Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and in particular to an endoscope insertion auxiliary tool and an endoscope device. Background Art

[0002] Endoscope insertion aids play a vital role in endoscopic examinations and treatments. They help doctors more smoothly and safely insert endoscopes into patients, enabling precise observation and manipulation. The tubular portion of the tool with a lumen facilitates the insertion of the endoscope's lens and tube.

[0003] Endoscopes play a vital role in oral healthcare, providing multiple functions, including image acquisition, lesion localization, diagnostic assistance, treatment planning, and efficacy evaluation. Passing through a soft, flexible tube, the endoscope can magnify and clearly display various oral structures, including the teeth, gums, tongue, and throat. This helps doctors observe difficult-to-see areas, such as deep gums and tooth roots, and diagnose possible lesions such as caries, periodontitis, oral ulcers, wisdom tooth inflammation, edentulous and tooth loss, and various oral mucosal diseases.

[0004] When used in the oral cavity, the patient lies on a reclining chair, then holds the endoscope close to the oral cavity and inserts the endoscope along the tool. This process requires the handheld tool to remain stable, which is quite inconvenient. The reclining chair has a headrest, but it does not provide support for the back of the neck, reducing user comfort. Therefore, an endoscope insertion assist tool and an endoscope device have been proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the background technology and to propose an endoscope insertion auxiliary tool and an endoscope device.

[0006] The rear end of the support plate is connected to the support bracket by an elastic mechanism, and a pushing mechanism is arranged between the upper surface of the support plate and the side end face of the support plate.

[0007] Preferably, the universal clamping member comprises a universal sleeve fixedly connected to the front end of the arc frame, a universal ball slidably engaged within the inner side of the universal sleeve, a universal rod fixedly connected to the outer surface of the universal ball, one end of the universal rod fixedly connected to a connecting frame, and a clamping mechanism disposed on one side of the connecting frame. The universal ball can slide within the inner side of the universal sleeve, thereby adjusting the angle of the universal rod and thus changing the angle of the clamping mechanism.

[0008] Preferably, the clamping mechanism includes two V-shaped plates that slide into the inner side of the connecting frame. A second threaded rod is rotatably inserted into the inner side of the connecting frame, and the second threaded rod is threaded through the two V-shaped plates. When the two V-shaped plates are close together, they can more stably clamp the surface of the guide tube, facilitating the subsequent insertion of the endoscope lens and the tank body through the guide tube for positioning, guidance and transportation.

[0009] Preferably, the pressing mechanism includes a concave seat fixedly connected to the upper surface of the connecting seat, the inner top surface of the concave seat is fixedly connected to a fixing column, the outer surface of the fixing column is sleeved with a compression spring, the fixing column slides through the upper surface of the pressure plate, the pressure plate slides through the inner side of the concave seat, and the compression spring is located on the upper surface of the pressure plate.

[0010] Preferably, the distance adjustment mechanism includes a sliding groove formed on a side surface of the connecting seat, the movable clamping plate slides into the inner side of the sliding groove, a first threaded rod is rotatably passed through the inner side of the sliding groove, and the first threaded rod is threadedly passed through the inner side of the movable clamping plate. When the first threaded rod rotates, the movable clamping plate will slide along the inner side of the sliding groove.

[0011] Preferably, a movable column is fixedly connected to the rear end of the arc frame, and the upper and lower ends of the movable column are respectively slidably engaged with the inner sides of the pressure rail and the fixed rail. The movable column can slide or rotate along the pressure rail and the fixed rail.

[0012] Preferably, the elastic mechanism includes a plurality of compression springs fixedly connected to the rear surface of the sliding plate, and the rear ends of the compression springs are fixedly connected to the front surface of the pressing block. The compression springs can ensure that the pressing block is tightly pressed against the surface of the backrest insert to prevent the movable clamp from loosening.

