Micro Wilde Type Back Biter

Micro Wilde Type Back Biter for 8–11cm Sinus Tissue Punch Access

Pak Line Industries presents the Micro Wilde Type Back Biter for 8–11cm Sinus Tissue Punch Access, an advanced retrograde micro-cutting surgical punch engineered for uncinectomy, anterior ethmoid clearance, and maxillary ostium enlargement during Functional Endoscopic Sinus Surgery (FESS). Built with an anatomically curved, low-profile working shaft and a backward-cutting through-bite punch tip, this instrument allows ENT surgeons to resect thin bone lamellae and mucosal tissue in reverse orientation from behind the uncinate process without traumatizing anterior structures or obscuring endoscopic visualization.

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 durable edge sharpness, torsional stiffness, and maximum resistance to tip deflection. Featuring a rotatable/indexable shaft collar mechanism and an ergonomic spring-action pistol ring-handle chassis, the punch drops the clinician’s hands completely below the optical pathway to ensure clear illumination alongside rigid endoscopes. Fully reusable, rustproof, and 100% steam autoclavable, it meets the exacting clinical standards of hospital operating theaters, ambulatory sinus centers, and international surgical distributors.

Key Features & Surgical Performance Advantages

• Retrograde (Back-Biter) Cutting Action: Backward-facing punch jaw safely resects the uncinate process and widens the maxillary sinus ostium from posterior-to-anterior without tearing mucosal margins.

• Anatomically Curved Distal Shaft: Curved shaft geometry effortlessly maneuvers around the middle turbinate and reaches deep into the middle meatus without mucosal abrasion.

• $360^\circ$ Rotatable Shaft Collar: Integrated finger wheel/collar enables full rotational positioning of the cutting tip without changing the surgeon’s hand grip.

• 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 (8–11 cm Reach): Slim working shaft passes smoothly alongside $0^\circ$, $30^\circ$, and $70^\circ$ rigid endoscopes within narrow nasal corridors without visual crowding.

• 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.

• AISI 420 Surgical 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 standard punch bite sizes and orientations with custom laser marking, CE compliance, and bulk export packaging.
