Description

eye exam

[0001] The present invention relates to an eye examination device.

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

[0003] During eye surgery, an eyelid 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, the existing eye examination device had a problem in that the two metal bars, inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, and then removed, caused the two metal bars to come into contact with or press on the cornea of ​​the eye, resulting in damage to the cornea.

[0005] In addition, when the two metal bars supporting the upper and lower eyelids are moved in a direction that spreads the upper and lower eyelids apart, the metal bars that spread the upper eyelids press the upper eyelids against the frontal bone because the direction of movement of the two metal bars is parallel to the face. As a result, there was a problem in that the levator palpebrae superioris muscle was crushed by the metal bars that spread the upper eyelids against the frontal bone, causing ptosis.

[0006] Here, ptosis is a disease in which the upper eyelid droops and covers the eyeball. As the upper eyelid covers the eyeball, it is not aesthetically pleasing, and in severe cases, it can obstruct the visual axis of the eyeball, resulting in reduced vision.

[0007] In addition, the existing eyelid opening device had a problem in that when the two metal bars supported by the upper and lower eyelids moved in the direction of spreading the upper and lower eyelids, the two metal bars would come off from the upper and lower eyelids because the direction of movement of the two metal bars was parallel to the face.

[0008] The present invention has been devised to solve the above-described problems, and the purpose of the present invention is to provide an eye examination device that can prevent damage to the cornea and ptosis of the eyelid during eye examination.

[0009] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] An eyelid opener according to one embodiment of the present invention comprises: a frame; a first rotating arm rotatably coupled to one side of the frame; a second rotating arm rotatably coupled to the other side of the frame; a moving unit that moves the first rotating arm and the second rotating arm toward each other or away from each other; a first support arm rotatably coupled to the first rotating arm and supporting an upper eyelid; and a second support arm rotatably coupled to the second rotating arm and supporting a lower eyelid.

[0011] In addition, the device may further include a first hinge portion that connects the first support arm to the first rotation arm so that the first support arm can rotate relative to the first rotation arm in the circumferential direction of the first rotation arm; and a second hinge portion that connects the second support arm to the second rotation arm so that the second support arm can rotate relative to the second rotation arm in the circumferential direction of the second rotation arm.

[0012] In addition, the device may further include a first locking portion for locking or unlocking the first support arm to the first rotation arm; and a second locking portion for locking or unlocking the second support arm to the second rotation arm.

[0013] In addition, the first support arm may include a first connecting portion rotatably coupled to the first rotation arm; and a first curved portion extending from the first connecting portion in an arc shape and inserted into the inner side of the upper eyelid to support the upper eyelid, and the second support arm may include a second connecting portion rotatably coupled to the second rotation arm; and a second curved portion extending from the second connecting portion in an arc shape and inserted into the inner side of the lower eyelid to support the lower eyelid.

[0014] In addition, when the first bending portion and the second bending portion are inserted into the inner side of the upper eyelid and the inner side of the lower eyelid, respectively, the first bending portion can be rotated to be aligned to the inner side of the upper eyelid, and the second bending portion can be rotated to be aligned to the inner side of the lower eyelid.

[0015] In addition, the first bending portion may be configured in plurality, and the plurality of first bending portions may be arranged along the first connecting portion, and the second bending portion may be configured in plurality, and the plurality of second bending portions may be arranged along the second connecting portion.

[0016] In addition, when the first bending portion and the second bending portion move in a direction that spreads or gathers the upper and lower eyelids, a guide rail may be further included that guides the movement path of the first connecting portion and the second connecting portion along an arc-shaped path corresponding to the circumference of the eyeball so that the first bending portion and the second bending portion move along the circumference of the eyeball.

[0017] In addition, the guide rail may include a rail body; and a rail hole formed in an arc shape penetrating the rail body, into which the first connecting portion and the second connecting portion are inserted.

[0018] Other specific details of the present invention are included in the detailed description and drawings.

[0019] An eye examination device according to one embodiment of the present invention has the effect of preventing damage to the cornea and occurrence of ptosis during eye examination.

[0020] In addition, the eye examination device according to one embodiment of the present invention has the effect of preventing the first bending part and the second bending part from being separated from the upper eyelid and the lower eyelid, respectively, by guiding the movement path of the first connecting part and the second connecting part along an arc-shaped path corresponding to the circumference of the eyeball so that the first bending part and the second bending part move along the circumference of the eyeball when the first bending part supported on the upper eyelid and the second bending part supported on the lower eyelid move in a direction that spreads or gathers the upper and lower eyelids, respectively.

[0021] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

[0029] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided solely 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 solely by the scope of the claims.

