Q1：Who is this bionic prosthetic hand suitable for?
A：This myoelectric prosthetic hand fits upper limb amputees, including wrist disarticulation, below-elbow amputation and partial hand loss. It is widely used for daily life, light industrial operation and rehabilitation training, suitable for adults aged 16–65 with residual muscle signal.
Q2：How does the mechanical prosthetic hand control movement?
A：It adopts myoelectric sensor control. Two high-sensitivity electrodes attach to the residual forearm muscles. When you contract/relax muscles, the sensor captures bioelectrical signals to trigger opening, closing, grasping and rotating of the prosthetic fingers, just like controlling a real hand.
Q3：How many grasping modes does the prosthetic hand support?
A：It supports 6 common functional grips: power grip for holding bottles/cups, precision grip for picking up coins/pens, lateral grip for carrying bags, hook grip for pulling objects, thumb opposition grip and rest mode. It can switch modes with simple muscle signal adjustment.
Q4：What’s the weight and battery life of the bionic hand?
A：The main hand weighs only 280g, no extra burden on residual limbs. The built-in lithium battery supports 8–12 hours of continuous daily use; full charging takes 2 hours, and it comes with a portable USB charging kit for outdoor use.
Q5：Is the prosthetic hand waterproof and wear-resistant?
A：The finger shell uses high-strength medical-grade silicone, anti-slip and wear-resistant. The whole hand reaches IP54 daily waterproof standard, resisting splashing water, sweat and rain. It cannot be soaked in water for long periods (bathing/swimming not allowed).
Q6：Can I wear daily gloves and do simple housework with it?
A：Yes. The finger outline matches real human hand size, compatible with standard thin cotton gloves. It can finish daily tasks: holding tableware, typing, carrying shopping bags, opening doors and picking up small items. Heavy pulling or high-load work is not recommended.
Q7：How long is the service life of the prosthetic hand?
A：The core motor and sensor parts have a 5-year service life; the silicone finger cover is a consumable part, which can be replaced every 1–2 years according to wear conditions. We provide separate replacement silicone shells for after-sales.
Q8：Do you provide professional installation and fitting service?
A：We supply full fitting guide videos and professional measurement templates. Cooperated rehabilitation clinics in most countries can complete residual limb socket fitting. We offer one-to-one remote technical guidance for all buyers.
Q9：Is this prosthetic hand certified for medical export?
A：Our bionic prosthetic hand has passed CE medical device certification, ISO13485 quality system certification, meets EU and North American rehabilitation medical standards, and supports customs clearance for medical equipment export.
Q10：What’s your MOQ and delivery time?
A：MOQ is 1 unit for sample testing; bulk orders over 10 units enjoy wholesale discount. Stock items deliver within 3–7 working days, customized socket molds take 10–15 days production cycle.
Q11：Does the product come with after-sales warranty?
A：We provide 2-year global warranty for core electronic components (motors, sensors, circuit boards). Damage caused by improper disassembly, soaking or man-made collision is not covered by warranty, but we offer low-cost spare parts replacement service.
Q12：Can children use this mechanical prosthetic hand?
A：This standard model is designed for adults. We have a mini-sized pediatric prosthetic hand for teenagers under 16, with lighter weight and smaller finger size, you can contact us for separate parameter introduction.
Q13：Can the prosthetic fingers rotate freely?
A：The thumb supports 360° passive rotation, and each independent finger can flex and stretch separately to fit different grasping postures, restoring natural hand movement logic.
Q14：What material is the prosthetic hand made of?
A：Internal drive components: aluminum alloy lightweight frame + silent micro servo motors; outer skin: medical soft silicone, skin-tone optional (natural light skin, medium skin, dark skin).
Q15：How to clean and maintain the prosthetic hand?
A：Wipe silicone surface with alcohol-free wet wipes daily to remove sweat and dust. Do not immerse the hand in water. Charge the battery every 3 days if not in use for a long time to avoid battery aging.
