Tumor-reductive surgery exercise model and manufacturing method thereof

Abstract

The invention relates to the field of medical models of human bodies, in particular to a tumor-reductive surgery exercise model and a manufacturing method thereof. The tumor-reductive surgery exercise model comprises a surgical organ thin wall model and a three-dimensional tumor model, wherein a connection piece is connected between the surgical organ thin wall model and the three-dimensional tumor model; a transparent colloid body is arranged in the surgical organ thin wall model. The manufacturing method of the tumor-reductive surgery exercise model comprises the following steps of: 1, acquiring a CT image or an MR image of a patient, and performing three-dimensional reconstruction; 2, obtaining the surgical organ three-dimensional model; 3, hollowing the surgical organ three-dimensional model; 4, obtaining the three-dimensional tumor model in a surgical organ; 5, constructing a surgical organ exercise model; 6, printing the surgical organ exercise model in a 3D form; and 7, manufacturing the surgical organ exercise model. The manufacturing method disclosed by the invention can be used for manufacturing the model capable of really simulating a surgical organ tumor of the patient, and the model is convenient to teach, operate and exercise.

Description

technical field [0001] The invention relates to the field of human medical models, in particular to a tumor resection operation practice model and a manufacturing method thereof. Background technique [0002] Benign / malignant tumors in various organs have become a class of frequently-occurring diseases in modern people. Because tumor resection in organs is very complicated and there are a large number of nerves, blood vessels, and lymph nodes nearby, a lot of practice and observation are required to accumulate sufficient clinical experience before performing surgery on patients. [0003] At present, the sources of surgical practice for interns are usually various animals. However, the organ structure of animals is quite different from that of the human body, so the practice effect is not good; moreover, autopsies are performed, but the sources of cadavers are very few, which is difficult to meet the needs of practice. Physicians are in great demand; and because it is diffic...

Problems solved by technology

[0003] At present, the sources of surgical practice for interns are usually various animals. However, the organ structure of animals is quite different from that of the human body, so the practice effect is not good; moreover, autopsies are performed, but the sources of cadavers are very few, which is difficult to meet the needs of practice. Physicians are in high demand; and the above two exercises are not suitable for novice physicians to practice surgery due to the difficulty of seeing inside the organs

[0004] Furthermore, CT or MR scans are usually used for the preoperative examination of tumor patients at present. Due to the layer-by-layer cross-sectional images, even the chief surgeon cannot fully see the patient's condition from the images, and only those who have received professional training Only a few radiologists can understand the meaning of the image, and because the image is not intuitive enough, in many cases, the interpretation of the scan image of the same patient in different hospitals is subjective, and the evaluation of the condition obtained is discrepant.

This has seriously affected the surgical decision-making and surgical strategy selection of the surgeon and the patient's family.
