Description

Technical Field

[0001] This invention specifically relates to an airway interventional intubation tool. Background Technology

[0002] Tracheal intervention is a minimally invasive endoscopic diagnostic and treatment technique in respiratory medicine. It typically involves using a bronchoscope inserted through the nose or mouth into the trachea and bronchi to perform procedures without open-chest surgery. This procedure is primarily used for the diagnosis and treatment of airway diseases. Under direct visualization, doctors can perform procedures such as biopsy sampling, removal of airway foreign bodies, dilation of narrowed airways, placement of airway stents, ablation of proliferative lesions, and removal of airway secretions and necrotic tissue.

[0003] For example, Chinese patent CN221513161U discloses an airway intervention endotracheal intubation fixation device. This device inserts the trachea containing the bronchoscope through the first fixing ring and all the second fixing rings into the appropriate position. Rotating the second handle pushes the second piece to the left through the first screw, so that the first and second pieces are tightly attached to the bronchoscope, thus clamping the bronchoscope. Then, rotating the third handle pushes the fourth piece to the left through the second screw, so that the third and fourth pieces are tightly attached to the outer wall of the trachea, thus clamping the trachea. When it is necessary to withdraw the bronchoscope, the trachea is not easily pulled out of the patient's airway along with the bronchoscope, reducing the number of steps for the operator.

[0004] However, most current clinical endotracheal intubation tools are operated manually, relying primarily on medical staff to hold the intubation tube and perform intubation and alignment based on their personal experience and skill. This method is highly dependent on human experience; different medical staff have different techniques, pushing force, and speed, making it easy for novice medical staff to make operational errors. It also suffers from poor versatility and stability. Furthermore, manual pushing makes it difficult to precisely control the insertion depth, and fine-tuning the stroke during the pushing process is challenging, often resulting in insufficient insertion depth, excessive insertion, or misalignment. To ensure accurate intubation, the insertion depth needs to be repeatedly adjusted during clinical procedures, significantly increasing intubation time, reducing diagnostic and treatment efficiency, and easily causing friction and irritation to the patient's airway mucosa, leading to complications such as airway injury and laryngeal edema. Therefore, this paper proposes an endotracheal intubation tool to address these problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a new airway interventional intubation tool, which addresses the problem that most existing intubation tools for tracheal intervention rely on the skill and experience of medical staff, making it inconvenient to accurately control the intubation depth after intubation and requiring repeated adjustments to the intubation depth during the intubation process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tracheal interventional intubation tool, comprising a cover, two sets of clamping seats slidably disposed on one side of the cover, a clamping arc surface being provided between the two sets of clamping seats, and a delivery unit disposed within the clamping seats, the delivery unit comprising: Two sets of conveyor rollers, each rotatably mounted within the clamping seat, are connected by a conveyor belt that protrudes from the clamping arc surface. A drive mechanism is disposed on the clamping seat and connected to one of the sets of conveying rollers to drive the set of conveying rollers to rotate; A fine-tuning mechanism, mounted on the clamping seat and connected to another set of the conveyor rollers, drives the other set of conveyor rollers to rotate at a reduced speed and self-lock; and A display mechanism is provided on the clamping seat to display the rotation distance of the two sets of conveying rollers respectively.

[0007] In one embodiment, two sets of upright plates are provided on one side of the cover, and two sets of clamping seats are slidably disposed between the two sets of upright plates. The upright plates are also provided with opening and closing components for driving the two sets of clamping seats to open and close.

[0008] In one embodiment, the opening / closing component includes: A drive frame is slidably mounted on one side of the upright plate. Two sets of sliders are mounted on the drive frame, and a drive column is mounted on one side of each slider. A sliding groove is formed on the upright plate, and the slider is slidably engaged within the sliding groove; and An inclined groove is formed on one side of the clamping seat, and both ends of the groove are connected to a flat groove. The drive column is engaged in one of the flat grooves.

