Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fiberoptic bronchoscope. Background Technology

[0002] Fiberoptic bronchoscopy is an endoscopic examination technique with a wide range of clinical applications. It is primarily used to detect diseases deep within the trachea, bronchi, and lungs, enabling diagnosis and treatment without external trauma, thus sparing many patients the pain of open surgery. Fiberoptic bronchoscopy is suitable for observing lesions in the lobes, segments, and subsegments of the bronchi, for biopsy sampling, and for bacteriological and cytological examinations. Combined with a video system, it can be used for photography, teaching, and dynamic recording, enabling the detection of early lesions. It is a valuable and sophisticated instrument for the research of bronchial and lung diseases.

[0003] Current fiberoptic bronchoscopes generally do not come with irrigation tubing. Because fiberoptic bronchoscopes do not integrate irrigation tubing, doctors need to prepare additional irrigation fluid and related equipment when performing procedures such as bronchial lavage or bronchoalveolar lavage. This not only increases the complexity of the procedure but may also prolong the operation time and increase patient discomfort. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a bronchoscope that can solve the problem of bronchoscopes not having flushing tubing.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A fiberoptic bronchoscope, comprising:

[0007] A functional tube, wherein a negative pressure tube and a flushing tube are provided inside the functional tube;

[0008] The operating handle is equipped with a control knob, a flushing button, a negative pressure interface, and a flushing interface. The negative pressure interface is used to connect to an external negative pressure air source, and the flushing interface is used to connect to an external flushing source.

[0009] The negative pressure tube and the flushing tube are both located inside the functional tube. The negative pressure tube passes through the inside of the operating handle and communicates with the negative pressure interface. The flushing tube passes through the inside of the operating handle and communicates with the flushing interface. The control knob is used to control the direction of the negative pressure tube and the flushing tube located inside the functional tube. The flushing button is used to control the on / off state of the flushing tube.

[0010] Furthermore, the operating handle includes a handheld part, an operating part, and an external part. One end of the handheld part is connected to the functional tube, and the other end is connected to the operating part. The control knob and the flushing button are located on the operating part, and the negative pressure port and the flushing port are located on the external part. The external part is located on the side of the operating part away from the handheld part.

[0011] Furthermore, the control knob and the flushing button are located on two adjacent sides of the operating section, respectively.

[0012] Furthermore, the external connector and the flushing button are located on the same side of the operating handle.

[0013] Furthermore, the external part is columnar, with one end of the external part fixedly connected to the operating part, and the other end inclined away from the operating handle.

[0014] Furthermore, the negative pressure port and the flushing port are arranged in parallel.

[0015] Furthermore, the orientation of the negative pressure port and the flushing port relative to the external part is the same as the orientation of the control knob relative to the operating part.

[0016] Furthermore, a trigger is provided on the outside of the control knob, and the trigger extends to the outside of the operating handle.

[0017] Furthermore, the trigger is provided in multiple parts, all of which are fixedly connected to the control knob and are evenly distributed along the circumference of the control knob.

[0018] Furthermore, the negative pressure interface is a Luer interface.

[0019] In summary, the fiberoptic bronchoscope provided by this utility model has the following technical effects:

[0020] 1. Because the bronchoscope integrates an irrigation tubing, users can directly perform bronchial irrigation or bronchoalveolar lavage through the bronchoscope without the need for additional irrigation fluid and related equipment.

[0024] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0025] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] See Figure 1 This utility model discloses a fiberoptic bronchoscope, including a functional tube 1 and an operating handle 2. The functional tube 1 contains a negative pressure tube and a flushing tube. The operating handle 2 has a control knob 221, a flushing button 222, a negative pressure interface 231, and a flushing interface 232. The negative pressure interface 231 is used to connect to an external negative pressure air source, and the flushing interface 232 is used to connect to an external flushing source. Both the negative pressure tube and the flushing tube are located inside the functional tube 1. The negative pressure tube passes through the inside of the operating handle 2 and communicates with the negative pressure interface 231, and the flushing tube passes through the inside of the operating handle 2 and communicates with the flushing interface 232. The control knob 221 controls the direction of the negative pressure tube and the flushing tube located inside the functional tube 1, and the flushing button 222 controls the on / off state of the flushing tube.

