Cryo-HITTM cryogenic cryosurgery system is a product produced by Galileo, Israel. Israel Galileo is a world leader in cryotherapy equipment markets, with research and development headquarters in YOKNEAM, Israel. The Galileo Cryo-HITTM brand is the first brand in the European and American markets. The product currently has more than 400 units worldwide and has 33 patented technologies.

Cryo-HITTM cryogenic cryosurgery system was registered and approved by the Ministry of Health, Health Technology and Structure Management Agency, and Medical Device Department of Israel in 1997; it passed the CE certification of the European Community in 1999; it was registered by the US FDA in 2000, and it is the only one in the world. Approved by the FDA for cryoablation of benign and malignant tumors in multiple systems including liver, lung, breast, uterus, kidney, prostate, nerves (including nerve analgesia) and bones; passed the China National Food and Drug Administration in May 2003 The SFDA has entered the Chinese market after registration and approval, and has been approved for use in oncology, general surgery, thoracic surgery, dermatology, otolaryngology, obstetrics and gynecology, anorectal, urology, neurology (including neural analgesia) and other departments. Cryosurgery. The Cryo-Hit cryogenic cryosurgery system SFDA is registered as "Cryo-Hit cryogenic cryosurgery system", and the registration number is Sinopharm (jin) 2003 No. 3580683.

The Cryo-HITTM cryogenic cryosurgery system consists of three parts, namely a cold-heat conversion system, a temperature monitoring system, and a cryoprobe.

The cryoprobe is a hollow and sealed puncture needle with a diameter of only 1.47mm. Inside the probe are gas pipelines, throttle nozzles, expansion space and other structures. The gas pipeline inside the probe can withstand the pressure of 3 oxygen cylinders (6000psi), and is made of high-tech alloy materials.

1.47mm frozen probes are available in a variety of models. The commonly used models can form ice balls of 4 × 6cm in size. The effective treatment range below minus 40 degrees is 1.5 × 3.5cm. Generally small tumors can be treated with a single needle, and larger tumors can be treated with multiple needles.

The temperature sensor in the probe above 2mm can monitor the temperature in the center of the freezing area. There is no temperature sensor in the 1.47mm probe. If you need to monitor the temperature, you can insert the temperature probe separately to monitor the temperature in the tissue. The monitored temperature change and freezing time can be displayed as a temperature-time curve on the LCD screen, so that the operator can understand the freezing process in time.

During treatment, puncture is usually performed under the guidance of B ultrasound, CT, and magnetic resonance, and the entire process of puncture is monitored in real time. The surgical methods include percutaneous puncture, surgical puncture under direct vision, and laparoscopic puncture. During the treatment, insert the probe into the tumor, turn on argon, freeze for 10 minutes, pause for 3 minutes, then turn on helium, and heat up for 1 minute. This treatment process is repeated once more, and the treatment process ends. It usually takes 25 hours. minute.

For early small tumors, cryotherapy can be used as an alternative to surgery. It can be used as a palliative treatment for large tumors at advanced stages, which can enhance the effect of comprehensive treatment, reduce tumor burden, reduce symptoms, improve quality of life, and extend survival time.

Cryo-HITTM cryogenic cryosurgery system has a wide range of indications for treating tumors, and is mainly applied to various solid tumors throughout the body. Including liver cancer, lung cancer, prostate cancer, kidney cancer, pancreatic cancer, benign and malignant tumors of bone, adrenal cancer,

Cryo-HITTM cryogenic cryosurgery system has the advantages of precise positioning, precise ablation, less trauma, less pain, precise curative effect, and broad indications. Compared with traditional surgery, it greatly reduces the risk and complication rate of surgery; compared with microwave and radiofrequency minimally invasive treatment methods, it can monitor the treatment process and treatment effect without the limitation of anesthesia; compared with radiotherapy and chemotherapy, It does not have the problem that tumor tissues are not sensitive to chemotherapy drugs or are limited by the maximum dose of radiotherapy. Compared with similar products, Cryo-HITTM cryogenic cryosurgery system has six advantages, that is, the only cryo-interventional therapy can be performed under the guidance of magnetic resonance, ultra-fine 1.47mm probe, 5 groups of 25 probe combination, iThaw heating Helium temperature rise, multi-point stereo monitoring temperature, and treatment planning system. The magnetic resonance compatible cryogenic cryosurgery system represents the highest technical level of this type of product, and has great innovation and advancedness. Cryo-HITTM cryogenic cryosurgery system is an internationally-advanced minimally invasive treatment device for tumor cryosurgery. It is an ideal choice for clinical tumor treatment.

The disadvantage of cryogenic cryosurgery is that tumor cells may remain at the edge of the frozen area and become a source of recurrence. Excessive freezing can cause severe complications such as organ cracking and "cold shock".
