Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, in particular to a disposable pharyngeal and bronchial electronic soft endoscope. Background Art

[0002] A flexible bronchoscope is a medical device that combines endoscopic and electronic imaging technologies. It consists of core components such as the bronchoscope, light source, camera system, and operating channel. The flexible bronchoscope is inserted into the airway through the nasal or oral cavity. A front-end camera and LED light source are used to capture and transmit high-definition images to a display screen in real time, assisting doctors in observing, diagnosing, and treating respiratory diseases. Featuring high definition, minimally invasive, and multifunctional features, it is widely used in diagnosis, treatment, and emergency settings, with the technology continuing to evolve towards intelligence and precision.

[0003] However, we found in actual use that the existing electronic bronchoscope needs to be used repeatedly.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-12 The present invention provides a technical solution: a disposable pharyngeal bronchoscope electronic soft endoscope, including an operating system 1, a steering system 27, a sheath tube 2 and a sheath hole 3, and also includes:

[0037] There are multiple connecting plates 4, each of which is arranged at one end of the sheath tube 2 close to the operating system 1, and is used to connect the operating system 1 and the sheath tube 2. The bottom end of the operating system 1 is provided with connecting grooves 5 for use with the multiple connecting plates 4. The multiple connecting plates 4 are used to cooperate with the corresponding connecting grooves 5 to drive the disassembly and assembly of the sheath tube 2 and the operating system 1;

[0038] A synchronization member 6 is provided at one end of the sheath tube 2 close to the operating system 1 and is used to drive the multiple connecting plates 4 to move synchronously, thereby driving the multiple connecting plates 4 to be synchronously inserted into the corresponding connecting grooves 5;

[0039] A plurality of spray heads 7 are provided, and the plurality of spray heads 7 are all provided at one end of the sheath tube 2 away from the operating system 1, for spraying lidocaine. A storage plate 8 for storing lidocaine is provided in the sheath tube 2;

[0040] The extrusion plate 9 is slidably disposed in the storage plate 8. The extrusion plate 9 slides in the storage plate 8 to drive the lidocaine in the storage plate 8 to be discharged through the multiple spray heads 7.

[0041] The driving member 10 is disposed in the sheath tube 2 and the operating system 1 . The driving member 10 drives the squeezing plate 9 to move, causing it to slide in the storage plate 8 , thereby causing the lidocaine in the storage plate 8 to be sprayed out through the spray head 7 .

[0042] The sealing groove 12 is provided on the outer side of the sealing ring 11, and the rubber ring 13 is provided on the outer side of the sealing ring 11, and the bottom of the rubber ring 13 is in contact with the end of the sheath tube 2 near the operating system 1. When the sheath tube 2 is aligned with the operating system 1, the sealing groove 12 provided at the bottom of the operating system 1 will first fit tightly with the sealing ring 11 at the top of the sheath tube 2 to form a sealing ring 11 environment, preventing air leakage at the connection between the sheath tube 2 and the operating system 1, ensuring good airtightness during operation, and preventing external gas from entering and affecting the inspection results. When the sealing groove 12 in the operating system 1 is sleeved on the outer side of the sealing ring 11, the rubber ring 13 provided on the outer side of the sealing ring 11 will be further compressed after being squeezed by the bottom end of the operating system 1, thereby enhancing the sealing effect and ensuring stable airtightness during operation. Its function is that, through the cooperation of the sealing groove 12, the sealing plate 11 and the rubber ring 13, the connection between the operating system 1 and the sheath tube 2 is more firm, effectively preventing gas or liquid leakage, ensuring the accuracy and safety of the inspection, and improving the efficiency of diagnosis and treatment.

