Millised on RF-trokaarite omadused?

Appearance: The sharp needle tip brings minimal puncture pain to the patient; the zero-thickness transition belt between the exposed end and the insulating layer brings a lubricating and precise feel to the puncture process, making the puncture more smooth and accurate, reducing the patient's pain. Discomfort, improve the accuracy and safety of surgery. Disposable sterile packaging, valid for 5 years. RF trocars have the same advantages as RF needles. But for the patient, the radio frequency trocar can turn two operations into one operation, which greatly reduces the pain of the patient, reduces the labor intensity for the doctor, and reduces the operation cost. Radio frequency trocar is also called radio frequency needle or radio frequency puncture needle. It is used for puncture needle used in radio frequency thermocoagulation operation. The coating of the needle is made of PET heat shrinkable tube (polyester heat shrinkable tube). Heat resistance, electrical insulation performance, and mechanical properties all greatly exceed pvc heat shrinkable sleeves. More importantly, PET heat shrinkable sleeves are non-toxic, easy to recycle, have no toxic impact on human body and the environment, and are more in line with environmental protection requirements. . RF trocars, the needle core is stainless steel, and the needle tube is also stainless steel, but the needle tube has a layer of polyester heat-shrinkable tube, which can be mentioned as insulation protection, and polyester heat-shrinkable tube is a very environmentally friendly material, which is generally used in on medical devices
