Description

Technical Field

[0001] This invention belongs to the field of medical and health device technology and relates to a lens anterior and posterior capsule polisher. Background Technology

[0002] The lens cortex and lens nucleus are enclosed within the lens capsule. In phacoemulsification cataract surgery, after emulsifying and removing the lens nucleus and lens cortex using phacoemulsification technology, the anterior and posterior lens capsules need to be polished while preserving their integrity. This reduces the amount of residual lens cortex and lens epithelial cells adhering to these capsules. Polishing the anterior capsule reduces the probability of postoperative lens bag contraction, increasing the stability of the intraocular lens and the persistence of postoperative vision. Polishing the posterior capsule improves postoperative visual acuity and visual quality, and reduces the occurrence of recurrent cataracts (posterior capsule opacification) caused by residual cortex or lens epithelial cell proliferation.

[0003] The polishing methods for the anterior and posterior capsules are different. Polishing of the anterior capsule mainly relies on friction. During the operation, the doctor will use a special polishing instrument to remove the residual lens cortex and lens epithelial cells that adhere to it through the mutual friction between the instrument and the inner surface of the anterior capsule.

[0004] The posterior capsule is only 4 micrometers thick in its central part. It is mainly treated using the irrigation aspiration (IA) cortical handpiece attached to the phacoemulsification machine, achieved through the machine's low negative pressure and low flow rate. However, the negative pressure generated during polishing can still cause posterior capsule rupture. In recent years, water polishing has emerged. During cataract surgery, a blunt needle is inserted into the eye to flush the lens capsule, allowing water to wash the surface of the posterior capsule. However, the blunt needle can only spray a single jet of water tangentially towards the tip, limiting the area that can be flushed at once. Furthermore, the thin needle can still come into contact with the posterior capsule during use, causing rupture and reducing surgical safety. To avoid posterior capsule rupture, when using a blunt needle for water polishing of the posterior capsule, flushing is only performed near the incision site, without inserting it into the eye. While this improves safety, it also reduces the effectiveness of water polishing. Furthermore, existing techniques require two different instruments to polish the anterior and posterior capsules of the lens, increasing surgical costs. Frequent instrument changes during surgery also increase the number of surgical steps and the probability of complications. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides an anterior and posterior lens capsule polisher, thereby solving the technical problems that the existing anterior and posterior lens capsule polishing devices are separate devices, requiring frequent replacement during surgery, which is inconvenient to operate. In addition, the existing water polishing technology has a limited rinsing angle, small rinsing area, and low efficiency, and may come into contact with the posterior lens capsule during rinsing, causing surgical complications, resulting in poor surgical results and safety risks.

[0006] This invention is achieved through the following technical solution: A lens anterior and posterior capsule polisher includes a cleaning section and a conduit section connected in series; the cleaning section is a hollow cavity; a portion of the surface of the cleaning section is provided with an abrasive part, and a portion is provided with several through holes; in use, the free end of the conduit section is connected to an intraocular irrigation fluid.

[0007] Preferably, the cleaning part includes a hollow cavity formed by a top surface, a bottom surface, a first side surface, a second side surface, and a third side surface. The top surface and the bottom surface are both connected to the first side surface, the second side surface, and the third side surface, and the first side surface, the second side surface, and the third side surface are connected in sequence. The through holes are provided on the bottom surface, the first side surface, the second side surface, and the third side surface, and the frosted part is provided on the top surface.

[0008] Preferably, the connections between the top surface, bottom surface, first side surface, second side surface, and third side surface are all smoothly transitioned.

[0009] Preferably, the connection points of the top surface, bottom surface, first side surface, second side surface, and third side surface are all provided with rounded corners, the radius of which is 0.1~0.5 mm and the arc length is 0.157~0.785 mm.

[0010] Preferably, the radius of the through hole is 0.01~0.5 mm.

[0011] Preferably, from the free end of the cleaning section to the connection with the pipe section, the cross-sectional area of ​​the cleaning section gradually increases first and then gradually decreases.

[0012] Preferably, the pipeline includes a first pipe section and a second pipe section connected together; the connection between the first pipe section and the second pipe section is at an obtuse angle.

[0013] Preferably, the included angle at the connection between the first pipe segment and the second pipe segment is 120°~150°.

[0014] Preferably, the free end of the pipe section is further connected to a connecting part, and the free end of the connecting part is provided with an adapter, which is structurally compatible with national standard infusion sets and syringes.

