Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The present utility model will be described in detail with reference to the accompanying drawings.
The present utility model, when embodied, provides an improved ophthalmic eyelid retractor comprising:
An eyelid opening hook 1, wherein a liquid suction part 2 is arranged on the eyelid opening hook 1;
a bracket 9, wherein the bracket 9 is used for installing the eyelid opening hook 1;
The adjusting mechanism is arranged on the bracket 9 and is used for adjusting the stretching or shrinking angles of the two sides of the bracket 9.
Embodiment one:
At least two arch parts 4 are arranged on the eyelid opening hook 1, and the arch parts 4 adopt a circular arc arch structure.
The liquid suction parts 2 comprise at least two liquid suction parts 2 and a drainage tube 3 which are arranged on the eyelid opening hook 1, the eyelid opening hook 1 adopts a hollow structure, one end of the drainage tube 3 is communicated with the liquid suction parts 2, and the other end of the drainage tube passes through the eyelid opening hook 1. The number of the liquid sucking portions 2 may be two or more, and the number and the positions of the liquid sucking holes may be adjusted as needed, and the adjustment of the structure is the scope of the present utility model.
When the liquid suction device is used, a patient lies on the surgical operation, the eyeball position of the patient is higher than the positions of the inner and outer corners of the eye, the liquid suction parts 2 are arranged at positions which are respectively close to the two corners of the eye of the patient, namely the inner corner of the eye and the outer corner of the eye, and the liquid near the inner corner of the eye and the outer corner of the eye is respectively drained to the outside or is drained into the liquid collector through the two liquid suction parts 2, so that residual liquid around the corners of the eye can be effectively removed, the influence on the surgical operation field due to the residual liquid is avoided, and the normal operation of the operation is ensured.
The number of the liquid absorbing parts 2 can be adjusted so that two or more liquid absorbing holes are arranged on the inner corners and two or more liquid absorbing holes are arranged on the outer corners, and the adjustment of the number is the protection scope of the utility model.
Because the heights of the two imbibition holes are inconsistent, the imbibition position is not in direct contact with eyes, and the damage to the tissues in the eyes is avoided.
When the corresponding eyelid opening angle needs to be adjusted, a user can rotate the adjusting knob 8, the adjusting knob 8 drives the adjusting screw 5 to rotate up and down along the support 9, the adjusting screw 5 drives the movable connecting rod 6 to prop up two side plates of the support 9 to the required angle, so that the width of opening the eyelid can be accurately controlled, the flexibility of the structure is high, and the angle can be randomly adjusted according to the requirement.
