[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Bronchoscopy has become an indispensable diagnostic and treatment tool in clinical practice, especially for respiratory diseases. Bronchoscopy can be used for bronchoalveolar lavage, removal of foreign bodies from the airways, treatment of bronchopleural and bronchoesophageal fistulas, treatment of chronic obstructive pulmonary disease, assisted intubation and ventilation for difficult airways, adjunctive treatment of airway stenosis, ultrasound-assisted tracheal wall radioactive seed implantation, and bronchoscopic argon gas knife thermal ablation combined with cryosurgery for the treatment of airway tumors.

[0037] It is widely used in the diagnosis and treatment of various diseases, including pulmonary infections, tuberculosis, diffuse diseases, lung cancer, chronic obstructive pulmonary disease, airway foreign bodies, and bronchopleural fistulas. It has a long history of clinical application due to its ability to visually assess airway lesions and directly intervene.

[0038] Among them, bronchoscopy is an invasive examination or treatment method. During this process, the insertion of bronchoscope into the airway may damage the mucosa and there is a risk of bleeding.

[0039] To solve the above technical problems, please refer to Figures 1 to 5 The present application provides a bronchoscope assembly 100, which may include a driving member, an air delivery device, an air delivery tube 120, an air bag, a main tube 140 and an image acquisition device.

[0040] Specifically, the driving member includes a shell, and the shell includes a top wall 111, a bottom wall 112 and a side wall 113. The top wall 111 and the bottom wall 112 are arranged opposite to each other, and the side wall 113 is arranged around the circumferential side of the top wall 111 and the bottom wall 112. The side wall 113 is formed into a ring shape, and together with the top wall 111 and the bottom wall 112, it defines a closed space air cavity 114. A plurality of through holes 115 are provided on the side wall 113, and the plurality of through holes 115 are arranged at circumferential intervals on the side wall 113.

[0041] Among them, the top wall 111, the bottom wall 112 and the side wall 113 can be made of rubber or silicone material, the top wall 111, the bottom wall 112 and the side wall 113 can be an integrally molded part, the connection position between the top wall 111 and the side wall 113 is rounded, and the connection position between the bottom wall 112 and the side wall 113 is rounded.

[0042] One end of the gas pipe 120 is connected to the gas delivery device, and the other end is connected to the air cavity 114. Multiple air bags correspond one to one with multiple through holes 115. The air bags include a bag body 132 and a tube body 131. One end of the tube body 131 is connected to the gas delivery device, and the other end is connected to the bag body 132. The bag body 132 includes a filled state and an exhausted state. When the bag body 132 is in the filled state, the bag body 132 is blocked in the through hole 115. When the bag body 132 is in the exhausted state, the gas in the air cavity 114 can be discharged through the through hole 115. It should be noted that the volume of the bag body 132 when it is in the filled state is greater than the volume of the bag body 132 when it is in the exhausted state.

[0043] Among them, the gas delivery device is used to deliver gas to the gas delivery pipe 120, and to deliver or extract gas to the airbag. The gas delivery device may include an oxygen storage device, an air pump and an electromagnetic valve. The electromagnetic valve is used to control the conduction and disconnection between the gas delivery pipe 120 and the airbag and the oxygen storage device. The air pump is used to control the gas delivery to the gas delivery pipe 120, and control the gas delivery or extraction into the airbag. Specifically, the oxygen storage device may be an oxygen tank, the gas delivery pipe 120 may correspond to an electromagnetic valve, and each airbag corresponds to an electromagnetic valve.

[0044] In order to facilitate the insertion of the bronchoscope assembly 100 into the human body, the air supply tube 120 and the tube body 131 are both inserted into the main tube 140, which can avoid tube entanglement and reduce the resistance when the bronchoscope assembly 100 is inserted into the human body.

[0045] Among them, the air pipe 120 needs to transport oxygen into the air cavity 114 space, and the airbag only needs to block the through hole 115. The amount of oxygen transported by the air pipe 120 is greater than the amount of oxygen transported by the airbag. The aperture of the air pipe 120 is larger than the diameter of the main pipe 140 of the airbag. The air pipe 120 is arranged in the middle position of the main pipe 140, and multiple tube bodies 131 are arranged on the circumferential outside of the main pipe 140.

[0046] The image acquisition device is disposed on the outer surface of the housing. The image acquisition device may be a camera 150 for acquiring images of the interior of the airway.

