Problems solved by technology

[0003] In the prior art, when microwave radiators are used for ablation of thyroid tumors, only thyroid tumors with a diameter of more than 2 cm can be coagulated, and there is no good method for ablation of thyroid tumors with a diameter of less than 2 cm. When the radio frequency electrode and microwave radiator are solidified, when the diameter of the thermal field is 2 cm, the solidification area formed is oblong, and when the diameter of the thermal field is 4 cm, the solidification area formed is still spherical

Abstract

The invention discloses a cold tip temperature control fissure microwave ablation radiator, which comprises a stainless steel puncture needle, a polytetrafluoroethylene ring, a stainless steel shielding tube, a sealing ring, a closed piece, a hard coaxial cable, a cable connector and a microwave input seat. The front end of the stainless steel puncture needle is in a conical shape and the round bottom face of the rear end has a cylindrical boss; the stainless steel puncture needle is connected with the stainless steel shielding tube through the polytetrafluoroethylene ring; the hard coaxial cable is positioned in the stainless steel shielding tube and is connected with the microwave input seat through a cable connector; an annular inner cavity is formed between the stainless steel shielding tube and the hard coaxial cable; and the sealing ring is positioned in the annular inner cavity of the end port, which is close to the polytetrafluoroethylene ring, of the stainless steel shielding tube; and the closed piece is positioned in the annular inner cavity of the other port of the stainless steel shielding tube. The cold tip temperature control fissure microwave ablation radiator can directly puncture thyroid tumor which is less than 2 centimeters and form a spherical condensing area, thereby radically ablating the thyroid tumor.

Description

technical field [0001] The invention relates to a microwave surgical treatment instrument, in particular to a radiator of the microwave surgical therapeutic instrument. Background technique [0002] Microwave therapy has been used internationally and in China for many years, and its curative effect has been affirmed by the world's medical circles. With its superior hemostatic effect, advanced action principle, and minimal tissue damage during surgery, it has been hailed as a new technology to replace electrocautery, freezing, and laser. [0003] In the prior art, when microwave radiators are used for ablation of thyroid tumors, only thyroid tumors with a diameter of more than 2 cm can be coagulated, and there is no good method for ablation of thyroid tumors with a diameter of less than 2 cm. When the radio frequency electrode and microwave radiator are solidified, when the thermal field diameter is 2 cm, the solidification zone formed is oblong, and when the thermal field d...
