Mako 112340 Pelvic Checkpoint Driver 7-1/4"

• Model: 112340 Mako
• Overall Length: 7-1/4 inches

These surgical instruments have been previously used and show visible signs of wear consistent with their prior usage. Despite these signs, they remain in a usable condition, suitable for continued medical procedures.

The Mako Model 112340 Pelvic Checkpoint Driver is a precision surgical instrument designed to engage and remove pelvic checkpoint pins used during Stryker Mako SmartRobotics™ hip and knee arthroplasty procedures. These checkpoint pins serve as critical fiducial markers that anchor and register pelvic anatomy to the robotic system. The driver is sized at approximately 7¼ inches (≈ 18 cm), enabling reliable reach and manipulation within the surgical field for cocking or withdrawing these pins safely.

Engineered from high‑grade stainless steel and compatible with sterilization processes used for Mako instruments, the 112340 driver provides a stable, ergonomic interface for handling the delicate checkpoint hardware. Its features, as referenced in Stryker’s instrument cleaning guide, include a robust handle and shaft attached to a tip precisely fit to the checkpoint pin head design. The driver is labeled specifically for pelvic checkpoints, distinguishing it from femoral or tibial checkpoint driver variants used in Mako joint replacement workflows.

Clinically, this driver plays a vital role just before final system shutdown during arthroplasty. Surgeons are instructed to remove pelvic (and femoral/tibial) checkpoint pins using the designated driver before completing the case and selecting the “Archive and Exit” function on the Mako console to avoid registration errors or system errors. Proper use of the 112340 driver ensures seamless detachment of the pelvic checkpoint and contributes to system accuracy and safety in robotic-assisted orthopedic procedures.
