Seven key technologies in the medical robot industry

In the “2016-2020 China Medical Robot (300024) Industry In-depth Research and Investment Prospect Forecast Report”, CIC Consultant stated that the key technologies of the medical robot industry are as follows:

First, optimize design technology

Since medical robots are called robots, they cannot be separated from the basic theories and key technologies of robots, including mechanism, control, sensing, human-computer interaction, teleoperation and materials. This is not much different from traditional robots. When designing, we must get rid of the "shadow" of traditional industrial robots, and realize the innovative design of lightweight, precise and smart robotic mechanism.

Second, system integration technology

Medical robots have the special connotation of "medical" and require safety and effectiveness. System integration must be directed to the specific surgical process needs, consider how the operating room is applied, pay attention to the study of human-computer ergonomics. If the doctor does not accept your system, your theoretical work is done well, and the technology is advanced and it is impossible to promote it. Therefore, medical robots emphasize the communion of "doctor-robot-patient".

Third, remote surgery technology

Most of the successful surgical robots are master-slave operating robots. The future trend is remote surgery. Therefore, remote control and remote surgery techniques are also valued.

Fourth, surgical navigation technology

Based on the 3D surgical planning of the robot system, the real-time calibration and registration of the intraoperative real-time calibration and registration are realized by using the real-time reconstruction and fusion processing of medical images and the high-precision 3D tracking and visualization technology of the surgical robot.

Fifth, software robot technology

Software robot technology is a popular technology nowadays, and the future prospects in the medical field are also very good. For example, ureteroscope robots are very promising in urology.

Six, assisted interventional therapy

Since the 1990s, interventional therapy has developed rapidly. Under the guidance of medical imaging (such as CT, MRI, US, X-ray, etc.), this technology introduces special precision instruments such as catheters and guide wires into the human body. Diagnosis and topical treatment. This technology has opened up new effective treatments for many diseases that have been clinically considered to be incurable or refractory. Interventional doctors place catheters or other instruments into almost all of the body's vascular branches and other luminal structures (digestive tract, biliary tract, trachea, nasal cavity, etc.) and certain specific sites to limit the treatment of many diseases. It is also especially suitable for liver, lung, stomach, kidney, pelvic, bone and soft tissue malignancies that have lost or are not suitable for surgery.

Interventional therapy has the characteristics of no surgery, less trauma, quick recovery, good curative effect and low cost. Some scholars will even be involved in the three major medical treatment techniques in parallel with internal medicine and surgery.

At present, there are certain problems in interventional therapy. For example, most interventional treatments are performed in traditional two-dimensional images, which results in inaccurate positioning of the target of the lesion and affects the effect of interventional therapy; the doctor is exposed to X for a long time. Radiation, CT and other radioactive radiation damage the health of doctors; because there is no positioning of surgical instruments, doctors can not accurately place surgical instruments into the target of the lesion at one time, and need to gradually insert the target under the guidance of the image. Points, reducing the efficiency of surgery; due to the limitations of hand movement and accurate grasp of surgical tools for a long time will make the doctor feel very tired, and due to fatigue and unstable hands and other factors will affect the quality of surgery; High, only experienced doctors can carry out, not easy to be mastered by general doctors, limiting the wide application of this technology.

The key to interventional therapy is to accurately place the precise surgical instruments into the target of the lesion to achieve the purpose of treatment. This requires solving the problems of scientific design before treatment, accurate positioning in treatment, stable puncture and instrument support. The robotic assisted system is an important way to solve the above-mentioned traditional interventional treatment problems. The robot assisted system uses computer technology to analyze medical image information, and uses medical robots to achieve precise positioning and auxiliary operations based on the construction of three-dimensional space coordinates. Therefore, the intervention technology is combined with the advantages of accurate positioning, stable state, strong dexterity, large working range and standardized operation process, which reduces the human factors in the treatment, makes the interventional treatment more precise, dexterous and safe, and overcomes the complete dependence. Doctor's experience.

Seven, medical and Internet big data

Due to the emergence of new technologies, medical robots also need to keep pace with the times, including digital medical, mobile medical, wearable medical and telemedicine. This trend is becoming more and more obvious. Japan's Pepper robots can use cloud computing and big data to get involved in emotional support, which is also a future development trend.
