Abstract
Description
Technical Field
[0001] The present invention relates to the medical field, and in particular to a method for forming a stable simulation structure of the anterior capsule and a simulation training method for cataract surgery. Background Art
[0002] The description in this section merely provides background information related to the disclosure of this specification and does not constitute prior art.
[0003] Cataract surgery is a routine ophthalmic procedure with relatively mature technical solutions. However, one difficulty has plagued ophthalmologists both domestically and internationally: the "Argentine flag sign."
[0004] The lens capsule is a thin, transparent membrane that completely covers the surface of the lens. Its shape resembles a biconvex lens, with the anterior capsule convex forward and the posterior capsule convex backward. Continuous circular capsulotomy is a crucial step in cataract surgery. Forceps are used to tear a circular hole approximately 5 to 5.5 mm in diameter in the central region of the anterior capsule, forming an anterior capsule opening. The phacoemulsification needle is then inserted through the anterior capsule opening into the lens, pulverizing and aspirating the solid tissue within the lens (the lens cortex and nucleus).
[0005] In mild and moderate cataracts, the internal pressure of the lens is low, and the surgeon can successfully complete continuous circular capsulotomy. However, in mature and post-mature cataracts, the lens protein liquefies, resulting in increased osmotic pressure inside the lens. Water outside the lens capsule enters the lens, causing the pressure inside the lens to rise and the capsule tension to increase. When the capsule is torn, the capsule is under greater internal pressure and is prone to rupture rapidly toward the periphery. Subsequent surgical steps cannot be completed smoothly. In severe cases, it may even cause serious complications such as vitreous prolapse and inability to implant the intraocular lens normally, greatly reducing the patient's vision after surgery.
[0006] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of this specification and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this specification, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0009] Filling a simulated space with a viscoelastic agent; the simulated space is a space enclosed by a simulated cornea, a simulated iris, and a simulated anterior capsule;
[0010] An air bubble is injected into the viscoelastic agent; the front surface of the air bubble contacts the inner surface of the simulated cornea, and the rear surface of the air bubble contacts the simulated anterior capsule membrane; the simulated anterior capsule membrane includes a contact area in contact with the air bubble and a non-contact area not in contact with the air bubble, the non-contact area has a tendency to bulge forward, and the curvature of the contact area is smaller than the curvature of the non-contact area.

[0014] As a preferred embodiment, in the step of injecting air bubbles into the viscoelastic agent, the contact area is circular, the non-contact area is annular, and the non-contact area surrounds the contact area.
[0015] As a preferred embodiment, in the step of injecting air bubbles into the viscoelastic agent, the area of the contact zone is greater than or equal to one tenth of the total area of the simulated anterior capsule.
[0016] As a preferred embodiment, in the step of injecting air bubbles into the viscoelastic agent, the contact area is prevented from bulging forward under the pressure of the air bubbles.

[0040] See also Figure 1 The present application provides a method for forming a stable anterior capsule mimic structure, comprising the following steps:
[0041] Step S10: Filling the simulation space 11 with viscoelastic agent.
[0042] The simulated space 11 is a space enclosed by the simulated cornea 2 , the simulated iris 5 and the simulated anterior capsule 8 .
[0043] Step S20: injecting air bubbles 12 into the viscoelastic agent.
[0044] The front surface of the air bubble 12 contacts the inner surface of the simulated cornea 2, and the rear surface of the air bubble 12 contacts the simulated anterior capsule 8. The simulated anterior capsule 8 includes a contact area in contact with the air bubble 12 and a non-contact area not in contact with the air bubble 12. The non-contact area tends to bulge forward, and the curvature of the contact area is smaller than that of the non-contact area.
[0045] The method for forming a stable simulated structure of the anterior capsule provided in this embodiment fills the simulated space 11 with a viscoelastic agent and injects an air bubble 12 into the viscoelastic agent, so that the front surface of the air bubble 12 contacts the inner surface of the simulated cornea 2 and the back surface of the air bubble 12 contacts the simulated anterior capsule 8. This can make the curvature of the contact area of the simulated anterior capsule 8 smaller than the curvature of the non-contact area, thereby reducing the tension of the simulated anterior capsule 8 and preventing uncontrollable rupture of the simulated anterior capsule 8.
[0046] In this embodiment, the viscoelastic agent used in step S10 has high viscosity and is in a gel state.
[0047] like Figure 3 As shown, in step S20, an air bubble 12 is injected into the center of the viscoelastic agent so that the air bubble 12 is located in the middle (center) of the viscoelastic agent, thereby better reducing the tension of the simulated anterior capsule 8.
