Example Embodiment

[0023] Embodiment one

[0024] like 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] like 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 ...

Example Embodiment

[0041] Embodiment two

[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 ,like Image 6 shown. Image 6 The middle marks indicate that reference may be made to Example 1.

Abstract

A real-time temperature measuring and ablation integrated semi-rigid water cooling microwave ablation antenna comprises a radiation head, a medium tube, a semi-rigid coaxial cable, a 'water heat exchange cavity' composed of an outer guide sleeve and a water cavity sleeve and a water channel cooling system which is composed of inlet and outlet capillary water tubes and arranged in an antenna body. The antenna is characterized by further comprising a temperature measuring unit provided with a T-shaped thermocouple. A temperature measuring end of the temperature measuring unit protrudes from the top end of the radiation end and can be in zero clearance contact with microwave acted tissue. The method is reliable, the structure is stable, the linearity is good, and the sensitivity is high. By the aid of the reliable and effective temperature measuring mode, the key technology that the temperature is measured in real time while the semi-rigid water cooling microwave ablation antenna performs microwave hyperthermia or microwave ablation in cavities, intestines or blood vessels and even hearts is achieved, and accordingly, powerful guarantee is provided for obtaining of the optimum curative effect and the application expansion, and favorable conditions are provided for the intelligence 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...
