Abstract
The utility model belongs to the operation instrument of ophthalmology which is used to cure the eye muscle choroid insertion operation of the denaturalization pigment of retina. The upper and lower parts of a knife handle are crosswise hold, and the end appears clamp-mouth type and is nipped with a tailor-made blade. The middle of the knife handle is provided with a groove and is connected with a spring blade. The trail end of the knife handle is provided with a sleeve whose inner is provided with a spring sleeve and a cuniform clip for positioning. The eye muscle choroid insertion operation knife has the advantages of small volume, strong elasticity and toughness, clean separating sclera level, being easy to peel off, sharp-edged knife blade, accurate falling point and better effect on testing operation.
Description
This utility model belongs to the operating theater instruments for the treatment of eyes, is exclusively used in the eye muscle choroid and attaches operation.
Current, still there is not effective treatment way for the ophthalmology retina pigment denaturation both at home and abroad.My institute has initiated the eye muscle choroid and has attached operation in order to treat this difficult and complicated illness, and this art belongs to international initiative, and effective percentage is up to more than 90%, and the required apparatus required precision of this operation height, is that existing medical apparatus and instruments institute is inaccessiable.
This utility model is in order to solve that the eye muscle choroid attaches the specific (special) requirements of operation and a kind of special-purpose operating theater instruments that designs has the degree of accuracy height, and toughness elasticity is strong, and the characteristics that point of a knife is sharp have been filled up a blank of medical apparatus and instruments.
This utility model is by cutter hub, and blade (3) and spring leaf (5) three parts are formed.Cutter hub is made of last handle of a knife (1), following handle of a knife (2), sleeve pipe (4), and it is shaft-like that upper and lower handle of a knife is semicircle, is a whole cylinder when closing up.The front end of upper and lower handle of a knife is the jaw shape, both intersect and connect with pin (8) at infall, groove is opened at the handle of a knife middle part, the tail end of following handle of a knife (2) has a wedge-shaped card (9), the tail end of last handle of a knife (1) is connected with the foot piece (10) of rear end band screw, and the stairstepping through hole is opened in the inside of sleeve pipe (4), and the through hole first half is enclosed within on the foot piece (10), latter half ofly put into the screw rod (7) that bar portion is with spring (6), screw rod (7) and foot piece (10) are for being threaded.Blade (3) is the stalloy of parallelogram, and the angle of blade and hypotenuse is 40 °～80 °, folds up the front end jaw place at upper and lower handle of a knife.Spring leaf (5) is the perforates and open the oblique sheet of groove respectively of two flush ends, and wherein the upper end tapping is fixedlyed connected with last handle of a knife groove, and the interior bearing pin (11) of bottom groove and following handle of a knife groove is slidingly connected.When upper and lower handle of a knife closes up, move after sleeve (4) is stressed, located by wedge-shaped card (9).
According to the operation needs, the blade of blade (3) and the angle of hypotenuse are good with 45 ° or 60 °, and blade width is 1.5～5mm.
For guaranteeing that blade folds up firmly, the front end jaw contact surface of upper and lower handle of a knife makes scalelike mark or striated plane.
The utlity model has following advantage:
1, volume is little, does not influence surgical field of view during operation.
2, blade good springiness, toughness are strong, and it is clear to separate the sclera level, is easy to peel off suprachoroid scleral tissue, and don't the easy damaged choroid.
3, point of a knife is sharp, accurate placement, and draw materials conveniently.
