Problems solved by technology

In clinical training, most domestic hospitals and medical device manufacturers use beef to simulate human tissue. Although the tissue is close to the gland, due to its opacity, learners and observers cannot intuitively see the lesions, glands, and Positional relationship of the puncture needle
At present, there is no similar glandular phantom that can solve the problem in China. Therefore, it is necessary to develop a transparent phantom that is similar to the human body, to overcome the disadvantages of invisible lesions in the past, and to make the mammography-guided puncture more intuitive and easy to understand. study

Embodiment 1

[0019] A phantom for clinical training of breast microcalcification, comprising a phantom shell, simulated gland tissue filled in the phantom shell, and several simulated calcifications, the phantom shell is made of polyethylene material, and the simulated gland The tissue is a composition of gelatin powder and purified water with a mass ratio of 1:10, and the simulated calcification is small steel balls or eggshell substances.

[0020] The preparation of the phantom for clinical training of breast microcalcification is as follows:

[0021] 1) Weigh the gelatine powder and purified water according to the mass ratio, first put the gelatine powder into a container, heat and stir in a water bath at 80°C until fully melted, then mix the purified water with the melted gelatin powder, and stir evenly , to get the mixed solution for subsequent use, the density of the mixed solution is 1.04g / ml;

[0022] 2) Measure the position of the lesion in the mammary gland according to the mamm...

Abstract

The invention provides a body model for clinical training of breast microcalcification and preparation of the body model. The body model comprises a model body housing, simulated gland tissue and a plurality of simulated calcium compounds, wherein the model body housing is filled with the simulated gland tissue and the plurality of simulated calcium compounds; the model body housing is made of a polyethylene material; the simulated gland tissue is a composition of gelatin powder and purified water at the mass ratio of 1:10; and the simulated calcium compounds are small steel balls or eggshell materials. According to the invention, three-dimensional positioning puncture biopsy can be simulated; by adopting a transparent body model, the defect in the prior art that a lesion cannot be seen is overcome; breast puncture under X-ray guide is more intuitive; the lesion (namely the small steel balls or eggshell materials) taken out from the body model is convenient to understand and learn; and the body model can be repeatedly used, so that resources are saved.

Description

technical field [0001] The invention relates to medical training equipment, in particular to a phantom for clinical training of breast microcalcification and its preparation. Background technique [0002] The incidence of breast cancer is increasing year by year, which seriously threatens women's health. The advantage of mammography is to find small and clustered calcifications with malignant potential. Digitalization is performed for patients with tiny calcifications in the breast, clinically inaccessible masses, and negative ultrasound Mammography-guided needle biopsy, this method has accurate positioning, complete resection, and less glandular damage during the operation. In clinical training, most domestic hospitals and medical device manufacturers use beef to simulate human tissue. Although the tissue is close to the gland, due to its opacity, the learners and observers cannot intuitively see the lesion, the gland, and the The positional relationship of the puncture ne...
