Description

Technical Field

[0001] This utility model relates to medical device technology, and in particular to a special table and chair for positioning after vitrectomy. Background Technology

[0002] Vitrectomy is a common surgical procedure for treating serious fundus diseases such as retinal detachment, vitreous hemorrhage, and diabetic retinopathy. Proper postoperative recovery directly affects the surgical outcome and visual prognosis.

[0003] When sitting, lean forward, bringing your chin as close to your chest as possible (similar to looking down at your navel), so that your face is perpendicular or nearly perpendicular to the ground (at an angle of no less than 45°). You can place a soft cushion on the table and gently rest your forehead on it to reduce neck fatigue; or use a special "head-down support" to help maintain your posture. It is strictly forbidden to tilt your head back or look straight ahead (such as looking up at the ceiling or keeping your back straight), otherwise air may shift and affect retinal repositioning.

[0004] Placing a soft cushion and gently resting the forehead on it is not suitable for patients of different heights because the height of the table and chair is fixed, which may cause discomfort for the patient. Utility Model Content

[0005] The purpose of this invention is to overcome the existing defects and provide a special table and chair for postoperative positioning after vitrectomy, which can adapt to patients of different heights and improve their sitting comfort.

[0006] The technical solution to achieve the above objective is: a special table and chair for postoperative positioning after vitrectomy, including a rehabilitation table body, an adjustable seat body placed near the rehabilitation table body, and two guide rails mirror-mounted on the tabletop of the rehabilitation table body by multiple screws, with a rotating adjustment component for supporting the patient's forehead slidably connected on each guide rail.

[0007] Preferably, the rotation adjustment assembly includes two sliding blocks, a first support plate, a fixing bolt, two support blocks, a rotating shaft, a fixing nut, an electric push rod bracket, an electric push rod, a second support plate, and a limiting block. Each of the guide rails has a sliding block slidably connected to it. The upper surfaces of both sliding blocks are connected to the first support plate. A threaded hole is formed in the middle of the first support plate, and the fixing bolt is detachably connected to the threaded hole. The fixing bolt is in close contact with the tabletop of the rehabilitation table body. Two support blocks are mirror-imaged on the upper surface of the first support plate. The rotating shaft passes through each of the two support blocks. One end of the rotating shaft has the limiting block, and the other end has an external thread. The limiting block is in close contact with the corresponding support block. The fixing nut is installed at the threaded part of the rotating shaft, and the fixing nut is in close contact with the corresponding support block. The middle part of the rotating shaft is connected to the electric push rod bracket, which has a fixed end for the electric push rod. The telescopic end of the electric push rod is connected to the second support plate.

[0008] Preferably, the upper surface of the second support plate is provided with the soft pad.

[0009] Preferably, the bottom surface of the fixing bolt is provided with an anti-slip coating.

[0010] Preferably, a washer is tightly attached between the fixing nut and the corresponding support block.

[0011] The beneficial effects of this utility model are: by rotating the fixing bolt, the first support plate can be moved freely along the guide rail direction, thereby adjusting the straight distance between the second support plate and the patient. The tilt angle of the second support plate can be adjusted by adjusting the angle of the rotating shaft. The distance between the second support plate and the patient's forehead can be finely adjusted by the electric push rod. This method can adapt to patients of different heights and improve their comfort when sitting. Attached Figure Description

[0014] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown, a special table and chair for positioning after vitrectomy includes a rehabilitation table body 1, an adjustable seat body 2, two guide rails 3, and a rotation adjustment component.

[0017] Specifically, an adjustable seat body 2 is placed near the rehabilitation table body 1. Two guide rails 3 are mirror-mounted on the tabletop of the rehabilitation table body 1 by multiple screws. Each guide rail 3 is slidably connected to a rotating adjustment component for supporting the patient's forehead.

[0018] Specifically, the rotation adjustment assembly includes two sliding blocks 4, a first support plate 5, a fixing bolt 6, two support blocks 7, a rotating shaft 8, a fixing nut 9, an electric push rod bracket 10, an electric push rod 11, a second support plate 12, and a limiting block 13. Each guide rail 3 has a sliding block 4 slidably connected to it. The upper surfaces of both sliding blocks 4 are connected to the first support plate 5. A threaded hole is formed in the middle of the first support plate 5, and a fixing bolt 6 is detachably connected to the threaded hole. The fixing bolt 6 is in close contact with the tabletop of the rehabilitation table body 1. The upper surface of the first support plate 5 is mirror-like. The device has two support blocks 7, and a rotating shaft 8 passes through each of the two support blocks 7. One end of the rotating shaft 8 is provided with a limiting block 13, and the other end of the rotating shaft 8 is provided with an external thread. The limiting block 13 is in close contact with the corresponding support block 7. A fixing nut 9 is installed at the thread of the rotating shaft 8, and the fixing nut 9 is in close contact with the corresponding support block 7. An electric push rod bracket 10 is connected to the middle part of the rotating shaft 8. The electric push rod bracket 10 is provided with a fixed end of an electric push rod 11. The telescopic end of the electric push rod 11 is connected to a second support plate 12, which serves to support the patient's forehead.

[0019] Specifically, the upper surface of the second support plate 12 is provided with a soft pad, which can provide cushioning for the patient's forehead and improve comfort; the bottom surface of the fixing bolt 6 is provided with an anti-slip coating, which can increase the friction between the fixing bolt 6 and the tabletop of the rehabilitation table body 1, ensuring the stability of the first support plate 5; a washer is tightly attached between the fixing nut 9 and the corresponding support block 7, which can increase the friction between the fixing nut 9 and the corresponding support block 7, thereby ensuring that the rotating shaft 8 is firmly fixed to the two support blocks 7.

[0020] Working principle: After vitrectomy, when adjusting this device, first rotate the fixing bolt 6 to move it away from the tabletop of the rehabilitation table body 1. At this time, the first support plate 5 can be moved freely along the guide rail 3 until it is in the appropriate position. Then, rotate the fixing bolt 6 in the opposite direction to fix the first support plate 5. Then, loosen the fixing nut 9 to freely adjust the angle of the rotating shaft 8, which can adjust the tilt angle of the second support plate 12. Then, the height of the second support plate 12 from the rotating shaft 8 can be freely adjusted by the electric push rod 11, which can accommodate patients of different heights and improve the comfort when sitting.
