Description

ML

Orthopaedic-therapeutic shoe insoles are very important in the field of orthopaedics. Indications include, for example, the straightening of the longitudinal arch of the foot, children's flat feet, the support of the longitudinal and transverse arch as a detorsion insole with pronation of the forefoot, the three-point insole for previously treated clubfoot or sickle foot,
children's flat feet.

According to the current state of technology, it is still common to create impressions of the foot or feet and models tailored to them, whereby plaster is still the material of choice, while the insoles are made from epoxy resin, leather, leather and metal, Plexidur or similar.

This naturally has the disadvantage that a therapeutic insert has to be formed from the static situation, which

The desired therapeutic result is constantly lagging behind due to corrections. The manual effort required for this is also considerable.

The object of the invention is therefore to use existing electronic data processing or data processing that is in need of improvement or expansion to

To simplify the creation of orthopedic shoe insoles and to optimize the therapeutic purpose.

For this purpose, a kit is proposed that consists of a specific X-ray unit that allows X-rays of the foot to be taken without weight bearing and with body weight bearing, whereby the comparison of the X-ray images allows diagnostic statements and therapeutic steps to be planned. The possibility of

The fact that data processing can be used to scan the X-ray image, for example, and to implement the data in the overall kit should only be mentioned peripherally.

The second kit element in the proposed variant is a scanning frame with corresponding scanning elements, which can preferably be moved and fixed hydraulically or pneumatically, so that it is possible, on the one hand, to scan the respective foot in step without load and preferably under the influence of body weight using the large number of scanning elements and to save the result in a computer. The software makes it possible to create a three-dimensional image of the foot, preferably by scanning the supporting scanning points, so that the subsequent insole can be therapeutically planned in advance on the computer using the controlled pneumatics or similar.

This is made possible by the fact that each scanning element is preferably connected to a pneumatic or hydraulic cylinder piston device that can be controlled by a reducing valve, for example, with a hose connection to a corresponding compressed air unit, whereby the reducing valves can be controlled electronically, for example via a digitizing tablet, and when the scanning elements are enabled, a three-dimensional image of the later
Insert under load.

The further process is preferably carried out using a directly controlled free-surface milling machine, which forms the insole bed from insole blanks made of the appropriate material. Software is provided for incorporating it into the orthopedic shoe, at least the combination of insole and shoe sole.

An alternative is manual finishing.

The invention will now be described with reference to the method claims 1-12 and the kit claims 13-23 as well as the figures 1-4
explained in more detail.

Figure 3 shows a schematic of an isolated scanning element with its pneumatic, hydraulic or other control options, whereby a pneumatic variant was preferred here.

Figure 1 shows a schematic flow diagram of the entire kit.

We can see the X-ray unit (1), which is connected online (21) to a PC (computer, programming unit) (4) as well as an online path (21) to the guide frame (8) with its scanning elements (9). Each of these scanning elements (9) can preferably be scanned digitally in its length change or (only) by scanner (22) in the

The entirety of all scanning elements (9) can be captured three-dimensionally via a screen (14), whereby the result or the image generated can be archived in a memory unit of a computer (4) (e.g. additionally via diskette or similar) and/or reprogrammed using the same computer (4), which ultimately leads to a change in the position of the scanning elements (9) under load.

The result of this programming is the preferred control of a 3-D milling unit (5) via a preferably electronic drawing table (15), which (5) designs insert blanks (6) possibly in combination with an orthopedic shoe sole according to the footbed.

Figure 2 shows a schematic representation of the preferred guide frame (8) with two scanning elements (9), whereby only one (9) shows a possible pneumatic connection (11,12,16,...). The guide frame (8) itself is secured to the sketched clamping device (19) by means of an eccentric or, if necessary, an electronically controlled

Motor (24) lockable (21).

Figure 3 shows once again schematically an isolated scanning element (9) with its end rounding (13), which serves as the footrest and which (9) is connected at the end via the hose connection (16) preferred here to the pneumatic components (11, 12) with reducing valve (17), the latter being electronically controllable (21) and connected to a compressed air unit (23).

Figure 4 shows a schematic, detailed section of the guide frame (8) under foot load of the indicated scanning elements (9).
