Specific embodiment
Now in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, invention is further explained, a kind of corneal astigmatism axis with level meter
The front end of position marker, including operation handle 1, the operation handle 1 is equipped with axis of astigmatism instrument 2, the axis of astigmatism instrument 2
Including outer ring 21 and inner ring 22, the 21 attended operation handle 1 of outer ring is provided with the scale of annular on the outer ring 21,
It is interval that long scale, which is 30 degree, and it is interval that middle scale, which is 10 degree, and it is interval that short scale, which is 2 degree,.Top is counted since 0 degree of right side,
90 degree of top, left side 180 degree；Lower section is counted since 0 degree of left side, 90 degree of lower section, right side 180 degree, wherein 0 He of the left and right sides
180 degree scale is overlapped.The upper surface of the inner ring 22 is equipped with axle position graduation mark 23, represents the axle position of astigmatism.Described is interior
Ring 22 is entrenched in the inside of outer ring 21, and the inner ring 22 can rotate relative to 21360 degree of outer ring and have certain damping.It is described
The inside of outer ring 21 be equipped with annular groove 25, the outside of the inner ring 22 is equipped with the annular protrusion 26 being adapted to annular groove 25,
The inner ring 22 is realized by the sliding cooperation of annular protrusion 26 and annular groove 25 and is rotated relative to outer ring 21.The inner ring 22
Bottom be connected with cornea marker, the cornea marker is two symmetrically arranged serrated knife blades 24, described in two
Serrated knife blade 24 is collinearly symmetricly set on the circumference of inner ring 22, and the axle position of the serrated knife blade 24 and 22 upper surface of inner ring is carved
Spend the alignment setting of line 23.Two blades point-blank arrange, and with the axle position graduation mark above inner ring in approximately the same plane
Upper close alignment, the i.e. direction of blade represent axis of astigmatism direction, and the adjustment of any axle position is carried out by stirring positioning ridge.
Connecting rod 11 is additionally provided between the operation handle 1 and outer ring 21, the connecting rod 11 is connect with outer ring 21
One end before be arranged obliquely, it is such bending design is conducive to label have certain eye socket depth cornea.
The lower edge of the outer ring 21 is to cater to the radian of eyeball to carry out the high outside and low outside bevelled junction of good fixation
Structure.
The cutting edge of the serrated knife blade 24 is arc, the high outside and low outside setting of the cutting edge.In order to cater to the song of cornea
Rate, blade are in certain radian, outer high interior ground, and scratch corneal epithelium under certain application pressure and form label.
There are two the positioning ridge 27 of symmetrically arranged protrusion, the positioning ridge 27 drives interior for the top of the inner ring 22
The adjustment to 22 axle position of inner ring is realized in the rotation of ring 22, and the adjustment of axle position is carried out for stirring inner ring.
At 90 degree of angles between the positioning ridge 27 and axle position graduation mark 23.
The center of the operation handle 1 is additionally provided with air-bubble level 12, is marking for testing correction astigmatism marker
When in horizontal position bubble be directed at central graduation mark, to avoid deviation.
The end of the operation handle 1 is additionally provided with the skid resistance strip 13 for increasing hand-held frictional force.
Application method of the present invention: patient's normotopia is sat up straight, and head-up front, eye speculum struts palpebra inferior after dripping surface anaesthetic
Exposure cornea.Before label, adjusted in axis of astigmatism, that is, rotates blade to corresponding scale according to measurement result by positioning ridge,
Label pigment (such as methylenum careuleum or skin marking pen pigment) is smeared in serrated knife blade.In order to avoid the bridge of the nose and eye socket to block as far as possible
Influence to astigmatism label, when which marks for right eye (R), handle is placed in left side, using top
Dial carry out axle position adjustment and label；When for left eye (L) label, handle is placed in right side, using the dial (hand of lower section