[0030] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in their common sense to those skilled in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0031] Before describing the present invention, in several embodiments, components having the same configuration will be described representatively in the first embodiment using the same reference numerals, and in other embodiments, configurations different from the first embodiment will be described.

[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0033] FIG. 1 is a perspective view showing an eye speculum 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 speculum according to a first embodiment of the present invention, and FIG. 3 is a perspective view showing an eye speculum according to a first embodiment of the present invention with the upper and lower eyelids spread apart.

[0034] As illustrated in FIGS. 1 to 3, an eye examination device according to a first embodiment of the present invention may include a frame (10), a first rotating arm (20), a second rotating arm (30), a moving part (40), a first support arm (50), and a second support arm (60).

[0035] The frame (10) is the basic body of the present invention. A first rotation arm (20) and a second rotation arm (30) can be rotatably coupled to both sides of the frame (10).

[0036] The first rotary arm (20) may be rotatably coupled to one side of the frame (10), and the second rotary arm (30) may be rotatably coupled to the other side of the frame (10). A first support arm (50) may be rotatably coupled to a distal end of the first rotary arm (20), and a second support arm (60) may be rotatably coupled to a distal end of the second rotary arm (30). Accordingly, when the first rotary arm (20) and the second rotary arm (30) move away from each other, the first support arm (50) and the second support arm (60) may also move away from each other, and the first rotary arm (20) and the second rotary arm (30) may also move toward each other. For example, the first rotary arm (20) and the second rotary arm (30) may be arranged to be aligned with each other with respect to the frame (10).

[0037] The moving part (40) serves to move the first rotary arm (20) and the second rotary arm (30) toward each other or away from each other. The moving part (40) may include a handle (41) and two links (42).

[0038] The handle (41) may be arranged between the first rotary arm (20) and the second rotary arm (30) in the frame (10) and may be coupled so as to be reciprocally movable along a vertical direction perpendicular to the central axis of the frame (10). For example, the handle (41) may be screw-coupled to the frame (10) so as to be reciprocally movable along a vertical direction perpendicular to the central axis of the frame (10). Here, a screw hole for screw-connecting with the handle (41) may be formed in the frame (10), and the handle (41) may have a screw shaft shape.

[0039] The two links (42) can serve to convert the reciprocating movement of the handle (41) in the frame (10) into the movement of the first rotary arm (20) and the second rotary arm (30) away from each other or toward each other. To this end, one side of the two links (42) can be hinge-connected to both sides of the handle (41), and the other side of the two links (42) can be hinge-connected to the inner side of the first rotary arm (20) and the inner side of the second rotary arm (30), respectively.

[0040] For example, when the handle (41) moves in a direction closer to the two links (42), the two links (42) move in a direction away from each other, and the first rotation arm (20) and the second rotation arm (30) can move in a direction away from each other.

[0041] As another example, when the handle (41) moves away from the two links (42), the two links (42) may move toward each other, and the first rotation arm (20) and the second rotation arm (30) may move toward each other.

[0042] Meanwhile, two links (42) can be arranged symmetrically with respect to the frame (10).

[0043] The first support arm (50) can be rotatably connected to the first rotation arm (20) and can serve to support the upper eyelid. The first support arm (50) can include a first connecting portion (51) and a first bending portion (52).

[0044] The first connecting portion (51) can be rotatably coupled to the first rotary arm (20). For example, the first connecting portion (51) can be coupled coaxially with the first rotary arm (20). In another example, the first connecting portion (51) can be coupled misaligned with the first rotary arm (20).

[0045] The first bending 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 can be between the inner surface of the upper eyelid and the outer surface of the eyeball.

[0046] For example, the distal end of the first bend (52) may protrude in a direction away from the second support arm (60).

[0047] The second support arm (60) can be rotatably connected to the second rotation arm (30) and can serve to support the lower eyelid. The second support arm (60) can include a second connecting portion (61) and a second bending portion (62).

[0048] The second connecting portion (61) can be rotatably coupled to the second rotating arm (30). For example, the second connecting portion (61) can be coupled coaxially with the second rotating arm (30). As another example, the first connecting portion (51) can be coupled misaligned with the second rotating arm (30).

[0049] The second bending 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 can be between the inner surface of the lower eyelid and the outer surface of the eyeball.

[0050] For example, the distal end of the second bend (62) may protrude in a direction away from the first support arm (50).

