Description

Technical Field

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

[0002] The main body of the fiber bronchoscope is composed of thin glass fibers with good light-conducting properties. Each fiber is coated with a glass film with optical isolation function. A large number of optical fibers are regularly arranged into bundles to guide light and transmit images. Because it is thin, soft and bendable, after insertion, the anatomical structure of the trachea, bronchi, lobes, segments, subsegments and even sub-subsegmental bronchi can be observed, and pathological examination of bronchial and lung biopsies can be performed using cell brushes and biopsy forceps.

[0003] Since fiberoptic bronchoscopy is an invasive procedure, patients may feel uncomfortable, especially when the airway is stimulated during the operation, which may cause coughing, bronchospasm and other reactions, which requires the operator to have superb skills to reduce the patient's discomfort. The field of view of the bronchoscope is limited by the diameter and curvature of the lens, making it difficult to fully observe all the details inside the bronchus. In the case of limited field of view, accurate positioning of the lesion requires the operator to have superb skills and rich experience. Even a slight deviation may lead to operational errors, increasing the risk and discomfort of the patient. For this reason, it is necessary to propose a fiberoptic bronchoscope that can reduce the operator's operating difficulty and make up for the defect of limited field of view to reduce the patient's discomfort. Summary of the invention

[0004] To solve the above problems, the present invention provides a fiber bronchoscope, which aims to reduce the operator's operating difficulty by designing a feedback system that can feedback the depth pressure, effectively compensate for the defect of limited field of view of traditional bronchoscopes, thereby significantly reducing the patient's discomfort and potential risks during the examination.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a fiber bronchoscope, comprising an insertion tube, the bottom end of the insertion tube is connected to a guide joint, the bottom end of the guide joint is connected to a protective lens barrel, the protective lens barrel is provided with an image component for collecting image information of the bronchial end and a light guide component for guiding light for observation, the wall of the insertion tube is provided with a water delivery component for delivering physiological saline, the top end of the insertion tube is fixedly connected to an operating shell, and the operating shell is provided with a steel cable drive component connected to the guide joint for controlling the bending and steering of the insertion tube;

[0006] A pressure sensor is fixedly connected to one end of the goggle barrel away from the insertion tube, and the pressure sensor is electrically connected to an intelligent system for processing the collected pressure data. A vibration button is provided on the outer wall of the operating shell, and the vibration button includes a circular groove opened on the outer wall of the operating shell. An electromagnetic vibrator is fixedly connected to the inner wall of the circular groove, and the electromagnetic vibrator is electrically connected to the intelligent system.

[0007] The technical principles of the above scheme are as follows: the bottom end of the insertion tube can achieve flexible bending and turning through a guide joint, and is remotely controlled by a steel rope drive assembly in the operating shell; the image assembly and the light guide assembly are embedded in the protective goggles, which are responsible for collecting bronchial images and guiding observation light respectively; the wall of the insertion tube is provided with a water delivery assembly for delivering saline to support airway flushing and other operations; at the same time, the pressure sensor connected to the end of the protective goggles monitors the airway pressure in real time and processes the data through an intelligent system; the vibration button on the outer wall of the operating shell has a built-in electromagnetic vibrator, which is connected to the intelligent system for feedback of depth pressure. The overall design aims to improve the accuracy, safety and patient comfort of the examination.

[0008] The above scheme has the following beneficial effects:

[0009] 1. This solution can monitor the pressure changes inside the bronchus in real time. This function is crucial for evaluating the patient's respiratory status and timely detecting possible complications. After the intelligent system processes the collected pressure data, it can issue a warning to the operator in time so that necessary adjustment measures can be taken, such as adjusting the depth or curvature of the insertion tube, thereby reducing the patient's discomfort and ensuring the safety and comfort of the examination process.

