Background
Physics‐based vascular modelling is an essential issue to be addressed in the development of the endovascular interventional surgery training system, which helps to shorten the training period of novice surgeons to obtain dexterous skills of surgical operation.
Methods
A blood vessel model based on tensor‐mass method (TMM) is formulated and implemented in this context. A multimodel representation...
Mass Spring Model (MSM) and Finite Element Method (FEM) are two basic methods for soft model deformation simulation. However, MSM has a high computation efficiency but low accuracy which is only a coarse approximation of the real biological soft tissue while FEM is inverse on the two sides. To achieve realistic and real-time simulation at the same time, in this paper, we proposed an improved non-linear...
The development of robot technology provides a good opportunity for the development of robots in rehabilitation. As a result, robot for upper limbs has become more and more popular. Rehabilitation robot can use the related technologies to monitor and evaluate the rehabilitation process or the training condition, improve the training pertinence and science. Moreover, it can free physicians from heavy...
As an important branch of medical robot, rehabilitaction training robot for hemiplegic upper limbs is a hot research topic. Based on motor relearning program, it covers many technology fields, such as rehabilitation medicine, human anatomy, mechanics, computer science, and robotics, etc. With the developing of auxiliary robot, there are still some disadvantages in the existent devices, such as heavy...
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...
Neurological intervention surgery (NIS) is surgery branch vascular interventional surgery, one kind of the minimally invasive. And it has become the mainstream of the treatment in the cerebrovascular disease. Robotic surgery system with the functions of haptic feedback and the doctor-patient separation has enormous significance for the development of NIS. However, in previous studies, the haptic feedback...
The catheter-based operating system is a specific surgical technique that can reduce the pain of the patients and permit a faster recovery compared with the conventional open surgery. It has gained increasing acceptance by the clinicians and patients. This technology has gradually matured. And it has started to extend from the therapeutic areas of cardiovascular disease to the cerebral vascular disease...
The interventional surgery is a minimally invasive treatment, which uses the modern high technology. It takes the special catheter, guide wire and other precision instruments to import in the body to do the pathological diagnosis and local treatment under guide of medical imaging equipment. Interventional surgery has excellent characteristics like no operation, small trauma, rapid recovery, etc. It...
Tele-assessment systems are crucial for home-based rehabilitation, as they allow therapists to assess the status of patients and adjust the parameters of various home-based training devices. Traditional force/torque sensors are commonly used in tele-assessment systems to detect muscle strength because such sensors are convenient. However, muscle activity can be measured using surface electromyography...
Minimally invasive surgery (MIS) is a specialized surgical technique, the minimally invasive surgery compared to traditional surgery, not only can reduce the patient's pain, more can make the patients recover more quickly. But because the minimally invasive surgery is very complex, so the doctors need a lot of training to guarantee the realization of the surgery. In previous studies, we have developed...
Recognition for human elbow motion with surface electromyographic signal (sEMG) research receives more and more attention, especially in some fields like human machine interaction and measurement of human motor function due to the reason the EMG can reflect the activation of human muscle. However, continuous recognition for human elbow motion without load is still difficult due to the low signal noise...
Surface electromyography signal (sEMG) is deeply related with the activation of motor muscle and motion of human body, which can be used to estimate the intention of the human movement. So it is advantaged in the application of bilateral rehabilitation, where hemiplegic patients can perform rehabilitation training to their impaired limbs following the motion of intact limbs by using a certain training...
In this paper, we want to proposes an original study of the 3D vascular registration based on the multi-modality image fusion (such as CT and MRI fusion). First, we combine the basic clinical knowledge technology into the three-dimensional image reconstruction of real human vascular model for the purpose of the practical treatment measurement. Diagnosis and treatment of navigation technology should...
Minimally Invasive Surgery (MIS) is a specialized surgical technique that can reduce patients' pain and permit a faster recovery compared with conventional open surgery. But surgeons require extensive training to obtain the expertise due to its complexity. In the previous research, we have developed a virtual reality system to train surgeons to obtain the expertise to correctly perform the interventions...
As we know that MIS permits vascular interventions through very small incisions and minimizes the patients' trauma and permits a faster recovery compared. In this document, we present the mechanical and haptic simulation of the MIS VR operation training system. Virtual reality technology for doctors can improve the accuracy and safety of real vascular interventional surgery for vascular interventional...
There is an increasing realization that Minimally Invasive Surgery (MIS) is a specialized surgical technique that permits vascular interventions through very small incisions. Some operational tasks can be performed significantly better by robots than humans due to associated hazards and distance. However, the significant disadvantage of this surgical technique is its complexity; therefore, extensive...
The specialized surgical technique MIS that permits vascular interventions through very small incisions and minimizes the patients' trauma and permits a faster recovery compared to traditional surgery and it permits vascular interventions through very small incisions. In this paper, we present the mechanical analysis and haptic simulation of the catheter and vessel model for the MIS VR operation training...
Rehabilitation robotics has received more and more attention during the last decades, especially the exoskeleton device for the upper limb rehabilitation, but most of them are heavy and large. In our study, a light and wearable exoskeleton device was proposed, which can be used in home rehabilitation and it can also be used to implement passive and active training. In this paper, we proposed to perform...
Manual operation of steerable catheter is inaccurate in minimally invasive surgery, requires dexterous and efficient manipulation for the catheter and exposes the surgeons to intense radiation. A novel robotic catheter manipulating system has been developed to reduce the performance error and irradiation to surgeons. In addition, unlike the conventional technique which requires surgeons to manipulate...
