Description

Field of the invention

The invention relates to a system for the pre- and aftercare of hip joint patients.

State of the art

It is known that today many hip problems can occur in patients. If these are diagnosed in good time and if the diagnosis allows it, targeted movement of the joint and the muscles can have a preventive effect or at least alleviate the symptoms. In some patients, however, it comes to hip joint operations to the replacement of a hip joint. After a corresponding procedure usually a follow-up of the patient. Precaution and aftercare can be done by active movement, ie the patient moves his legs or joints. Frequently, an active movement of the legs is the patient but limited or at least temporarily hardly possible in appropriate situations. Here passive approaches can be added, either to support or replace the active movement, at least until the patient is able to actively move again. For passive movement, for example, one or both legs of the patient mechanical aids can be used. To be carried out movements, in which, for example, a leg of the patient is in connection with the aid must be carried out as precisely as possible for a certain time. For example, these movements can be repeated several times. For example, a certain cautious movement of a leg should be performed for a few minutes or, for example, twenty times in a row and thereafter performed again with minor changes in the motion parameters. In addition, in some movements, a cautious relief of the affected joint is desirable, which should be in addition to the movement of the leg. However, it is very difficult for a person, for example a masseur, to carry out the pre- or post-operative care of the patient, to carry out relieving and / or joint-building movements of the patient's leg manually. This is where the device starts. The possible variability of the device at the same time Precision and safety of the user are problems that the present invention seeks to solve.

Description of the invention

This object is achieved by a system for the pre- and aftercare of hip joint patients according to claim 1. In the following, the terms pre- and post-treatment on the one hand and pre- and post-treatment on the other hand are used synonymously.

The invention provides a system for the pre- and post-treatment of hip joint patients comprising: a first support member movable in a first plane on which at least one leg of the patient or body of the patient is storable and fixable; a second support element which is movable in a second plane, on which the body of the patient or at least one leg of the patient is storable and fixable; wherein the first and second support members are movable relative to each other; at least one first drive for moving at least a portion of the first or at least a portion of the second support element relative to the second or relative to the first support element from a first position to a second position and back again, wherein both the first and the second position in the first Level or in the second level.

It is understood that the patient, so the body of the patient, typically lies or sits on one of the two support elements. One or both of the legs of the patient store / store accordingly on the other of the two support elements. If only one leg is considered, then the considered leg belongs to the half of the body of the patient, which comprises the hip joint to be pretreated or subsequently treated. For the sake of simplicity, the following is also spoken of the leg to be treated. This should be understood as meaning the relationship between the leg and the hip joint to be treated. The leg of the patient to be treated points substantially in the distal direction. The relative movement of the two support elements to one another makes it possible to move the patient's legs or legs relative to his body or to move the patient's body relative to his legs. In this case, the first and / or the second support elements comprise one or more parts, so be constructed in several parts. In this case, in each case at least one of the parts of the first and / or at least one of the parts of the second support element can be movable. In this case, a movement can be achieved, which take place essentially in the first plane or in the second plane can. Thereby, a reciprocating between a first predefined position and a second predefined position can be ensured. The positions may be variable, for example, a leg may be gradually moved farther outward from the body center. As part of a treatment, both support elements can be moved, whereby a great deal of flexibility can be achieved.

In the system, the first and / or second support members may each comprise at least one support point and a support; wherein the leg of the patient or the body of the patient can be placed on the support and fixable; wherein the support can touch the support point and relative to the support point in a translational and / or rotational movement in the first and in the second plane can be movable; wherein the at least one first drive may be configured to move the support relative to the support point from the first position to the second position and back again.

In the system, the support point may be a pivot about which the support may be rotatable.

For example, the patient can sit on a rotatable chair, which is rotatable about the pivot point.

In the system, the first and / or the second support element may comprise a support surface, and the support may comprise lubricants or rolling means with which the support may be slidably or rollably movable on the support surface.

The support may additionally be provided on its underside, for example with a lubricious layer or foil or plate as a lubricant or rollers as rolling means. Thus, the friction, such as static friction, sliding friction or rolling friction, the support against the support surface can be reduced, so that the support can be easily move on the support surface. This is as little kinetic energy lost by friction on the support surface.

