Stammberger Circular Punches

Stammberger Circular Punches – 3.5mm and 4.5mm FESS Cup Cutting Forceps

Pak Line Industries presents the Stammberger Circular Punches a high-precision endoscopic sinus surgery instrument engineered for clean circular punch excision, ostium enlargement, and atraumatic mucosal removal during Functional Endoscopic Sinus Surgery (FESS). Designed with an elongated, slender shaft profile and razor-sharp circular cutting cup jaws, this instrument gives surgeons direct micro-mechanical control to create circular fenestrations in the maxillary, sphenoid, and frontal sinus ostia while preserving adjacent healthy respiratory mucosa to prevent scar stenosis.

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 ensure long-term edge sharpness, zero shaft deflection, and superior corrosion resistance. Equipped with an ergonomic spring-action pistol/bayonet ring handle, the punch drops the clinician’s hands completely below the visual axis of the rigid endoscope, ensuring unobstructed panoramic visualization down narrow nasal corridors. Fully reusable, rustproof, and 100% steam autoclavable, it meets the demanding standards of hospital operating rooms, sinus surgery centers, and global surgical distributors.

Key Features & Surgical Performance Advantages

• True Circular Cup Cutting Geometry: Precision-milled 3.5mm and 4.5mm hollow circular cup heads deliver a clean, $360^\circ$ shearing cut through bony lamellae and mucosal tissue without tearing or stripping margins.

• Preservation of Mucociliary Clearance: Clean circular resection minimizes postoperative synechiae formation and scarring around vital drainage pathways.

• Low-Profile Slender Shaft: Slim working shaft passes smoothly alongside $0^\circ$, $30^\circ$, and $45^\circ$ rigid endoscopes within narrow nasal channels without visual crowding.

• Angled Ergonomic Handle Offset: Drops the surgeon’s hand below the line of sight to allow clear endoscopic camera views and prevent instrument collision in tight spaces.

• Sensitive Spring-Return Mechanism: Internal leaf spring provides smooth, fatigue-free recoil and micro-metric tactile control during repetitive tissue excisions.

• AISI 420 Surgical Stainless Steel: High-carbon martensitic alloy hardened to HRC 50–54 prevents edge micro-fractures and ensures lasting structural rigidity.

• 100% Steam Autoclavable & Reusable: Engineered to endure repeated high-temperature hospital sterilization cycles (134°C / 273°F) without dulling or mechanical stiffness.

• OEM & Custom Specification Services: Available in standard 3.5mm and 4.5mm cutting diameters with straight, curved, or upturned shaft options, custom laser etching, and bulk export packaging.
