Medical microwave treatment equipment and control method thereof

Abstract

The invention discloses medical microwave treatment equipment and a control method thereof. A microwave oscillator, a filtering and driving module and a radio frequency isolation and final amplification module are connected in sequence, and microwave power is output to an application component. The parameter acquisition and embedded control module acquires current and temperature real-time values of the power final-stage amplifier and forward and reverse power of the output end of the radio frequency isolator, and adjusts and controls power output. A cooling system in the main control and auxiliary function module is controlled by the main controller to realize internal cooling of an application part through a cooling liquid circulation loop; under the control of the main controller, the internal temperature of the application part is sampled through the temperature acquisition system, and the power output of the whole system can be cut off through the embedded controller. The man-machine interaction module is connected with the main controller, and the real-time working condition of the system is obtained through the man-machine interaction module. The output power of the solid-state microwave source can be corrected based on working current, forward and reverse power and temperature change control, and safety and reliability of equipment are guaranteed.

Description

technical field [0001] The invention relates to a signal generating device for minimally invasive treatment equipment, in particular to a medical microwave treatment equipment and a method for controlling microwave power output. Background technique [0002] Microwave technology has been used for decades in surgical coagulation, tissue dissection, and ablation of liver and thyroid tumors / nodules. Compared with traditional surgery, it can significantly reduce the amount of surgical blood loss and improve the success rate of surgery. In the field of treatment of liver and thyroid nodules, its effect is even comparable to surgical resection, with less surgical trauma and faster postoperative recovery. , liver function / thyroid function can be preserved to the greatest extent and other advantages, so it is more and more popular in interventional (ultrasound) department, endocrinology department, oncology department, surgery and other departments. [0003] There are one or more...

AI Technical Summary

Problems solved by technology

[0006] 1. Temperature changes will lead to deviations in the output power of solid-state source microwave therapeutic instruments. This patent does not address the impact of temperature changes on the accuracy of solid-state source output power

[0007] 2. Working parameters in the solid-state microwave source, such as forward and reverse power, standing wave ratio, working current, etc., will change in real time. This patent fails to monitor its working status in real time, and it is difficult to guarantee the safety of microwave therapy operations