The system may further comprise at least one second drive for moving at least a portion of the first or at least a portion of the second support member relative to the second or relative to the first support member from a third Position in a fourth position and back again, wherein both the third and the fourth position lie in the first plane and in the second plane.

Thus, two movements can take place, on the one hand with the aid of the first support element from the first to the second position and possibly back again, on the other hand with the aid of the second support element from the third to the fourth position and possibly back again. Each of the two movements can be done independently of the other. One or both movements can be stopped selectively if necessary. If one of the two movements is stopped, the other movement can continue.

In the system, the first and / or the second support element may comprise a fixing element, which is designed to fix the leg of the patient on the first and on the second support element.

By fixing with a fixing can be avoided that the leg of the patient to be treated slips or slips off.

In the system, the second drive may move the first or second support member relative to the second or relative to the first support member such that movement between the third and fourth positions substantially in the direction of the longitudinal axis of the leg or in the direction of the longitudinal axis of the upper body Patients done.

The movement of the first support element relative to the second support element can typically be done so that the leg to be treated is carefully moved away from the body of the patient. In this case, an extension force / tensile force can be established. In this case, the first and / or the second support element can be locked, so that a once found position can be maintained with a corresponding extension force. The extension force / tensile force typically acts along the leg, ie in the direction of the leg axis of the patient in such a way that the hip joint of the patient to be treated can be relieved.

In the system, the first drive may be configured to control the movement path and / or the amplitude and / or the speed of the movement and / or the acceleration of the first and the second support element.

In the system, the second drive may be configured to control the movement path and / or the amplitude and / or the speed of the movement and / or the acceleration of the first and the second support element.

By preselecting the parameters of the movements, a rotary or translatory movement in the respective plane can be controlled. The control can be done in terms of the deflection of the leg from the body center to the outside, as well as in terms of the speed of the deflection and the repetition of the movement. It is understood that during this movement, the extension force and thus the extension of the leg can be maintained. The first and / or the second drive may each include a control unit, such as a computer. But there may also be a central control unit in the system. It is also possible to connect an external control unit to the system. One or more of the following motion parameters may be controlled and controlled for one or both of the drives: travel, speed of movement, change in speed of movement, amplitude / displacement of movement in the respective plane, predefined forces, and duration of movement. In this case, changes of one or more of these motion parameters can in each case be carried out at intervals, that is to say for a predefined period of time corresponding to a predefined number of movements. As a result, a great variability and adaptability of the system with regard to the specific conditions for the user / patient can be achieved. The system can therefore also be used at different times and phases, for example at early stages of treatment or even at advanced stages of treatment. Thus, the system can be used for prophylaxis and / or pre- and / or postoperative treatment.

In the system, the first drive and / or the second drive can be a manual and / or an electromechanical drive and / or a drive by means of force generation by spring preload, and / or pneumatic and / or hydraulic power generation and / or by force generation by own weight and / or or by weights.

By the different types of drive for the first and / or the second drive, a desired extension force can be preset and applied in a simple and effective manner. The preset extension force or tensile force can thus be kept practically constant or varied during operation. A suitable drive type for the first and / or the second drive can be selected.

In the system, the first and / or the second support element may comprise at least one guide means, wherein the support may be movable along the guide means.

Along a guide means, such as a guide rail or a guide rod or a guide groove, the support can be controlled moves, so be guided. For example, the support may comprise a carriage which is movable along the guide rail.

In the system, the first or the second drive can be provided on or on the support, such that the first or the second drive can move with the support.

In the system, the first or the second drive can move the support via a power transmission means, such as a drive belt or a chain.

In the system, the first and / or the second support member may comprise a first guide means and a second guide means, wherein the support along the first guide means and along the second guide means in the first and in the second plane is movable and the movement of the support takes place along the first guide means substantially perpendicular to the movement along the second guide means; wherein the first drive is configured to move the support along the first guide means, and further comprising a third drive configured to move the support along the second guide means.

By the first and the second guide means, which are provided perpendicular to each other, the support can be moved to desired, predetermined coordinates, in particular Cartesian coordinates (x, y) are moved. The movements in the x-direction or y-direction can thus be decoupled. By means of drives the movement can happen automatically. The third drive may correspond in type and design to the first drive or the second drive.

