Robot-assisted minimally invasive surgery becomes more and more popular, but the lack of force sensing for surgical robots restricts the development of this technology. The traditional way to obtain tool-tissue interaction force is to integrate sensors at the end of surgical instruments, which is not well adopted in practical due to high-cost and sterilization problems. It is necessary to explore...
The accuracy of registration is one of the key issues in surgical navigation, which directly affects the result of operation. In this paper, we proposed a new registration algorithm, Tetrahedral Framework (TF), to improve precision and computing speed and conducted a calibration experiment by using the wax model with markers. The image data are obtained by Micro-CT scanning and loaded in VTK to gain...
Robots play more important roles in daily life and bring us a lot of convenience. Somebody may need to cooperate with robots to complete some specific tasks. But when people work with robots, there remain some significant differences in human-human interactions and human-robot interaction. It is our goal to make robots look even more human-like. We hope that the robot can following the hand of human...
Laminectomy is a typical high-risk surgical operation on the spine, during which milling is the key procedure to remove part of vertebral lamina and release the pressure on the spinal nerve. Because many important vessels and nerves surround the vertebral lamina, any incorrect maneuver can cause irreparable damage to patients. In this paper, a fuzzy force control is designed specifically for vertebral...
During spinal surgery, spinal physiological motion (SPM) due to respiration can interfere with the operation. The patient is anesthetized and breathes passively with the aid of a respirator, causing periodic SPM. In this paper, a respiratory model based on the respirator flow waves is proposed; and a spinal physiological motion simulator (SPMS), which is based on a 3-RPS parallel mechanism, is developed...
Bone drilling is an important and difficult process in orthopedic surgeries. To detect the drilling state of a Robotic Orthopedic Surgery System (ROSS) in real-time, a state recognition method based on audio signals, the Acoustic Emission (AE) signals generated in drilling process, is proposed in this paper. By an analysis via power spectral density of the AE signals, an appropriate frequency band...