[0009] In one embodiment, the clamping seats are rotatably provided with two sets of toothed discs on opposite surfaces. The two sets of toothed discs are respectively connected to the two sets of conveying rollers through a first bevel gear pair. After the two sets of clamping seats are closed, the two sets of toothed discs arranged opposite each other are engaged.

[0010] In one embodiment, the drive mechanism includes: A first knob is rotatably mounted on the clamping seat; and A rotating shaft is mounted on one of the set of conveying rollers and is connected to the first knob via a second bevel gear pair.

[0011] In one embodiment, the fine-tuning mechanism includes: A drive rod is slidably threaded along its axis through one of the set of conveying rollers; A fixing component, disposed on the clamping seat, is provided to selectively lock or unlock the lateral sliding of the transmission rod; and A power assembly for connection to the drive rod after the drive rod is locked.

[0012] In one embodiment, the fixing component includes: A first abutment plate is disposed at the end of the transmission rod; The second abutment plate is slidably disposed within the clamping seat along its axis and is arranged opposite to the first abutment plate; and A propulsion unit is disposed on the clamping seat and connected to the second abutment plate to drive the second abutment plate to slide and be fixed.

[0013] In one embodiment, the propulsion unit includes: The second knob is rotatably mounted on the clamping seat; A drive sleeve, disposed at the end of the second knob, has a spiral groove on it, both ends of which are connected to arc-shaped grooves; and The push column is disposed on the second abutment plate and is engaged in one of the set of arc-shaped grooves.

[0014] In one embodiment, the power assembly includes: The first sawtooth disc is located at the other end of the transmission rod; The baffle is connected to the conveying roller via a connecting sleeve, and an elastic element is provided between it and the first toothed disc. A second toothed disc is rotatably disposed within the clamping seat and engages with the first toothed disc; a worm gear is provided on the second toothed disc; and The third knob is rotatably mounted on the clamping seat and connected to a worm gear, which meshes with the worm wheel.

[0015] In one embodiment, the display mechanism includes: A circular scale line is arranged on one side of the clamping base, and the third knob is located on one side of the circular scale line; A lead screw is disposed at the end of one set of the conveying rollers; An indicator frame is slidably disposed within the clamping seat and screwed to the lead screw. The clamping seat has a through slot, through which the indicator frame passes and is connected to the indicator base. Straight graduation lines are arranged on one side of the through groove.

[0016] Compared with the prior art, the present invention has at least the following advantages: During use, the end of the tube is inserted into the shroud through the gap between two sets of clamps. The clamps are then closed to hold the tube in place by two conveyor belts. Independent drive and fine-tuning mechanisms allow for both regular, uniform tube delivery and precise speed reduction, catering to the needs of rapid initial insertion and precise positioning later. This avoids the problems of uneven force and speed control associated with traditional manual insertion, which can lead to excessive or incomplete insertion. A display mechanism provides real-time, accurate feedback on the rotation distance of the two conveyor rollers, offering clear indication of the insertion depth and allowing medical staff to monitor the progress without repeated adjustments. The fine-tuning mechanism has a self-locking function, locking the conveyor structure after adjustment to prevent tube misalignment, effectively improving insertion accuracy and stability, significantly reducing intraoperative adjustments, shortening surgical time, and lowering the risk of airway injury.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Example:

[0024] Please see Figures 1 to 3This invention provides an airway interventional intubation tool, including a cover 1. Two sets of clamping seats 3 are slidably arranged on one side of the cover 1, and a clamping arc surface 10 is provided between the two sets of clamping seats 3. Two sets of upright plates 2 are arranged on one side of the cover 1, and the two sets of clamping seats 3 are slidably arranged between the two sets of upright plates 2. An opening and closing assembly for driving the two sets of clamping seats 3 to open and close is also provided on the upright plate 2. The opening and closing assembly includes a drive frame 6 that can be slidably arranged on one side of the upright plate 2. Two sets of sliders 8 are arranged on the drive frame 6. A drive column 9 is provided on one side of the sliders 8. A sliding groove 7 is opened on the upright plate 2, and the sliders 8 are slidably locked in the sliding groove 7. An inclined groove 4 is opened on one side of the clamping seat 3, and both ends of the inclined groove 4 are connected to flat grooves 5. The drive column 9 is locked in one of the flat grooves 5.

