    Abstract: A novel uncoupled and isotropic 2-degree-of-freedom parallel mechanism is presented in this article. The parallel mechanism consists of two kinematic chains: R-4R-R kinematic structure and R-R-P-R-R kinematic structure. The x-axis and y-axis projective angles of the output linkages can be actuated by the corresponding motor mounted on the fixed base. Forward kinematic, inverse kinematic, uncoupled, and isotropic characteristics of the parallel mechanism are analyzed. Singularity analysis and workspace analysis are achieved. The uncoupled and isotropic architecture of the parallel mechanism has some merits such as the larger workspace, a simple mathematical treatment, an easy control, high stiffness, and dexterity. The parallel mechanism can be applied in fields that require aiming at subjects, such as the use of machining tools, radar scanners, telescopes, cameras, satellite solar arrays, the human wrist, and minimally invasive surgery.

    Abstract: Seizures are a common symptom of craniocerebral diseases, and epilepsy is one of the comorbidities of craniocerebral diseases. However, how to rationally use anti-seizure medications (ASMs) in the perioperative period of craniocerebral surgery to control or avoid seizures and reduce their associated harm is a problem. The China Association Against Epilepsy (CAAE) united with the Trauma Group of the Chinese Neurosurgery Society, Glioma Professional Committee of the Chinese Anti-Cancer Association, Neuro-Oncology Branch of the Chinese Neuroscience Society, and Neurotraumatic Group of Chinese Trauma Society, and selected experts for consultancy regarding outcomes from evidence-based medicine in domestic and foreign literature. These experts referred to the existing research evidence, drug characteristics, Chinese FDA-approved indications, and expert experience, and finished the current guideline on the application of ASMs during the perioperative period of craniocerebral surgery, aiming to guide relevant clinical practice. This guideline consists of six sections: application scope of guideline, concepts of craniocerebral surgery-related seizures and epilepsy, postoperative application of ASMs in patients without seizures before surgery, application of ASMs in patients with seizures associated with lesions before surgery, emergency treatment of postoperative seizures, and 16 recommendations.

    Abstract: In the minimally invasive surgical robot system, the surgeon controls the movement of instruments with master manipulators, which is a typical physical human-robot interaction system. In this paper, the surgeon is fully taken into consideration for structural design optimization. The kinematics model of the surgeon’s arm was established to describe the irregular shape of surgeon’s operation space; The surgeon console model was established to describe the relative position between the master manipulators and the surgeon’s arm. To make master manipulator could behavior great dexterity in surgery, the dexterity index of surgeon operation space was proposed. Combined with the minimum gravity torque index and the redundancy index, this multi-objective optimization problem was solved by Salp Swarm optimization algorithm. Compared with the pre-optimization master manipulator, the performances of the optimized manipulator are overall improved by 10.3%, 23.0%, and 41.2% respectively in animal experiment.
