Portable positioning mechanism towards robotic needle intervention

Needle surgery systems that are manually led by surgeons often require high levels of surgeons' expertises and patients’ condition, while being limited by lower precision and repetitive injuries from multiple needle insertions. Existing robotic surgical needle insertion systems, in turn, are often limited by their large size and poor MRI compatibility, thus lacking a wide range of application scenarios. The portable needle positioning robot developed in this project is portable, compact, and NMR-compatible. In practical experiments, it has greatly reduced the setup time of the robotic surgical platform and achieved accurate end-positioning, while having good NMR compatibility. These capabilities allow the robot to be rapidly deployed in response to different surgical situations and enable faster and safer surgical procedures, greatly reducing surgeons’ stress and patients’ suffering. The good MRI compatibility allows the system to integrate multiple environmental information. With the help of artificial intelligence, the system can intermingle multiple information and obtain more powerful complex surgical processing capabilities.