[0010] 2. In this solution, the vibration button provided on the outer wall of the operating shell includes an electrical connection between the electromagnetic vibrator and the intelligent system, which provides an intuitive operation feedback mechanism for the operator. When the intelligent system determines that the operation needs to be adjusted based on the data of the pressure sensor or other sensors, the electromagnetic vibrator can generate a vibration signal to remind the operator to pay attention, which can not only achieve timely feedback, so that the operator can receive important operation information without interrupting the line of sight, improving the overall operation efficiency and safety, but also reduce the difficulty of the operator's operation, and move more cautiously and accurately in the patient's body.

[0011] Furthermore, the image component includes a camera fixedly connected to the protective lens barrel, the camera is electrically connected to a power cord, the power cord extends through the insertion tube to the operating shell and is fixedly connected to an image display screen, the image display screen is embedded in the outer wall of the operating shell, and the image display screen and the camera are both electrically connected to the intelligent system.

[0012] Beneficial effects: The camera is fixed in the protective lens tube, which can provide high-definition image information of the bronchial end, helping doctors to diagnose and evaluate the patient's airway condition more accurately. In addition, the power cord connects the camera to the image display screen in the operating shell, ensuring the real-time transmission of image data. The image display screen is embedded in the outer wall of the operating shell, allowing the operator to view the image in real time without additional equipment, improving the convenience and efficiency of operation.

[0013] Furthermore, the light guide assembly includes a transparent light guide window and a glass film made of glass fiber, the glass film is wrapped around the outside of the power cord, and the light guide window is fixedly connected to one end of the protective lens barrel away from the insertion tube.

[0014] Beneficial effects: Glass fiber has good light transmittance and can efficiently transmit light, making the image inside the protective tube brighter and clearer. For the operator, this means that the details inside the bronchus can be observed more easily, thereby improving the accuracy and efficiency of the examination. In addition, the glass fiber membrane wrapped around the outside of the power cord provides an extra layer of protection for the power cord, which not only extends the service life of the power cord, but also reduces equipment failures caused by power cord damage, improving the durability and reliability of the entire fiber bronchoscope.

[0015] Furthermore, the water delivery component includes a water channel opened in the wall of the insertion tube, one end of the water channel is connected to the bottom end of the protective lens barrel, and the other end of the water channel is connected to a booster component for boosting and driving water delivery.

[0016] Beneficial effects: Driven by the booster assembly, rinsing fluids such as saline can enter the bronchus at a higher speed and pressure, thereby more effectively removing secretions, sputum or other foreign matter in the airway. This not only improves the cleanliness of the flushing, but also shortens the time required for flushing, making the entire inspection process more efficient. In addition, since the water channel is directly opened in the wall of the insertion tube and connected to the bottom of the protective lens barrel, the operator can turn on or off the flushing function at any time according to actual needs without interrupting the inspection process, making the operation more flexible and able to adapt to the specific conditions and inspection needs of different patients.

[0017] The cam is connected with the push rod on one side of the push rod, and the cam is provided with a limit block on the other side of the push rod.

[0018] Beneficial effects: Through the cooperation of the booster box and the electric telescopic rod, precise control of the intrabronchial pressure can be achieved. The output end of the electric telescopic rod is fixedly connected with a fixed block and a push rod, and the push rod is connected to the limit block by a first spring. This structure can ensure that when the intrabronchial pressure changes, the push rod can respond flexibly, thereby realizing dynamic adjustment of the pressure. In addition, the electric telescopic rod is connected to the intelligent system signal, so that the booster component can receive and respond to the instructions of the intelligent system in real time, improving the accuracy and safety of the operation. In addition, the intelligent system can automatically adjust the working state of the booster component according to the data of the pressure sensor to ensure that the pressure in the airway remains within an appropriate range.

[0019] Furthermore, the control component includes a second card block rotatably connected to the limiting box body, the second card block is located on a side of the first card block away from the limiting block, and the second card block can contact the first card block.

[0020] Beneficial effects: The addition of the second card block provides a dual limit protection mechanism. When the first card block contacts the limit block, the second card block can serve as a backup to ensure that the device does not exceed the safe operating range when in the extreme position, thereby enhancing the safety of the device. In addition, the second card block can contact the first card block, which means that the operator can adjust the position of the first card block by controlling the second card block, thereby fine-tuning the movement range of the limit block and increasing the flexibility of operation.

