Since the introduction of 3D printing technology in the medical field, its advantages such as high precision, high degree of reduction, and high work efficiency have been well received by medical personnel.
Integration of medical field and 3D printing technology
Currently, 3D printing technology has four research directions in the medical field: in vitro medical device manufacturing, personalized permanent implants, tissue 3D printing, and cellular 3D printing.
In in vitro medical device manufacturing, 3D printing can print a medical model 1:1 based on the scan data provided by the imaging device. Not only can it be used as a surgical model, allowing doctors to perform surgery on it beforehand, to determine precise surgical points before surgery, and as a best practice material for teaching and medical training.
In addition to in vitro medical device manufacturing, 3D printing technology has made some progress in the printing of personalized permanent implants. Especially in the field of maxillofacial repair and orthopedics.
The 3D printed heart and liver belong to the tissue and cell fields and have not entered the clinic. Although it can be printed, it does not have the same functional function as the original organs of the human body. In particular, cell 3D printing, printing printed cells and liposuction materials, layer by layer, extruded into a shape, like jelly, and can grow with the original tissue of the human body, is still under study, otherwise only It doesn't make sense to be able to exist for hours. â€
Approval can't keep up with the pace of technology
Although the prospects for 3D printing in the medical field are very beautiful, many medical staff have expressed the same concern: how to get product approval quickly is a problem.
Because 3D printed medical device products are very personalized, it has surpassed the existing medical device product supervision operation mode. It is impossible for every printed product to be inspected. Some researchers have previously exchanged opinions with relevant department heads to solve ideas. Look at the product line and production technology.
A scientific researcher who does not want to be named also said that the exchange of opinions may just be said, and there is no intention to solve it. The challenges brought by the new technology to the traditional management model have not been seriously taken by the relevant departments.
