Every syringe you’ve ever used works the same way. Push a plunger with your thumb. Hope your hand stays steady.
The first fundamental syringe redesign in 170 years. An index-finger trigger mechanism that gives physicians measurably better needle stability — peer-reviewed, published, and patented through 2040+.
Your index finger is your most dexterous digit. Ours is the first syringe that uses it. The trigger mechanism replaces the thumb-plunger action with a controlled squeeze — the same motion surgeons already trust for fine instruments.
20.9% better needle stability versus a standard thumb-plunger syringe (p=0.04). That’s a 0.97mm reduction in forward-retraction needle movement during injection. When the target tissue is measured in fractions of a millimeter, less movement matters.
DeLuna et al., Clinical Ophthalmology, 2019. Peer-reviewed.
No second hand needed to stabilize, retract, or adjust. The physician holds the syringe, controls the needle, and delivers the injection — all with one hand. The other hand stays free for tissue manipulation, ultrasound guidance, or patient stabilization.
Standard luer-lock hub. Works with existing needles, cannulas, and consumables. Nothing new to stock. Nothing new to learn, except how much steadier your hand feels.
Side by side, the difference is visible.
A standard syringe requires the thumb to travel the full length of the barrel. That motion transfers directly to the needle tip — forward push, then retraction overshoot. Every injection is a small negotiation between force and control.
The Precision Syringe isolates the delivery force from the needle. The index-finger trigger moves fluid without moving the tip. The result: 0.97mm less needle movement per injection, measured and published.
How the Suh Precision Syringe Works
Intravitreal injections demand sub-millimeter needle placement in a space where 2mm determines success or failure. The infant pars plana is roughly 2mm. The subretinal space is less than 250 microns. In the peer-reviewed study, the experienced ophthalmologist showed the greatest improvement in needle stability with the Precision Syringe. This is where better needle stability matters most — and where it was measured first. Learn more
Filler placement and neurotoxin delivery depend on steady, controlled injection at precise depths. Practitioners perform dozens of injections per day, often freehand, often in tissue where a millimeter of drift changes the result. A trigger mechanism that reduces needle movement means more consistent placement across a full day of procedures — first patient to last. Learn More
Animal patients don’t hold still. Research protocols don’t tolerate variability. Whether it’s a retrobulbar block in a 4-kilogram cat or a micro-injection in a preclinical model, the same physics apply: less needle movement during delivery means a more controlled injection. The universal luer-lock fits existing lab and clinical setups without modification.Learn more.
