Description

Implant device for ophthalmic disease with easy shape and physical properties change {MODIFIABLE-TRANSFORMABLE AND MATERIAL-TRANSFERRABLE OCULAR DISEASE IMPLANT APPARATUS}

The present invention relates to an implant device for ophthalmic diseases that can be easily changed in shape and physical properties, and more particularly, to an implant device customized for a patient in the form of a membrane that can be easily replaced with a shape and physical properties suitable for the eye condition and condition of a patient.

For patients with glaucoma whose intraocular pressure cannot be controlled even with intraocular pressure-lowering drugs, it lowers the intraocular pressure by creating a detour so that the aqueous humor from the anterior chamber of the eye flows under the conjunctiva outside the eye. Glaucoma filtration, which creates a bypass or fistula for aqueous humor outflow, may fail to control intraocular pressure due to decreased aqueous humor outflow due to occlusion of the bypass again after surgery. If the primary operation fails and glaucoma filtration is performed again, the frequency of bypass obstruction after surgery increases and the surgical success rate is poor.

In addition, depending on the type of glaucoma, even in the case of so-called intractable glaucoma, such as neovascular glaucoma or secondary glaucoma caused by uveitis, bypass obstruction is frequent after glaucoma filtration, resulting in poor results.

As such, in the case of an eye with a history of unsuccessful glaucoma filtration surgery or intractable glaucoma, a glaucoma implant device is operated to prevent bypass obstruction and increase the surgical success rate. The glaucoma implant device is made up of a tube in the anterior chamber of the eye that serves as a passageway for aqueous humor to exit the eye, and a small disc or membranous artifact that creates space for aqueous humor to temporarily collect under the subconjunctival or Tenon's capsule outside the eye.

Because conventional glaucoma implant devices are manufactured with a certain shape and physical properties and inserted into the eyeball, the implant device can be modified according to the patient's ocular condition or condition (ex. fibrosis progression rate, etc.) No, there is a problem that an effective waterproof outflow cannot be made due to this.

When the implant device for ophthalmic disease according to an embodiment of the present invention is inserted, one side of the tube 100 is inserted into the anterior chamber of the eyeball 10 and the tube 100 and the tube 100 are inserted into the combined implant body. 200 may be inserted into the conjunctival tissue or Tenon tissue (4). When the implant device is inserted, the aqueous humor generated in the anterior chamber may be temporarily accommodated in the implant body 200 by flowing through the tube 100 . When the amount of aqueous humor accommodated in the implant body 200 exceeds a certain amount, the received aqueous humor may be discharged to the conjunctival tissue or the Tenon tissue 4 through the rear of the implant body 200 . In this way, the intraocular pressure can be effectively controlled. Details regarding the specific form of the implant device will be described later in more detail with reference to FIGS. 2 to 4 .

2 is a perspective view of an implant device for eye disease according to an embodiment of the present invention.

Referring to FIG. 2 , the implant device for ophthalmic disease, which can be easily changed in shape and physical properties, according to an embodiment of the present invention, has a hollow formed therein for the outflow of aqueous humor, and a tube 100 and a tube 100 that can be inserted into a plate. ) in the form of a cover to prevent exposure of the upper plate 210 and the tube 100 in the form of a gutter on which the tube insertion path 221 is seated and the tube insertion path 221 to accommodate the waterproofing. It includes an implant body 200 including a lower plate 220 including a circular chamber 222 formed in the center, and the upper plate 210 may be detachably attached to the lower plate 220 .

One side of the tube 100 according to an embodiment of the present invention is located in the front of the eyeball 10 , and the other side is inserted through the tube insertion path 221 formed in the lower plate 220 to the center of the implant body 200 . (ie the circular chamber 222). As such, since the tube 100 is inserted into the implant body 200 , a separate donor tissue is not required, and the risk of exposure of the tube 100 can be reduced.

According to an embodiment of the present invention, since the upper plate 210 is detachable from the lower plate 220 , when the upper plate 210 is separated from the lower plate 220 , the tube 100 is stably attached to the lower plate 220 . ) can be seated in the tube insertion path (221). When the tube 100 is seated, the upper plate 210 may be reattached to the lower plate 220 to position the tube 100 to be completely fixed to the implant body 200 . The insertion method of the tube 100 through the attachment and detachment of the plate can completely improve problems such as the tube 100 being damaged or damaged in the process of inserting the tube 100 into the membrane plate, and the patient's eye condition Alternatively, the tube 100 having an appropriate length and width may be stably replaced and used according to conditions (eg, the patient's eye circumference, length, etc.). A method of attaching and detaching the upper plate 210 and the lower plate 220 will be described later in detail with reference to FIG. 4 .

