Prosthetic foot Detailed Description of the Invention Invention is to prevent fractures caused by stretching that may occur under excessive loads, to ensure the safety of the person; A and B up to +/- 4 degrees to the connection section (40) ability to rotate in the direction of rotation (torsion movement), multi-axis structure on the main body (10) It has slits that allow the relates to a prosthetic foot (100) having element (30).

Side view of the prosthetic foot (100) structure in figure-1, front view in figure-2 are given. Accordingly, the prosthetic foot (100) consists of a main body (10) and a main body (20). a lower body (20) connected to it, and the inner body (20) connected to the main body (10) with the help of a bolt. consists of elements (30). Said main body (10) and lower body (20) are right sides. (12,22) on the nose with the help of carbon fiber rings (60.61) one on top of the other. are linked to each other. The slot of the carbon fiber rings (60, 61), which provides the connection, It is created by preprocessing on the main body (10) and is individually controlled. The slot width is adjusted within the dimensions. The inner surface of said rings (60, 61) It is radiused and ensures that the rings (60, 61) are fully seated in the socket on the front part of the prosthetic foot (100). There are grooves that provide it. If the rings (60, 61) fit into the grooves, the front surface its strength increases. Winding of carbon / fiber rope on the outer surface of the rings (60, 61) There are recesses for the ring, limited cavities on the ring surface during winding. Thanks to this, uninterrupted winding of the rope is ensured.

The outer corners of the wrapped rings (60,61) are not 90 degrees, they are radii. This radius structure, It prevents the carbon fiber rope from turning 90 degrees on the carbon fiber foot.

Thus, the carbon über prevents the rope from twisting and creating a weak point. carbon fiber rope Being in cavities and having a controlled corner radius, corners are less it provides voltage.

In case of problems on the prosthetic foot (100), replacement of the whole foot instead, only the rings (60, 61) can be removed.

The main body (10), whose top view is shown in figure-3 and side view in figure-4, is “C” at the end close to the heel. It has a flexibility-increasing part created by gaining its form. Flexibility enhancer the connection part (40) that provides the connection of the prosthetic foot (100) with the leg on it is positioned. At least two slits on the said flexibility enhancer are available. These slits start from the flexibility increasing part and descend downwards. it continues by joining at the base of the body (10) and extends the main body (10) to the right and left. It divides it into two parts, the edge (11, 12). Thanks to this structuring, your prosthetic foot (100) in the connection section that provides the connection to the leg / middle tongue (50) +/- 4 degrees A and freedom of movement due to the ability to turn in the B direction (torsion movement) it provides. As the main body is formed from two separate sides, the prosthetic foot (100) is brought into a multi-axial structure. Besides all these, the main body (10) ”C” The prosthetic foot (100) is high in shape and made of carbon fiber material. flexibility structure is gained.

The inner element (30), in case the main body (10) flexes under excessive loads, prevents this flexing. he is in charge of irritating. The main body (10) flexes and abuts against the inner element (30).

Subsequently, the inner element (30) is fixed by some stretching. As a result, the prosthesis The flexing of the foot (100) also stops completely. Thus, the breaking of the main body (10) It is prevented from flexing in a way that creates danger. Two rings in figures 5 and 6 The prosthetic foot (100) having a model is shown. Prosthetic foot at the end of the step in heavy people The load (100) on the main body (10) causes various bending in the end and body part. can give. In the end-of-step movement, the right and left second rings (70, 71) of the main body (10) connection between the main body (10) and the lower body (20) by allowing it to flex more easily. element. The radii inside the rings (60, 61) are of standard size, so The breaking effect of sharp corners is reduced to a lesser extent than wrapping methods. is happening.

In Figure 7, the lateral and cross-sectional view of the ring model is given. Of the mentioned rings (60, 61) thickness and size may vary according to the type of people with different weights, carbon foot (10) It is made in suitable thickness.

The invention also includes the connection of the prosthetic foot (100) to the leg in the flexibility enhancing part. Ability to rotate +/- 4 degrees in A and B directions to the connecting part (40) that provides The slits that provide (torsion movement) may not converge on the base of the main body (10).

It is also possible for the number of slits to be more than two. +/- 4 drop-downs to create flavors the channel contacts the apex of the lower body (20) curve. Middle tongue while walking (50) causes the lower body (20) to flex towards the ground by carrying the weight of the body to the lower body (20). it provides. This situation creates a rolling sensation in the wrist, increasing patient comfort. is increasing.
