Description
Technical field
The present invention relates to a kind of is the structure of the artificial limb of representative with the artificial leg, particularly, relates to the structure of the parts of the deformed limb that will be installed to amputee (or people of similar use artificial limb).
Background technology
Artificial limb is when losing limbs, is used for replenishing the function of limbs of some people and the device of outward appearance.
To provide explanation, illustrate typical artificial leg.The amputee at first embeds the parts of acinacicate on the deformed limb, and with deformed limb in parts insert the receptive cavity of main body of artificial leg, finish the wearing of artificial leg.Provide the parts of acinacicate to be used to prevent that deformed limb is at the artificial leg internal friction at first.The performance that requires these parts to have the buffering effect and hang artificial leg subsequently.These parts have developed into liner.
Check the improved history of artificial leg, the spendable basis that is used for artificial leg is created at late period nineteen forties now.Before this, artificial leg is made by timber (Magnolia obovata etc.) or metal (mainly being aluminum).Deformed limb covers marsupial shape socks and inserts in the receptive cavity, and by using belt and shoulder belt to hang receptive cavity.This also is called the insert type artificial leg, and present considerable people still regularly uses it.
So-called " absorbent-type artificial leg " appears subsequently, the light plastic cement of material operating weight that wherein is used for receptive cavity, wherein use not only closely cooperate (not having the slit) also to fit closely to the liner of deformed limb to receptive cavity, and the air that is stuck in the receptive cavity is emitted by valve, thereby guarantees the performance that hangs.By like this, improved the transmission efficiency of power, and made and not need suspension strap, thereby provide flexibly and allowed to be easy to the artificial leg of walking.On the other hand,, cause the deformed limb outofkilter, make the parts do not absorb sweat and to fit closely to skin be inserted in the plastic cement receptive cavity with breathability by the liner that employing has the structure that seamlessly fits closely to receptive cavity and deformed limb.
In nineteen nineties, propose this artificial leg and propagate fast, make liner be further development of and have pin (pin) in the bottom, and be formed on receptive cavity in the artificial leg and provide pin and be contained in wherein hole separably.Connecting pin and receptive cavity and do not have " move (play) " make " when the walking unnecessary piston reciprocal " that produce probably in conventional leg prostheses almost completely eliminate.Simultaneously, pin has this structure, and wherein pin provides locking mechanism, makes that pin automatically locks, and can easily discharge locking from the outside when pin fits in the receptive cavity.
At length, under the situation of this pin formula artificial leg, the reciprocal action between artificial leg socket and liner is almost ideal.If deformed limb can not be coupled in the liner troublesomely fully, and in the use of artificial leg, do not find trouble, can obtain integrity so.
Yet the metallic pin (being made by rustless steel usually) of installing safely and steadily and have equivalent length (usually approximately 7cm) is difficult to the main liner of being made by silicone rubber.And the engineer who produces artificial limb can't rely on manual operations to finish above-mentioned work.Therefore, adopted such mode, wherein from the liner that has made of various sizes, select to have any liner, and this liner of meticulous adjusting has been to have obtained to be suitable for relevant amputee's liner near the size of relative dimensions.The liner that is obtained by this method is very expensive.
Concerning maker, the setting of the various sizes of liner causes monovalent increase.In fact only prepare approximate size.As a result, not just to have restriction naturally by adjusting or reprocessing, arranging corresponding to the liner of any special size of amputee.And the amputee is in the existence of worrying near the metallic pin of deformed limb, is forced to use even size is not suitable for amputee and even quite expensive artificial limb.
Concerning the amputee who uses artificial leg, ideal artificial leg is the artificial leg that can experience the return of healthy leg.Mating part between deformed limb and liner is perfect condition now far from.If there are a plurality of slits between deformed limb and liner, deformed limb is unstable in liner so, and is difficult to carry out walking movement concerning the amputee.Eliminating in the slit between deformed limb and the liner, there is not breathability, thereby causes sensation sticking when antiperspirant is arranged, produce stink, perspiration and produce skin problem to cause under the close-fitting each other situation of deformed limb and liner.In addition, the never close-fitting easily deformed limb of liner is taken away, and makes and to be difficult to remove liner from deformed limb and closely cooperate.
The such structure of liner that is used for pin formula artificial leg makes that adjusting hardness arranges on internal layer (surface that contacts with deformed limb) with the silicone rubber that impels the sensation that is suitable for skin, and liner is wound with the Fibre Bag of the energy that is ductile.Liner is mounted or is assembled to deformed limb, makes when pushing the whole surface of deformed limb, and the liner assembling also is fixed on the deformed limb.Yet, this structure in fact be not used in " accurately adjust " and the space.As a result, this situation is arranged seldom, wherein the size of its deformed limb amputee that fortunately is suitable for the approximate size of the aforementioned liner that has made once in a while obtains good artificial leg.
Summary of the invention
Consider the problems referred to above, the present invention studies energetically, and developing a kind of liner, it is multiduty and to provide and to realize the present invention at a low price, it is characterized in that the parts that are used for artificial limb comprise: substrate parts, and make and have a breathability by fiber cloth; And a plurality of projections, it is by making at the inner surface of substrate parts and the silicone rubber on the outer surface, and the projection of adjacency is separated from one another.

The specific embodiment
From the plug-in type artificial leg that hangs by band to keep the type of receptive cavity by absorption affinity, further to the improved history of the artificial leg of catch pin type artificial leg, the function that requires liner to have increases on degree gradually, makes deformed limb be in cruel situation.The inventor judges that reason is that the adaptation that can not escape between the inner surface of deformed limb and liner is only obtained such tradition common recognition by closely contacting mutually of material.This starting point of the present invention just.
