Abstract
The invention provides an artificial upper limb arm tube which comprises an upper arm tube body (1) and a lower arm tube body (2). The artificial upper limb arm tube is characterized in that through the match between a stepped outer circle (3-1) of a cylindrical metal insert (3) of the upper arm tube body (1) and a cylindrical stepped round hole (2-2) of the lower arm tube body (2), and through a locking mechanism in the middle, the upper arm tube body (1) and the lower arm tube body (2) are connected into a whole, and the upper arm tube body (1) and the lower arm tube body (2) can carry out 360-degree circular motion relative to each other. According to the artificial upper limb arm tube, the upper arm tube body and the lower arm tube body are formed through injection molding, in the aspect of appearance, the artificial upper limb arm tube achieves the effect of the simulation human arm, and the production efficiency is also greatly improved; the stepped outer circle of the upper arm tube body with the metal insert is matched with the cylindrical stepped round hole of the lower arm tube body, and further through the intermediate locking mechanism, the upper arm tube body and the lower arm tube body are connected into a whole, and thus the upper arm tube body and the lower arm tube body can carry out 360-degree circular motion relative to each other.
Description
Technical field
The present invention relates to myoelectricity, Electronic control upper extremity prosthesis field, specifically refer to a kind of upper extremity prosthesis arm cylinder.
Background technology
Along with the development of society, the continuous generation of various industrial accident and the various natural disaster such as vehicle accident and earthquake, the continuous appearance of various people with disability, how to improve quality of life and the work quality of these people with disabilitys, especially the quality of life of deficiency of skeletal limb person on those is improved, be the responsibility of the whole society, the appearance of various artificial limb really gives people with disability and brings great convenience, and makes them also can carry out as the normal person living, works, learns.In upper limb, most realistic meaning is exactly have to close function and fetch doing evil through another person of object function, and elbow joint and carpal joint.
Along with the development of upper extremity prosthesis, in doing evil through another person, the representative also maximum production and application of most is that rope control is done evil through another person, Electronic control is done evil through another person and myoelectrically controlled hand.It is rely on merely rope to control action of doing evil through another person that rope control is done evil through another person, and is a kind of motion of Purely mechanical.And Electronic control is done evil through another person and myoelectrically controlled hand is doing evil through another person of relying on motor switch and electromyographic signal to control respectively.No matter be that rope control is done evil through another person, or myoelectricity and electrically powered hand they all need by arm cylinder come be connected with the deformed limb of patient, just can complete the function of artificial limb.The arm cylinder that current artificial limb industry uses is all generally adopt the method for evacuation to make, in the outward appearance or efficiency of arm cylinder, all have weak point.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of this invention is to provide a kind of bio-imitability good, the upper extremity prosthesis arm cylinder that production efficiency is high.
Technical scheme of the present invention is achieved in the following ways: a kind of upper extremity prosthesis arm cylinder, comprise: upper arm cylinder and underarm cylinder, described upper arm cylinder is the horn-like cylinder that two ends communicate, caliber size is different, its one end is and upper arm cylinder injection moulding all-in-one-piece cylindrical metal inserts, the side of the other end of upper arm cylinder has arc notch, arcuately there is the step plane of spill at breach edge, has two strip grooves at arc notch two medial surface, is provided with two step cutting pattern holes in groove; Described underarm cylinder is also the horn-like cylinder that two ends communicate, caliber size is different, and the profile of its one end is that cylindrical, one end medial surface has ladder circular hole; Other end profile is the elliptic arc I of human simulation arm shape, there is the elliptic arc II that a straight section, shape are identical with appearance inner side, it is characterized in that: described upper arm cylinder is matched by the ladder cylindrical of cylindrical metal inserts and the cylindrical ladder circular hole of underarm cylinder, centre makes upper arm cylinder and lower two-arm cylinder be connected by retaining mechanism again, mutually can make 360 degree of circular motion between upper arm cylinder 1 and underarm cylinder.
Described metal insert profile is for there being ladder cylindrical, and there is the cylinder of through hole centre, has counterbore in inside, cylinder two sides, its side counterbore is 90 degree of directions have four straight troughs and screwed hole, has two grooves at cylindrical outer surface.
Described upper arm cylinder and underarm cylinder all adopt injection molded.
The present invention, upper and lower arm cylinder adopts injection molded, human simulation arm effect can be reached in shape, and substantially increase production efficiency, match with the ladder cylindrical of the upper arm cylinder of metal insert and the cylindrical ladder circular hole of underarm cylinder, centre makes upper and lower two-arm cylinder be connected by retaining mechanism again, can make mutually to make 360 degree of circular motion between upper and lower arm cylinder.

Detailed description of the invention
Shown in Fig. 1, Fig. 2, upper extremity prosthesis arm cylinder of the present invention, comprises upper arm cylinder 1 and underarm cylinder 2.One end of upper arm cylinder 1 has metal insert 3 to be injected into a whole with it.
As shown in Figure 3, be upper arm cylinder axonometric chart of the present invention.Upper arm cylinder 1 is moulding, its profile is the horn-like cylinder that two ends communicate, caliber size is different, cylindrical metal inserts 3 is had to be injection molded into one on one end, arc notch 1-1 is had in other end cylindrical sides, arcuately there is sunk step plane 1-2 at breach edge, there are two strip groove 1-3 at arc notch two medial surface, in groove, have two step cutting pattern hole 1-4.
Shown in Fig. 4, Fig. 5, be metal insert front view of the present invention and left view.Described metal insert 3 profile is for there being ladder cylindrical 3-1, and there is the cylinder of through hole 3-2 centre, counterbore 3-3 is had in inside, cylinder two sides, its side counterbore is 90 degree of directions have four straight trough 3-4, its side counterbore plane there is screwed hole 3-5, has two groove 3-6 at cylindrical outer surface.
