China's National Medical Products Administration has recently approved the registration application for an implantable brain computer interface for hand motor augmentation.
It is an invasive brain computer interface medical device developed by Neurical Technology Shanghai Company.
Dubbed NEO.
The equipment is intended for patients aged 18 to 60 who suffer from quadriplegia caused by cervical spinal cord injuries and are unable to perform grasping movements with their fingers by implanting a coin-sized invasive device.
It can collect and decode patients' brain signals in real time, enabling them to control a pneumatic glove through brain signals to perform actions such as grasping objects, picking up items and drinking water.
The product adopts an epidural implantation approach to ensure a high signal-to-noise ratio in brain signal acquisition, while avoiding direct damage to brain tissue.
Its wireless power supply and communication design allow for a single implantation with long-term use.
So far, the device has been used in 36 clinical procedures, including four feasibility trials and 32 multi-centre good clinical practice clinical trials.
All participating patients experienced varying degrees of improvement in grasping function and some exhibited signs of neural remodeling and regaining certain neural functions.

China has unveiled its first school of space exploration to cultivate more leading talents in the aerospace field.
Established by the University of Chinese Academy of Sciences.
The school will focus on cutting-edge fields such as interstellar propulsion, deep space communication and navigation, and space science.
It aims to cultivate urgently needed interdisciplinary professionals.
Zhu Junxiang, an academician of the Chinese Academy of Sciences and the school's dean, said it aims to become a key base for foundational aerospace research to support major national projects.
It will also serve as a hub for cultivating high-level talent capable of pioneering exploration, and a Centre for International Academic Exchange to share China's expertise through solid achievements.
The establishment of the new school is a key move by the University of Chinese Academy of Sciences to promote the integrated development of education science, technology and talent.
It also addresses a critical shortage of specialized professionals.
A team of Chinese researchers has developed a new high-speed 3D printing technology capable of achieving high-resolution printing of millimeter-scale complex objects in just 06 seconds.
This sets a new record for 3D printing speed.
That is according to a study published in the journal Nature.
As an essential tool for scientific research and industrial manufacturing.
3D printing has long faced challenges in balancing speed and precision.
High-resolution printing of millimeter-scale objects often takes tens of minutes or even hours, making it difficult to meet the demands of scientific research and production.
Dai Chunhai, an academician of the Chinese Academy of Engineering, led a team from Tsinghua University focusing on computational optics.
They discovered that computational optics can not only capture light field information, but also manipulate high-dimensional holographic light fields to construct three-dimensional entities.
This offers a novel approach to improving 3D printing.
After five years of research, the team ultimately developed the digital incoherent synthesis of holographic light fields 3D printing technology.
Experiments show that this technology can complete the fabrication of millimeter-scale complex structures in just 06 seconds.
It achieves a minimum printable structure size of 12 micrometers and a printing rate of up to 333 cubic millimeters per second.
According to Wu Jianmin, one of the paper's corresponding authors, the new technology overcomes the speed limitations of point-by-point or layer-by-layer scanning methods.
It enables the precise projection of complex 3D light intensity distributions in an extremely short time and achieves rapid object printing.
Another advantage of this technology is its minimal requirement for the printing container, needing only a single optical flat surface without any special structural design.
Moreover, The container remains stationary throughout the printing process, without the need for high precision relative motion between the container and the probe, as required by traditional methods.
According to Dye,
The technology could be applied in the mass production of micro-components such as photonic computing devices and mobile phone camera modules.
It can also produce parts with sharp angles and complex curved surfaces.
In the future, it may expand its applications to complex scenarios such as flexible electronics, micro-robots and high-resolution tissue models.
The China Theatre Association has announced a plan to provide increased support for the country's rare opera genres.
These are practiced in limited regions compared with mainstream forms like Peking Opera and Quenchu.
The Association, a national organization for theatre professionals, including playwrights directors, actors and critics, has unveiled this plan at a symposium in Beijing.
This is part of a broader initiative to promote the development of theatre arts.
According to the association, the plan aims to expand the audience base and enhance the influence of rare opera forms.
This will be achieved through measures such as staging showcase performances of outstanding productions.
The Theatre Art Promotion Program also outlines efforts to improve the quality of playwriting.
It will facilitate direct access to high-quality theatre resources at the grassroots level.
And it will establish flagship youth theatre activities nationwide.
That is the end of today's programme.
