Description

Technology Field

[0001] The present invention relates to an eye disc. Background Technology

[0002] Ocular surgery refers to surgery on the eye or its appendages performed by an ophthalmologist. The eye is a vulnerable organ, requiring extreme caution before and after surgery.

[0003] During eye surgery, a speculum is used to separate the upper and lower eyelids. This speculum may have two metal bars inserted into the center of the eye to separate the upper and lower eyelids, respectively.

[0004] However, conventional eye discs had a problem in that corneal damage occurred because the two metal bars came into contact with or compressed the cornea of ​​the eye during the process of being inserted into the inner side of the upper and lower eyelids and then withdrawn.

[0005] Furthermore, in conventional eyelid expanders, when the two metal bars supported on the upper and lower eyelids move in a direction that spreads them apart, the direction of movement of the two metal bars is parallel to the face, causing the metal bar spreading the upper eyelid to press against the frontal bone. As a result, the levator palpebrae superioris muscle is crushed and damaged by the metal bar spreading the upper eyelid against the frontal bone, leading to the problem of ptosis.

[0006] Here, ptosis is a condition in which the upper eyelid descends and covers the eyeball; as the upper eyelid covers the eyeball, it is aesthetically unpleasing, and in severe cases, it can obstruct the visual axis of the eyeball, potentially leading to decreased vision.

[0007] In addition, existing eyelid openers had a problem in which, when the two metal bars supported on the upper and lower eyelids moved in the direction of spreading them apart, the direction of movement of the two metal bars became parallel to the face, causing the two metal bars to detach from the upper and lower eyelids.

[0024] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the present invention, and the present invention is defined only by the scope of the claims.

[0025] Unless otherwise defined, all terms used herein (including technical and scientific terms) may be used in a meaning commonly understood by those skilled in the art to which the present invention pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0026] Prior to describing the present invention, in various embodiments, components having the same configuration are denoted by the same reference numerals and are described representatively in the first embodiment, while in other embodiments, configurations different from the first embodiment are described.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0028] FIG. 1 is a perspective view showing an eye opening device according to a first embodiment of the present invention, FIG. 2 is a perspective view showing a first hinge part and a first locking part (a second hinge part and a second locking part) of an eye opening device according to a first embodiment of the present invention, and FIG. 3 is a perspective view showing an eye opening device according to a first embodiment of the present invention in a state where the upper eyelid and the lower eyelid are opened.

[0029] As illustrated in FIGS. 1 to 3, the eye examination device according to the first embodiment of the present invention may include a frame (10), a first rotational arm (20), a second rotational arm (30), a moving part (40), a first support arm (50), and a second support arm (60).

[0030] The frame (10) is the basic body of the present invention. A first rotational arm (20) and a second rotational arm (30) can be rotatably connected to both sides of the frame (10).

[0031] The first rotational arm (20) can be rotatably coupled to one side of the frame (10), and the second rotational arm (30) can be rotatably coupled to the other side of the frame (10). A first support arm (50) can be rotatably coupled to the end portion of the first rotational arm (20), and a second support arm (60) can be rotatably coupled to the end portion of the second rotational arm (30). Accordingly, when the first rotational arm (20) and the second rotational arm (30) move away from each other, the first support arm (50) and the second support arm (60) can also move away from each other, and the first rotational arm (20) and the second rotational arm (30) can also move closer to each other. As an example, the first rotational arm (20) and the second rotational arm (30) can be arranged to be mutually coupled with respect to the frame (10).

[0032] The moving part (40) serves to move the first rotating arm (20) and the second rotating arm (30) in a direction toward each other or toward each other. The moving part (40) may include a handle (41) and two links (42).

[0033] The handle (41) is positioned between the first rotation arm (20) and the second rotation arm (30) on the frame (10) and can be coupled to reciprocate along a vertical direction perpendicular to the central axis of the frame (10). For example, the handle (41) can be screw-coupled to the frame (10) so as to reciprocate along a vertical direction perpendicular to the central axis of the frame (10). Here, a screw hole for screw coupling with the handle (41) may be formed in the frame (10), and the handle (41) may have a screw shaft shape.