According to an embodiment of the present invention, the width of the tube insertion path 221 in the form of a gutter on which the tube 100 is seated may be equal to or greater than the outer diameter of the tube 100 . That is, even when the diameter of the tube 100 needs to be larger depending on the eye condition or condition of the patient during surgery for the insertion of the implant device, only the tube 100 can be easily replaced without the need to replace the implant body 200 itself. In order to make it possible, the width of the tube insertion path 221 may be the same as the outer diameter of the tube 100 or may be formed larger than the outer diameter of the tube 100 . For example, the horizontal width of the tube insertion path 221 may preferably be a value of 0.4 mm, and the depth (i.e. vertical width) may be a value of 0.3 mm, but is not limited thereto.

The length of the tube 100 according to an embodiment of the present invention may preferably be a value of 30 mm, but may be formed to have a value in the range of 20 mm to 40 mm according to the circumferential length of the eyeball 10 . In addition, the inner diameter of the hollow tube 100 is formed to have a value in the range of 0.13mm to 0.23m, the outer diameter of the tube 100 may be formed to have a value in the range of 0.25mm to 0.4mm. When the tube 100 is formed with the same length and diameter as described above, the perforation window is small to minimize the amount of outflow around the waterproofing. In addition, through this, it is possible to reduce the number and types of post-operative treatment and the number of patients with initial complications after surgery.

The circular chamber 222 included in the lower plate 220 according to an embodiment of the present invention may be formed in a hemispherical shape partially recessed in the lower plate 220 or in a well shape. That is, since the circular chamber 222 is a space for temporarily accommodating the waterproofing, it is partially recessed in the lower plate 220 in a hemispherical shape or a well shape (ie a cylindrical shape) to effectively perform this role. can be In this case, the horizontal width of the circular chamber 222 may be preferably a value of 2 mm, and the depth (i.e. vertical width) of the circular chamber 222 may preferably be a value of 0.3 mm, but is not limited to the above-described example. When the aqueous humor is completely accommodated in this type of circular chamber, the upper plate 210 may inflate until it exceeds the maximum capacity, and when it exceeds the maximum capacity, the aqueous humor can be discharged to the conjunctival tissue or Tenon tissue (4). With respect to the discharge process of the aqueous humor, it will be described later in detail with reference to FIG. 6 .

The upper plate 210 according to an embodiment of the present invention may be formed in the form of an inflatable membrane in order to prevent exposure and separation of the tube 100 and at the same time to stably accommodate the waterproofing. More specifically, in relation to the stable reception of the aqueous humor, the upper plate 210 may be formed in a membrane form that can inflate when the aqueous humor is completely accommodated in the circular chamber in order to increase the aqueous waterproofing capacity of the implant body 200. . That is, the maximum storage capacity of the water can be determined according to the degree of expansion of the upper plate 210 formed in the form of a membrane.

The size of the upper plate 210 according to an embodiment of the present invention is formed to be equal to or smaller than the size of the lower plate 220 , and the thickness of the upper plate 210 is equal to or smaller than the thickness of the lower plate 220 . It can be formed thin. For example, referring to FIG. 2 , the size and thickness of the upper plate 210 may be smaller and thinner than the lower plate 220 . In this case, the thickness of the upper plate 210 may be a value of 0.2 mm, and the thickness of the lower plate 220 may be a value of 0.4 mm. As such, when the thickness of the upper plate 210 is formed thinner than the lower plate 220 , the lower plate 220 stably receives the aqueous humor through the circular chamber 222 while the aqueous humor is introduced into the implant body 200 . It can be accommodated, and the upper plate 210 can be easily expanded compared to the lower plate 220 . Through this, it is possible to effectively control the amount of outflow of the waterproofing water.

The upper plate 210 according to an embodiment of the present invention may be formed of a flexible material coated with an anti-fibrotic component on the outer surface or a flexible material containing an anti-fibrotic component. When the implant device is inserted into the eyeball 10, fibrosis occurs in the tissue of the inserted portion, which may cause damage such as the tube 100 or the implant body 200 being broken or crushed. When the tube 100 or the implant body 200 is damaged, the outflow and control function of the aqueous humor cannot be properly performed. or an anti-fibrotic component may be contained in the upper plate 210 .

In addition, since the upper plate 210 may be formed in the form of an expandable film, it may be formed of a flexible material such as silicon. Such a flexible material may vary depending on the eye condition or condition of the patient. That is, by changing the flexible material of the upper plate 210 according to the eye condition or condition of the patient, an implant device suitable for the patient's body can be provided. It is preferable that the upper plate 210 with a high risk of damage is formed as described above, but the lower plate 220 may also be formed of a flexible material containing an anti-fibrotic component like the upper plate 210 .

