Description

Technical Field

[0001] This invention belongs to the field of microwave therapy control technology, specifically relating to a method for tracking and controlling the energy output of a microwave therapy device in a local area of ​​human tissue. Background Technology

[0002] Microwave therapy devices, as important equipment in modern physical therapy, generate a thermal effect by penetrating human tissue using 2450MHz microwaves, and are widely used in clinical scenarios such as inflammation treatment and tumor ablation. However, their energy output characteristics have an inherent contradiction: to achieve deep treatment (5-6cm penetration depth), higher power (1-99W) is required, but the absorption rate of microwaves by the human epidermis can vary by up to 30%, easily leading to local overheating and burns. Clinical data shows that in 2024, microwave therapy burn cases accounted for 17.3% of adverse event reports for medical devices in China, mainly due to the lack of a real-time energy regulation mechanism during treatment. This phenomenon is particularly prominent in heat-sensitive areas (such as the face and joints) and in patients with metal implants, seriously limiting the safe application range of the equipment. There is an urgent need to establish a method that breaks through the single-parameter control mode of traditional microwave therapy devices. Summary of the Invention

[0003] To address the problems of human error and unstable energy output in microwave therapy, this invention provides a method for tracking and controlling the energy output of a microwave therapy device in a local area of ​​human tissue.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The method of tracking and controlling the energy output of microwave therapy devices in local areas of human tissue is based on the upper limit of microwave radiation that the skin can receive in a certain area. Combined with the posture sensing of the handpiece, it is determined whether the handpiece is currently moving. Then, the microwave energy output power is adjusted so that when the handpiece is spinning in place or stops moving, the microwave energy output is reduced or stopped. When the handpiece is making linear displacement or circular motion trajectory that is not spinning in place, the microwave energy output is increased.

[0005] Furthermore, the tracking control method specifically includes the following steps: Step 1: First, the four corners of a unit area are marked on the skin surface using a hand tool, so that the skin area detection module can calculate the area of ​​the unit area and then calculate the maximum radiation energy of the unit area. Step 2: By setting the handpiece posture sensing module, the current usage posture of the handpiece is detected, and the microwave output power is controlled; when the handpiece stops moving, the microwave energy output is turned off; when the handpiece moves to a certain speed, the energy output is turned on, and the faster the handpiece moves, the greater the output power. Step 3: Combine the skin area detection module to determine whether the energy output of the current unit area exceeds the energy limit of that area; if the energy output of the unit area reaches the energy limit of that area, then stop the handpiece from outputting energy. Step 4: Repeat the above steps until the skin area to be treated is complete.

[0006] Furthermore, the handpiece is equipped with a temperature control module and a circulation system. The temperature is collected by a temperature sensor and fed back to the microwave therapy device. Combined with the circulation system, it can achieve the function of cold compress or hot compress.

[0007] Furthermore, the temperature control module includes an electronic fluorinated liquid, which, in conjunction with a circulation system, regulates the temperature of the contact surface between the handpiece and the human body by adjusting the temperature of the fluorinated liquid.

[0008] Furthermore, when the handpiece is stationary, with a displacement rate of <2 cm / s or spinning in place, the microwave output power is controlled to be 0. When the handpiece is making linear displacement or a circular motion trajectory that is not spinning in place, the output microwave power is automatically matched according to the movement speed of 2cm / s to 40cm / s.

[0009] Furthermore, the microwave output power is between 0 and 200W.

[0010] Furthermore, the skin region detection module reads the accelerometer and gyroscope sensor data from the inertial measurement unit (IMU) inside the handpiece, and calculates and derives the position and trajectory information of the handpiece to form the size of the skin detection area.

[0011] Furthermore, the hand gesture sensing module is located inside the hand and is powered by the main body of the microwave therapy device. By collecting data from accelerometer and gyroscope sensors, it calculates and derives the spatial gesture of the hand, including movement speed, rotation and displacement information.

[0012] Furthermore, the handpiece body is judged to be in contact with the skin by the change of the standing wave ratio of microwave radiation, and a standing wave detection device is installed inside the handpiece.

[0013] A tracking and control system for energy output in a local area of ​​human tissue using a microwave therapy device, specifically including a skin area detection module, a handpiece posture sensing module, an energy output control module, a main control module, a storage module, and a control panel module; The skin area detection module is used to determine the set unit area by the displacement of the handpiece, and then to determine the size of the skin detection area. The handpiece posture sensing module is used to determine whether the handpiece is in a moving state; The energy output control module is used to control the amount of energy output by the handpiece. The main control module is used to comprehensively regulate and coordinate the functions of each module. The storage module is used to store information, including detected skin area information, currently executing skin area information, output energy data, and hand gesture information. The control panel module is used for manually controlling the detection of the skin area and the output of energy.

[0014] Compared with the prior art, the present invention has the following advantages: The method of this invention can ensure that the microwave energy output in a specific area does not exceed the safety threshold that human tissue can withstand during microwave therapy. If it does, the microwave energy output will be shut off immediately. At the same time, it takes into account the problem that if the hand tool is accidentally left on the same skin surface for a long time during operation, it will cause excessive temperature rise of human tissue and thus cause skin damage.