The system may further comprise at least one control unit, which may be configured to control the at least one first drive and / or the at least one second drive and / or the third drive and which may be formed during the movement of the first and / or To monitor the forces occurring in the second support element and the exceeding of predefined tolerances and / or predefined maximum values of the forces Disconnect movement and relax the forces; and the system may further include an emergency shutdown that can relax the forces upon the intervention of the patient or a caregiver.

In a passive system that externally performs a movement with a patient, here with the patient's leg or with the body of the patient, safety measures are important so that no overloading or uncontrolled stress on the patient can occur. A safety shutdown can either be carried out separately and, for example, be independent of the control unit or integrated into the control unit. For example, the safety shutdown can switch off the rotary or translatory movement immediately if predefined maximum values of speed, amplitude, forces, extension force or frequency are exceeded. Likewise, a shutdown can occur when deviations from the preset parameters, ie fluctuations, are greater than allow predefined tolerances. The shutdown can also be triggered by the patient himself, if the patient does not feel comfortable with the treatment. The forces can be relaxed or shut down during a safety shutdown. Thus, the passive load for the patient can be quickly reduced to virtually zero and the treatment can be continued as soon as the parameters of the system or patient demand have been checked or the patient with the Want to continue treatment. In the system, the control unit and / or the safety shutdown may be provided electromechanically and / or comprise a computer.

In the system, the first support element may be a couch and the support of the second support element may be movable on the couch, wherein the couch and the second support element form a unit.

Detailed description

The FIG. 1 shows a first embodiment of a system for pre and after care of hip joint patients. A patient P lies on a first support element 11. The support element 11 may be formed as a couch or bed. One leg B of the patient P rests on another, second support element 13. In this example, the right leg B of the patient P is shown. It is understood that for all embodiments shown as well, the left leg of the patient P could have been considered. For the selected right leg B, the patient's hip to be treated is the right hip. Accordingly, it would be the left hip for the left leg.

The second support element 13 may, as in FIG. 1 indicated, be shaped so that it can accommodate the leg B of the patient and the leg B can rest sufficiently firmly on or in the second support member 13 as well as possible comfortable storage for the patient P can allow.

The second support element 13 is provided movably on the first support element 11. For this purpose, the second support member 13 is practically on the first support member 11. The surface of the first support member 11 may be prepared for movement of the support member 13, so that the second support member 13 on the surface of the first support member 11 can slide or roll.

The second support element 13 can, as indicated by arrows 15, be moved with the leg B resting thereon essentially in the plane of the surface of the first support element 11. In particular, it can be moved from a first position to a second position and back again. The first and second positions can each be predefined positions. However, the positions may be changed during the treatment. The movement of the second support element 13, on which the leg B rests, can typically be done carefully from the body center to the outside. As a result, the leg B and thus the corresponding hip joint of the patient can be moved in the context of a therapy.

The second support element 13 can be moved by means of a drive (not in FIG. 1 shown).

The FIG. 2A shows a further embodiment of a system for pre and after care of hip joint patients.

In FIG. 2B is a detail view from the FIG. 2A shown. The support 21A is placed on a support point 21C on the support bracket 21 B and can be rotated about the support point 21C.

In the FIG. 2A the patient P is not on a couch, but he is lying or sitting on or in a support element 21. The support member 21 has in the FIG. 2A the shape of a chair, such as a dental chair. The treatment chair 21 comprises a support 21A and a support point 21C and / or a support support 21B. For example, the support 21A contacts the support point 21C at the tip of the support support 21B. The support support 21B may be columnar or frustoconical. The leg B of the patient P rests on a supporting element 23 in the example shown in FIG. 2A. The support element 23 may be adjustable in height. Likewise, the distance between the support element 23 and the treatment chair 21 may be adjustable. Thus, the system can be optimally adjusted in height and length to the required size of the leg to be treated. The support 21A is in the example shown with respect to the support point 21C of the support bracket 21 B movable in a rotational movement. For example, the support point 21C is a fulcrum about which the support 21A is rotatable. The movement of the support 21A relative to the support point 21C of the support bracket 21 B is indicated by the arrows 25. The movement can be done again from a first position to a second position and back again. The first and the second position can each be predefined positions. The rotational movement of the support 21A relative to the support point 21C of the support bracket 21 B can be done by a drive. The drive can be provided in the support 21 B.

