serves as the hanging and fixing structure of the outer end of the blocker pipeline through the clamping ring 2 and the pipe groove. Furthermore, the flow-restricting head 9 is a tapered cylindrical pipe fitting, such as... Figure 2 As shown, the flow-blocking head 9, as a conical column structure, can gradually narrow the internal air passage by utilizing the conical surface of the flow-blocking head 9 during the process of the transmission rod 8 being screwed into the internal pipeline of the external head 1, thereby further improving the air pressure regulation accuracy of the torsion disc 7. Furthermore, a Venturi tube 10 is formed at the connection end between the external head 1 and the connecting hose 3, and the Venturi tube 10 is positioned relative to the pipe section between the flow-blocking head 9 and the connecting hose 3, such as... Figure 2 As shown, by using the Venturi tube chamber 10 as the passage cavity between the connecting hose 3 and the external head 1, the airflow efficiency of the negative pressure airway from small to large diameter pipe can be effectively reduced when the negative pressure airway is discharged along the connecting hose 3 to the outer end of the external head 1, thus ensuring the balance of the negative pressure airway in the connection section between the connecting hose 3 and the external head 1. Furthermore, the movable balloon 12 is a flexible rubber balloon, and the movable balloon 12 has a rubber surface that transitions from thin to thick at the connection end with the connecting rib 14, such as... Figure 3 , 4 As shown, the movable balloon 12 uses a transition surface as the snap-fit ​​surface structure with the outer encapsulation tube of the occluder, and a relatively thick rubber surface as a limiting structure in the outer direction of the connecting hose 3, so as to ensure the snap-fit ​​stability between the inner head 4 and the occluder tube, and to ensure the axial fixing strength of the connecting hose 3 when the movable balloon 12 expands.

[0016] Furthermore, the sliding stroke of the inner tube disc 13 is positively correlated with the expansion and contraction amplitude of the movable balloon 12, and the connecting rib 14 is a rubber structure with elasticity. When the connecting hose 3 is stretched outward to allow the inner tube disc 13 to slide and the movable balloon 12 to be stretched using the connecting rib 14, it is necessary to further overcome the elasticity of the connecting rib 14 to provide a relative buffer distance for the expansion structure of the movable balloon 12, avoid the direct impact of the small-amplitude stretching of the connecting hose 3 on the expansion degree of the movable balloon 12, and further improve the reliability of the fixed structure of the movable balloon 12.

[0017] This kit serves as an auxiliary built-in structure for the bronchial occluder. The connecting tubing 3 is nested outside the occluder tubing and individually encapsulated. It is secured to the encapsulated tubing wall by the expansion of the movable balloon 12. The suction port 11 of the built-in head 4 is located on the rear side of the occluder balloon position. When installing the obstruction device, the interface tube 5 of the external head 1 is used to connect to the external negative pressure suction device. During the insertion of the obstruction device, with the observation of the bronchoscope, the secretions in the path of the obstruction device can be suctioned and cleaned along the connecting hose 3 by turning the negative pressure suction device on and off. During the procedure, the operator can hold the external head 1 and rotate the twisting disc 7 to drive the transmission rod 8 to extend and retract axially. That is, the flow-blocking head 9 at the other end of the transmission rod 8 changes the size of the cavity between the external head 1 and the connecting hose 3, so as to regulate and control the negative pressure of the airflow in the suction tube. Combined with the connecting hose 3 and the internal head 1, the secretions in the path of the blocker are suctioned. After the occluder is installed, the position of the inner tube disc 13 can be changed by pulling the connecting hose 3 outward. The inner tube disc 13 slides along the diameter of the inner head 4 to stretch the connecting rib 14 and the movable balloon 12, thereby reducing the size of the varicose expansion of the movable balloon 12. This releases the fixation between the inner head 4 and the outer encapsulation tube wall of the occluder, making it easier to quickly separate the inner head 4 from the outer encapsulation tube of the occluder so that the occluder can remain in the bronchial airway.
