Low temperature plasma ablation

Because the therapeutic warhead of this technology is only about 10 micron to 1 mm, and some of them are thinner than hair, it is also called "hair technology".

Low-temperature plasma technology is to use plasma low-temperature ablation system to instantly ablate the hyperplastic tissue causing rhinitis under nasal endoscope, which can maintain the safety of local mucosal tissue structure and effectively reduce postoperative edema and pain. Low-temperature plasma ablation is called "DNR digital low-temperature plasma ablation" in the United States, and DNR is literally translated into Donier in English, so it is called "Donier low-temperature ablation" for short. This technology comes from the high-energy military plasma technology of the US military, and was originally mainly used for the study of cosmic nuclear energy and charged particles. Because the therapeutic warhead of Dornier technology is only about 10 micron to 1 mm, and some of them are thinner than hair, it is also called "hair technology".

Dornier cryoablation is the most advanced medical instrument and the latest fourth-generation physical therapy technology. Because of its excellent clinical performance, it has completely replaced the traditional treatment methods such as surgery, laser and microwave in developed countries such as the United States and Europe. Medical experts agree that digital plasma treatment technology represents the highest level today.

The basic principle of Donier cryoablation is cryoablation, that is, using the energy of low-temperature plasma radio frequency, the tissue is removed at a lower temperature (40-70 degrees), thus avoiding the damage to the tissue, greatly alleviating the pain of patients and shortening the recovery period. In recent years, low-temperature plasma ablation system has been widely used in the field of otorhinolaryngology abroad, and its clinical effect has also been recognized by world authorities.

Dornier digital cryoplasma therapeutic instrument is not an ordinary device. Compared with microwave, this technology has no radiation, can work in blood, has lower temperature and better therapeutic effect. Compared with radio frequency, it has lower frequency and temperature, more stable operation, and has the function of ion liquefaction. Compared with electric knife, it can cut in blood, and the cutting effect of cold knife is no heat source damage; Compared with laser, it has the advantages of arc cutting, no reflection, little peripheral damage and strong cutting power. It is the most advanced high-tech equipment for treating otolaryngology diseases in the world. Low temperature plasma technology is a relatively mature and booming applied discipline, which has been widely used in traditional and high-tech fields. Among them, plasma surface modification technology solves the problem that synthetic polymer materials can not fully meet the requirements of biocompatibility and high biological function as biomedical materials with its unique advantages. After plasma treatment, bioactive molecules can be fixed on the surface of polymer materials to achieve the purpose of being used as biomedical materials.

Low temperature plasma is the fourth state of matter after solid, liquid and gas. When the applied voltage reaches the ignition voltage of the gas, the gas molecules are decomposed to produce a mixture including electrons, various ions, atoms and free radicals. Although the electron temperature is very high during the discharge process, the heavy particle temperature is very low and the whole system is in a low temperature state, so it is called low temperature plasma. This technique is to instantly ablate the hyperplastic tissue causing rhinitis by using the imported plasma cryoablation system under the nasal endoscope, which can not only keep the safety of local mucosal tissue structure, but also effectively reduce postoperative edema and pain. The ablation time is very short, about 15-20 minutes, and the symptoms are relieved after operation. Generally, it will not recur after operation, and can effectively treat allergic rhinitis, chronic rhinitis, snoring and pharyngitis.

During the treatment, Dornier's therapeutic warhead will first collect the basic data of the diseased tissue by using the digital intelligent identification function, and then according to the instructions of the computer, make the tissue form a space with uncharged ionized substances, including ions, electrons and core particles (the number of ions of free electrons and anode electrons in this space is almost the same, so we call it plasma). At this time, the unbalanced plasma with high energy absorption will produce low-temperature decomposition effect and RL (inductive reactance) thermal effect on the diseased tissue under the control of computer program, even if the protein of the tissue is rapidly solidified, the blood vessels will contract and seal, thus achieving the purpose of treating otorhinolaryngology diseases. During the treatment, the mucosa and ciliated epithelium of the patient's ear, nose and throat will hardly be damaged. Therefore, patients will recover better after surgery than patients undergoing traditional otolaryngology surgery.

Because Dornier's therapeutic warhead is thin but very strong, doctors can trim and bend the warhead as needed. With the cooperation of the advanced Storz nasal endoscope system in Germany, the warhead can easily reach the focus of any part of otorhinolaryngology, so Donier's cryoablation can be used to treat almost all otorhinolaryngology diseases.

Donier digital low-temperature plasma ablation in the United States is an advanced treatment equipment for nasopharyngitis in the world at present, and the plasma low-temperature ablation treatment system is a nearly perfect minimally invasive treatment method for nasal diseases. Under the action of low temperature, the diseased part of turbinate hypertrophy was melted without damaging the normal turbinate mucosa, thus achieving the therapeutic purpose. The principle of low-temperature plasma ablation therapy system is to form a thin plasma layer between the electrode and the tissue, and the ions in the layer are accelerated by the electric field and the energy is transferred to the tissue. At low temperature (40℃-70℃), the molecular binding bonds between cells are opened, so that the cells in the target tissue are decomposed into carbohydrates and oxides, causing liquefaction and ablation of the diseased tissue. This phenomenon is called plasma (non-thermal effect), thus achieving the effect of volume reduction of the target tissue.

The cryogenic plasma treatment system uses the digital intelligent identification function to collect the data of the treated tissue first, and then according to the instructions of the computer, the tissue will generate steam instantly. Under the action of digital high-frequency alternating electric field, these tissues will be rapidly excited and ionized, and the diseased tissues will be rapidly ablated at low temperature, contracting and sealing blood vessels. Because of the ultra-low working temperature, the ablation depth can be accurately controlled, and the cutting warhead smaller than human hair is used, the damage to surrounding tissues during the operation is very small. This technique can ensure the integrity, safety and painless of mucosa when treating rhinitis, and avoid the recurrence of nasal diseases; Moreover, disposable therapeutic probes are used to prevent cross-infection between doctors and sources; The whole treatment process only takes about 20 minutes, which is very suitable for busy people, white-collar workers, students and people who are sensitive to pain.
