Precision Deep Within, Confidence Beyond Limits
SanAgile SASDL
When a surgery takes you deep into tight anatomical spaces, right up against vital organs and complex vascular structures, precision isn’t just a preference—it’s everything.
For surgeons in Gastrointestinal, Urological, Thoracic, and Gynecological fields, restricted deep-space visibility and hard-to-reach lesions have long been a frustrating challenge.
Introducing the SanAgile SASDL Ultra-Fine Extended Integrated Scalpel.
Engineered with a breakthrough design directly addressing clinical pain points, its extended, ultra-fine tip gives surgeons total freedom and finesse—even in the deepest, tightest pockets next to critical organs.
Breaking Through Deep-Space Limits
With a blade length boosted to 18.5 mm, the SASDL is tailor-made for confined spaces and high-stakes dissections.
In space-restricted regions like the deep pelvis or thoracic cavity, this extended tip delivers exceptional cutting and coagulation. Its refined geometry, combined with enhanced gripping force and non-stick performance, brings unprecedented safety and control to complex, long-duration procedures.
Expert consensus highlights that using an advanced ultrasonic scalpel effectively overcomes surgical space limitations, streamlining operating room workflows. During delicate maneuvers like lymph node dissections, keeping a safe distance between target tissue and vital structures is paramount. ¹
Featuring a curved, tapered tip that mimics the tactile feel of a mechanical dissector, the SASDL lets surgeons reach deep lesions while maintaining that crucial safety margin—drastically reducing instrument swaps mid-procedure.
Stronger Grip, Sharper Dissection
In the OR, how well an ultrasonic scalpel grips and dissects directly dictates surgical speed and safety. The SASDL brings a noticeable leap in performance here: clinical feedback confirms a significantly firmer grip with zero tissue slippage.
This upgrade comes down to two smart design refinements:
A Slimmer Profile: The sleek blade navigates tight spaces effortlessly for ultra-fine grasping and separation. When peeling away delicate tissue layers or dense adhesions, surgeons get incredibly crisp tactile feedback, lowering injury risks.
Optimized Blade Geometry: By fine-tuning the curvature and jaw mating surfaces, the SASDL maximizes tissue contact and fit, delivering exceptional friction and holding power. Even when handling high tissue tension, edema, or fatty infiltration deep in the surgical field, the tissue stays locked in place.
Whether it’s lymphadenectomy, fascial dissection, or vascular skeletonization, this "Grip Firmly, Dissect Precisely" capability keeps tissue traction rock-solid while cleanly dividing target structures.
Stronger Hemostasis, Faster Cutting
Need to seal blood vessels on the fly? The SASDL confidently handles up to 7 mm vessel sealing, making hemostasis smooth and stress-free.
At its core lies the RTTE II Algorithm. Building on the first generation's smart tissue sensing, RTTE II features a revamped architecture fueled by big data.
50,000 calculations per second
Over 1,000 parameter variations transmitted in real time
Trained on 100,000+ tissue fusion data points
This lightning-fast energy adjustment keeps device temperatures low and lateral thermal spread to a minimum—giving it a distinct edge over legacy international brands.
Lower Temperatures, Maximum Tissue Protection
Thermal injury is every surgeon’s top safety concern. Prolonged activation of ultrasonic energy can build up heat, risking delayed post-operative bleeding or accidental thermal damage to nearby nerves and blood vessels.
The SASDL’s RTTE II algorithm actively manages heat by monitoring tissue states in real time. By keeping blade temperatures in check, it drastically reduces lateral thermal spread, shielding surrounding vital structures. As a bonus, this smart heat management extends pad lifespan for reliable performance throughout long surgeries.
Plug-and-Play Integration
Forget tedious assembly. The all-in-one integrated transducer and scalpel design offers true plug-and-play simplicity. This significantly cuts pre-op setup time, boosts OR turnover efficiency, and simplifies nurse workflows.
To date, Saints Sages energy products have been successfully used in hundreds of thousands of surgeries across the globe. Throughout 2025–2026, Saints Sages showcased its full-series portfolio on global stages including MEDICA, CMEF, and Hospitalar, earning high acclaim from international partners.
Beyond Length: The Mastery of Micro-Precision
The Saints Sages SASDL Ultra-Fine Extended Integrated Scalpel isn't just longer—it's smarter:
18.5 mm extended tip to conquer deep-space anatomical limits
Slender, precision design for effortless grasping and separation
RTTE II smart algorithm protecting every millimeter of delicate tissue
Length gives you the reach; precision gives you the power. From Shanghai to the world stage, Saints Sages remains driven by clinical needs and technological innovation—ensuring every cut is clean and every seal is secure.
When surgery moves into deep waters, SASDL is the partner you can trust. Precision deep within, confidence beyond limits.
