Minimally invasive interventional surgery shows its advantages compared to traditional operation. The master-slave robotic system technology can further significantly improve the accuracy, efficiency and safety of this complicated and high risk operation. However, one of the critical issues in the robotic system, guide wire force feed-back, needs more research. The mechanical structure of the salve robot is designed basing on modularizing design principle. Ball spline pair, guide pair and herringbone gear pair are adopted in the structure concept. The experimental equipment is developed and the verifying experiments are conducted. The guide wire detected feedback force matches well with the detected resistance force. It indicates that the designed slave part and design method is rational from the point of feedback force detection.

The interventional surgery is a type of minimally invasive operation which can reduce hospitalization time and greatly decrease patient morbidity compared to traditional methods. In our previous study, a master-slave interventional operation system has been developed. The master side was a Phantom device and the PID control was used through upper machine. To further improve the precision and synchronization performance, two laser range finders were applied to measure the position of the master side in this paper. And positioning compensation on the basis of force feedback was added to the position close-loop. Compared to the previous result, the new method had advantages on precision and accuracy.

With the development of various imaging technologies, medical imaging has been playing more important roles on providing scientific proof for doctors to make decisions on clinical diagnosis. At the same time, it is very important to excavate valuable information hidden in those images and take over some auxiliary medical works from doctors by the computer. Therefore, a large number of image segmentation methods, including some classic algorithms have been proposed and some of them perform well. In this paper, we built a deep convolutional neural network to segment the MRI brain images. Results show that the network has a good performance on segmentation of the gray and white matter of brains, it also had a good generalization ability.

Minimally invasive surgery is a specialized surgical technique that permits vascular interventions through very small incisions. It minimizes the patient's trauma and permits a faster recovery compared to traditional surgery. Although traditional invasive surgery training system can complete general training work, real-time performance and accuracy of most training system failed to meet the requirements of training work. Therefore, in this study, three parts, including 3D modeling, collision detection algorithm and application architecture were improved in the existing training system. Firstly, an improved Marching cubes algorithm was adopted to simplify the mathematical modeling of vessels by merging the related points of the mesh model. Secondly, a hybrid collision detection algorithm was proposed and implemented. Lastly, the CPU-GPU parallel computing architecture was adopted. Particularly, the design of the improved VR-based system and the experimental results were presented and analyzed. Moreover, experimental results showed that the proposed system was beneficial to improve the skill of surgeons in manipulating the catheter and guide wire. Thus, the simulators could be used for trial surgery training. © 2016 IEEE.

The aim of the present study is to examine the function of indices of macrostructural sleep and microstructural sleep for the objective evaluation of sleep quality, to test and find out the indices which could distinguish normal sleep from four types of pathologic sleep, including insomnia, nocturnal frontal lobe epilepsy (NFLE), periodic leg movements and rapid eye movement (REM) behavior disorder. The role of sleep indices for the evaluation of sleep quality was analyzed, including 29 macrostructure indices and 23 microstructure indices. Totally five sleep groups were selected from the cyclic alternating pattern (CAP) sleep database, including controls (no pathology, N=16), insomniacs (N=9), nocturnal epileptics (N=40), periodic leg movements (N=10) and REM behavior disorder (N=22). The macrostructure indices were calculated according to the sleep stages annotation in the database, and the microstructure sleep indices were obtained by analyzing the CAP annotation. The discrimination ability of these macrostructure and microstructure indices was tested by analysis of variance for distinguishing the normal sleep from four types of pathologic sleep. For macrostructure sleep indices, four REM-related indices of controls were distinguished from that of pathologic groups significantly (P<0.05, controls vs. each pathologic group), including the time of REM sleep, the percent of REM sleep to all sleep period time, the ratio of REM sleep to non-rapid eye movement (NREM) sleep, and the maximal sustained REM sleep time. For microstructure sleep indices, three phase A3-related indices of controls were significantly distinguished from that of pathologic groups (P<0.05, controls vs. each pathologic group), including the number of phase A3 per hour during NREM sleep, the total number of phase A3, and the total duration of phase A3. In conclusion, REM sleep indices can distinguish normal sleep from four types of pathologic sleep, including insomnia, nocturnal epilepsy, periodic l

During cardiovascular and cerebrovascular interventional surgical procedure, the accuracy of guide wire advance is particularly important for the success rate and safety of surgery, a single PID controller can't adapt to the complex surgical situations, the performance of the system has much room for improvement. In this paper, a fuzzy PID control algorithm with guide wire feedback force was proposed. According to the various situations in surgical procedures, multiple PID controller were designed correspondingly. In the actual surgical procedure, according to the different feedback-force of guide wire, the controller switches between different sets of PID controllers in real time to achieve more excellent performance respectively under different circumstances. Experimental results show that the fuzzy PID controller with guide wire feedback force achieves more excellent performance than the classical PID controller. And the dynamic performance of master-slave control system is better, the following error is reduced, overshoot decreases, and surgical safety greatly increased.

Information exchanges and cooperative movements of multiple robots have become a hot topic in robotics. To increase the adaptability of robots in amphibious scenarios, an improved amphibious spherical robot was designed in this paper. However, the ability of single robot was limited. To further increase the sensing range and work efficiency of own amphibious spherical robots, a Leader-follower method, which could realize the coordinated movement and formation keeping for three or more robots, was adopted in this paper. The theoretical analysis show that the Leader-follower method could be easily applied in amphibious spherical robots for practical applications. And a simulation experiment platform named Player/Stage was used for verifying the effectiveness of this method. The construction of the experimental environment and the final simulation results were provided in this paper. Through the analysis of experimental results, the feasibility of the Leader-follower method was verified, and this method will be used to implement multiple amphibious spherical robots cooperative motion in future works.

Developing efficient movement gaits for quadruped robots has intrigued investigators for years. Trot gait, pace gait, as fast and stable dynamic locomotion gaits, have been widely used in robot control. Therefore, the purpose of this paper is to control an amphibious spherical quadruped robot to achieve these two gaits. Firstly, this paper references the trot gait and pace gait pattern of quadruped creature and identifies the order and the law of quadruped bionic robot. Secondly, based on the virtual leg techniques and the Spring-Loaded Inverted Pendulum (SLIP) model, a simplified dynamic analysis model is established, and the relationship between force and motion is obtained by using Lagrange dynamics equation. Thirdly, by adjusting the force and moment of the joint of robot, continuous and stable trot gait and pace gait motion are simulated in ADAMS platform. Finally, a comparison of theoretical calculations and simulation results demonstrated the robot's potential and its feasibility of trot gait and pace gait.

A microfluidic cytometer with integrated on-chip optical systems was designed for red blood cell (RBC) and platelet (PLT) counting. The design, fabrication, and characterization of the microfluidic cytometer with on-chip optical signal detection were described. With process using only a single mask, the device that integrates optical fibers and on-chip microlens with microfluidic channels on a polydimethylsiloxane layer by standard soft photolithography. This compact structure increased the sensitivity of the device and eliminated time-consuming free-space optical alignments. The microfluidic cytometer was used to count red blood cells and platelets. Forward scatter and extinction were collected simultaneously for each cell. Experimental results indicated that the microfluidic cytometer exhibited comparable performance with a conventional cytometer and demonstrated superior capacity to detect on-chip optical signals in a highly compact, simple, truly portable, and low-cost format that is well suitable for point-of-care clinical diagnostics.
