Definitions

• the invention relates to a prosthetic foot to be used in the prosthetic-orthotic sector.
• 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.
• Prostheses are externally used artificial limbs to perform individual walking and daily activities as a result of accidents, tumors, vascular diseases and diabetes.
• 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.
• a prosthetic foot with flexibility control consisting of a top plate and a bottom plate connected to said top plate, an inner member providing elasticity control by extending a flexure-enhancing portion constructed by imparting a C form to the tip of said top plate close to the ball, a resiliency enhancing portion structured by imparting a form of C; a resiliency- between the moment that the force is generated by the ball, the resilient support element in the flexible structure is positioned.
• the present invention relates to a prosthetic feet with flexible ankle structure that meets the above requirements, removes all disadvantages and adds some additional advantages.
• the object of the invention is to provide the user with a long-lasting and comfortable operation due with its lightness, flexibility and durability values for the user.
• the object of the invention is to create a controlled bastion with the reason for the breadth and depth of the rings on it.
• the object of the invention is to provide a time saving benefit by easily changing during the modification.
• the object of the invention is to provide movement capability by virtue of the torsion movement (torsion movement) of the connection section of the prosthesis to the bridge by virtue of the slots in the flexibility enhancer formed by imparting the form "C" at the tip of the main body.
• the object of the invention is to provide a multi-axis structure to the main body to control the flexing limits, to prevent the break of the prosthesis and to increase the life span of the product.
• the object of the invention is to limit the stretching under the overloading of the main body by means of the internal element which it possesses.
• the outer radius shape surface of wrapped rings will allow to handle higher stress resists.
• the invention provides a prosthetic orthosis, in its most basic form,
• connection section providing the connection of the prosthetic foot to the leg, characterized in that: is that it has right and left rings that provide a stronger structure by acting as a connection element between the main body and the lower body.

• 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.
• FIG. 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.
• 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.
• the connection part (40) of the prosthetic foot (100) providing the connection with the leg is positioned.
• 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.
• the prosthetic foot (100) is provided with a multi-axis structure.
• 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).
• 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).
• 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).
• 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).
• 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.
