Abstract

The invention discloses an eyelid spreader. By the aid of the eyelid spreader, the problem of inconvenience in operation due to the fact that eyelids are manually spread by hands can be solved. The eyelid spreader comprises a mounting cover and two spreading plates, and is characterized in that one end of a driving shaft which is rotationally supported on a side of the mounting cover extends intothe mounting cover and is connected with a driving bevel gear in a non-rotational manner, the other end of the driving shaft is arranged outside the mounting cover, a hand wheel is connected with theother end of the driving shaft, and a non-return mechanism is arranged between the driving shaft and the mounting cover; support seats are connected onto the inner wall of the mounting cover and are positioned on two sides of the driving bevel gear, transmission mechanisms are arranged between the support seats and two sides of the mounting cover and are in transmission connection with the drivingbevel gear, connecting rods are connected onto the transmission mechanisms, two slide grooves are formed in the side wall, which is far away from the driving shaft, of the mounting cover, an end of each connecting rod penetrates the corresponding slide groove to extend out of the mounting cover, and the spreading plates are detachably connected onto the connecting rods by clamping mechanisms in aback-to-back manner. The eyelid spreader has the advantages of convenience in operation and safety in use.

Description

technical field [0001] The present invention relates to devices for ophthalmic surgery, in particular to an eyelid retractor. Background technique [0002] We know that in the treatment and nursing work of ophthalmology patients, no matter the eyes are cleaned or dripped with eye drops, or the eyes are operated, the patient's eyelids need to be stretched. The current way is: the medical workers use their hands to open the patient's eyelids, and then perform liquid medicine titration, cleaning or operation work. Although medical workers can avoid contamination of the patient's eyes by wearing gloves, during the titration of eye drops, cleaning or surgery, the medical staff has been holding the patient's eyelids with their hands, because the hands are too hard , often leads to trembling of the hands, which changes the eyelid opening distance, which is not conducive to the titration of medicine, cleaning or surgery. Contents of the invention [0003] In order to overcome th...