[0025] In the initial state, the two sets of clamping seats 3 are in the open state. The tube with insertion cannula is inserted into the cover 1 through the gap between the two sets of clamping seats 3. Then, the drive frame 6 is moved to drive the two sets of sliders 8 to move in the slide groove 7. The arrangement of the drive column 9 and the inclined groove 4 controls the two sets of clamping seats 3 to close to clamp the tube. The arrangement of the drive column 9 and the flat groove 5 locks the position of the two sets of clamping seats 3 to prevent the two sets of clamping seats 3 from opening during subsequent surgery, thereby quickly completing the installation of the tube.

[0026] Please see Figure 2 , 4 7. In this embodiment, a conveying unit is provided inside the clamping seat 3. The conveying unit includes two sets of rotatable conveying rollers 13 arranged inside the clamping seat 3. The two sets of conveying rollers 13 are connected by a conveyor belt 14. The conveyor belt 14 protrudes from the clamping arc surface 10. Two sets of toothed discs 25 are rotatably arranged on opposite surfaces of the clamping seat 3. The two sets of toothed discs 25 are respectively connected to the two sets of conveying rollers 13 through a first bevel gear pair 24. After the two clamping seats 3 are closed, the two sets of toothed discs 25 arranged opposite to each other are engaged.

[0027] After the pipeline is installed, the conveyor belt 14, together with the conveyor rollers 13, clamps the pipeline. By controlling the rotation of one set of conveyor rollers 13, the conveyor belt 14 can be driven to move in a circumferential direction to transport the pipeline. After the two sets of clamping seats 3 are closed, the toothed discs 25 on the two sets of clamping seats 3 engage with each other. This allows the synchronous movement of the two sets of conveyor belts 14 to be controlled by only controlling the rotation of one set of conveyor rollers 13. The engaging form of the toothed discs 25 allows the force to be transmitted laterally, preventing the two sets of clamping seats 3 from separating and causing the friction between the conveyor belt 14 and the pipeline to decrease and relative slippage to occur, thus improving the accuracy of pipe insertion control.

[0028] Please see Figure 4In this embodiment, the conveying unit further includes a drive mechanism mounted on the clamping seat 3. The drive mechanism is connected to one set of conveying rollers 13 to drive the set of conveying rollers 13 to rotate. The drive mechanism includes a first knob 18 rotatably mounted on the clamping seat 3. One set of conveying rollers 13 is provided with a rotating shaft 16, and the rotating shaft 16 is connected to the first knob 18 through a second bevel gear pair 17. By rotating the first knob 18 and driving one set of conveying rollers 13 to rotate through the second bevel gear pair 17, the conveyor belt 14 can rotate rapidly, thereby enabling rapid insertion of the pipe in the early stage of pipe placement.

[0029] Please see Figures 3 to 6 In this embodiment, the conveying unit further includes a fine-tuning mechanism disposed on the clamping seat 3. The fine-tuning mechanism is connected to another set of conveying rollers 13 to drive the set of conveying rollers 13 to rotate at a reduced speed and self-lock. The fine-tuning mechanism includes a transmission rod 26 that is slidably disposed along its axis on one of the set of conveying rollers 13. The clamping seat 3 is provided with a fixing component that can selectively lock or unlock the lateral sliding of the transmission rod 26. The fixing component includes a first abutment plate 27 disposed at the end of the transmission rod 26. A second abutment plate 38 is slidably disposed in the clamping seat 3 along its axis. The second abutment plate 38 is arranged opposite to the first abutment plate 27. The clamping seat 3 is provided with a pushing part connected to the second abutment plate 38. The pushing part drives the second abutment plate 38 to slide and fix.

