Description

Technical Field

[0001] This invention belongs to the field of bronchoscopy technology, specifically referring to an auxiliary positioning and guidance device for bronchoscopy. Background Technology

[0002] Bronchoscopy involves inserting a thin bronchoscope through the mouth or nose into the patient's lower respiratory tract, passing through the glottis into the trachea, bronchi, and further distally. This allows for direct observation of lesions in the trachea and bronchi, and the corresponding examinations and treatments based on the lesions. Broadly speaking, bronchoscopic biopsy includes lesion biopsy, bronchial mucosal biopsy, transbronchial lung biopsy, and transbronchial needle aspiration biopsy. Most lung and airway diseases, such as tumors, interstitial lung diseases, granulomatous diseases, and certain infectious diseases, require bronchoscopic biopsy for diagnosis, making it one of the most commonly used examination procedures.

[0003] During bronchoscopy, doctors need to manually pull the bronchoscope to insert it into the patient's nasal cavity. However, manual pulling can easily cause misalignment of the bronchial tubing, which can easily cause discomfort to the patient. Positioning the bronchial tubing is also difficult, making the procedure challenging. Furthermore, different patients have different body structures, and current technology cannot be adjusted according to the patient's actual situation, making it difficult to reduce pain and improve comfort for patients with different conditions. Therefore, there is a need to propose an auxiliary positioning and guidance device for bronchoscopy. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a bronchoscopy guidance scheme with motion adjustment components and power components, which effectively solves the problem that current bronchoscopy guidance schemes on the market cannot automatically control the adjustment and start / stop of the equipment.

[0005] The technical solution adopted by the present invention is as follows: A bronchoscopy auxiliary positioning and guidance device includes a support frame, a motion adjustment component, a lifting component, a power component, a cable retraction component, and a fixing component. The support frame is provided with two sets of grooves. The motion adjustment component is located on the lifting component. The lifting component is located on the support frame. The power component is located on the lifting component. The cable retraction component is located on the motion adjustment component. The fixing component is located on the support frame. The fixing component fixes the patient's bronchoscopy tubing. The lifting component can drive the motion adjustment component, the power component, and the cable retraction component to move up and down. The cable retraction component retracts the bronchoscopy tubing. The power component drives the motion adjustment component to move and adjust, thereby causing the cable retraction component to move.

[0006] Furthermore, the motion adjustment component includes a sliding rail, a longitudinal sliding block, limit bars, a fixed rail, and a control switch. The sliding rail is slidably mounted on the lifting component, the longitudinal sliding block is fixedly mounted on the bottom surface of the sliding rail, there are four sets of limit bars, one end of each set of limit bars is fixedly mounted on the lifting component, the fixed rail is fixedly mounted on the four sets of limit bars, and the bottom of the fixed rail has an opening. There are two sets of control switches, both sets of control switches are fixedly mounted on both ends of the fixed rail and are electrically connected to the lifting component. The longitudinal sliding block is slidably mounted inside the fixed rail. When the sliding rail moves, it can drive the longitudinal sliding block to slide within the fixed rail. The control switch can control the working state of the lifting component.

[0007] Furthermore, the lifting assembly includes an electric telescopic rod, a lifting plate, and an L-plate. Two sets of electric telescopic rods are provided, with their bottom ends fixed to the support frame. The lifting plate is fixed to the output ends of the two sets of electric telescopic rods. Two sets of L-plates are provided, with both sets fixed to the lower surface of the lifting plate. The electric telescopic rods are electrically connected to an external power source and to a control switch. Four sets of limit bars are fixed to the L-plates with their outer sides. A sliding rail is slidably mounted on the L-plates. The electric telescopic rods control the lifting plate and L-plates to rise and fall, thereby adjusting the height of the take-up assembly.

[0008] Furthermore, the power assembly includes a fixed frame, a rotating motor, a rotating shaft, a power gear, a gear chain, and a follower slider. The fixed frame is fixedly mounted on the upper surface of the lifting plate, the rotating motor is fixedly mounted on the fixed frame and electrically connected to an external power source, and there are four sets of rotating shafts rotatably mounted on the lifting plate. The top end of one set of rotating shafts is fixedly connected to the output end of the rotating motor. There are four sets of power gears fixedly mounted at the bottom ends of the four sets of rotating shafts, and the gear chain connects the four sets of power gears. The follower slider is rotatably mounted at the bottom end of the gear chain and slides on the sliding rail. The follower slider can drive the sliding rail to move longitudinally, and the rotating motor drives the four sets of power gears to rotate synchronously through the gear chain.

