Embodiment Construction

[0024] see Figure 1 to Figure 4 shown:

[0025] The method of applying 3D printing technology to manufacture a human transparent spinal canal cavity provided by the present invention comprises the following steps:

[0026] The first step is to measure and obtain the human spinal canal lumen data through computed tomography, that is, CT. The specific steps are as follows:

[0027] Step 1. Spinal canal curvature: obtain a cross-sectional view of the sagittal centerline of the human lateral full spinal canal. The value of Y-axis is accurate to 1mm; the value of X-axis: a horizontal line is established from the midpoint of the anterior wall of the spinal canal of each vertebral body to the Y-axis, and the measured value is used as the value of X-axis. The value of X-axis is accurate to 0.01mm, and each horizontal line is marked with Y The axis end is zero, and the connection line at the front wall of the spinal canal can display the curvature of the spinal canal. The curvature...

Abstract

The invention discloses a method for manufacturing transparent spinal canal cavity of human body by using 3D printing technology. The software generates 3D images according to the above-mentioned measured data; the third step is to input the above-mentioned 3D printing data of the spinal canal cavity into the 3D printer, and use transparent polyester material to generate the transparent spinal canal cavity of the bionic human body through 3D printing. Beneficial effects: the transparent spinal canal cavity of the bionic human body provided by the present invention can observe and study the pharmacokinetics of anesthetics with obvious colors in the spinal canal cavity under direct vision when it is filled with bionic colorless cerebrospinal fluid, and obtain anesthesia Quantitative research data and technical training for plane control. It can not only carry out quantitative research on the control factors of the subarachnoid anesthesia plane, but also provide extremely beneficial help for anesthesiologists and medical students in medical schools to train on the control factors of the anesthesia plane.

Description

technical field [0001] The invention relates to a method for manufacturing a human transparent vertebral canal lumen, in particular to a method for manufacturing a human transparent vertebral canal lumen by applying 3D printing technology. Background technique [0002] At present, subarachnoid nerve block is an important clinical anesthesia technique. The principle is: puncture the intervertebral space below the second lumbar vertebra, after the tip of the puncture needle enters the subarachnoid space, tightly connect the syringe containing the anesthetic liquid to the end of the puncture needle, push the syringe, and the anesthetic liquid in it is injected into the puncture needle. in the cerebrospinal fluid in the subarachnoid space. The diffusion range of the anesthetic liquid in the cerebrospinal fluid (anesthesia plane: the anesthetic liquid has an anesthetic effect on the nerve roots and spinal cord within the immersion range.) It is determined by the following factor...
