Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a replaceable, disposable bronchoscope. Background Technology

[0002] Bronchoscopes are important medical devices used to examine and treat respiratory diseases. Currently, most hospitals still use traditional bronchoscopes, which are expensive to purchase and pose a risk of cross-infection during use. Therefore, more and more hospitals are now using disposable bronchoscopes to replace traditional bronchoscopes.

[0003] Disposable bronchoscopes are generally one-piece units that are used and then discarded, which can effectively prevent cross-infection. Although they are convenient to use, discarding the entire bronchoscope greatly increases the cost of use. In actual use, the infection mainly occurs through the intubation tube that is inserted into the patient's body, and has nothing to do with the external operating end.

[0004] Therefore, it is necessary to provide a replaceable, split-type disposable bronchoscope to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: including an operating handle, an intubation tube, and a connecting assembly connecting the two;

[0006] The connecting assembly includes a tube body, a wire rope connector, and a snap fastener. The snap fasteners are arranged in a circular pattern at the input end of the tube body, and the output end of the tube body is provided with the same snap fasteners. These snap fasteners can securely snap the operating handle to the inlet tube. The tube body is slidably provided with symmetrical wire rope connectors on both sides, which pass through the tube body and connect the operating handle and the wire rope in the inlet tube together.

[0007] A connecting platform one is slidably disposed on the left side of the tube body, and a connecting platform two is slidably disposed on the right side of the tube body. A return spring is also disposed between the connecting platform one and the connecting platform two and the tube body. Under the action of the return spring, the operating handle and the insertion tube can be pushed tightly onto the snap-fit ​​component.

[0031] Example: Please refer to Figures 1-8 In this embodiment of the invention, it includes an operating handle 1, an inlet tube 2, and a connecting component 3 that connects the two.

[0032] The connecting assembly 3 includes a tube body 31, a wire rope connector 34, and a snap fastener 35. The snap fastener 35 is arranged in a circular pattern at the input end of the tube body 1, and the output end of the tube body 1 is provided with the same snap fastener 35, which can securely snap the operating handle 1 to the inlet tube 2. The tube body 1 is slidably provided with symmetrical wire rope connectors 34 on both sides, which pass through the tube body 31 to connect the operating handle 1 and the wire rope 6 in the inlet tube 2 together.

[0033] A connecting platform 32 is slidably disposed on the left side of the tube body 31, and a connecting platform 33 is slidably disposed on the right side of the tube body 31. A return spring is also disposed between the connecting platform 32 and the connecting platform 33 and the tube body 31. Under the action of the return spring, the operating handle 1 and the inlet tube 2 can be pushed tightly onto the snap-fit ​​member 35.

[0034] In practice, the operating handle 1 and the wire rope 6 in the intubation tube 2 are connected by the wire rope connector 34. The connecting end of the operating handle 1 can press the connecting platform 32 inward, and then be locked in the connecting assembly 3 by the snap-fit ​​35 on the connecting assembly 3. At this time, the connecting platform 32 pushes the operating handle 1 to slide under the action of the spring, so that the operating handle 1 and the snap-fit ​​part on the connecting assembly 3 fit together tightly. Similarly, the intubation tube 2 can press the connecting platform 33 and cooperate with the snap-fit ​​35 to make the intubation tube 2 fit together tightly with the snap-fit ​​part on the connecting assembly 3. After the connection is completed, the operating handle 1, the connecting assembly 3 and the intubation tube 2 will form a complete bronchoscope.

[0035] In this embodiment, as Figure 1 ,2 It also includes an elastic tube 4 and a CCD transmission line 5. The elastic tube 4 is fixedly installed at the output end of the intubation tube 2. The elastic tube 4 is controlled to deflect by a steel wire rope 6 installed in the intubation tube 2 and the operating handle 1. The front end of the elastic tube 4 is also equipped with an integrated LED light and a camera device. The CCD transmission line 5 is used to transmit the camera image. It can be connected to a display screen to observe the patient's internal condition.

[0036] It should be noted that the LED integrated light can be directly installed on the elastic tube 4 without external wiring, and it can work continuously for 4 hours. The rest are all existing technologies and will not be described in detail here.

[0037] In this embodiment, as Figure 3 The snap-fit ​​component 35 includes a snap hook 351 and a rotating ring 352. The snap hook 351 is circumferentially distributed and rotatably disposed on the tube body 31. A spring is disposed between the snap hook 351 and the tube body 31. The rotating ring 352 is rotatably disposed on the tube body 31.

[0038] The hook 351 is also provided with a sliding groove 353;

[0039] The rotating ring 352 has multiple arc-shaped sliders distributed in a circle. The sliders can slide into the groove 353 during the rotation of the rotating ring 352 and squeeze the hook 351 to cause it to deflect.