[0009] Furthermore, the take-up assembly includes an adjusting lifting frame, a take-up motor, and a take-up reel. The top of the adjusting lifting frame is fixed to the bottom of the longitudinal sliding block through the opening at the bottom of the fixed rail. The take-up motor is fixed on the adjusting lifting frame and is electrically connected to an external power source. The take-up reel is rotatably mounted on the adjusting lifting frame. The output end of the take-up motor is located on the take-up reel. When the take-up motor operates, it drives the take-up reel to retrieve the bronchoscope tubing.

[0010] Furthermore, the fixing assembly includes a fixing plate, a fixing motor, threaded rods, rollers, a roller belt, a sliding lock frame, and a fixing lock frame. The fixing plate is fixedly mounted on the support frame, and the fixing motor is fixedly mounted on the fixing plate. The fixing motor is electrically connected to an external power source. There are two sets of threaded rods, one end of which is rotatably mounted on the side wall of the groove in the support frame. The other end of one set of threaded rods is fixedly mounted on the output end of the fixing motor, and the other end of the other set of threaded rods is rotatably mounted on the support frame. There are two sets of rollers, and the two sets of rollers are fixedly mounted on the two sets of threaded rods. On the rod, a roller belt connects two sets of rollers. There are two sets of sliding lock frames, which are slidably installed in the groove of the support frame. The two sets of sliding lock frames are threaded onto two sets of threaded rods. There are two sets of fixed lock frames, which are fixedly installed on the support frame. When the fixed motor rotates, it drives the two sets of threaded rods to rotate synchronously through the rollers and roller belt. The two sets of threaded rods drive the two sets of sliding lock frames to move towards the fixed lock frames, thereby clamping the patient's bronchoscope tubing and preventing the patient from shaking and causing accidents during the bronchoscopy.

[0011] This solution provides an auxiliary positioning and guidance device for bronchoscopy, which effectively solves the problem that current bronchoscopy guidance solutions on the market cannot automatically control the adjustment and start / stop of the equipment. This method brings the following advantages: (1) Set up a toothed chain and fix the follower slider below the toothed chain so that the follower slider can move circumferentially with the toothed chain, which is the basis for realizing the adjustment and movement of the take-up assembly; (2) The sliding rail is slidably placed on the L plate, and the longitudinal sliding block is slidably placed in the fixed rail. The longitudinal sliding block is fixed at the bottom of the sliding rail, so that when the sliding rail moves longitudinally back and forth, it can drive the longitudinal sliding block to move along the fixed rail direction, thereby enabling the take-up assembly to move freely in multiple directions and further adjust the position of the bronchoscope tubing. (3) The follower slider is slidably set inside the slide rail, so that when the follower slider moves on the toothed chain in a direction perpendicular to the slide rail, it can drive the slide rail to move. When the follower slider moves on the toothed chain in a direction parallel to the slide rail, the follower slider moves inside the slide rail and will not drive the slide rail to move. The follower slider moves circumferentially with the toothed chain, so that after the slide rail moves longitudinally to the boundary, it stops for a period of time and then moves in the opposite direction. After the slide rail moves to another boundary, it stops for a period of time again and repeats the above movement trajectory, thus realizing the effect of multi-directional movement adjustment of the take-up component. (4) Both sets of control switches are electrically connected to the electric telescopic rod. When the longitudinal sliding block presses the control switch, the electric telescopic rod drives the lifting plate and the wire take-up assembly to move downward. When the longitudinal sliding block does not press the control switch, the electric telescopic rod stops working, providing an automated experience. (5) When the follower slider moves to the corner along the toothed chain in the direction perpendicular to the sliding rail, the longitudinal sliding block presses one of the control switches. When the follower slider moves to the corner along the toothed chain in the direction parallel to the sliding rail, the longitudinal sliding block is always in the state of pressing the control switch. The retracting assembly moves downward to facilitate the retraction of the bronchoscope tubing after the examination. The mechanical automatic control method replaces manual control to prevent misalignment during bronchial tubing retraction, greatly improving the patient's comfort during the examination and the uniformity of the movement route during bronchial tubing retraction.

[0020] like Figures 1-3 As shown, the power assembly 4 includes a fixed frame 15, a rotating motor 16, a rotating shaft 17, a power gear 18, a gear chain 19, and a follower slider 30. The fixed frame 15 is fixedly mounted on the upper surface of the lifting plate 13.

[0021] like Figure 5 As shown, the take-up assembly 5 includes an adjusting lifting frame 20, a take-up motor 21, and a take-up reel 22. The top of the adjusting lifting frame 20 is fixed to the bottom of the longitudinal sliding block 8 through the opening at the bottom of the fixed rail 10. The take-up motor 21 is fixed on the adjusting lifting frame 20 and is electrically connected to an external power source. The take-up reel 22 is rotatably mounted on the adjusting lifting frame 20, and the output end of the take-up motor 21 is located on the take-up reel 22.

