Minimally invasive tungsten needle is a special surgical tool commonly used in fields such as neuroelectrophysiology research and tumor treatment. It is made of pure tungsten or tungsten alloy, has a very high melting point and hardness, and can maintain stability at high temperatures. The head of a minimally invasive tungsten needle is usually tapered or needle-shaped, which can easily enter narrow surgical sites, and can generate high-temperature arcs to evaporate or dissolve metal materials on the surface of the workpiece to achieve precision machining.
In neuroelectrophysiology research, minimally invasive tungsten needle can be used to insert into brain tissue or nerve fibers to record electrical signals or perform electrical stimulation to explore the function and behavior of the nervous system. In tumor treatment, minimally invasive tungsten needle can be used to guide high-energy particle beams to the tumor site for precise radiation therapy.
The design and manufacturing process of minimally invasive tungsten needle is very strict and requires multiple processes and testing links to ensure that their quality and performance meet clinical requirements. This kind of needle usually needs to have characteristics such as high purity, high density, high hardness, and low conductivity to ensure that it can maintain stability and accuracy in high-temperature, high-current working environments.
