Eye speculum with flat plate structure

Abstract

The invention discloses a eyelid opener with a flat plate structure, which comprises a flat base, an operation window is formed by an opening in the middle of the flat base, a pair of hooks are symmetrically arranged on the sides of the operation window, and the connecting end of the hook is connected to the rack. Fixed connection, the hook is inserted into the flat base through the rack and connected with the flat base, the flat base is provided with an adjustment knob, the adjustment button is used to adjust the relative distance between the two hooks, the bottom of the flat base passes through The adhesive is bonded to the skin around the eyes. By setting the eyelid speculum as a flat plate, during the operation, the eyelid speculum is glued to the skin around the eyes, and the adjustment knob is used to adjust the opening of the hook to open the eyelid, realizing one-handed operation, and the eyelid speculum is fixed Finally, it is not necessary to use one hand to stabilize the eyelid speculum, which liberates the operator's hands, overcomes the problem that the traditional eyelid speculum requires two hands to operate, and facilitates the operation.

Description

technical field [0001] The invention relates to the field of eye surgery instruments, in particular to a lid opener with a flat plate structure. Background technique [0002] The eyelid speculum is a special medical device for the ophthalmology department of the hospital. It is used to expand the eyelid (the two tissues above and below the eye when the eyelid is used), and most of them are used for ophthalmic surgery. Generally, the eyelid opener is a screw-type rotary eyelid opener, and its operation method is: hook the eyelid with the hook of the eyelid opener, then screw it into the screw, and turn the two ends of the eyelid opener (that is, the clamp arm in this application) outward Dilation, the eyelids are widened. It can be seen that the traditional eyelid opener requires two-handed operation, that is, one hand needs to hold the eyelid opener to stabilize its position, and the other hand needs to rotate the screw to expand the eyelids.

Problems solved by technology

It can be seen that the traditional eyelid opener requires two-handed operation, that is, one hand needs to hold the eyelid opener to stabilize its position, and the other hand needs to rotate the screw to expand the eyelids. It seems quite troublesome, especially in ophthalmic surgery, when the general surgeon does not need the help of the assistant operator, in order to expand the surgical field of view, he has to temporarily abandon the ongoing operation to operate the eyelid opener. This kind of pause in the middle of the operation is likely to lead to surgical accidents, which is not conducive to the smooth operation of the chief surgeon. When the assistant operator operates the eyelid opener, due to the narrow position of the eye and limited space, it is undoubtedly necessary for two people to operate the eye. It increases the difficulty of the operation and is likely to cause surgical accidents. Therefore, the traditional eyelid speculum that needs to be operated by both hands has the problem of inconvenient use
