Objective To verify the minimally invasive surgical approach and therapeutic effects of using the medical neurosurgery robot Remebot to treat hypertensive intracerebral hemorrhage (HICH). Methods Clinical data for 17 HICH patients were analyzed retrospectively. Hematoma evacuation and tube drainage using Remebot frameless stereotaxic techniques were performed for all patients, and urokinase was injected into the hematomas after the operations. Results Robot‐assisted stereotactic techniques can accurately guide hematoma punctures, and no deaths occurred among these patients. The average positioning error was 1.28 ± 0.49 mm. The average drainage duration was 3.4 days. The 3‐month postoperative follow‐up revealed improved neurological functions and quality of life for all patients. Conclusions The medical neurosurgery robot Remebot is minimally invasive, has high positional accuracy, and facilitates surgical planning according to the shape of the hematoma. Therefore, robot‐assisted surgery using Remebot represents a safe and effective treatment method for hematoma evacuation and tube drainage in HICH patients.

The properties exhibited by Ni-rich cathode materials were enhanced through the mixed coating layers of Li 3 PO 4 and boric acid. The scanning electron microscopy (SEM), the transmission electron microscope (TEM), the differential scanning calorimetry (DSC), the Electrochemical Impedance Spectroscopy (EIS), as well as the half-cell and full-cell charge-discharge tests were adopted for characterizing the structure and electrochemical properties exhibited by the cathode materials. As revealed by results, the Li 3 PO 4 and boric mixed coating layers can effectively reduce the surface area and protect the direct contact between cathode material particle surface and electrolyte, meanwhile improving the structural stability and cycle performance. The coating of fast ionic conductor contributes to enhance the specific capacity possessed by the Ni-rich cathode materials accordingly.
