Stammberger Antrum Punch

Stammberger Antrum Punch (Backward / Retrograde Cutting) – Endoscopic Sinus Surgery Forceps

Pak Line Industries presents the Stammberger Antrum Punch, an essential micro-surgical through-cutting instrument engineered for precise retrograde bone excision, uncinectomy completion, and natural maxillary ostium enlargement during Functional Endoscopic Sinus Surgery (FESS). Designed with a slender shaft and a backward-cutting through-bite punch tip, this instrument allows ENT surgeons to excise thin bony margins and hyperplastic mucosa in reverse orientation, safely opening the maxillary antrum from posterior-to-anterior without traumatizing anterior lacrimal pathways.

Manufactured in our ISO 13485:2016 certified production facility in Sialkot, this instrument is hot-drop forged from premium medical-grade AISI 420 Surgical Stainless Steel and vacuum heat-treated to HRC 50–54 to guarantee lasting edge sharpness, high torsional rigidity, and resistance to jaw deflection. Engineered with an offset spring-loaded pistol ring-handle chassis, it lowers the operator’s hands below the line of sight to maintain clear panoramic visualization alongside rigid endoscopes. Fully reusable, rustproof, and 100% steam autoclavable, it meets the demanding performance requirements of hospital operating theaters, ambulatory sinus centers, and global surgical distributors.

Key Features & Surgical Performance Advantages

• Retrograde (Backward-Cutting) Punch Mechanism: Specially designed backward-oriented cutting jaw allows clean enlargement of the maxillary sinus fontanelle and uncinate margin from behind, avoiding anterior tissue tears.

• Clean Through-Cutting Shear Action: Precision-machined cutting anvil produces clean mechanical cuts through bone and mucosa without stripping surrounding sinus lining, preserving healthy mucociliary clearance.

• Low-Profile Slender Shaft: Slim shaft profile permits effortless navigation through narrow nasal corridors and middle meatal spaces alongside $0^\circ$, $30^\circ$, or $70^\circ$ rigid endoscopes.

• Ergonomic Offset Pistol-Ring Handle: Angled handle chassis drops the surgeon’s hand below the optical pathway, preventing camera interference and preserving direct visualization.

• Responsive Spring-Action Recoil: Integrated spring return mechanism ensures smooth opening and closing cycles, reducing surgeon hand fatigue during repetitive punch excision.

• Medical-Grade AISI 420 Stainless Steel: Martensitic alloy hardened to HRC 50–54 prevents cutting edge wear, structural deformation, and micro-fractures under mechanical pressure.

• 100% Steam Autoclavable & Reusable: Resists repeated hospital autoclaving cycles (134°C / 273°F) and ultrasonic cleaning protocols without mechanical stiffness or corrosion.

• OEM & Custom Specification Services: Available in multiple punch bite sizes and cutting orientations (backward-cutting, backward/upward, backward/right/left) with custom laser marking and export packaging.
