Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a lens fixation marker, a manufacturing method thereof, and a device. Background Art

[0002] In ophthalmic surgery, the fixation and positioning of the lens are one of the key steps to ensure the success of the surgery. Especially in lens replacement surgery or other ophthalmic surgeries related to the lens, ensuring the correct placement of the lens and performing the surgery at the correct position of the lens are crucial for the success of the surgery, postoperative vision recovery, and eye health.

[0003] However, positioning the lens and performing the surgery requires the operator to estimate the needle insertion position based on experience, or to mark the left and right parallel lines by using an astigmatism marker, and then use other tools such as a scleral puncture trocar or a ruler to measure the specific position behind the corneal limbus. However, these methods are not only cumbersome, but also have the disadvantages of easy inaccuracy in operation and large measurement errors, and it is difficult to ensure the accuracy of the needle insertion position. There are still problems such as easy postoperative decentration, tilt of the intraocular lens, refractive error, and various complications.

[0004] With the development of modern medical technology, the humanized design and precise operation of surgical instruments have been increasingly emphasized. The optimized design of surgical instruments can not only improve the accuracy and safety of surgery, but also reduce the damage to the patient's tissues and enhance the patient's comfort. Therefore, there is an urgent need for a new type of surgical instrument for positioning the lens to solve the above problems. Summary of the Invention

[0047] Embodiment 1

[0048] Please refer to Figure 1 - Figure 2, in this embodiment, a lens fixation marker is proposed, which includes a handle 1 and a fixation base 3 connected to the handle 1. The handle 1 and the fixation base 3 are detachably connected in a dislocation manner. The fixation base 3 is provided with a notch on the side away from the handle 1. Both sides of the notch are provided with convex portions for marking the limbus of the lens, and both sides of the notch have arc-shaped smooth concave surfaces, so that the overall structure of the fixation base 3 is in a U-shaped semi-circular ring shape with the notch facing away from the handle 1;

[0049] Among them, the dislocation connection method between the handle 1 and the fixation base 3 enables the user to clearly observe the stable state of fixing the lens through the fixation base 3 and the marking situation of each convex portion on the fixation base 3 when holding the lens fixation marker proposed in this embodiment through the handle 1.

[0050] In this embodiment, the handle 1 and the fixation base 3 are dislocated and connected through a connecting rod 2. There is a first included angle between the connection direction of the connecting rod 2 and the fixation base 3 and the connection direction of the connecting rod 2 and the handle 1, so that when the user performs a fixation and marking operation through the lens fixation marker proposed in this embodiment, the hand posture can be more natural and ergonomic, thereby adapting to the operation needs of the human body, reducing the fatigue during the operation process and improving the comfort;

[0051] Preferably, the first included angle is greater than 90° and less than 180°. Exemplarily, the first included angle can be set to 120°, 135°, 150° or other angle degrees in the range of 90° to 180°.

[0052] In other embodiments, the connection end of the handle 1 and the fixation base 3 can also be set to have a specific degree of bending relative to the extension direction of the handle 1, or the edge of the handle 1 and the fixation base 3 can be connected, etc., so as to achieve the effect of dislocation connection.

[0053] Specifically, the convex portion on any side of the notch includes a first convex portion 31, a second convex portion 32, and a third convex portion 33 arranged in sequence. Among them, the first convex portion 31 is used to mark the limbus, the second convex portion 32 is used to mark the first position behind the limbus, and the third convex portion 33 is used to mark the second position behind the limbus;

[0054] In a specific embodiment, the first convex portion 31, the second convex portion 32, and the third convex portion 33 provided on the same side of the notch are located on the same straight line; there is a first distance between the first convex portion 31 and the second convex portion 32, a second distance between the second convex portion 32 and the third convex portion 33, and a third distance between the first convex portion 31 and the third convex portion 33, and the third distance is equal to the sum of the first distance and the second distance;

[0055] Preferably, the first spacing can be set to 1.0 mm - 4.0 mm, the second spacing can be set to 0.5 mm - 2.0 mm, and the third spacing can be set to 1.5 mm - 6.0 mm; exemplarily, the first spacing can be set to 2.0 mm, the second spacing can be set to 1.0 mm, and when the first spacing is 2.0 mm and the second spacing is 1.0 mm, the third spacing is correspondingly 3.0 mm.

[0056] Furthermore, the convex portions disposed on the two concave notches on the fixed base 3 are symmetrically distributed with respect to the handle 1. Thus, the lens fixing marker proposed in this embodiment can simultaneously mark the positions of the two limbus corneae and specific distances behind the two limbus corneae through the convex portions disposed on both sides of the notch.

[0057] Specifically, the cross-section of the connection end of the fixed base 3 and the handle 1 is circular, elliptical, a polygon with rotational symmetry, or a polygon-like shape with rotational symmetry. The handle 1 can be provided with an anti-fool connection mark corresponding to the fixed base 3 to facilitate the user to select the connection direction of the handle 1 and the fixed base 3 according to personal habits.