[0051] 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) can be rotated and aligned to the inner side of the upper eyelid as the upper eyelid pushes the first bend (52), and when the lower eyelid pushes the second bend (62), the second bend (62) can be rotated and aligned to 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, 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. For reference, the rotation of the first bending portion (52) can be achieved by the relative rotation of the first connecting portion (51) with respect to the first rotating arm (20). In addition, the rotation of the second bending portion (62) can be achieved by the relative rotation of the second connecting portion (61) with respect to the second rotating arm (30).

[0052] Thereafter, 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) can be rotated in the direction toward the upper eyelid to be separated from the cornea of ​​the eyeball, and the second curved part (62) can be rotated in the direction toward the lower eyelid to be separated from the cornea of ​​the eyeball, and in this state, 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 eyeball can be prevented, and contact between the second curved part (62) and the cornea of ​​the eyeball can also be prevented.

[0053] For example, the first bending portion (52) may be composed of multiple first bending portions (52), and the multiple first bending portions (52) may be arranged along the first connecting portion (51). In another example, referring to Fig. 1, the first bending portion (52) may be composed of two first bending portions (52), and the two first bending portions (52) may be arranged along the first connecting portion (51).

[0054] For example, the second bending portion (62) may be configured in multiples, and the multiple second bending portions (62) may be arranged along the second connecting portion (61). In another example, referring to Fig. 1, the second bending portion (62) may be configured in twos, and the two second bending portions (62) may be arranged along the second connecting portion (61).

[0055] The eye examination 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).

[0056] The first hinge portion (70) can couple the first support arm (50) to the first rotation arm (20) so that the first rotation arm (20) can rotate relative to the first support arm (50) in the circumferential direction of the first rotation arm (20). Referring to Fig. 1, the first hinge portion (70) can couple the first connection portion (51) to the first rotation arm (20) so that the first rotation arm (20) can rotate relative to the first support arm (50) in the circumferential direction of the first rotation arm (20).

[0057] The first hinge portion (70) may include a first fixed axis (71) and a first hinge axis (72). Here, the first fixed axis (71) may be coupled to the distal end of the first rotary arm (20). In addition, the first hinge axis (72) may be coupled to the first fixed axis (71) so as to be rotatable in the circumferential direction of the first rotary arm (20) and may be coupled to the distal end of the first connecting portion (51). For example, the first fixed axis (71) and the first hinge axis (72) may have a ring shape.

[0058] The second hinge portion (80) can couple the second support arm (60) to the second rotation arm (30) so that the second rotation arm (30) can rotate relative to the second support arm (60) in the circumferential direction of the second rotation arm (30). Referring to Fig. 1, the second hinge portion (80) can couple the second connection portion (61) to the second rotation arm (30) so that the second rotation arm (30) can rotate relative to the second connection portion (61) in the circumferential direction of the second rotation arm (30).

[0059] The second hinge portion (80) may include a second fixed axis (81) and a second hinge axis (82). Here, the second fixed axis (81) may be coupled to the distal end of the second rotary arm (30). In addition, the second hinge axis (82) may be coupled to the second fixed axis (81) so as to be rotatable in the circumferential direction of the second rotary arm (30) and may be coupled to the distal end of the second connecting portion (61). For example, the second fixed axis (81) and the second hinge axis (82) may have a ring shape.

[0060] The first locking part (90) can play a role in locking or unlocking the first support arm (50) to the first rotation arm (20).

[0061] The first locking portion (90) may be screw-connected to the first hinge axis (72) of the first hinge portion (70), and a first bolt that is tightened or released from the first fixed axis (71) of the first hinge portion (70) may be used. For example, when the first bolt is tightened to the first fixed axis (71), the first hinge axis (72) and the first fixed axis (71) are locked, so that the first support arm (50) can be locked with the first rotation arm (20). In addition, when the first bolt is released from the first fixed axis (71), the first hinge axis (72) and the first fixed axis (71) are unlocked, so that the first support arm (50) can be unlocked with the first rotation arm (20).

[0062] The second locking part (100) can play a role in locking or unlocking the second support arm (60) to the second rotation arm (30).

[0063] The second locking portion (100) may use a second bolt that is screw-connected to the second hinge axis (82) of the second hinge portion (80) and is tightened or released from the second fixed axis (81) of the second hinge portion (80). For example, when the second bolt is tightened to the second fixed axis (81), the second hinge axis (82) and the second fixed axis (81) are locked, so that the second support arm (60) can be locked with the second rotation arm (30). In addition, when the second bolt is released from the second fixed axis (81), the first support arm (50) can be unlocked with the second rotation arm (30) as the second hinge axis (82) and the second fixed axis (81) are unlocked.

[0064] Hereinafter, the upper and lower eyelid opening processes of the eyelid opening device according to the first embodiment of the present invention will be described. The following process can be performed by a practitioner or a robotic arm.