[0029] Specifically, the functional tube 1 contains two independent pipes: a negative pressure pipe and a flushing pipe. These two pipes run through the entire functional tube 1 and extend into the operating handle 2. The negative pressure pipe connects to a negative pressure interface 231 located on the outside of the handle via the inside of the operating handle 2. This interface is used to connect to an external negative pressure air source. Similarly, the flushing pipe connects to a flushing interface 232 via the inside of the operating handle 2. This interface is used to connect to an external flushing liquid source. The operating handle 2 also has a control knob 221 for controlling the direction of the negative pressure pipe and the flushing pipe within the functional tube 1, and a flushing button 222 for controlling the on / off state of the flushing pipe.

[0030] The working principle of the above structure:

[0031] When negative pressure suction is required, the user can prepare the device by connecting the negative pressure interface 231 to an external negative pressure air source. The direction of the negative pressure tube can be adjusted by rotating the control knob 221 on the operating handle 2 to point it to the desired position. Once the direction is adjusted, activating the external negative pressure source will begin the suction process, helping to clear secretions or other substances from the respiratory tract.

[0032] For rinsing needs, the user first ensures that the rinsing interface 232 is correctly connected to the external rinsing fluid source. Pressing the rinsing button 222 on the operating handle 2 opens the rinsing pipeline, allowing the rinsing fluid to flow through the rinsing pipe and finally spray out from the front end of the functional tube 1 to clean or flush the target area. Pressing the rinsing button 222 again closes the rinsing function and stops the fluid flow.

[0033] It should be noted that, since this application does not involve the imaging fiber or the specific turning structure of the end of the functional tube 1, the imaging fiber can be a conventional imaging fiber installed inside the functional tube 1. The structure for controlling the turning of the end of the functional tube 1 can be a steel strand pulled to turn the end of the functional tube 1. The other pipes installed inside the functional tube 1 will also turn synchronously. The steel strand is controlled by the rotation of the control knob 221 to control the tightening and loosening of the steel strand, thereby controlling the turning of the end of the functional tube 1. This is also a conventional technology and will not be described in detail here.

[0034] In some embodiments, the operating handle 2 includes a handheld part 21, an operating part 22, and an external part 23. One end of the handheld part 21 is connected to the function tube 1, and the other end is connected to the operating part 22. The control knob 221 and the flushing button 222 are located on the operating part 22, and the negative pressure port 231 and the flushing port 232 are located on the external part 23. The external part 23 is located on the side of the operating part 22 away from the handheld part 21.

[0035] Specifically, in existing technologies, the negative pressure port 231 or flushing port 232 is generally located in the middle of the bronchoscope. During user handling, the negative pressure port 231 or flushing port 232 in the middle needs to be connected to corresponding tubing. This external tubing can interfere with the user's hand, resulting in a poor user experience. The bronchoscope includes a handheld part 21, an operating part 22, and an external connection part 23. One end of the handheld part 21 is connected to the functional tube 1, and the other end is connected to the operating part 22. The handheld part 21 is used for gripping during use. The operating part 22 is located between the handheld part 21 and the external connection part 23. The control knob 221 and the flushing button 222 are located on the operating part 22, allowing medical personnel to control the control knob 221 and the flushing button 222 using their thumb, index finger, and middle finger while holding the handheld part 21. The external connection part 23 is located on the side of the operating part 22 away from the handheld part 21, that is, at the tail end of the entire operating handle 2. The negative pressure interface 231 and the flushing interface 232 are located on the external connection part 23 for corresponding connection to external negative pressure air source and flushing fluid source. Because the external connection part 23 is located at the tail end of the operating handle 2, the user's hand will not come into contact with the tubing connected to the negative pressure interface 231 or the flushing interface 232, thereby avoiding the operational interference caused by the external tubing connected to the middle interface of the traditional fiberoptic bronchoscope.

