Description
Technical Field
The invention belongs to the technical field of vision correction surgical operation equipment, and particularly relates to an interface unit for fixing eyeballs.
Background
Nowadays, the technique of femtosecond laser myopia surgery is rapidly developed, and ensuring the fixation of the eyeballs of a patient in the surgery process is one of key factors for ensuring the precision of the femtosecond laser surgery due to the high positioning precision of the femtosecond laser pulse, short surgery time and the like. The barb-like structure of the fixed eyeball as described in patent US 2001/0021844 A1 causes extreme discomfort to the patient during the operation, and is highly likely to cause the patient to generate stress reaction to cause the operation to fail.
In patent CN110234301a, a docking device is mentioned, which is capable of adsorbing cornea on a platen, but the device has no annular channel, which cannot ensure that eyeballs are uniformly adsorbed on the platen, and even the situation that cornea folds to block a suction channel cannot be avoided, and water accumulation or air accumulation may occur under the platen. In the contact lens disclosed in patent CN101282699B, the cornea is in a non-applanation state, so that the difficulty of laser scanning planning is greatly increased, and the eye is not stressed enough to easily lose adsorption in the surgical process.
The device for docking with the eyeball only considers the eyeball structure, does not consider the shape of the eye, uses circular contact, and is required to always prop open the eyelid of the patient after docking is successful, so that the patient feels uncomfortable to a great extent, and the accuracy of the femtosecond laser operation is affected.
Disclosure of Invention
In response to the shortcomings and improvements of the prior art, the present invention provides an interface unit for fixation of an eye ball that reduces patient discomfort and reduces the likelihood of negative pressure desorption caused by slight head movement during patient surgery.
To achieve the above object, the present invention provides an interface unit for fixing an eyeball, comprising: an interface main body for fixing the eyeball through negative pressure and a transparent body with refraction function; the interface body is in contact with a non-operative area of the cornea, and the transparency is in contact with the operative area of the cornea; the contact area between the bottom of the interface main body and the cornea is an annular curved surface, the annular curved surface is projected into an elliptical ring in the visual axis direction, and the long axis direction of the elliptical ring is the left-right swinging direction of the head of a patient; an annular groove is formed above the annular curved surface, a plurality of supporting structures are arranged in the annular groove, and negative pressure acts on the cornea through the plurality of supporting structures to fix the cornea on the lower surface of the transparent body; an annular platform is arranged above the annular groove and used for placing the transparent body.
Further, the support structure has an angular turn with the cornea contact area to avoid the cornea, the lower surface of the transparency and the annular platform from forming a sealed zone.
Further, the support structure is connected with the upper wall of the annular groove or the lower wall of the annular groove.
Further, a suction channel communicating with the annular groove is provided in the interface body.
Further, the outer wall of the suction channel is of a pagoda structure.
Further, the lower surface of the transparent body is a plane or an aspheric surface with an extension line above the annular groove.
Further, the side wall of the transparent body is frosted or attached with a material capable of absorbing light.
In general, through the above technical solutions conceived by the present invention, the following beneficial effects can be obtained:
(1) The contact area between the bottom of the interface main body and the cornea is an annular curved surface, the shape of an eye ellipse is matched, the long axis direction of projection of the annular curved surface in the visual axis direction is the left-right swinging direction of the head of a patient, the eyeball can be better fixed on a negative pressure structure by the design, and the head is not easy to separate from negative pressure even if the patient shakes left and right slightly in the operation process. The curvature of the annular curved surface is similar to that of the cornea, and the cornea can be naturally attached to the patient interface. After the eyeballs are butted, even the open eye clamp can be taken down, so that the upper eyelid and the lower eyelid of a patient are naturally attached to the lower edge of the interface main body shell, and the discomfort of the patient is relieved.
(2) The supporting structure and the cornea contact area are provided with angle turning so as to avoid water accumulation in a closed area formed by the cornea, the lower surface of the transparent body and the annular platform; because the accumulated water caused by the closed area can not be effectively discharged through the suction channel, the design of the invention can ensure that the scanning track is positioned in the cornea instead of the accumulated water when the laser is used for processing the cornea, thereby further improving the precision of the laser processing and the success rate of the operation.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
In the present invention, the terms "first," "second," and the like in the description and in the drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
The present embodiment provides an interface unit for fixing an eyeball, as shown in fig. 1, including: the interface main body 1 for fixing the eyeball through negative pressure and the transparent body 2 with refraction function can be made of photosensitive resin, acrylic and medical materials, and the transparent body 2 can also be a glass body with high light transmission capacity. The interface unit can shape the cornea surface, make the cornea fit with the lower surface of the transparent body, fix the cornea position, and is favorable for positioning the reference point of laser ophthalmic surgery and cutting the cornea.
Taking an aspherical transparent body as an example, fig. 2 to 4 show detailed structures of the interface unit.
The interface body 1 includes a suction channel 102 and an annular groove 104. The reinforcing rib structure 101 is arranged between the suction channel 102 and the shell of the interface main body 1, so that the connection between the suction channel 102 and the shell of the interface main body 1 is more stable, and the suction channel 102 is not easy to break in practical application. The annular groove 104 is in communication with the suction channel 102, and a support structure 105 is provided in the annular groove 104, which support structure 105 is connected to only one of the annular groove upper wall 104a and the annular groove lower wall 104b, which may be alternately connected, with a groove gap 106 between the support structure 105 and the annular groove lower surface, but does not constitute a suction-like shape. The negative pressure acts on the cornea 3 through a plurality of support structures 105 to secure the cornea 3 to the lower surface 23 of the transparency.