[0013] Preferably, the pushing mechanism includes a sliding opening formed on the upper surface of the connecting cylinder, a sliding plate fixedly connected to the rear edge of the upper surface of the support plate, the sliding plate slidingly passing through the inner side of the sliding opening, a pressure column fixedly connected to one side surface of the sliding plate, a connecting plate fixedly connected to the lower edge of the end surface of the movable clamping plate, a T-shaped column slidingly passing through the upper surface of the connecting plate, a return spring sleeved on the outer surface of the T-shaped column, an inclined plate fixedly connected to the upper end of the T-shaped column, and the pressure column contacting the upper surface of the inclined plate. When the pressure column moves backward, it pushes the inclined plate, thereby squeezing the return spring, and the return spring exerts a downward elastic force on the pressure plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can clamp the movable clamping plate and the fixed clamping plate on the surface of the backrest inserting plate, and then rotate the second threaded rod to move the movable clamping plate, ensuring that the movable clamping plate and the fixed clamping plate can be clamped on the surface of the backrest inserting plate. Then, the guide tube is arranged between the two V-shaped plates, and then the second threaded rod is rotated to make the two V-shaped plates approach each other, thereby clamping the guide tube. By applying a certain external force, the pressure rail is moved up, the pressure spring is squeezed, and the pressure rail relaxes the moving column, so that the arc frame can be rotated with the moving column as the axis. At the same time, the moving column can be relatively moved horizontally between the pressure rail and the fixed rail, providing two degrees of adjustment freedom for the guide tube. In addition, applying a certain external force can make the connecting frame rotate relative to the universal ball as the center, adjust the angle of the guide tube, and make the adjustment more flexible.

[0016] 2. In the present invention, when the person to be tested lies on the seat, the back of his head rests on the pillow. At this time, the back of his neck rests on the surface of the pillow, which improves the comfort of use;

[0017] 3. When the back of the user's neck presses against the headrest, the present invention causes the support plate to move backward, squeezing the compression spring, which in turn causes the pressing block to press against the surface of the backrest insert, effectively preventing the movable clamp from loosening and ensuring clamping stability. As the support plate moves backward, the pressure column pushes against the surface of the inclined plate, causing the T-shaped column to move downward, squeezing the return spring. The return spring applies a downward force to the connecting plate, and the downward force of the pressure plate acts on the pressure rail, improving the stability of the movable column, and thus improving the stability of the arc frame and the guide tube. Therefore, the stability of the guide tube can be ensured when the person to be tested is in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0029] like Figures 1-9 The endoscope insertion auxiliary tool and endoscope device shown include an arc frame 1, a universal clamping part for positioning the guide tube 34 is provided at the front end of the arc frame 1, a connecting seat 2 is provided at the rear end of the arc frame 1, one side surface of the connecting seat 2 is fixedly connected to the fixed rail 3, the upper side of the connecting seat 2 is inserted with a pressure plate 6 through a pressing mechanism, and one end of the lower surface of the pressure plate 6 is fixedly connected to the pressure rail 4, and the rear end of the arc frame 1 is clamped between the pressure rail 4 and the fixed rail 3. The other side surface of the connecting seat 2 is fixedly connected to the fixed clamping plate 10, and the other side surface of the connecting seat 2 and the front of the fixed clamping plate 10 are connected to the movable clamping plate 11 through a distance adjustment mechanism. The front surface of the movable clamping plate 11 is slidably inserted with a support plate 14, the front end of the support plate 14 is fixedly connected to the support bracket 20, and the rear end of the support plate 14 is connected to the clamping block 16 through an elastic mechanism, and a pushing mechanism is provided between the upper surface of the support plate 14 and the side end face of the pressure plate 6.

[0030] like Figure 7 、 Figure 8As shown, the universal clamping member includes a universal sleeve 29 fixedly connected to the front end of the arc frame 1. A universal ball 31 is slidably engaged within the inner side of the universal sleeve 29. A universal rod 30 is fixedly connected to the outer surface of the universal ball 31. One end of the universal rod 30 is fixedly connected to the connecting frame 26, and a clamping mechanism is provided on one side of the connecting frame 26. The universal ball 31 can slide within the inner side of the universal sleeve 29, thereby adjusting the angle of the universal rod 30 and thus changing the angle of the clamping mechanism.

[0031] The clamping mechanism includes two V-shaped plates 28 that slide into the inside of the connecting frame 26. A second threaded rod 27 is rotatably inserted into the inside of the connecting frame 26. The second threaded rod 27 threadably penetrates the two V-shaped plates 28. The threads on the surface of the second threaded rod 27 are symmetrical. When the second threaded rod 27 rotates, the two V-shaped plates 28 move closer or further away from each other. When the two V-shaped plates 28 are close together, they can more stably clamp the surface of the guide tube 34, facilitating the subsequent insertion of the endoscope lens and the tank body through the guide tube 34 for positioning, guidance and transportation.

[0032] like Figure 6 As shown, a movable column 5 is fixedly connected to the rear end of the arc frame 1, and the upper and lower ends of the movable column 5 are respectively slidably engaged with the inner sides of the pressing rail 4 and the fixed rail 3. The movable column 5 can slide or rotate between the pressing rail 4 and the fixed rail 3.

