Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a multifunctional visual bronchoscope. Background Art

[0002] Rigid bronchoscopes are essential tools for respiratory interventional procedures. Most basic respiratory interventional procedures can be performed with a rigid bronchoscope. The use of this device significantly improves the convenience and safety of respiratory interventional procedures.

[0003] In recent years, with the rapid development of respiratory endoscopic interventional technology, the unique advantages of rigid bronchoscopes have made their application areas increasingly extensive, and they have become an indispensable and important role in the field of respiratory intervention. Central airway stenosis, stent placement, various endoscopic hot and cold ablation treatments and other scenarios can all be achieved with the help of rigid scopes for respiratory endoscopic interventional treatment. There are two ways to insert a traditional rigid scope: using a rigid scope with a bronchoscope, which requires one hand to hold the bronchoscope in place during operation. It is not easy to fix and the head is easily affected by secretions that affect the field of vision, so the scope needs to be removed and the lens wiped before reinsertion; fiber bronchoscope-assisted insertion requires an experienced assistant to hold the fiber bronchoscope device to guide the scope in. To achieve successful rigid scope placement, high requirements are placed on the assistant equipment, rigid scope equipment, and the degree of tacit understanding between the operator. This makes rigid scope placement a high-threshold operation for respiratory endoscopic intervention, which discourages many beginners. In addition, when traditional rigid endoscopes are inserted, the endoscope is in an open state during the operation, which causes patients to often experience problems such as insufficient tidal volume of the ventilator, frequent air leaks, and even hypoxemia during the operation, further increasing the risks of rigid endoscope operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a multifunctional visual bronchoscope.

[0005] To achieve the above purpose, the technical solutions adopted by the present invention are as follows:

[0006] A multifunctional visual bronchoscope, comprising a bronchoscope and a multifunctional visual device, wherein a jet ventilation interface and a ventilator interface are provided on one side of the upper portion of the bronchoscope, a flexible end is provided at the lower end of the bronchoscope, and a plurality of ventilation side holes evenly distributed along the axial direction are opened on the lower side wall of the bronchoscope;

[0007] The multifunctional visual device includes an insertion tube located inside the bronchoscope, the insertion tube includes a suction tube and a data line tube, the upper end of the suction tube is connected to the suction connector through a connector seat, the suction connector is provided with an internal suction port, the suction connector is provided with a suction outlet, the outer side of the suction connector is provided with a suction connector button, the lower end of the data line tube is provided with a visual camera, the visual camera is connected to the data extension line extending from the top of the data line tube, and the data extension line is connected to the data interface.

[0008] Furthermore, a flexible joint is fixed on the joint seat by a buckle, a flexible mirror entrance is opened in the center of the flexible joint, and a joint cover is connected to the side wall of the flexible joint.

[0009] Furthermore, a suction inlet is provided at the lower end of the suction tube.

[0010] Furthermore, the jet ventilation interface is connected to a jet ventilator pipeline.

[0011] Furthermore, the ventilator interface is connected to the ventilator pipeline.

[0012] Furthermore, the lower outer wall surface of the joint seat is a joint seat outer ring, and the joint seat outer ring is a conical surface.

[0013] Compared with the prior art, the outstanding effects of the present invention are:

[0014] (1) The outer ring of the connector seat of the multifunctional visual bronchoscope of the present invention adopts a tapered design, which can be quickly assembled with the bronchoscope and is easy to install.

[0015] (2) The insertion tube is a double-tube or double-lumen structure, including a suction tube and a data line tube. It can be inserted into the patient's tracheal or bronchial lesion under visualization, and at the same time, sputum, blood or secretions in the trachea or bronchus can be attracted under visualization. No assistant is required, and a single person can quickly insert the rigid endoscope, which simplifies the operation process, reduces the difficulty of operation, and allows for rapid and effective suction under visualization, which is safer.

