General Exoskeleton Tips for Distributors
Always have your exoskeleton with you when calling on surgeons. Doctors can quickly try on an exoskeleton in under 5 minutes, so demos can happen unexpectedly and frequently. Use an exoskeleton transport bag (available from Hapo) for professional and easy transportation.
Proper doffing (removing) of the exoskeleton is as crucial as donning it. Correct removal makes future donning simpler, so store it in the same manner you put it on. (Link to video)
Arm pad tip: Leave the forearm strap connected to the magnetic fidlock when removing the device. Loosen the bicep strap completely, pull the red tab on the fidlock to detach, slide your arm out while holding the fidlock, and reattach it to the buckle on the shoulder strap.
To don the device again, slide your arm through the connected forearm pad, secure the bicep fidlock around the pad, and tighten until there is no movement when vigorously moving your arms. (link)
Order of donning/doffing: Put the exoskeleton on from bottom to top (waist, chest, arms) and remove it in reverse order (arms, chest, waist).
Pre-demo scheduling: Request 10–15 minutes of undivided attention from the surgeon before entering the OR. During this initial fitting, explain each adjustment clearly (what, how, why) and ask the surgeon to simulate their surgical movements. Questions like "How does it feel?", "Do you have full range of motion?" and "Any discomfort?" are essential to ensure proper fit.
Fitting goals:
Ensure the surgeon understands and anticipates the device's behavior.
Initiate training to turn surgeons into proficient exoskeleton users. Frequent and consistent usage yields significant long-term benefits, much like regular gym attendance. Having a surgical assistant present ensures additional support if the surgeon forgets fitting details.
Mechanical settings (Hapo Front):
Waist setting (numbers 1–5):
Setting 5 (closer to the hip): Arms naturally sit farther from the body, providing more resistance for smaller surgeons.
Setting 1 (closer to the spine): Keeps arms closest to the body—ideal for facial or microsurgeries.
Note: The wider the spring setting, the more pronounced the profile over the shoulders, potentially affecting comfort under scrubs. Ensure surgical gowns accommodate the exoskeleton comfortably.
Spring height setting (letters A–H):
Setting A (lowest): May cause the spring to rub against the shoulders or scapula. Monitor for comfort.
Setting H (highest): Exaggerates spring profile significantly. Adjust only as high as necessary.
Fabric fitting:
Backplate: Optimal positioning has the bottom of the backplate resting atop the tailbone, with the waist belt at or slightly above the hips. Adjust height with two velcro straps above the backplate.
Shoulder straps: Adjust snugness using velcro straps under each armpit. Ensure no significant gaps between the fabric and the surgeon to maintain stability during procedures.
Common Questions and Objections:
“Why is this device so cheap?”
We prefer "accessible." We aim to prevent early retirement due to MSDs, allowing you more quality time with family.
“Why is this device so expensive?”
Significant time and expertise go into our ergonomic exoskeletons. The investment often pays off through extended careers and easier, more productive surgical days.
“Why only 4–6 lbs of assistance?”
Through extensive testing, we've found that around 4 lbs provides optimal precision without fighting excessive resistance, reducing muscle activity by 33% in biceps and 16–18% in shoulders. (Link to study)
“Difference between 4lb and 6lb springs?”
The 6lb spring offers increased assistance. If uncertain, consider the weight of objects the surgeon typically handles. Springs are interchangeable between arms.
“What are the springs made of, and their lifespan?”
Springs are durable composite fiberglass, typically lasting up to 5 years of regular (40 hours/week) use before support diminishes.
“Can I wear Hapo Front and Hapo Back simultaneously?”
No, their waist and shoulder straps physically overlap, making simultaneous use impractical.
“Why doesn't the device support every body part?”
Early full-body exoskeleton designs proved cumbersome and heavy. Our lightweight, low-profile exoskeletons provide precise support and freedom of motion essential for surgery.

Quick Facts:
Hapo Front Exoskeleton:
Assists shoulder and arm strain during waist-to-eye-level tasks.
Provides 4 or 6.5 lbs assistance per arm.
Reduces biceps strain up to 33% and deltoids strain by 18%.
Lightweight (<3 lbs), passive device (no motors/batteries).
Hapo Back Exoskeleton:
Assists lower back strain during lifting tasks or prolonged awkward postures.
Surgical Applications for Hapo Front:
Ideal for repetitive arm movements (e.g., liposuction).
Beneficial for prolonged static arm positions (e.g., endoscopic procedures, breast augmentations).
