Embodiment 1

[0024] Such as Figure 1-Figure 4 As shown, this embodiment has a semi-rigid water-cooled microwave ablation antenna that integrates real-time temperature measurement and ablation, and its composition includes: a radiation head 1, a dielectric tube 2, a semi-rigid coaxial cable 3, a fastening ring 4, and an outer guide sleeve 5 , Water cavity cover 6, water inlet pipe 7, water outlet pipe 8, centering collar 9, thermoplastic pipe 10, outer sheath pipe 11, T-shaped positioning piece 12, disc-shaped bracket 13, radio frequency pin connector 14 , Handle tail 15, spout 16, water inlet 17, Huff handle body 18, handle end 19, pure copper wire temperature measurement wire 20, copper-nickel alloy wire temperature measurement wire 21 and temperature measurement special transfer terminal 22.

[0025] Such as figure 1 As shown, in the two axial oblique holes of the conical and large cylindrical body at the front of the radiation head 1, a pure copper wire temperature measuring wire 20 a...

Embodiment 2

[0042] The difference between the antenna of this embodiment and the first embodiment is that it adopts an L-shaped gun handle with a better hand feeling, and the difference in its internal structure is that the two dedicated transfer terminals 22 for temperature measurement are fixed on the (L-shaped) bracket 13 ,Such as Figure 6 shown. Figure 6 The middle marks indicate that reference may be made to Example 1.

Abstract

A semi-rigid water-cooled microwave ablation antenna with real-time temperature measurement and ablation, including: radiation head, dielectric tube, semi-rigid coaxial cable, and the "water heat exchange chamber" composed of the outer guide sleeve and the water chamber sleeve and the inlet and outlet The waterway cooling system in the antenna body composed of capillary water tubes is characterized in that it also includes a temperature measuring device with a T-type thermocouple in the radiation head, and its temperature measurement end protrudes from the top of the radiation head, which can interact with microwaves. There is no gap contact, the method is reliable, the structure is stable, and the linearity is good and the sensitivity is high. The reliable and effective temperature measurement method of the present invention breaks through and solves the problem that the semi-rigid microwave ablation antenna performs real-time temperature measurement while performing microwave hyperthermia or microwave ablation in the cavity, intestinal tract or blood vessel, or even the heart. It provides a strong guarantee for obtaining the best curative effect and its application expansion, and also creates favorable conditions for the intelligentization of semi-rigid microwave hyperthermia or microwave ablation.

Description

technical field [0001] The invention relates to a semi-rigid water-cooled microwave ablation medical device with integrated real-time temperature measurement and ablation, belonging to the application field of medical microwave technology. Background technique [0002] With the rapid development of modern high-tech and bioengineering, since the 21st century, medical microwave technology has been more widely used for microwave hyperthermia on the body surface or outside the body, microwave hyperthermia or microwave ablation and Intervening in the three major branches of microwave ablation of tumors in organs, tissues or bones, it is highly valued and welcomed by doctors and patients. [0003] The rapid expansion of the application of medical microwave technology is based on the thermal and non-thermal effects of microwaves acting on organisms and the mechanism of microwave thermal effects. Human cells are exceptionally heat sensitive. In clinical microwave therapy, when the...
