Description

Technical Field

[0001] The utility model relates to the technical field of clinical simulation, in particular to a simulated clinical experiment device based on metal artifacts. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] The widespread application of cone-beam computed tomography in the medical field has provided a powerful tool for clinical diagnosis and treatment. However, the presence of metal artifacts remains a major challenge for this technology. Metal artifacts are caused by high-density metal objects, such as implants, dental braces, and artificial joints, which seriously affect the image quality and, in turn, the accuracy and reliability of clinical diagnosis. Therefore, the processing effect of metal artifacts directly determines the actual judgment of clinical images and has become one of the important indicators for evaluating imaging quality.

[0004] Currently, the treatment of metal artifacts mainly relies on the improvement and optimization of image processing algorithms. However, existing metal artifact treatment methods still have limitations, mainly manifested in high algorithm complexity, long processing time, and poor treatment effects on certain types of metal artifacts. More importantly, there is currently a lack of effective simulation devices to optimize and verify these treatment methods, resulting in the effects of the treatment methods in practical applications often being less than expected. Summary of the invention

[0005] In order to solve the above technical problems, the utility model discloses a simulated clinical experiment device based on metal artifacts.

[0006] A simulated clinical experiment device based on metal artifacts includes a support base module and a simulated spine, wherein the base module is provided with a hollow space for placing the simulated spine, the simulated spine includes a simulated vertebral body module, a simulated intervertebral disc module and at least one simulated vertebral body module for implanting screws, and the device is used to simulate a human spine with implanted screws. The device can simulate the anatomical structure and tissue characteristics of the human spine, including the vertebral body, intervertebral disc and implanted screws, so that the clinical experiment is closer to the real situation.

[0007] Furthermore, the simulated vertebral body module and the simulated intervertebral disc module are alternately connected, and the simulated vertebral body module with implanted screws can replace the simulated vertebral body module and be connected to the simulated intervertebral disc module.

[0008] Furthermore, a simulated spinous process is provided on one side of the vertebral body module simulating the implanted screw, and implantation channels are provided on both sides of the simulated spinous process, and the implantation channels can connect the screws. The device is flexible in design and can be adjusted and customized according to different cases or experimental requirements, including the position and number of implanted screws of the simulated vertebral body.

[0009] Furthermore, the simulated vertebral body module, the simulated intervertebral disc module and the simulated screw implanted vertebral body module are respectively provided with simulated intervertebral neural foramina. The characteristics of the simulated vertebral body are retained as much as possible to ensure the authenticity of the built environment. The shape of the simulated vertebral body module is close to the geometric shape of the human lumbar spine.

[0010] Furthermore, the simulated vertebral body module and the simulated intervertebral disc module are respectively provided with simulated spinous processes.

[0011] Furthermore, the channel is symmetrically arranged relative to the simulated spinous process, and the angle formed by the central axis of the implantation channel is 40°-45°. Screw implantation channels with clinically reasonable angles and depths are designed on both sides of the simulated spinous process to prepare for the vertebral body for the simulated screw implantation.

[0012] Furthermore, the base module is made of a material with a density close to that of human tissue, such as transparent organic glass. The base module is made of transparent organic glass, which has a density close to that of human tissue, an elliptical cross section, close to the shape of the human lumbar spine, and a space is reserved above the geometric center for placing the vertebral module, the vertebral module simulating the implantation of pure titanium metal screws, and the intervertebral disc module.

[0013] Furthermore, the simulated vertebral body module and the simulated vertebral body module for implanting screws are made of materials with a density close to that of human bones, such as dark grey PVC material.

[0014] Furthermore, the simulated intervertebral disc module is made of transparent material, such as transparent organic glass.

[0015] Furthermore, the material of the screw is pure titanium metal. Pure titanium is a commonly used material in the field of clinical medicine, with a high degree of simulation. The simulated implant screw made of metal material can also ensure that it is not easy to break or shift during the simulation process.

[0016] As a further optimization of the technical solution, the present invention is applicable to different parts of the human spine, and the geometric dimensions, shapes and spaces for placing vertebral modules, vertebral modules simulating the implantation of pure titanium metal screws, and intervertebral disc modules can be optimized and combined according to the fatness or thinness of the human body.

[0017] The utility model has designed a clinical simulation experimental device with a metal implant that is highly similar to the clinical human body structure, made of special materials and highly practical, through structural innovation, effectively solving the practical problem that cone beam medical equipment lacks effective simulation of clinical effects in the early stage, thereby improving the practical problem of the accuracy of clinical images.