[0043] The synchronizer 6 includes a synchronizer plate 61 arranged on one side of the plurality of connecting plates 4, and a synchronizer ring 62 is arranged on the outer side of the plurality of synchronizer plates 61. One end of the plurality of connecting plates 4 close to the synchronizer plate 61 is provided with a return spring 63, the other end of which is arranged in the sheath tube 2. When the staff rotates the synchronizer ring 62, the synchronizer ring 62 will drive the plurality of synchronizer plates 61 to move simultaneously, and the plurality of synchronizer plates 61 will drive the corresponding connecting plates 4, so that the connecting plates 4 are retracted into the sheath tube 2, and at the same time the return spring 63 is compressed. Then, the end of the sheath tube 2 with the connecting plate 4 is inserted into the bottom end of the operating system 1, and the plurality of connecting plates 4 are aligned with the corresponding connecting grooves 5, and then the synchronizer ring 62 is loosened. When the synchronizer ring 62 is loosened, the return spring 63 is released, and the connecting plate 4 will automatically pop out and tightly embed into the connecting groove 5 under the action of the return spring 63, ensuring that the sheath tube 2 is firmly connected to the operating system 1. It is characterized in that the synchronizer plate 61 and the connecting plate 4 are driven to move synchronously by the synchronizer ring 62, so as to achieve fast and accurate assembly and disassembly, improve operational efficiency, and ensure the consistency and safety of the medical process.

[0044] A first drug inlet tube 14 for use with the storage plate 8 is provided in the sheath 2, and the first drug inlet tube 14 is communicated with the storage plate 8. A second drug inlet tube 15 for use with the first drug inlet tube 14 is provided in the operating system 1, and the first drug inlet tube 14 is slidably provided in the second drug inlet tube 15 at one end close to the operating system 1. When the medical staff completes the connection and needs to use the sheath 2 and the operating system 1 to spray lidocaine into the patient's body, it is necessary to first inject lidocaine into the second drug inlet tube 15. The lidocaine entering the second drug inlet tube 15 will flow along the second drug inlet tube 15 to the first drug inlet tube 14, and enter the storage plate 8 along the first drug inlet tube 14. Its function is to ensure that lidocaine evenly covers the target area by precisely controlling the flow and distribution of the drug, effectively reducing the patient's pain, improving the comfort of treatment, and at the same time avoiding drug waste and ensuring drug safety.

[0045] The driving member 10 includes a first driving rope 101 arranged on the side of the extrusion plate 9 away from the multiple spray heads 7, two second driving ropes 102 are arranged on the outside of the first driving rope 101, and the two second driving ropes 102 and the first driving rope 101 are arranged in a ring-shaped and equidistant manner on the extrusion plate 9, and an arc-shaped buckle 103 used in conjunction with the two second driving ropes 102 is provided in the storage plate 8. The end of the first driving rope 101 away from the extrusion plate 9 passes through the first drug inlet tube 14 and extends to the end of the second drug inlet tube 15 away from the sheath tube 2. When the medical staff needs to spray, they need to pull the first driving rope 101 exposed at one end of the second drug inlet tube 15, so that the first driving rope 101 drives the extrusion plate 9 to slide in the storage plate 8. When the first driving rope 101 is pulled, the first driving rope 101 will drive the two The second driving ropes 102 move together. Since the two second driving ropes 102 are restricted by the corresponding arc-shaped buckles 103, the two second driving ropes 102 drive the extrusion plate 9 to move toward the operating system 1 under the action of the arc-shaped buckles 103. The two second driving ropes 102 and the first driving rope 101 are equidistant and arranged in a ring shape, which can form a triangular structure with the connection points of the first driving rope 101 and the two second driving ropes 102 and the extrusion plate 9, ensuring that the extrusion plate 9 is evenly stressed, and then in the process of the extrusion plate 9 sliding in the storage plate 8, it is more stable, avoiding the extrusion plate 9 from tilting or offsetting. Its function is to stabilize the extrusion plate 9 through the triangular structure, ensure the uniform spraying of the medicine, improve the spray effect, reduce operating errors, ensure the accuracy of treatment, and further optimize the medical operation process.

[0046] An extrusion spring 16 is provided on the side of the extrusion plate 9 away from the multiple spray heads 7, and the other end of the extrusion spring 16 is provided on the inner wall of the storage plate 8. When the medical staff pulls the first drive rope 101, under the coordinated action of the two second drive ropes 102, the extrusion plate 9 moves stably toward the operating system 1. At this time, the extrusion spring 16 provided between the extrusion plate 9 and the storage plate 8 begins to compress and accumulate force. Its function is to ensure that the extrusion plate 9 can be quickly reset during the rebound process through the accumulation and release of the extrusion spring 16, maintain the continuity and stability of drug delivery, further optimize the smoothness of the spray operation, improve the treatment effect, reduce patient discomfort, and ensure the accuracy and efficiency of medical operations.