[0040] In this embodiment, as Figure 3 , 4 The operating handle 1 is fixedly provided with a second hook 11 that cooperates with the snap-fit ​​part 35 at the connection point between it and the connecting component 3. The inlet tube 2 is fixedly provided with a third hook 21 that cooperates with the snap-fit ​​part 35 at the connection point between it and the connecting component 3. Both the second hook 11 and the third hook 21 can be snapped into the first hook 351 so that the operating handle 1 and the inlet tube 2 are snapped onto the connecting component 3.

[0041] In this embodiment, as Figure 3 , 4 The first hook 351 includes a rod 3511 and a hook 3512. The hook 3512 is C-shaped, with an arc-shaped end away from the rod 3511 and a groove at the end near the rod 3511. The second hook 11 and the third hook 21 are both provided with protrusions, which can be inserted into the groove to fix the locking position.

[0042] During implementation, hook 2 11 can squeeze hook 1 351 located at the input end of the connecting component 3 to cause it to deflect. After hook 2 11 passes the hook body part at the front end of hook 1 351, hook 1 351 is engaged in hook 2 11 under the action of the spring, and its position is fixed by the action of the protrusion and the groove. Similarly, hook 3 21 can also be engaged in hook 1 351 located at the output end of the connecting component 3. After use, push the inlet tube 2 into the connecting component to separate the protrusion and the groove. Then rotate the rotating ring 352 to make the slider slide into the slide groove 353 and squeeze hook 1 351 to cause it to deflect and get out of the engagement range of hook 3 21. Then remove the inlet tube 2 and the steel wire rope and CCD transmission line together. Then connect a new inlet tube 2 for the next use. Similarly, a new operating handle 1 or connecting component 3 can also be replaced.

[0043] In this embodiment, as Figure 5 The tube body 31 has a through hole 311, which can connect the operating handle 1 and the working channel 7 in the inlet tube 2. The tube body 31 is also provided with a transmission line buckle 312, which can connect the operating handle 1 and the CCD transmission line 5 in the inlet tube 2.

[0044] It should be noted that the buckle 312 is a general wire buckle, which is existing technology, and the size of the through hole 311 is the same as the size of the working channel 7.

[0045] In this embodiment, as Figure 6 , 7 The steel wire rope 6 in the operating handle 1 is provided with a pull ring 61, and the steel wire rope 6 in the inlet tube 2 is provided with a pull ring 62.

[0046] The wire rope connector 34 includes a slide bar 341, a first locking block 342, and a second locking block 343. The slide bar 341 has two notches at both ends. The first locking block 342 and the second locking block 343 are respectively rotatably disposed in the two notches. A locking slot 3411 is provided on the upper side of the notch, and a locking groove 3412 is also provided on the notch.

[0047] The first card block 342 is provided with a second card slot 3421, and a first stop bar 3422 is provided on both sides of it. The first stop bar 3422 can be inserted into the slot 3411 located at the input end of the connecting component 3.

[0048] The second card block 343 has a slot 3431, and two stops 3432 are provided on both sides of it. The stops 3432 can be inserted into the slot 3411 located at the output end of the connecting component 3.

[0049] In implementation, such as Figure 8 As shown, the pull ring 61 is pushed into the slot 3421, causing the locking block 342 to rotate. During rotation, the pull ring 61 slides into the slot 3412. When the pull ring 61 reaches the bottom of the slot 3412, the stop lever 3422 engages with the slot 3411. At this time, the slot 3421 and the slot 3412 form a closed locking ring, connecting the steel wire rope 6 in the operating handle 1 to the steel wire rope. The 34 pieces are connected together. Similarly, the second pull ring 62 and the second locking block 343 cooperate to lock into the first locking groove 3412 at the other end, connecting the steel wire rope 6 in the body tube 2 with the steel wire rope connector 34, finally forming a complete steel wire rope. After use, simply remove the first stop bar 3422 and the second stop bar 3432 from the locking slot 3411 to separate the first pull ring 61 and the second pull ring 62 from the steel wire rope connector 34.

[0050] In this embodiment, the diameter of the slide bar 341 is larger than the maximum diameter of the pull ring 61 and the pull ring 62.

[0051] Specifically, by setting the diameter of the slide bar 341 to be larger than the maximum diameter of the pull ring 61 and the pull ring 62, it can effectively prevent the pull ring 61 or the pull ring 62 from getting stuck in the wire rope connector during the adjustment of the direction of the elastic tube 4.

[0052] In summary, when implementing this device, the steel wire rope 6 and the CCD transmission line located in the operating handle 1 and the inlet tube 2 are first connected through the steel wire rope connector 34 and the buckle 312 in the connecting assembly 3. Then, the operating handle 1 and the inlet tube 2 are pushed into the two ends of the connecting assembly 3 respectively. Under the action of the first hook 351, the second hook 11 and the third hook 21, the three are firmly connected. After use, the inlet tube 2 is pushed into the connecting assembly 3 again and the rotating ring 352 is rotated so that the first hook 351 and the third hook 21 are separated. Then, a new inlet tube 2 is replaced and the device is used again.
