Powered Endoscopic Linear Cutter Stapler System
Engineered for zero-misfire reliability and consistent B-form staple shaping—eliminating tissue shear and power failure in complex laparoscopic resections.
Clinical Safety Focus: Factory-tested single-use power unit guarantees continuous motor output without mid-procedure voltage drops.
Triple Emergency Overrides: Built-in mechanical override lever ensures immediate jaw release and safe disengagement under any power contingency.
Smooth Cut Technology: Dual-metal precision blade maintains ≤0.80N cutting force for clean, fray-free tissue margins.
ENGINEERING & CLINICAL SAFETY
Precision Engineering Built for Clinical Certainty
Addressing mid-procedure power anxiety, tissue shear, and distal jaw splaying through advanced mechanical design.
Constant Power Architecture
Single-Use Pre-Installed Battery: Ready to use with steady voltage output throughout the procedure. Eliminates hospital charging maintenance, cross-contamination, and mid-operation battery failure.
Fail-Safe
Protection
Manual Emergency Override: Features an independent mechanical override lever that instantly unlocks the jaws and disengages delicate tissue in any extreme mechanical or electrical contingency.
Precision Cutting
System
Dual-Metal Blade Technology: Delivers ultra-low ≤0.80N cutting force to preserve clean, fray-free tissue margins while minimizing intraoperative bleeding and trauma.
50° ARTICULATION & RIGID FRAME
50° Max Articulation with Anti-Splay Frame Architecture
Deep Cavity Access: Features 50° (±10°) bilateral articulation, effortlessly reaching deep thoracic and pelvic dead zones.
17-4PH Stainless Steel Frame: Precision-machined metal housing prevents distal jaw deflection (“tip flare”) under extreme tissue loads.
Tactile Steering: Manual articulation retains intuitive resistance feedback, while motorized drive handles tissue transection.
High-Torque Joint Lock
Eliminates angle slippage in deep, high-resistance tissue fields.
Uniform B-Form Closure
Prevents end-to-end tissue pinching and distal staple line failure.
SAFETY & EMERGENCY OVERRIDE
Triple-Layer Retraction & Pure Mechanical Emergency Override
Automated & Motorized Return: Once full tissue transection is completed, the Powered Endoscopic Linear Cutter Stapler automatically resets its knife blade. An integrated electronic return switch enables mid-cycle retraction if full firing is unnecessary.
Pure Mechanical Emergency Override: In rare intraoperative scenarios—such as battery exhaustion or system error where a powered endoscopic stapler jammed during procedure manual override becomes critical—surgeons can flip the top safety latch. The completely independent mechanical lever manually retracts the knife blade without electrical power, preventing organ trapment.
Visual Location Window: A built-in transparent inspection portal provides clear optical confirmation of the knife position before jaw release, lowering procedure risk in complex dissections.

Mechanical Override Safety
METALLURGY & BIOCOMPATIBILITY
Implant-Grade TA2G Titanium Staples & Dual-Metal Blade
Microvascular Perfusion: Six staggered rows of B-form staples maintain capillary blood flow in interstitial tissue gaps, significantly lowering tissue ischemia and necrosis risks.
Dual-Metal Edge: High-carbon martensitic stainless steel fused with a spring-steel backbone ensures sharp, burr-free cuts with fresh-blade performance on every firing.
1.5–3.0T MRI Safe: Non-ferromagnetic TA2G pure titanium delivers optimal biocompatibility, minimizing artifact interference during post-operative MRI imaging
Burst Pressure
Exceeds physiological pressure limits for leak-free, reliable suture line integrity.
Tensile Strength
TA2G implant-grade titanium ensures secure tissue approximation without staple deformation.
UNIVERSAL PORT FIT
Seamless 12mm Trocar Compatibility for Streamlined Surgical Workflows
Designed with precise outer diameter control, the endoscopic linear cutter shaft slides smoothly through standard 12mm laparoscopic trocar sleeves. This precise fit eliminates intraoperative tissue friction, minimizes instrument drag, and simplifies operating room supply chain requirements.
- Standardized Shaft Geometry - Compatible with major universal trocar systems.
- Smooth Insertion & Pass-through - Reduced friction coefficient for enhanced surgeon tactile feedback.
- Cost-Efficient Compatibility - Fits existing laparoscopic infrastructure without extra proprietary cannulas.
TOTAL COST OF OWNERSHIP (TCO) OPTIMIZATION
Break the Monopoly: Open Compatibility vs. Proprietary Lock-in
Evaluating the financial impact of surgical supply chain choices. Transitioning to universal laparoscopic compatibility significantly lowers inventory capital requirements and operational waste.
TRADITIONAL BUNDLED MODEL
Proprietary Monopolistic Ecosystem
- High Equipment Capital: Requires purchasing dedicated proprietary trocars and handles.
- Heavy Inventory Overhead: High safety stock reserves required across multiple hospital wards.
- Inflexible Procurement: Vendor lock-in reduces supply chain bargaining power.
- Increased Waste: Incompatible reloads create high turnover and expiry losses.
JIAYU UNIVERSAL MODEL (RECOMMENDED)
Open Standard & TCO Efficient
- Up to 30-40% Cost Savings: Directly lowers per-procedure consumable expenditure.
- Universal Compatibility: Seamlessly integrates with existing standard 12mm trocars.
- Streamlined SKU Inventory: Reduced inventory holding costs and risk of stock expiration.
- Transparent Supply Chain: Direct OEM/distributor model ensures predictable procurement costs.
COLOR-CODED RELOAD SYSTEM
Standardized Color-Coded Reloads for Precision Tissue Adaptability
Engineered for effortless intraoperative identification and optimal tissue compression. Each reload features a 6-row staggered TA2G titanium staple configuration to ensure leak-resistant staple line security.
