Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Figures 1 and 2, a kind of micro- shape corneal ablation device of ophthalmologic operation is provided in the utility model embodiment, it should Cutter includes main body 100 and bandage 200, and 200 both ends of bandage are connected to the left and right two of 100 operating surface of main body End, the main body 100 is fixed on patients head, the operating surface is the face patient and to trouble when in use of main body 100 The side of person's progress corneal ablation.In the present embodiment, the quantity of the bandage 200 is two, is separately mounted to the operation The upper and lower ends in face, and an adjusting buckle 210 is all had on each bandage 200, to adjust the corresponding bandage 200 Length.The quantity of certain bandage 200 can be one or three or more quantity, and bandage 200 can also be replaced For elastic band, as long as can achieve the effect that main body 100 being fixed on patients head.

The operating surface of the main body 100 is the curved surface being bonded with human body face, can install one layer of rubber on the operating surface Pad or foam-rubber cushion, fit closely the face of patient with the operating surface and promote wear comfort.

Referring to Fig. 3 and Fig. 4, the position that the inside of the main body 100 corresponds to patient's eyes offers an inner cavity respectively 110, each inner cavity 110 offers opening 111 on the operating surface.One is all had in each inner cavity 110 Mounting base 120, the mounting base 120 is movably arranged in the inner cavity 110 by multiple push rods 130, and the mounting base 120 Always in the space in 111 faces of the opening.In the present embodiment, the quantity of the push rod 130 is three, described in three One end of push rod 130 is rotatably installed on the side wall of the mounting base 120, and the other end is rotatably installed in the inner cavity 110 Inner wall on, three push rods 130 and the tie point of inner cavity 110 are located on the trisection point of 110 contour of inner cavity, three The push rod 130 and the tie point of mounting base 120 also are located on the trisection point of 120 contour of mounting base, and described in three The specification of push rod 130 is identical, and under the control unit control of each push rod 130, push rod 130 is elongated or shortened, by institute State position and angle that mounting base 120 is pushed to needs.

Certainly, the quantity of the push rod 130 can be four or more quantity, and the quantity of the push rod 130 is more, then More accurate for the control of 120 position of mounting base, the minimum number of the push rod 130 then needs three.

The mounting base 120 has laser head 121 and multiple LED light 122 on the side wall towards the operating surface, described Laser head 121 is located at the center of 120 side wall of mounting base, during the laser head 121 is centered around by multiple LED light 122 Centre.

The mounting base 120 is rotatably installed in the inner cavity 110 by connecting rod 140 back on the side wall of the operating surface Back on the side wall of the operating surface, described 140 one end of connecting rod is vertically fixed on the center of 120 side wall of mounting base, separately One end is rotatably installed on the side wall of the inner cavity 110.Under the promotion of the push rod 130, the mounting base 120 is at certain angle Spending in range is being radius with the connecting rod 140, using the tie point of the connecting rod 140 and inner cavity 110 as the spherical surface of the centre of sphere Upper rotation is adjusted the position of the laser head 121 with this, is cut by laser to the cornea of patient.

Referring to Fig. 5, the connecting rod 140 has bulb 141, the inner cavity 110 in the one end connecting with the inner cavity 110 Side wall on there is ball seat 150, the outer diameter of the bulb 141 is suitable with the internal diameter of the ball seat 150, the bulb 141 insertion It can be rotated in any direction in the ball seat 150 after into the ball seat 150.The connection of the push rod 130 and inner cavity 110 The connection type of mode and the push rod 130 and mounting base 120 can be using turn of above-mentioned connecting rod 140 and inner cavity 110 Dynamic connection type.Certainly rotation connection mode mentioned above can also use other modes, for example, by using universal joint or lead to The fit system for crossing bulb and ball slot can achieve the effect of universal rotational.

Main body 100 when in use, is worn on the position of patient facial region Yu eyes face by the cutter, and passes through bandage Main body 100 is fixed on patients head by 200, after connecting the power supply of laser head 121 and LED light 122, is controlled respectively by computer The retracted position of each push rod 130 is made, to control the motion path of laser head 121 in mounting base 120, is completed with this to patient's eye The cutting work of cornea.

Disclosed above is only several specific embodiments of the utility model, and still, the utility model embodiment is not office It is limited to this, the changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
