CORNEAL ENDOTHELIAL TISSUE TRANSPLANTATION SYSTEM

TECHNICAL FIELD

The present disclosure relates to a corneal endothelial tissue transplantation system.

BACKGROUND ART

An anterior chamber of an eyeball refers to a space in the eyeball surrounded by a cornea, an iris, and a lens, and corneal endothelial tissue transplantation is performed in the anterior chamber of the eyeball. Specifically, corneal endothelial tissue transplantation is performed by inserting corneal endothelial tissue into an anterior chamber of an eyeball, moving the inserted corneal endothelial tissue, and then transplanting the inserted corneal endothelial tissue to a back surface of a cornea.

Meanwhile, an anterior chamber of an eyeball has only a diameter of about 11 mm to about 13 mm and a depth of 3 mm to 4 mm and thus is very narrow. Therefore, there is a problem that, after a corneal endothelial tissue is inserted into an anterior chamber, it is very difficult to insert a tool for move the corneal endothelial tissue to a desired position or to operate the inserted tool.

In particular, since corneal endothelial tissue is very thin tissue with a thickness of about 10 μm, there is also a problem that the tissue may be damaged when the corneal endothelial tissue is handled by using a sharp tool such as forceps.

Due to these problems, corneal endothelial tissue transplantation requires very sophisticated and high-level surgical techniques, and thus the corneal endothelial tissue transplantation may only be performed by medical staff skilled in the art. However, in reality, skilled medical staff who may perform corneal endothelial tissue transplantation are very rare, which makes it difficult for patients in need of corneal endothelial tissue transplantation to receive surgery in a timely manner.

Accordingly, there is a need to develop a means for transplanting corneal endothelial tissue, which is capable of easily and precisely moving corneal endothelial tissue inserted into an anterior chamber and furthermore is capable of ensuring the safety of an eyeball of a patient.

Hereinafter, a corneal endothelial tissue transplantation system according to the present disclosure will be described based on the above-described principles.

The corneal endothelial tissue transplantation system according to an embodiment of the present disclosure may be used for corneal endothelial tissue transplantation.

FIG. 1 is a schematic view for describing corneal endothelial tissue transplantation.

The corneal endothelial tissue transplantation refers to ophthalmic surgery in which cultured corneal endothelial tissue (hereinafter referred to as CET) is inserted into an anterior chamber (hereinafter referred to as AC) of an eyeball and then transplanted to a back surface of a cornea.

Specifically, the corneal endothelial tissue transplantation is performed by inserting the CET into the AC of the eyeball, moving the CET inside the AC of the eyeball, positioning the CET at a position suitable for transplantation, and then attaching the CET to the back surface of the cornea. In this case, the CET may be cultured in a tissue carrier 110 for transporting tissue and then inserted into the AC of the eyeball together with the tissue carrier 110. However, since the AC of the eyeball is a very narrow space, it is very difficult to insert a tool for moving the CET into the AC of the eyeball or to operate the inserted tool. In addition, since the CET is very thin microscopic tissue, there is a high risk of damage to tissue when the CET is handled by using a sharp tool such as forceps.

In order to solve such a problem, according to a corneal endothelial tissue transplantation system 100 according to the present disclosure, there may be provided a corneal endothelial tissue transplantation system 100 capable of easily and precisely manipulating CET without inserting a separate tool into an AC of an eyeball.

FIG. 2 is a schematic block diagram illustrating the corneal endothelial tissue transplantation system 100 according to an embodiment of the present disclosure.

Referring to FIG. 2, the corneal endothelial tissue transplantation system 100 according to an embodiment of the present disclosure may include a tissue carrier 110 to which the CET is attached and inserted into the AC of the eyeball, a magnetic field generation module 120 including at least one magnetic field generator 121 that generates a magnetic field for moving the tissue carrier 110, and a support plate 122 that supports the magnetic field generator 121, and a user input module 140 that receives a signal for controlling the magnetic field generator 121 from a user.

The tissue carrier 110 may be a means for moving the CET. For example, the CET may be cultured on the tissue carrier 110, and the tissue carrier 110 may be inserted into the AC of the eyeball in a state in which the CET is attached thereto. Accordingly, by moving the inserted tissue carrier 110, the CET may be moved together with the tissue carrier 110.