[0015] Preferably, the interior of the connecting part is a hollow pipe, and the inner diameter of the connecting part gradually decreases from the free end of the main body to the connection end with the pipe part.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: This invention discloses a polisher for the anterior and posterior lens capsules. This polisher integrates a cleaning section and a conduit section into a single, unified device. The cleaning section is designed as a hollow cavity, with a portion of its surface having an abrasive layer and a portion having several through holes. The abrasive layer polishes the anterior lens capsule using friction, removing residual lens cortex and lens epithelial cells adhering to it, reducing the probability of postoperative lens capsular contraction, and increasing the stability of the intraocular lens and the persistence of postoperative vision. The through holes cooperate with the connected conduit section. When the free end of the conduit section is connected to intraocular irrigation fluid, the irrigation fluid can be sprayed out through the through holes at multiple angles and directions to rinse and polish the posterior lens capsule. Compared to existing water polishing techniques where the blunt needle can only spray a single jet of water in front of the needle, resulting in a limited rinsing angle, a small rinsing area, and a high risk of contact with the posterior capsule leading to rupture, this polisher achieves wider and more uniform rinsing. Furthermore, it utilizes the bottom water flow to push aside the posterior capsule, effectively improving surgical safety, postoperative visual acuity and visual quality, and reducing the incidence of posterior capsule opacification. This design allows for polishing of both anterior and posterior capsules with a single instrument, avoiding frequent instrument changes during surgery, simplifying the surgical procedure, and enhancing both surgical outcomes and safety.

[0017] Furthermore, the cleaning section includes a hollow cavity formed by a top surface, a bottom surface, a first side surface, a second side surface, and a third side surface. The top surface and the bottom surface are connected to the first side surface, the second side surface, and the third side surface, which are sequentially connected. The through holes are provided on the bottom surface, the first side surface, the second side surface, and the third side surface, and the abrasive part is provided on the top surface. By placing the through holes on the bottom surface, the first side surface, the second side surface, and the third side surface, multi-angle and multi-directional irrigation can be achieved, expanding the irrigation range and improving the irrigation effect on the posterior capsule of the lens. The abrasive part is provided on the top surface, which facilitates effective polishing of the anterior capsule of the lens using friction, enabling a single instrument to meet different polishing needs of the anterior and posterior capsules, reducing the need for instrument changes during surgery, simplifying the operation, and reducing surgical risks.

[0018] Furthermore, the connections between the top surface, bottom surface, first side surface, second side surface, and third side surface are all smoothly transitioned, which can prevent the sharp parts at the connections from scratching or damaging the corneal incision, lens capsule, or other ocular tissues during the surgical procedure, thereby improving the safety of the surgery and reducing the occurrence of complications.

[0019] Furthermore, the connection points of the top surface, bottom surface, first side surface, second side surface, and third side surface are all provided with rounded corners. The radius of the rounded corners is 0.1~0.5 mm, and the arc length is 0.157~0.785 mm. This allows for more precise control of the shape and size of the connection points. The appropriate rounded corner design can not only further reduce the risk of damage to the eye tissues, but also make the cleaning part operate more smoothly inside the eye, reduce friction with surrounding tissues, and improve the surgical experience and effect.

[0020] Furthermore, the radius of the through hole is 0.01~0.5 mm, which can precisely control the spray flow rate and velocity of the intraocular irrigation fluid. The appropriate radius can ensure that the irrigation fluid is sprayed out from the through hole at an appropriate pressure and flow rate, which can effectively flush away residual substances on the posterior capsule of the lens without causing damage to the posterior capsule due to excessive pressure, thereby improving the irrigation effect and surgical safety.

[0021] Furthermore, from the free end of the cleaning section to the connection with the channel section, the cross-sectional area of ​​the cleaning section gradually increases and then gradually decreases, making the free end of the cleaning section more slender, which facilitates operation in complex areas of the eye and reduces interference with surrounding tissues; then it gradually decreases, so that when it approaches the connection with the channel section, the cleaning section can form a certain converging effect, which is conducive to collecting and draining residual substances rinsed down, while making the overall structure more in line with the physiological structure of the eye, improving the convenience of operation and the surgical effect.

[0022] Furthermore, the conduit includes a first segment and a second segment connected together; the connection between the first segment and the second segment is at an obtuse angle. This design makes the transition of the conduit from outside the eye to inside the eye more natural and smooth, which conforms to the principles of ergonomics. During the surgical procedure, the doctor can more easily hold and manipulate the instruments, reducing the inconvenience caused by unreasonable angles of the conduit and improving the flexibility and precision of the surgery.

[0023] Furthermore, the included angle at the connection between the first and second pipe sections is 120°~150°. This further optimizes the shape and angle of the pipe section to better suit the needs of surgical procedures. A suitable angle ensures smooth flow of the cleaning fluid within the pipe, reducing fluid resistance, and also allows the surgeon to adjust the angle and position of instruments according to the surgical situation, improving surgical efficiency and effectiveness.