[0030] The propulsion unit includes a second knob 34 rotatably mounted on the clamping seat 3. The end of the second knob 34 is provided with a drive sleeve 35. The drive sleeve 35 is provided with a spiral groove 36. Both ends of the spiral groove 36 are connected to arc grooves 37. The second abutment plate 38 is provided with a propulsion column 39, which is engaged in one of the arc grooves 37.

[0031] The fine-tuning mechanism also includes a power assembly, which is connected to the transmission rod 26 after the transmission rod 26 is locked. The power assembly includes a first toothed disc 28 located at the other end of the transmission rod 26, a baffle 23 connected to the conveying roller 13 via a connecting sleeve 22, an elastic element 29 between the baffle 23 and the first toothed disc 28, a second toothed disc 30 rotatably located inside the clamping seat 3, the second toothed disc 30 engaging with the first toothed disc 28, a worm gear 31 located on the second toothed disc 30, and a third knob 33 rotatably located on the clamping seat 3, the third knob 33 being connected to a worm 32, the worm 32 meshing with the worm gear 31.

[0032] Before the rapid insertion of the pipe, the second abutment plate 38 and the first abutment plate 27 are arranged at intervals. During the rotation of the conveying roller 13, the first toothed disc 28 is driven to rotate, and the inclined surface of the teeth on one side of the first toothed disc 28 and the second toothed disc 30 pushes the transmission rod 26 to slide. A certain space is reserved for the movement of the transmission rod 26 to avoid interference between the structures. When the pipe needs to be fine-tuned, the second knob 34 is turned to control the sliding of the second abutment plate 38 to abut against the first abutment plate 27 through the cooperation of the spiral groove 36 and the push column 39, thereby locking the sliding of the transmission rod 26 so that it can only rotate. Then, the third knob 33 is turned to drive the worm gear 32 to rotate, which in turn drives the second toothed disc 30 to rotate through the worm wheel 31. Since the first toothed disc 28 cannot slide, the second toothed disc 30 can push the first toothed disc 28 to rotate through the inclined surface of the teeth during the rotation, so that the corresponding conveying roller 13 rotates at a reduced speed and self-locks, making it easier to control the insertion distance of the pipe.

[0033] Please see Figure 2 , 4 In this embodiment, the conveying unit also includes a display mechanism disposed on the clamping seat 3, which displays the rotation distance of the two sets of conveying rollers 13 respectively. The display mechanism includes an annular scale line 12 arranged on one side of the clamping seat 3, and a third knob 33 located on one side of the annular scale line 12. One set of conveying rollers 13 is provided with a lead screw 19 at its end. An indicator frame 20 is slidably disposed in the clamping seat 3 and screwed to the lead screw 19. A through groove 15 is provided on the clamping seat 3. The indicator frame 20 passes through the through groove 15 and is connected to an indicator seat 21. A straight scale line 11 is arranged on one side of the through groove 15.

[0034] The rotation distance of the worm 32 can be accurately determined through the annular scale line 12, so as to accurately control the insertion depth. During the rotation of the conveying roller 13, the lead screw 19 can be rotated, thereby causing the indicator seat 21 to slide, so that the length of the early rapid tube placement can be determined through the linear scale line 11.

[0035] Specific usage and beneficial effects of the present invention: During use, the intubation tool inserts the end of the tube into the housing 1 through the gap between two sets of clamping seats 3. The clamping seats 3 are then closed to clamp the tube with two sets of conveyor belts 14. Independently designed drive and fine-tuning mechanisms allow for both regular, uniform tube delivery and precise speed reduction adjustments, adapting to the needs of rapid initial insertion and precise positioning later. This avoids the problems of uneven force and speed control associated with traditional manual intubation, which can lead to excessive or incomplete insertion. A display mechanism accurately shows the rotation distance of the two sets of conveyor rollers 13 in real time, providing intuitive feedback on the insertion depth and allowing medical staff to monitor the progress without repeated adjustments. The fine-tuning mechanism has a self-locking function, locking the conveyor structure after fine-tuning to prevent tube displacement, effectively improving intubation accuracy and stability, significantly reducing intraoperative adjustments, shortening surgical time, and lowering the risk of airway injury.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
