Medical tungsten needle refers to a type of slender tool used in the medical field for puncture, sampling or minimally invasive surgery. Its manufacturing material is tungsten or tungsten alloy. These tungsten needles play a key role in medical procedures and their key features include:
1. Puncture and Sampling: Medical tungsten needles are often used for puncture and tissue sampling. Doctors can use these tungsten needles to penetrate a patient’s skin, reach specific tissues or organs, and then take samples for laboratory testing. Because tungsten has a high melting point and hardness, such tungsten needles are often able to penetrate different types of tissue while maintaining their structural integrity.
2. Minimally invasive surgery: Tungsten needles are also commonly used in minimally invasive surgery, in which doctors enter the patient’s body through small incisions or natural orifices for treatment or diagnosis. Due to the hardness of tungsten, such tungsten needles can provide highly precise control during surgery.
3. Radiation therapy: Tungsten needles can also be used in radiation therapy to provide local treatment by inserting the tungsten needle into the tumor tissue. This method, sometimes called “tungsten needle radiotherapy,” uses tungsten’s ability to absorb radiation so that tumor tissue can be treated more effectively.
4. Other medical applications: Tungsten needles can also be used in some other medical applications, such as neurosurgery, endovascular interventional surgery, etc. Its high hardness and corrosion resistance make it ideal for some specific medical procedures.