[0048] Preferably, in step S20, the front surface of the air bubble 12 is brought into contact with the central area of the inner surface of the simulated cornea 2. In step S20, the rear surface of the air bubble 12 is brought into contact with the central area of the simulated anterior capsule 8.
[0049] In this embodiment, in step S20, the contact area is circular, the non-contact area is annular, and the non-contact area surrounds the contact area. Preferably, the contact area is located at the center of the simulated anterior capsule 8.
[0050] In order to better achieve the effect of reducing the tension of the simulated anterior capsule 8 , in step S20 , the area of the contact region is made greater than or equal to one tenth of the total area of the simulated anterior capsule 8 .
[0051] In this embodiment, in step S20, the contact area is prevented from bulging forward under the pressure of the air bubble 12. Preferably, the surface of the contact area is maintained substantially flat, that is, the central region of the simulated anterior capsule 8 is flattened under the pressure of the air bubble 12, thereby effectively reducing the tension of the simulated anterior capsule 8 and preventing capsule rupture. Of course, the surface of the contact area can be pressed into a flat surface or a substantially flat surface. This application does not impose strict restrictions on the flatness of the contact area. The contact area only needs to be significantly less bulging forward than the non-contact area. Preferably, the curvature of the contact area is maintained close to zero.
[0052] like Figure 3 1 is a schematic structural diagram of an eyeball model 1 having an anterior capsule stabilization simulation structure. The anterior capsule stabilization simulation structure is formed using the method for forming an anterior capsule stabilization simulation structure provided in this embodiment.
[0053] Specifically, the eyeball model 1 also includes a transparent simulated cornea 2 located at the front and a porcelain-white opaque simulated sclera 3 located at the back. The simulated ciliary body 4 is located on the inner surface of the simulated sclera 3. The root of the simulated iris 5 (i.e., the peripheral portion of the simulated iris 5) is attached to the front of the simulated ciliary body 4, and the inner side of the front of the simulated ciliary body 4 has a simulated ciliary process 6 that protrudes inward. The simulated lens 7 is located behind the simulated iris 5. The surface of the simulated lens 7 is wrapped with a simulated capsule, the front of the simulated capsule is the simulated anterior capsule 8, and the back of the simulated capsule is the simulated posterior capsule 9. The peripheral portion of the simulated capsule is connected to the simulated ciliary process 6 via a simulated suspensory ligament 10. The simulated space 11 is the space enclosed by the simulated cornea 2, the simulated iris 5, and the simulated anterior capsule 8. The simulated space 11 can be called a simulated anterior chamber. Under normal circumstances, the simulated anterior chamber is filled with transparent liquid (i.e., simulated aqueous humor).
[0054] It should be noted that, in Figure 3In the first direction X shown, the side of the eye model 1 closer to the simulated cornea 2 is defined as "front," and the side of the eye model 1 farther from the simulated cornea 2 is defined as "back." This definition applies to the terms "front" and "back" used in this application. The method for forming a stable anterior capsule structure provided in the embodiments of this application can be used to demonstrate how to reduce internal lens pressure in mature and post-mature cataracts when the lens protein is liquefied. This can reduce the risk of capsule rupture during membrane tearing and avoid serious complications such as vitreous prolapse and failure to properly implant an intraocular lens.
[0055] It should be noted that Figure 3 The provided eyeball model 1 and the anterior capsule stabilization simulation structure formed by the method for forming the anterior capsule stabilization simulation structure provided in this embodiment are used to guide teaching or simulation training, for example, for interns or students to perform cataract surgery training or teaching; the anterior capsule stabilization simulation structure is a simulation structure within the eyeball model 1 and can also be used in the eyeballs of animals such as pigs and dogs. It should not be used in the human eyeball, has nothing to do with the human body, and does not belong to the diagnosis and treatment of diseases.
[0056] Based on the same concept, the present application also provides a cataract surgery simulation training method in the following embodiments, as described in the following embodiments. Since the principle of solving the problem and the technical effects that can be achieved by this cataract surgery simulation training method are similar to those of the above-mentioned method for forming a stable anterior capsule simulation structure, the implementation of this cataract surgery simulation training method can refer to the implementation of the above-mentioned method for forming a stable anterior capsule simulation structure, and the repeated parts will not be repeated.
[0057] like Figure 2 As shown, one embodiment of the present application further provides a cataract surgery simulation training method, comprising the following steps:
[0058] Step S10: Filling the simulation space 11 with viscoelastic agent.
[0059] The simulated space 11 is a space enclosed by the simulated cornea 2 , the simulated iris 5 and the simulated anterior capsule 8 .
[0060] Step S20: injecting air bubbles 12 into the viscoelastic agent.
