Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multi-angle adjustable lighting auxiliary device for nasal endoscope examination. Background Technology

[0002] In the clinical diagnosis of otolaryngology, rhinoscopy is an extremely important and commonly used diagnostic tool. Through rhinoscopy, doctors can directly observe the internal tissue structure and lesions of the nasal cavity, providing crucial evidence for accurate diagnosis. During rhinoscopy, good lighting conditions are one of the key factors to ensure the accuracy and effectiveness of the examination. Sufficient and precise lighting allows doctors to clearly observe the subtle structures and lesion features inside the nasal cavity. Therefore, a multi-angle adjustable lighting auxiliary device for rhinoscopy is designed.

[0003] Existing nasal endoscope lighting equipment cannot precisely adjust the position and angle of the light source according to the differences in the patient's nasal cavity structure and the needs of different examination sites and angles. This often results in insufficient lighting in some areas of the nasal cavity or poor light angle, making it difficult for doctors to clearly observe the details of lesions and affecting the accuracy of diagnosis. Furthermore, the existing nasal endoscope lighting equipment has a simple and crude fixing method and cannot be adjusted according to the user's head size. During long-term examinations, problems such as loosening and displacement are likely to occur. Utility Model Content

[0020] In this embodiment of the disclosure, The seat plate 1 is fixed with fixing straps 11 on both the left and right sides. The fixing straps 11 are equipped with adhesive tape 111. The rear ends of the two fixing straps 11 are connected to the rear contact plate 12. The rear contact plate 12 is connected to the first elastic band 121. The seat plate 1 is connected to the second elastic band 13. The first elastic band 121 and the second elastic band 13 are connected to the upper contact plate 14. Both the rear contact plate 12 and the upper contact plate 14 are provided with ventilation holes. Their functions are: the fixing straps 11 and the adhesive tape 111 can be adjusted according to the user's head size to achieve personalized wearing; the combination of the first elastic band 121, the second elastic band 13 and the rear contact plate 12 and the upper contact plate 14 enhances the fit between the device and the head, ensuring a stable wearing experience while avoiding pressure due to excessive tightness; the ventilation holes on the rear contact plate 12 and the upper contact plate 14 increase air circulation, improve breathability during long-term wear, and reduce stuffiness and discomfort.

[0021] In this embodiment of the disclosure, The rear end face of the seat plate 1 is set as an arc structure, and a contact strip 15 is fixed to the rear end of the seat plate 1. The contact strip 15 is made of memory foam.

A locking bolt 241 is threaded onto the movable seat 24. The locking bolt 241 is pressed against the rail rod 22. Its function is: by rotating the knob 231, the lead screw 23 is driven to rotate. Utilizing the screw 23's helical transmission principle, the movable seat 24 can be driven to move smoothly horizontally on the rail rod 22, which can realize the precise position adjustment of the lighting component in the horizontal direction.

[0023] Example 2, based on Example 1, The cylindrical base 25 is provided with a waist-shaped through groove. A rotating sleeve 252 is rotatably mounted on the cylindrical base 25. The rotating sleeve 252 has a spiral groove inside. A locking ring 251 is installed on the cylindrical base 25. A second locking bolt 2511 is threaded onto the locking ring 251. The second locking bolt 2511 is tightened against the cylindrical base 25. A protruding post 2531 is fixed on the movable cylinder 253. The protruding post 2531 moves in the spiral groove on the rotating sleeve 252. Its function is: when the rotating sleeve 252 is rotated, the protruding post 2531 on the movable cylinder 253 moves along the spiral groove inside the rotating sleeve 252 to adjust the height of components such as the lamp holder 27.

[0024] Example 3, based on Examples 1 and 2, The lamp holder 27 is electrically connected to the connection port on the base plate 1 via a wire. A switch 271 is installed on the lamp holder 27, and a lighting lamp is also installed on the lamp holder 27. The intermediate cylinder 28 is threaded onto the lamp holder 27. The intermediate cylinder 28 has threads. The movable sleeve 29 is threaded onto the intermediate cylinder 28. A pressure ring 292 is installed on the movable sleeve 29 by screws. The pressure ring 292 presses against the lens 291. Its function is to adjust the position of the movable sleeve 29 on the intermediate cylinder 28 by rotating it, thereby adjusting the distance between the lens 291 and the lighting lamp, which facilitates the adjustment of the light focusing effect.

[0025] The working principle of this embodiment is as follows: During use, the tension of the fixing strap 11 is adjusted by adjusting the adhesive tape 111 on the fixing strap 11 according to the user's head size, initially fixing the device to the head. The first elastic band 121, the second elastic band 13, the rear contact plate 12, and the upper contact plate 14 cooperate with each other to further enhance the fit between the device and the head, ensuring a stable fit while avoiding pressure due to excessive tightness. The arc-shaped structure of the rear end face of the seat plate 1 and the memory foam contact strip 15 can conform to the head contour curve. The contact strip 15 can also automatically shape according to the head contour, reducing the device's... The gap between the device and the head prevents wobbling and ensures the device remains stable during inspection. Ventilation holes on the rear contact plate 12 and upper contact plate 14 increase airflow and improve comfort during extended wear. Rotating the knob 231 on the right end of the lead screw 23 rotates the lead screw 23. Due to the helical transmission between the lead screw 23 and the movable seat 24, the rotation of the lead screw 23 drives the movable seat 24 to move smoothly horizontally on the rail 22. Once the movable seat 24 is in the appropriate position, tighten the first locking bolt 241 to press it firmly against the rail 22. The movable base 24 is firmly fixed, thereby enabling precise horizontal position adjustment of the lighting components. When the rotating sleeve 252 is rotated, the protrusion 2531 on the movable cylinder 253 moves along the spiral groove inside the rotating sleeve 252, achieving height adjustment of components such as the lamp holder 27. The flexible metal tube 26 can be freely bent and shaped, allowing for further precise adjustment of the angle and position of the lamp holder 27. Rotating the movable sleeve 29, due to its threaded connection with the intermediate cylinder 28, causes the movable sleeve 29 to move on the intermediate cylinder 28, thereby adjusting the distance between the lens 291 and the lighting lamp. The pressure ring 292 passes through... The screw is installed on the movable sleeve 29 and presses the lens 291 to ensure that the lens 291 remains stable during adjustment. By changing the distance between the lens 291 and the lighting lamp, the focusing effect of the light can be adjusted to meet the lighting needs of different examination scenarios. The rechargeable battery 161 is snapped into the battery compartment 16 and is electrically connected to the lamp holder 27 through the connection port on the base plate 1 via a wire to provide power to the lighting lamp. During the nasal endoscopy examination, the doctor can turn the lighting on or off at any time by operating the switch 271 on the lamp holder 27 as needed, which is simple and convenient to control the lighting status.
