As shown in fig. 1, the utility model provides an axial position marking device before ophthalmic surgery, include:
a lens sliding rod 1, both ends of the lens sliding rod 1 are connected to the two support posts 21 of the eye support bracket 2;
a first spectacle frame 3, the first spectacle frame 3 is connected in a sliding way 11 of the lens sliding rod 1
The second spectacle frame 4 is connected in the slide way 11 of the lens slide rod 1 in a sliding way, and the second spectacle frame 4 is positioned at the rear side of the first spectacle frame 3; the second frame 4 includes a base frame 41, a rotation driving section 42, a rotation frame 43, and a pressing section; the base frame 41 is provided with a rotation driving part 42, and the rotation driving part 42 drives the rotation frame 43 to rotate; the rotating frame 43 is fixedly provided with a lens structure 431, and a pressing part which can move up and down is arranged in the lens structure 431; the pressing portion has a cavity 442, and two ink markers 444 are disposed under the pressing portion, and both ink markers 444 are communicated with the cavity 442.
The utility model realizes the positioning of the first picture frame 3 to the human eyes by fixing the lens sliding rod 1 on the eye supporting bracket 2 matched with the existing slit lamp; and in order to make the eyeball more clearly seen, the first lens frame 3 and the second lens frame 4 are separated; when the eyeball does not need to be marked, the eyeball is observed only through the first lens frame 3; when the eyeball needs to be marked, the second spectacle frame 4 is moved to the first spectacle frame 3, so that the two spectacle frames are overlapped; finally, the doctor can make the ink marker 444 complete the marking work on the eyeball at the same time by pressing down the pressing portion.
In order to enable the first lens frame 3 and the second lens frame 4 to be on the front and rear sides, and both the first lens frame 3 and the second lens frame 4 are slidable; now, a slide rail 11 is provided at the lower side of the lens sliding rod 1, the slide rail 11 includes two parallel slide rails, i.e. a first slide rail 111 and a second slide rail 112, the first slide rail 111 is located at the front side of the second slide rail 112; the upper side of the first frame 3 is slidably connected to the second slide rail 112 through a slider, and the upper side of the second frame 4 is slidably connected to the first slide rail 111 through a slider.
In order to enable the rotation of the rotating frame 43; the rotation driving unit 42 is now a rotary rod, and the rotary rod is connected with a gear 421, and the gear 421 is embedded on the base frame 41. By rotating the rotating rod, the gear 421 is rotated; to rotate in cooperation with the gear 421 and to enable the rotating frame 43 to rotate; now, an annular rack is provided on the bottom surface of the rotating frame 43, and the annular rack is engaged with the gear 421.
In order to realize that the pressing part can return to the initial position after marking the eyeball; the pressing part comprises a pressing sheet 441 and a cavity 442; a cavity 442 is arranged below the pressing sheet 441; a through hole 432 is provided in the middle of the lens structure 431; the cavity 442 is slidably connected to the through hole 432; a plurality of elastic members 443 are circumferentially arranged below the pressing piece 441, and the lower end of each elastic member 443 is connected to the lens structure 431. Specifically, the elastic member 443 may be a disc spring, so that when the pressing piece 441 is pressed down, and the user releases the force applied to the pressing piece 441, the elastic member 443 returns the pressing portion.
To enable simultaneous marking on both sides of the eyeball, the ink marker 444 is now provided in a structure extending from top to bottom outward from the center of the lens structure 431; and ink marker 444 is a hollow needle tube to allow ink to flow from chamber portion 442 into ink marker 444, and the particular structure of the tip of ink marker 444 mimics the marker pen structure to allow ink to mark the surface of the eyeball at the tip of ink marker 444.
Since ink marker 444 is located below lens structure 431; in order to avoid the doctor being difficult to see the ink marker 444, the ink marker 444 cannot coincide with the light emitted by the slit lamp; two marking lines 432 are now provided on the upper surface of the lens structure 431, each marking line 432 corresponding to the direction of extension of the ink marker 444.
To clearly show the degree of rotation of the rotating frame 43; the second spectacle frame 4 also comprises an outer frame 45, and a base frame 41 is fixedly arranged on the inner ring at the lower end of the outer frame 45; the inner ring at the upper end of the outer frame 45 is rotatably connected with a rotating frame 43; the upper end face of the outer frame 45 is marked with a circle of scales. Thus, when the rotation driving portion 42 drives the rotating frame 43 to rotate, the lens structure 431 rotates along with the rotating frame 43; at this time, the indication line 432 points to the scale on the outer frame 45 after rotating, and the scale reads the degree of rotation of the rotating frame 43, which is convenient for the doctor to rotate and adjust the rotating frame 43.
To enable labeling of the eyeball, methylene blue is now provided within the cavity portion 442; because the methylene blue has no toxicity, the low-dose use of the methylene blue can not cause damage to eyes, and simultaneously has a certain dyeing effect, thereby obviously marking the mark points on the eyes.
In order to be able to adjust the height of the first frame 3; now, two ends of the lens sliding rod 1 are respectively provided with a hoop 12; each clamp 12 is connected to the same side post 21; specifically, the doctor adjusts the height of the lens slide bar 1 by adjusting the vertical position of the clip 12 on the support 21.
In addition to the above embodiments, the application method of the present invention is as follows:
the patient sets the affected eye at the first frame 3, and the doctor generates a strip light at the eyeball through the slit lamp to mark the position needing surgery with the light; subsequently, the doctor makes the second lens frame 4 and the first lens frame 1 coincide by moving the second lens frame 4; at this time, the doctor can rotate the rotating frame 43 by the angle obtained by rotating the strip light by the slit lamp, so that the two ink markers 444 on the rotating frame 43 are overlapped with the strip light, and the two ink markers 444 are then just positioned on the strip light at the two points marked by the eyeball. The doctor finally presses the pressing portion, thereby lightly contacting the two ink markers 444 with the surface of the eyeball to form two ink marker points.
In summary, the utility model realizes the switching between marking and non-marking of the eyeball through the separation of the first frame 3 and the second frame 4, and avoids the observation of the whole eyeball of the affected eye (due to the shielding of the pressing part) when the second frame 4 is directly overlapped with the second frame 3; the utility model realizes the alignment and the coincidence of the ink marker 444 to the strip light (emitted by the slit lamp) on the eyeball through the rotating frame 43 of the second spectacle frame 4; the utility model discloses a splenium of setting realizes carrying out the mark at both ends through two ink mark spare 444 to the eyeball according to the splenium.
Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