[0034] The two links (42) can convert the reciprocating movement of the handle (41) in the frame (10) into a movement of the first rotation arm (20) and the second rotation arm (30) moving away from each other or moving closer to each other. To this end, one side of each of the two links (42) may be hinged to both sides of the handle (41), and the other side of each of the two links (42) may be hinged to the inner side of the first rotation arm (20) and the inner side of the second rotation arm (30).

[0035] For example, if the handle (41) moves in a direction that moves closer to the two links (42), the two links (42) move away from each other, and the first rotation arm (20) and the second rotation arm (30) can move away from each other.

[0036] As another example, if the handle (41) moves away from the two links (42), the two links (42) move closer to each other, and the first rotation arm (20) and the second rotation arm (30) can move closer to each other.

[0037] Meanwhile, two links (42) can be arranged symmetrically with respect to the frame (10).

[0038] The first support arm (50) is rotatably coupled to the first rotation arm (20) and can serve to support the upper eyelid. This first support arm (50) may include a first connecting part (51) and a first bending part (52).

[0039] The first connecting part (51) can be rotatably coupled to the first rotating arm (20). For example, the first connecting part (51) can be coupled coaxially with the first rotating arm (20). For another example, the first connecting part (51) can be coupled offsetly with the first rotating arm (20).

[0040] The first curved portion (52) extends in an arc shape from the first connecting portion (51) and can be inserted into the inner side of the upper eyelid to support the upper eyelid. Here, the inner side of the upper eyelid may be between the inner surface of the upper eyelid and the outer surface of the eyeball.

[0041] For example, the end portion of the first bend (52) may protrude in a direction away from the second support arm (60).

[0042] The second support arm (60) is rotatably coupled to the second rotation arm (30) and can serve to support the lower eyelid. This second support arm (60) may include a second connecting part (61) and a second bending part (62).

[0043] The second connecting part (61) can be rotatably coupled to the second rotating arm (30). For example, the second connecting part (61) can be coupled coaxially with the second rotating arm (30). For another example, the first connecting part (51) can be coupled offsetly with the second rotating arm (30).

[0044] The second curved portion (62) extends in an arc shape from the second connecting portion (61) and can be inserted into the inner side of the lower eyelid to support the lower eyelid. Here, the inner side of the lower eyelid may be between the inner surface of the lower eyelid and the outer surface of the eyeball.

[0045] For example, the end portion of the second bend (62) may protrude in a direction away from the first support arm (50).

[0046] For example, when the first bend (52) and the second bend (62) are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, the first bend (52) may be rotated and aligned into the inner side of the upper eyelid as the upper eyelid pushes the first bend (52), and the second bend (62) may be rotated and aligned into the inner side of the lower eyelid as the lower eyelid pushes the second bend (62). Therefore, when the first bend (52) and the second bend (62) are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, contact between the first bend (52) and the cornea of ​​the eye may be prevented, and contact between the second bend (62) and the cornea of ​​the eye may also be prevented. For reference, the rotation of the first bend (52) can be achieved by the relative rotation of the first connecting part (51) with respect to the first rotating arm (20). Additionally, the rotation of the second bend (62) can be achieved by the relative rotation of the second connecting part (61) with respect to the second rotating arm (30).

[0047] Afterward, when the first curved part (52) inserted into the inner side of the upper eyelid and the second curved part (62) inserted into the inner side of the lower eyelid are discharged, the first curved part (52) is rotated toward the upper eyelid to be separated from the cornea of ​​the eye, and the second curved part (62) is rotated toward the lower eyelid to be separated from the cornea of ​​the eye, and the first curved part (52) and the second curved part (62) can be discharged. As a result, when the first curved part (52) inserted into the inner side of the upper eyelid and the second curved part (62) inserted into the inner side of the lower eyelid are discharged, contact between the first curved part (52) and the cornea of ​​the eye can be prevented, and contact between the second curved part (62) and the cornea of ​​the eye can also be prevented.

