Description

Scleral buckle {SCLERAL DEPRESSOR}

The present invention relates to an ophthalmic scleral buckle used for pressing a sclera.

Detachment of the retina refers to a phenomenon in which the retinal layer is torn, water in the eye leaks, and part or all of the retina falls off the eyeball wall. When the retinal detachment occurs, the defects of the visual field appear, and as the detachment progresses, the area of the visual field defect becomes larger, which is an important cause of blindness if left to stand for a long time. Because of retinal detachment, retinal photoreceptor cells can not obtain nutrients from the choroid. If the exfoliation lasts for a long time, retinal degeneration may occur, resulting in blindness. Currently, the methods used to clinically treat retinal detachment include mainly surgery, laser, freezing, or glaucomatous retinal reattachment, to restore the detached retina, to treat retinal tear, And is intended to be firmly coupled. In the methods for treating retinal detachment, scleral buckling, vitrectomy, and glaucomatous retinal reattachment are needed. Among them, scleral buckling is a method of sticking the retina inside the eyeball by pressing the outside of the eyeball. To this end, it is necessary to align the internal and external positions of the lesion by observing changes in the retina and eyeball while applying pressure to the eyeball from outside the eyeball. The pressing of the sclera is good to predict the state after the scaffold, but it is difficult to mark the exact position of the top of the scaffold. In addition, it is difficult to grasp the relationship between the scleral-retina when the distance between the scleral retina and the sclera is too large due to the detachment of the retinal detachment due to the bullous retinal detachment or the like. The inaccuracies of the position of the pterygium appear to be a failure of the operation, and it is known that about 20% Therefore, there is a need for a method capable of precisely grasping the position of the breast and adhering the retina in the eyeball.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a scleral buckle capable of accurately grasping an inner position and an outer position of retinal detachment.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a screed tapper of the present invention will be described in detail with reference to embodiments and drawings. However, the present invention is not limited to these embodiments and drawings.

A scleral buckle according to an embodiment of the present invention includes a light source provided at one end; And a handle, wherein the light source displays the external position such that the divergent light trans-illuminates the sclera to match the internal and external positions of the lesion on the eye.

The scleral buckle according to an embodiment of the present invention can grasp the position of the scleral flap to accurately match the internal position and the external position of the lesion caused by the retinal detachment and can be very useful for treating retinal detachment. Therefore, it is possible to increase the probability of retinal anatomic adhesion, which is the goal of surgical treatment, through the politics of the scleral buckle.

1 is a cross-sectional view of a scleral buckle according to an embodiment of the present invention. Referring to FIG. 1, a scleral buckle 100 according to an exemplary embodiment of the present invention includes a light source 110, a handle 120, a round part 130, and a control part 140 provided at one end.

1, the light source 110 may be formed in a part of the round part 130. [ The light source 110 represents the external position so that the divergent light is transmitted to the sclera of the patient and is trans-illuminated through the sclera to be utilized for matching the internal position and the external position of the lesion on the eyeball. Therefore, the scleral buckle according to the present invention can grasp the position of the sclera to accurately match the inner position and the outer position of the retinal detachment. Scleral buckling is a very effective way of resolving retinal detachment, but the failure rate of surgery is 20% due to errors in the process of matching the internal and external positions exactly. Therefore, there is a great need for an effective method of matching the external position with the internal position. The present invention provides a method of increasing the accuracy by displaying an external position as a light source.

The light source 110 may include at least one selected from the group consisting of an optical fiber, a light emitting diode (LED), a laser, and a halogen tungsten lamp. In the case of the laser, it can produce light with relatively higher interference when compared to other light sources such as light emitting diodes and lamps. Higher interference allows the emitted light to focus on a small spot size for efficient delivery from the light source, allowing more precise location of the scleral lesion.

The one end of the light source 110 may be covered with a light transmissive transparent or semi-transparent material. The light source 110 can emit light with good transparency or semi-transparency.