[0020] Figure 2 It is a cross-sectional schematic diagram of a vertebral module in the device that simulates the implantation of pure titanium metal screws. DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0022] Reference Figure 1 and Figure 2 The present invention provides a specific technical implementation scheme of a simulated clinical experimental device based on metal artifacts:

[0023] In the figure, the corresponding names of the numbers are as follows: 1-base module; 2-vertebral module; 3-hollow space; 4-vertebral module simulating implanted screws; 5-simulated spinous process; 6-implantation channel; 7-screw; 8-simulated intervertebral neural foramen; 9-simulated intervertebral disc module.

[0024] like Figure 1 As shown, a simulated clinical experimental device based on metal artifacts includes a supporting base module and a simulated spine, wherein the base module 1 is provided with a hollow space 3 for placing the simulated spine, the simulated spine includes a simulated vertebral module 2, a simulated intervertebral disc module 9 and at least one simulated vertebral module 4 for implanting screws, and the device is used to simulate a human spine with implanted screws.

[0025] The simulated vertebral body module 2 is connected alternately with the simulated intervertebral disc module 9 , and the simulated vertebral body module 4 with implanted screws can replace the simulated vertebral body module 2 and be connected with the simulated intervertebral disc module 9 .

[0026] like Figure 2 As shown, a simulated spinous process 5 is provided on one side of the vertebral body module 4 simulating the implant screw, and implantation channels 6 are respectively provided on both sides of the simulated spinous process 5, and the implantation channels 6 can be connected to the screw 7.

[0027] The simulated vertebral body module 2 , the simulated intervertebral disc module 9 and the simulated screw implanted vertebral body module 4 are respectively provided with simulated intervertebral neural foramina 8 .

[0028] The simulated vertebral body module 2 and the simulated intervertebral disc module 9 are respectively provided with simulated spinous processes 5 .

[0029] The cross section of the base module 1 is elliptical, and the hollow space 3 is arranged at an end of the cross section of the elliptical shape whose minor axis is far away from the center point.

[0030] The implantation channel 6 is symmetrically arranged relative to the simulated spinous process 5, and the angle formed by the central axis of the implantation channel 6 is 40°-45°. The depth is 40-60 mm.

[0031] The base module 1, the simulated vertebral module 2 and the simulated vertebral module 4 for implanting screws are respectively made of materials with a density close to that of the simulated object.

[0032] The material of the supporting base module 1 can be transparent organic glass (density is between 1.2g / cm3 and 1.5g / cm3), and the density is close to the density of human tissue.

[0033] The vertebral body module 2 may be made of dark grey PVC rods (density between 1.4 g / cm3 and 1.8 g / cm3), which has a density close to that of human bones.

[0034] The simulated intervertebral disc module 9 is made of transparent material. The screw 7 is made of pure titanium metal.

[0035] The simulated intervertebral neural foramen 7, which is approximately circular in shape, is indispensable in a simulated clinical experimental device based on metal artifacts. In actual clinical applications, the metal artifacts caused by the simulated vertebral body module 3 implanted with pure titanium metal screws will have a certain impact on the simulated intervertebral neural foramen 7 module. The impact effect is also a key simulation factor of a simulated clinical experimental device based on metal artifacts.

[0036] The steps for use are as follows:

[0037] Step 1: Preparation before simulation: assemble a suitable simulation device according to clinical needs, ensure the integrity of the device components, ensure that no image defects other than metal artifacts are generated during the angiography process, and implant screws into the vertebral module where the screws are simulated.

[0038] Step 2: Simulate imaging. Place the simulation device in an appropriate position for imaging, adjust environmental parameters, use image acquisition equipment to record and monitor the simulation process, and obtain real-time status of the simulation results.

[0039] Step 3: Analysis and improvement. After completing the simulated angiography process, analyze the experimental results and make necessary improvements, including device design, parameter adjustment, and material selection. Observe whether the metal artifact is complete and prepare for subsequent angiography image optimization.

[0040] In summary, for different preliminary simulated clinical experiments, the above-mentioned design concept can be used to design a clinical simulation experimental device that is highly close to the clinical human structure, made of special materials, and highly practical and includes metal implants. This effectively solves the practical problem that cone beam medical equipment lacks effective simulation of clinical effects in the early stage, thereby improving the accuracy of clinical images.