[0047] A spray tube 17 is provided between the multiple spray heads 7 and the storage plate 8. A one-way valve 28 is provided in each of the multiple spray tubes 17. A spray groove 18 is provided in each of the multiple spray tubes 17, and the multiple spray grooves 18 are all spiral-shaped. As the extrusion plate 9 slowly returns to its original position, the multiple one-way valves 28 open, and the lidocaine in the storage plate 8 enters the spray tube 17 through the one-way valve 28. The lidocaine in the spray tube 17 enters the spray groove 18 after passing through the one-way valve 28, and is finally evenly sprayed out through the spray head 7, thereby ensuring the continuity and stability of the anesthetic effect, while avoiding drug waste and improving operational efficiency and safety. The spiral spray groove 18 design can not only increase the flow speed of the drug solution in the spray groove 18, but also increase the pressure of the drug solution in the process of flowing in the spiral spray groove 18, thereby compensating for the pressure loss caused by the length of the spray tube 17, ensuring that the drug solution pressure at the spray head 7 is sufficient, further optimizing the spray effect, improving the penetration and coverage of anesthetic drugs, and meeting the precise needs of clinical operations. Its function is to significantly improve the anesthesia effect, reduce patient pain, ensure the smooth progress of the operation, and reduce medical costs by optimizing the drug delivery path and spray mechanism.

[0048] A plurality of medicine discharge grooves 19 are provided on the extrusion plate 9, and a plurality of medicine discharge plates 20 are provided on the extrusion plate 9 by rotating the rotating shaft, and the plurality of medicine discharge plates 20 correspond one-to-one to the plurality of medicine discharge grooves 19. A plurality of one-way grooves 21 are provided on one side of the extrusion plate 9 close to the plurality of spray heads 7, and the plurality of one-way grooves 21 correspond one-to-one to the plurality of medicine discharge plates 20 and are used in conjunction with each other. When the extrusion plate 9 is pulled by the first driving rope 101 and the second driving rope 102, the one-way valve 28 is provided in the spray tube 17, so that the extrusion plate 9 cannot inhale air through the one-way valve 28, thereby forming a negative pressure between the extrusion plate 9 and the plurality of one-way valves 28. At this time, under the action of the negative pressure, the multiple medicine discharge plates 20 provided on the extrusion plate 9 are slowly rotated by rotating the rotating shaft. The drug discharge groove 19 is moved so as to slowly open, thereby gradually weakening the negative pressure between the extrusion plate 9 and the multiple one-way valves 28, and the lidocaine will enter between the extrusion plate 9 and the multiple spray tubes 17 through the multiple drug discharge grooves 19. The multiple one-way grooves 21 provided on the extrusion plate 9 can prevent the drug discharge plate 20 from rotating toward the side of the operating system 1, so that the rotation direction of the drug discharge plate 20 is restricted. Its function is to control the rotation direction of the drug discharge plate 20 through the one-way grooves 21 to ensure that the drug accurately enters between the spray tube 17 and the extrusion plate 9, thereby realizing the directionality and controllability of drug delivery, improving the uniformity of the spray, ensuring the accuracy of the amount of spray each time, reducing drug waste, ensuring the maximization of the treatment effect, and further optimizing the safety and reliability of medical operations.

[0049] A plurality of limiting plates 22 are provided on one side of the extrusion plate 9 close to the plurality of spray heads 7, and the plurality of limiting plates 22 correspond one to one with the plurality of medicine discharge plates 20. When the medicine discharge plate 20 rotates, the plurality of limiting plates 22 provided on the extrusion plate 9 will limit the rotation angle of the medicine discharge plate 20, so that the plurality of medicine discharge plates 20 can expose the medicine discharge groove 19 without rotating too much, resulting in the medicine discharge plate 20 being unable to reset after rotating a large angle. Its function is to ensure that the medicine discharge plate 20 rotates within a reasonable range through precise control of the limiting plate 22, which not only ensures the smooth delivery of the drug, but also prevents the medicine discharge plate 20 from rotating too much and affecting the reset, further ensuring the stability and accuracy of the drug delivery, improving the reliability of the spray operation, reducing operational errors, ensuring the safety and comfort of the patient during use, maximizing the treatment effect, and optimizing the overall medical operation experience.

