A review of the research progress of interventional medical equipment and methods for prostate cancer

Abstract

Background: Prostate cancer is a common disease in men and has a relatively high mortality rate. However, the interventional medical equipment used for prostate biopsy and brachytherapy has always been a social concern.Methods: To understand interventional medical equipment for prostate cancer, the structure of manual, semi-automatic and automatic medical equipment were considered as the mainline, while the corresponding research on these structures were the auxiliary lines. The characteristics and corresponding research status have been discussed.Results: Interventional medical equipment for prostate cancer with different degrees of automation and its characteristics were determined, and the imaging principles and characteristics of computed tomography, transrectal ultrasound and magnetic resonance imaging have been briefly described. Conclusion:Certain feasible research suggestions have been proposed for future development from the perspective of structure, accuracy and safety. These include flexible and compact robot structures, high-precision image recognition and guidance, accurate dose planning and monitoring, real-time imaging monitoring without delay, high-precision needle insertion strategy, master-slave control, virtual reality and remote control.

2-DOF MIMO decoupling control of the gantry high performance motion system

“…It can be seen from formula (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) that if the tracking error e is reduced to zero, F = G , the design principle of the feedforward controller F is to approximate the inverse of the controlled object model as much as possible.…”

“…The gantry high performance motion system is widely applied in semiconductor equipment [1], CNC machine [2], laser cutting machine [3], medical equipment [4], etc. Its advantages are large stroke, large driving force, high load and high bandwidth.…”

Structural design and analysis of pneumatic prostate seed implantation robot applied in magnetic resonance imaging environment

“…With the rapid development of the robotics industry in recent years, more and more robotic technologies have been applied to clinical operations and are gradually accepted by patients and doctors 11 . The combination of robotic technology and radiotherapy technology can overcome the shortcomings of traditional radiotherapy used by doctors; if doctors directly operate large‐scale surgical instruments, long‐term surgery is likely to cause fatigue, quality degradation, and can not give full play to the doctor's surgical level, and Surgical operations are complex, and young doctors need to go through long‐term study and professional training 12 .…”

“…9,10 With the rapid development of the robotics industry in recent years, more and more robotic technologies have been applied to clinical operations and are gradually accepted by patients and doctors. 11 The combination of robotic technology and radiotherapy technology can overcome the shortcomings of traditional radiotherapy used by doctors; if doctors directly operate large-scale surgical instruments, long-term surgery is likely to cause fatigue, quality degradation, and can not give full play to the doctor's surgical level, and Surgical operations are complex, and young doctors need to go through long-term study and professional training. 12 So, minimally invasive interventional surgery robot technology, as the most promising key technology in the field of medical robots in the future (represented by the DaVinci robot developed by American Intuitive Corporation), not only has high positioning accuracy, good motion stability, but also can replace Physicians work continuously while causing less trauma to patients and facilitating postoperative recovery.…”