[0024] Furthermore, the free end of the tubing section is equipped with a connecting part, and the free end of the connecting part has an adapter. The adapter is structurally compatible with national standard infusion sets and syringes, facilitating connection with common medical equipment and making the supply of intraocular irrigation fluid more convenient and stable. Doctors can quickly change different irrigation fluid supply devices according to surgical needs, improving the flexibility and efficiency of surgery, while also facilitating the cleaning and disinfection of instruments, meeting medical standards and practical operational requirements.

[0025] Furthermore, the interior of the connecting part is a hollow pipe, and the inner diameter of the connecting part gradually decreases from the free end of the main body to the connection end with the pipe part. This design can increase the flow rate of the cleaning fluid in the connecting part, allowing the cleaning fluid to enter the cleaning section at a faster speed, thereby improving the flushing force and effect. At the same time, the gradually decreasing inner diameter can also play a certain role in stabilizing pressure, ensuring the stability and uniformity of the cleaning fluid spray, and further improving the quality of the surgery.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-2As shown, an anterior and posterior capsule polisher for the lens includes a cleaning section 1 and a conduit section 2 connected together. The cleaning section 1 is a hollow cavity, and the conduit section 2 is a hollow conduit. A portion of the surface of the cleaning section 1 is provided with an abrasive section 17, and a portion is provided with several through holes 16. In use, the free end of the conduit section 2 is connected to the intraocular irrigation fluid to supply the irrigation fluid. In this structure, the through holes 16 can be provided on all surfaces of the cleaning section 1 except for the abrasive section 17, or they can be provided only on a portion of the surface other than the abrasive section 17.

[0036] This invention mainly consists of a cleaning section 1 and a conduit section 2 connected together. The cleaning section 1 is a hollow cavity and is the core area for performing capsule polishing operations; the conduit section 2 is a hollow conduit responsible for delivering intraocular irrigation fluid. The two work together to complete the cleaning and polishing of the anterior and posterior capsules of the lens.

[0037] This invention features a frosted section 17 on one surface of the cleaning section 1 of the hollow cavity, with several through holes 16 on the remaining surfaces. By providing through holes 16 on multiple surfaces, the direction of the water jet can be controlled, allowing for rapid and comprehensive flushing of the lens capsule and removal of residual cortex and lens epithelial cells. Simultaneously, it enables polishing of both the anterior and posterior lens capsules using a single instrument, reducing the number of instruments required for intraocular insertion and removal during phacoemulsification cataract surgery, indirectly lowering the probability of postoperative endophthalmitis complications, and also reducing surgical instrument costs.

[0038] like Figures 3-4 As shown, the cleaning part 1 includes a hollow cavity composed of a top surface 11, a bottom surface 12, a first side surface 13, a second side surface 14, and a third side surface 15. The top surface 11 and the bottom surface 12 are both connected to the first side surface 13, the second side surface 14, and the third side surface 15, and the first side surface 13, the second side surface 14, and the third side surface 15 are connected and arranged in sequence. The top surface 11, bottom surface 12, first side surface 13, second side surface 14, and third side surface 15 are all smoothly connected. During the surgical procedure, the instruments need to frequently enter and exit the eye. The smooth transition at the connection can prevent the instruments from scratching or damaging the intraocular tissues during movement, which greatly improves the safety of the surgery.

[0039] The top surface 11, bottom surface 12, first side surface 13, second side surface 14 and third side surface 15 are all provided with rounded corners, the radius of the rounded corners is 0.1~0.5 mm and the arc length is 0.157~0.785 mm.

[0040] In a preferred embodiment, the through-hole 16 is disposed on the bottom surface 12, the first side surface 13, the second side surface 14, and the third side surface 15, and the abrasive portion 17 is disposed on the top surface 11. The abrasive portion 17, disposed on the top surface 11, primarily functions to polish the anterior capsule of the lens. During surgery, the abrasive portion 17, through direct contact with the inner surface of the anterior capsule and the generation of friction, effectively removes residual cortex and lens epithelial cells adhering to the anterior capsule. If these residual substances are not removed promptly, they may lead to a series of postoperative complications, such as posterior cataracts and capsule shrinkage. The polishing effect of the abrasive portion 17 significantly reduces the risk of these complications, improves the success rate of the surgery, and enhances the patient's postoperative visual quality.

