Surgical Stapler Cartridge Holder

Name: Surgical Stapler Cartridge Holder | Stapler Reload Housing - Frigate
Price: 249.00 USD
Availability: InStock

The Surgical Stapler Cartridge Holder is engineered to resist structural deformation under actuation forces exceeding 100 N. Load-bearing ribs and filleted transitions distribute localized shear loads evenly, preventing failure at high-stress points. Material choices are optimized to deliver high yield strength with minimal mass, supporting thin-wall geometries without compromising holding performance during staple deployment.

Product Description

The Surgical Stapler Cartridge Holder maintains dimensional stability after repeated autoclave and ethylene oxide sterilization cycles. Material systems such as reinforced PEEK and surgical-grade stainless steel are selected based on low thermal expansion coefficients and long-term thermal aging resistance. The holder resists creep and thermal fatigue, ensuring mechanical consistency throughout the device lifecycle.

38–42 HRC (17-4PH), 32–36 HRC (Ti), 60–70 HRB (Al)

Concentricity Requirement

≤0.01mm TIR (Staple Alignment), ≤0.02mm (Body Runout)

Flatness & Parallelism

Flatness ≤0.03mm/m, Parallelism ≤0.02mm, Perpendicularity ≤0.015mm

Technical Advantages

The Surgical Stapler Cartridge Holder achieves tight geometric alignment with the staple cartridge through machined or molded features held within ±25 micron tolerance. Datum surfaces and locking planes ensure the cartridge seats orthogonally and concentrically, eliminating misalignment that could distort staple formation or compromise tissue capture efficiency.

The Surgical Stapler Cartridge Holder is validated for repeatable mechanical response over more than 500 loading cycles. Compliant locking features and elastic hinge zones maintain consistent contact force and deflection profiles across all use phases. Stiffness degradation and permanent deformation are mitigated by fatigue-optimized design and polymer stress relaxation modeling.

Industry Applications

Laparoscopic Bowel Resection

Supports controlled staple alignment in confined operative fields, maintaining precision during intestinal transection and anastomosis under limited visual feedback.

Thoracic Lung Lobectomy

Ensures stable cartridge retention during bronchial and vascular division, resisting mechanical shock and torsion in minimally invasive thoracic procedures.

Gastrointestinal Sleeve Gastrectomy

Maintains orthogonal cartridge orientation for uniform staple line formation on thick gastric walls during laparoscopic bariatric surgical procedures.

Colorectal Anastomosis

Provides rigid cartridge seating and consistent staple height control for secure tissue approximation in circular or linear end-to-end reconstructions.

Esophageal Resection

Enables precise cartridge ejection and locking under deep cavity access conditions where angular misalignment affects staple formation reliability.

Gynecologic Hysterectomy

Supports uterine artery ligation and endometrial detachment with reliable cartridge retention under multi-directional actuation in tight pelvic spaces.

Biocompatibility and Particulate Control

The Surgical Stapler Cartridge Holder uses materials fully compliant with ISO 10993 and USP Class VI, including surface treatments that meet submicron roughness specifications. Friction interfaces are engineered to minimize particle shedding during actuation, and non-leaching polymers are employed to reduce contamination risk in sterile fields.

The Surgical Stapler Cartridge Holder incorporates compliance zones and float mechanisms to counteract mismatched thermal expansion between the cartridge body and adjacent structural components. This enables precise interface retention without overstressing polymer-metal joints, maintaining alignment across thermal excursions from ambient to sterilization conditions.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure zero-lash cartridge locking in its stapler cartridge holder design?

Frigate uses interference-fit geometries and multi-plane locking tabs to eliminate backlash during cartridge engagement. Each holder undergoes CMM-based verification to confirm contact uniformity across all seating surfaces. Finite element simulations are used to model dynamic engagement under actuation loads. This ensures stable cartridge positioning with no rotational or axial play.

What materials does Frigate use to prevent structural fatigue under cyclic surgical loads?

Frigate selects fatigue-rated PEEK composites and ASTM F138 stainless alloys with verified S-N curve behavior beyond 10⁶ cycles. Material selection is based on both thermal endurance and elasticity retention. Internal stress concentrations are minimized through radiused features and uniform wall thickness. The final design resists mechanical fatigue across repeated cartridge insertions and firings.

How does Frigate validate cartridge holder compatibility with different stapler shaft geometries?

Frigate applies GD&T-based interface mapping across various OEM shaft profiles using parametric CAD fit testing. Compliance zones are tuned to accommodate shaft tolerances while maintaining insertion force limits. Each production lot includes a mechanical fit audit against multiple shaft types. This ensures universal compatibility without overstressing delicate alignment features.

What methods does Frigate use to control surface contamination risk during molding of the cartridge holder?

Frigate runs all molding operations in ISO Class 8 cleanroom environments using medical-grade tooling and low-shear injection parameters. Gate design and venting prevent micro-burns or flow lines that contribute to particulate release. Molded parts undergo ultrasonic cleaning and non-volatile residue testing. This keeps surface contaminants within surgical-grade tolerances for implant-adjacent components.

How does Frigate achieve dimensional consistency in high-volume runs of surgical stapler cartridge holders?

Frigate employs closed-loop process controls and real-time SPC on all critical dimensions during injection molding and secondary machining. Tool wear is tracked with in-process deviation thresholds not exceeding ±10 microns. Automated vision systems inspect every unit for dimensional outliers and flash. This ensures uniform fit and mechanical performance at production scales exceeding 100,000 units.