3 and 4 , on the surface 220-1 of the lower plate 220 in contact with the upper plate 210 according to an embodiment of the present invention, there is a protrusion for strengthening the bonding force with the upper plate 210 . can be formed. As shown in FIG. 3, the contact surface of the upper plate 210 and the lower plate 220 is a surface where the upper plate 210 and the lower plate 220 contact each other in structure, or as shown in FIG. 4, the upper plate 210 and the lower plate ( 220 may be a surface of the coupling portion 225 formed on the lower plate 220 for attachment and detachment between the plates, including surfaces that abut against each other in structure. The protrusions formed on the surface 220-1 of the lower plate 220 as in the above example form a rough surface to increase the contact friction force between the plates, and as the contact friction force increases, the upper plate 210 and the lower plate The coupling force between the 220 may be strengthened.

Referring to FIG. 4 , the upper plate 210 and the lower plate 220 according to an embodiment of the present invention may include coupling portions 212 and 225 for attaching and detaching each other. For example, the first coupling part 212 of the upper plate 210 may be formed in a protruding shape along the outer circumferential surface of the top plate 210 , and the second coupling part 225 of the lower plate 220 may have an upper portion. It may be formed in a recessed shape at a position corresponding to the first coupling portion 212 of the plate 210 . That is, the coupling portions 212 and 225 may be formed in a concave-convex shape to enable attachment and detachment between the plates. In addition, the first coupling part 212 of the upper plate 210 is inserted into the second coupling part 225 of the lower plate 220 in a form extending on the left and right sides of the upper plate 210 (eg, in the form of wings). can be formed.

3 and 4, the lower plate 220 according to an embodiment of the present invention is connected to the circular chamber 222 in order to assist the outflow of the aqueous humor, a plurality of possible formation in the rear of the lower plate 220. It may include a dog discharge path 223 . The discharge path 223 is a passage for stably flowing out the aqueous humor when the maximum capacity of the aqueous humor of the implant body 200 is exceeded, and may be formed in various shapes depending on the structure of the internal space of the upper plate 210 . can For example, as shown in FIG. 3, it may be connected to the circular chamber 222 and spread out to the rear of the lower plate 220, and as shown in FIG. 4, it is connected to the circular chamber 222 and the lower plate 220. It can be formed in a parallel form from a predetermined point while spreading to the rear of the . In this case, the width of the discharge path 223 may be preferably a value of 1 mm, and the depth of the discharge path 223 may be a value of 0.2 mm, but is not limited thereto.

In addition, referring to FIGS. 3 and 4 , the discharge path 223 according to an embodiment of the present invention has a plurality of discharge paths 223 in order to stably flow out even if one discharge path 223 is blocked or damaged due to fiberization, etc. can be formed with Since the discharge path 223 is formed in the lower plate 220 , when the upper plate 210 is smaller in size than the lower plate 220 , the rear portion of the lower plate 220 is not covered by the upper plate 210 . may be exposed to the outside.

5 is a perspective view showing a state that the implant device for eye disease according to an embodiment of the present invention is inserted into the eyeball (10).

Referring to FIG. 5A , an enlarged stereoscopic view of the implant device inserted into the eyeball 10 according to an embodiment of the present invention can be confirmed. As described above, the aqueous humor of the anterior chamber can be accommodated in the implant body 200 by moving through the tube 100 , and when the upper plate 210 expands to exceed the maximum capacity, the discharge formed toward the rear of the implant body 200 . Eye waterproofing may be discharged through the furnace 223 .

Referring to FIG. 5 (b), the implant device for eye disease according to an embodiment of the present invention further includes a wick that can be drawn into the hollow of the tube 100 in order to control the outflow of aqueous humor, and the lower plate ( 220 may include a plurality of wick passages 224 that are connected to the circular chamber 222 for adjustment or removal of the wick and can be formed in at least one direction of the front or side of the lower plate 220 . In this case, the wick may be a non-absorbable surgical suture for surgery, and more preferably made of nylon or propylene material.

Conventionally, since the wick could be located only inside the implant body, the amount of outflow of aqueous humor had to be controlled by moving it back and forth or removing it from one side (ie, the front of the eyeball 10) from which the aqueous humor of the tube 100 was introduced, This created significant difficulties in controlling the wick.

In order to improve this difficulty, the implant device according to an embodiment of the present invention allows the wick to pass through the wick passage 224 through the circular chamber 222 by being inserted into one side of the tube 100 into which the aqueous humor is introduced. , the wick can be positioned outside the implant body 200 (ie, the conjunctival tissue or the Tenon tissue 4 of the eyeball 10), and the length adjustment or removal of the wick can be easily performed. . In order to allow the wick to be positioned on the outside of the implant body 200 as shown in (b) of FIG. 5 , the wick passage 224 may be formed toward the front of the lower plate 220, and not only the front but also the side. can be formed towards At this time, the width of the wick passage 224 may be preferably a value of 0.3 mm and a value of 0.2 mm, but is not limited thereto.

