Description

Technical Field

[0001] This utility model relates to the field of ophthalmic surgery technology, specifically to an artificial pouch for ophthalmic surgery. Background Technology

[0002] In traditional cataract surgeries, when lens dislocation occurs, the entire lens and capsular bag are typically removed first, followed by a second-stage intraocular lens (IOL) implantation at a later date. Current methods primarily involve suture fixation and interlaminar fixation, but both rely heavily on three-piece IOLs made of polymethyl methacrylate (PMMA), which suffer from drawbacks such as poor refractive power, rigid lens material, and large surgical incisions. Furthermore, the poor positional stability of the implanted lens prevents the use of astigmatic or multifocal IOLs, significantly limiting patient options and hindering the achievement of good postoperative visual quality. Therefore, it is necessary to develop an artificial capsular bag that can be implanted simultaneously with lens and capsular bag removal during the first-stage surgery. After the surgical wound heals and intraocular inflammation stabilizes, a common hydrophobic or hydrophilic acrylic IOL can be directly implanted into the capsular bag during the second-stage surgery, providing more options for both patients and surgeons and improving postoperative visual quality. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide an artificial capsule for ophthalmic surgery, which has a simple structure, better suture fixation stability, and facilitates improved postoperative visual quality for patients.

[0004] To achieve the above objectives, this utility model proposes an artificial pouch for ophthalmic surgery, which includes: a pouch body;

[0005] The entire capsule body is made of hydrophobic acrylic material with a refractive power of 0. The capsule body has a cavity and a connecting part. The cavity is a hollow flattened sphere with a circular opening that allows the crystal to be placed inside the cavity. The connecting part is connected to the periphery of the cavity and has a connecting hole. The periphery of the connecting hole is made of polymethyl methacrylate material.

[0006] According to an embodiment of the present invention, an artificial capsule for ophthalmic surgery is made entirely of hydrophobic acrylic material with a refractive power of 0. This facilitates the folding and insertion of the capsule body, along with the intraocular lens, into the posterior chamber of the eyeball, confining the intraocular lens within the capsule cavity and not affecting the intraocular lens measurement during secondary surgery. The periphery of the connecting hole in the connecting part is made of polymethyl methacrylate material, which improves the stability of suture fixation. This artificial capsule for ophthalmic surgery has a simple structure, better suture fixation stability, and facilitates improved postoperative visual quality for patients.

[0007] In addition, the artificial pouch for ophthalmic surgery proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] Optionally, the diameter of the opening of the cyst cavity is 4.8 mm to 5 mm.

[0009] Optionally, the diameter of the connecting hole is 0.8 mm to 1 mm.

[0010] Optionally, the diameter of the cyst cavity is 9 mm to 10 mm.

[0011] Optionally, the connecting portion has three parts, which are spaced apart on the outer edge of the cyst cavity, and all three parts are arranged in a triangular shape.

[0012] Optionally, the maximum height of the cyst cavity is 2.8 mm to 3 mm. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] The following is for reference. Figures 1-3 The present invention describes in detail the implementation of an artificial pouch for ophthalmic surgery according to an embodiment of the present invention.

[0022] An artificial bag for ophthalmic surgery according to an embodiment of the present invention includes: a bag body 1.

[0023] Specifically, the capsule body 1 is made entirely of hydrophobic acrylic material with a refractive power of 0. The capsule body 1 has a cavity 11 and a connecting part 12. The cavity 11 is a hollow flattened spherical shape and has a circular opening 111 that can be placed into the cavity 11. The connecting part 12 is connected to the periphery of the cavity 11 and has a connecting hole 121. The periphery of the connecting hole 121 is made of polymethyl methacrylate material.

[0024] In other words, because hydrophobic acrylate is stretchable, it is easy to fold the capsule body 1. When the artificial lens 2 is implanted into the capsule cavity 11, due to the stretching effect of the artificial lens, the inner wall of the capsule cavity 11 will have a clamping force towards the artificial lens 2, which is beneficial to the stability of the artificial lens 2. The refractive power of the capsule body 1 is set to 0, which is convenient for the measurement of the artificial lens 2 during the second-stage surgery. The periphery of the connecting hole 121 of the connecting part 12 is made of polymethyl methacrylate, which is convenient to improve the strength of the connecting hole 121, thus making it more stable when the suture is fixed.

[0025] Therefore, since the entire capsular body 1 is made of hydrophobic acrylic material with a refractive power of 0, it is easy to fold the capsular body 1 together with the artificial lens 2 and place it into the posterior chamber of the eyeball 3, thus confining the artificial lens 2 within the capsular cavity 11 and not affecting the measurement of the artificial lens 2 during the second-stage surgery. The periphery of the connecting hole 121 of the connecting part 12 is made of polymethyl methacrylate material, which improves the stability of suture fixation. This artificial capsular structure for ophthalmic surgery is simple, has better suture fixation stability, and facilitates the improvement of the patient's postoperative visual quality.

[0026] Optionally, the diameter of the opening 111 of the capsule 11 is 4.8 mm to 5 mm. Understandably, with the above configuration, most intraocular lenses 2 used in clinical practice can be inserted through the opening 111. The opening 111 of the capsule 11 can be located in the center of the capsule 11, and the diameter of the opening 111 can be 5 mm.

[0027] Optionally, the diameter of the connecting hole 121 is 0.8 mm to 1 mm. Understandably, this design facilitates compatibility with most sutures used in clinical practice. The diameter of the connecting hole 121 can be 1 mm.

[0028] Optionally, the diameter of the capsule 11 is 9mm to 10mm. Understandably, this design facilitates conformity to the original anatomical structure of the human lens. The diameter of the capsule 11 can be 10mm.

[0029] Optionally, there are three connecting portions 12, which are spaced apart on the outer edge of the capsule 11 and are all triangular in shape. Understandably, this arrangement facilitates stable sutures to the posterior chamber of the eyeball 3. The distance from the connecting hole 121 to the outer periphery of the capsule 11 can be 3 mm, and the three connecting portions 12 can be arranged at non-uniform intervals.

[0030] Optionally, the maximum height of the capsule 11 is 2.8mm to 3mm. Understandably, this setting facilitates matching the thickness of most intraocular lenses 2 used in clinical practice. When the intraocular lens 2 is implanted into the capsule 11, the intraocular lens 2 stretches the inner wall of the capsule 11, allowing the inner wall of the capsule 11 to clamp the intraocular lens 2. This results in more precise positioning of the intraocular lens 2, which is beneficial for improving the patient's postoperative visual quality. The maximum height of the capsule 11 can be 3mm.