[0021] Furthermore, a connecting rod is fixedly connected to the upper part of one end of the second card block away from the first card block, the connecting rod passes through the top wall of the limit box and extends to the outside of the limit box where a button is fixedly connected, a second spring located at the point where the connecting rod and the limit box pass through is fixedly connected to the limit box, one end of the second spring is fixedly connected to the top wall of the limit box and the other end is fixedly connected to the second card block, a displacement sensor is fixedly connected to the second card block, and the displacement sensor is connected to the intelligent system signal.

[0022] Beneficial effects: The button design allows the operator to control directly outside the limit box, providing an intuitive operation interface, simplifying the operation process, making the device easier to use, and the addition of the second spring provides a force feedback mechanism for the system. When the operator presses the button, the second spring can provide resistance to help the operator feel the force of the operation, thereby more accurately controlling the position of the first block and the limit block.

[0023] Furthermore, the shape of the second card block is the same as that of the first card block, both of which are crescent-shaped structures.

[0024] Beneficial effects: The symmetrical design of the crescent-shaped structure helps ensure the coordination and consistency of the two blocks during movement, thereby improving the stability and reliability of the overall mechanical structure. The crescent-shaped structure can disperse the force more evenly and reduce local stress concentration, which helps to extend the service life of the blocks and reduce wear.

[0025] Further, the intelligent system includes a resistance feedback unit and a water delivery unit;

[0026] The resistance feedback unit includes a pressure acquisition module, a processing module and a vibration driving module;

[0027] A pressure acquisition module, used to acquire the pressure signal between the goggles barrel and the patient's bronchial duct through a pressure sensor;

[0028] A processing module, used to amplify the pressure signal collected by the pressure collection module, convert the amplified signal into a pressure data digital signal and then transmit it to the vibration driving module;

[0029] A vibration driving module is used to convert the magnitude of the pressure data into the vibration power of the electromagnetic vibrator and drive the electromagnetic vibrator to vibrate accordingly;

[0030] The water delivery unit includes an identification module and a water delivery drive module;

[0031] An identification module, used for identifying the displacement of the second card block through a displacement sensor;

[0032] The water delivery drive module is used to drive the electric telescopic rod to perform periodic contraction and extension, and correspondingly drive and control the opening and closing of the electric control valve. When the electric telescopic rod contracts, the electric control valve opens, and when the electric telescopic rod extends, the electric control valve closes.

[0033] Beneficial effects: By monitoring the pressure changes in the airway in real time and providing vibration feedback, the operator can more accurately judge the airway status and avoid damage or complications caused by excessive pressure. The vibration feedback mechanism allows the operator to sense the pressure changes in the airway through touch without having to constantly observe the pressure gauge or other indicators, so that the operator can focus more on the inspection process.

[0034] Furthermore, in the identification module, when the displacement sensor collects displacement information of the second card block, it means that a water delivery process has been carried out. At this time, the identification module will transmit a signal to the water delivery drive module, and the water delivery drive module will drive the electric telescopic rod to complete an extension and contraction cycle of the output end.

[0035] Beneficial effects: The displacement of the second card block is monitored in real time by the displacement sensor, and the start and end of the water delivery process can be accurately determined. This precise control ensures that flushing fluids such as saline can be accurately and timely delivered to the inside of the bronchus when needed. In addition, the rapid linkage between the recognition module and the water delivery drive module enables the electric telescopic rod to respond quickly and perform extension and contraction actions, thereby shortening the waiting time of the water delivery process and improving overall efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The following is further described in detail through specific implementation methods:

[0047] Embodiment 1:

