Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a rigid electronic respiratory endoscope system. Background Technology

[0002] A rigid bronchoscope, also known as a rigid bronchoscope, is a basic tool for interventional respiratory diagnosis and treatment. Most basic interventional respiratory procedures can be performed through a rigid bronchoscope. The use of this device greatly improves the convenience and safety of interventional respiratory diagnosis and treatment.

[0003] An existing patent (publication number: CN110960183B) discloses a bronchoscope stent, which uses a stent assembly to assist in the insertion of the wire into the bronchoscope body, thereby effectively avoiding the problem of inaccurate positioning caused by manual operation by medical personnel. At the same time, the lubricating component in the stent assembly applies lubricant to the outside of the wire, making the insertion smoother.

[0004] However, the above-mentioned technical solutions still have certain drawbacks. The lead wire of the bronchoscope body is introduced through the lead wire roller, and then the lead wire is lubricated with lubricant using a hollow lubricating sleeve. However, after the medical staff finishes examining the patient and removes the lead wire, the outer wall of the lead wire will carry out the patient's saliva, sputum and other mucus along with it. At this time, these saliva, sputum and other mucus will pass through the hollow lubricating sleeve and lead wire roller again, which causes these mucus to adhere to the lubricating sleeve and lead wire roller. After the device is used and before the next use, medical staff need to replace the lubricating sleeve and perform deep cleaning and disinfection of the lead wire roller. This not only increases medical costs but also prolongs the disinfection and cleaning time of the device. Therefore, a rigid electronic bronchoscope system is proposed. Summary of the Invention

[0016] In summary, the present invention has the following main beneficial effects:

[0017] 1. This invention uses a guide mechanism to assist in the insertion of the wire, making the insertion into the patient's nasal cavity or oral cavity more stable and avoiding inaccurate positioning caused by the tremors of medical staff. After the device is used up, before pulling out the wire, the second handle can be rotated in the opposite direction to separate the two wire rollers, thereby preventing the mucus adhering to the outer wall of the wire from contacting and adhering to the two wire rollers when the wire is pulled out, thus increasing the workload of subsequent cleaning by the staff.

[0018] 2. This invention designs an applicator to apply lubricant to the outside of the wire, making wire insertion smoother. When the wire is removed, the two hollow lubricating sleeves separate along with the two sets of U-shaped mounting plates, which also prevents the adhesive fluid adhering to the outer wall of the wire from coming into contact with the applicator sponge. Once the applicator sponge comes into contact with the outer wall of the wire, it needs to be replaced, which would increase medical costs and the workload of staff. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of the present invention will now be described.

[0036] Rigid electronic ventilator system, such as Figure 1-9As shown, the bronchoscope includes a bronchoscope body 100, which includes an operating part 110. A guide wire 120 is installed at one end of the operating part 110. A snap-fit ​​assembly 200 is installed on the outer wall of the operating part 110. An adjustment assembly 300 is fixedly connected to one side of the operating part 110 via the snap-fit ​​assembly 200. A guide mechanism 400 is provided on one side of the adjustment assembly 300, and an application assembly 500 is connected below the guide mechanism 400. The guide mechanism 400 includes an L-shaped connecting rod 410, with L-shaped fixing plates 420 fixedly connected to both sides of one end of the L-shaped connecting rod 410. Two sets of L-shaped fixing plates 420... A bidirectional threaded screw 430 is provided laterally on one side between the two sets of U-shaped mounting plates 440. Both sides of the outer wall of the bidirectional threaded screw 430 are threadedly connected to U-shaped mounting plates 440. A rotating shaft 451 connected by bearings is provided in each of the two sets of U-shaped mounting plates 440. A guide roller 450 is fixedly sleeved on the outer wall of the rotating shaft 451. A guide rod 460 is provided laterally on the side of the two sets of L-shaped fixing plates 420 away from the bidirectional threaded screw 430. The two sets of U-shaped mounting plates 440 are slidably connected to the guide rod 460. One end of the bidirectional threaded screw 430 extends through to the outside of a set of L-shaped fixing plates 420 and is fixedly connected to a second rotating handle 470.