[0022] like Figure 1 , Figures 6-7 As shown, the fixing assembly 6 includes a fixing plate 23, a fixing motor 24, a threaded rod 25, a roller 26, a roller belt 27, a sliding lock frame 28, and a fixing lock frame 29. The fixing plate 23 is fixedly mounted on the support frame 1, and the fixing motor 24 is fixedly mounted on the fixing plate 23. The fixing motor 24 is electrically connected to an external power source. There are two sets of threaded rods 25. One end of each set of threaded rods 25 is rotatably mounted on the side wall of the groove in the support frame 1, and the other end of one set of threaded rods 25 is fixedly mounted on the fixing motor 26. On the output end of machine 24, the other end of another set of threaded rods 25 is rotatably mounted on support frame 1. There are two sets of rollers 26, which are fixedly mounted on the two sets of threaded rods 25. Roller belt 27 connects the two sets of rollers 26. There are two sets of sliding lock frames 28, which are slidably mounted in the groove of support frame 1. The two sets of sliding lock frames 28 are threaded onto the two sets of threaded rods 25. There are two sets of fixed lock frames 29, which are fixedly mounted on support frame 1.

[0023] In practical use, the bronchoscope tubing is placed between the sliding locking frame 28 and the fixed locking frame 29. The fixed motor 24 is turned on, which drives one set of threaded rods 25 to rotate. This set of threaded rods 25 drives the rollers 26 on them to rotate. These rollers 26, through the roller belt 27, drive another set of rollers 26 to rotate. This other set of rollers 26 drives the other set of threaded rods 25 to rotate. The two sets of threaded rods 25 drive the sliding locking frame 28 to move synchronously towards the fixed locking frame 29. When the sliding locking frame 28 and the fixed locking frame 29 allow the bronchoscope tubing to move but not to fix it, the fixed motor 24 is turned off, and the take-up motor 21 is started. The take-up reel 22 can then tighten the bronchoscope tubing through the take-up motor 21. The electric telescopic rod 1 is then activated. 2. The output end of the electric telescopic rod 12 moves downward, which in turn moves the lifting plate 13 downward. The lifting plate 13 moves the limiting strip 9 downward, which in turn moves the fixed rail 10 downward. The fixed rail 10 moves the longitudinal sliding block 8 downward, which in turn moves the adjusting lifting frame 20 downward. The adjusting lifting frame 20 moves the take-up reel 22 downward. When the take-up reel 22, carrying the bronchoscope tubing wound on it, moves to a suitable distance and position relative to the patient, the electric telescopic rod 12 is closed, and the rotating motor 16 is turned on. The rotating motor 16 drives one set of rotating shafts 17 to rotate, which in turn drives the corresponding power gear 18 to rotate. The corresponding power gear 18 drives the other three sets of power gears 18 through the gear chain 19. Rotation causes the toothed chain 19 to drive the follower slider 30 to rotate. When the follower slider 30 moves along the toothed chain 19 in a direction perpendicular to the sliding rail 7, it drives the sliding rail 7 to move longitudinally. The sliding rail 7 then drives the longitudinal sliding block 8 to slide within the fixed rail 10. The longitudinal sliding block 8 drives the adjusting lifting frame 20 to move longitudinally. The adjusting lifting frame 20 drives the take-up reel 22 and the take-up motor 21 to move longitudinally, facilitating longitudinal adjustment of the bronchoscope tubing position. When the follower slider 30 rotates to the corner of the toothed chain 19, the sliding rail 7 moves to the boundary, and the longitudinal sliding block 8 moves to the boundary. The longitudinal sliding block 8 presses one of the control switches 11, opening the electric telescopic rod 12. The end of the electric telescopic rod 12 drives the lifting plate 13 to move downwards, and the lifting plate 13 drives the motion adjustment... When component 2 moves downward, motion adjustment component 2 drives take-up component 5 downward, toothed chain 19 continues to rotate, follower slider 30 slides within slide rail 7, follower slider 30 does not drive slide rail 7 to move, toothed chain 19 continues to rotate, when follower slider 30 rotates to the other side perpendicular to slide rail 7, follower slider 30 drives slide rail 7 to move in the opposite direction, slide rail 7 drives longitudinal sliding block 8 to move in the opposite direction, longitudinal sliding block 8 loses its squeezing effect on control switch 11, electric telescopic rod 12 stops working, take-up reel 22 no longer moves downward, the position of bronchoscope tubing is adjusted again through take-up reel 22, when longitudinal sliding block 8 squeezes another set of control switches 11, electric telescopic rod 12 works again, take-up reel 22 descends again, toothed chain 19 continues to rotate.When the longitudinal sliding block 8 loses its squeezing effect on the other set of control switches 11, the electric telescopic rod 12 stops working again, and the retractor 22 stops moving downwards. This process is repeated until the bronchoscope tubing automatically adjusts to the optimal position and height, thus adapting to the actual needs of different patients.
