The Automatic Biopsy Gun segmentation by application distinguishes four principal clinical domains: Oncology, Pulmonology, Gastroenterology, and Other specialties. Oncology commands the largest share, driven by the high incidence of solid tumors and the need for precise core sampling in breast, prostate, and liver lesions; it accounts for roughly 45 % of total market revenue. Pulmonology, representing about 30 % of the market, reflects the growing demand for minimally invasive lung biopsies, particularly for peripheral nodules identified via CT guidance. Gastroenterology contributes 15 % as endoscopic and percutaneous approaches become standard for pancreatic and gastrointestinal tract lesions. The residual Other segment, at 10 %, aggregates niche uses in urology, orthopedics, and veterinary applications, each adding incremental volume. Collectively, these application categories shape the overall market size by allocating capital investment, R&D focus, and sales effort proportionally to clinical demand and procedural frequency.