[0037] Before using the bronchoscope body 100, medical staff rotate the second handle 470 to drive the bidirectional threaded screw 430 to rotate, thereby causing the two sets of U-shaped mounting plates 440 connected to it to move relative to each other. This, in turn, causes the rotating shaft 451 and guide roller 450 installed in the two sets of U-shaped mounting plates 440 to move synchronously relative to each other until they reach the appropriate position. After moving to the appropriate position, the medical staff inserts the guide 120 between the two guide rollers 450. The friction between the guide 120 and the guide roller 450 causes the two guide rollers 450 to rotate synchronously in opposite directions, thereby enabling the swallowing of the guide 120. This assists in the introduction of the guide 120, making the insertion into the patient's nasal cavity or oral cavity more stable and avoiding inaccurate positioning caused by the medical staff's hand tremors. After the device is used, before withdrawing the guide 120, the second handle 470 can be rotated in the opposite direction to drive the two guide rollers 450 to separate. This prevents the mucus adhering to the outer wall of the guide 120 from contacting and adhering to the two guide rollers 450 when it is withdrawn, thus avoiding increasing the workload of the staff in subsequent cleaning.

[0038] Please refer to this carefully. Figure 1 , Figure 6 , Figure 8 as well as Figure 9As shown, the coating assembly 500 includes a fixing bracket 510 fixedly installed on the outside of each U-shaped mounting plate 440. A semi-circular connecting ring 520 is fixedly installed at the other end of each fixing bracket 510. A half-section of a hollow lubrication sleeve 530 is fixedly connected to the inner side of each of the two semi-circular connecting rings 520. Each half-section of the hollow lubrication sleeve 530 has a liquid storage chamber 540 inside its bottom end. An L-shaped connecting rod 410 is fixedly mounted near the bottom of the L-shaped fixing plate 420 via a connecting seat. A piston cylinder 570 is provided, and a piston rod 580 passes through the piston cylinder 570. A piston 590 is fixedly installed at one end of the piston rod 580 located inside the piston cylinder 570. A first connecting pipe 5910 is fixedly connected to one side of the bottom end of the piston cylinder 570, and a liquid storage tank 5920 is fixedly installed at the other end of the first connecting pipe 5910. The liquid storage tank 5920 is fixedly installed on the top of the L-shaped connecting rod 410 near the L-shaped fixing plate 420. The other side of the bottom end of the piston cylinder 570 is fixedly connected to... A second connecting pipe 5930 is connected, and two branch pipes 5940 are fixedly connected to the other end of the second connecting pipe 5930. The other ends of the two branch pipes 5940 extend into the corresponding liquid storage chambers 540. A connecting plate 5950 is fixedly installed on the end of the piston rod 580 away from the piston 590. The other end of the connecting plate 5950 is fixedly connected to the outer wall of the hollow lubrication sleeve 530. Both the first connecting pipe 5910 and the second connecting pipe 5930 have internal installations. It has a one-way valve, and the two branch pipes 5940 are set as bellows. When the two halves of the hollow lubrication sleeve 530 are combined, they form a complete hollow lubrication sleeve 530. The complete hollow lubrication sleeve 530 is set in a trumpet shape that is wider at the top and narrower at the bottom. Each half of the hollow lubrication sleeve 530 has an oil outlet hole 550 that communicates with the liquid storage chamber 540 on the inner side of the lower end. A semi-circular applicator sponge 560 is fixedly installed on the inner side of the lower end of each half of the hollow lubrication sleeve 530.

