Cervical microwave thermotherapy radiator

Abstract

The invention discloses a cervical microwave thermotherapy radiator, comprising a positioning air bag, an inflating catheter, an inflating joint, a radiator antenna, a microwave radiator, an outer catheter, an inner catheter, a microwave cable, a front-end sealing ring, a rear-end sealing ring, a cable joint and a microwave input seat, wherein one end of the microwave cable is connected with the microwave input seat by the cable joint, and the other end of the microwave cable penetrates into the inner catheter and extends into the microwave radiator to be connected with the radiator antenna; the outer catheter is sheathed outside the inner catheter; the microwave radiator is fixedly connected to the front ends of the outer catheter and the inner catheter; the front-end sealing ring is positioned between the inner catheter and the microwave cable, and the rear-end sealing ring is positioned between the rear end of the outer catheter and the rear end of the inner catheter; and the positioning air bag is fixedly connected onto the microwave radiator, and one end of the inflating catheter is connected with the inflating joint, and the other end of the inflating catheter penetrates through a ring-shaped inner cavity between the outer catheter and the inner catheter and the microwave radiator and extends into the positioning air bag. The cervical microwave thermotherapy radiator disclosed by the invention has the advantages that the accuracy of radioactive thermotherapy is ensured, and not only can the human tissue be prevented from being burnt, but also the lesion tissue can be killed so as not to be easy to recur after a patient is healed.

Description

technical field [0001] The invention relates to a microwave surgical treatment instrument, in particular to a radiator of the microwave surgical treatment instrument. Background technique [0002] Microwave therapy has been used internationally and in China for many years, and its efficacy has been affirmed by the world's medical community. During surgery, it has been hailed as a new technology to replace electrocautery, freezing, and laser due to its superior hemostatic effect, advanced mechanism of action, and minimal tissue damage. [0003] In the prior art, the use of microwaves to treat cervical disease has been widely used in clinical practice. The main factor of microwave treatment of cervix is ​​thermal effect. , the dipole rotates, consumes energy and generates heat in order to overcome the viscosity of the medium in which it is located, and through control, the microwave enters the diseased tissue according to clinical needs, and the high heat denatures and coagul...

AI Technical Summary

Problems solved by technology

[0005] 1) Without temperature control measures, human tissues are often burned during the treatment process;

[0006] 2) Due to the lack of positioning devices, the diseased tissue cannot be completely inactivated, so that the microwave treatment is not complete, and it is easy to relapse after curing
