Electric heating scalpel for tumor thermotherapy and preparation method of electric heating scalpel

Abstract

The present invention provides an electric heating scalpel for tumor thermotherapy. The electric heating scalpel for the tumor thermotherapy comprises a scalpel head part, a scalpel body part and a handle part which are connected together, the scalpel body part is positioned between the scalpel head part and the handle part, the scalpel head part comprises a scalpel head and a connecting column, and the scalpel head and the connecting column are integrally arranged; the scalpel body part comprises a metal tube, a metal ceramic composite heating core is arranged in the metal tube, and the metalceramic composite heating core is connected with the scalpel head; the handle part comprises a metal connecting sleeve, the metal tube is arranged at the metal connecting sleeve, the metal connectingsleeve is sleeved with a handle sleeve, and one end, far away from the scalpel body, of the metal connecting sleeve is provided with a plug; and the plug is connected with the metal ceramic compositeheating core. The electric heating scalpel achieves accurate control of heating temperatures through the metal ceramic composite heating core and can achieve a good treatment effect.

Description

technical field [0001] The invention relates to an electrothermal scalpel for tumor thermotherapy and a preparation method thereof. Background technique [0002] Tumor thermotherapy is a treatment technique that uses heat energy to kill cancer cells. Modern medical research shows that normal human tissue cells can still survive at 48°C, but cancer cells will die when heated to 43°C. Therefore, heating tumor tissue above 43°C to selectively kill cancer cells is considered to be an effective tumor treatment method. Based on this principle, people use hot water, far-infrared, microwave, ultrasonic, etc. to generate thermal energy to treat tumors, but these methods are either difficult to accurately control the temperature, or cannot effectively place the heat on the diseased tissue, or are inconvenient to operate, and it is difficult to achieve the desired effect. treatment effect. Therefore, people directly contact cancerous cells with a kind of electric knife, directly kil...

AI Technical Summary

Problems solved by technology

However, the conventional electric heating knife cannot accurately control the temperature of the knife head. When the temperature is not enough, the diseased cells cannot be effectively killed, and the treatment effect is not good. When the temperature is too high, it will damage normal tissue cells and increase the pain of the patient.
