Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a measuring tool ruler for teaching endoscopic correction surgery. Background Art

[0002] In ophthalmology, a procedure for correcting high myopia is called ICL surgery. The "Implantable Collamer Lens" (ICL) is a safe, high-end myopia correction option. Unlike laser and other procedures that abbreviate corneal tissue, ICL does not ablate the cornea. Instead, the lens is implanted in the eye through a minimally invasive procedure, leaving no damage to the cornea. This procedure offers clearer vision and represents a new trend in myopia correction. ICLs are implanted in the posterior chamber of the eye, between the iris and the lens. To achieve clear vision, precise placement of the ICL during surgery is crucial. During ICL surgery, the ICL's position is crucial, both in relation to the surgical incision and the degree of ICL rotation required. Currently known incision designs include temporal, oblique, and superior. The degree of ICL rotation is calculated by a lens calculator, and the appropriate rotation angle is used to correct refractive astigmatism.

[0003] In the current teaching model, there is no clear teaching tool for the rotation angle of the intraocular lens, that is, the purpose of correctly placing the intraocular lens is achieved by rotating the central intraocular lens position angle. The existing teaching tools mainly rely on observing the required rotation degree of the intraocular lens through surgical videos. During teaching, students cannot use the tools to perform repeated operations on their own and cannot deeply understand the personalized surgical design plan. Therefore, a measuring tool ruler for teaching endoscopic corrective surgery is proposed as a teaching tool to assist teaching. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a measuring tool ruler for teaching endoscopic corrective surgery, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by the utility model is: a measuring tool ruler for teaching endoscopic corrective eye surgery (ICL), comprising a disc main ruler, an outer scale and an inner scale provided on the upper end of the disc main ruler, a marking ruler provided on the upper end of the disc main ruler, a gasket provided on the upper end of the marking ruler, a fixer provided on the upper end of the gasket, and a fixing nut provided on the lower end of the disc main ruler;

[0006] The marking ruler includes a pointer ruler, an observation window and a reference line. The upper end of the pointer ruler is provided with an observation window, and the upper end of the pointer ruler is provided with a reference line.

[0007] Preferably, there are two external scales, which are arranged at the upper and lower half of the outer ring of the main scale of the disc, and the angle range of the external scale is 0°~180°.

[0008] Through the above technical solution, external and internal scales are set, and the scale indications are comprehensive, so the actual rotation angle of the crystal model can be measured accurately.

[0009] Preferably, the inner scale is arranged on the entire circumference of the inner ring of the main scale of the disc, the angle range of the inner scale is 0°~360°, and the observation window corresponds to the inner scale.

[0010] Through the above technical solution, an observation window is provided. When the pointer scale is rotated, the observation window corresponds to the inner scale. When the pointer scale rotates more than half a circle, the actual rotation angle of the pointer scale can be observed.

[0011] Preferably, fixing holes are provided on the upper ends of the main disc ruler, the marking ruler and the crystal model, and the fixer is threadedly connected to the fixing nut.

[0012] Through the above technical solution, when the disc main ruler, marking ruler and crystal model are assembled, the gasket is placed above the crystal model, the fixture is passed through the fixing holes of the disc main ruler, marking ruler and crystal model and then assembled with the fixing nut thread, and the disc main ruler, marking ruler and crystal model rotate with the center of the fixture as the axis, with good mobility.

[0013] Preferably, the reference line coincides with the center axis of the pointer ruler.

[0014] Through the above technical solution, a reference line is set, and when the central axis of the crystal model needs to coincide with the central axis of the marking ruler, the reference line provides an auxiliary alignment function.

[0015] Preferably, one end of the pointer ruler is a pointer-shaped structure, and the other end of the pointer ruler is an arc structure.

[0016] Through the above technical solution, one end of the pointer ruler is in the form of a pointer, which can be accurately aligned with the external scale to display the actual rotation angle of the pointer ruler.

[0017] Preferably, the crystal model is made of transparent acrylic, and a focus is provided on the surface of the crystal model.

[0018] Through the above technical solution, the crystal model is made of transparent acrylic, which is easy to observe. A focus is set on the surface of the crystal model. When the central axis of the crystal model coincides with the central axis of the marking ruler, the focus is aligned with the reference line, and the alignment effect is good.

[0019] Compared with the existing technology, the present invention provides a measuring tool ruler for teaching endoscopic corrective surgery, which has the following beneficial effects:

[0020] 1. This measuring tool for teaching endoscopic corrective surgery is equipped with a main disc ruler, a marking ruler, and a lens model. The central axis of the lens model is aligned with the central axis of the marking ruler. By rotating the marking ruler and observing the angle between the main disc ruler and the marking ruler, the actual required rotation angle of the lens model can be measured. This solves the problem of being unable to accurately measure the angle by rotating the physical lens model in existing clinical teaching. It also solves the problem of abstract teaching in actual teaching and the inability to obtain the exact position through measurement, thereby improving teaching quality.

