#More revealed about 3d printed Acetabular Cup formally approved for hip surgery in China Chinese scientists
and surgeons have been at the forefront of 3d printed medical applications over the last few years,
and regular readers will have noticed doubtlessly a lot of 3d printed components being used in surgeries in Chinese hospitals.
and Cai Hong of Peking University Third Hospital in cooperation with AK Medical, a Chinese private medical company.
joint replacement surgery is very common in China about 400,000 took place in 2014, of which at least two thirds is focused specifically on hip replacement.
From his long-term clinical experience in the medical field Zhang Ke realized that it can be used widely in medical applications.
After returning to China, he received support from Liu Zhongjun, Director of the bone department at the Beijng University Third Hospital.
For the next step, Zhang Ke began leading the Group of Orthopedic Joints team to develop the first Chinese 3d printed hip products.
Cai Hong explained after leading the revision surgery which cost the patient another 100,000 yuan (after paying 40,000 for the previous surgery).
The difference is that the common cast cup has a smooth surface, while the 3d printed version is rough
So far, dozens of patients have received 3d printed hip replacement surgery, and ll the clinical results were very good,
Also problematic is printed that 3d customized orthopedic implants are restricted still officially in use. Cai Hong expressed regret that, at the present,

#3d Systems Demos Virtual Surgeries and Soft 3d Printed Models in New orleans On top of its massive 3d printing portfolio and Quickparts services, 3d Systems also has an extensive medical design
Today, the company has announced two significant programs that could foreshadow the future of medicine altogether:
the release of irst-ever virtual reality robotic prostatectomy simulation training as well as patient-specific 3d printed kidney models for surgical planning and training, developed in partnership with Tulane University School of medicine.
To step in and train the surgeons that will perform this surgery is 3d Systems with its Robotix Mentor training module.
The Robotix Mentor allows trainees to practice the surgery in a virtual environment using step-by-step guidance, performance metrics, anatomy recognition,
The additional LAP Mentor Express simulator even provides laparoscopic assistants training to aid the primary surgeon in the virtual procedure. 3ds Vice president
he addition of the Prostatectomy Module changes the future of Robotic Urology training. 3d Systems is committed to supporting medical advancements that ultimately affect patient safety by providing innovative products that range from virtual reality training
In addition to their new Robotix system, 3ds has developed also a new series of soft, 3d printed kidney models for surgical training.
the models developed by 3ds in tandem with surgeons at Tulane University School of medicine actually have the texture and consistency of the kidneys on

ndividualized patient-specific soft tissue 3d printing allows surgeons and trainees the opportunity to operate on a model that looks
and feels just like their patient kidney tumor. This technology has the potential to reinvent the way we teach
and train our young surgeons and for experienced surgeons adapting to a new technology such as robotics,