[0048] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: a fiber bronchoscope, including an insertion tube 1. In order to realize the multi-directional movement function of the insertion tube 1, the bottom end of the insertion tube 1 is fixedly connected with a guide joint 2 integrally formed with the insertion tube 1. The guide joint 2 is snake-bone-shaped and consists of several layers of movable joints separated by gaps. The movable joints are all penetrated with steel wires along four directions. The top ends of the steel wires penetrate the insertion tube 1 and extend to the top of the insertion tube 1. An operating shell 4 is fixedly connected to the top of the insertion tube 1. The corresponding four steel wires in the operating shell 4 are respectively fixedly connected with motors by screws. The operating shell 4 is equipped with means for separately controlling the power of the motors to realize multi-directional bending of the guide joint 2. Through the different extension and contraction degrees of the four steel wires, different directions of the several movable joints on the guide joint 2 show different contraction degrees.

[0049] Specific as Figure 4As shown, the bottom end of the guide joint 2 is fused with a protective lens barrel 3, and the protective lens barrel 3 is provided with an image component for collecting image information of the bronchial end and a light guide component for guiding light for observation, wherein the image component includes a camera 7 fixedly connected to the protective lens barrel 3 by a pin, and the camera 7 is electrically connected to a power cord 8, and the power cord 8 extends along the insertion tube 1 to the operating shell 4 and is electrically connected to an image display screen 9, which is embedded in the outer wall of the operating shell 4, and the image display screen 9 is electrically connected to an intelligent system, and the camera 7 is also electrically connected to the intelligent system. When the insertion tube 1 enters the patient's bronchial duct through the patient's oral or nasal cavity, the camera 7 begins to capture detailed image information of the bronchial end, and these high-definition image information are transmitted to the image display screen 9 in the operating shell 4 in real time through the power cord 8, so that the doctor can clearly observe the internal situation of the bronchus from the outside, including any potential abnormalities, inflammations, masses or narrow areas. The image display function is not only conducive to the doctor's diagnosis of the patient's bronchial condition, but also conducive to the doctor's moving the insertion tube 1 according to the image to better diagnose the patient's condition.

[0050] The light guide assembly includes a transparent light guide window 10 and a glass film 11 made of glass fiber. The glass film 11 is wrapped around the outside of the power cord 8. The light guide window 10 is fixedly connected to the bottom end of the goggle tube 3 by a snap-on structure. The glass film 11 serves as an efficient optical fiber channel. The glass fiber itself has excellent light guiding properties and can transmit light along the fiber axis while maintaining the intensity and directionality of the light. When light from an external light source (such as an LED lamp) shines on the glass film 11, the light will be captured by the glass fiber and transmitted along its length until it reaches the vicinity of the light guide window 10. At the light guide window 10, the light is further guided and focused into the inside of the bronchus, providing doctors with a bright and clear field of view, thereby improving the accuracy and safety of bronchoscopic examination or treatment.

[0051] like Figure 2 and Figure 3 As shown, a water channel 12 is provided in the wall of the insertion tube 1, one end of the water channel 12 is connected to the bottom end of the protective lens tube 3, and the other end of the water channel 12 is connected to the top of the insertion tube 1 and connected to a pressurizing box 13, and the pressurizing box 13 is fixedly connected to the operating shell 4, as shown in FIG. Figure 3As shown, the top wall of the booster box 13 is fixedly connected with an electric telescopic rod 14 by bolts, and the output end of the electric telescopic rod 14 is fixedly connected with a fixed block 15 by a coupling, and a push rod 16 is welded on the bottom surface of the fixed block 15. A limit block 17 is slidably sleeved on the end of the push rod 16 away from the fixed block 15, and a conical striker 18 is fixedly connected to the side of the limit block 17 away from the push rod 16. The shape of the striker 18 fits the shape of the connection between the booster box 13 and the water channel 12. When the striker 18 moves downward, it will compress the volume between the striker 18 and the upper opening of the water channel 12, forming a pump hydraulic force formed by volume compression. This pump hydraulic force has the characteristics of high pressure and high speed, and can quickly push the fluid through the water channel 12 to achieve rapid liquid transmission or flushing function. The pumped physiological saline is used to flush secretions, blood or other impurities in the bronchus to ensure a clear surgical field of view.

