High pressure argon helium knife treatment technology

    The cryotherapy of tumors by high-pressure helium gas and high-pressure argon gas uses ultra-low temperature generated by high-pressure argon gas and high-pressure helium gas to denature tumor cells, ischemia and hypoxia, cause cell death, and rapidly form irreversible coagulability. Necrotic frozen area, less damage to adjacent large vessels. In recent years, the development of argon-helium knife to the treatment system can be used to percutaneously puncture liver cancer and tumor under ultrasound or CT guidance. The rapid release of high-pressure argon gas produces ultra-low temperature of minus 140 degrees Celsius, followed by high-pressure helium gas to produce 45-degree thermal effect, maximally destroying cancer. Compared with traditional surgical treatment, the treatment of argon-helium technique with high-pressure helium and high-pressure argon is a minimally invasive treatment for liver cancer. Due to its simple operation, less complications, and repeatability, with the advancement of imaging technology, the treatment of hepatic tumors with high-pressure helium and high-pressure argon will further develop, in order to lose the opportunity for surgical treatment. Liver cancer patients bring new hope.

Naughty N2O--anesthesia analgesia extraction

Laughing and painless childbirth has been widely used in many obstetrics and gynaecology. Laughing is a gas that can alleviate the pain of childbirth. It contains half of oxygen and half of nitrous oxide. It can be used in normal delivery to achieve painless delivery. Recently, laughing gas anesthesia and pain relief have also gained new applications in dentistry. When you lift your teeth, you will always be afraid of the surgical instruments such as dental extraction forceps. Many patients in the clinic have dental fears, especially children, to varying degrees.

In order to solve the fear and anxiety of the patient's teeth, the existing "oral laughing and analgesic system" applied to dentistry on the market makes the teeth easier and more comfortable. The system consists of a "laughing gas" (nitrous oxide N2O) inhalation of a calming analgesic machine, a dental chair cinema, a multi-function monitor and an exhaust gas recovery device. Laughing gas is the first anesthetic gas discovered. It is non-toxic and tasteless, and has no adverse effects on the nervous system and heart, lung, liver and kidney. It is very safe. The doctor inhales a small amount of laughter through the calming analgesic machine, so that the anxiety and nervousness of the patient are quickly relieved. The patient was lying on a dental chair and wearing 2D/3D glasses (a dental chair cinema, a digital product imported from the United States) while taking a movie and listening to music while receiving dental treatment. The entire treatment was successfully completed without knowing it. The instrument uses a multi-parameter monitor to automatically collect patient respiratory, blood pressure, electrocardiogram and blood oxygen saturation data to ensure patient safety.

Excimer laser cesium fluoride 308nm treatment of vitiligo

Since the excimer laser was developed in the 1980s, the excimer laser has been transformed from civilian technology to civilian use so far, and has been widely used in various fields. The cesium chloride (XeCI) excimer laser is a laser generated by a mixture of Xe, HCl, H2, and Ne gas in a certain ratio, and the 308 nm laser is generated. Chlorine Cl is a halogen element, and 氙Xe is an inert gas. Under normal conditions, chlorine and ruthenium do not react, and there are no chlorine and ruthenium compounds in nature, but pre-ionization pumping at high pressure and strong electric field. Under the action, chlorine can accept an electron of ruthenium to form a ruthenium chloride molecule. The ruthenium chloride is unstable for a short period of time and will soon dissociate into chlorine and ruthenium. This unstable molecule is called excimer. The laser generated by the excitation of the unstable ruthenium chloride excimer is an ultraviolet laser having a wavelength of 308 nm.

The cesium chloride XeCl 308nm excimer laser was originally developed by the US military for the military field, because it has been found to treat skin diseases. The US FDA has been used in the field of dermatological treatment since 2000!