[0039] As the two sets of U-shaped mounting plates 440 approach each other, they respectively drive the corresponding fixed brackets 510 and semi-circular connecting rings 520 to move relative to each other. This causes the two halves of the hollow lubrication sleeve 530 to merge into a complete hollow lubrication sleeve 530. The complete hollow lubrication sleeve 530 is designed in a trumpet shape, wider at the top and narrower at the bottom, to facilitate the subsequent wire 120 passing through the guide mechanism 400 and the hollow lubrication sleeve 530. At the same time, when one half of the hollow lubrication sleeve 530 moves closer to the center, the piston rod 580, which is fixedly connected by the connecting plate 5950, drives the piston 590 to move towards the bottom of the inner cavity of the piston cylinder 570. This forces the lubricating oil extracted in the previous action into the second connecting pipe 5930, and finally into the second connecting pipe 5930 through the two branch pipes 5940. In the reservoir chamber 540 within the two hollow lubrication sleeves 530, lubricating oil is continuously replenished to the sizing sponge 560 via the oil outlet 550. This ensures that the lubricating oil on the sizing sponge 560 continuously coats the outer wall of the lead wire 120 during insertion. The sizing assembly 500 applies lubricant to the outer side of the lead wire 120, making insertion smoother. Simultaneously, when the lead wire 120 is removed, the two hollow lubrication sleeves 530 separate along with the two sets of U-shaped mounting plates 440, preventing the adhesive residue from the outer wall of the lead wire 120 from contacting the sizing sponge 560. If the sizing sponge 560 comes into contact with the outer wall of the lead wire 120, it needs to be replaced, increasing medical costs and the workload of staff.

[0040] Please refer to this carefully. Figure 1-3 As shown, the snap-fit ​​assembly 200 includes a fixed frame 210 fixedly sleeved on the outer wall of the operating part 110. A connecting post 220 is fixedly connected to one side of the fixed frame 210, and a snap-fit ​​block 230 is fixedly installed at the other end of the connecting post 220. The snap-fit ​​block 230 is connected to a connecting block 240. A snap-fit ​​groove 250 matching the snap-fit ​​block 230 is opened on the side of the connecting block 240 near the snap-fit ​​block 230. Movable chambers are opened on both sides of the groove 250, and trapezoidal sliders 260 are slidably connected in both movable chambers. A first pull rod 270 is fixedly connected to the rear side of each trapezoidal slider 260. A first spring 290 is fixedly connected between the rear side of the trapezoidal slider 260 and one side of the movable chamber. The first spring 290 is sleeved on the outer wall of the first pull rod 270. The end of the first pull rod 270 away from the trapezoidal slider 260 extends through to the outside of the connecting block 240 and is fixedly connected to a first pull handle 280.

[0041] Medical staff hold the operating unit 110 and align the mounting block 230 with the slot 250 on one side of the connecting block 240, then insert it. During the insertion of the mounting block 230, the two trapezoidal sliders 260 inside the slot 250 are compressed and move into the movable chamber, thereby compressing the first spring 290. When the mounting block 230 is fully inserted into the bottom of the slot 250, the two trapezoidal sliders 260 lose the compressive force, and the elastic force of the first spring 290 pushes the trapezoidal sliders 260 to the back side of the mounting block 230, forming a fixed limit on the mounting block 230. At the same time, when the device... After use, the first pull rod 270 and trapezoidal slider 260 can be moved into the active chamber by pulling the first pull handle 280, so that the trapezoidal slider 260 is disengaged from the back of the locking block 230, releasing the locking block 230 and the operating part 110, and the bronchoscope body 100 can be removed for subsequent cleaning and disinfection. The design of the locking component 200 and the adjustment component 300 greatly facilitates the installation and fixation of the bronchoscope body 100, further alleviating the hand pain caused by medical staff holding the device for a long time when using the device, which may even affect the examination and viewing of patients.

