With the rapid development of medical technology, tumor diagnosis and treatment technology has also made considerable progress. The Medical Device Innovation Website will make an inventory of 5 kinds of leading-edge tumor minimally invasive diagnosis and treatment technologies and the related companies.

 

1.  HIFU

Professional name: high intensity focused ultrasound tumor therapy system (HIFU)

Treatment principle:

High energy ablation effect by acoustic energy accumulation 

Treatment approach:

Direct ultrasound guided treatment, without insertion of electrodes into tissue. It can make the low energy ultrasound in vitro to accumulate at the in vivo lesion of the tumor, and produce the instant high temperature at the focal point, reaching the purpose of killing the tumor tissue.

Manufacturers:

Beijing Deyuan,ShanghaiAishen,ShanghaiJiaotongUniversityXindi,ChongqingHIFU, etc.



2. Cryosurgery 

Professional name: low temperature frozen operation system 

Treatment principle:

Ablation effect of cold and hot circulation by freezing and ablation of high pressure argon gas and high pressure helium gas on the lesion tissue in short time 

Treatment approach:

Under the imaging guidance, insert into the lesion by the skin puncture, and adjust the output power and freezing time to control the size of the frozen ball in the cell after rapid cooling, and make the tumor cells to rupture by using the principle of thermal expansion and contraction, so as to achieve the purpose of treatment.

Manufacturers:

Israel GALIL Medical Company, American Endocare Company



3. Radiofrequency

Professional name: high-energy radiofrequency ablation (RFA) 

Treatment principle: 

RF thermal curing and vaporization effect 

Treatment approach: 

Under the guidance of ultrasound or CT, insert into the tumor by puncture, and can release 10 pieces of umbrella shaped electrode covering the tumor range with the diameter of 5cm, make the local tissue temperature to reach high temperature through alternating RF current, resulted into the necrosis of the tumor tissue, so as to achieve the purpose of treatment.

Manufacturers: 

International brands: RITA, Medsphere,OLYMPUS, COOL-TIP/HiTT, etc.

Domestic brands: Erfu, Lide, Zhuhai Hejia, Bo Lai De, Tianma, etc.

4. Microwave

Professional name: Microwave multi-function operation treatment

Treatment principle:

Microwave heat curing effect

Treatment approach:

Insert into the tumor body to heat under the direct vision or by percutaneous puncture in the operation, formed a curing area with the size of 4cm*3cm, and make the local temperature to reach high temperature through microwave, resulted into the necrosis of the tumor tissue, so as to achieve the purpose of treatment.

Manufacturers:

Nanjing Yigao, Qiya, Kangyou, Great Wall, etc.


5.Particles

Professional name: stereotactic radiotherapy system

Treatment principle: 

Particles implantation, all of the isotope source: iodine 125, palladium 103, etc. 

Treatment approach: 

Implant the particles into the tumor by the particle growing gun and other technologies, and kill the tumor cells through the continuous release of low energy γ rays, so as to achieve the purpose of the treatment. Because the tissue penetration distance of the ray is 1.7cm, it has less influence on the surrounding normal tissue, so as to achieve the purpose of accurate radiotherapy.

Manufacturers:

American prowess, Zhuhai Hejia, Beijing Tianhang Kelin, Guangzhou Hangshi Medical Image, etc.
