用4D打印治疗乳腺癌  

A Chinese hospital announced on Tuesday that doctors have recreated a breast for a cancer patient using 4D printing.
The surgery was performed on August 8
2016
and the printed breast has grown well with the patient's own tissue
said Ling Rui
a vascular surgery doctor with Xijing Hospital of the Fourth Military Medical University in Xi'an
Shaanxi Province.
The patient underwent a mastectomy for her left breast last year
before having the surgery.
去年在进行这一手术之前，这位病人进行了左侧乳房切除手术。
"Compared with three-dimensional printing
4D printing adds time as another dimension
" said Ling.
Doctors collected data on the size of her tumor and original breast
and reconstructed a bio-degradable breast.
The implant was developed by the hospital with a national lab of Xi'an Jiaotong University.
"It is sufficiently strong
and will degrade in designed period of time
which is in the patient's case one to o years
" said Zhang Juliang
an assistant professor in Xijing Hospital who participated in the surgery.
Its porous nature allows human tissue to grow into the implant and ultimately replace it
Zhang said.
"In the ten months since the surgery
the implant has grown well
and the patient's veins and tissue have started to grow back
" Ling said.
Compared to existing methods of breast reconstruction
the method has fewer side-effects
Ling said.
