Appearance: The sharp tip of the needle brings minimal pain to the patient during the puncture; the zero-thickness transition zone between the exposed end and the insulating layer brings a lubrication sense and a precise feel to the puncturing process and makes the puncture more accelerated, smooth and accurate, reducing patient discomfort. Accurate, reduce patient's discomfort, improve the accuracy and safety of surgery. Disposable sterile packaging, valid for 5 years. There are also domestic after-sales Beijing Beiqi Medical Technology Co., Ltd. information p><strong> the main core of the radiofrequency trocars </strong></p><p><strong> Beiqi radiofrequency trocars </strong> combining the conventional radiofrequency needle The new product is produced. Beiqi radiofrequency trocars have the same advantages as radiofrequency needles. But for the patient, Beiqi radiofrequency cannula can be two surgeries into one, which greatly reduces the patient's pain, and at the same time for the doctor to reduce the labor intensity and reduce the cost of surgery. <br/> Beiqi radiofrequency trocars are also what you call radiofrequency needles also called radiofrequency puncture needles for radiofrequency thermocoagulant surgery when the use of puncture needles, the needle coating is used PET heat shrinkable tubing (polyester heat shrinkable tubing) from the heat resistance, electrical insulation properties, mechanical properties are greatly more than the pvc heat shrinkable tubing, and more importantly PET heat shrinkable tubing is non-toxic, easy to recycle, no toxic effects on the human body and the environment, no toxic effects. And the environment will not produce toxic effects, more in line with environmental requirements. <br/>PET heat shrinkable tubing environmental performance is higher than the EU RoHs directive standards, can reach Sony SS-00259 environmental standards. It does not contain cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBBEs/PBDEs), polychlorinated biphenyls (PCBs), polychlorinated terphenyls (PCTs), polychlorinated naphthalenes (PCN) and other banned substances of the 1st level of environmental management, and it is the best choice for the outer wrapping of electrolytic capacitors, inductors and other electronic components, high-grade rechargeable batteries, toys and medical devices, can fully meet the export requirements, you can rest assured that it can be used. </p><p> Beiqi's RF casing needles, needle core is made of stainless steel, the needle tube is also made of stainless steel, but the needle tube has a layer of polyester heat-shrinkable tubing, which can be referred to the insulation protection and polyester heat-shrinkable tubing a very environmentally friendly material, are generally used in medical devices
