A team of biomedical engineers based at the University of Sydney has developed a new low-cost method for manufacturing bone replacement implants for severely damaged skulls.
In collaboration with the Sydney Neurosurgery Group, a new 3D printing technology has been developed that allows doctors to get patient-matched implants within a few days instead of the weeks spent.
Dr. Phillips-Laboratory and Project Director said that severe head trauma can lead to significant skull healing, and the current treatment process requires surgeons to stretch and suture excess skin around the wound and wait for a suitable implant. And the rapid prototyping of their application templates makes it possible to create patient-safe, sterile, sterile skull implants. Simply take a picture of the patient's head and use a polymer-based "bone cement" to make it in a matter of days.
The rapid stencil technique of the skull implant is not only faster, it is cheaper than the previous method of matching the patient's anatomy to make a replacement. Team members indicated that existing 3D printed implants are still weak because they may be contaminated, leading to a higher risk of infection or inflammation. With this new technology, we were able to create a sterile template of the damaged area of ​​the patient and then apply the biocompatible polymer bone cement to the patient's specific template in a sterile environment to produce its personalized implant. Object. This groundbreaking technology has been successfully used in several patients.
Not long ago, a group of scholars from the University of Tokyo in Japan also publicly stated that they are studying 3D printing technology to create personalized bones and articular cartilage - using artificial proteins and calcium phosphate to simulate the composition of real bones and cartilage, printing "CT- Bone, used to insert a broken bone, or implanted with a bone defect, acting as a scaffold to support the growth of new bone.
3D printing technology has begun to be used in the field of clinical medical research. With this pen, maybe the doctor can become Ma Liang in the future.