The tissue carrier 110 may be movable by a magnetic field. For example, the tissue carrier 110 may include a magnetic object, and accordingly, when a magnetic field is applied from the outside, the tissue carrier 110 may move in response to the magnetic field.

Details of the tissue carrier 110 will be described below.

The magnetic field generation module 120 may be a means for generating a magnetic field to move the tissue carrier 110.

The magnetic field generation module 120 may include the magnetic field generator 121. The magnetic field generator 121 may be a component that converts supplied electrical energy into magnetic energy. A plurality of magnetic field generators 121 may be disposed, and power supplied to each magnetic field generator 121 may be controlled. Therefore, a user may change power supplied to each magnetic field generator 121 to control the intensity of a magnetic field generated by each magnetic field generator 121, thereby moving the tissue carrier 110.

Details of the magnetic field generation module 120 will be described below.

The corneal endothelial tissue transplantation system 100 according to an embodiment of the present disclosure may further include a controller 130 for controlling each component of the corneal endothelial tissue transplantation system 100.

The controller 130 may be implemented as at least one processor. When the controller 130 is implemented as a plurality of processors, at least some of the plurality of processors may be positioned at a physical separation distance. For example, the controller 130 may correspond to at least one processor. The processor may be implemented as an array of a plurality of logic gates or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable in the microprocessor is stored. In addition, it will be understood by one of ordinary skill in the art that the processor can be implemented in other forms of hardware.

The user input module 140 may be a means for receiving any type of input signal input by a user.

For example, the user input module 140 may be a typical computing input device such as a joystick, a keyboard, a mouse, or a touch screen or may be a means for recognizing a user' voice or eyeball movement, but is not limited thereto. That is, as the user input module 140, any means may be adopted as long as the means may receive any signal through an operation of a user.

When a user performs a specific operation, the user input module 140 may receive a specific signal based on the operation and may transmit the specific signal to the controller 130. Specifically, the user input module 140 may receive a specific signal through an operation of a user and may transmit the specific signal to the controller 130. The controller 130 may receive the signal transmitted by the user input module 140 and may control the magnetic field generator 121 based on the received signal.

As an alternative embodiment, when an input exceeding preset intensity is applied to the user input module 140. the controller 130 may recognize the input as a user input.

For example, when the user input module 140 is a joystick, only when a user moves the joystick in a specific direction with a force that is greater than or equal to a preset force, the controller 130 may recognize such an input as a user input, and when a force less than the preset force is applied, it may be ignored. Therefore, when a minute input such as an input due to a hand tremor of a user is applied to the joystick, such a minute input may be erased, and only when an input exceeding preset intensity is applied, the controller 130 may recognize the input to control the magnetic field generator 121 based on the input.

As an embodiment, the corneal endothelial tissue transplantation system 100 according to an embodiment of the present disclosure may further include an imaging module 150.

The imaging module 150 may be a means for photographing a surgery scene and providing the photographed surgery scene to a user through a screen. The user may perform corneal endothelial transplantation while observing the surgery scene obtained and provided through the imaging module 150 in real time.

The imaging module 150 may be a camera, a microscope, or the like, but is not limited thereto.

As an embodiment, the corneal endothelial tissue transplantation system 100 according to an embodiment of the present disclosure may further include a display module 160.

The display module 160 may be a means for displaying information related to surgery to a user.

As an example, the display module 160 may provide a surgery image obtained from the imaging module 150 to the user.

As another example, the display module 160 may display information, which is related to the intensity or direction of a magnetic field generated by each magnetic field generator 121, to the user.

However, the present disclosure is not limited thereto and the display module 160 may provide the user with various types of information related to corneal endothelial transplantation.

Accordingly, the user may perform corneal endothelial transplantation while observing an image or information provided through the display module 160 in real time.

As the display module 160, any means may be adopted as long as the means may provide the user with an image acquired from the imaging module 150 or information related to surgery.

FIG. 3 is a schematic view illustrating an embodiment of the tissue carrier 110 of FIG. 2.

Referring to FIG. 3, the tissue carrier 110 may be a means for transporting a CET.

In an embodiment, the tissue carrier 110 may be formed in a plate shape to have an area. In this case, the CET may be cultured on one surface of the tissue carrier 110. That is, the cultured CET may be inserted into an AC of an eyeball of a user in a state of being attached to one surface of the tissue carrier 110.

