Stammberger Circular Punches SKU PS-O T-01482, model PS-5292, are reusable ENT punch instruments manufactured from German stainless steel for circular tissue cutting during endoscopic sinus surgery. The available circular cup patterns include PS-5292 3.5mm cup straight with 7-5/8 inch (19.5cm) working length and PS-5292 4.5mm cup straight with 7-5/8 inch (19.5cm) working length. These instruments are used in functional endoscopic sinus surgery, maxillary antrostomy refinement, ethmoid sinus tissue removal, antral window shaping, nasal polypectomy margin control, and revision sinus procedures requiring a defined circular bite. The long straight shaft, small distal cup, angled transition near the handle, pivoted ring handle, and closing jaw mechanism support controlled work through narrow nasal corridors under endoscopic visualization. ENT surgeons, rhinologists, otolaryngology teams, hospitals, ambulatory surgery centers, and sinus clinics select this punch pattern for precise access where standard grasping forceps do not provide a measured circular tissue bite.
The instrument uses a long straight shaft to reach the middle meatus, ethmoid region, and maxillary ostium while keeping the surgeon's fingers outside the endoscopic working channel. The circular distal cup creates a defined punch profile, allowing the surgeon to remove a controlled tissue segment rather than pulling tissue away from the operative site. Its straight working path is useful when the target margin lies directly ahead of the endoscope and the surgeon needs stable alignment with minimal shaft rotation. The ring handles provide familiar forceps-style control, while the pivot converts hand compression into a closing bite at the distal cup. The angled transition near the handle improves working clearance around the nasal vestibule and mouth-side hand position. The small circular jaw helps isolate mucosa, polypoid tissue, scarred ostial edge, or thin residual tissue under direct visualization. This mechanical design supports repetitive, measured bites during FESS.
During functional endoscopic sinus surgery, the punch is introduced after exposure, decongestion, and identification of the target sinus pathway. In maxillary antrostomy refinement, the circular cup can be placed on residual mucosal edges, posterior fontanelle tissue, or selected margins of the created window. During ethmoid work, the straight shaft supports forward access to tissue remnants that require a clean bite without broad lateral instrument movement. In revision sinus surgery, the device assists removal of scarred tissue, fibrotic membranes, or obstructive polypoid margins that narrow the surgical corridor. The circular cutting profile is useful when the surgeon needs a predictable tissue aperture rather than irregular grasp-and-tear removal. In nasal polypectomy support, it can trim localized polypoid tissue close to the sinus opening. The instrument is handled under endoscopic control alongside suction, elevators, seekers, and complementary forceps used in staged FESS workflow.
The 3.5mm circular cup is selected for smaller tissue bites in narrow nasal anatomy, confined ethmoid access, tight maxillary ostium margins, and revision fields where scar tissue limits working space. Its smaller bite diameter supports controlled trimming close to delicate landmarks and helps the surgeon work incrementally near the natural drainage pathway. The 4.5mm circular cup is selected when the field allows a wider bite and the goal is faster removal of obstructing tissue or enlargement of a prepared opening. It is useful during broader maxillary antrostomy shaping, polypoid tissue reduction, and antral window refinement after the access path is established. Both versions share the same straight 19.5cm working length, ring handle actuation, and reusable stainless steel structure. Selection depends on nasal corridor width, tissue thickness, endoscopic line of sight, and the required diameter of each bite during the procedure.
German stainless steel construction provides the shaft rigidity and jaw stability required for repeated circular punch action in ENT operating rooms. The reusable design allows integration into sinus surgery trays, rhinology procedure sets, and hospital instrument inventories. Satin, dull, or mirror finish options support visual inspection after cleaning and help clinical teams identify debris around the distal cup, pivot, and handle surfaces. Standard reprocessing includes manual cleaning, ultrasonic cleaning where used by the facility, drying, inspection, and autoclave sterilization according to hospital protocol for stainless steel surgical instruments. The product is listed as a Class I instrument with CE, ISO 13485, and FDA procurement support. These records help hospitals, clinics, and distributors manage regulated purchasing, vendor approval, and operating room tray documentation. MOQ is 1 piece, OEM orders are available, and return or replacement service supports routine procurement planning.

How are Stammberger Circular Punches different from Stammberger Antrum Punches?
Stammberger Circular Punches use a straight circular cup jaw for defined round tissue bites. Stammberger Antrum Punches use side-specific and upside-down jaw orientations for directional maxillary antrum access. The circular pattern is selected when the target lies in a forward working line and the surgeon needs a measured cup bite. Antrum punches are selected when the cutting edge must face right, left, or reverse-angle margins. Stammberger Circular Punches are useful for FESS tissue trimming, ostial refinement, and polypoid tissue removal. The antrum pattern is more focused on side-directed antrostomy margin work.
Which cup size is selected for FESS tissue punching?
The 3.5mm cup is selected for narrow access, smaller ethmoid targets, tight maxillary ostium edges, and revision cases with limited working space. It allows incremental tissue removal where the surgeon wants a smaller bite diameter. The 4.5mm cup is selected when the operative field allows broader tissue capture. It is useful during maxillary antrostomy enlargement, antral window shaping, and removal of larger polypoid tissue segments. Stammberger Circular Punches share the same 19.5cm straight working length across these cup options. Selection depends on the target site, tissue thickness, endoscopic access angle, and required bite size.
Do these punches support CE, ISO 13485, and FDA procurement context?
Yes, Stammberger Circular Punches are listed with CE, ISO 13485, and FDA procurement support. CE marking assists facilities requiring conformity records for surgical instruments. ISO 13485 alignment supports medical device quality management expectations for purchasing and distribution. FDA procurement support helps hospitals, clinics, and distributors maintain regulated vendor documentation. The product is listed as a Class I reusable surgical instrument. These details support operating room inventory approval, distributor onboarding, and institutional ENT tray purchasing.
How does the pivot and ring-handle mechanism work during surgery?
The pivot transfers ring-handle compression into closing movement at the distal circular cup. The surgeon positions the cup against the selected tissue margin under endoscopic visualization before closing the handle. This produces a controlled bite through mucosa, polypoid tissue, scarred margin, or thin residual tissue. The ring handles stabilize the hand during repeated opening and closing inside the nasal corridor. Stammberger Circular Punches use this mechanism to keep the cutting action focused at the distal tip. The straight shaft supports direct advancement toward the target without broad movement around the nasal entry.
Are Stammberger Circular Punches suitable for hospital reprocessing and distributor supply?
Stammberger Circular Punches are reusable and designed for standard surgical instrument sterilization workflows. Sterile processing teams can clean the cup jaw, shaft, pivot, and handles before autoclave sterilization according to facility protocol. German stainless steel construction supports repeated use in ENT operating room trays. MOQ of 1 piece allows hospitals and clinics to replace a single instrument as needed. OEM availability supports distributor-managed supply programs and institutional sourcing. The 1-year warranty with return and replacement service gives procurement teams clear commercial terms for inventory control.
