DETAILED DESCRIPTION

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example 1

[0024] The eye surgery eyelid opening device described in this embodiment is as follows: Figure 1 As shown, the face opener body includes a clamping arm 1 and a fixing block 2. A support assembly for preventing the face opener body from falling directly from the patient's eye is vertically arranged at the bottom of the fixing block 2, so as to support the face opener body, thereby preventing the face opener body from falling directly from the patient's eye after the operator slips and collides with the face opener body, which is convenient for ensuring the normal operation and improving the efficiency, and also convenient for reducing the damage to the patient;

[0025] The face opener body is a face opener commonly used in existing eye surgeries. The working principle of the face opener is similar to the retractor used in surgical operations. It supports the eyelids and facilitates operators to treat the patient's eyes. Face openers usually include two types: press-open and close types and rotation-open and close types. The face opener body in the present application can adopt either of the two opening and closing methods. When in use, it can also be directly installed on the existing face opener by welding or gluing, thereby improving its stability and applicability while reducing the cost of use.

[0026] Example 2

[0027] This embodiment further illustrates the technology. Figure 1 and Figure 2 As shown, the support component includes a support plate 4, a support block 5 that fits the patient's nose is arranged at the bottom of the support plate 4, an adjustment component 3 for adjusting its support height is arranged between the top of the support plate 4 and the fixed block 2, and a buffer component for increasing the patient's comfort is arranged between the support plate 4 and the support block 5, which is convenient for improving the stability of the face opener while also facilitating improving the applicability and the patient's comfort.

[0028] like Figure 1 and Figure 2 As shown, the adjustment component 3 includes a vertically arranged first connecting rod 3.3, the top of the first connecting rod 3.3 is connected to the bottom of the fixed block 2, the bottom of the first connecting rod 3.3 is sleeved with an adjustment tube 3.4 threadedly matched with it, the bottom of the adjusting tube 3.4 is penetrated by a second connecting rod 3.5 threadedly matched with it, and the bottom of the second connecting rod 3.5 located on the outside of the adjusting tube 3.4 is connected to the top of the support plate 4, so that the adjustment tube 3.4 can be rotated according to needs to quickly adjust the support height, thereby improving its applicability and improving surgical efficiency.

[0029] Two clamping blocks 3.1 are arranged between the top of the first connecting rod 3.3 and the fixed block 2, and the clamping blocks 3.1 are vertically fixed to the bottom of the fixed block 2. First through holes communicating with each other on the left and right are opened on the clamping blocks 3.1 and the first connecting rod 3.3. Bolts 3.2 are installed in the first through holes to make the first connecting rod 3.3 swing back and forth, so as to adjust the support angle according to needs, thereby making it more applicable and comfortable.

[0030] The top of the first connecting rod 3.3 is in interference fit with the two clamping blocks 3.1, which makes it easy for the first connecting rod 3.3 to swing back and forth through the bolt 3.2 to adjust its supporting angle. After the adjustment is completed, the first connecting rod 3.3 and the clamping blocks 3.1 are in a relatively fixed state, making its supporting effect better and more stable.

[0031] The thread direction of the second connecting rod 3.5 is opposite to that of the first connecting rod 3.3, so that the adjustment tube 3.4 can be rotated to drive the first connecting rod 3.3 and the second connecting rod 3.5 to rotate at the same time, so that the adjustment speed is faster;

[0032] When in use, because the first connecting rod 3.3 cannot rotate, when the adjusting tube 3.4 is rotated, the adjusting tube 3.4 and the second connecting rod 3.5 will be driven to rotate downward at the same time, thereby achieving the same effect of quickly adjusting the support height.

[0033] The support plate 4 and the second connecting rod 3.5 are freely rotatable in the horizontal direction, which is convenient for increasing its applicability, making its operation faster and more convenient, reducing the time for adjusting the support block 5 and improving the efficiency of surgery;

[0034] The second connecting rod 3.5 and the support plate 4 can be freely rotated through a bearing connection. A mounting groove for mounting the bearing is opened on the top of the support plate 4, and the outer ring of the bearing is fixed in the mounting groove. Then the bottom of the second connecting rod 3.5 is inserted into the bearing and fixed to it.

[0035] like Figure 2 and Figure 3 As shown, the buffer assembly includes at least two vertically arranged guide rods 8, a second through hole is opened on the support plate 4 for the guide rod 8 to pass through, a baffle is fixed on the guide rod 8 above the second through hole for preventing it from falling off, a first spring 7 is mounted on the guide rod 8 between the baffle and the support plate 4, and the two ends of the first spring 7 are respectively fixed to the baffle and the top of the support plate 4, so as to buffer the face opener body when it is subjected to downward pressure, thereby reducing its swing amplitude and reducing damage and discomfort to the patient's nose.

[0036] A second spring 6 is provided between the support block 5 and the support plate 4 to prevent the support block 5 from directly contacting and colliding with the support plate 4 during buffering, thereby preventing the support block 5 from causing damage and discomfort to the patient's nose.

[0037] The support block 5 is an overall arc-shaped structure, and an arc-shaped groove for fitting with the support block 5 is opened at the bottom of the support plate 4, which is convenient for increasing the fit between the support block 5 and the patient's nose to make it have a better fixing effect, and also facilitates a higher fit between the support block 5 and the support plate 4, making it more stable when performing buffering.

[0038] The left and right ends of the support block 5 are fixed with limit blocks 9 for preventing it from falling off the patient's nose, so as to increase the fixing effect between the support block 5 and the patient's nose and avoid the support block 5 falling off the patient's nose, which not only affects the supporting effect but also easily causes damage to the patient.

[0039] The limiting block 9 is made of silicone material and has an overall hemispherical structure, which is convenient for improving the fit between the supporting block 5 and the patient's nose, thereby improving the fixing effect, making the fixation more stable, and also convenient for improving the patient's comfort.

[0040] During use, if Figure 1 and Figure 2 As shown, first rotate the adjusting tube 3.4 to adjust to the required support height according to the needs and the specific conditions of the patient, then rotate the adjusting tube 3.4 in the opposite direction to shorten it, and then use the face opener body to open the patient's eyes, align the supporting block 5 with the patient's nose, and then rotate the adjusting tube 3.4 forward to extend it, so that the supporting block 5 fits tightly against the patient's nose. Before the supporting block 5 fits tightly against the patient's nose, its supporting angle can be swung back and forth according to needs.