As an alternative embodiment, the tissue carrier 110 may be formed in a plate shape having an area and may be formed in a shape that is convex in one direction. Since the human cornea is formed to have a curved surface, when the tissue carrier 110 is formed to be convex in one direction, the tissue carrier 110 may be more stably attached to the cornea together with the CET later.

As a specific example, the tissue carrier 110 may be formed in a contact lens-like shape. In this case, as the tissue carrier 110, an cornea of another animal may be used, for example, a cornea of a pig may be used, but the present disclosure is not limited thereto.

As an embodiment, the tissue carrier 110 may include a wire 111, and the wire 111 may be formed of a magnetic material. Therefore, when a magnetic field is applied from the outside, the wire 111 may move in response to the magnetic field, and thus the tissue carrier 110 may move.

In an alternative embodiment, the wire 111 may be disposed along a circumference of the tissue carrier 110. Accordingly, when a magnetic field is applied in various directions, the tissue carrier 110 may easily move in response to the magnetic field.

Meanwhile, although a plurality of wires 111 are shown in FIG. 3 to be disposed along the circumference of the tissue carrier 110, the present disclosure 1 is not limited thereto, and of course, the wire 111 may be formed integrally along the circumference of the tissue carrier 110. That is, the wire 111 may be formed integrally along the circumference of the tissue carrier 110, may be provided as two wires 111, or may be provided two or more wires 111.

In an embodiment, in a state in which at least a portion of the tissue carrier 110 is folded, the tissue carrier 110 may be inserted into the AC of the eyeball. For example, the tissue carrier 110 may being inserted into the AC of the eyeball in a state of being folded in various directions and thus may be easily inserted into the AC of the eyeball.

The tissue carrier 110 may be inserted into the AC of the eyeball and then unfolded by a magnetic field. Specifically, the tissue carrier 110 may be inserted into the AC of the eyeball and then exposed to a magnetic field in various directions by the magnetic field generator 121 disposed along the circumference of the tissue carrier 110. Accordingly, a user may easily unfold a folded portion of the tissue carrier 110 by adjusting the relative intensity of various applied magnetic fields.

FIG. 4 is a schematic view illustrating an embodiment of the magnetic field generation module 120 of FIG. 2. FIG. 5 is a schematic view illustrating the magnetic field generator 121 of FIG. 4 viewed from the side. FIG. 6 is an enlarged view of portion A of FIG. 4.

Referring to FIGS. 4 to 6, the corneal endothelial tissue transplantation system 100 according to the present disclosure may include the magnetic field generation module 120.

The magnetic field generation module 120 may generate a magnetic field to move the tissue carrier 110 inserted into an AC of an eyeball of a patient.

The magnetic field generation module 120 may include at least one magnetic field generator 121 that generates a magnetic field for moving the tissue carrier 110, and the support plate 122 that supports the magnetic field generator 121.

The magnetic field generator 121 may convert supplied electrical energy into magnetic energy. To this end, the magnetic field generator 121 may include a core 1211 and a coil.

Specifically, the coil may be wound along an outer circumference surface of the core 1211, and a current supplied from a separately provided power source may flow through the coil. Accordingly, a magnetic flux may be induced on the core 1211, and thus a magnetic field may be generated.

As an embodiment, at least one magnetic field generator 121 may be provided, and more specifically, the plurality of magnetic field generators 121 may be provided. When the plurality of magnetic field generators 121 are provided, a magnetic field may be applied to the tissue carrier 110 in various directions, thereby allowing the tissue carrier 110 to move in various directions.

In a desirable embodiment, referring to FIG. 4, four magnetic field generators 121 may be disposed to face one point as a center. For example, the magnetic field generators 121 may be disposed to form an angle of 90° around one point.

Accordingly, the tissue carrier 110 disposed adjacent to a surgical port 1221 to be described below may be exposed to magnetic fields generated in at least four directions, and thus the tissue carrier 110 may be moved more precisely and efficiently.

However, the present disclosure is not limited thereto, of course, two or three magnetic field generators 121 may be provided, and five or more magnetic field generators 121 may also be provided.

The support plate 122 may be a means for supporting the magnetic field generator 121. For example, the support plate 122 may be formed in a plate shape to have an area, and the plurality of magnetic field generators 121 may be disposed on one surface of the support plate 122.

