Description

Technical Field

[0001] This utility model relates to the field of endoscope assembly technology, and more specifically, to an auxiliary examination device for endoscope assembly. Background Technology

[0002] An optical endoscope is a tube equipped with a light that can enter the stomach through the mouth or other natural orifices into the body. It can visualize lesions that cannot be seen by X-rays, making it extremely useful for doctors. With the help of an endoscope, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly. However, the endoscope is very small in structure and plays a very important role in medical examinations. The endoscope needs to be inserted into the human body for examination. If an error occurs during the installation of the endoscope, it can threaten human health. Therefore, it is necessary to check the assembly of the endoscope. This led to the development of endoscope assembly auxiliary examination devices. However, existing endoscope assembly auxiliary examination devices still have some shortcomings that affect daily use.

[0003] The primary problem is that existing endoscopic assembly auxiliary examination devices lack insertion and removal detection devices. Each interface between the tubing and the main unit or probe is connected to a quick-connect fitting with a sealing device. Endoscope interfaces undergo hundreds to thousands of insertion and removal operations throughout their lifespan. Without such detection devices, it's impossible to determine whether the interface's snap-fit ​​processing is up to standard or whether the snap-fit ​​is properly installed. If the snap-fit ​​connection is substandard, it will not only cause the parts to lose their seal but may also damage the tubing and connectors. Manually assembled interfaces may experience excessive insertion and removal force due to variations in tightness, leading to difficulties for medical personnel. Too loose an fit may cause accidental detachment during use, while too tight an fit will result in prolonged equipment usage time.

[0004] More significantly, existing endoscopic assembly auxiliary examination devices lack a bending test device. In actual use, the endoscopic tubing needs to be bent frequently at multiple angles and at high frequencies. Without a bending test device, the following risks cannot be detected: whether the tubing and the internal transmission wire are properly connected. If the connection is not properly connected, the transmission wire may break locally under frequent bending; the outer protective device may crack during repeated bending, leading to exposed internal wires or liquid seepage; the connection joint between the tubing and the operating part may delaminate under bending stress, which is difficult to detect in initial static testing and may break suddenly during use.

[0005] Crucially, the magnifying glass assembly and stage in existing endoscope assembly auxiliary examination devices cannot be height-adjusted. The diameter and length of the endoscope tubing vary, and different specifications of tubing require specific observation distances and support heights. If the height is fixed, some specifications of tubing may not be positioned at the optimal focal plane of the magnifying glass, resulting in blurred images. Alternatively, the tubing may tilt due to a mismatch between the stage height and the tubing diameter, affecting the stability of the observation angle and making it impossible to observe whether the tubing is damaged or whether each component is properly assembled.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an auxiliary examination device for endoscope assembly, which has the following beneficial effects:

[0018] 1. A complete insertion and removal detection device is formed by the close cooperation between the air pump, solenoid valve, cylinder, piston rod and connector. The insertion and removal detection device can expose potential mechanical defects of the interface in advance by simulating the high frequency of insertion and removal actions in actual use, and avoid early failure from the source. The cylinder drives the connector to move back and forth, and repeatedly inserts and removes the connector with the endoscope. The inspectors check whether the connector is installed in place by the sound and feel produced during docking.

[0019] 2. A complete bending test device is formed by the tight cooperation between the rocker arm, rotating disk, bending column, connecting column, and bearing. The hose bending test device simulates bending scenarios in actual use, and can comprehensively test the reliability of the internal and external structure of the hose. By setting different bending angles and cycles, it can detect whether there are processing defects or improper installation problems in the buckles at the connection between the hose and the connector, so as to avoid sealing failure and mechanical damage to the hose and connector caused by loose buckles. For core components such as transmission steel wires, optical fiber bundles, and wires inside the hose, continuous bending tests can detect whether there are hidden defects, and whether the internal parts are properly installed with the hose.

[0020] 3. A complete height-adjustable inspection device is formed by the tight cooperation between the fixed column, placement platform, adjustment frame, magnifying glass, elastic collar, threaded column, locking nut, and tightening head. Endoscope tubing varies significantly in diameter, length, and structural shape. The height-adjustable design can specifically adapt to the inspection needs of different specifications of products. The height adjustment of the magnifying glass assembly can match its focal length range. By finely adjusting the magnifying glass height, the part of the tubing to be inspected can be precisely locked within the focal plane, avoiding image blurring caused by object distance deviation and enabling clear identification of minute defects. The height of the placement platform can be adjusted according to the shape of the tubing. For example, when inspecting tubing with a connector, the placement platform is raised to make the connector horizontal; when inspecting extra-long tubing, the height of the placement platform is lowered to prevent the inspection point from shifting due to tubing sagging.

[0030] Please see Figures 1-5 An auxiliary inspection device for endoscopic assembly includes a base 1. The base 1 is equipped with an insertion / removal detection device, a bending test device, and a height adjustment inspection device. The insertion / removal detection device includes an air pump 2, a solenoid valve 3, a cylinder 4, a piston rod 5, and a connector 6. The air pump 2 and the cylinder 4 are both fixedly mounted on the base 1. The solenoid valve 3 is connected to the cylinder 4 and the air pump 2 respectively through pipes. The piston rod 5 is movably connected to the cylinder 4, and the connector 6 is fixedly connected to the piston rod 5. The bending test device includes a rocker arm 7, a rotating disk 8, a bending column 9, a connecting column 10, and a bearing 11. The rocker arm 7 is fixedly connected to the rotating disk 8. The bending column 9 is fixedly connected to the rotating disk 8 and has a gap with the rocker arm 7. Multiple bending columns 9 are provided. The connecting column 10 is fixedly connected to the rotating disk 8 and to the inner ring of the bearing 11. The outer ring of the bearing 11 is fixedly connected to the base 1.

