Active medical devices that use thermal effects for cutting / coagulation are a hot research and development topic in this field. According to the principles of application, they can be divided into ultrasonic (such as ultrasonic scalpels, ultrasonic bone scalpels), microwave (such as microwave ablation needles), laser (such as semiconductor laser therapeutic devices), etc. However, according to relevant national standards and regulations, registration applications for such devices need to provide corresponding preclinical research data, which includes research on the dose-effect relationship of thermal damage to ex vivo tissues. However, there is currently no unified implementation standard and related auxiliary equipment for research on the dose-effect relationship of thermal damage to ex vivo tissues, and the operation is guided by experienced pathologists and laboratory experts in the laboratory.
[0003] During the experiment, the shape of the tissue after ex vivo separation is often irregular. After standard cutting, it will also be deformed due to the influence of gravity (such as liver, lungs, muscles, etc.). In addition, there is no corresponding ex vivo tissue fixation device, which makes the heating uneven during cutting or coagulation operations, and the cutting is easy to deviate from the cutting route, resulting in a large deviation in the thermal effect, which also makes it difficult to carry out subsequent pathological preparation effectively and accurately. Even if it is completed barely, the thermal damage results obtained are basically invalid.