[0041] This invention achieves comprehensive flushing of the lens capsule through the through-holes 16. By setting through-holes 16 on multiple surfaces, the direction of the water jet can be controlled, allowing the water flow to quickly and comprehensively cover all parts of the lens capsule. During surgery, after the intraocular irrigation fluid is delivered to the cleaning section 1 through the tubing section 2, it is ejected from these through-holes 16, forming a water flow with a certain pressure and direction. This water flow effectively cleans residual cortex and lens epithelial cells, ensuring the cleanliness of the inner surface of the lens capsule. The through-holes on the bottom surface 12, in particular, have a unique function. They not only flush away residual cortex on the posterior lens capsule but also generate a certain thrust through the ejected water jet, pushing the posterior capsule open and preventing direct contact between the posterior capsule and instruments. In traditional surgery, direct contact between instruments and the posterior capsule is a common cause of capsule rupture, which can lead to serious intraocular complications, affecting surgical outcomes and the patient's visual recovery. The design with 12 through holes on the bottom surface cleverly solves this problem and greatly improves the safety of the surgery.

[0042] Furthermore, in a preferred embodiment, the radius of the through hole 16 is 0.01~0.5 mm. This radius ensures that the water flow is ejected at an appropriate speed and pressure, which can effectively flush away residual substances on the surface of the capsule without causing excessive impact and damage to the intraocular tissues.

[0043] Furthermore, in a preferred embodiment, the cross-sectional area of ​​the cleaning section 1 gradually increases and then gradually decreases from its free end to its connection with the conduit section 2. During use, it can smoothly pass through the cataract surgery incision and enter the anterior chamber without damaging the incision or intraocular tissue. In cataract surgery, instruments need to enter the anterior chamber of the eye through a surgical incision. The gradually increasing cross-sectional area of ​​the cleaning section 1 allows for smoother entry and exit from the incision, preventing damage. Even when in contact with intraocular tissue, it will not cause damage. In contrast, if the cleaning section has a uniform cross-section or an unreasonable cross-sectional area variation, it will encounter greater resistance when entering the incision, leading to incision tearing or damage to intraocular tissue, increasing the risk of surgery and the probability of complications. Additionally, the gradually increasing and then decreasing cross-sectional area of ​​the cleaning section 1 prevents excessive friction or snagging with surrounding tissues during instrument removal, avoiding secondary damage to the cleaned area or surrounding normal tissues and ensuring the safety of the removal process. Meanwhile, the gradually decreasing cross-sectional area design allows the cleaning unit to be smoothly withdrawn from the body without the need for excessive force or complex angle adjustments, saving operation time and effort and improving the convenience of the entire cleaning and instrument removal process.

[0044] In addition, such as Figures 1-2 As shown, the conduit 2 includes a first tube segment 21 and a second tube segment 22 connected together; the connection between the first tube segment 21 and the second tube segment 22 is at an obtuse angle, allowing the cleaning unit 1 to enter the eye more easily. During operation, the doctor can more flexibly control the angle and direction of the instrument, smoothly delivering the cleaning unit 1 to the surgical site. Simultaneously, this obtuse angle design ensures the stability of the water flow direction at the outlet during use. If the angle at the connection is too small or the design is unreasonable, the water flow direction may deviate or become turbulent, affecting the flushing effect. The obtuse angle design ensures that the water flows out in the predetermined direction, guaranteeing effective flushing of the lens capsule.

[0045] In a preferred embodiment, the included angle at the connection between the first pipe segment 21 and the second pipe segment 22 is 120°~150°.

[0046] like Figures 1-2As shown, the free end of the tubing section 2 is also connected to a connecting section 3, and the free end of the connecting section 3 is equipped with an adapter 4. The connecting section 3 and the adapter 4 can be directly connected to a standard infusion set or syringe. Intraocular irrigation fluid is supplied via the standard infusion set or syringe. Simultaneously, the flow rate and pressure during surgery can be easily and efficiently controlled by adjusting the height of the connected infusion bottle or the injection speed of the syringe, meeting intraoperative needs. That is, the design of the connecting section 3 and the adapter 4 fully considers compatibility with existing medical equipment and ease of use. They can be directly connected to a standard infusion set or syringe, achieving a stable supply of intraocular irrigation fluid. This design makes the control of flow rate and pressure during surgery simple and efficient. The surgeon can precisely control the flow rate and pressure by adjusting the height of the connected infusion bottle or the injection speed of the syringe according to the actual needs of the surgery, while ensuring appropriate intraocular pressure. For example, when rapid flushing of a large amount of residual material from the inner surface of the intraocular capsule is needed or when intraocular pressure is low, the height of the infusion bottle can be increased or the syringe injection speed can be accelerated to increase the water flow rate and pressure. Conversely, when fine cleaning of the capsule is required or intraocular pressure is high, the height of the infusion bottle can be decreased or the syringe injection speed can be slowed down to make the water flow gentler. This flexible control of water flow rate and pressure can meet diverse intraoperative needs and provide strong support for the success of the surgery.