In the present invention, the inner surface of substrate parts and outer surface are not level and smooth, and all are provided with a plurality of projections.Because projection made by silicone rubber, though projection itself does not allow air to pass through them, the projection of adjacency is separated from one another, from but each independently, make and guarantee to have breathability by the substrate parts that the fiber cloth with breathability is made.
In addition because the projection of adjacency is separated from one another, from but each independently, when being clothed to substrate parts on the deformed limb or being installed to receptive cavity, each projection easy deformation makes projection when so being out of shape, and substrate parts is suitable for being clothed on the deformed limb or is installed to receptive cavity.The disorder of internal organs of being in luck of being expert at, each in the projection recovered from distortion, thereby and further once more distortion cause obtaining to equal the suspension force of absorbent-type along the change of the shape of substrate parts.
As previously mentioned, described a plurality of projection is made by silicone rubber.The shape of each projection is not special definition, but can use various ways, for example hemispherical, discoid, conical or the like.On the surface of substrate parts, provide projection can utilize the method for adhered particles shape material to carry out.In addition, the suitable method that in inventor's test, is used for this discovery be on the surface of substrate parts, apply gradually have a high viscosity dissolve body (drip shape), and be full of at substrate parts to make under the situation of a part that dissolves body that is applied and dissolve body and solidify.The size of projection can be preferably 2mm * 2mm to 10mm * 10mm on width, and in height is approximately 2-5mm.In addition, each is separated from one another for the projection of adjacency.About the setting of projection, be preferably in the ratio of the setting of substrate parts upper process and account for 30% to 70% of whole zone.Because the neighboring part according to substrate parts of the present invention does not enter receptive cavity, so it does not need to be provided with projection.
Substrate parts is made by the fiber cloth with breathability, and the not concrete special material that limits.In addition, substrate parts can be tubular or plane.Under the situation of using cylindrical shape, substrate parts can use in the mode identical with traditional liner.
Under the situation that forms plane substrate parts, at first twine deformed limb, and push in the receptive cavity subsequently with plane substrate parts.Decide suitable bed knife by amount and the location arrangements of adjusting substrate parts, twine deformed limb thus.Adjustment can arbitrarily repeat.Therefore, though need the skill of a point operation, the operation that is used for plane substrate parts does not bother.
Embodiment
Next, will provide of the present invention further describing with reference to the accompanying drawings.
Fig. 1 illustrates the example (hereinafter referred to as " parts 1 (according to the present invention) ") that is used for the parts 1 of artificial limb according to of the present invention.
Shown in clear among the figure, the base portion of parts 1 in this example is a cylindrical body, is tapered and outer surface and inner surface are provided with a plurality of graininess projections 2 to the bottom.The substrate parts 3 that forms cylindrical body is the fiber cloth with slight retractility, and the silicone rubber that dissolves with high viscosity drips shape and is applied on it, and being connected with substrate parts 3, thereby formation is according to parts 1 of the present invention.Thus, even after granule shape projection 2 is formed on the surface of substrate parts 3, also can keep the breathability of substrate parts 3.
Fig. 2 illustrates graininess projection 2.On the substrate parts 3 as shown in Fig. 2 (a), be provided with a large amount of graininess projections 2, wherein the projection 2 of adjacency is separated from one another.The shape of projection can differently be used taper shape among cylindrical, Fig. 2 (d) among the hemispherical shown in Fig. 2 (b), Fig. 2 (c) or the like.
As shown in Figure 3, the method according to use parts 1 of the present invention begins to amputee's deformed limb with installing component 1.In this case, the graininess projection 2 on the inner surface side of parts 1 contacts with the surface of deformed limb.Though parts 1 are not only to closely cooperate (as there not being the slit) to receptive cavity but also fit closely to deformed limb, must have specific size in this case substantially to be enough to preventing that parts 1 are from deformed limb landing easily.
Subsequently, deformed limb embeds in the receptive cavity 41 of artificial leg 4.Some trouble of embedding operation.When deformed limb embeds in the receptive cavity 41, the space that the air of compression is determined by the step that is formed by graininess projection 2 or spill from substrate parts 1 owing to the breathability of substrate parts 3 self.Thus, than the situation of using traditional adsorption-type receptive cavity (wherein air is discharged by the valve that is arranged on the receptive cavity bottom surface), embedding operation is very easy to carry out.
Fig. 4 (a), 4 (b) and 4 (c) illustrate other examples of the present invention.Parts 1 according to the present invention in this example are in plane but not tubular.Parts 1 shown in Fig. 4 (a) are almost rectangle, and for having the shape of center circle plate-like part 11, band portion 12 radially extends from plate-like part 11 simultaneously, and is the shape by thin film 13 connecting band parts 12 in Fig. 4 (c) in Fig. 4 (b).In these parts, both sides before and after graininess projection 2 is arranged on.It should be noted that on thin film 13 parts shown in Fig. 4 (c) and do not have graininess projection 2.In the use of parts 1, at first, the distal-most end of deformed limb is applied to the middle body of the parts 1 that will twine fully, and embeds subsequently in the receptive cavity 41.Make the middle body bearing load, thereby and can be manufactured to thicker than other parts around middle body.Because parts 1 are plane, when when deformed limb breaks away from, the part of parts 1 is folded more severely.When parts 1 are clothed to deformed limb, need consider this point, therefore need experience.Simultaneously, the parts 1 that any parts (as metallic pin or the like) are not set itself do not need machine-building or adjustment, thereby allow so that parts 1 to be provided very at a low price.
Provided the detailed example of artificial leg about aforementioned explanation of the present invention.The present invention is applicable to the arm prosthesis (not shown) fully.