[0021] 2. The measuring tool ruler for teaching endoscopic corrective surgery is equipped with a reference line. When the central axis of the lens model needs to coincide with the central axis of the marking ruler, the reference line provides an auxiliary alignment function, and the focus is aligned with the reference line, with a good alignment effect. External and internal scales are set, and the scale indications are comprehensive, which can measure the actual rotation angle of the lens model and measure accurately. When the pointer ruler is rotated, one end of the pointer ruler is in a pointer-shaped structure, which can be accurately aligned with the external scale. The observation window corresponds to the internal scale, and the actual rotation angle of the pointer ruler can be observed. The structure of the device is simple and easy to manufacture.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Figure 1-5 As shown, the utility model provides a measuring tool ruler for teaching endoscopic corrective surgery, comprising a main disc ruler 1, an outer scale 2 and an inner scale 3 are provided on the upper end of the main disc ruler 1, a marking ruler 4 is provided on the upper end of the main disc ruler 1, a gasket 6 is provided on the upper end of the marking ruler 4, a fixture 7 is provided on the upper end of the gasket 6, and a fixing nut 8 is provided on the lower end of the main disc ruler 1;

[0030] The marking ruler 4 includes a pointer ruler 401 , an observation window 402 and a reference line 403 . The observation window 402 is provided at the upper end of the pointer ruler 401 , and the reference line 403 is provided at the upper end of the pointer ruler 401 .

[0031] Specifically, two external scales 2 are provided, one on each of the upper and lower halves of the outer circumference of the main disc scale 1. The angle range of the external scales 2 is 0° to 180°. Advantageously, the external scales 2 and the internal scale 3 provide comprehensive scale indications, enabling accurate measurement of the actual rotation angle of the crystal model 5.

[0032] Specifically, inner scale 3 is provided along the entire circumference of the inner ring of the main disc scale 1, with an angular range of 0° to 360°. Observation window 402 corresponds to inner scale 3. Advantageously, provision of observation window 402 allows for alignment with inner scale 3 when pointer scale 401 is rotated. When pointer scale 401 rotates more than half a turn, the actual rotation angle of pointer scale 401 can be observed.

[0033] Specifically, the main disc ruler 1, marking ruler 4, and crystal model 5 all have fixing holes at their upper ends, and a retainer 7 is threadedly connected to a fixing nut 8. This arrangement advantageously allows for easy assembly of the main disc ruler 1, marking ruler 4, and crystal model 5 by placing a gasket above the crystal model 5, inserting the retainer 7 through the fixing holes in the main disc ruler 1, marking ruler 4, and crystal model 5, and then threading it into the fixing nut 8. The main disc ruler 1, marking ruler 4, and crystal model 5 can then rotate about the center of the retainer 7, providing excellent mobility.

[0034] Example 2: Figure 2-5 As shown, as an improvement to the previous embodiment.

[0035] Specifically, the reference line 403 coincides with the central axis of the pointer ruler 401. Advantageously, the reference line 403 can assist in alignment when the central axis of the crystal model 5 needs to coincide with the central axis of the marking ruler 4.

[0036] Specifically, one end of the pointer scale 401 is in a pointer-shaped structure, and the other end of the pointer scale 401 is in an arc structure. The advantage is that the pointer scale 401 has a pointer-shaped structure at one end, which can accurately align with the outer scale 2 to display the actual rotation angle of the pointer scale 401.

[0037] Specifically, the crystal model 5 is made of transparent acrylic, and a focal point is provided on the surface of the crystal model 5. Advantageously, the crystal model 5 is made of transparent acrylic, making it easier to observe, and the focal point provided on the surface of the crystal model 5 allows for good alignment when the central axis of the crystal model 5 coincides with the central axis of the marking ruler 4.

[0038] Working principle: During assembly, place the gasket above the crystal model 5, pass the holder 7 through the fixing holes of the disc main scale 1, the marking ruler 4 and the crystal model 5, and then threadably assemble with the fixing nut 8. The disc main scale 1, the marking ruler 4 and the crystal model 5 rotate with the center of the holder 7 as the axis, and have good mobility. During use, the central axis of the crystal model 5 is aligned with the central axis of the marking ruler 4. When the focus is aligned with the reference line 403, it is in the overlapping state. By rotating the marking ruler 4, one end of the pointer ruler 401 is in a pointer-shaped structure, which can be accurately aligned with the outer scale 2. The observation window 402 corresponds to the inner scale 3. The actual rotation angle of the pointer ruler 401 can be observed to measure the actual required rotation angle of the crystal model 5 until the correct required scale is reached.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
