Embodiment 1
[0045] Example 1: A 3D printed personalized plunger puncture treatment (dispersed guide hole) template with a fixing device
[0046] Follow the steps below to prepare the puncture needle dispersion guide hole template:
[0047] (1) Collecting data: Scan enhanced CT of the preoperative postoperative position to obtain thin-layer CT data of the lesion area, input the CT scan data into the preoperative planning software, and formulate the puncture needle path according to the tumor size, position and the relationship between peripheral blood vessels and nerves. The number of puncture needles required is calculated and numbered, and the spatial coordinates of each puncture needle are recorded according to the number.
[0048] (2) 3D design modeling: Import CT data into 3D modeling software, reconstruct the contour of the human body surface and expand it by 3-5mm to form a template substrate. Enter the puncture needle space coordinates into the 3D modeling software according to the number...
