OHAN
Precision Rodent Surgery Instruments, Born at the Bench
OHAN instruments are not sourced from a catalog. They were designed by a physician-researcher who spent years performing rodent microsurgery and contract research — and got frustrated with tools that weren't built for the realities of small animal work. Every OHAN product solves a specific problem that generic instruments fail to address.
Designed by a surgeon. Built for researchers who actually operate.
BMR Supply's founder came from clinical medicine before transitioning into full-time university research. For years, he performed mouse and rat microsurgery as part of preclinical research contracts — and encountered the same problems most researchers do: intubation kits that weren't sized for rodents, fiber optics that didn't illuminate the airway adequately, and instruments engineered for human surgery, not a 25-gram mouse.
OHAN was the answer. Each instrument in the line was developed to address a specific procedural gap identified through hands-on rodent surgery experience. The result is a focused, precision instrument line available exclusively through BMR Supply — not adapted from something else, but designed from the ground up for the way small animal surgery is actually performed.
Clinician-designed
Every dimension, material, and geometry informed by real surgical experience — not engineering theory.
Species-specific sizing
Calibrated for mouse and rat anatomy — not scaled down from human instruments.
Exclusively at BMR Supply
OHAN instruments are not available through distributors, Amazon, or any other supplier.
Every instrument. One exclusive source.
Eight precision instruments, each designed to solve a specific problem in rodent surgery and intubation.
Complete orotracheal intubation kit calibrated for mouse anatomy. Includes all components required for reliable, low-trauma airway management in mouse survival surgery and anesthesia protocols.
View product
Full intubation system sized for rat airway management. Designed for consistent, reproducible orotracheal access in rat surgical models — from acute studies to survival surgery protocols requiring mechanical ventilation.
View product
Combined kit covering both mouse and rat intubation in a single purchase. Ideal for multi-species research programs or facilities transitioning between rodent models. All components included for both species.
View product
Purpose-built laryngoscope for direct visualization of the rodent glottis during orotracheal intubation. Blade geometry and dimensions optimized for mouse and rat laryngeal anatomy, enabling confident tube placement in fewer attempts.
View product
High-intensity fiber optic illumination unit designed for the OHAN intubation system. Provides consistent, shadow-free lighting at the rodent glottis — the critical factor in successful first-pass intubation in small animal models.
View product
Precision instrument for passing vessel loops and sutures around small blood vessels in rodent microsurgery. Critical for vascular isolation, temporary occlusion, and anastomosis preparation in mouse and rat vascular surgical models.
View product
Replacement and spare fiber optic cable sized for mouse intubation procedures. Compatible with the OHAN fiber optic light source. Allows independent replacement of the cable component without replacing the full illumination system.
View product
Replacement fiber optic cable sized for rat intubation procedures. Compatible with the OHAN fiber optic light unit. Ensures continued reliable illumination for rat airway visualization when the cable requires replacement after extended use.
View productBuilt to solve the problems you've already encountered.
First-pass intubation success
The laryngoscope and fiber optic system are designed together to maximize glottic visualization, reducing failed attempts and procedural stress on the animal.
Species-accurate dimensions
Mouse kits and rat kits are not the same instrument in a different box — they are independently sized for each species' specific airway geometry.
Trusted by research teams
Used in academic medical centers, university research laboratories, and contract research organizations performing survival rodent surgery protocols.

OHAN Rodent Surgery Instruments — Exclusive to BMR Supply
OHAN is a proprietary line of precision rodent surgery instruments developed and sold exclusively by BMR Supply. The OHAN instrument line was created to address the specific procedural requirements of small animal surgery — particularly orotracheal intubation, fiber optic airway illumination, and vascular microsurgery in mouse and rat models. All OHAN instruments are developed from hands-on preclinical surgery experience and are not available through any other supplier or distributor.
Rodent Intubation Systems for Mouse and Rat Models
The OHAN intubation system covers three kit configurations: a mouse-specific intubation kit, a rat-specific intubation system kit, and a combined mouse and rat kit for multi-species research programs. Each kit is designed as a complete, ready-to-use system — including the species-appropriate laryngoscope, fiber optic illumination cable, and endotracheal components. Separate fiber optic cables for mouse and rat intubation are available as replacement or spare components.
OHAN Rodent Laryngoscope
The OHAN rodent laryngoscope features blade geometry and dimensions developed specifically for the rodent larynx, enabling direct visualization of the glottis during orotracheal intubation. Used in conjunction with the OHAN fiber optic light, it provides the illumination and visualization required for reliable first-pass tube placement — a critical factor in reducing procedural time and anesthetic risk in small animal surgery.
OHAN Fiber Optic Light and Cables
The OHAN fiber optic light source delivers high-intensity, focused illumination to the rodent airway during intubation procedures. Compatible fiber cables are available in mouse-specific and rat-specific configurations, sized for the anatomical working distances of each species. The modular design allows independent cable replacement without replacing the full illumination unit.
Micro-Vascular Suture Hook and Vessel Loop Passer
The OHAN micro-vascular suture hook and vessel loop passer is a precision instrument for rodent vascular microsurgery. It is designed for controlled passage of suture material and vessel loops around small blood vessels — an essential maneuver in femoral artery cannulation, renal artery isolation, mesenteric vessel work, and carotid artery surgery in mouse and rat models. The instrument geometry is calibrated for the vessel diameters and tissue depths encountered in small animal vascular procedures.
