Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a lens fixation marker. Background Technology

[0002] Lens dislocation is a common ophthalmic disease caused by congenital malformation or acquired trauma. This condition not only causes decreased vision but also leads to complications such as increased intraocular pressure and vitreoretinal disease. In the surgical treatment of lens or artificial lens dislocation and displacement, accurate positioning and fixation of the lens is one of the key steps to ensure success.

[0003] Currently, locating the lens and performing surgery requires the operator to estimate the needle insertion point based on experience, or to mark the left and right parallel lines using an astigmatism marker, and then use other tools such as a scleral puncture knife or a ruler to measure the specific position behind the limbus. However, these methods are not only cumbersome, but also have the disadvantages of being easy to be inaccurate and having large measurement errors.

[0004] To improve surgical accuracy and reduce potential risks, many marking methods and devices have been proposed to assist in the procedure. However, existing related solutions, which mainly focus on improving surgical techniques for intraocular lens fixation, still struggle to guarantee the accuracy of needle insertion. This can easily lead to postoperative intraocular lens displacement, tilting, refractive errors, and various complications. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model proposes a lens fixation marker, including a handle, a fixing base, and a connecting rod for connecting the handle and the fixing base. The handle is detachably connected to a first end of the connecting rod, and the fixing base is detachably connected to a second end of the connecting rod.

[0006] The fixing base has a concave surface on the side away from the handle, and the concave surface is provided with a number of marked protrusions.

[0007] Specifically, the connecting rod has a first angle between its extension direction toward the first end and its extension direction toward the second end; the first angle is greater than 90° and less than 180°.

[0008] Furthermore, the extension direction of the first end of the connecting rod is the same as the extension direction of the handle, and the cross-section of the first end of the connecting rod is circular, elliptical, a polygon with rotational symmetry, or a polygon-like shape with rotational symmetry. The handle is provided with a foolproof connection mark corresponding to the connecting rod.

[0009] Preferably, the fixing base has a first base member and a second base member extending from the side away from the handle to both ends;

[0010] The marking protrusion includes a first protrusion, a second protrusion, and a third protrusion disposed on the first base; and / or includes a first protrusion, a second protrusion, and a third protrusion disposed on the second base.

[0011] Preferably, the concave surface comprises an arcuate surface formed by the first base member and the second base member on the side away from the handle.

[0012] Specifically, there is a first distance between the first protrusion and the second protrusion, a second distance between the second protrusion and the third protrusion, and a third distance between the first protrusion and the third protrusion.

[0013] The third spacing is equal to the sum of the first spacing and the second spacing.

[0014] Optionally, the first spacing ranges from 0.5mm to 4.0mm, the second spacing ranges from 0.5mm to 4.0mm, and the third spacing ranges from 1.5mm to 6.0mm.

[0015] Preferably, the marking protrusions include a first protrusion, a second protrusion, and a third protrusion disposed on the first base and a first protrusion, a second protrusion, and a third protrusion disposed on the second base; the protrusions disposed on the first base and the protrusions disposed on the second base are symmetrically distributed on the concave surface with respect to the handle;

[0016] The fixed base is also provided with an adjusting member that movably connects the first base and the second base, so that the distance between the first base and the second base can be increased or decreased within a preset distance range based on the movement of the adjusting member.

[0017] Preferably, the side of the handle away from the fixed base is provided with an anti-slip structure.

[0018] Furthermore, the fixed base is also provided with an observation hole, and the extension direction of the observation hole has a second included angle with the extension direction of the connecting rod toward the second end;

[0019] The second included angle is greater than 45° and less than 135°.

[0020] This utility model has at least the following beneficial effects:

[0021] The lens fixation marker proposed in this utility model can better fit the target area through the concave surface set on the fixation base to avoid slippage, and then provide precise positioning through the marking protrusion. The handle, connecting rod and fixation base are detachably connected. Users can adjust the structure of the marker according to different operational needs and clinical conditions, which can ensure that different operational needs can be met, and provide flexibility for easy manufacturing, transportation, storage, cleaning or adjustment, improve the accuracy and convenience of operation, and provide medical staff with a more reliable tool.

[0022] Furthermore, the lens fixation marker proposed in this utility model improves safety and comfort during use by setting the angle of the connecting rod, making the overall structure more stable in different working postures, thus facilitating user operation and avoiding the difficulty of adjustment caused by an excessively small angle; the first end of the connecting rod is aligned with the extension direction of the handle, which helps to improve the efficiency of force transmission, allowing the user's operation to be more natural and reducing unnecessary torsional forces; the design of selecting a circular, elliptical, or rotationally symmetric polygonal cross-section and setting a foolproof mark allows for easy connection from various different directions, catering to the personal habits of different operators and the needs of different operating environments;

[0023] Based on this, the present invention effectively enhances the structural strength of the fixation base by adding multiple base components, providing higher stability. The spacing design of multiple marking protrusions allows for precise positioning of the lens, while the arc-shaped curved surface design may enhance the uniformity of force distribution on the base, making the fixation base more robust during use and less prone to local damage or deformation. Users can also adjust the spacing between the two base components using the adjustment mechanism according to different surgical conditions. The anti-slip structure effectively improves the grip strength of the handle, preventing accidents caused by slipping. The observation hole allows users to view the working status or positional changes of the markers during operation, thereby increasing operational accuracy.

[0024] Therefore, this utility model proposes a lens fixation marker. The marker proposed by this utility model helps users mark specific positions of the lens during actual surgical operations. The overall structure of the marker is simple, the operation is not complicated, and the method of use is intuitive and easy to learn, which improves the operation efficiency, effectively reduces the risk of misalignment during surgery, improves the stability and safety of operation, and thus improves the surgical effect and patient satisfaction. The multiple connection designs between the connecting components allow users to flexibly select and adjust the device as needed, while also facilitating the cleaning, storage and replacement of the components.

[0050] Preferably, the first spacing can be set to 0.5mm-4.0mm, the second spacing can be set to 0.5mm-4.0mm, and the third spacing can be set to 1.5mm-6.0mm; for example, the first spacing can be set to 2.0mm, the second spacing can be set to 1.0mm, and when the first spacing is 2.0mm and the second spacing is 1.0mm, the third spacing is 3.0mm accordingly.

[0051] Furthermore, the marking protrusions include a first protrusion 301, a second protrusion 302, and a third protrusion 303 disposed on the first base 31 and a first protrusion 301, a second protrusion 302, and a third protrusion 303 disposed on the second base 32; the protrusions disposed on the first base 31 and the protrusions disposed on the second base 32 are symmetrically distributed on the concave surface with the handle 1 as a reference.