[0052] Specific as Figure 3 As shown, a limit box 20 connected to the corresponding limit block 17 position is welded to the right side wall of the boost box 13, a first spring 19 is fixedly connected between the limit block 17 and the fixed block 15, a first clamping block 21 is rotatably connected to the limit box 20 through a bearing, and the first clamping block 21 is a crescent-shaped structure, and the left end of the first clamping block 21 is located in the moving track of the limit block 17. The design of the left end of the first clamping block 21 can cleverly fit with the side of the limit block 17 to form a temporary locking mechanism, which also has the effect of energy storage. Since the left end of the first clamping block 21 is subjected to the downward force of the limit block 17, the first clamping block 21 will show a tendency of rotating counterclockwise downward at the left end. At this time, after the rotation limit is arranged at the right end of the first clamping block 21, when the right end limit When the position is released, the elastic potential energy stored in the first spring 19 due to the previous compression is quickly released, pushing the limit block 17 and the push rod 16 and the fixed block 15 connected thereto to quickly return to the initial position, and the limit block 17 moves a certain distance and then breaks away from the contact with the first clamping block 21, so that the physiological saline is pumped into the liquid passage tube. Through the ingenious combination of the first clamping block 21 and the limit block 17, and the energy storage and release mechanism of the first spring 19, this locking mechanism in the booster box 13 not only realizes the precise control and stable limiting of the push rod 16 and the impact rod 18, but also improves the response speed and stability of the system through the efficient energy storage and release mechanism, providing more reliable and efficient fluid transmission and flushing functions for minimally invasive surgeries such as bronchoscopy.

[0053] A second clamping block 23 is also rotatably connected to the limit box 20 through a bearing. The second clamping block 23 has the same shape as the first clamping block 21. The second clamping block 23 is located on the right side of the first clamping block 21 and can contact the first clamping block 21. A connecting rod 24 is fixedly connected to the upper part of one end of the second clamping block 23 away from the first clamping block 21. The connecting rod 24 penetrates the top wall of the limit box 20 and extends to the outside of the limit box 20 and is fixedly connected to a button 25. A second spring 26 located at the penetration point between the connecting rod 24 and the limit box 20 is fixedly connected to the limit box 20. One end of the second spring 26 is fixedly connected to the inner top wall of the limit box 20 and the other end is fixedly connected to the second clamping block 23. When the button 25 is pressed, the connecting rod 24 moves downward, driving the second block 23 to rotate, so that the left end thereof gradually separates from the right end of the first block 21. At this time, the left end of the first block 21 originally fits with the side of the limit block 17, and the separation of the second block 23 will cause the first spring 19 to release the stored pressure, so that the limit block 17 quickly moves downward, realizing the unlocking function of the second block 23. The design of the button 25 enables the doctor to independently control the delivery of saline, reduce the difficulty of operating the equipment, and improve the stability of the operation.

[0054] In order to further reduce the difficulty of operation, a displacement sensor 27 is fixedly connected to the second card block 23 by screws. The displacement sensor 27 is connected to the intelligent system signal. When the doctor presses the button 25 to pump saline, the displacement sensor 27 can collect the displacement information of the second card block 23 and send a signal representing "water replenishment is needed" to the intelligent system.

[0055] For the water replenishment operation, the side wall of the booster box 13 is also fixedly connected with a water storage box 22 connected to the corresponding position of the impact rod 18, and the connection between the water storage box 22 and the booster box 13 is fixedly connected with an electric control valve 28 by screws. The electric control valve 28 is connected with the intelligent system signal. The electric control valve 28 is controlled by the intelligent system and opens when receiving the signal of "need to replenish water", otherwise it is continuously closed, so as to realize the intelligent replenishment of physiological saline. The electric telescopic rod 14 is connected with the intelligent system signal. When the electric telescopic rod 14 is lifted by the signal control of the intelligent system, the electric telescopic rod 14 lifts the fixed block 15 up. This action drives the limit block 17 and the conical impact rod 18 to rise together through the connection of the push rod 16 and the limit block 17, and the water in the water storage box 22 begins to gradually flow into the water channel 12, preparing for the next pump hydraulic operation. In this process, the water storage box 22 plays the role of providing a stable source of fluid for the system, ensuring the continuity and reliability of the operation.

