[0040] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully communicated to those skilled in the art.

[0041] Embodiment 1:

[0042] An embodiment of the present invention provides a method for constructing a model for clinical operations, as Figure 1 shown, including:

[0043] S101, scanning the target operation site to determine the medical image data of the target operation site, where the target operation site includes: a blood vessel region, a bone region, and a nerve region;

[0044] S102, based on the medical image data, drawing a three-dimensional image of the target operation site and the surrounding tissues;

[0045] S103, inputting the data corresponding to the three-dimensional image into a 3D printer, and using a biomimetic material to generate a biomimetic target operation site model through the 3D printer;

[0046] S104, setting corresponding monitoring devices at preset positions on the biomimetic target operation site model, and completing the corresponding clinical operations under ultrasonic guidance.

[0047] First, the clinical operations here specifically include operations on the blood vessel region, operations on the bone region, and operations on the nerve region. For each operation type, there can also be multiple biomimetic models. For example, for PICC insertion operation skills and pulmonary artery catheter insertion operation skills, since the body parts targeted are different, the biomimetic models are also different.

[0048] In S101, the target operation site is scanned to determine the medical image data of the target operation site. Here, for different clinical operations, the scanned sites are different.

[0049] Operation sites for the blood vessel region: Corresponding clinical operations include: PICC insertion operation skills, pulmonary artery catheter insertion operation skills, arterial puncture operation skills, and central venous puncture operation skills. Of course, there are other clinical operations besides this, which are not limited herein.

[0050] For PICC insertion operation skills, specifically, the peripheral vein and the central vein region are scanned.

[0051] For pulmonary artery catheter insertion operation skills, specifically, the elbow vein, femoral vein, internal jugular vein, or subclavian vein region is scanned.

[0052] For arterial puncture operation skills, specifically scan the radial artery area, dorsalis pedis artery area, femoral artery area, etc.

[0053] For deep vein puncture operation skills, specifically scan the jugular vein area, subclavian vein area, etc.

[0054] For the scan of the vascular area, select CT scan to obtain medical image data on the diameter, curvature, and bifurcation position of the blood vessels.

[0055] For the operation sites in the bone area: The corresponding clinical operations include: intraspinal puncture operation skills and sacral canal puncture operation skills. Of course, in addition to this, there are other clinical operations for bones, which are not limited here.

[0056] For intraspinal puncture operation skills, specifically scan the human spine and intervertebral disc area.

[0057] For sacral canal puncture operation skills, specifically scan the human sacral canal area.

[0058] For the scan of the bone area, select MRI for scanning to obtain medical image data on the size, curvature, and bifurcation position of the bones.

[0059] For the operation sites in the nerve area, the corresponding clinical operations include: upper limb nerve area, lower limb nerve area, abdominal wall nerve area, cranial nerve area, and peripheral nerve area. Of course, in addition to this, there are other clinical operations for nerves, which are not limited here.

[0060] For the upper limb nerve area, specifically scan the nerve areas of each part. Specifically, select MRI for scanning to obtain medical image data on the position, length, positional relationship between each other, and positional relationship with adjacent bones of each nerve area.

[0061] For the above-mentioned operation sites, they can be either of children or adults, which is not limited here, and adults or children can be selected according to actual operation training.

[0062] Next, execute S102. Based on the medical image data, draw a three-dimensional image of the target operation site and the surrounding tissues.

[0063] Specifically, when the target operation site is the vascular area, based on the medical image data, through segmentation, reconstruction, and optimization, construct the morphology of the blood vessels, as well as the muscle tissue, fat layer, and skin around the blood vessels, and draw a three-dimensional image of the vascular area and the surrounding tissues.

[0064] Based on the medical image data, three-dimensional point cloud data is constructed. Then, background noise is removed from these three-dimensional point cloud data, and holes are repaired. After the repair of the three-dimensional point cloud data, the morphology of blood vessels and the surrounding muscle tissue, fat layer, and skin are constructed by means of segmentation, reconstruction, and optimization of the model surface. Thus, a three-dimensional image of the blood vessel area and the surrounding tissues is drawn.

[0065] When the target operation site is a bone area, based on the medical image data, the morphology of the bone and the surrounding ligaments, muscle tissue, fat layer, and skin are constructed through segmentation, reconstruction, and optimization, and a three-dimensional image of the bone area and the surrounding tissues is drawn.

[0066] For the bone area, based on the size, curvature, and characteristics of the horizontal cross-section of the scanned bone, three-dimensional point cloud data of the sacral canal area can be constructed, thereby constructing a three-dimensional model of the sacral canal area. Similarly, for the human spinal column and intervertebral disc areas, three-dimensional models are also constructed in this way. Finally, three-dimensional images of the corresponding bone areas and the surrounding tissues are drawn.

[0067] When the target operation site is a nerve area, based on the medical image data, the distribution state of the nerves and the surrounding bones, muscle tissue, fat layer, blood vessels, and skin are constructed through segmentation, reconstruction, and optimization, and a three-dimensional image of the nerve area and the surrounding tissues is drawn.