The support structure is angularly turned with respect to the cornea interface 108; the annular platform 109 contacted with the lower surface 23 of the transparent body has a certain thickness, and the supporting structure and the cornea contact surface 108 have angle turning, so that the generation of accumulated water 24 caused by a sealed region formed by the cornea 3, the lower surface 23 of the transparent body and the annular platform 109 with a certain thickness can be avoided, thus ensuring that a scanning track is positioned in the cornea instead of the accumulated water 24 when the laser processes the cornea 3, and ensuring the precision of laser processing and the success rate of operation.
The contact area between the bottom of the interface body 1 and the cornea 3 is an annular curved surface 111, and the surface of the eye which is actually in contact with the air is an ellipsoid, and the ellipse is also an ellipse when seen in the visual axis direction, and the major axis of the ellipse is consistent with the left-right swing direction of the head of the patient due to the eyelid of the human. Therefore, the interface unit of the invention can be easier and firmer when absorbing eyes, the head is slightly moved in the operation process of a patient, the negative pressure desorption is not easy to be caused, and the patient is comfortable. The eyeball stress area of the patient is an annular curved surface outside the operation area. The eye clip can be removed even when the eyeballs are in butt joint, so that the upper eyelid and the lower eyelid of the patient can be attached to the lower edge of the patient interface shell naturally.
It should be noted that the present invention is applicable when the eyeball structure is a sphere or an ellipsoid. Taking a sphere as an example, the annular curved surface described in the invention can be understood as a curved surface obtained by cutting the upper half part of the spherical surface by using two circular arc curved surfaces, wherein the curved surface has a shape similar to the top edge of a gold ingot; as shown in fig. 4, in the perspective schematic view of the interface unit, the bottom edge 110 of the interface body is a circular arc with two low ends and a high middle. Taking an ellipsoid as an example, an ellipse with a major axis in the x-axis and a minor axis in the y-axis rotates around the x-axis for one circle, and the formed three-dimensional figure is the ellipsoid, and the surface of the three-dimensional figure is the ellipsoid. The annular curved surface described in the present invention is understood to be a curved surface obtained by intercepting an ellipsoid by using an xy coordinate plane and a plane parallel to the xy coordinate plane, and in this case, in the perspective schematic view of the interface unit, the bottom edge 110 of the interface main body is a straight line. Of course, it is also possible to intercept the upper half of the ellipsoid with two circular arc curved surfaces to obtain a circular curved surface having a shape resembling the top edge of a shoe-shaped gold ingot. In other words, the invention can be realized as long as the projection of the truncated annular curved surface in the visual axis direction is an elliptical ring.
Fig. 5 and 6 show a transparent structure, wherein a transparent body 2 is connected with an interface main body 1 through a glue adhesion or sealing ring, the transparent body 2 divides the interface main body 1 into an upper space and a lower space, the upper space is used for fixing the whole body of the interface main body 1, and the lower space is used for fixing eyeballs of a patient. The upper surface 21 of the transparent body is planar, the lower surface 23 of the transparent body is planar or aspherical, and when the lower surface of the transparent body is aspherical, the equivalent radius of curvature is slightly similar to but slightly larger than the radius of curvature of the front surface of the cornea. After the negative pressure is turned on, the cornea is adsorbed to the lower surface 23 of the transparency, the transparency 2 is brought into contact with the cornea 3 and the imaginary extension 25 of the lower surface of the transparency is above the annular groove 104. The transparent body side 22 is frosted or attached with a material capable of absorbing light; after the negative pressure is turned on, the cornea 3 is adsorbed to the lower surface 23 of the transparent body, and the two are adhered to each other. In the surgical procedure, a path is planned and laser ablation is performed with the contact surface between the cornea 3 and the lower surface 23 of the transparent body as a reference surface. The transparent body 2 has a certain refraction effect and can change the converging state of the converging light beams.
Fig. 7 and 8 show the interface unit in contact with the cornea 3 of the patient, the cornea 3 to be laser processed is fully contacted with the lower surface 23 of the transparent body, and the part of the contact surface 108 between the supporting structure and the cornea is truly contacted with the cornea 3, so that the accumulated water or air generated in the cornea adsorption process can be smoothly discharged through the suction channel under the condition that the cornea is not easy to deform, thereby reducing the risk of operation failure.
Fig. 9 shows an enlarged view of a portion of the annular recess 104 and the support structure 105; fig. 10 is a schematic diagram showing that the air accumulation or the water accumulation 24 can be avoided after the cornea 3 of the patient is adsorbed, the water accumulation 24 can be sucked out through the supporting gaps 107 among the supporting structures 105, the supporting structures and the cornea contact surface 108 have curve or fold-line angle change, the surface with continuous and slow angle change is the best like a round angle, the curvature of the supporting structures and the cornea contact surface 108 is the best close to the curvature of the cornea, and the comfort of the eyeball fixing process of the patient can be greatly improved. In practical application, the interface unit similar to the cornea curvature can be customized according to parameters such as the cornea curvature measured before operation. Bubbles can appear in the cornea during laser processing, and after the upper surface of the cornea is cut, the bubbles can be sucked out like the ponding 24, so that the occurrence of damage to an unprocessed area caused by excessive bubble collection in cornea tissue can be reduced.
Fig. 11 is a schematic view of the visual axis direction interface unit acting on the eyes of the patient, because the eyelid 31 is elliptical, the surgical area to be performed is at the center of the ellipse, that is, the center of the cornea 3, and then the bottom edge 110 of the interface body of the eyeball is fixed to be naturally contacted with the eyes during the surgical procedure, and even if the open eye clamp is removed, the upper eyelid and the lower eyelid of the patient can be naturally attached to the bottom edge 110 of the interface body, thereby greatly improving the comfort level of the patient and facilitating the successful operation.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