[0056] The intelligent system controls the electric telescopic rod 14 accurately and flexibly. It can preset the lifting speed, stroke and operating frequency of the electric telescopic rod 14 according to the needs of the operation to achieve precise adjustment of the fluid transmission and flushing functions. For example, when a large amount of secretions in the bronchus needs to be quickly flushed, the intelligent system can control the electric telescopic rod 14 to work at a faster speed and a larger stroke; when delicate operations are required, such as removing tiny lesions and slow flushing, the lifting speed and operating frequency of the electric telescopic rod 14 can be reduced to reduce damage to surrounding tissues.

[0057] Due to the characteristics of bronchial stenosis, there are limitations in judging the insertion direction of the insertion tube 1 by only using an image. Therefore, a pressure sensor 5 is welded to one end of the protective lens tube 3 away from the insertion tube 1. The pressure sensor 5 is electrically connected to the intelligent system, and a vibration button 6 is provided on the outer wall of the operating shell 4. The vibration button 6 includes a circular groove 601 opened on the outer wall of the operating shell 4. The inner wall of the circular groove 601 is provided with an electromagnetic vibrator 602 through a screw. The electromagnetic vibrator 602 is also electrically connected to the intelligent system. When the doctor moves the insertion tube 1 based on the image displayed on the image display screen 9, when the doctor makes a mistake and the protective lens tube 3 contacts the inner wall of the patient's bronchus, the pressure sensor 5 will quickly collect the pressure change signal generated by this contact and transmit it to the intelligent system. After receiving this signal, the intelligent system will immediately analyze and process it to determine the degree of contact between the protective lens tube 3 and the inner wall of the bronchus and the possible risks. At the same time, the electromagnetic vibrator 602 in the vibration button 6 on the outer wall of the operating shell 4 will also start working according to the instructions of the intelligent system. The electromagnetic vibrator 602 generates a weak vibration and transmits the vibration to the doctor's hand through the tight connection with the operating shell 4. This vibration serves as a tactile feedback to remind the doctor that the goggle tube 3 has touched the inner wall of the bronchus and needs to adjust the direction or force of the insertion tube 1 to avoid unnecessary damage to the patient.

[0058] Embodiment 2:

[0059] As attached Figure 5 As shown, the difference from Example 1 is that the intelligent system includes a resistance feedback unit and a water delivery unit.

[0060] The resistance feedback unit includes a pressure acquisition module, a processing module and a vibration driving module.

[0061] The pressure acquisition module acquires the pressure signal between the goggles barrel 3 and the patient's bronchial duct through the pressure sensor 5, and transmits the pressure signal to the processing module for signal processing.

[0062] The processing module amplifies the pressure signal collected by the pressure collection module, converts the amplified signal into a pressure data digital signal and transmits it to the vibration driving module.

[0063] The vibration driving module converts the magnitude of the pressure data into the vibration power of the electromagnetic vibrator 602 and drives the electromagnetic vibrator 602 to perform vibration driving accordingly.

[0064] The water delivery unit includes an identification module and a water delivery drive module.

[0065] The identification module is used to identify the displacement of the second card block 23 through the displacement sensor 27. When the displacement sensor 27 collects the displacement information of the second card block 23, it means that a water delivery process has been carried out. At this time, the identification module will transmit a signal to the water delivery drive module.

[0066] The water delivery drive module receives the signal transmitted by the identification module and completes an extension and contraction cycle of the output end of the electric telescopic rod 14. Correspondingly, when the electric telescopic rod 14 contracts, the electric control valve 28 is opened, and when the electric telescopic rod 14 extends, the electric control valve 28 is closed to achieve the effect of water replenishment.

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
