Technical Field
The invention relates to a prosthetic foot to be used in the prosthetic-orthotic sector.
In particular, the invention relates to an apparatus for preventing breakage caused by extreme loads, with a prosthetic foot having rotations of +/- 4 degrees of torsion (torsion movement) to the connecting section, slits providing the main body with a multi-axis structure, and rings preventing deformation during flexing of the main body.
Known Status of Technique
Prostheses are externally used artificial limbs to perform individual walking and daily activities as a result of accidents, tumors, vascular diseases and diabetes. For optimal use, a prosthesis must have a lightweight, high flexing and gripping ability that does not disturb the user during use, and at the same time it should have a long life.
Today, with technological advancement, more and more ideal solutions for prosthetic users are being considered every day and new products are being developed. In the present technique, carbon fiber prosthetic feet are used to provide lightness and flexibility. However, in order for the product to have a longer life span, a prosthesis foot structure is needed that does not have the risk of fracture with the flexion limits controlled. As a result of frequent use of prosthetic feet, deformation is likely to occur. The first stretching movement occurs at the front of the foot during the step is taken. During the step, the front edges or fingers of the carbon foot come in contact with the end of the movement and take the weight of the body as well and make a bending motion at the end of the step. The continuous formation of the bending movement causes permanent bending or crushing on the carbon foot. For this reason, carbon-alloyed coils, which will increase the strength on the carbon feet, are now being used frequently. However, it is necessary to fix it to the foot area so that the winding does not spread again. The strength and life span of the region wrapped with carbon fiber is increased and as a result of deformations in the rope section, the structural properties of the carbon foot deteriorate and cause the prosthetic foot to be changed. In the present system, the inner surface of the prosthetic feet is produced in a smooth manner and sharp edges and protrusions are formed on the surface of the foot when it is wound from the outside. Deformation caused by this condition requires complete replacement of the prosthetic foot. ΪB-ER MAKINA SANAYi VE TiCARET LTD.§Ti. application with issue number TR 2013 13346 for beneficial model is about a prosthetic foot with flexibility control.

Detailed Description of the Invention
The invention is intended to prevent break which may occur under stresses that may occur under extreme loads, a prosthetic foot (100) having an internal element (30) which limits the flexure of the main body (10) and the slits providing the multi-axis structure in the main body (10) and the rotation of the connection part (40) in the A and B directions by +/- 4 degrees.
Figure 1 shows a side view of the prosthetic foot (100) and Figure 2 shows a front view. The prosthetic foot (100) comprises a main body (10) and a lower body (20) connected to the main body (20) and an internal element (30) connected to the main body (10) by means of a bolt. Said main body (10) and lower body (20) comprise of a right edge (1 1 , 21 ) and a left edge (12, 22). Said right (1 1 ,21) and left edges (12,22) are connected to each other at the tip by means of carbon fiber rings (60,61 ). The housing of the interconnecting carbon fiber rings (60, 61 ) is created by pre-machining on the main body (10), and the housing width is adjusted in the personally controlled gauge. The inner and outer surfaces of said rings (60, 61 ) are radial, and at the front of the prosthetic foot (100) there are also grooves that allow the rings (60,61 ) to fit into the groove. When the rings (60, 61) are placed in the grooves, the strength of the front surface increases. On the outer surface of the rings (60, 61), there are cavities for winding the carbon / fiber rope so that the rope is consistently wrapped by the confined cavities on the ring surface during winding.
Outside corners of the wrapped rings (60, 61 ) has a radius not a 90 degree corner. This radius prevents the carbon fiber rope making a 90 degree turn against the carbon fiber foot. By having the radius, this prevents the carbon fiber rope from bending and creating a weak spot. By having the carbon fiber rope in cavities and have controlled corner radius, this allows to make the corner with less stress.
In the event of a problem on the prosthetic foot (100), only the rings (60, 61 ) can be removed instead of the entire foot being replaced.
The main body (10), which is shown in Figure 3 as top and side view in Figure 4, has a flexibility enhancing portion formed by imparting a "C" shape at the end near the heel. On the flexibility enhancing part, the connection part (40) of the prosthetic foot (100) providing the connection with the leg is positioned. There are at least two slits on said flexibility enhancer. Starting from the flexibility enhancing section, these slits continue downwardly joining together at the base of the main body (10) and divide the main body (10) into two parts, the right and left edges (1 1 , 12). With this configuration, the prosthetic foot (100) has freedom of movement in the A and B directions (torsion movement) by +/- 4 degrees in the connection part / middle key (50), which provides connection to the legs. As a result of the fact that the main body is also made of two separate edges, the prosthetic foot (100) is provided with a multi-axis structure. In addition, the prosthetic foot (100) is provided with a high flexibility by virtue of the fact that the main body (10) is in the form of "C" and made of carbon fiber material.
The internal element (30) serves to limit this strain, which occurs when the main body stretches (10) under extreme loads. The main body (10) resiliently rests against the internal element (30). Thereafter, the internal element (30) is also fixed by some stretching. As a result, the prosthetic foot (100)'s stretching stops in full. Thus, the main body (10) is prevented from flexing to create a risk of fracture. Figures 5 and 6 show a prosthetic foot (100) having a two-ring model. At the end of the step in heavy people, the load on the prosthetic foot (100) may cause various twists in the tip and trunk of the main body (10). In the end of step movement, the right and left second rings (70, 71 ) are the connection elements between the main body (10) and the lower body (20) by providing a more comfortable stretch of the main body (10). The radius in the rings (60, 61 ) are of standard size, so that the effect of the fracture created by the sharp edges is less than that of the wrapping methods.
Figure 7 shows the side and cross-sectional view of the ring model. The thicknesses and sizes of said rings (60, 61 ) can be varied according to the type of people in different weights, and they are made in the appropriate thickness of the carbon foot (10). Invention also is that the slits in the flexibility enhancing section that provide rotation capability (torsion movement) in directions A and B +/- 4 degrees to the connection part (40) providing the connection of the prosthetic foot (100) to the leg may not join at the base of the main body (10). It is also possible that the number of slits can be more than two. The channel opened to create +/- 4 tails is in contact with the tip point of the lower body (20). During walking, the middle key (50) carries the body burden to the lower body (20) and flexes towards the lower body (20). This improves patient comfort by creating a rolling feeling on the wrist part.