2 shows a cross section of a round portion of a scleral buckle according to an embodiment of the present invention. Referring to FIG. 2, one end of the scleral buckle 100 may include a round portion 130 so that the tissue of the patient is not damaged. The light source 110 may be formed under the round portion 130. That is, the light source may be a shape in which a transparent or semi-transparent round member covers the light source. The light source 110 may be formed as a point light source in a part of the round part 130 irrespective of the shape of the round part 130.

The round portion 130 is a portion directly contacting the sclera of the eyeball, and has a curved surface shape so as not to cause physical damage. The round portion 130 may be interchangeable and may be capable of providing various curvatures of various ends through the interchange. As shown in FIG. 2 (a), the round portion 130 may have an elliptical shape that is close to a hemispherical shape, or the round portion 130 may have an elongated elliptical shape Lt; / RTI > In the case of elongated elliptical shape, the location of the lesion can be better represented because the point of pressing is more concentrated, and when the size of the sclera of the patient's eye is small (the size of the sclera is small in children) This small form is preferred. However, if the curvature is too small, the distal end may become too sharp to damage the sclera. Therefore, the curvature of the round portion needs to be provided differently depending on conditions of the patient such as the age of the patient and the size of the eyeball.

However, when the light source 110 formed below the round unit 130 or the round unit 130 is damaged, the round unit 130 may be replaced with the light unit 110, It is possible to suggest a method of solving the problem by replacing the round part 130 or replacing the light source after detachment of the round part and reattaching the round part.

The handle 120 corresponds to the other end of the scleral button 100, and may have a length for increasing gripping feeling and grip feeling. The handle 120 may be made of at least one material selected from the group consisting of stainless steel, titanium, nickel, tantalum, gold, platinum, iridium, carbon, cobalt, carbon, plastic and polymer. As shown in the figure, the handle 120 may have a concave-convex part or a silicone material, not shown in the drawing, to prevent the hand part 120 from slipping when being held by hand.

The handle 120 may include a controller 140 for controlling the light source 110. The control may be performed by turning on or off the light source or adjusting the intensity of the light source, The color of the light source may be switched to white, red, green, blue, or the like, or may include control of a combination thereof. The control unit may be of various types such as a dial type, a button type, and the like, but is not limited thereto.

Figure 3 shows a cross section of the handle of a scleral buckle showing various angles according to an embodiment of the invention. Referring to FIG. 3, one end of the light source 110, including the round portion, has an angle of 50 to 180 with respect to the handle 120, the angle is adjustable, . 3 (a), the angle between the one end of the light source 110 and the handle 120 may be about 100 °, and as shown in FIG. 3 (b) The angle between the one end of the light source 110 and the handle 120 may be about 160 degrees. It is possible to fix the light source 110 at various angles other than the angle formed by one end of the light source 110 and the handle 120. It is necessary to be able to adjust the angle between one end of the light source 110 and the handle 120 according to various conditions of operation and the like and since the angle is changed due to an external force during surgery, It is necessary to be fixed at an angle. The angle between the one end of the light source 110 of the present invention and the handle 120 may be fixed at an acute angle of 90 DEG or less, although it is an exceptional case. . As the scleral buckle 100 is fixed at various angles, it is easier and safer for the user to press the sclera.

Matching the internal and external locations of the scleral lesion may be performed in one step of scleral buckling. Scleral buckling is one of the methods used to treat retinal detachment. It is used to tighten or press the sclera using a silicone band or sponge on the outside of the eyeball to close the torn retinal tear to help the retina settle in its original position. In this case, it is important to apply the pressure to the eyeball from the outside of the eyeball to observe the change of the retina and the eyeball to match the internal position and the external position of the lesion. By using the scleral buckle 100 of the present invention, Light is emitted through the light source 110, and the light source appears to coincide with the outer position and the inner position where the retina of the lesion is peeled off. A silicone band is wrapped around this area to bond the retinal detachment. After the tear of the retina is closed, the liquid that has accumulated under the retina is absorbed and the detached retina is fixed at its original position. Therefore, as a stage of scleral buckling, the scleral buckle 100 of the present invention can be used to grasp the position of the scleral flap to accurately match the internal position and the external position of the retinal detachment, and is very useful for treating retinal detachment Lt; / RTI > Therefore, it is possible to safely treat retinal detachment while minimizing retinal damage.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