[0065] 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 is aligned to the inner side of the upper eyelid, and as the lower eyelid pushes the second bend (62), the second bend (62) rotates and is aligned to 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, and the first bend (52) and the second bend (62) are aligned to 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 can be prevented, and contact between the second bend (62) and the cornea of ​​the eye can also be prevented.

[0066] Next, as needed, the first connecting portion (51) of the first support arm (50) can be rotated through the first hinge portion (70) to adjust the angle at which the first curved portion (52) connected to the first connecting portion (51) supports the upper eyelid, and the second connecting portion (61) and the second curved portion (62) of the second support arm (60) can be rotated through the second hinge portion (80) to adjust the angle at which the second curved portion (62) connected to the second connecting portion (61) supports the lower eyelid.

[0067] Next, the first locking portion (90) locks the first connecting portion (51) to the first rotating arm (20), and the second locking portion (100) locks the second connecting portion (61) to the second rotating arm (30). As a result, both the angle at which the first bending portion (52) supports the upper eyelid and the angle at which the second bending portion (62) supports the lower eyelid can be fixed.

[0068] Thereafter, the moving part (40) moves the first rotation arm (20) and the second rotation arm (30) away from each other. At this time, the first connecting part (51) and the second connecting part (61) move away from each other, and the first bending part (52) supported on the upper eyelid and the second bending part (62) supported on the lower eyelid also move away from each other, thereby causing the upper and lower eyelids to spread apart. At this time, since a field of vision for eye surgery is secured, eye surgery can be performed.

[0069] Thereafter, 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, the first bending part (52) is rotated in the direction toward the upper eyelid to separate it from the cornea of ​​the eyeball, and the second bending part (62) is rotated in the direction toward the lower eyelid to separate it from the cornea of ​​the eyeball, and 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 portion (51) and the second connecting portion (61) move toward each other, and the first curved portion (52) supported on the upper eyelid and the second curved portion (62) supported on the lower eyelid also move toward each other while being spaced apart from the cornea of ​​the eye, so that the first curved portion (52) and the second curved portion (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.

[0070] FIG. 4 is a perspective view showing an eye speculum according to a second embodiment of the present invention, FIG. 5 is a perspective view showing a state in which the first bending portion and the second bending portion are moved through a guide rail of the eye speculum according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view showing a state in which the first bending portion and the second bending portion are moved along the circumference of the eye through a guide rail of the eye speculum according to a second embodiment of the present invention.

[0071] As shown 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).

[0072] The guide rail (110) may guide the movement path of the first connecting portion (51) and the second connecting portion (61) along an arc-shaped path corresponding to the circumference of the eyeball so that the first bending portion (52) and the second bending portion (62) supported on the inner side of the upper eyelid and the second bending portion (62) supported on the inner side of the lower eyelid move in a direction that spreads or gathers the upper and lower eyelids, respectively, so that the first bending portion (52) and the second bending portion (62) move along the circumference of the eyeball. The guide rail (110) may include a rail body (111) and a rail hole (112).

[0073] The rail body (111) is the basic body of the guide rail (110). For example, the rail body (111) may have an arc shape. In addition, the rail body (111) may be supported on the face or an external structure, as needed.

[0074] A rail hole (112) is formed through the rail body (111) in an arc shape corresponding to the circumference of the eye, and a first connecting portion (51) and a second connecting portion (61) can be inserted therein. Here, the first connecting portion (51) and the second connecting portion (61) can move along the rail hole (112) and move in an arc shape corresponding to the circumference of the eye.

[0075] Hereinafter, the opening process of the eye examination device according to the second embodiment of the present invention will be described.

[0076] 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 is aligned to the inner side of the upper eyelid, and as the lower eyelid pushes the second bend (62), the second bend (62) rotates and is aligned to 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, and the first bend (52) and the second bend (62) are aligned to 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 can be prevented, and contact between the second bend (62) and the cornea of ​​the eye can also be prevented.

[0077] Next, as needed, the first connecting portion (51) of the first support arm (50) can be rotated through the first hinge portion (70) to adjust the angle at which the first curved portion (52) connected to the first connecting portion (51) supports the upper eyelid, and the second connecting portion (61) and the second curved portion (62) of the second support arm (60) can be rotated through the second hinge portion (80) to adjust the angle at which the second curved portion (62) connected to the second connecting portion (61) supports the lower eyelid.

[0078] Next, the first locking portion (90) locks the first connecting portion (51) to the first rotating arm (20), and the second locking portion (100) locks the second connecting portion (61) to the second rotating arm (30). As a result, both the angle at which the first bending portion (52) supports the upper eyelid and the angle at which the second bending portion (62) supports the lower eyelid can be fixed.

