Description

Technical Field

[0001] The invention relates to a mobile treatment frame for ophthalmic care. Background Art

[0002] Ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous and retinal diseases, optometry, glaucoma and optic neuropathy, cataracts and other eye diseases. Ophthalmology is a department that diagnoses and treats the eyes, which are composed of the eyeball and its auxiliary structures. The eyeball is the main part of the visual organ, and it has two functions: refraction and imaging and photosensitivity. The auxiliary parts of the eye include the eyelids, conjunctiva, lacrimal apparatus, eye muscles, and orbital fascia and fat, which protect, move and support the eyeball. The perfection of the structures of various parts of the eye is of great significance for the eye to complete its visual function.

[0003] During ophthalmic care treatment, the patient's head needs to be fixed to facilitate eye surgery, fumigation and other care treatments, but the patient's hands are generally not fixed. During eye care treatment, the patient may shake his arms unconsciously due to tension, pain and other stimuli. The shaking or trembling of the arms will cause the head to move, resulting in displacement between the eyes and the treatment instrument, affecting the patient's eye care treatment and even damaging the patient's eyes.

[0120] When in use, the lifting cylinder 91 can drive the reinforcing plate 92 to move, thereby driving the inclined support 93 to move. At this time, the height of the support platform 1 and the hand fixing assembly 7 can be adjusted.

[0121] The angle adjustment assembly 12 includes a rotating platform 121, a lifting cylinder 91 is installed on the top of the rotating platform 121, and the side of the rotating platform 121 is slidably connected with a limit ring 122;

[0122] The cross section of the limiting ring 122 is a T-shaped structure, and the limiting ring 122 is fixedly connected to the inner wall of the supporting base 10;

[0123] A plurality of supporting balls 123 are rotatably connected to the inner wall of the supporting base 10 , and a sliding groove is provided on the bottom surface of the rotating platform 121 , through which the supporting balls 123 are slidably connected to the bottom surface of the rotating platform 121 .

[0124] In the present technical solution, the angle of the support platform 1 and the head fixing component 2 can be adjusted by using the angle adjustment component 12 .

[0125] When in use, the rotating table 121 can be rotated with the support of the limiting ring 122 and the supporting ball 123, so as to adjust the angle of the supporting table 1 and the hand fixing assembly 7, so that the treatment frame is more flexible when in use.

[0126] The stabilization component 13 includes a protective shell 135, and the protective shell 135 is connected to both sides of the support base 10. A two-axis motor 136 is installed at the bottom of the support base 10. The two output ends of the two-axis motor 136 are connected to a transmission shaft 137, and the end of the transmission shaft 137 away from the two-axis motor 136 is connected to the central gear 133;

[0127] The central gear 133 is arranged in the inner cavity of the protective shell 135, and both sides of the central gear 133 are meshedly connected with adjustment racks 138. A limiting groove is provided on one side of the adjustment rack 138, and a limiting strip 139 is provided in the limiting groove. The limiting strip 139 is connected to the inner wall of the protective shell 135;

[0128] An arc rack plate 131 is connected to the top of one of the adjustment racks 138, and an annular rack plate 132 is arranged below the arc rack plate 131. The arc rack plate 131 and the annular rack plate 132 are engaged with each other, and the annular rack plate 132 is installed on the top of the support base 10 and the rotating table 121;

[0129] The bottom of another adjusting rack 138 is connected to an anti-skid plate 134 , and the anti-skid plate 134 is provided with anti-skid stripes on its surface.

[0130] In the present technical solution, the stabilizing component 13 can be used to lock and contact-lock the rotating table 121 and the anti-slip plate 134, that is, the arc rack plate 131 is away from the annular rack plate 132, and the anti-slip plate 134 is close to the ground. When the rotating table 121 cannot rotate, the arc rack plate 131 is engaged with the annular rack plate 132 to prohibit the rotating table 121 from rotating. At this time, the anti-slip plate 134 is away from the ground, so that the treatment frame can be moved using the sliding wheel 11.

[0131] When in use, the two-axis motor 136 can drive the transmission shaft 137 to rotate, thereby driving the center gear 133 to rotate. When the center gear 133 rotates, it can drive the adjustment racks 138 on both sides to move toward or away from each other along the limit strip 139, thereby driving the arc rack plate 131 and the anti-slip plate 134 to move. That is, when the treatment frame needs to be moved, the anti-slip plate 134 is away from the ground, and the arc rack plate 131 and the annular rack plate 132 are tightly attached to the rotating table 121 to limit the rotating table 121. When the treatment frame moves, the rotating table 121 cannot move, making the treatment frame more stable when moving. When it does not need to move, the anti-slip plate 134 is close to the ground, making the treatment frame more stable, and the arc rack plate 131 is away from the annular rack plate 132, and the rotating table 121 can rotate.
