How far can the best prosthetic hands go today?
Unfortunately, friends with hand amputations are especially envious of friends with leg amputations. Even many salespeople from prosthetic companies don’t pay much attention to customers with hand amputations, because customers with hand amputations have few options for installing prostheses, and customer satisfaction is very low.
Our hands have too many functions, and hand prostheses cannot compensate for the lost functions of the hands.
The best functional prosthesis is, of course, the bionic smart hand
The domestic bionic smart hand market has been occupied by foreign brands until now (2020), but a very cost-effective bionic smart hand has also appeared in China. I personally predict that this phone will become a strong competitor for foreign brands in the Chinese market.
Below I will mainly talk about the functions of influential foreign brands of bionic smart hands in our country in detail, so that the subject can have a better understanding (in order not to advertise the brand, I will use letters instead of the brand name, and I will code the brand logo).
First, Brand A comes from Germany (I won’t go into detail about who acquired whom)
The official description of this bionic hand has 14 different holding modes and gesture positions, trying to complete almost everything you need to do throughout the day: such as eating, carrying bags, opening doors, turning on lights, and typing. Independent motors on each finger allow for natural, coordinated hand movement and holding. This hand is available in three sizes, with a variety of wrist options to suit individual needs.
In fact, in summary, it can have the following six functions
1. Grasp
Can grasp round or cylindrical objects. For example, a ball or a piece of fruit, you can also hold a bottle or a door handle at home, which has a strong grip.
2. pinch
It can pinch thin and delicate objects, and it can also grasp keys, etc.
3. Mention
Hook grip feature allows carrying shopping bags or briefcases. It can bear 45kg in a stationary state.
4. Clamp
It can clamp thin objects or toothbrushes.
5. Trust
Can hold the bowl.
6. Press key
Remote control
Click on the keyboard
car keys.
The market price ranges from 260,000 to 600,000
Second, Brand B comes from Iceland (I won’t go into detail about who acquired whom)
Official description: A multi-jointed prosthetic hand with five independently powered fingers and a manually rotating thumb.
12 different automatic grip options available. Available in 4 sizes extra small, small, medium and large.
The functions are similar to those of product A and will not be described further.
But what impressed me most about this product’s hand is that it can be worn by people with missing fingers, and it is the best bionic smart hand on the market that can be worn by patients with missing fingers.
It can be tailored to fit different fingers that are missing.
The market price ranges from 300,000 to 600,000.

Let’s talk about a domestic bionic smart hand. As mentioned earlier, this hand may become a potential stock for smart prosthetics in the future. Its good sales do not necessarily mean that it is technically better than the previous two models, but that its price/performance ratio has a great advantage in China. It can basically implement the functions that foreign brands can achieve.
The official description of this hand is that it has 10 movable joints and 6 driving degrees of freedom, which can realize the independent movement of 5 fingers and the collaborative operation between fingers to meet the 23 common gestures required for daily use of upper limb amputees, and achieve free conversion between gestures.
The market price ranges from 100,000 to 150,000.
