Description

Technical Field

[0001] The utility model relates to the field of corneal collagen cross-linking surgery, in particular to a riboflavin soaking device used in the corneal collagen cross-linking surgery. Background Art

[0002] Corneal collagen cross-linking is a surgical procedure that delays the progression of keratoconus by increasing corneal hardness and stability. The procedure uses riboflavin as a photosensitizer and uses ultraviolet radiation of a special wavelength and dose to cause corneal collagen to undergo a cross-linking reaction, thereby increasing corneal hardness. The procedure mainly includes two steps: riboflavin soaking and ultraviolet radiation. Riboflavin soaking is to drip riboflavin onto the patient's cornea and soak it for a certain period of time so that it fully penetrates into the corneal collagen. This step is an important step to ensure the effectiveness of the surgery.

[0003] At present, riboflavin soaking has the following problems: 1. If the riboflavin soaking device is not used, the doctor needs to frequently drip riboflavin on the corneal surface, resulting in a large amount of riboflavin waste, and it is not easy to form pressure on the corneal surface to promote penetration, prolonging the operation time and reducing the operation efficiency. 2. If the riboflavin soaking device is used, it can prevent riboflavin from flowing out of the eye, avoiding riboflavin waste and improving the operation efficiency; however, the riboflavin soaking device currently used clinically still has the problem of weak adsorption and easy loosening of the eyeball when the patient rotates. After loosening, the soaking device needs to be re-placed and riboflavin needs to be dripped, which will also prolong the operation time and cause riboflavin waste, and increase the patient's discomfort and psychological anxiety.

[0004] How to invent a riboflavin soaking device for use in corneal collagen cross-linking surgery to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

When the patient subconsciously turns the eyeball due to discomfort and instinctive reaction, the ring body will also move with the eyeball, and there will be no misalignment between the ring body and the patient's cornea, thereby avoiding the outflow and waste of riboflavin. At the same time, the overall adsorption force of the ring body can be adjusted according to actual conditions and needs, reducing limitations in use and improving stability.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a riboflavin immersion device used in corneal collagen cross-linking surgery, comprising an immersion ring 1, the immersion ring 1 comprises a ring body 101, an inwardly recessed negative pressure groove 102 is provided on the bottom surface of the ring body 101, a connecting hole seat 103 is provided on the inner wall of one side of the negative pressure groove 102, one end of the connecting hole seat 103 is connected to a negative pressure regulating handle 2, the negative pressure regulating handle 2 comprises a connecting pipe 201, one end of the connecting pipe 201 is connected to the connecting hole seat 103, a sealing piston 206 is provided in the connecting pipe 201, and the sealing piston 206 is connected to the regulating mechanism.

[0023] See also Figure 2 and Figure 3 Corresponding silicone sealing rings 104 are fixedly connected to the edges of both sides of the bottom opening of the negative pressure groove 102.

[0024] By arranging silicone sealing rings 104 on both side edges of the bottom opening of the negative pressure groove 102, the fit between the edge of the negative pressure groove 102 and the eyeball 3 can be improved, so as to achieve a more stable sealing. When the inside of the negative pressure groove 102 is adjusted to a negative pressure environment through the negative pressure adjustment handle 2, the ring body 101 as a whole can be adsorbed on the patient's eyeball 3. At the same time, the silicone material is relatively soft, which can also reduce the patient's discomfort during the operation.

[0025] Furthermore, the edges on both sides of the bottom opening of the negative pressure groove 102 are arranged with a height difference, and the outer edge extends longer than the inner edge.

[0026] By setting the two side edges of the bottom opening of the negative pressure groove 102 to an angled bevel, it can be more adapted to the shape of the eyeball 3, thereby further ensuring the fit between the bottom opening of the ring body negative pressure groove 102 and the eyeball 3, and thus improving the sealing performance under negative pressure.