[0050] A micro camera 23 is provided at the end of the sheath 2 away from the operating system 1, and a data transmission line 24 is provided at one end of the micro camera 23. The data transmission line 24 passes through the sheath 2 and extends to the bottom of the operating system 1. A data plug 25 is provided at the end of the data transmission line 24 away from the micro camera 23, and a data slot 26 is provided at the bottom of the operating system 1 for use with the data plug 25. When the sealing ring 11 is docked with the sealing groove 12, medical staff need to pay attention to inserting the data plug 25 at one end of the data transmission line 24 in the sheath 2 into the data slot 26 at the bottom of the operating system 1 to ensure smooth data transmission so that the image captured by the micro camera 23 can be transmitted to the operating system 1 in real time for accurate observation by medical staff. Its function is to accurately insert the data plug 25 at one end of the data transmission line 24 into the data slot 26 when connecting the sheath 2 and the operating system 1 to ensure unimpeded image transmission from the micro camera 23 and improve the accuracy and safety of surgical operations.

[0051] During use, when medical staff need to use a disposable electronic soft bronchoscope, they first take out the operating system 1 and the sheath tube 2, and then align the sheath tube 2 with the bottom end of the operating system 1, and rotate the synchronization ring 62. When the staff rotates the synchronization ring 62, the synchronization ring 62 will drive multiple synchronization plates 61 to move at the same time, and multiple synchronization plates 61 will drive the corresponding connecting plates 4, so that the connecting plates 4 are retracted into the sheath tube 2, and at the same time the reset spring 63 is compressed, and then the end of the sheath tube 2 with the connecting plate 4 is inserted into the bottom end of the operating system 1, and the multiple connecting plates 4 are aligned with the corresponding connecting grooves 5, and then the synchronization ring 62 is loosened. When the synchronization ring 62 is loosened, the reset spring 63 is released, and the connecting plate 4 will automatically pop out under the action of the reset spring 63 and tightly embed into the connecting groove 5, ensuring that the sheath tube 2 is firmly connected to the operating system 1. When the sheath tube 2 is aligned with the operating system 1, , the sealing groove 12 opened at the bottom of the operating system 1 will first fit tightly with the sealing ring 11 at the top of the sheath tube 2, forming a sealing ring 11 environment to prevent air leakage at the connection between the sheath tube 2 and the operating system 1, ensuring good airtightness during operation, and preventing external gas from entering and affecting the inspection results. When the sealing groove 12 in the operating system 1 is sleeved on the outside of the sealing ring 11, the rubber ring 13 arranged on the outside of the sealing ring 11 will be further compressed after being squeezed by the bottom of the operating system 1, thereby enhancing the sealing effect and ensuring stable airtightness during operation. When the sealing ring 11 is docked with the sealing groove 12, medical staff need to pay attention to inserting the data plug 25 at one end of the data transmission line 24 in the sheath tube 2 into the data slot 26 at the bottom of the operating system 1 to ensure smooth data transmission so that the images captured by the micro camera 23 are transmitted to the operating system 1 in real time for accurate observation by medical staff;

[0052] Before the sheath tube 2 is connected to the operating system 1, the steering system 27 needs to be connected to the operating system 1 through the sheath hole 3. This is a prior art and will not be described in detail here. Before the sheath tube 2 is connected to the operating system 1, the medical staff needs to first insert the end of the first driving rope 101 away from the extrusion plate 9 into the operating system 1 through the second drug inlet tube 15, and then pass it out through the end of the second drug inlet tube 15 away from the first drug inlet tube 14, thereby completing the connection between the sheath tube 2 and the operating system 1 and ensuring that the driving rope is accurately positioned, thereby making subsequent operations more convenient.