[0048] For example, the first bend (52) may be composed of multiple first bends, and multiple first bends (52) may be arranged along the first connecting part (51). For another example, referring to FIG. 1, the first bend (52) may be composed of two, and two first bends (52) may be arranged along the first connecting part (51).

[0049] For example, the second bend (62) may be composed of multiple parts, and multiple second bends (62) may be arranged along the second connecting part (61). For another example, referring to FIG. 1, the second bend (62) may be composed of two parts, and two second bends (62) may be arranged along the second connecting part (61).

[0050] An eye opening device according to the first embodiment of the present invention may include a first hinge part (70), a second hinge part (80), a first locking part (90), and a second locking part (100).

[0051] The first hinge portion (70) can connect the first support arm (50) to the first rotational arm (20) so as to rotate relative to the first rotational arm (20) in the circumferential direction of the first rotational arm (20). Referring to FIG. 1, the first hinge portion (70) can connect the first connecting portion (51) to the first rotational arm (20) so as to rotate relative to the first rotational arm (20) in the circumferential direction of the first rotational arm (20).

[0052] The first hinge portion (70) may include a first fixed shaft (71) and a first hinge shaft (72). Here, the first fixed shaft (71) may be coupled to the end portion of the first rotating arm (20). Additionally, the first hinge shaft (72) may be rotatably coupled to the first fixed shaft (71) in the circumferential direction of the first rotating arm (20) and coupled to the end portion of the first connecting portion (51). For example, the first fixed shaft (71) and the first hinge shaft (72) may have an annular shape.

[0053] The second hinge portion (80) can connect the second support arm (60) to the second rotation arm (30) so as to rotate relative to the second rotation arm (30) in the circumferential direction of the second rotation arm (30). Referring to FIG. 1, the second hinge portion (80) can connect the second connecting portion (61) to the second rotation arm (30) so as to rotate relative to the second rotation arm (30) in the circumferential direction of the second rotation arm (30).

[0054] The second hinge portion (80) may include a second fixed shaft (81) and a second hinge shaft (82). Here, the second fixed shaft (81) may be coupled to the end portion of the second rotating arm (30). Additionally, the second hinge shaft (82) may be rotatably coupled to the second fixed shaft (81) in the circumferential direction of the second rotating arm (30) and coupled to the end portion of the second connecting portion (61). For example, the second fixed shaft (81) and the second hinge shaft (82) may have an annular shape.

[0055] The first locking part (90) can serve to lock or unlock the first support arm (50) to the first rotation arm (20).

[0056] The first locking part (90) may use a first bolt that is screw-coupled to the first hinge shaft (72) of the first hinge part (70) and tightened or loosened to the first fixed shaft (71) of the first hinge part (70). For example, when the first bolt is tightened to the first fixed shaft (71), the first support arm (50) can be locked to the first rotation arm (20) as the first hinge shaft (72) and the first fixed shaft (71) are locked. Additionally, when the first bolt is loosened from the first fixed shaft (71), the first support arm (50) can be loosened from the first rotation arm (20) as the first hinge shaft (72) and the first fixed shaft (71) are loosened.

[0057] The second locking part (100) can serve to lock or unlock the second support arm (60) to the second rotation arm (30).

[0058] The second locking part (100) may use a second bolt that is screw-coupled to the second hinge shaft (82) of the second hinge part (80) and tightened or untightened to the second fixed shaft (81) of the second hinge part (80). For example, when the second bolt is tightened to the second fixed shaft (81), the second hinge shaft (82) and the second fixed shaft (81) are locked, and the second support arm (60) can be locked to the second rotation arm (30). Additionally, when the second bolt is untightened from the second fixed shaft (81), the second hinge shaft (82) and the second fixed shaft (81) are unlocked, and the first support arm (50) can be unlocked to the second rotation arm (30).