In FIG. 3 A further development of a system 30 for the pre- and aftercare of hip joint patients is shown. The FIG. 3 based on in the FIG. 1 shown embodiment. A patient P is lying on a first support element 31, which may for example comprise a couch. The leg B of the patient P rests on a support element 33. The reference numeral 35 denotes arrows which indicate a movement of the support element 33 in the plane of the surface of the first support element 31. Additionally is in FIG. 3 an arrow 37 is shown. By a movement of the element 33 in the indicated arrow direction of the arrow 37, an extension force / tensile force can be built on the leg. The extension force typically acts along the leg in the direction of the leg axis of the patient P. By the train on the leg B, the hip joint of the patient P to be treated can be relieved. Typically, the applied force is a static force. That is, this force is typically held while a movement of the support member 33 in the direction as indicated by the arrows 35 is performed.

In FIG. 4 is a further development of the embodiment according to the FIGS. 2A and 2 B shown with different directions of movement. Similar in the FIG. 2A sits or lies the patient P on a treatment chair 41, the treatment chair 21 from the FIGS. 2A and 2 B can correspond. The patient P lies on a support 41A, which touches a support point of a support support 41 B. In this case, the support 41 B of the support 21 B from FIG. 2 correspond. The point of support (in FIG. 4 not shown) can the support point off FIG. 2B correspond. The leg B of the patient P is placed on a support element 43. The treatment chair 41 is rotatable relative to the support point of the support bracket 41 B. The rotational movement is indicated by the arrows 45. In addition, a movement of the support element 43 is indicated by the arrow 47. The movement of the support element 43 in the direction of the arrow 47 typically takes place along the leg axis of the patient P away from the body of the patient P. Similar to in FIG. 3 Thus, an extension force can be applied to the leg B of the patient P. In this case, the leg B can be suitably fixed on the support element 43, for example by means of a foot cuff or an ankle bracelet. Similar to in FIG. 3 For example, the extension force indicated by the arrow 47 can be maintained while the movement of the treatment chair indicated by the arrows 45 can be performed. Thus, the hip joint of the patient to be treated can be relieved again by the applied extension force, while the movement is carried out according to the arrows 45.

In FIG. 5 is a further development of the system of the first embodiment according to FIGS. 1 and 3 shown. In FIG. 5 a system 50 is shown for pre and post treatment of hip joint patients. Similar in the FIGS. 1 and 3 the patient P is on a support element 51. The leg B of the patient P rests on a further support element 53. This support element is in FIG. 5 but for example, separately supported (not shown here). A support, for example, as in the Figures 2 or 4 be provided. A movement of the further support element 53 is indicated by the arrows 55. This is again a movement of the leg B of the patient P in the plane of the element 51. The element 51 is in FIG. 5 practically horizontally divided into two parts. The element 51 comprises an upper part 51A and a lower part 51B. The patient lies on the surface of the upper part 51A. The upper part 51A is movable relative to the lower part 51B. These are in FIG. 5 several sliding or rolling elements 51C indicated. These elements may be formed, for example, as balls or as wheels or rods. As indicated by the arrow 57, the surface 51A may be moved substantially horizontally with respect to the lower part of the element 51 of the reference numeral 51B. The movement can take place substantially in the direction of the longitudinal axis of the upper body of the patient. At the same time, at least the upper part 51A of the support element 51 is moved away from the support element 53 in the direction of the arrow 57. The leg B of the patient P rests on the support element 53 and is typically fixed there. Thus, by the movement of the upper part 51A, a pulling force can be applied to the leg to be treated and thus to the hip joint to be treated. With the help of the tensile force / extension force, the hip joint of the patient P can be relieved. Meanwhile, the support member 53 can be moved independently of the movement of the upper part 51A of the support member 51, as indicated by the arrows 55. Thus, the movement of the leg B carried out with the aid of the support element 53 is substantially independent of the tensile force applied to the leg B with the aid of the support element 51.

