DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 5 A retractor for eye plastic surgery comprises a double-claw hook 1, the inner wall of the double-claw hook 1 is rotatably connected to a single-claw hook 2, a connecting part 4 is fixedly installed on one side of the double-claw hook 1, a fixing mechanism 3 is provided on the top of the connecting part 4, and a limiting strip 8 is connected to the bottom of the double-claw hook 1. The fixing mechanism 3 and the limiting strip 8 limit the single-claw hook 2.

[0023] Through the coordinated use of the double-claw hook 1 and the single-claw hook 2, the use state of the retractor can be flexibly converted. The eye's anatomical structure is delicate and complex, and the surgical area is small. Converting to the double-claw state can more accurately clamp and separate fine eye tissues, which is suitable for areas that require delicate operations, such as dealing with double eyelid folds or delicate eyelid edges. Converting to the single-claw state is suitable for surgical steps that require larger-area traction or support, such as the need to expose the surgical field more widely during eye bag surgery.

[0024] Furthermore, the fixing mechanism 3 includes a swivel 301 , a mounting rod 306 is provided inside the swivel 301 , the mounting rod 306 is fixedly connected to the top of the connecting part 4 , an arc strip 302 is provided on the surface of the swivel 301 , and a clamp 303 is provided at one end of the arc strip 302 away from the swivel 301 .

[0025] Furthermore, a handle 5 is fixedly connected to one side of the connecting portion 4 , and a finger sleeve 6 is installed on the top of the handle 5 .

[0026] By changing the shape of the hook body, surgeons can flexibly adjust according to the specific circumstances of the operation, thereby improving the flexibility of surgical operations and the control accuracy of the surgical area, which is very important for ensuring the effect of the operation and reducing tissue damage. In addition, there is no need to frequently replace different types of retractors. A single instrument can meet various surgical needs, reducing the time for instrument exchange during surgery and improving the continuity and efficiency of the surgical process. Double claws and single claws can fit the periocular tissue better, reducing unnecessary traction and compression, thereby reducing the risk of damage to surrounding normal tissues during surgery. The utility model provides a finger sleeve 6, which can facilitate the doctor to use the fingers to hold the retractor. For surgeons, the finger ring design is convenient for the fingers to penetrate and fix. Combined with the variable shape of the hook body, it can reduce hand fatigue during long-term surgery and improve the stability of surgical operations.

[0027] Furthermore, a non-slip rubber pad 7 is fixedly connected to the top of the handle 5 , and a non-slip groove is provided on the top of the non-slip rubber pad 7 .

[0028] The anti-skid rubber pad 7 and the anti-skid groove are used together to facilitate the user to hold the hook through the handle 5 .

[0029] Furthermore, the limiting strip 8 is movably connected to the bottom of the single claw hook 2 .

[0030] Furthermore, a rubber sleeve 305 is installed on the inner wall of the rotating ring 301 , and the rubber sleeve 305 is movably sleeved on the surface of the installation rod 306 .

[0031] By providing the rubber sleeve 305, the damping of the rotation of the rotating ring 301 can be increased to prevent the rotating ring 301 from rotating on its own.

[0032] Furthermore, a plurality of anti-slip protrusions 304 are provided on the surface of the rotating ring 301 .

[0033] The anti-slip protrusion 304 can facilitate the user to rotate the rotating ring 301 .

[0034] Furthermore, the hook heads of the double-claw hook 1 and the single-claw hook 2 have the same shape.

[0035] The hook heads have the same shape, which makes it easy for the double-claw hook 1 and the single-claw hook 2 to pull a large area at the same time.

[0036] When a surgical procedure requiring large-area traction or support is required, the double-claw hook 1 and the single-claw hook 2 are used at the same time, the fixing mechanism 3 limits the top of the single-claw hook 2, and the limiting bar 8 limits the bottom of the single-claw hook 2 to prevent it from rotating inside the double-claw hook 1. When it is necessary to clamp and separate fine eye tissue more accurately, the rubber sleeve 305 and the swivel 301 are rotated on the surface of the mounting rod 306, and the swivel 301 drives the arc strip 302 and the clamp head 303 to rotate so that they are separated from the surface of the single-claw hook 2. The single-claw hook 2 is rotated upward inside the double-claw hook 1 to erect it. After erecting it, the arc strip 302 and the clamp head 303 are reset. The arc strip 302 and the clamp head 303 clamp the single-claw hook 2 to prevent it from rotating downward, so that the doctor can use the double-claw hook 1 alone to operate.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