[0016] (3) When in use, the connector cover can be selectively covered or opened. If the lesion is found during the insertion of the bronchoscope and needs to be treated or biopsied through an electronic soft mirror, it can be performed without removing the device. The connector cover can be opened and the electronic soft mirror can be inserted through the soft mirror inlet. The soft mirror inlet is made of thin-walled high-elastic material and is smaller than the outer diameter of the soft mirror. In this way, the soft mirror can be plugged in and out in a sealed state, ensuring effective ventilation of the patient during anesthesia, which is safer and more effective.

DETAILED DESCRIPTION

[0023] like Figures 1-4 As shown, a multifunctional visual bronchoscope comprises a bronchoscope 1 and a multifunctional visual device 18. A jet ventilation port 6 and a ventilator port 7 are provided on one side of the upper portion of the bronchoscope 1. A flexible end port 9 is provided at the lower end of the bronchoscope 1. Multiple ventilation holes 10 are evenly distributed along the axial direction on the lower sidewall of the bronchoscope 1 to ensure a uniform ventilation effect. The bronchoscope 1 is made of hard metal and has an angled lower end to minimize insertion damage.

[0024] The multifunctional visual device 18 includes an insertion tube 20 located inside the rigid bronchoscope 1. The insertion tube 20 is made of hard metal or hard polymer material and has a double-tube or double-lumen structure.

[0025] The insertion tube 20 includes a suction tube 11 and a data line tube 13. The upper end of the suction tube 11 is connected to a suction connector 17 via a connector socket. The connector 17 is provided with an internal suction port 4, a suction outlet 3, and a suction connector button 2 on its outer side. The lower end of the suction tube 11 defines a suction inlet 12. A suction push rod is located within the suction connector button and passes through a sealing ring. When in its natural position, the push rod and the sealing ring form a tight seal.

[0026] The suction connector button 2 is made of an elastic polymer material and is naturally sealed. The suction outlet 3 can be connected to a negative pressure aspirator to perform negative pressure suction. When suction is required, press the suction connector button 2, the suction push rod and the sealing ring move inward, and the suction outlet 3 is connected to the suction port 4 in the suction connector. The suction speed is adjusted by pressing the connector button 2 with your finger, and sputum, blood, secretions, etc. can be quickly and conveniently suctioned through the suction inlet 12.

[0027] A visual camera 14 is installed at the lower end of the data cable tube 13. This camera 14 is connected to a data extension cable 15 extending from the top of the data cable tube 13, which in turn is connected to a data interface 16. When connected to an image processing system, front-end images can be observed. When the device is assembled with a rigid endoscope and inserted together, it can be placed under visual control at the site of a patient's tracheal or bronchial lesion, while also allowing for visual suction of sputum, blood, or secretions within the trachea or bronchi.

[0028] A flexible joint 21 is fixed to the joint seat by a buckle. The flexible joint 21 is made of silicone or other elastic materials. A flexible mirror inlet 8 is opened in the center of the flexible joint 21. The side wall of the flexible joint 21 is connected to a joint cover 5.

[0029] The jet ventilation interface 6 is connected to the jet ventilator pipeline for jet ventilation during surgery. The ventilator interface 7 is connected to the ventilator pipeline for anesthesia ventilation during surgery. Both jet ventilation and anesthesia ventilation enter the patient's airway through the flexible endoscope outlet and the ventilation side hole to ensure normal breathing and ventilation during surgery.

[0030] The lower outer wall surface of the connector seat is the connector seat outer ring 19, which is designed to be tapered and can be matched with the rigid bronchoscope; if it is found during the insertion of the rigid bronchoscope that the lesion location needs to be treated or biopsied through an electronic soft mirror, it can be done without removing the device, and the electronic soft mirror can be inserted through the soft mirror inlet 8. The soft mirror inlet 8 is a thin-walled, highly elastic material, and its size is smaller than the outer diameter of the soft mirror, so that the soft mirror can be plugged and unplugged in a sealed state; when the electronic soft mirror does not need to be inserted during the insertion of the rigid bronchoscope, the connector cover can be covered to achieve a sealed state, and the rigid bronchoscope can be inserted under visual observation.

[0031] During respiratory surgery, the soft endoscope can be inserted through the soft endoscope inlet 8 and passed through the soft endoscope outlet 9 into the patient's trachea or bronchus for surgery.

[0032] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