The FIG. 6 shows a further embodiment of a system 60 for pre and post care of hip joint patients. In the in FIG. 6 As shown, the patient sits in an upright position on the element 61. The patient's legs are substantially down. The patient practically takes a standing posture. In addition, the patient may rest on a base 61A with the leg not to be treated. In the FIG. 6 the leg B to be treated is received by a support element 63. The support element 63 can be moved outward from the body center of the patient according to the arrows 65. For this purpose, a drive 68 can be used, which can enable a rotational movement about a fulcrum 68P. Additionally are in FIG. 6 shown on the outside of the element 63 weights 69. The weights 69 can exert a pulling force on the patient B to be treated by their own weight. For this purpose, the leg B is typically suitably fixed in the support element 63. The pulling force can, as indicated by the arrow 67, act substantially along the leg axis of the patient. The tensile force, which is indicated by the arrow 67, acts substantially independently of the movement of the support element 63, which is indicated by the arrows 65. It goes without saying that the tensile force is essentially is a static force and held, while the movement that is substantially perpendicular thereto, the element 63 can be performed.

In FIG. 7A is another development of the system according to the FIGS. 1 and 3 shown. In FIG. 7A there is shown a system 70 for the pre and postoperative care of hip joint patients. A patient P lies on a first support element 71. The leg B, which is to be treated in the course of the treatment, rests on a further support element 73. The support element 73 comprises a support 73A and a support surface 73B. In FIG. 7A the support surface 73B is shown as being placed on the support element 71. However, the support surface 73B may also constitute a table surface, as exemplified in FIGS FIGS. 8A . 9 . 10A and 11A is shown. On the support surface 73B, a guide means 79 is shown. The guide means 79 has a perforation so that it can be used as a rack for a drive. The leg B of the patient P rests on a support 73A. The support 73A may in turn be suitably molded to the shape of the leg B of the patient. On the support 73A, a drive 78 is provided. The drive 78 includes, for example, a gear 78A. The gear 78A of the drive 78 is formed so that it can engage in the rack 79A of the guide means 79. The support 73A is movably provided on the support surface 73B. Thus, through the drive 78, the gear 78A can engage the rack 79A and move the support 73A in the plane of the support surface 73B. FIG. 7A further shows a holding element 76 with a movable element 76A in the holding element. These elements are in FIG. 7B further explained.

In FIG. 7B FIG. 12 is a detail view of the embodiment of the system 70 of FIG FIG. 7A shown. The leg B of the patient P rests on the support 73A. The drive 78 can move the support 73 along the guide means 79 by means of the gear 78A. For this purpose, the gear 78A of the drive engages the rack 79A. The drive can be a manual or an electromechanical drive.

The element 76 includes a foot cuff 76F and, for example, a support bar 76A. In this holding bar, for example, is designed such that the foot cuff can be attached to the support rod 76A. For example, it can be hung over the handrail. The support rod 76A may be inserted into a cylinder 76B opposite the piston-like manner. The element 76 may further include a drive. Thus, the support rod 76A can be moved hydraulically or pneumatically. By applying a hydraulically or pneumatically generated force, a tensile force on the support rod 76A on the leg B are transferred, provided that the leg B is fixed to the support bar 76A with the foot cuff 76F. It is also possible to generate an extension force with weights or dead weights, as in FIG. 6 explained in more detail.

In Figure 8A is another development of the system according to the FIGS. 1 and 3 outlined. In the system 90 for the pre- and post-treatment of hip joint patients, as in Figure 8A shown is a variant of the drive from the FIGS. 7A and 7B shown. The construction shown essentially shows that in FIG. 7A shown construction. The patient P lies on a support element 91. The leg B to be treated rests on a further support element 93. The support element 93 is designed, for example, as a table, with table legs with rollers 93L. A support 93A is movably provided on a support surface 93B of the support member 93. A guide means 99 is similar to the guide means 79 in FIG Fig. 7A and 7B arched. A drive 98 is provided on the support 93A and becomes as in FIG. 7A and 7B moved with the support 93A. A retaining element 96 with a retaining bar 96A corresponds to the retaining element 76 and the element 76A FIG. 7A ,

In FIG. 8B becomes clear that unlike the training in FIG. 7A and 7B In this example, the drive 98 has a gear 98A that drives a toothed belt 99A. The toothed belt 99A is connected to the guide means 99. It runs over one or more pulleys 93C. By driving the gear 98A, the driving force of the driver 98 is transmitted to the timing belt and thus to the guide means 99. Thus, the rest 93A is moved in the plane of the surface of the table 93B. Again, a tensile force can be applied by means of the retaining element 96. In this case, an electric, a pneumatic or a hydraulic drive can be used, as in FIG. 7A and 7B shown. It is also possible to provide a drive with springs or weights.

