Description
Technical field
The invention belongs to technical field of medical instruments, especially relate to one and utilize bands transmission and by three D
The artificial limb that printing technique makes.
Background technology
The democratic meeting of people is caused the biggest puzzlement by physical disabilities, and the artificial limb market demand that I crosses at present is extensive,
But embarrassing, the prosthetic product quantity of China, kind are rare, and performance is single, lack innovation in time,
And there is bigger gap between advanced international standard.China's prosthetic product market is mainly captured by overseas enterprise,
But imported product often price is high, and the disabled people scholar of China 75% is distributed in vast cities and towns and rural area.
Owing in amputee, major part is the population below the poverty line, therefore the popularity rate of artificial limb is the highest, it is estimated that there are about 70%
People not yet installs artificial limb；And upper extremity prosthesis in the market mainly includes for ornamental Simulated hand, rope control
Formula Simulated hand and myoelectricity formula Simulated hand, wherein, although ornamental Simulated hand is more attractive in appearance, but close without finger
Joint, without grip perception, controls without grip, does not also have practicality, and expensive；Wire-control type Simulated hand
Can only passive opening and closing and it needs to certain use training；Myoelectricity formula Simulated hand, it is more difficult that grip controls,
Energy actively opening and closing, needs certain exercise, but price is at 3 ten thousand to ten ten thousand yuan；These upper extremity prosthesises are equal
There is different problems.Therefore need badly in the middle of prior art and want a kind of novel technical scheme to ask to solve this
Topic.
Summary of the invention
The technical problem to be solved is: provide a kind of bands transmission three D to print artificial limb arm, logical
Cross three D printing techniques and obtain artificial limb simple structure, dependable performance, it is simple to grasping, easy to use, price is relatively
Low, can commonly use at home.
A kind of bands transmission three D prints artificial limb arm, it is characterized in that: include upper arm shell, underarm shell,
Palm shell, elastic thread, draught line, finger-joint and finger front end, described upper arm shell is provided with
Rope fastening hole and fixing bandage, upper arm shell is flexibly connected by concentric circular screw with underarm shell；Described
Being provided with through wires hole and two fixing bandages on underarm shell, underarm shell and palm shell are by concentric circular spiral shell
Silk is flexibly connected；Described palm shell be internally provided with five troughs, the side of palm shell is provided with
Thumb joint, the side of described thumb joint is connected with thumb front end by concentric circular screw；Outside palm
The front end of shell is provided with four finger-joints；The bottom of described each finger-joint respectively with each finger front end
It is flexibly connected by concentric circular screw；
The fingertip location of described four finger front ends and thumb front end is provided with the fixing end of elastic thread, described bullet
The line of force is set to five, and one end of every elastic thread is each attached on the fixing end of elastic thread, every elastic thread
The other end is each passed through on palm shell the trough being correspondingly arranged, and is fixed on the stomidium of the trough port of export
On；
Described draught line is set to five, and one end of a draught line is arranged on the elastic thread of thumb front end and fixes
On end, one end of four draught lines of residue is separately positioned on four known front ends the fixing end of the elastic thread arranged；
Article five, the other end of draught line is each passed through the rope fastening hole entering upper arm shell after trough enters through wires hole
Interior fixing.
Described upper arm shell, underarm shell and palm shell are all printed by three D printers and obtain.
Two the fixing bandages arranged on the fixing bandage arranged on described upper arm shell and underarm shell are all and thumb
Articulations digitorum manus homonymy.
By above-mentioned design, the present invention can bring following beneficial effect: a kind of bands transmission three D beats
Print artificial limb arm, obtains artificial limb simple structure, dependable performance by three D printing techniques, it is simple to grasps, makes
With convenient, price is relatively low, can commonly use at home.The artificial limb arm obtained by three D printing techniques
Can realize all can be customized to different patients, and cheap；Upper arm shell, underarm shell, hands
All connected by concentric circular screw between palm shell and finger, can perfectly realize bending and grasp dynamic
Make, be that artificial limb use is more flexible.