[0031] In a further embodiment of this application, the height adjustment inspection device includes a fixed column 12, a placement platform 13, an adjustment frame 14, a magnifying glass 15, and an adjustment assembly. There are two fixed columns 12, both of which are fixedly connected to the base 1. The fixed columns 12 are movably connected to the adjustment assembly. There are multiple adjustment assemblies, and each adjustment assembly is fixedly connected to the placement platform 13 or the adjustment frame 14. The magnifying glass 15 is rotatably connected to the adjustment frame.

[0032] In a further embodiment of this application, the base 1 is provided with a hose fixing device, which includes a fixing seat 16 and an elastic clip 17. The fixing seat 16 is fixedly connected to the elastic clip 17 and the base 1 respectively. The elastic clip 17 and the connector 6 have a gap and are at the same horizontal axis height. When the interface end of the endoscope hose is inserted into the elastic clip 17 on the fixing seat 16, the endoscope can maintain a stable placement point when the connector 6 is inserted and removed from the endoscope interface.

[0033] In a further embodiment of this application, the adjustment assembly includes an elastic collar 18, a threaded post 19, and a tightening head 20. The tightening head 20 is fixedly connected to the threaded post 19, and the threaded post 19 is threadedly connected to the elastic collar 18. One end of the elastic collar 18 is provided with a locking nut 21, which is threadedly connected to the threaded post 19. By rotating the tightening head 20, the threaded post 19 can rotate around the elastic collar 18 and the locking nut 21, thereby making the elastic collar 18 tightly contact or separate from the fixed post 12. This allows the placement platform 13 and the adjustment frame 14 to be adjusted in height along the fixed post 12, enabling the magnifying glass 15 to better observe whether the endoscope components are installed in place and whether there is any damage to the exterior.

[0034] In a further embodiment of this application, the base 1 is provided with a support column 22 and a support pad 23, and the base 1 is provided with a lighting lamp 24. The support column 22 and the support pad 23 make the base 1 more stable, and the lighting lamp 24 enables the magnifying glass 15 to better observe and inspect.

[0035] In this embodiment, when the device is needed, the interface end of the endoscope tubing is inserted into the elastic clip 17 on the fixing base 16. The elastic clip 17 is held by hand to make the interface end more stable. The air pump 2 is started so that the gas enters the cylinder 4 through the solenoid valve 3, causing the piston rod 5 with the connector 6 to reciprocate, so that the connector 6 is inserted into the interface of the endoscope tubing and then pulled out. This process is repeated to check whether the interface end is installed firmly. After the check is completed, the endoscope tubing is taken out from the elastic clip 17. Then, a certain length of endoscope tubing is selected and passed through the gap between the bending columns 7. The rocker arm 7 is rotated back and forth to make the rotating disk 8 rotate forward and backward around the bearing 11 through the connecting column 10. The forward and reverse rotation of the rotating disk 8 causes the endoscope tubing to be repeatedly bent by the obstruction between the bending columns 9. After checking this length, other lengths are checked until the entire tubing is bent and checked, so as to verify whether the components inside the endoscope tubing are installed in place.

[0036] More specifically, after bending and plugging / unplugging checks, the endoscope is placed on the placement platform 13. By rotating the tightening head 20, the threaded post 19 rotates around the elastic collar 18 and the locking nut 21, which allows the elastic collar 18 to be in close contact with or separated from the fixed post 12. This allows the placement platform 13 and the adjustment frame 14 to be adjusted in height along the fixed post 12, enabling the magnifying glass 15 to better observe whether the endoscope components are installed in place and whether there is any damage to the exterior. The lighting lamp 24 enables the magnifying glass 15 to observe better, and the support post 22 and the support pad 23 make the base 1 more stable.

[0037] In summary, during use or operation of the entire device, insert the endoscope tubing into the elastic clip 17 on the fixed base 16, and hold the elastic clip 17 by hand to stabilize the endoscope tubing. Start the air pump 2 to allow gas to enter the cylinder 4 through the solenoid valve 3, causing the piston rod 5 with the connector 6 to reciprocate, inserting the connector 6 into the endoscope tubing and then pulling it out. Repeat this process to check if the endoscope tubing is securely installed. After checking, remove the endoscope tubing from the elastic clip 17, and then select a certain length of endoscope tubing to pass through the gap between the bending columns 7. Rotate the rocker arm 7 back and forth to make the rotating disk 8 rotate forward and backward around the bearing 11 via the connecting column 10. The forward and reverse rotation of the rotating disk 8 causes the endoscope tubing to be repeatedly bent by the obstruction between the bending columns 9. After checking this length, verify other lengths until the entire tubing is bent and checked, thereby verifying whether the components inside the endoscope tubing are installed properly.

[0038] After bending and unplugging checks, the endoscope is placed on the placement platform 13. By rotating the tightening head 20, the threaded post 19 rotates around the elastic collar 18 and the locking nut 21, which allows the elastic collar 18 to be in close contact with or separated from the fixed post 12. This allows the placement platform 13 and the adjustment frame 14 to be adjusted in height along the fixed post 12, enabling the magnifying glass 15 to better observe whether the endoscope components are installed in place and whether there is any damage to the exterior. The lighting lamp 24 enables the magnifying glass 15 to observe better, and the support post 22 and the support pad 23 make the base 1 more stable.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