[0059] Hereinafter, the process of opening the upper and lower eyelids of the eyelid disc opening device according to the first embodiment of the present invention will be described. The following process may be performed by a practitioner or a robotic arm.

[0060] First, the first bend (52) of the first support arm (50) and the second bend (62) of the second support arm (60) are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively. At this time, as the upper eyelid pushes the first bend (52), the first bend (52) rotates and aligns with the inner side of the upper eyelid, and as the lower eyelid pushes the second bend (62), the second bend (62) rotates and aligns with the inner side of the lower eyelid. Accordingly, when the first bend (52) and the second bend (62) are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, the first bend (52) and the second bend (62) are aligned into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, so that contact between the first bend (52) and the cornea of ​​the eye can be prevented, and contact between the second bend (62) and the cornea of ​​the eye can also be prevented.

[0061] Next, as needed, the angle at which the first bending part (52) connected to the first connecting part (51) supports the upper eyelid can be adjusted by rotating the first connecting part (51) of the first support arm (50) through the first hinge part (70), and the angle at which the second bending part (62) connected to the second connecting part (61) supports the lower eyelid can be adjusted by rotating the second connecting part (61) and the second bending part (62) of the second support arm (60) through the second hinge part (80).

[0062] Next, the first locking part (90) locks the first connecting part (51) to the first rotating arm (20), and the second locking part (100) locks the second connecting part (61) to the second rotating arm (30). As a result, the angle at which the first bending part (52) supports the upper eyelid and the angle at which the second bending part (62) supports the lower eyelid can both be fixed.

[0063] Subsequently, the moving part (40) moves the first rotation arm (20) and the second rotation arm (30) in a direction away from each other. At this time, as the first connecting part (51) and the second connecting part (61) move away from each other, and the first bending part (52) supported by the upper eyelid and the second bending part (62) supported by the lower eyelid also move away from each other, the upper eyelid and the lower eyelid separate. At this time, since a field of view for eye surgery is secured, eye surgery can be performed.

[0064] After that, when the first bend (52) inserted into the inner side of the upper eyelid and the second bend (62) inserted into the inner side of the lower eyelid are discharged, the first bend (52) is rotated in a direction toward the upper eyelid to be separated from the cornea of ​​the eye, and the second bend (62) is rotated in a direction toward the lower eyelid to be separated from the cornea of ​​the eye, and then the moving part (40) moves the first rotation arm (20) and the second rotation arm (30) in a direction that brings them closer to each other. At this time, the first connecting part (51) and the second connecting part (61) move in a direction that brings them closer to each other, and the first bending part (52) supported by the upper eyelid and the second bending part (62) supported by the lower eyelid also move in a direction that brings them closer to each other while being spaced apart from the cornea of ​​the eye, and the first bending part (52) and the second bending part (62) can be discharged from the inner side of the upper eyelid and the inner side of the lower eyelid, respectively. As a result, when the first bending part (52) inserted into the inner side of the upper eyelid and the second bending part (62) inserted into the inner side of the lower eyelid are discharged, contact between the first bending part (52) and the cornea of ​​the eye can be prevented, and contact between the second bending part (62) and the cornea of ​​the eye can also be prevented.

[0065] FIG. 4 is a perspective view showing an eye opening device according to a second embodiment of the present invention, FIG. 5 is a perspective view showing the state in which the first and second curved parts are moved through the guide rail of the eye opening device according to the second embodiment of the present invention, and FIG. 6 is a cross-sectional view showing the state in which the first and second curved parts are moved along the circumference of the eye through the guide rail of the eye opening device according to the second embodiment of the present invention.

[0066] As illustrated in FIGS. 4 to 6, the eye examination device according to the second embodiment of the present invention may further include a guide rail (110).