[0027] See also Figure 3 and Figure 4 The connecting pipe 201 is externally sleeved with a sleeve 202, the outer wall of the connecting pipe 201 is provided with a thread 203, the inner wall of the sleeve 202 is provided with a thread groove 204 corresponding to the thread 203, the connecting pipe 201 and the sleeve 202 are threadedly connected with the thread groove 204 through the thread 203, one end of a connecting rod 205 is rotatably mounted on the inner wall of one end of the thread groove 204, and the other end of the connecting rod 205 is fixedly connected to the sealing piston 206.

[0028] When in use, the sleeve 202 can be rotated to achieve independent displacement relative to the connecting tube 201, and the sealing piston 206 can be driven by the connecting rod 205 to perform synchronous displacement in the connecting tube 201, so that the air in the negative pressure groove 102 is drawn into the connecting tube 201, and the volume is expanded and the air content is reduced under the condition of the same air content, so that the negative pressure groove 102 enters a negative pressure state and the ring body 101 is adsorbed on the patient's eyeball 3 as a whole, which can avoid the patient's subconscious rotation of the eyeball 3 during the operation without causing dislocation relative to the ring body 101, thereby reducing the waste of drugs.

[0029] Furthermore, the diameter of the sealing piston 206 corresponds to the inner diameter of the connecting pipe 201 .

[0030] The diameter of the sealing piston 206 corresponds to the inner diameter of the connecting pipe 201, thereby ensuring air tightness when extracting air and providing stability for use.

[0031] Furthermore, the sealing piston 206 is located closer to the ring body 101 relative to the opening at one end of the sleeve 202, and the connecting tube 201 is made of a transparent material.

[0032] The sealing piston 206 is positioned protruding from the opening at one end of the sleeve 202, and the connecting tube 201 is made of a transparent material. Therefore, when the sleeve 202 drives the sealing piston 206 to move outward to extract the air in the negative pressure groove 102, the user can intuitively see the specific position of the sealing piston 206 inside the connecting tube 201, and thus can adjust the negative pressure value in the negative pressure groove 102 according to actual conditions and needs, thereby achieving the ability to adjust the overall adsorption force of the ring body 101 and reduce limitations in use.

[0033] Furthermore, a negative pressure scale mark is provided on the inner wall of the connecting pipe 201 .

[0034] By setting negative pressure value scale marks on the inner wall of the connecting pipe 201, the negative pressure situation inside the negative pressure tank 102 at this time can be more intuitively understood by observing the position of the sealing piston 206 and the corresponding negative pressure value marks, thereby improving practicality during use.

[0035] Furthermore, a plurality of anti-slip grooves 207 evenly distributed in an annular shape are formed on the outer wall of the sleeve 202 .

[0036] By providing an anti-slip groove 207 on the outside of the sleeve 202, the user can avoid slipping when turning the sleeve 202 when his hands are wet or he is wearing gloves, so that the negative pressure value inside the negative pressure tank 102 can be accurately adjusted to provide stability for use. At the same time, the connecting tube 201 and the sleeve 202 can both be made of medical plastic material to reduce the overall weight, thereby reducing the feeling of falling when adsorbed onto the patient's eyeball 3.

[0037] Working principle: When in use, the ring body 101 is placed as a whole on the patient's eyeball 3, so that the hole in the middle of the ring body 101 corresponds to the position of the patient's cornea, and the ring body 101 is lightly pressed to make the silicone sealing ring 104 set on the two side edges of the bottom end of the negative pressure groove 102 completely fit on the patient's eyeball 3, and the sleeve 202 can be rotated to achieve its independent displacement relative to the connecting tube 201, and the sealing piston 206 can be driven by the connecting rod 205 to perform synchronous displacement in the connecting tube 201, so that the air in the negative pressure groove 102 is drawn into the connecting tube 201, and the volume is expanded and the air content is reduced under the same air content, so that the negative pressure groove 102 enters a negative pressure state to adsorb the ring body 101 as a whole on the patient's eyeball 3, so that when the patient subconsciously rotates the eyeball 3 during the operation, it will not cause dislocation relative to the ring body 101, thereby reducing the waste of riboflavin.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