[0042] Please refer to this carefully. Figure 1 , Figure 4 as well as Figure 5 As shown, the adjusting assembly 300 includes a telescopic sleeve 310 fixedly connected to one side of the connecting block 240. A telescopic rod 320 is slidably connected inside the telescopic sleeve 310. A limiting assembly 330 is provided at the top of the end of the telescopic sleeve 310 away from the connecting block 240. A fixing block 340 is fixedly connected to the end of the telescopic rod 320 away from the telescopic sleeve 310. An electric push rod 350 is installed at the bottom of the fixing block 340. A base 360 ​​is fixedly installed at the bottom of the electric push rod 350. The limiting assembly 330 includes several sets of equidistantly distributed limiting holes 331 formed on the upper surface of the telescopic rod 320. The telescopic sleeve 310 is located away from the connecting block 240. A through hole matching the limiting hole 331 is opened at the top of one end of the telescopic sleeve 310, and a fixed sleeve 332 is fixedly installed above the through hole at the top of the telescopic sleeve 310. A second pull rod 333 matching the through hole and the limiting hole 331 is longitudinally provided inside the fixed sleeve 332. A fixed ring 334 is fixedly sleeved on the outer wall of the second pull rod 333. A second spring 335 is fixedly connected between the upper surface of the fixed ring 334 and the top of the inner cavity of the fixed sleeve 332. The second spring 335 is sleeved on the outer wall of the second pull rod 333. The top of the second pull rod 333 extends through to the top of the fixed sleeve 332 and is fixedly installed with a second pull handle 336.

[0043] Using the electric push rod 350, medical staff can adjust the vertical height of the device according to actual needs. At the same time, pulling the second handle 336 causes the second pull rod 333 and the fixing ring 334 to compress the second spring 335, causing the second pull rod 333 to disengage from the limiting hole 331, thereby releasing the limitation on the telescopic rod 320. The horizontal position of the device can then be adjusted according to actual needs. After adjustment, the second pull rod 336 can be released, allowing the second pull rod 333 to re-insert into the limiting hole 331, thus locking the telescopic rod 320. By setting the adjustment component 300, medical staff can adjust the vertical and horizontal positions of the device according to different patients and actual usage needs, thereby improving the usability of the device.

[0044] Please refer to this carefully. Figure 4 As shown, a fixed clamping plate 370 is fixedly connected to the bottom of one side of the base 360. A threaded rod 380 is connected to the upper surface of the fixed clamping plate 370 via a bearing. A movable clamping plate 390 is threadedly connected to the outer wall of the threaded rod 380. A guide groove matching one end of the movable clamping plate 390 is opened on one side of the base 360. One end of the movable clamping plate 390 is slidably connected to the guide groove. A first rotating handle 3910 is fixedly installed on the top of the threaded rod 380.

[0045] By rotating the first handle 3910, the threaded rod 380 is driven to rotate, thereby causing the movable clamping plate 390 to move downward. Together with the fixed clamping plate 370, it completes the clamping and fixing of external objects, thereby freeing the hands of medical staff and preventing them from experiencing hand pain due to prolonged gripping of the device, which would affect the testing process.

[0046] In use, rotating the second handle 470 drives the bidirectional threaded screw 430 to rotate, thereby causing the two U-shaped mounting plates 440 connected to it to move relative to each other. This, in turn, causes the rotating shaft 451 and the guide roller 450 installed inside the two U-shaped mounting plates 440 to move synchronously relative to each other until they reach the appropriate position. Medical personnel then insert the guide wire 120 between the two guide rollers 450. The friction between the guide wire 120 and the guide roller 450 causes the two guide rollers 450 to rotate synchronously in opposite directions, thus achieving the desired movement of the guide wire 120. The swallowing of the device assists in the introduction of the lead 120, making its insertion into the patient's nasal cavity or oral cavity more stable and avoiding inaccurate positioning caused by tremors of medical staff. After the device is used, before withdrawing the lead 120, the second handle 470 can be rotated in the reverse direction, thereby driving the two lead rollers 450 to separate. This prevents the mucus adhering to the outer wall of the lead 120 from contacting and adhering to the two lead rollers 450 when it is withdrawn, thus avoiding increasing the workload of subsequent cleaning by the staff. All parts of the device not mentioned herein are the same as or can be implemented using existing technology.