[0067] The guide rail (110) can serve to guide the movement path of the first connecting part (51) and the second connecting part (61) into an arc-shaped path corresponding to the circumference of the eyeball so that when the first bending part (52) supported on the inner side of the upper eyelid and the second bending part (62) supported on the inner side of the lower eyelid move in a direction that spreads or brings the upper and lower eyelids together, the first bending part (52) and the second bending part (62) move along the circumference of the eyeball. The guide rail (110) may include a rail body (111) and a rail hole (112).

[0068] The rail body (111) is the basic body of the guide rail (110). For example, the rail body (111) may have an arc shape. Additionally, the rail body (111) may be supported on the face or an external structure as needed.

[0069] The rail hole (112) is formed through the rail body (111) in an arc shape corresponding to the circumference of the eyeball, and the first connecting part (51) and the second connecting part (61) can be inserted. Here, the first connecting part (51) and the second connecting part (61) can move along the rail hole (112) and move along an arc-shaped path corresponding to the circumference of the eyeball.

[0070] Hereinafter, the examination process of the eye examination device according to the second embodiment of the present invention will be described.

[0071] First, the first bend (52) of the first support arm (50) and the second bend (62) of the second support arm (60) are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively. At this time, as the upper eyelid pushes the first bend (52), the first bend (52) rotates and aligns with the inner side of the upper eyelid, and as the lower eyelid pushes the second bend (62), the second bend (62) rotates and aligns with the inner side of the lower eyelid. Accordingly, when the first bend (52) and the second bend (62) are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, the first bend (52) and the second bend (62) are aligned into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, so that contact between the first bend (52) and the cornea of ​​the eye can be prevented, and contact between the second bend (62) and the cornea of ​​the eye can also be prevented.

[0072] Next, as needed, the angle at which the first bending part (52) connected to the first connecting part (51) supports the upper eyelid can be adjusted by rotating the first connecting part (51) of the first support arm (50) through the first hinge part (70), and the angle at which the second bending part (62) connected to the second connecting part (61) supports the lower eyelid can be adjusted by rotating the second connecting part (61) and the second bending part (62) of the second support arm (60) through the second hinge part (80).

[0073] Next, the first locking part (90) locks the first connecting part (51) to the first rotating arm (20), and the second locking part (100) locks the second connecting part (61) to the second rotating arm (30). As a result, the angle at which the first bending part (52) supports the upper eyelid and the angle at which the second bending part (62) supports the lower eyelid can both be fixed.

[0074] Subsequently, the moving part (40) moves the first rotating arm (20) and the second rotating arm (30) in a direction away from each other. At this time, the first connecting part (51) and the second connecting part (61) move along the rail hole of the guide rail (110) in an arc-shaped path corresponding to the circumference of the eyeball, and the first bending part (52) supported by the upper eyelid and the second bending part (62) supported by the lower eyelid also move in an arc-shaped path corresponding to the circumference of the eyeball. As a result, as the distance traveled by the first bending part (52) and the second bending part (62) increases, the first bending part (52) and the second bending part (62) are firmly supported on the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, thereby preventing the first bending part (52) and the second bending part (62) from detaching from the upper eyelid and the lower eyelid, respectively. Since a field of view for eye surgery has been secured during this process, the eye surgery can be performed.

[0075] Afterwards, when the first bend (52) inserted into the inner side of the upper eyelid and the second bend (62) inserted into the inner side of the lower eyelid are discharged, the moving part (40) moves the first rotating arm (20) and the second rotating arm (30) in a direction that brings them closer to each other. At this time, the first connecting part (51) and the second connecting part (61) move along the rail hole of the guide rail (110) in an arc-shaped path corresponding to the circumference of the eyeball, and the first bend (52) supported by the upper eyelid and the second bend (62) supported by the lower eyelid also move along an arc-shaped path corresponding to the circumference of the eyeball, and the first bend (52) and the second bend (62) can be discharged from the inner side of the upper eyelid and the inner side of the lower eyelid, respectively. As a result, when the first curved portion (52) inserted into the inner side of the upper eyelid and the second curved portion (62) inserted into the inner side of the lower eyelid are discharged, contact between the first curved portion (52) and the cornea of ​​the eye can be prevented, and contact between the second curved portion (62) and the cornea of ​​the eye can also be prevented.

