a clinical ophthalmologic operation dilator comprises a supporting plate 1, connecting blocks 2 and sliding grooves 3, wherein an observation port 18 is symmetrically formed in the supporting plate 1, the sliding grooves 3 are symmetrically formed in two sides of the inner wall of the observation port 18, the connecting blocks 2 distributed in a rectangular array are mounted on the outer wall of one side of the supporting plate 1, a movable groove 21 is formed in the connecting block 2, a limiting rod 22 is movably mounted in the movable groove 21, a first elastic belt 13 is arranged on the outer wall of one side of the supporting plate 1, and a buckle 16 is arranged on the outer wall of one end, away from the supporting plate 1;

a second elastic band 14 is arranged on the outer wall of one side, away from the first elastic band 13, of the support plate 1, and a clamping block 17 is arranged on the outer wall of one side, away from the support plate 1, of the second elastic band 14;

the buckle 16 is clamped inside the clamping block 17, so that the first elastic band 13 and the second elastic band 14 are fixedly connected. The clamping force between the clamp 16 and the clamping block 17 ensures that the first elastic band 13 and the second elastic band 14 are fixedly connected to the head of the patient, and the working stability of the support plate 1 is ensured by the elasticity of the first elastic band 13 and the second elastic band 14;

the headrest body 15 is installed to first

elastic band

13 and 14 one side inner walls of second elastic band, and the purpose of lifting patient's head has been reached to the headrest body 15, and the travelling comfort when guaranteeing the patient to perform the operation.

The outer wall symmetry of backup pad 1 one side is installed and is protected and fill up 12, and protection pad 12 is located patient's eye socket department, reaches the purpose of supporting backup pad 1. During the equipment use, medical personnel's manual equipment of taking, and make backup pad 1 be located patient eyes department, two viewing apertures 18 are corresponding with patient's eyes position respectively, medical personnel's manual first elastic band 13 and the second elastic band 14 of taking wind to patient's brain after, and make buckle 16 insert inside the fixture block 17, elasticity through first elastic band 13 and second elasticity, the purpose of fixed support plate 1 has been reached, guarantee backup pad 1 job stabilization nature, and improved patient's use travelling comfort through protection pad 12 and headrest body 15.

Backup pad 1 deviates from 3 one sides outer walls of spout and has seted up standing

groove

11, and 11 inside sunshading boards that are used for placing of standing groove for shelter from the eyes that the patient did not perform the operation, reach the purpose of alleviating patient's intense mood. When the observation port 18 is shielded by the sun shield, the purpose of shielding the eyes of the patient is achieved.

Example two:

the utility model provides a clinical ophthalmic surgery expands and props ware, including backup pad 1, connecting block 2 and spout 3, viewing aperture 18 has been seted up to 1 inside symmetry of backup pad, spout 3 has been seted up to 18 inner wall bilateral symmetry of viewing aperture, 3 inside movable mounting of spout have slider 32, slider 32 one end outer wall is installed and is collected fill 33, collect and fight 33 one side outer wall grafting and install connecting pipe 34, connecting pipe 34 deviates from 35 one side outer walls of collecting vessel and pegs graft and install collecting vessel 35, collecting vessel 35 has reached the purpose of collecting the waste liquid. After the waste liquid flows into the collecting hopper 33, the waste liquid flows into the collecting barrel 35 through the connecting pipe 34, so that medical personnel can collect and treat the waste liquid conveniently;

a spring 31 is arranged on one side of the inner wall of the sliding chute 3, the sliding block 32 is elastically connected with one side of the inner wall of the sliding chute 3 through the spring 31, and the spring 31 pushes elastically to enable the collecting hopper 33 to be in contact with the outer eye angle. The spring 31 is used for forcing the collecting hopper 33 to be in controlled contact with the external canthus, and when waste liquid is generated, the waste liquid generally flows along the external canthus, so that the purpose of collecting the waste liquid is achieved through the collecting hopper 33.

Connecting block 2 that the rectangle array distributes is installed to 1 one side outer wall of backup pad, connecting block 2 is inside to have seted up the movable groove 21, the inside movable mounting of movable groove 21 has gag lever post 22, gag lever post 22 runs through movable groove 21 one side outer wall and installs support arm 23, support arm 23 one side outer wall is installed and is opened eyelid hook 24, it is used for strutting patient's eyelid to open eyelid hook 24, guarantee medical personnel's the operation field of vision, during the use of equipment, it puts in patient eyeball top to open eyelid hook 24, medical personnel manually drive gag lever post 22 and open eyelid hook 24 and take place to remove, thereby reached the purpose of expanding upper and lower eyelid.

Screw hole 25 has been seted up to activity groove 21 inner wall one side, and screw 25 internal thread is connected with screw 26, and screw 26 runs through screw hole 25 one end and contacts with gag lever post 22, has guaranteed gag lever post 22 stable position. When the screw 26 is in contact with the stopper rod 22, the pressing force between the screw 26 and the stopper rod 22 is ensured by the engaging force between the screw 26 and the screw hole 25, so that the stopper rod 22 operates stably.

The working principle is as follows: when the device is used, the medical staff manually takes the device, the support plate 1 is positioned at the eyes of a patient, the two observation ports 18 respectively correspond to the positions of the eyes of the patient, the medical staff manually takes the first elastic belt 13 and the second elastic belt 14 to wind the first elastic belt and the second elastic belt around the brain of the patient, the buckle 16 is inserted into the fixture block 17, the aim of fixing the support plate 1 is achieved through the elasticity of the first elastic band 13 and the second elastic force, the working stability of the support plate 1 is ensured, when the device is used, the eyelid opening hook 24 is placed above the eyeball of the patient, the medical staff manually drives the limiting rod 22 and the eyelid opening hook 24 to move, thereby achieving the purpose of expanding the upper eyelid and the lower eyelid, when the screw 26 is contacted with the limiting rod 22, the pressing force between the screw 26 and the stopper rod 22 is secured by the engaging force between the screw 26 and the screw hole 25, so that the operation stability of the stopper rod 22 is ensured.

The collecting hopper 33 is pushed by the elastic force of the spring 31 to be controlled to contact with the external canthus of the patient, when the patient performs the ophthalmic surgery, the waste liquid such as tears, bloody water and the like generated inside the eyes flows out through the external canthus until the waste liquid flows into the collecting hopper 33, and therefore the purpose of collecting the waste liquid is achieved.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