[0061] The front surface of the air bubble 12 contacts the inner surface of the simulated cornea 2, and the rear surface of the air bubble 12 contacts the simulated anterior capsule 8. The simulated anterior capsule 8 includes a contact area in contact with the air bubble 12 and a non-contact area that does not contact the air bubble 12. The non-contact area has a forward convexity, and the curvature of the contact area is smaller than that of the non-contact area. A stable simulated anterior capsule structure is formed according to steps S10 and S20.
[0062] Step S30: continuous circular capsulorrhexis.
[0063] In step S30, a simulated anterior capsule opening is formed in the simulated anterior capsule. Because the air bubble 12 injected into the viscoelastic agent contacts the inner surface of the simulated cornea 2 with its anterior surface and contacts the simulated anterior capsule 8 with its posterior surface, the curvature of the contact area of the simulated anterior capsule 8 is smaller than the curvature of the non-contact area. This reduces the tension of the simulated anterior capsule 8 and prevents uncontrolled rupture of the simulated anterior capsule 8, thereby successfully completing the simulated continuous curvilinear capsulorrhexis.
[0064] In this embodiment, the implementation method of the cataract surgery simulation training method corresponds to the implementation method of the anterior capsule stabilization simulation structure forming method, which can solve the technical problems solved by the implementation method of the anterior capsule stabilization simulation structure forming method, and accordingly achieve the technical effects of the implementation method of the anterior capsule stabilization simulation structure forming method. The specific details of this application will not be repeated here.
[0065] Specifically, between step S20 and step S30, that is, after forming a stable simulated structure of the anterior capsule, a needle can be used to penetrate the center of the simulated anterior capsule 8 into the interior of the simulated lens 7 to remove a portion of the liquefied simulated cortex, thereby reducing the pressure inside the simulated lens 7 and allowing the simulated capsule to become more relaxed, so as to successfully complete the subsequent simulated continuous circular capsulotomy (step S30).
[0066] like Figure 2 Specifically, after step S30, the following steps may be further included:
[0067] Step S40: crushing and removing the solid tissue in the simulated lens.
[0068] Specifically, the phacoemulsification needle can be inserted into the simulated lens through the simulated anterior capsule to crush and remove the solid tissue inside the simulated lens. The solid tissue includes the lens cortex and the lens nucleus.
[0069] Step S50: Implanting a simulated intraocular lens.
[0070] like Figure 2 As shown, after step S50, step S60 is further included: using a suction needle to remove the air bubble 12 and the viscoelastic agent. This step can be used to conveniently and quickly remove the anterior capsule stabilization simulation structure formed by steps S10 and S20.
[0071] It should be noted that the anterior capsule stabilization simulation structure forming method and cataract surgery simulation training method provided in this embodiment are used to guide teaching or simulation training, for example, for interns or students to perform cataract surgery training or teaching; the anterior capsule stabilization simulation structure formed by the anterior capsule stabilization simulation structure forming method can be a simulation structure within the eyeball model 1 used for demonstration or teaching, etc. This method can be applied to the eyeballs of animals such as pigs and dogs, but should not be applied to human eyeballs, has nothing to do with the human body, and does not belong to the diagnosis and treatment of diseases.
[0072] It should be noted that, in the description of this specification, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this specification, unless otherwise specified, "plurality" means two or more.
[0073] Any numerical value cited herein includes all values of the lower and upper values in increments of one unit from the lower limit to the upper limit, and there is an interval of at least two units between any lower value and any higher value. For example, if the value of the quantity of a component or a process variable (such as temperature, pressure, time, etc.) is set forth to be from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification. For values less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be clearly expressed, and it can be considered that all possible combinations of the numerical values listed between the minimum and maximum values are explicitly set forth in this specification in a similar manner.
[0074] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. When used with a range, "about" or "approximately" applies to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the specified endpoints.
[0075] All articles and references disclosed herein, including patent applications and publications, are incorporated herein by reference for all purposes. The term "consisting essentially of..." when describing a combination should include the identified elements, ingredients, components, or steps and other elements, ingredients, components, or steps that do not materially affect the basic novel characteristics of the combination. The use of the terms "comprising" or "including" to describe a combination of elements, ingredients, components, or steps herein also contemplates embodiments consisting essentially of these elements, ingredients, components, or steps. By using the term "may," it is intended to indicate that any attribute described as "may" be optional.
[0076] Multiple elements, ingredients, components or steps can be integrated into a single element, ingredient, component or step.
[0077] Alternatively, a single integrated element, component, part or step may be divided into separate multiple elements, components, parts or steps. The disclosure "a" or "an" used to describe an element, component, part or step
[0078] It is not intended to exclude other elements, components, parts or steps.
[0079] It should be understood that the above description is for illustration and not for limitation. Many embodiments and applications other than the examples provided will be apparent to those skilled in the art upon reading the above description.