[0036] In some embodiments, the control knob 221 and the flush button 222 are located on two adjacent sides of the operating section 22, respectively.

[0037] Specifically, the control knob 221 and the rinse button 222 are located on two adjacent sides of the operating part 22. When the user holds the hand part 21, the thumb can be naturally placed on one side of the operating part 22 to operate the control knob 221, while the index or middle finger can easily reach the rinse button 222 on the adjacent side. This layout allows the user to complete all necessary operations without changing the hand position, greatly improving the smoothness and efficiency of operation.

[0038] In some embodiments, the external part 23 and the flush button 222 are located on the same side of the operating handle 2.

[0039] Specifically, the external connection part 23 and the flushing button 222 are located on the same side of the operating handle 2. Correspondingly, the external tubing for both is also concentrated on the same side, making it convenient for users to manage and organize these tubing. This avoids the situation where, when the user moves the bronchoscope and the external tubing comes from different directions, different tubing needs to be pulled and pushed, which would generate resistance in multiple directions and affect operational accuracy. The design of the external tubing being on the same side avoids this situation, ensuring smoother movement of the bronchoscope. With the external tubing on the same side, the user can fully anticipate the direction of possible resistance during operation, thereby improving operational accuracy. In addition, the centralized arrangement of tubing reduces the risk of tangling and confusion, making the operating environment cleaner and more orderly.

[0040] In some embodiments, the external part 23 is columnar, with one end of the external part 23 fixedly connected to the operating part 22, and the other end inclined in a direction away from the operating handle 2.

[0041] Specifically, the external part 23 is columnar, with one end fixedly connected to the operating part 22 and the other end inclined away from the operating handle 2. That is, the external part 23 extends away from the operating handle 2. Correspondingly, the tubing (such as negative pressure tubing and flushing tubing) connected to the negative pressure interface 231 and the flushing interface 232 is introduced from the inclined external part 23. In other words, the external tubing will be further away from the user's gripping hand, thereby reducing the possibility of the external tubing coming into contact with the user's hand and forearm.

[0042] In some embodiments, to prevent interference between the external pipelines of the negative pressure port 231 and the flushing port 232, the negative pressure port 231 and the flushing port 232 are arranged in parallel.

[0043] In some embodiments, the orientation of the negative pressure port 231 and the flushing port 232 relative to the external part 23 is the same as the orientation of the control knob 221 relative to the operation part 22.

[0044] Specifically, the orientation of the negative pressure port 231 and the flushing port 232 is the same as the orientation of the control knob 221 relative to the operating part 22. This ensures that the external pipes of the negative pressure port 231 and the flushing port 232 are led out from the same direction. Furthermore, when the user holds the control knob 221 normally, only the thumb is in the direction of the control knob 221 relative to the operating part 22, while most of the palm and forearm are in the opposite direction. This further reduces the possibility of the external pipes interfering with the user's palm and forearm, ensuring smooth and comfortable operation.

[0045] In some embodiments, to facilitate operation of the control knob 221 by the user using only the thumb, a trigger 2211 is provided on the outside of the control knob 221, and the trigger 2211 extends to the outside of the operating handle 2.

[0046] Furthermore, multiple triggers 2211 are provided, all of which are fixedly connected to the control knob 221 and are evenly distributed along the circumference of the control knob 221. This structure ensures that triggers 2211 are readily available within the thumb's range of motion, facilitating thumb-driven operation and further enhancing the effectiveness of operating the control knob 221 solely with the thumb.

[0047] In some embodiments, to facilitate the connection between the negative pressure interface 231 and the negative pressure pipeline, and to ensure the applicability of the negative pressure interface 231, the negative pressure interface 231 is a Luer interface.

[0048] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
