TrenGuard 600 Hybrid with Integrated Wedge in Steep Trendelenburg with high-BMI patient

Physics. It's how TrenGuard® works.

"An object at rest tends to remain at rest unless an external force acts upon it." -Newton

TrenGuard's rigid support frame is fixed to the OR table accessory rails with wide-based rail clamps. 

Soft foam components, anchored to the frame, secure the patient while in Trendelenburg position.

Speed Bump bolster supports patient

The patented cervical notch bolster, in direct contact with the trapezius muscle, safely supports the body mass while patient is in Trendelenburg position.


A paper by surgeon and anesthesiologist, Dr. Hewer, describes this unique patient positioning restraint technique and explains how it also eliminates the risk of brachial plexus neuropathy.

Performance Specifications
TrenGuard Components on TrenGuard Frame
