3D print facial reconstruction!Can Lin Zhiying's "not old god face" recover?

Lin Zhiying, the Asian male god, who once had an old -fashioned Asian male, is currently facing the risk of disfigurement. On July 22, Lin Zhiying had a car accident while driving Tesla Model X. According to reports, the accident caused Lin Zhiying's face fracture and mounting fracture of the humerus.

However, Lin Zhiying may carry out "3D printing technology for face reconstruction." Can this sound of a sense of technology full of technology restore "not old -fashioned"?

Can you return to "Shengshi Beauty"

According to reports, Lin Zhiying's face facial reconstruction plan may be that a large part of the skeleton on the face will be implanted through titanium alloy, and another part of the more fine bones will be rebuilt through 3D printing technology. Grow in and integrate the implant with the bones.

Although implanting metal and artificial models into the human body sounds a bit appalling, 3D facial reconstruction has already had many application cases in medicine.

It improves the accuracy and stability of doctors' surgery, and helps many patients who are disfigured by accidents or diseases to reshape the "second face" in life and return to the lives of normal people.

This technology has achieved mature development abroad. For example, as early as 2015, a man Richard Stratton from Australia had undergone 3D facial reconstruction surgery, becoming the first person in human history to have a 3D printed titanium alloy chin.

According to the doctor's description, Lin Zhiying took about 10 hours to complete this facial reconstruction surgery. Such surgery is a coordinated surgery of multi -department rooms, 3 to 4 doctors such as plastic surgery, neurosurgery, otolaryngology, and other 3 to 4 doctors perform surgery for patients.

Some experts speculate that Lin Zhiying may use a 3D printing skull model for doctors to judge, or 3D made a fixed bracket for titanium alloy to fix the fragmented bones.

The popularization of 3D printing technology

Use 3D printing technology to make templates, and on this basis, it has been widely used clinically. Especially the oral and maxillofacial surgery, because the skeleton of the face is arc, and the precise requirements are high, so it is also very suitable for 3D printing technology.

Deputy Chief Physician Li Huaiqi, a dental and maxillofacial surgery in Jiangsu Province, said that 3D printing is an industry that has developed rapidly in the medical field for more than a decade. It is a product of the development of biological organization engineering, material science, computer image and other technologies. "For example, the patient's face defects, the traditional repair is the doctor's" feeling ', according to his own experience, compare the appearance of the other side to complete this side repair. But after the computer digital technology, we we we have, we we have, we have a computer digital technology. You can import the patient's photos, CT, or magnetic resonance data to the system, and the computer can complete the reconstruction work. "After the reconstruction, the 3D printing technology can be used to use titanium or other polymer materials. In the shape of the bone, patients can intuitively see the repair effect, and the doctor's repair also has a template.

Director of the Director of Plastic Surgery of Zhongshan Hospital Affiliated to the School of Medicine of Fudan University also said that the most clinically applied 3D technology is that when patients are defective in bone accidents due to car accidents and tumors What is the defect of the bone?

Around 2015, the Shanghai 411 All -Army Oral Center printed a section of mandibular implantation into the human body through 3D, which is the first 3D printed mandibular implant surgery in the country.

In 2019, the "chin" joint with 3D printing polyetherone ketone materials with 3D printed polyether ether is the world's first case of 3D printing of mandibular joint implantation.

Jiangsu Provincial Stomatology Hospital also completed 3 cases of 3D printed mandibular implant surgery around 2020, and all 3 cases were successful.

At present, 3D printing is used to help facial reconstruction. In fact, it has been used clinically, but 3D prints "bones and tissues" directly into the human body, and more in clinical exploration. This "bone" directly implanted into the human body is very expensive, and the "volume" of the mandible may spend more than 100,000 yuan. In addition, 3D printed materials are currently not compared with native bones, such as attached muscle nerve blood vessels and control exercise completion functions. Experts said that there is still a long way to go.

Exploration of 3D printing technology

At present, scientists in various countries are also actively exploring the application of 3D printing technology in the field of complex organic organisms with "life", such as through artificial extracellular matrix 3D printing blood vessels, trachea, heart, kidneys, liver, etc., and breakthroughs from time to time The results entered the public vision.

If the field enters the application stage one day, if 3D printing can really achieve complex organs, then organ transplantation will no longer depend on living bodies, and many diseases will no longer be a problem. Let's look forward to this day together.