[0068] For nerves in different regions, three-dimensional images are constructed separately. For example, in the upper limb nerve area, for the shoulder nerves, only the cervical plexus and brachial plexus can be constructed to obtain a three-dimensional image of the shoulder nerves. In the specific drawing process, based on the medical image data, three-dimensional point cloud data is first constructed, and then, based on this three-dimensional point cloud data, the nerves in the shoulder area and the surrounding bones, muscle tissue, fat layer, blood vessels, and skin are constructed, thereby obtaining a three-dimensional image.

[0069] Next, S103 is executed, and the data corresponding to the three-dimensional image is input into a 3D printer, and a bionic target operation site model is generated by the 3D printer using bionic materials.

[0070] In a specific implementation manner, the data corresponding to the three-dimensional image is input into a 3D printer, and a bionic target operation site model is printed layer by layer by the 3D printer using bionic materials. An ultrasonic elastic bionic tissue body membrane is set for each tissue of each target operation site model to achieve feedback under ultrasonic guidance.

[0071] First, when printing and outputting a target operation site model based on the data corresponding to the three-dimensional image through a 3D printer, layer-by-layer printing is performed. For example, the bone is printed first, and then the muscle tissue and the wrapped fat layer are printed. Among them, blood vessels and nerves are interspersed in the muscle, and the outermost layer is the skin. Among them, ligaments are used at the bone joints.

[0072] Since in order to be able to visually see the process of clinical operations, ultrasonic elastomeric biomimetic tissue membranes can be set on each tissue of each target operation site model. These membranes specifically use PMMA or aluminum as ray-blocking simulation materials, and also use gelatin, silicone, and polyurethane materials, and polyvinyl chloride with different softener ratios to simulate soft tissues.

[0073] The ultrasonic elastomeric biomimetic tissue membrane can achieve feedback under ultrasonic guidance, obtain ultrasonic images, and be used to guide the operation process.

[0074] Finally, execute S104, set corresponding monitoring devices at the preset positions of the biomimetic target operation site model, and complete the corresponding clinical operations under ultrasonic guidance.

[0075] For different biomimetic target operation site models, different monitoring devices are used.

[0076] In the clinical operation: for any one of the PICC insertion operation skills, floating catheter insertion operation skills, arterial puncture operation skills, and deep vein puncture operation skills in the blood vessel area, a tin foil layer is set inside the blood vessel of the corresponding biomimetic target operation site model. This tin foil layer is used to detect whether the catheter abuts against the inner wall of the blood vessel. If the catheter abuts against the tin foil layer, the alarm is activated. A conductive probe is set at the short part of the catheter, and the other end of the tin foil is connected to the alarm device, and this conductive probe is connected to the alarm device. By connecting the conductive probe, the tin foil, and the alarm device in series, when the conductive probe pierces or presses the tin foil set on the inner wall of the blood vessel, the indicator light of the alarm device lights up, thereby indicating that the operation is incorrect; while when the operation is normal, the indicator light of the alarm device will not continuously light up.

[0077] In the clinical operation: for any one of the sacral canal puncture operation skills and intraspinal canal puncture operation skills in the bone area, a first indicator light is connected and set at the puncture point of the corresponding biomimetic target operation site model, and when the first puncture needle reaches the puncture point, the first indicator light is controlled to light up to indicate that the corresponding puncture operation is successful.

[0078] Specifically, the puncture point, the first indicator light, and the first puncture needle are connected in series. When the first puncture needle exactly punctures at this puncture point, the series circuit is conducted, so that the first indicator light lights up.

[0079] In clinical operations, for any one of the somatic nerve tissue operation skills and peripheral nerve block operation skills targeting nerve regions, a second indicator light is connected and set at the block point of the bionic target operation site model. When the second puncture needle punctures to this block point and reaches the corresponding nerve, the second indicator light is lit to indicate the success of the corresponding nerve block operation.

[0080] Specifically, the block point, the second indicator light, and the second puncture needle are connected in series. When the second puncture needle exactly punctures at this puncture point, the series circuit is conducted, so that the second indicator light is lit.

[0081] The model construction method adopting the solution of the present invention can obtain various types of models, including models for providing PICC insertion operation skills, models for providing pulmonary artery catheter insertion operation skills, models for providing arterial puncture operation skills, models for providing central venous puncture operation skills, models for providing intraspinal puncture operation skills, models for providing caudal puncture operation skills, models for providing somatic nerve block operation skills, and models for providing peripheral nerve block operation skills. By using these models, the safety and quality of medical services can be improved.

[0082] In addition, during the training of using the Icare device to evaluate intraocular pressure, the eyeball can also be scanned to obtain medical image data of the eyeball. Based on the medical image data of the eyeball, an eyeball model is constructed, which specifically includes main anatomical structures such as the anterior chamber, posterior chamber, iris, and lens. Among them, the pressure response of the cornea is mainly constructed. Specifically, by adding a small pump and a pressure sensor to the cornea, different hardnesses of the cornea are simulated, so as to simulate different intraocular pressure conditions. In this way, when training to use the Icare device to evaluate the intraocular pressure of patients, by changing the intraocular pressure conditions, it is convenient for trainees to measure various intraocular pressures.

[0083] One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

Furthermore, by providing a real bionic model, it is provided to clinical trainees for clinical operations, reducing operation risks and enabling clinical trainees to quickly master clinical operation skills.
