Trocars and biopsy needles are essential medical instruments used in minimally invasive procedures. Trocars are sharp-pointed instruments equipped with a sleeve, enabling surgeons to access internal organs or cavities through small incisions during laparoscopic surgery. Biopsy needles, on the other hand, are slender, hollow tools designed to extract tissue samples for diagnostic examination or research purposes. Together, these instruments play a crucial role in modern medical interventions, facilitating precision, efficiency, and patient comfort in diagnostic and therapeutic procedures.