In addition, the wick according to an embodiment of the present invention may be exposed outside the eye through the wick passage 224 to facilitate control and removal by a clinician. In this case, if the conventional wick is used, a problem may occur in which the patient feels a severe foreign body feeling due to the wick passing through the inside of the eyeball and exposed to the outside. In order to solve this problem, the wick according to an embodiment of the present invention is such that the diameter decreases toward the distal end (ie the end in the outer eye direction) based on a predetermined point on the proximal end (ie, the inner side of the eyeball) side. can be designed For example, the wick may be designed to taper off in diameter starting at the proximal end and reaching the distal end. In addition, the wick may be designed to have a constant diameter from the proximal end to the wick passage 224 , and to gradually decrease in diameter from the point passing through the wick passage 224 . As described above, if the diameter of the wick is designed to gradually decrease in the direction of exposure to the outside of the eyeball, the foreign body sensation felt by the patient with the implant device inserted into the eye can be minimized.

Figure 6 is a side view showing the discharge process of the aqueous humor of the implant device for ophthalmic disease according to an embodiment of the present invention.

Referring to (a) of Figure 6, the tube 100 is inserted into the implant body 200, it can be confirmed the state before the aqueous humor is accommodated. The tube 100 can be easily inserted through the attachment and detachment of the upper plate 210 and the lower plate 220 , and can be inserted up to the hemispherical circular chamber 222 formed in the center of the lower plate 220 . The upper plate 210 may be formed to be thinner than the lower plate 220 to facilitate expansion. In addition, when the maximum capacity of the main water is exceeded, the discharge path 223 of the main water can pass through the discharge path 223, the vertical width (ie depth) is formed smaller than the tube insertion path 221. Able to know. That is, when the vertical width (ie depth) of the discharge path 223 is larger than the tube insertion path 221 , the amount of the aqueous solution flowing into the implant body 200 and being accommodated is greater than the amount of the aqueous solution flowing out through the discharge path 223 . Since the amount of eye water increases, the discharge path 223 should be formed smaller than the tube insertion path 221 in order to stably control the eye water.

Referring to FIG. 6B , it can be seen that the implant device is inserted into the eyeball 10 and the aqueous humor leaks out. As described above, the aqueous humor is introduced through the inlet of the tube 100 located in the front chamber and accommodated in the circular chamber 222, and the upper plate 210 can be expanded as the aqueous humor is accommodated. When the upper plate 210 expands and exceeds the maximum capacity, the aqueous humor may flow out to the conjunctival tissue or the Tenon tissue through the discharge path 223 formed toward the rear of the lower plate 220 . It is possible to effectively treat eye diseases, including glaucoma, by regulating intraocular pressure through this aqueous humor outflow process.

Referring to FIG. 6 , the upper plate 210 according to an embodiment of the present invention may include a well-shaped fixing part 211 that can be formed at one point of the upper plate 210 for the operation and fixation of the implant device. can In this case, the diameter of the fixing part 211 may preferably be a value of 0.5 mm, but is not limited thereto.

According to an embodiment of the present invention, after the implant device is inserted into the eyeball 10, the implant device is more stably inserted into the fixing part 211 of the well shape (ie cylindrical shape) in which the tissue is partially recessed in the fibrosis process. It may be fixed within the eyeball 10 . In addition, when the coupling of the upper plate 210 and the lower plate 220 is unstable or the implant device moves without being fixed in the eyeball 10, the fixing part 211 is penetrated by the clinician and the penetrating portion is used for surgery. It may be fixed with a thread or the like. That is, the fixing part 211 may be formed in the form of a well partially recessed in the plate so that the fixing part 211 can be selectively penetrated according to the implant device and the eye condition or condition of the patient.

The above-mentioned fixing part 211 may be formed not only on the upper plate 210 but also on the lower plate 220 . When the fixing part 211 is formed in the lower plate 220 , a through hole may be formed at a position of the upper plate 210 corresponding to the fixing part 211 formed in the lower plate 220 . The hole through the upper plate 210 is formed in this way so that the fixing part 211 of the lower plate 220 covered by the upper plate 210 can stably perform its function. At this time, the depth of the fixing part 211 including the depth of the hole may be a value of 0.5 mm (ie, the depth of the through hole is 0.2 mm, the depth of the fixing part 211 of the lower plate 220 is 0.3 mm), The present invention is not limited thereto.
