What Are The Structural Features Of Medical Puncture Needles?

Radiofrequency puncture needle and radiofrequency trocar are disposable sterile products, which are used together with radiofrequency temperature-controlled thermocondenser. Puncture used during radiofrequency thermocoagulation of tissues such as nerves and muscles. Under sterile conditions, remove the radiofrequency puncture needle the radiofrequency trocar. Before use, ensure that the length and diameter of the surgical electrode are suitable for the length of the radiofrequency puncture needle and the radiofrequency trocar. Please refer to the specification and size of the radiofrequency thermo-condenser manufacturer's manual. If you are not sure, remove the lining in the trocar of the RF thermocoagulation electrode from the needle tube and insert the electrode into the needle tube for verification. At this point, if the tip of the electrode is just out of the needle tube and is located in the middle of the needle tube end slope, and the electrode is not loose, the optic electricity is very suitable. Make sure the lining fits the needle tube correctly. Percutaneous puncture was performed using a trocar with radiofrequency thermocoagulation electrodes until the tip of the needle reached the target position. Gently remove the lining from the needle and insert the surgical electrode.