As an embodiment, the support plate 122 may be formed in a shape corresponding to an arrangement of the magnetic field generators 121.

Referring again to FIG. 4, for example, when four magnetic field generators 121 are disposed, the support plate 122 may be formed in an approximate cross shape such that the four magnetic field generators 121 are disposed. Accordingly, even when the support plate 122 is positioned adjacent to an eyeball of a patient to perform corneal endothelial transplantation, the support plate 122 may hardly block a field of view of a user or a field of view of the imaging module 150. In addition, the weight of the support plate 122 may be reduced, which may make it easier to perform corneal endothelial transplantation or to move and operate the magnetic field generation module 120.

In an alternative embodiment, the support plate 122 may include the surgical port 1221 for observing the tissue carrier 110. The surgical port 1221 may be formed to pass through the support plate 122. That is, the surgical port 1221 may be a hole drilled in the support plate 122. Therefore, during surgery, a user may observe a surgery scene with the naked eye through the surgical port 1221. In addition, the imaging module 150 may acquire a surgery image by photographing a surgery scene through the surgical port 1221.

As a specific embodiment, referring again to FIG. 4, when the plurality of magnetic field generators 121 are disposed, the surgical port 1221 may be formed at a central portion of the plurality of magnetic field generators 121. To this end, the plurality of magnetic field generators 121 may be disposed along a circumference of the surgical port 1221, and specifically, the plurality of magnetic field generators 121 may be disposed in a direction toward the surgical port 1221.

Through such an arrangement, when a user operates the user input module 140 to move the tissue carrier 110, the magnetic field generator 121 may generate a magnetic field, and the generated magnetic field may be concentrated in the direction toward the surgical port 1221. In addition, since the plurality of magnetic field generators 121 are disposed along the circumference of the surgical port 1221, a magnetic field generated by an input of a user may move the tissue carrier 110 in a width direction of the support plate 122 in FIG. 4.

As an alternative embodiment, the support plate 122 may further include a flat portion 1222 extending from one side. The flat portion 1222 may be formed in a plate shape having a width.

As an embodiment, a circuit board may be disposed on the flat portion 1222.

Meanwhile, the flat portion 1222 may be a portion gripped by a user. For example, in order to perform corneal endothelial transplantation, while gripping the flat portion 1222, the user may move the magnetic field generation module 120 to a position adjacent to an eyeball of a patient.

In addition, while gripping the flat portion 1222, the user may move the magnetic field generation module 120 in a direction perpendicular to the width direction of the support plate 122. Accordingly, a magnetic field applied to the tissue carrier 110 may be adjusted in the direction perpendicular to the width direction of the support plate 122.

That is, assuming that the width direction of the support plate 122 corresponds to an xy plane, the user may operate the user input module 140 to perform control such that a direction of a magnetic field applied to the tissue carrier 110 is directed in x-axis and y-axis directions. By gripping the flat portion 1222, the user may move the magnetic field generation module 120 in a z-axis direction to perform control such that the direction of the magnetic field applied to the tissue carrier 110 is directed in the z-axis direction.

Referring again to FIGS. 5 and 6, the magnetic field generator 121 will be described in more detail.

As an embodiment, the magnetic field generator 121 may be disposed to be inclined in a direction toward the tissue carrier 110. For example, the magnetic field generator 121 may be formed to be inclined in the direction toward the surgical port 1221.

To this end, the magnetic field generation module 120 may further include a support 123 for supporting the magnetic field generator 121, and the number of supports 123 may correspond to the number of magnetic field generators 121.

The support 123 may be coupled to a biased position at one side of the magnetic field generator 121. Therefore, referring again to FIG. 5, the magnetic field generator 121 may be inclined such that one side to which the support 123 is coupled is positioned at a relatively higher level than the other side.

Since the magnetic field generator 121 is disposed to be inclined in this way, the plurality of magnetic field generators 121 may be inclined in the direction toward the surgical port 1221, and a magnetic field may be concentrated in the direction toward the surgical port 1221.

In addition, since the human eyeball is formed in an approximately spherical shape, the human eyeball includes a portion that protrudes convexly toward the outside of an eye. Therefore, in this way, when the magnetic field generator 121 is inclined in the direction toward the surgical port 1221 to concentrate a magnetic field, the tissue carrier 110 may be moved more precisely and efficiently.

