What Are the Applications of Tungsten Wire in Medical Equipment?

Tungsten wire has a variety of applications in medical devices that take advantage of its properties, including its high melting point, corrosion resistance, and electrical conductivity. Here are some common applications of tungsten wire in the medical field:

X-ray tubes: Tungsten filaments are widely used in X-ray tubes, which are used in medical imaging equipment such as X-ray machines and computed tomography (CT) machines. Tungsten wire is used as a cathode in an X-ray tube. When heated, the hot electrons produced form an electron beam, which is used to generate X-rays.

Electrocoagulation: Tungsten wire is used as the electrocoagulation electrode in electrocoagulation. During surgery, doctors can use electrocoagulation electrodes to coagulate tissue or blood vessels with high-frequency current to control bleeding or cut tissue.

Endoscope: In the lighting system of endoscope, tungsten filament is used to make high-brightness fiber optic light. These fiber optic lights are used to illuminate the endoscope’s field of view so doctors can perform examinations or procedures.

Laser Cutting and Welding: High-energy laser systems often use tungsten filaments as part of their fiber optics for laser cutting and laser welding. These technologies are widely used in medical device manufacturing and surgery.

Medical device connectors: Tungsten wire is used in medical device connectors to ensure reliable electrical connections, such as in pacemakers and other implantable medical devices.

Electrosurgery: Electrosurgery is used to cut and coagulate tissue during surgery. Electrosurgical electrodes usually contain tungsten wires, which generate heat through high-frequency current for surgical operations.

Fluorescence Microscopy: In biomedical research, fluorescence microscopy often uses tungsten filaments as a light source to observe and study cells and tissues.

Radiation Therapy: Tungsten wire is also used in some radiation therapy equipment to produce radiation in cancer treatment.