[0033] like Figure 5 As shown, the pressing mechanism includes a concave seat 7 fixedly connected to the upper surface of the connecting seat 2, a fixed column 8 fixedly connected to the inner top surface of the concave seat 7, and a compression spring 9 sleeved on the outer surface of the fixed column 8. The fixed column 8 slides through the upper surface of the pressure plate 6, and the pressure plate 6 slides through the inner side of the concave seat 7. The compression spring 9 is located on the upper surface of the pressure plate 6. The compression spring 9 presses on the surface of the pressure plate 6 to ensure that the pressure rail 4 can be pressed against the upper end surface of the movable column 5. When the pressure rail 4 is pulled up, the movable column 5 can be adjusted to rotate or move laterally.

[0034] The distance adjustment mechanism includes a slide groove 12 formed on the side surface of the connecting base 2. The movable clamping plate 11 slides into the inner side of the slide groove 12. A first threaded rod 13 is rotated through the inner side of the slide groove 12. The first threaded rod 13 is threaded through the inner side of the movable clamping plate 11. When the first threaded rod 13 rotates, the movable clamping plate 11 will slide along the inner side of the slide groove 12.

[0035] like Figure 4 As shown, the elastic mechanism includes a plurality of compression springs 19 fixedly connected to the rear surface of the sliding plate 17, and the rear end of the compression spring 19 is fixedly connected to the front surface of the pressing block 16. The compression spring 19 can ensure that the pressing block 16 is tightly pressed against the surface of the backrest insert 33 to prevent the movable clamping plate 11 from loosening.

[0036] like Figure 2 、 Figure 3As shown, the pushing mechanism includes a sliding opening 18 opened on the upper surface of the connecting tube 15, a sliding plate 17 is fixedly connected to the rear edge of the upper surface of the support plate 14, the sliding plate 17 slides through the inner side of the sliding opening 18, and a pressure column 25 is fixedly connected to one side surface of the sliding plate 17. A connecting plate 21 is fixedly connected to the lower edge of the end surface of the movable clamping plate 11, and a T-shaped column 22 slides through the upper surface of the connecting plate 21. The outer surface of the T-shaped column 22 is sleeved with a return spring 23, and the upper end of the T-shaped column 22 is fixedly connected to an inclined plate 24. The pressure column 25 contacts the upper surface of the inclined plate 24. When the pressure column 25 moves backward, it will push the inclined plate 24, thereby squeezing the return spring 23, and the return spring 23 will give the pressure plate 6 a downward elastic force.

[0037] The second threaded rod 27 is then rotated to move the movable clamping plate 11 and the fixed clamping plate 10 to the surface of the backrest inserting plate 33, and then the guide tube 34 is arranged between the two V-shaped plates 28. Then, by rotating the second threaded rod 27, the two V-shaped plates 28 are brought close to each other, thereby clamping the guide tube 34. By applying a certain external force, the pressure rail 4 is moved up, the pressure spring 9 is squeezed, and the pressure rail 4 is relaxed. After the movable column 5, the arc frame 1 can be rotated about the movable column 5 as the axis, and the movable column 5 can be relatively moved horizontally between the pressure rail 4 and the fixed rail 3, providing two degrees of adjustment freedom for the guide tube 34. In addition, applying a certain external force can make the connecting frame 26 rotate relative to the universal ball 31 as the center, and adjust the angle of the guide tube 34, which is more flexible. Figure 8 、 Figure 9 shown.

[0038] After the person to be tested lies on the seat 35, the back of the head rests on the pillow 32. At this time, the back of the neck rests on the surface of the pillow 32. When the back of the neck presses the pillow 32, the support plate 14 moves backward, squeezing the compression spring 19, and then the pressing block 16 is pressed against the surface of the backrest insert 33, effectively preventing the loosening of the movable clamp 11 and ensuring the stability of the clamping. When the support plate 14 moves backward, the pressure column 25 pushes the surface of the inclined plate 24, causing the T-shaped column 22 to move downward, squeezing the return spring 23. The return spring 23 applies a downward pressure to the connecting plate 21. The downward pressure of the pressure plate 6 acts on the pressure rail 4, improving the stability of the movable column 5, and then improving the stability of the arc frame 1 and the guide tube 34. Therefore, the stability of the guide tube 34 can be ensured when the person to be tested is in use.