The magnetic field generator 121 may include the coil, the core 1211, and a body 1212. As described above, the coil may be wound along the outer circumference surface of the core 1211 and may be a component through which a current supplied from a power source flows. Therefore, when a current flows through the coil, a magnetic flux is induced on the core 1211, and a magnetic field may be generated along the core 1211.

The body 1212 may be a component that constitutes a body of the magnetic field generator 121. The core 1211 may be disposed to pass through at least a portion of the body 1212. For example, at least a portion of the core 1211 may be disposed inside the body 1212. In addition, at least a portion of the core 1211 may be formed to extend outward from the body 1212. In this case, the portion of the core 1211 that extends outward from the body 1212 may be at a position close to the surgical port 1221.

Accordingly, a magnetic field generated from the magnetic field generator 121 may be generated to ultimately pass through a portion of the core 1211 exposed to the outside of the body 1212, that is, one end of the core 1211 close to the surgical port 1221, to be concentrated in the direction toward the surgical port 1221. Accordingly, the magnetic field generated from the magnetic field generator 121 may be concentrated in the direction toward the surgical port 1221.

As an alternative embodiment, the core 1211 may include at least one curved portion 1213 and an inclined portion 1214. For example, the core 1211 may include the curved portion 1213 bent at a certain angle in the direction toward the tissue carrier 110, and the inclined portion 1214 inclined in the direction toward the tissue carrier 110.

The curved portion 1213 may be a portion bent among portions of the core 1211. Specifically, the curved portion 1213 may be formed at the portion of the core 1211 exposed to the outside of the body 1212, and the core 1211 may be formed to be bent in the direction toward the surgical port 1221. Specifically, referring again to FIG. 6, the portion of the core 1211 exposed to the outside of the body 1212 may be bent in a downward direction of the curved portion 1213, that is, in the direction toward the surgical port 1221. Accordingly, when the magnetic field generation module 120 is positioned adjacent to an eyeball of a patient, the core 1211 may be bent at a certain angle in the direction toward the tissue carrier 110.

In addition, the plurality of magnetic field generators 121 may each include the core 1211, and each core 1211 may include the curved portion 1213.

Accordingly, a magnetic field generated from the plurality of magnetic field generators 121 may be more efficiently concentrated in the direction toward the surgical port 1221.

The inclined portion 1214 may be a portion formed to be inclined at an end portion among the portions of the core 1211. Specifically, the inclined portion 1214 may be formed at the end portion of the core 1211 and may be formed at an end portion of the portion exposed to the outside of the body 1212. In this case, the inclined portion 1214 may be formed to have a cross section similar to a hyperbola formed by obliquely cutting a cylinder. In this case, as shown in FIG. 6, the inclined portion 1214 may be formed to be inclined in the direction toward the surgical port 1221.

In addition, the plurality of magnetic field generators 121 may each include the core 1211, and each core 1211 may include the inclined portion 1214.

Accordingly, a magnetic field generated from the plurality of magnetic field generators 121 may be more efficiently concentrated in the direction toward the surgical port 1221.

FIG. 7 is a schematic view illustrating a process of attaching CET to a cornea.

Referring to FIGS. 2 and 7, the corneal endothelial tissue transplantation system 100 according to an embodiment of the present disclosure may further include an air supply module 170.

The air supply module 170 may be a means for supplying air to the inserted tissue carrier 110 to move the CET attached to the tissue carrier 110 to be closer to a cornea.

Specifically, the air supply module 170 may supply air to the tissue carrier 110 to which the CET is attached, thereby moving the tissue carrier 110 upward in FIG. 7. Accordingly, the CET may attach to a corneal endothelium by moving upward together with the tissue carrier 110.

Thereafter, after the CET is attached to the cornea to a certain extent or more, a user may separate a wire attached to the tissue carrier 110 and may remove only the wire from an AC of an eyeball.

By including a configuration described above, according to the corneal endothelial tissue transplantation system 100 according to the present disclosure, there may be provided the corneal endothelial tissue transplantation system 100 capable of easily and precisely manipulating CET without inserting a separate tool into an AC of an eyeball.

In addition, according to the corneal endothelial tissue transplantation system 100 including such a configuration, a magnetic field may be efficiently concentrated in the direction toward the inserted tissue carrier 110, thereby improving the operation precision of a user.
