BackgroundRobots are gradually becoming intelligent tools for surgeons in computer assisted orthopedic surgery. A hands‐on robot combining CT‐free navigation software and coordinated control has been designed for total knee arthroplasty.
MethodsThe hands‐on robot is under bilateral force control so that the robot not only follows the force commands from the operator but also shapes the reflected force...
The performance of MIS is usually limited by restricted view field and awkward tool manipulation. An intelligent auto-tracking steerable endoscope has been proposed to solve the restricted view field issue. We design a flexible tip for an endoscope, which was actuated by cable-driven method. The flexible tip can rotate in all direction dynamically to keep the target within the view filed during the...
Robot assisted surgery can be safer than conventional counterpart. In total knee replacement, an intelligent tool with cooperative force control equipped by the proposed bone cutting through detection is advantageous to prevent from damaging surrounding soft tissue than by conventional method or computer navigation method. In this paper the developed auto-detection bone cutting through is able to...
In robot-assisted orthopedic surgery, an image-guided robot provides great assistance in accurate bone preparation by its rapid and accurate positioning capability. However, most of these robots are lack of tactile sensing or sufficient intelligence required for medical applications. It was found that the steering was not sufficiently taking into account of all possible situations and may damage the...
Wireless sensor networks (WSNs) have been widely used in many applications. Under outdoor surveillance, limited power supply to nodes in WSN systems is usually difficult to maintain operations for a long period of time. Previous studies have indicated that the load-balanced first layer nodes cannot extend the duration of WSN; more energy is consumed when nodes' loadings are heavy. The objective of...
The power of nodes in the first layer of a wireless sensor network (WSN) cannot last due to their frequent relay tasks. One possible solution to this disadvantage is to adopt the first order load-balanced algorithm (LBA) to redistribute the loading of the first layer node uniformly. The balanced low-latency convergecast tree (BLLCT) algorithm, a LBA, is generally utilized in route planning in ecological...