[0076] FIG. 7 is a perspective view showing an eye opening device according to a third embodiment of the present invention.

[0077] As illustrated in FIG. 7, the eye examination device according to the third embodiment of the present invention may further include a connector (120) connecting the rail body and the frame (10), unlike the second embodiment.

[0078] In this embodiment, the rail body (111) can be supported on the frame (10) through the connector (120).

[0079] In this embodiment, a first pad (53) having a wider width than the first bend (52) may be provided at the end of the first bend (52), and a second pad (63) having a wider width than the second bend (62) may be provided at the end of the second bend (62).

[0080] According to the present invention, an eye examination device according to one embodiment of the present invention has the effect of preventing corneal damage and the occurrence of ptosis during eye examination.

[0081] In addition, the eye opening device according to one embodiment of the present invention has the effect of preventing the first and second bends from deviating from the upper and lower eyelids, respectively, by guiding the movement path of the first and second connecting parts along the circumference of the eyeball in an arc shape corresponding to the circumference of the eyeball when the first bend and the second bend are supported on the upper eyelid and the second bend are moved in a direction that spreads or brings the upper and lower eyelids apart or together, respectively, so that the guide rail guides the first and second bends along the circumference of the eyeball.

[0082] Conventional eyelid retractors often detach from the upper and lower eyelids as they are opened more widely to secure a surgical field of view. This is because the upper and lower eyelids separate from the eyeball as they are opened more widely. However, in the present invention, the first and second bending parts move along the circumference of the eyeball and perform retracting to open the upper and lower eyelids; thus, even when opened widely to secure a surgical field of view, the eyelids do not loosen but rather tighten more firmly. Therefore, the retracting of the upper and lower eyelids can be ensured.

[0083] In addition, the present invention allows for the creation of double eyelids when the eyeball is opened, and has cosmetic advantages. This is because the direction of the force exerted by the first and second bending parts to spread the upper and lower eyelids is the same as the direction of the force used during double eyelid surgery, and is similar to the effect of using double eyelid tape.

[0084] In addition, the present invention can secure a more effective surgical field of view. That is, since the first and second bending parts move along the circumference of the eyeball and perform an eye opening that separates the upper and lower eyelids, a wider surgical field of view than that of conventional eye discectomizers can be secured, thereby providing a more effective surgical field of view. This can be explained geometrically.

[0085] Furthermore, the present invention can prevent corneal damage. Conventional eyelid retractors had a structure in which two metal bars were inserted into the medial side of the upper eyelid and the medial side of the lower eyelid, respectively, to open the eyelids. However, these two metal bars frequently came into contact with the cornea located in the center of the eye, often causing corneal damage. Consequently, the operator faced the inconvenience of having to be cautious at all times to prevent corneal damage, and the process of lifting the eyelid to insert the retractor to prevent corneal damage was inherently vulnerable to causing damage to the eyelid. In contrast, when the first and second curved sections of the present invention are inserted into the upper and lower eyelids, respectively, they are inserted into the peripheral areas where there is no cornea (e.g., the empty spaces near the nose and ears = medial conjunctiva, lateral conjunctiva), thus eliminating the risk of corneal damage. Additionally, since it opens the empty spaces near the nose and ears—which are frequently used during vitrectomy—more effectively, it is more advantageous for securing the surgical field of view.

[0086] In addition, when the upper and lower eyelids are opened, the backbone located on the outside rotates simultaneously. Therefore, the upper and lower eyelids are automatically rotated outward, allowing the eyelid retractor to be better fitted to the eyeball and opened efficiently. This is because, in order to open the upper and lower eyelids well, the distal ends of the upper and lower eyelids must undergo external rotation.

[0087] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. Explanation of the symbols