[0079] Thereafter, the moving part (40) moves the first rotation arm (20) and the second rotation arm (30) 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 on the upper eyelid and the second bending part (62) supported on the lower eyelid also move in an arc-shaped path corresponding to the circumference of the eyeball. As a result, as the moving distance of 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, so that the first bending part (52) and the second bending part (62) can be prevented from being separated from the upper eyelid and the lower eyelid, respectively. Since the field of vision for eye surgery has been secured during this process, eye surgery can be performed.

[0080] Thereafter, 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, the moving part (40) moves the first rotation arm (20) and the second rotation arm (30) in a direction in which they become closer to each other. At this time, the first connecting part (51) and the second connecting part (61) move in an arc-shaped path corresponding to the circumference of the eyeball along the rail hole of the guide rail (110), and the first bending part (52) supported on the upper eyelid and the second bending part (62) supported on the lower eyelid also move in an arc-shaped path corresponding to the circumference of the eyeball, 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 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, 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.

[0081] Fig. 7 is a perspective view showing an eye examination device according to a third embodiment of the present invention.

[0082] 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.

[0083] In this embodiment, the rail body (111) can be supported on the frame (10) via a connector (120).

[0084] In this embodiment, a first pad (53) having a width greater than that of the first bend (52) may be provided at the end of the first bend (52), and a second pad (63) having a width greater than that of the second bend (62) may be provided at the end of the second bend (62).

[0085] According to the present invention, the eye examination device according to one embodiment of the present invention has the effect of preventing damage to the cornea and occurrence of ptosis when performing eye examination.

[0086] In addition, the eye examination device according to one embodiment of the present invention has the effect of preventing the first bending part and the second bending part from being separated from the upper eyelid and the lower eyelid, respectively, by guiding the movement path of the first connecting part and the second connecting part along an arc-shaped path corresponding to the circumference of the eyeball so that the first bending part and the second bending part move along the circumference of the eyeball when the first bending part supported on the upper eyelid and the second bending part supported on the lower eyelid move in a direction that spreads or gathers the upper and lower eyelids, respectively.

[0087] Conventional eyelid speculum devices often disengage from the upper and lower eyelids as the upper and lower eyelids are spread further apart to secure a surgical field. This is because the upper and lower eyelids separate from the eyeball as they are spread further apart. However, the present invention utilizes the first and second bends to move around the eyeball and spread the upper and lower eyelids apart. Therefore, even when the eyelids are spread widely to secure a surgical field, the eyelids do not loosen; rather, they are tightened more firmly. Consequently, the opening of the upper and lower eyelids can be ensured.

[0088] Furthermore, the present invention can create a double eyelid during eyelid surgery, and has cosmetic advantages. This is because the direction of force applied by the first and second folds to separate the upper and lower eyelids is the same as that applied during double eyelid surgery, and the effect is similar to that of applying double eyelid tape.

[0089] Furthermore, the present invention can secure a more effective surgical field of view. Specifically, the first and second flexors move along the circumference of the eyeball, opening the upper and lower eyelids, thereby securing a wider surgical field of view than conventional eye-opening devices, thereby ensuring a more effective surgical field of view. This can be explained geometrically.

[0090] Furthermore, the present invention can prevent corneal damage. Conventional eyelid speculum devices use two metal bars inserted into the inner side of the upper eyelid and the inner side of the lower eyelid to spread the eyelids apart. However, these two metal bars frequently contact the cornea located in the center of the eyeball, often causing corneal damage. Consequently, the surgeon must constantly be careful to prevent corneal damage, which is inconvenient. Furthermore, the process of lifting the eyelid to insert the speculum to prevent corneal damage is vulnerable to corneal damage. In contrast, the present invention eliminates the risk of corneal damage because the first and second bends are inserted into the upper and lower eyelids, respectively, into peripheral areas where there is no cornea (e.g., the medial conjunctiva and lateral conjunctiva), eliminating the need for corneal damage. Furthermore, the device effectively spreads the nasal and temporal spaces, which are frequently used in vitrectomy, thereby enhancing the surgical field of vision.

[0091] Furthermore, when the upper and lower eyelids are opened, the outer backbone rotates simultaneously. Consequently, the upper and lower eyelids automatically rotate to the left, allowing the eyelid to be better positioned on the eye and effectively opened. This is because, for the upper and lower eyelids to be properly opened, the distal ends of the upper and lower eyelids must rotate outward (external rotation).

[0092] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
