Embodiment 1
[0031] refer to figure 1 As shown, the present invention discloses a surgical template manufacturing device based on three-dimensional modeling, which is used to manufacture a surgical template. The surgical guide includes a guide body, a positioning column located on the guide body, and a positioning identification hole. The device includes a control computer 1, Microprocessor 2 and 3D printer 3, wherein:
[0032] A three-dimensional modeling system 11 and a surgical operation simulation system 12 are installed on the control computer 1, wherein:
[0033] The three-dimensional modeling system 11 establishes a human organ tissue model including organs, lesions, blood vessels, hard tissues, and skin based on CT images. The organs, lesions, blood vessels, hard tissues, and skin in the human organ tissue model can be individually set and Transparent treatment. The three-dimensional modeling system 11 includes a CT image import unit, a CT image segmentation unit, and a modeling ...
Embodiment 2
[0039] refer to figure 2 As shown, the present invention discloses a method for making a surgical guide based on three-dimensional modeling, which is implemented based on the device for making a surgical guide in Embodiment 1, which includes the following steps:
[0040] S1. The three-dimensional modeling system 11 establishes a human organ tissue model including organs, lesions, blood vessels, hard tissues and skin based on CT images. This step is achieved through the following sub-steps:
[0041] S11, using the CT image importing unit to import the CT image;
[0042] S12. Using the CT image segmentation unit to segment organs, lesions, blood vessels, hard tissues, and skin on the CT image;
[0043] S13. Using the modeling unit to establish three-dimensional models of organs, lesions, blood vessels, hard tissues and skin, and fuse them into human organ tissue models.
[0044] S2. The surgical operation simulation system 12 imports the human organ tissue model and performs...
Embodiment 3
[0050] Since the surgical guide directly acts on the patient's surgical site, the printed surgical guide is required to be aseptic to prevent infection. However, due to the slow speed of 3D printing, it is usually necessary to arrange the printing work several hours or even days before the operation. Therefore, there is a large interval between the time when it starts printing and the time it is used, and it is difficult to use traditional 3D printers. To meet the requirements of sterility, at the same time, how to store it after printing is a problem. If it is always placed in the 3D printer, the utilization rate of the 3D printer will be low. Therefore, the 3D printer is preferably modified in this embodiment.
[0051] Please refer to image 3 , Figure 4 and Figure 5 As shown, a 3D printer includes a printing chamber 1 , a storage chamber 2 , a tray 3 , a cleaning device 4 and a push rod 5 .
[0052] Wherein, the printer chamber 1 includes an XY-axis feeding device 11 ...
