Description

Technical Field

[0001] This utility model belongs to the field of ophthalmic surgery technology, specifically relating to a forehead and chin support frame for patients in the prone position of the fundus. Background Technology

[0002] The cornea, iris, and lens at the front of the eyeball are defined by ophthalmologists as the anterior segment, while the vitreous humor, retina, and choroid at the back are defined as the posterior segment. The bottom of the posterior segment is called the fundus. The fundus consists of the retina, retinal blood vessels, optic nerve head, optic nerve fibers, the macula on the retina, and the choroid behind the retina. Diseases in these areas are collectively called fundus diseases. The main harm of fundus diseases is to vision; in severe cases, they can lead to blindness. Fundus diseases are numerous, with complex causes and variable symptoms. Early symptoms of peripheral fundus diseases often go unnoticed by patients. By the time patients experience vision loss, the disease may already be quite advanced. However, lesions in the central areas of the fundus, such as the macula and optic nerve, can significantly affect vision.

[0003] When patients undergo treatment for fundus diseases, they often need to maintain a prone position, requiring facial support to prevent pressure on the eyes. Common support devices typically support the forehead and chin. However, in practice, because the patient's face is downward, it is inconvenient for medical staff to observe the patient's eyes, affecting the treatment process. Furthermore, some forehead-chin supports can obstruct the patient's eyes, further hindering observation. Therefore, a forehead-chin support frame for prone fundus patients is needed to address these issues. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a forehead-chin support frame for patients in the prone position, which is characterized by easy observation, easy adjustment, and strong practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forehead-chin support frame for a prone fundus patient, comprising a fixed plate, guide rods symmetrically fixed on one side of the top of the fixed plate, a shielding pad fixed to the top of one end of the guide rod, a first support pad fixed to one side of the shielding pad, an adjusting plate movably sleeved on the outer side of the other end of the guide rod, symmetrically provided moving openings on the side wall of the adjusting plate, the guide rod passing through the moving openings, a second support pad fixed to the top of the adjusting plate, both the first and second support pads being made of elastic material, a spring rod fixedly connected to the middle of the side wall of the fixed plate, an observation plate movably sleeved on the outer side of the spring rod, a mirror surface provided on the top surface of the observation plate, a through hole provided in the middle of the observation plate, and the spring rod passing through the through hole.

[0008] As a preferred technical solution of the forehead-chin support frame for a prone position of a fundus patient according to this utility model, the bottom of the adjustment groove is connected to a second threaded hole, and the inner side of the second threaded hole is connected to a second bolt.

[0009] As a preferred technical solution of the forehead-chin support frame for a prone position of a fundus patient according to the present invention, one end of the elastic rod is fixed with a stop block, the stop block is located on one side of the observation plate, and the width of the stop block is larger than the diameter of the through hole.

[0010] As a preferred technical solution of the forehead and chin support frame for a prone position of a fundus patient according to the present invention, the shielding pad is made of elastic material, and the height of the shielding pad is higher than the height of the first support pad.

[0011] As a preferred technical solution of the forehead-chin support frame for a prone position of a fundus patient according to this utility model, the side wall edge of the fixing plate is fixed with fixing screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, this invention, through the guide rod, first support pad, adjustment plate, and second support pad, allows for easy operation when treating patients with fundus diseases. After the patient is in a prone position, the guide rod is fixed to one side of the bed via a fixing plate. The first support pad is fixed to the top of one end of the guide rod, and the adjustment plate is sleeved on the top of the other end. The patient can support their chin on the first support pad and their forehead on the second support pad on top of the adjustment plate, thus supporting the patient's face and preventing pressure on the eyes. Simultaneously, the adjustment plate can move on the guide rod, allowing medical staff to adjust the distance between the first and second support pads according to the patient's facial dimensions, making it suitable for patients of different body types. After adjustment, tightening the first bolt on the adjustment plate secures the plate.

[0014] Furthermore, by symmetrically setting positioning frames on both sides of the adjustment plate, the U-shaped adjustment rod of the positioning frame is inserted into the inner side of the adjustment plate, and the clamping pad at the other end of the U-shaped adjustment rod is located on the second support pad. When the patient's forehead is supported by the second support pad, medical staff can move the U-shaped adjustment rod so that the clamping pad clamps and supports the patient's forehead. After the clamping is stable, tighten the second bolt to tighten and fix the U-shaped adjustment rod, thereby improving the stability of the patient's head placement. At the same time, it can be flexibly adjusted according to the size of the patient's head.

[0015] In addition, by setting a spring rod on the side wall of the fixed plate, an observation plate is movably sleeved on the spring rod. The observation plate can rotate on the spring rod and can also drive the spring rod to bend. A mirror is set on the top surface of the observation plate. When the patient is lying face down, the mirror is facing the patient's face. Medical staff can adjust the angle of the mirror to easily observe the patient's eyes from multiple angles, avoiding the situation in conventional surgery where the patient's face orientation makes it inconvenient for medical staff to observe. This improves the practicality of the overall support tool. Furthermore, the first and second support pads are located above the two guide rods. When the patient is lying face down, the eyes are located between the guide rods, further facilitating medical staff to observe through the mirror. Attached Figure Description