[0058] Preferably, an anti-slip structure 11 is provided on the side of the handle 1 away from the fixed base 3, so that the user can hold the lens fixing marker proposed in this embodiment through the anti-slip structure 11, thereby increasing the holding stability of the user during lens-related surgical operations and preventing operation errors caused by hand slipping; at the same time, the anti-slip structure 11 can have non-rotational symmetry, and the anti-slip structure 11 with non-rotational symmetry can be used as an anti-fool connection mark to facilitate the user's assembly and use;

[0059] In this embodiment, the anti-slip structure 11 can include anti-slip grooves opened on the side of the handle 1 away from the fixed base 3. In another embodiment, the anti-slip structure 11 can also include, but is not limited to, a rubber coating, a silica gel coating, and a concave-convex texture structure provided on the side of the handle 1 away from the fixed base 3.

[0060] Furthermore, the fixed base 3 is further provided with at least one observation hole 35 to facilitate the user to accurately position the lens fixing marker proposed in this embodiment through the observation hole 35, and then perform marking through the lens fixing marker. The extending direction of the observation hole 35 and the extending direction of the handle 1 form a second included angle;

[0061] In this embodiment, the fixed base 3 is detachably connected to the handle 1 through a boss 34. The observation hole 35 is opened on the boss 34, and the second included angle is greater than 45° and less than 135°. In a specific embodiment, the second included angle can be set to 90°.

[0062] Embodiment 2

[0063] Please refer to Figure 3, this embodiment proposes a manufacturing method for manufacturing the lens fixation marker proposed in Embodiment 1. The method includes:

[0064] S100: In response to a collection instruction, obtain the size information and curvature information of the cornea of the target object.

[0065] S200: Determine the base parameters based on the size information.

[0066] S300: Based on the base parameters, complete the manufacture of the fixation base by three-dimensional stereolithography, and assemble the fixation base obtained by three-dimensional stereolithography with a prepared handle to complete the manufacture of the lens fixation marker; or, based on the base parameters and preset handle parameters, complete the manufacture of the lens fixation marker by three-dimensional stereolithography.

[0067] In this embodiment, the base parameters may include, but are not limited to, the notch spacing value determined based on the size information, the concave curvature value determined based on the curvature information, and the position values and scale values of the first protrusion, the second protrusion, and the third protrusion determined based on the size information and the curvature information together;

[0068] Optionally, the notch spacing value can be set to match the size information, the concave curvature value can also be set to match the curvature information, and the position values and scale values of the first protrusion, the second protrusion, and the third protrusion can be determined based on the comparison difference between the size information, the curvature information and the preset standard size and the preset standard curvature;

[0069] Exemplarily, when the size information is smaller than the standard size and the curvature information is larger than the standard curvature, the spacing between the first protrusion, the second protrusion, and the third protrusion can be set to a smaller value, and the first protrusion, the second protrusion, and the third protrusion can be set to a smaller specification, and then the position values and scale values of the first protrusion, the second protrusion, and the third protrusion are determined;

[0070] When the size information is larger than the standard size and the curvature information is smaller than the standard curvature, the spacing between the first protrusion, the second protrusion, and the third protrusion can be set to a larger value, and the first protrusion, the second protrusion, and the third protrusion can be set to a larger specification, and then the position values and scale values of the first protrusion, the second protrusion, and the third protrusion are determined.

[0071] It should be noted that the lens fixation marker manufactured by the method proposed in this embodiment has the advantages of durability and wear resistance, and can be reused multiple times by medical disinfection with ethylene oxide;

[0072] In a specific embodiment, the notch spacing value may include the notch transverse diameter value and the notch longitudinal diameter value. The method proposed in this embodiment can fabricate a number of corresponding lens fixing markers based on common base parameters to meet the requirements of most target objects.

[0073] Exemplarily, when the common notch transverse diameter values are 10 mm, 11 mm, or 12 mm, and the common notch longitudinal diameter values are 5.5 mm, 5.6 mm, the method proposed in this embodiment can combine the notch transverse diameter values of 10 mm, 11 mm, and 12 mm with the notch longitudinal diameter values of 5.5 mm and 5.6 mm through permutation and combination to fabricate a number of lens fixing markers corresponding to different combinations of notch transverse diameter values and notch longitudinal diameter values.

[0074] In view of the differences in the eye structures of different individuals, the method proposed in this embodiment fabricates the fixing base based on the size and curvature information of the cornea, which can ensure a more fitting, comfortable, and efficient usage experience. Through the fabrication method proposed in this embodiment, the design of the fixing base can be precisely controlled, effectively avoiding discomfort or poor effects caused by design deviations, and improving the accuracy and stability of the entire marker.

[0075] Compared with traditional manufacturing processes, 3D printing technology can complete the fabrication of customized products in a shorter time, while reducing manual intervention and error rates. The fabrication method proposed in this embodiment uses 3D printing technology to fabricate the fixing base, which can achieve more complex and delicate structural designs, and the manufacturing process is flexible, facilitating adaptation to different shapes and size requirements. Moreover, the handle part can adopt a fixed design. Only by fabricating the fixing base through 3D printing and connecting the fabricated fixing base to a pre-prepared handle can the assembly of the lens fixing marker be completed, or the lens fixing marker can be directly fabricated through 3D printing in combination with preset handle data, thus achieving the advantages of personalized customization, high-precision design, and rapid production.