[0047] In this way, the medical staff inserts the bronchoscope assembly 100 into the patient's airway and obtains the image of the inside of the airway through the camera 150 on the outer shell. When the image captured by the camera 150 is close to the inner wall of the airway, the driving member and the through hole 115 on the side closer to the airway and the corresponding bag 132 can be adjusted to the exhaust state, so that the through hole 115 on the side closer to the airway is opened, and the oxygen in the air cavity 114 is sprayed into the airway through the through hole 115. Under the action of the reaction force, the driving member moves toward the other side. When the driving member returns to the middle position of the airway, the bag 132 is adjusted to the filled state and the corresponding through hole 115 is blocked. Therefore, by setting a plurality of bags 132 and through holes 115 that cooperate with each other, the forward direction of the driving member can be adjusted, thereby avoiding collision between the bronchoscope assembly 100 and the patient's airway and reducing the occurrence of damage to the inner wall of the patient's airway.

[0048] Furthermore, the side wall 113 may include a first side wall 1131, a second side wall 1132, a third side wall 1133 and a fourth side wall 1134 connected in sequence, the connection position between the first side wall 1131 and the second side wall 1132 is set with a rounded corner, the connection position between the second side wall 1132 and the third side wall 1133 is set with a rounded corner, the connection position between the third side wall 1133 and the fourth side wall 1134 is set with a rounded corner, and the connection position between the fourth side wall 1134 and the first side wall 1131 is set with a rounded corner.

[0049] In this way, it is possible to avoid the situation where the inner wall of the airway is damaged due to the sharp edges and corners of the connection.

[0050] The first side wall 1131 and the third side wall 1133 are arranged opposite to each other, the second side wall 1132 and the fourth side wall 1134 are arranged opposite to each other, and the multiple through holes 115 may include a first through hole 1151, and the first through hole 1151 is arranged on the first side wall 1131. The number of the first through holes 1151 can be multiple, specifically, the number of the first through holes 1151 is two.

[0051] The plurality of through holes 115 may further include a second through hole 1152 . The second through hole 1152 is disposed on the second side wall 1132 . The number of the second through holes 1152 may be multiple. Specifically, the number of the second through holes 1152 is two.

[0052] The plurality of through holes 115 may further include a third through hole 1153 . The third through hole 1153 is disposed on the third side wall 1133 . The number of the third through holes 1153 may be multiple. Specifically, the number of the third through holes 1153 is two.

[0053] The plurality of through holes 115 may further include a fourth through hole 1154 . The fourth through hole 1154 is disposed on the fourth side wall 1134 . The number of the fourth through holes 1154 may be multiple. Specifically, the number of the fourth through holes 1154 is two.

[0054] With the direction of the first side wall 1131 as the front, the direction of the third side wall 1133 as the back, the direction of the second side wall 1132 as the left, and the direction of the fourth side wall 1134 as the right, the two first through holes 1151 are respectively located in the left half and the right half of the first side wall 1131, the two third through holes 1153 are respectively located in the left half and the right half of the third side wall 1133, the two second through holes 1152 are respectively located in the front half and the back half of the second side wall 1132, and the two fourth through holes 1154 are respectively located in the front half and the back half of the fourth side wall 1134.

[0055] In this way, by setting multiple first through holes 1151, multiple second through holes 1152, multiple third through holes 1153 and multiple fourth through holes 1154, the bronchoscope assembly 100 can realize operations such as forward advancement, backward advancement, left translation, right translation, left turn, right turn, left quick turn, right quick turn, and emergency stop.

[0056] Specifically, the bronchoscope assembly 100 can be pushed back by blocking the second through hole 1152 , the third through hole 1153 , and the fourth through hole 1154 with the airbag and opening the two first through holes 1151 .

[0057] The bronchoscope assembly 100 can be advanced forward by blocking the first through hole 1151 , the third through hole 1153 , and the fourth through hole 1154 through the airbag and opening the two second through holes 1152 .

[0058] It can be understood that in some other embodiments, the number of first through holes 1151 can also be three, four, etc., the number of second through holes 1152 can also be three, four, etc., the number of third through holes 1153 can also be three, four, etc., and the number of fourth through holes 1154 can also be three, four, etc.

[0059] In some embodiments of this application, please refer to Figure 4 and Figure 5 The driving member also includes a plurality of extension tubes 160, which correspond one-to-one to the plurality of through holes 115. The extension tubes 160 include a first end and a second end relative to each other. The first end is connected to the inner surface of the side wall 113 and is covered in the through hole 115. The capsule 132 is located in the extension tube 160.

