Puncture needles are indispensable basic precision instruments in modern clinical medicine, covering the entire diagnosis/treatment chain including disease screening/diagnosis, targeted drug delivery, minimally invasive treatment, and sample research. They are core tools in scenarios such as tumor screening, internal medicine diagnosis/treatment, surgical minimally invasive procedures, and vaccination. With their characteristics of being minimally invasive, precise, and safe, puncture needles are gradually replacing traditional invasive diagnosis/treatment methods, becoming core instruments for standardized operations in medical institutions at all levels, supporting the precise and standardized development of clinical medicine.

In the field of disease diagnostic sampling, puncture needles serve as the core carrier for pathological diagnosis. Clinically, tumor screening, organ lesion detection, and bodily fluid pathological analysis all rely on puncture sampling techniques. Specialized instruments such as EBUS-TBNA puncture needles and soft tissue biopsy needles can accurately puncture lesion areas in organs like the thyroid, breast, lungs, liver, and kidneys to extract complete tissue and bodily fluid samples. Compared with traditional open sampling, puncture sampling causes minimal trauma, offers high precision, and yields highly intact samples. It can provide an accurate pathological basis for distinguishing benign from malignant tumors, typing chronic disease pathologies, and staging diseases, serving as a prerequisite core link in early cancer screening and precise diagnosis/treatment of chronic diseases. Currently, over 60% of clinical minimally invasive sampling surgeries are performed using puncture needles, making them a key support for early diagnosis and treatment of diseases.

In clinical drug delivery and treatment scenarios, puncture needles enable painless and targeted administration. Traditional intramuscular and intravenous injections cause strong pain, and the diffusion range of drugs is uncontrollable. In contrast, micro puncture needles can achieve painless drug delivery, avoiding the stinging sensation and discomfort of traditional injections. In pain management, local inflammation treatment, and targeted intervention for chronic diseases, puncture needles can deliver drugs directly to the depths of the lesion, increasing local drug concentration, enhancing therapeutic effects, while reducing side effects caused by systemic medication. Their safety and adaptability advantages are particularly prominent in scenarios such as vaccination and targeted physiotherapy, meeting the diagnosis/treatment needs of various populations including adults and children.

The application of puncture needles continues to expand in the field of minimally invasive interventional therapy. In departments such as urology, gynecology, orthopedics, and oncology, puncture needles, working in conjunction with minimally invasive interventional equipment, can perform minimally invasive operations such as puncture drainage, effusion cleaning, local ablation, and brachytherapy. For example, prostate brachytherapy puncture needles and radiofrequency puncture needles can achieve precise local treatment of tumors without the need for surgical excision of lesions, greatly reducing surgical risks and postoperative complications, and are especially suitable for elderly, frail patients who cannot tolerate major surgeries.

At the same time, puncture needles are widely used in medical research and animal experiments, providing precise substance introduction and sample extraction services for biological specimens and experimental models, assisting in new drug development, pathological mechanism research, and clinical trials of medical devices. Additionally, in the field of veterinary medicine, standardized puncture needles are gradually becoming popular, standardizing animal disease sampling, drug administration, and minimally invasive treatment operations.

As fundamental instruments for clinical minimally invasive diagnosis/treatment, puncture needles run through the entire chain of diagnosis, treatment, and research, effectively solving the pain points of traditional diagnosis/treatment such as large trauma, low precision, and slow recovery. As clinical diagnosis/treatment standards continue to upgrade, the variety of puncture needle subcategories continues to improve, adapting to more difficult disease minimally invasive diagnosis/treatment scenarios, continuously enhancing clinical medical efficiency and patient medical safety guarantees.
