Description

Technical Field

[0001] The utility model relates to the field of optical lenses, in particular to a medical fluoroscopic optical lens. Background Technique

[0002] Optical glass is made by mixing oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melting at high temperature in a platinum crucible, stirring evenly with ultrasonic waves to remove air bubbles, and then cooling slowly for a long time to prevent internal stress in the glass block. The cooled glass block must be measured by an optical instrument to check whether the purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. The qualified glass block is heated and forged into a blank of an optical lens.

[0003] Now, optical lenses are key components playing an important role in the medical field. For example, in X-ray fluoroscopy equipment, high-quality medical fluoroscopic optical lenses can accurately transmit and focus X-rays, enabling doctors to obtain clear images and thus make accurate diagnoses.

Detailed implementation mode

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and the implementation mode.

[0028] First embodiment

[0029] Please refer to in conjunction with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 Schematic structural diagram of the first embodiment of a medical fluoroscopic optical lens provided by the present utility model; Figure 2 is Figure 1 Schematic structural diagram of the protective ring shown; Figure 3 is Figure 1 Schematic cross-sectional structural diagram of the protective ring shown; Figure 4 is Figure 2 Schematic enlarged view of part A shown; Figure 5 is Figure 3 Schematic enlarged view of part B shown. A medical fluoroscopic optical lens includes:

[0030] Two protective rings 1, a lens 2 is arranged inside the protective ring 1, and fixing holes 5 are opened inside the protective ring 1;

[0031] A plurality of limiting grooves 3 are all arranged inside the protective ring 1, and limiting blocks 4 are all slidably connected inside the plurality of limiting grooves 3;

[0032] A fixing groove 6 is arranged inside the protective ring 1. A fixing pin 61 is slidably connected inside the fixing groove 6. One end of the fixing pin 61 and inside the fixing groove 6 is provided with a fixing spring 62. A moving groove 63 is opened inside the fixing pin 61. A moving block 64 is slidably connected inside the moving groove 63. One end of the moving block 64 is fixedly connected with a moving handle 65.

[0033] The top of the moving block 64 is arc-shaped. When the moving handle 65 is pressed, when the moving block 64 moves to one side inside the moving groove 63, the fixing pin 61 is squeezed to move upward along the arc surface of the moving block 64. When the fixing pin 61 moves downward, the moving block 64 is squeezed to move to one side, so that the moving handle 65 is reset.

[0034] The plurality of limiting grooves 3 are all opened inside the protective ring 1, and the tops of the plurality of limiting blocks 4 are all fixedly connected to the bottom of another protective ring 1.

[0035] The plurality of limiting blocks 4 are used for limiting between the two protective rings 1 to prevent separation between the two protective rings 1.

[0036] The fixing groove 6 is opened inside the protective ring 1, and one end of the fixing pin 61 is slidably connected inside the fixing hole 5.

[0037] Two reset grooves 7 are opened inside the protective ring 1, and reset blocks 71 are all slidably connected inside the two reset grooves 7.

[0038] One ends of the two reset blocks 71 and respectively inside the two reset grooves 7 are both provided with reset springs 72.

[0039] One sides of the two reset blocks 71 are respectively fixedly connected to the top and bottom of the moving handle 65. After the moving handle 65 is released, the two reset springs 72 respectively push the two reset blocks 71 to move to one side inside the two reset grooves 7, so that the moving handle 65 is reset, thereby assisting in pushing the moving handle 65 to reset.

[0040] The working principle of a medical fluoroscopy optical lens provided by the present utility model is as follows:

[0041] During use, by pressing the movable handle 65 to one side, the movable block 64 is driven to move to one side inside the moving groove 63. As a result, while the fixing pin 61 moves upward inside the fixing groove 6, the fixing spring 62 is compressed. When the fixing pin 61 separates from the fixing hole 5, the protective ring 1 is rotated to one side, thereby driving the plurality of limiting blocks 4 to move to one side inside the plurality of limiting grooves 3 to appropriate positions. After separating the two protective rings 1, the plurality of limiting blocks 4 are driven to separate from the plurality of limiting grooves 3.

[0042] Place the lens 2 inside the protective ring 1. After merging the protective ring 1 with another protective ring 1 and rotating it to one side, the plurality of limiting blocks 4 are driven to move to one side inside the limiting groove 3 to appropriate positions. After releasing the movable handle 65, the fixing spring 62 pushes the fixing pin 61 to move to one side inside the fixing groove 6 and enter the inside of the fixing hole 5.

[0043] Compared with the related art, a medical fluoroscopy optical lens provided by the present utility model has the following beneficial effects:

[0044] The present utility model provides a medical fluoroscopy optical lens. After merging the two protective rings 1 and rotating them to appropriate positions to one side, the plurality of limiting blocks 4 move to appropriate positions to one side inside the plurality of limiting grooves 3 respectively. While limiting the separation between the two protective rings 1, the fixing pin 61 enters the inside of the fixing hole 5, thereby preventing the protective ring 1 from rotating to one side, increasing the stability when the two protective rings 1 are fixed, preventing the two protective rings 1 from separating, and enhancing the fixing effect.
