Description

Technical Field

[0001] The utility model relates to the technical field of retina treatment, and particularly relates to a light therapy device for retina treatment. Background Technique

[0002] Fundus diseases are common and frequently-occurring diseases in ophthalmology, with a wide variety of categories and a high incidence rate. Laser treatment of fundus diseases has remarkable curative effects. Even for some fundus diseases, laser treatment has become the first choice. It integrates three wavelengths of lasers, yellow light, red light, and green light, and can instantaneously switch among the three wavelengths of red, green, and yellow lasers without time lag. It can meet the laser treatment of various fundus diseases and has the characteristics of simplicity, rapidity, minimally invasive, and effectiveness. Due to the characteristics of lasers, such as coherence, monochromaticity, and high intensity, which are different from visible light, when performing light therapy on the retina, it can precisely change the intraocular tissue structure to achieve the purpose of treatment.

[0003] In the existing patent application with the application number CN202121326137.8, a light therapy device for retina treatment is proposed. When performing treatment, the patient's head is placed on the head fixing device, the adjusting and fixing strap at the bottom is slid to the lower jaw, and fixed with a fixing knob. Then, the adjusting and fixing strap at the top is slid to the forehead for fixation. Then, the eye auxiliary frame is placed on the eye to perform light therapy, which can fix the patient's head. However, due to the lack of components for binding the patient's head, the stability of this fixing method is poor. When the patient uses it, the patient's head will have a horizontal shaking phenomenon, which will affect the treatment effect. Therefore, it needs to be improved. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a phototherapy device for retinal treatment includes a device base 1. At the rear end of the device base 1, two L-shaped support frames 2 are symmetrically and fixedly installed. A head limiting component 3 is movably sleeved on the two L-shaped support frames 2. The head limiting component 3 consists of a sleeve 12 and an elastic strap 22. The elastic strap 22 is fixedly installed on the outer walls of the two sleeves 12. A fixing component 4 is fixedly installed on the sleeve 12. The fixing component 4 consists of a U-shaped frame 15, a moving block 16, a spring 17, and a first insertion rod 18.

The first insertion rod 18 is fixedly installed at the inner end of the moving block 16. A tightening component 5 is fixedly installed on the elastic strap 22. The tightening component 5 consists of a U-shaped elastic plate 19 and a second insertion rod 21. The second insertion rod 21 is fixedly installed on the inner wall of the U-shaped elastic plate 19. A phototherapy instrument main body 6 is fixedly installed at the upper end of the device base 1. A phototherapy head 7 is fixedly installed at the rear end of the phototherapy instrument main body 6. A lower jaw support 8 and a forehead limiting member 10 are fixedly sleeved on the two L-shaped support frames 2, and the forehead limiting member 10 is located above the lower jaw support 8. A lower jaw support plate 9 is fixedly installed at the upper end of the lower jaw support 8. A number of blind holes 11 are longitudinally and evenly formed on the L-shaped support frame 2. When a patient is undergoing treatment, the lower jaw can be placed on the lower jaw support plate 9, and the forehead can be pressed against the forehead limiting member 10. Then, the elastic strap 22 on the head limiting component 3 is sleeved around the patient's head, and then the tightening component 5 is used to tie together the excess length of the elastic strap 22, thereby fixing the patient's head. When it is necessary to adjust the height of the head limiting component 3, the fixing of the head limiting component 3 to the L-shaped support frame 2 can be released by using the fixing component 4 first, and then the head limiting component 3 can be moved on the L-shaped support frame 2. When the height of the head limiting component 3 is appropriate, the fixing component 4 is used to fix the head limiting component 3 on the L-shaped support frame 2. When the patient's head is effectively fixed, the patient can undergo treatment through the phototherapy instrument main body 6 and the phototherapy head 7.

[0021] By providing a head limiting component 3 on the two L-shaped support frames 2, when a patient is undergoing treatment and places the lower jaw on the lower jaw support plate 9 and presses the forehead against the forehead limiting member 10, the head limiting component 3 is further used to tie and fix the patient's head, so that the patient's head can be effectively limited and fixed, thereby reducing the phenomenon that the patient's head shakes horizontally during treatment, and ultimately ensuring the treatment effect. By providing a tightening component 5 on the elastic strap 22, the elastic strap 22 can be adjusted, enabling the head limiting component 3 to fix patients with different head circumferences, thereby improving the practicality of the head limiting component 3. By providing a fixing component 4, the fixing and release of the head limiting component 3 can be facilitated, thereby facilitating the up and down movement adjustment of the head limiting component 3.

[0022] Specifically, the head limiting component 3 is located between the chin supporting component 8 and the forehead limiting component 10, the sleeve 12 is movably sleeved on the L-shaped supporting frame 2, a through hole 13 is provided on the sleeve 12, and the through hole 13 penetrates the sleeve 12 inside and outside, and a plurality of insertion holes 14 are evenly provided on the elastic bandage 22 in the horizontal direction, the U-shaped elastic plate 19 on the fastening member 5 is sleeved on the stacked elastic bandage 22, and a receiving hole 20 is provided on one side wall of the U-shaped elastic plate 19, and the second insertion rod 21 passes through the two insertion holes 14 provided on the elastic bandage 22 and is inserted into the receiving hole 20, when the head limiting component 3 moves on the L-shaped supporting frame 2, the sleeve 12 will slide up or down on the L-shaped supporting frame 2; after the elastic bandage 22 is tied to the patient's head, the method of using the fastening member 5 to tie the excess elastic bandage 22 together is as follows: first, the excess elastic bandage 22 is tied as follows: Figure 1 , Figure 2 The U-shaped elastic plate 19 on the fastening member 5 is then opened outward, and then the U-shaped elastic plate 19 is placed on the folded portion of the elastic band 22, and finally the U-shaped elastic plate 19 is loosened, so that the second insertion rod 21 passes through the two insertion holes 14 on the elastic band 22 and is inserted into the receiving hole 20 under the elastic force of the U-shaped elastic plate 19, and finally presents as shown in FIG. Figure 1 In the state shown, the tightening member 5 is about to tie together the redundant elastic bands 22. In this state, the elastic bands 22 can firmly fix the patient's head.

[0023] Specifically, the U-shaped frame 15 on the fixing component 4 is fixedly installed on the outer wall of the sleeve 12, and the first plug rod 18 is inserted into the blind hole 11 after passing through the through hole 13 inwardly. When it is necessary to release the fixation of the head limit assembly 3, the moving block 16 and the first plug rod 18 can be pulled outward, so that the first plug rod 18 is moved out of the blind hole 11. At this time, the spring 17 will be compressed by the moving block 16. When the first plug rod 18 is completely moved out of the blind hole 11, the fixation of the head limit assembly 3 is released; when it is necessary to fix the head limit assembly 3, the moving block 16 can be loosened, so that the first plug rod 18 is inserted into the blind hole 11 under the elastic force of the spring 17, and the head limit assembly 3 is fixed.
