Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically refers to a double eyelid precision positioning device. Background Art

[0002] Double eyelids refer to a shallow groove in the upper eyelid skin above the eyelid margin. When the eyes are opened, the skin below the groove moves upward, while the skin above the groove relaxes and hangs down at the eyelid groove. When performing double eyelid surgery, a double eyelid precision locator is often needed to locate the incision.

[0003] The double eyelid precision locator described in announcement number CN218009980U is provided with an adjustment device, wherein the T-shaped rod can drive the positioning frame to move under the action of the knob, the first bevel gear, the second bevel gear, the threaded rod, the slide groove and the slider, so that the locator can adjust its size according to the face shape of different patients, thereby improving the practicality of the entire locator. However, the prior art still has defects:

[0004] 1. The prior art fixes the card board on the patient's nose by setting a nose bridge groove at the bottom of the card board. However, the nose is an organ protruding from the face and is not easy to be laid flat and fixed. In addition, the prior art cannot adjust the card board according to the different nose shapes of each person, making it difficult to fix the device as a whole on the face. The scope of application is small, which affects the positioning operation.

[0005] 2. In the prior art, knobs are set on both adjustment rods to adjust the size of the T-bar to position the two eyes. This is not only cumbersome to operate, but also difficult to achieve equal movement distances of the two T-bars through manual control, so that the two positioning frames are not symmetrically arranged, affecting the positioning operation. At the same time, the positioning block of the prior art is directly connected to the positioning frame through a push-pull rod, which is prone to loosening, and there is no scale line as a reference, which affects the precise positioning.