[0053] After the medical staff completes the above-mentioned connection steps and needs to use the sheath tube 2 and the operating system 1 to spray lidocaine into the patient's body, it is necessary to first inject lidocaine into the second drug inlet tube 15. The lidocaine entering the second drug inlet tube 15 will flow along the second drug inlet tube 15 to the first drug inlet tube 14 and enter the storage plate 8 along the first drug inlet tube 14. At this time, the lidocaine entering the storage plate 8 will be on the side of the squeezing plate 9 away from the spray head 7. When the medical staff needs to spray, it is necessary to pull the first driving rope 101 exposed at one end of the second drug inlet tube 15, so that the first driving rope 101 drives the squeezing plate 9 to slide in the storage plate 8. When the first driving rope 101 is pulled, the first driving rope 101 is pulled. The moving rope 101 drives the two second driving ropes 102 to move together. Since the two second driving ropes 102 are restricted by the corresponding arc-shaped buckles 103, the two second driving ropes 102 drive the extrusion plate 9 to move toward the operating system 1 under the action of the arc-shaped buckles 103. The two second driving ropes 102 and the first driving rope 101 are equidistant and arranged in a ring shape, so that the connection points of the first driving rope 101 and the two second driving ropes 102 with the extrusion plate 9 form a triangular structure, ensuring that the extrusion plate 9 is evenly stressed. As a result, the extrusion plate 9 slides more smoothly in the storage plate 8, avoiding tilting or deviation of the extrusion plate 9, thereby ensuring uniform spraying of lidocaine and achieving an ideal anesthetic effect.

[0054] When the medical staff pulls the first driving rope 101, under the coordinated action of the two second driving ropes 102, the extrusion plate 9 moves stably toward the operating system 1. At this time, the extrusion spring 16 arranged between the extrusion plate 9 and the storage plate 8 begins to compress and accumulate force. When the extrusion plate 9 is pulled by the first driving rope 101 and the second driving rope 102, the one-way valve 28 is provided in the spray tube 17, so that the extrusion plate 9 cannot inhale air through the one-way valve 28, thereby forming a negative pressure between the extrusion plate 9 and the multiple one-way valves 28. At this time, under the action of the negative pressure, the extrusion plate 9 rotates the multiple medicine discharge plates 20 arranged on the extrusion plate 9 through the rotating shaft, and the medicine discharge slot 19 slowly rotates, so that the medicine discharge slot 19 slowly opens. As a result, the negative pressure between the extrusion plate 9 and the multiple one-way valves 28 is gradually weakened, and the lidocaine enters between the extrusion plate 9 and the multiple spray pipes 17 through the multiple drug discharge grooves 19. The multiple one-way grooves 21 provided on the extrusion plate 9 can prevent the drug discharge plate 20 from rotating toward the side of the operating system 1, so that the rotation direction of the drug discharge plate 20 is restricted, ensuring that the lidocaine can only flow in one direction, and finally be evenly sprayed through the spray head 7 to achieve the purpose of precise anesthesia. When the drug discharge plate 20 rotates, the multiple limit plates 22 provided on the extrusion plate 9 will limit the rotation angle of the drug discharge plate 20, so that the multiple drug discharge plates 20 can expose the drug discharge grooves 19 without rotating too much, resulting in the drug discharge plate 2 0 cannot be reset after being rotated to a large angle. When the squeezing plate 9 is pulled to the limit position by the first driving rope 101 and the second driving rope 102, the medical staff can loosen the first driving rope 101. At this time, the squeezing spring 16 quickly releases the stored force to push the squeezing plate 9 to reset. When the squeezing plate 9 is squeezed and reset by the squeezing spring 16, the squeezing plate 9 will move toward the multiple spray tubes 17. In the process of the squeezing plate 9 sliding toward the multiple spray tubes 17, the multiple drug discharge plates 20 will be impacted by the water flow and the combined effect of the limit plate 22, gradually reset, so that the drug discharge groove 19 is closed to prevent the lidocaine from flowing back. As the squeezing plate 9 slowly resets, the multiple one-way valves 28 open, and the lidocaine in the storage plate 8 is discharged. The lidocaine will pass through the one-way valve 28 and enter the spray tube 17. The lidocaine entering the spray tube 17 will enter the spray tank 18 after passing through the one-way valve 28, and will finally be evenly sprayed out through the spray head 7, ensuring the continuity and stability of the anesthetic effect, while avoiding drug waste and improving operational efficiency and safety. The spiral spray tank 18 design can not only increase the flow speed of the drug solution in the spray tank 18, but also increase the pressure of the drug solution during the flow in the spiral spray tank 18, thereby compensating for the pressure loss caused by the length of the spray tube 17, ensuring that the drug pressure at the spray head 7 is sufficient, further optimizing the spray effect, improving the penetration and coverage of anesthetic drugs, and meeting the precise needs of clinical operations.