[0047] like Figure 5 As shown, the interior of the connecting part 3 is a hollow pipe, and the inner diameter of the connecting part 3 gradually decreases from the free end of the main body part 3 to the connection end with the pipe part 2. During the flow of intraocular irrigation fluid from the connecting part 3 to the pipe part 2, the water flow velocity gradually increases as the inner diameter of the pipe gradually decreases. According to the principles of fluid mechanics, under a constant flow rate, the smaller the cross-sectional area of ​​the pipe, the faster the water flow velocity. This design ensures that the irrigation fluid has sufficient velocity and pressure when it reaches the cleaning part 1, thereby better exerting its flushing effect. Simultaneously, the gradually decreasing inner diameter design also ensures a smoother water flow within the pipe, avoiding turbulence and further improving the stability of the water flow direction and the uniformity of the flushing effect.

[0048] The process of using the aforementioned lens capsular polisher is as follows: 1. First, connect the polisher to the standard infusion set or syringe via connector 3 and adapter 4 to establish the water supply system. The water flow rate is highly flexible and is determined by the height of the liquid bottle connected to the infusion set or the injection force of the syringe. Doctors can easily adjust the water flow rate according to the specific circumstances and needs of the surgery to ensure a stable water supply, good polishing effect, and maintenance of appropriate intraocular pressure during the operation.

[0049] 2. After establishing the water supply connection, the surgeon slowly inserts the polishing instrument into the eye through the main incision of the phacoemulsification cataract surgery. During this insertion, the unique shape of the cleaning unit 1 plays a crucial role; its gradually increasing cross-sectional area allows the instrument to pass smoothly through the surgical incision without causing any damage to the incision or intraocular tissues. Once inside the eye, water is injected—a critical step that maintains stable intraocular pressure during the procedure. Stable intraocular pressure is essential for the success of cataract surgery and the patient's safety: excessively high intraocular pressure can lead to serious complications such as increased pain, corneal edema, iris prolapse, lens capsular tears, retinal blood supply obstruction, and even optic nerve damage; while excessively low intraocular pressure can cause anterior chamber or even eyeball collapse, reducing surgical space, affecting surgical procedures, increasing the probability of complications such as posterior capsule rupture and corneal endothelial damage, and even causing excessive dilation of intraocular blood vessels, inducing iris or suprachoroidal hemorrhage and resulting in permanent vision loss. By maintaining an appropriate rate and flow of water into the eye, intraocular pressure can be effectively regulated, anterior chamber stability can be maintained, and a stable operating environment can be created for surgery.

[0050] 3. Once the polisher reaches the surgical site, the water flow direction is controlled through the through-hole 16. The water is sprayed out at a specific speed and pressure, providing a comprehensive, effective, and efficient flushing of the lens capsule. The through-hole on the bottom surface 12 not only flushes away residual cortex on the posterior lens capsule but also pushes the posterior capsule apart with the sprayed water jet, preventing direct contact between the posterior capsule and the instrument, effectively reducing the risk of posterior capsule rupture. When the abrasive section 17 begins to function, it polishes the anterior lens capsule. By abrading the anterior capsule, residual cortex and lens epithelial cells on the inner surface of the anterior capsule can be thoroughly removed, reducing the probability of "posterior cataract" and capsule shrinkage after phacoemulsification cataract surgery from the source.

[0051] Throughout the procedure, the water flow rate and pressure can be easily adjusted. Surgeons can adjust the flow rate and pressure at any time by adjusting the height of the IV bottle or the injection speed, depending on the stage of the surgery and the specific needs. For example, in the early stages of surgery or when intraocular pressure is low, a rapid initial flushing of the capsule may be necessary, in which case the water flow rate and pressure can be appropriately increased. Conversely, in the later stages of surgery or when intraocular pressure is high, for fine polishing and cleaning, the water flow rate and pressure can be reduced to ensure precision and safety. This flexible adjustment of water flow rate and pressure allows the polisher to adapt to various complex surgical situations, providing a strong guarantee for surgical success. This anterior and posterior capsule polisher, with its innovative structural design, rational component layout, and convenient use, has demonstrated superior performance and significant advantages in phacoemulsification cataract surgery. It not only effectively solves the problems of traditional surgical instruments, improving surgical safety and success rates, but also brings better postoperative visual quality to patients, possessing broad clinical application prospects and promotional value.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
