Precision Surgical Repair You Can Trust
A focused team dedicated exclusively to surgical instrument repair, held to ISO 9001:2015 and OEM-level standards on every unit.
Precision Engineering. Focused Expertise.
SIRLab, LLC was founded on a simple premise: surgical equipment repair deserves the same precision and accountability as the procedures it supports. Healthcare facilities, from community hospitals to major academic medical centers, need a repair partner they can trust completely.
That’s why SIRLab focuses exclusively on surgical instruments and patient positioning systems. Rather than attempting to fix everything, we master the critical equipment we know best.
Our specialized focus on Allen Yellofin® stirrups is backed by years of hands-on technical experience across thousands of successful repairs. That depth of real-world exposure allows us to maintain a full, in-stock parts inventory for every generation and model, supporting some of the fastest turnaround times in the industry.
When the OEM can’t help, SIRLab can. Our in-house machine shop capabilities and deep engineering knowledge allow us to fabricate components and solutions that even original manufacturers sometimes decline.