[0076] Furthermore, the base parameters may further include identification data. Step S200 can complete the fabrication of the fixing base or the lens fixing marker through 3D printing based on the base parameters including the identification data. Please refer to Figure 4 On this basis, the method further includes:

[0077] S400: After completing the fabrication of the fixing base, generate fabrication data based on the current size information, curvature information, and base parameters and record them.

[0078] S500: After the size information and curvature information are collected through step S100, if the deviation values of the current size information and curvature information from the size information and curvature information in any production data do not exceed a preset difference value, the identification data in the production data will be displayed to the user, so that the user can search for the corresponding lens fixing marker based on the identification data.

[0079] It should be noted that the identification data may include, but is not limited to, patterns, digital numbers, corresponding size information and curvature information. The identification data can facilitate the user to distinguish different specifications of the fixing bases. When making the fixing bases, if the current requirements are highly similar to the recorded data, that is, it can be confirmed that there has been a fixing base that can directly reuse its data in the past, then the method proposed in this embodiment can provide the corresponding identification data, so that the user can directly use the identification data to search for the existing lens fixing marker, thereby reducing the production steps and achieving the effect of saving production costs.

[0080] At the same time, the identification data provides a traceability function for each production data of the fixing base. Through the identification data and the production data containing the identification data, the method proposed in this embodiment can be traced, verified and adjusted in subsequent use, so as to optimize the method of making the fixing base by three-dimensional printing accordingly, ensure that each base meets the expected design requirements, and can also optimize the preset difference value data, so as to achieve that as long as the deviation value of the current base parameters from the base parameters in any production data does not exceed the preset difference value, the fixing base corresponding to the identification data can directly reuse the existing data without having to determine the production data of the fixing base again, which helps to improve the accuracy, efficiency and quality control of the overall production process.

[0081] On this basis, the method proposed in this embodiment may further include:

[0082] S600: In response to the user's re-production instruction, based on the base parameters in the production data, complete the production of the fixing base by three-dimensional printing, and assemble the fixing base obtained by three-dimensional printing with the prepared handle to complete the production of the lens fixing marker;

[0083] Or, complete the production of the lens fixing marker by three-dimensional printing based on the base parameters and the preset handle parameters.

[0084] Through step S600, the method proposed in this embodiment can provide the corresponding identification data for the user, so that the user can directly use the base parameters containing the identification data to make a specific fixing base, thereby reducing the steps of generating production data and reducing the steps of generating production data without reusing the existing lens fixing marker.

[0085] Preferably, the method proposed in this embodiment can also respond to a user's input instruction to add production data based on the input instruction and record it; the input instruction may include the notch spacing value, the concave curvature value, the position values and scale values of the first protrusion, the second protrusion, and the third protrusion;

[0086] Correspondingly, the method proposed in this embodiment can also respond to a user's change instruction to modify or delete the recorded production data based on the change instruction.

[0087] By enabling the method proposed in this embodiment to respond to the user's input instruction to add production data or respond to the user's change instruction to modify or delete production data, it is possible to flexibly meet different requirements. The user can quickly enter new data into the system according to the specific situation, enhancing the flexibility and efficiency of data input;

[0088] Exemplarily, if there are multiple systems using the method proposed in this embodiment, the user can generate an input instruction or a change instruction on another system based on the data that has been verified on one system, thereby ensuring the accuracy and consistency of data between each system and effectively avoiding the negative impact brought by incorrect data.

[0089] Embodiment 3

[0090] This embodiment proposes a three-dimensional printing device for implementing the steps of the production method proposed in Embodiment 2, namely:

[0091] S100: In response to a collection instruction, obtain the size information and curvature information of the cornea of the target object.

[0092] S200: Determine the base parameters based on the size information, and complete the production of the fixed base by three-dimensional printing based on the base parameters.

[0093] S300: Assemble the fixed base obtained by three-dimensional printing with a prepared handle to complete the production of the lens fixing marker.

[0094] S400: After completing the production of the fixed base, generate production data based on the current size information, curvature information, base parameters, and identification data and record it.

[0095] S500: When the size information and curvature information are obtained through step S100, if the deviation value between the current size information and curvature information and the size information and curvature information in any production data does not exceed a preset difference value, the identification data in the production data will be displayed to the user and the user will be prompted to confirm.

[0096] S600: In response to the confirmation instruction, based on the pedestal parameters and identification data in the production data, the production of the fixed pedestal is completed by three-dimensional printing.

[0097] Optionally, the three-dimensional printing device proposed in this embodiment may include, but is not limited to, a fused deposition modeling (FDM) 3D printer, a stereolithography (SLA) 3D printer, a digital light processing (DLP) 3D printer, and a PolyJet 3D printer.

[0098] In summary, the present invention proposes a lens fixing marker, a manufacturing method thereof, and a device.
