Yes, tungsten needles can be used for microsurgery applications due to their high strength, rigidity, and sharpness. Tungsten needles are commonly used in ophthalmic surgery for procedures such as vitrectomy and retinal detachment repair, as well as in neurosurgery for procedures such as biopsy and deep brain stimulation. Their high precision and fine tip allow for greater accuracy and control during surgical procedures. Tungsten needles can also be used for microsurgical procedures in other medical specialties, such as plastic surgery and urology.
