Abstract

Description
PROSTHESIS INTERNAL SHAFT SYSTEM
Field of the Invention The invention refers to a prosthesis internal shaft system with an internal shaft which is attached within an external prosthesis shaft.
Backgound of the Invention Prosthetic elements, such as prosthetic knee joints, artificial lower legs or artificial hands are attached to prosthesis shafts, which are situated on the relevant stump of the prosthetic user. According to the desired scope of function, there is a differentiation between purely cosmetic prostheses, mechanically activated prostheses or bioelectrically controlled prostheses. The relevant extremity to be replaced, or function element, or impetus are located on the exterior shaft, which is attached directly to the internal shaft on the stump.
In myoelectrically powered prostheses, the conduction of an electrical action potential from the stump musculature is necessary. These potentials are emitted by the contraction of a muscle and are measurable on the skin surface of the prosthetic wearer.
The potentials collected by the electrode are amplified and sent to the control unit, which activates or deactivates the actuators. The state of the art is to equip the internals shaft with a recess in which the electrode can be inserted. Between the electrode and the recess in the internal shaft there is a particular gap which can lead to a relative movement between the electrode and the internal shaft. Through the gap between the internal shaft and the electrode, sweat can enter the space between the internal shaft and the external shaft, which can affect the electrical and electronic components.
This can also make cleaning the internal shaft difficult.
Summaa of the Invention The task of this invention is to provide an improved internal shaft system in which these disadvantages do not arise. According to the invention, this task will be solved by a prosthesis internal shaft system with the characteristics in claim 1.
Advantageous design and additions to the invention are discussed in the subsequent claims.
The prosthesis internal shaft system in accordance with the inventions with an internal shaft which is constructed within a prosthetic external shaft with accommodation features for further prosthetic components, and has at least one recess provides for the conduction of myoelectrical signals to an electrode located on the internal shaft, whereby the electrode is attached to a fitting enclosed in the recess. It is therefore possible, to construct the internal shaft as a suction shaft, so that there is no gap between the internal shaft and the electrode or electrode fitting. Air or sweat cannot enter or exit the space between the electrode fitting and the internal shaft.
Therefore the rest of the prosthesis components or the accumulator is protected from sweat. For cleaning or when using a skin cream, no material can be retained in the external shaft.
Through airtight assembly of the fitting with the electrode onto the internal shaft, there is a vacuum effect, so that there is better contact between the stump and the electrode as well as a secure hold of the internal shaft system to the stump. In addition, the manufacture of the internal shaft is made easier, because it can be constructed as a laminated or deep drawn intern shaft, into which the recess is cut in accordance with the stump model after the shaft is completed.
The fitting consists, preferably, of an elastic material, in particular silicon or another skin friendly or cutaneous tolerant material. The electrode can be injected into the fitting, for example within the framework of a two component injection method, or adhered, pressed or form-fit and enables a sealed position. The groove is preferably built circumferentially into the fitting, so that the fitting completely covers the internal and external edges of the recess. In this way, the internal shaft is enclosed within two seal lips, which are located close to the internal shaft.
An extension of the invention provides that the internal shaft is attached to the external shaft with a tube onto which additional prosthesis parts are attached. This tube would be required for insertion of the stump into the internal shaft. A
unidirectional valve is attached to the internal shaft which presses air out of the area of the internal shaft with every movement of the stump. The valve can be located within the connection tube between the internal and external shafts and closes this. Through relevant adjustment of the valve to the attachment tube, the entrance of soft tissue into the tube is hindered.
It is preferred that the fitting be spring equipped or pliable, in order to equalize irregularities in the form of the stump, so that the electrode contacts always have good contact to the skin.
The side of the fitting turned toward the stump is flattened, in particular, in the shape of a spherical cap, So that the shape of the injection part with the integrated electrode has no or only slight pressure points, because the fitting hardly comes away from the surface of the side of the internal shaft.
For better insertion of the fitting into the internal shaft by pressing or snapping into place, a sealant can be used in the groove or in the contact area between the internal shaft and the fitting, for example, silicon, which can provide a better seal.
Brief Description of the Drawings The following elucidates more closely a design example using the included figures. It shows:
Figure 1: A fitting with inserted electrode in a top view and side view;
Figure 2: a perspectivist representation of the electrode in a top view from above and below.
Figure 3: A fitting without electrode from the internal side of the shaft;
Figure 4: the back side of the fitting pursuant to figure 3;
Figure 5: An internal shaft with inserted electrode, as well as Figure 6: a partially cut away external shaft with inserted internal shaft.
Detailed Description of the Drawings In figure 1, fitting 1 is shown with electrode 2 inserted, the electrical connections 3 for conduction of the action potentials of the muscle groups via the skin contacts 4, 5, and 6. In the left side view, the spherical cap construction of the stump side surface 13, the fitting 1, the groove 10 and the retention bar are seen. In the groove, 10, the internal shaft is inserted. Through the pressing of the electrode fitting from inside to outside in a recess in the internal shaft that is so large that the contour is assumed within the groove 10, and is covered by the internal side of the fitting 1 and the retention bar 11, an air and watertight seal is created within the internal shaft. A rotary switch 7 on the back side of the electrode enables an adjustment of the mounted electrode 2.
The electrode 2 can be injected, adhered, pressed or form-fit into the fitting. In the perspectivist view in figure 2, one can see the finished mounted electrode 2 in fitting 1.
With a multiple component design of electrode and fitting, the fitting 1, as shown in figures 3 or 4 in various views, is made of a molded part or injection molded part of a skin tolerable material, silicon for example and is equipped with a recess 12 for the insertion of the conduction electrode 2.
In figure five, the internal shaft 3 is represented diagonally from the back, from the insertion direction of the stump, an arm stump, in the example. The internal shaft 3 is constructed as a suction shaft and displays an electrode 2 on the internal side which is attached to the internal shaft 3 via a spherical cap fitting. The contour of the fitting 1 on the internal side of shaft 3 is only slightly convex, in order to provide the most comfortable feeling for the wearer without pressure points while providing a secure connection to electrode 2 on the stump, so that there is a durative electro-myographic signal. As described above, the fitting 1 is equipped with groove 10, which the internal shaft grabs, so that the required recess is sealed against air and moisture.
In figure 6, we have a prosthesis part with an internal shaft 3, and an external shaft 4, whereby the external shaft is shown in a partial cutaway representation. The internal shaft 3 is secured via screws 34 to the stabile exterior shaft 4. In addition, a bore hole 32 is provided in the external shaft, through which the electrode 2, which is attached to internal shaft 3, can be adjusted by rotational switch 7.
In the partial cutaway representation we see that the internal shaft 3 is attached to the external shaft via a connection tube 5. The connection tube 5 enables an escape of the air in the internal shaft to an appropriate location in the externals shaft.
In order to prevent back flow of the air, there is a unidirectional valve located in the connection 5 tube 5. Through use of a lever 15, an o-ring 16 is activated within the connection tube 5 and thereby seals off the internal shaft 3. Air can then only escape through he unidirectional valve.
