FAQ
Minimally invasive surgical instruments achieve precise cutting and hemostasis through a variety of technologies. Among them, ultrasonic scalpel is a common tool. Its working principle is to use the electrostrictive effect or magnetostrictive effect to convert electrical energy into mechanical energy through the transducer, and the kinetic energy on the handle is amplified to cut tissue. When the blade contacts the tissue, the high-frequency vibration generated will instantly form a high temperature on the contact surface, causing the protein between cells to instantly denature and coagulate, achieving the cutting effect while achieving minimally invasive hemostasis.
In addition, the arthroscopic planer uses the high-speed airflow generated by the rotation of the turbine to drive the planer to rotate rapidly, similar to the principle of an electric toothbrush, with high hardness and wear resistance, suitable for precise cutting. Robot-assisted surgical instruments can also provide highly precise surgical operation capabilities, which is conducive to doctors to perform precise cutting and suturing.
These minimally invasive surgical instruments achieve precise cutting and hemostasis of soft tissues during surgery through different technologies and principles, reducing surgical damage and bleeding.
The working principle of ultrasonic scalpels in minimally invasive surgical instruments is mainly to use the electrostrictive effect or magnetostrictive effect. Specifically, the host outputs electrical signals, which are transmitted through the transducer handle, and the electrostrictive effect or magnetostrictive effect is used to convert electrical energy into mechanical energy. This mechanical energy generates high-frequency vibrations, which drive the blade to work through the amplification and coupling of the amplitude transformer, and radiate energy to local tissues of the human body, thereby performing surgical treatment.
The turbine rotation technology of the arthroscopic planer achieves high-speed airflow drive through low-inertia double-fan turbine power technology. This technology uses the high-speed rotation of the turbine to generate a strong airflow, thereby achieving soft tissue ablation (vaporization), repair, cutting and vascular hemostasis during surgery.
Regarding its specific impact on tissue damage, although there is no detailed description in the information I searched, it can be inferred that since the turbine rotation technology can generate high-speed airflow, it may cause certain thermal damage or mechanical damage to the surrounding tissues. However, modern medical devices are usually equipped with technologies such as automatic boost delay/sleep start monitoring to ensure that tissue damage is minimized during surgery.
The technical principles of robot-assisted surgical instruments in precise cutting and suturing mainly rely on high-precision positioning technology and image recognition technology.
First, the surgical robot can intelligently plan the path of cutting and implantation by obtaining the reference position of the lesion. This positioning technology can be divided into different principles such as mechanical and ultrasonic types to ensure the standardization of surgery and reduce unnecessary X-ray radiation during surgery.
Secondly, surgical instruments can achieve actions such as clamping, rotation, cutting and suturing during operation. The precise execution of these actions depends on the high-precision mechanical structure and control system of the robot system.
In addition, image recognition technology for surgical instruments and tissues also plays an important role. By identifying the color, geometric features, texture features or additional attached markers of instruments and tissues in the surgical field of view, doctors can better perceive the surgical environment, thereby improving the accuracy of surgery.
There are multiple studies and case studies evaluating the effectiveness of minimally invasive surgical instruments in reducing bleeding. Here are some specific studies and cases:
Application case of Zhujiang Hospital of Southern Medical University: Using robot-assisted laparoscopic minimally invasive surgery solutions, the results showed that the intraoperative bleeding of patients undergoing radical prostatectomy decreased by 17%.
Clinical application study of Minilap-assisted transumbilical single-port laparoscopic cholecystectomy: The study showed that the average operation time and intraoperative bleeding in the observation group were significantly reduced (29.90 minutes and 4.90mL, respectively, and 19.10 minutes and 8.05mL, respectively, in the control group, P=0.000).
Product concept and technology development trend of Sinomicro: The biggest advantage of ultrasonic scalpel is that it can cut and coagulate at the same time, which greatly reduces the amount of bleeding.
Minimally invasive surgical instruments and traditional surgical methods have their own advantages and disadvantages in terms of postoperative recovery and patient satisfaction.
Advantages:
Fast postoperative recovery: Minimally invasive surgery has less trauma and less bleeding, which greatly reduces damage to organs and interference with organ functions, shortening postoperative recovery time. In addition, minimally invasive surgery has small incisions, low pain, low risk of infection, and shorter hospitalization and recovery time. For example, laparoscopic surgery is performed through a small incision, with mild postoperative pain and rapid recovery.
Reduce complications: Traditional surgery has long incisions, which are prone to problems such as incision dehiscence, incision hernia, and incision infection, while minimally invasive surgery can effectively reduce the occurrence of these complications.
Less trauma: Minimally invasive surgery uses several small incisions and is performed through a television monitor. Compared with the large incisions of traditional surgical operations, the trauma is significantly reduced.
Less bleeding: Minimally invasive surgery is characterized by less trauma and less bleeding, which helps to recover faster after surgery.
Disadvantages:
Poor operability: Existing handheld minimally invasive surgical instruments have defects such as poor operability and lack of dexterity, making it difficult to perform surgical operations freely and accurately.
High price: Although surgical robots are easy to operate, precise and dexterous, their high price may limit their widespread application.
Limited scope of application: Not all types of surgery are suitable for minimally invasive methods. For example, some intestinal cancers may not be easy to operate under minimally invasive methods, or they may not be cleanly cut under minimally invasive methods. In this case, traditional surgery may be a better choice.
