On December 25th, the neurosurgical robot developed by Huake Precision (Beijing) Medical Technology Co., Ltd. was officially approved by the National Drug Administration (NMPA) and became the first neurosurgical robot to be approved by the National Innovation Review. It marks that China's neurosurgical robots have reached the international leading level. This product is also the first neurosurgical robot in China that is suitable for both children and adults. It not only fills the gap in China, but also becomes an innovative medical device with international competitiveness.
Special approval for national innovative medical devices in 2017
Huake precision neurosurgery robot technology originated from Tsinghua University, from Tsinghua University and Tiantan Hospital, Xuanwu Hospital, Peking University First Hospital, Tsinghua University Yuquan Hospital, Shenzhen University General Hospital, Fushan University affiliated Huashan Hospital, Fudan University Affiliated Pediatric Hospital, A new generation of internationally advanced robots jointly developed by the Capital Pediatric Research Institute, Peking Union Medical College Hospital, Third Affiliated Hospital of Southern Medical University, Fujian Union Hospital, Second Hospital of Hebei Medical University, and First Affiliated Hospital of Zhengzhou University The system was developed and produced by Huake Precision (Beijing) Medical Technology Co., Ltd. In 2017, it passed the special approval channel for innovative medical devices of the State Food and Drug Administration. In 2018, it was selected as “Zhongguancun Demonstration Zone High-tech Industry Cultivation Projectâ€.
Clinically suitable for both adults and children
Huake precision neurosurgery robot is mainly used for the positioning and orientation assistance of surgical instruments in stereotactic surgery of neurosurgery, such as stereotactic electrode placement of epileptic brain, deep electrode placement of Parkinson's brain, and biopsy of brain tumor. The product not only has important significance in the field of adult neurosurgery, but also fills the gap in the field of pediatric neurosurgery in China because of its substitute effect on traditional headgear and traditional surgical navigation and positioning system, which is of great significance to the overall development of neurosurgery in China.
Independent technology has international leading level
Compared with the international level, Huake Precision Neurosurgery Robot has a leading edge in accuracy and safety.
In terms of product accuracy, this product is based on the current international advanced technology system. We use the contactless visual positioning patient registration technology, based on the mechanical arm body positioning method, using automatic visual scanning to locate the patient's facial surface for patient registration. This product makes the neurosurgery robot suitable for both adults and children for the first time in China. This technology belongs to the international leading and domestic initiative. The advantage is that the independent positioning system existing in the traditional optical positioning adopted in this aspect in China increases the system complexity, relies on three registration points, and has a large registration error, and it is cumbersome to scan the CT process on the day of surgery. And other issues.
In terms of product safety, we have developed a three-dimensional visualization technique for craniocerebral vessels based on multimodal image fusion for the actual clinical features of neurosurgical orientation. This technique can fully display the intracranial vascular structure. Effectively help doctors avoid the important vascular planning puncture path, thus forming a safe, targeted, personalized and optimized stereotactic surgery program. This technology is internationally leading and has been well received by domestic clinical applications.
Accurate, reliable, safe and easy to use
Huake precision neurosurgery robot provides reliable precision for neurosurgical stereotactic surgery. The overall surgical precision is less than 1mm, and the repeatability is less than 0.02mm. The products include the world's leading stereotactic surgical planning system, high intelligent vision positioning system, high precision force sensing system and high stability manipulator system.
The Stereotactic Surgical Planning System makes it possible to design each surgical path with ease and excellence with its unique multimodal image fusion technology and unparalleled revascularization technology.
The high-intelligent visual positioning system automatically scans the skin surface by using a high-precision camera to form a scanning point cloud, and then performs three-dimensional surface registration of the robot and the actual human body surface, and uses a unique algorithm technology to greatly improve the accuracy. At the same time, the computer vision system also automatically acquires and establishes the actual patient skull model and environmental obstacle model, and obtains the best obstacle avoidance path through the automatic optimization algorithm, so that the robot can move safely and efficiently to the designated planning position, and has no contact with the patient.
The high-precision force sensing system uses the exclusive gravity compensation algorithm to monitor the mechanical force of the arm in real time. When the force is abnormal, the system automatically stops and the reaction time is less than 30ms, which provides an effective closed-loop safety guarantee for the robot. The high-stability manipulator system uses joint brakes and RV reducer technology to ensure high stability and immunity.
The RNA purification kit is used to purify and recover RNA molecules transcribed in vitro and total RNA extracted from various materials, which can effectively remove contaminating impurities in RNA samples. The recovery rate of this product can reach 80%, and the OD260/OD280 ratio of the obtained RNA is generally about 2.0, which can be directly used in subsequent sensitive experiments (such as microarray analysis, fluorescence RT-PCR, etc.). With the deepening of transcriptomics, the complexity of RNA types, expression regulation and functions is far beyond our imagination.
Removing ribosomal RNAs that account for more than 80% helps to focus sequencing on less abundant but informative RNAs. At present, the removal of rRNA is mainly through the combined use of probe and RNase H. The processed RNA will be mixed with many digestion products, enzymes and ions, which is not conducive to the subsequent construction of RNA library. Take the Columnar RNA Purification Kit as an example. Trizol is a ready-to-use reagent that can be used to purify total RNA from tissues and cells. This is a single-phase solution of phenol and guanidine isothiocyanate that facilitates lysis of tissues and cells, inhibiting RNases to maintain RNA integrity.
