The neural stimulator is a core component of animal robots. While the control effect of animal robots is influenced by various factors, the performance of the neural stimulator plays a decisive role in regulating animal robots. In order to optimize animal robots, embedded neural stimulators had been developed using flexible printed circuit board technology. This innovation not only enabled the stimulator to generate parameter-adjustable biphasic current pulses through control signals, but also optimized its carrying mode, material, and size, overcoming the disadvantages of traditional backpack or head-inserted stimulators, which have poor concealment and are prone to infection. Static, in vitro, and in vivo performance tests of the stimulator demonstrated that it not only had precise pulse waveform output capability, but also was lightweight and small in size. It had excellent in vivo performance in both laboratory and outdoor environments. Our study has high practical significance for the application of animal robots.

With the progress of science and technology and the increase of clinical demand, medical robots have developed rapidly and played a important role in promoting the medical cause. Service robot is a branch of medical robot, which is mainly oriented to medical service and assistance needs, and has been applied in many medical scenarios and achieved demonstration effects. This research first describes the development of medical service robots, and then summarizes the key technologies and clinical applications of robots. Finally, it points out the challenges and directions that medical service robots face at present, and puts forward prospects for their further development in the medical field.

During the last decade, robotic surgery for rectal cancer has rapidly gained acceptance among colorectal surgeons worldwide, with well-established safety and feasibility. The lower conversion rate and better surgical specimen quality of robotic compared with laparoscopic surgery potentially improves survival. Earlier recovery of voiding and sexual function after robotic total mesorectal excision is another favorable outcome. Long-term survival data are sparse with no evidence that robotic surgery offers major benefits in oncological outcomes. Although initial reports are promising, more rigorous scientific evaluation in multicenter, randomized clinical trials should be performed to definitely determine the advantages of robotic rectal cancer surgery.

Intelligent and precision medical treatment is the future development trend of surgical operations. We proposed a core architecture of orthopedic robots with human-like thinking based on the growing demand for orthopedic robots and disadvantages of current robots, it consists of brain, eyes and hands three modules according to functions. The architecture design is extremely in line with the doctor's logic so that the work process of the orthopedic robot is similar to the process of traditional surgery which is mainly done by the doctor's brain-eye-hand coordination. It realizes the digitization of the doctor's thinking, the immediacy and visualization of surgical information and the accuracy of surgical operation process. The clinical application proved that the orthopedic robot has the advantages of higher accuracy, less radiation and shorter operation time, which can be further promoted clinically.

Robotically assisted microsurgery or telemicrosurgery is a new technique using robotic telemanipulators. This allows for the addition of optical magnification (which defines conventional microsurgery) to robotic instrument arms to allow the microsurgeon to perform complex microsurgical procedures. There are several possible applications for this platform in various microsurgical disciplines. Since 2009, basic skills training courses have been organized by the Robotic Assisted Microsurgical and Endoscopic Society. These basic courses are performed on training models in five levels of increasing complexity. This paper reviews the current state of the art in robotically asisted microsurgical training.

PURPOSE: The purpose of this study was to identify the effects on cognitive function, mood, problematic behaviors and response to interaction with robot pet by elderly people with dementia. METHOD: A methodological triangulation design with quantitative and qualitative methods was used. The participants were 9 elderly people with dementia. The intervention was conducted twice a week for 4 weeks. Qualitative data were collected by interviews and video-taping for analysis of the responses of participants. RESULTS: 1) Cognitive function, mood and problematic behaviors did not show any significantly differences after the program. 2) Analysis of the responses showed increases in verbal communication and positive action. CONCLUSION: The robot pet program had positive effects such as increasing communication and interaction. Therefore, this program could be considered as an effective program for emotional support for elderly people with dementia. However further repetitive study is need to validate the result

Aggressive angiomyxoma (AA) is a very rare mesenchymal tumor most commonly found in the pelvic and perineal regions. For the complete excision of retrorectal tumors, with extension through the levator muscle into the ischioanal space, open anterior and posterior approaches are typically required. Herein, we report our experience with robotic excision of a giant presacral AA with extralevator extension into the ischioanal space and extraction via Pfannenstiel incision, which we found to be technically feasible, efficacious, and safe to perform. Mayo Clinic Institutional Review Board exemption status was obtained for this study.

A motion unit for sucking robot with a stable motion, convenient operation and process simulation is introduced. The key parameters and process data of the sucking operation were obtained from the clinical work, which provided the basis for the design of the sucking robot motion unit. According to the points of sucking action, robotic thumb, forefinger and metacarpophalangeal joints were used to grip the suction tube, and the servo and arm structure were used to simulate the motion of the wrist and elbow to complete the rotation and push of the sputum suction tube. The feasibility is verified through the advanced sputum suction training model. The movement unit is stable in movement, and can smoothly complete the clamping, feeding, back off protection and rotating tube removal of the sputum suction tube, so as to achieve effective sputum suction.