[0060] Therefore, by setting the extension tube 160 to provide a placement position for the balloon body 132 of the airbag, the movement of the balloon body 132 inside the air cavity 114 is reduced, and after the balloon body 132 is inflated to be in a full state, the balloon body 132 can block the through hole 115.

[0061] Furthermore, the second end is provided with an inward-folded flange 161. It can be understood that by providing the inward-folded flange 161, the inner diameter of the second end becomes smaller. In this way, even if the capsule 132 is in the exhaust state and the volume is small, the capsule 132 still cannot enter the air cavity 114 through the second end, thereby making the position of the capsule 132 stable in the extension tube 160, ensuring the stability of the position of the capsule 132.

[0062] Furthermore, the extension tube 160 includes a guide section connected to the side wall 113. The inner diameter of the guide section gradually decreases in the direction toward the side wall 113. In this way, when the capsule 132 is in the exhaust state, the gas in the air cavity 114 will accelerate after passing through the guide section, providing greater thrust for the movement of the driving member.

[0063] In some embodiments of the present application, the driving member may further include a lighting lamp 170, which is arranged on the outer surface of the shell. Specifically, the lighting lamp 170 is arranged on the outer surface of the side wall 113. The number of the lighting lamps 170 can be multiple, and the multiple lighting lamps 170 are evenly spaced in the circumferential direction of the side wall 113.

[0064] Specifically, the number of the lighting lamps 170 may be 16, with four lighting lamps 170 provided on the first side wall 1131 , four lighting lamps 170 provided on the second side wall 1132 , four lighting lamps 170 provided on the third side wall 1133 , and four lighting lamps 170 provided on the fourth side wall 1134 .

[0065] In this way, the illumination lamp 170 is provided to provide a light source for the bronchoscope assembly 100 to acquire an image, thereby ensuring clarity of the image.

[0066] In some embodiments of the present application, the driving member may further include a universal wheel, which is arranged on the outer shell. Specifically, the universal wheel is arranged on the outer surface of the bottom wall 112. In this way, by setting the universal wheel, the static friction between the driving member and the inner wall of the airway can be prevented from being converted into sliding friction, which can further prevent the inner wall of the airway from being damaged.

[0067] Furthermore, the housing is provided with a sinking groove, the universal wheel is provided in the sinking groove, and part of the universal wheel is located in the sinking groove. In this way, on the one hand, the volume of the entire driving member can be reduced, and on the other hand, the use of the universal wheel can be guaranteed.

[0068] In some embodiments of the present application, the bronchoscope assembly 100 may further include a control device, which is communicatively connected to the gas delivery device and the image acquisition device respectively.

[0069] Specifically, the control device is electrically connected to the air pump and the solenoid valve of the air delivery device, and the control device is electrically connected to the camera 150 .

[0070] See also Figure 3 The signal line 181 and the power supply line 182 of the camera 150 are both arranged in the main pipe 140.

[0071] Among them, the control device may include a signal processing device and a control panel. The control panel can control the start and stop of the solenoid valve and air pump corresponding to the airbag and the air pipe 120. The signal processing device is used to collect image information and analysis of the camera 150.

[0072] In some embodiments of this application, please refer to Figure 1 and Figure 2 A camera mounting portion 151 is provided on the top wall 111, and four cameras 150 are provided on the camera mounting portion 151. The four cameras 150 are evenly spaced around the circumference of the camera mounting portion 151. Specifically, the shooting directions of the four cameras 150 are respectively facing the front left, the rear left, the front right and the rear right.

[0073] In some embodiments of the present application, the outer end of the bronchoscope assembly 100 is also connected to a display, which is used to display images taken by the camera 150.

[0074] The specific operation process of medical staff includes the following steps:

[0075] Step 1: A 3D map of the trachea and bronchi and lesion location data is generated based on bronchoscopic image data of the patient's trachea and bronchi and lungs. A convolutional neural network AI algorithm is used to automatically plan the path and locate the lesion. This information is uploaded to the human-computer interaction planning and display system.

[0076] Step 2: Based on the information obtained, the path of travel and the location of the lesion are given.

[0077] Step 3: The medical staff determines whether the access path and the lesion location are feasible. If feasible, the driving member is started through the control panel.

[0078] Step 4: The driving member moves along the travel path until it reaches the lesion location.

[0079] Step 5: If the direction of travel deviates or there is a risk of hitting the inner wall of the airway during travel, medical personnel can control the translation and rotation of the drive component through the control panel and take over the control system through the control panel.
