Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an adjustable blue or green light aqueous humor drainage device for eye, including plastic sheet 1, the four corners department of plastic sheet 1 sets up for the arc, a plurality of screw hole has been seted up at plastic sheet 1's top, the size of a plurality of screw hole is all inequality, and the size that is located the circular trompil of bottom is the biggest, the inner chamber spiro union that is located the left side and is close to top department screw hole has the second to press gasbag 3, the top that gasbag 3 was pressed to the second sets up for the arc, and the arc that gasbag 3 was pressed to the second sets up opening down, the left side that gasbag 3 was pressed to the second is close to top department and pegs graft and has second drainage tube 6, there is drainage dish 9 in the left side of plastic sheet 1 near top department, the cross section of drainage dish 9 sets up for the arc, and drainage dish 9's arc sets up opening towards the front side, drainage dish 9's front side is equipped with second drainage hole 8, the left end of second drainage tube 6 runs through drainage dish 9 right side and runs through the setting each other with second drainage hole 8, the left side of drainage dish 9 is close to the edge and presses down with the first drainage hole 10 of second drainage dish 10, the left side of the first drainage dish of the left side of drawing and the first drainage dish 9 of drawing 5, the left side of the third drainage tube 10 that the left side of drawing is close to press down and the first drainage dish 5 the first drainage tube of the first drainage of the left side of the second drainage tube and the second drainage tube 5, the left side of drawing 5 of drawing and the left side of drawing and the second drainage tube 10 first drainage dish of drawing the left side of drawing and the second drainage dish of drawing the left side of drawing 5 of drawing and the left side of drawing and the second drainage tube 10.

s1: taking a patient in a supine position, after surface anesthesia, conventionally disinfecting and paving a towel, diluting an iodophor solution to wash eyes after eyelid operation, and inserting a drainage disk 9 below a scleral flap;

s2: then the first drainage tube 5, the second drainage tube 6 and the third drainage tube 10 which are adjacent and the first pressing air bag 2, the second pressing air bag 3 and the third pressing air bag 4 which are corresponding to the left end are arranged under the conjunctival sac;

s3: after reaching the corneal limbus, the second drainage hole 8 and the anterior chamber are mutually attached and aligned, and the second pressing air bag 3, the third pressing air bag 4 and the first pressing air bag 2 which are pressed are released after being inserted into the anterior chamber, so that aqueous humor is drained and absorbed through the first drainage hole 7 and the second drainage hole 8;

s4: because impurities often exist in the aqueous humor to block a pipeline, the forced drainage and absorption can cause that the drainage cannot be successfully carried out and the eyes are injured, if the second drainage tube 6 is blocked, the corresponding second pressing air bag 3 is pressed, the blockage is sprayed out by air pushing, and other air bags are loosened to absorb the blockage through the drainage holes;

s5: the eyelids are stretched, the tops of the outer first pressing air bag 2, the second pressing air bag 3 and the third pressing air bag 4 are rotated to be opened through the action among threads, and the drained substances are treated, and after the operation is finished, the tobramycin and dexamethasone eye ointment is applied to the eyes.

The working principle is as follows: the patient takes a supine position, after surface anesthesia, a conventional disinfection drape is used, after an eye is operated, the iodophor solution is diluted to wash the eye after eyelid opening, the drainage disk 9 is inserted below a scleral flap, the adjacent first drainage tube 5, second drainage tube 6 and third drainage tube 10 and the corresponding first pressing air bag 2, second pressing air bag 3 and third pressing air bag 4 at the left end are placed under the conjunctival sac, the second drainage hole 8 and the anterior chamber are mutually attached and aligned after reaching the corneal limbus, the pressed second pressing air bag 3, third pressing air bag 4 and first pressing air bag 2 are released after the anterior chamber is inserted, so that aqueous humor is drained and absorbed through the first drainage hole 7 and the second drainage hole 8, because impurity often can exist and block up the pipeline when in the aqueous humor, drainage and absorption can lead to failing to successfully drain and can cause the eye injury simultaneously by force, if take place under the circumstances of jam at second drainage tube 6, press corresponding second and press gasbag 3, make through gaseous promotion and spout the plug and absorb it through relaxing other gasbags through the drainage hole simultaneously, strut the eyelid, will outer first press gasbag 2, the second is pressed gasbag 3 and the third and is pressed the top rotation of gasbag 4 and open it through the effect between the screw thread, and it can to handle the material of drainage play, the operation finishes, tobramycin dexamethasone eye ointment coating operation eye.
