3D bio-printing inside the human body could be possible thanks to a new soft robot. The device featuresprinting head directly mounted onto the tip of a soft robotic arm. This printing head, consists of soft artificial muscles that allow it to move in three directions,works very(similar) to conventional desktop 3D printers.
The soft robotic arm van bend and twist and can be made at any length (require), The printing nozzle(喷嘴)can be programmed to print per-determined shapes,or operated manually; addition, a research team used a machine learning-based controller which can aid the printing process.
The team(explain)how the device could potentially be used as an all-in-one surgical tool to perform a range of(function). They said this could be especially important in surgery(remove) certain cancers.
The ability to carry out such multi-functional procedures(demonstrate) on a pig's intestine(肠) last month and the researchers say the results show that the device is a(promise)candidate for the future development of an all-in-one endoscopic surgical tool. The next stage of development for the system is in vivo(活体的)testing on living animals to demonstrate its practical use.