The FIG. 9 shows a further development of the system for pre and after care of hip joint patients according to Figure 8A , Identical elements are designated in both figures with the same reference numerals. In FIG. 9 the system 90 'is shown. The system 90 'is similar to the system 90 Figure 8A , In the Figure 8A couch 91 is shown in FIG. 9 Not shown. It is understood that the couch out Figure 8A for a system 90 'as in FIG. 9 shown, can be used.

In the system 90 'in FIG. 9 a table 93 'similar to the table 93 of Figure 90A is shown. The table 93 'can be placed on a couch 91 or on a corresponding support element such as a bed. In particular, the table can be pushed over at least part of the couch 91 so that a support plate 93B 'of the table is located above the lying surface of the lounger. The table 93 'is provided on its legs with castors 93L. The castors 93L are rotatable 360 °. Thus, the table 93 'can be moved up and positioned anywhere on a couch, a bed or a suitable support element. The castors 93L are lockable. Thus, the table 93 'can be locked in a certain position. The table 93 'may be height adjustable to the height of the couch 93 Figure 8A or to be adapted to the additional height of a lying on the couch 93 patients.

The table 93 'in FIG. 9 includes the platen 93B '. The support plate 93B 'is typically fixed to a frame. On the support plate 93B' is shown a support surface 93C '. This can be fixed relative to the support plate 93B '. In FIG. 9 the support surface 93C 'is similar in shape to a section of a circular ring. On the support surface 93C ', a guide means 99 is provided, the guide means 99 from the FIGS. 8A and 8B equivalent. The guide means 99 is in FIG. 9 formed in the form of a guide rail.

On the support surface 93C ', a support 93A' is provided. The support 93A 'can be moved on the support surface 93 along the guide means 99 in a guided movement. The support 93A 'may slide or roll along the guide means with a sliding roller. In addition, the support 93A 'may slide or roll on the support surface 93C'.

Similar to the previous embodiments, the patient P lies on a first support element 81. The leg B to be treated rests on a second support element 83. The second support element 83 comprises a support surface 83B, which is part of a table approaching the first support element 81 can be rolled. For example, the table is the same as the table Figure 8A shown. The table includes table legs with castors 83L. On the support surface 83B, a support 83A is movably provided. Again, pad 83A is optionally adapted to a shape of a leg. A guide means 89 is provided in the form of a guide rod. This guide rod 89 is formed substantially straight. It is in contrast to the guide means 79 off FIG. 7A and FIG. 7B in any case, not arched. A drive 88 allows movement of the support 83A along the guide rod 89. The guide rod 89 guides the support 83A substantially linearly in the plane of the support surface 83B. Thus, a suitable translational movement to the movement of the leg B of the patient P may be provided. The drive is in FIG. 10B explained in more detail.

In the FIG. 10B shown support 83A has in its front part a groove or slot 83L. A guide body 89A is provided on the rod 89. This guide body 89A has a pin 89B which engages with the slot 83L.

By moving the threaded rod, the guide body 89A is moved along the guide rod 89. Thus, by rotating the threaded rod, the support 83A with the resting leg B is also moved. The drive 88 is provided on the side of the table stationary.

In the Figures 11A and 11B is a further development of the system according to FIGS. 1 and 3 shown. The embodiment in the Figures 11A and 11B is similar to the embodiment shown in FIGS Figures 10A and 10B is shown. In the Figures 11A and 11B For example, there is shown a system 100 for the pre and postoperative care of hip joint patients which has an alternative drive as compared to the drives that comprise the FIGS. 7A . 7B . 8A . 8B . 9 . 10A and 10B are shown by way of example. Similar to the previous embodiments, the patient lies P on a first support element 101. The leg B to be treated lies on a second support element 103. The second support element 103 comprises a support surface 103B, which is part of a table. The table can be rolled up to the first support element 101. For example, the table is the same as the table Figure 10A shown. The table includes table legs with castors 103L. On the support surface 103B, a support 103A is movably provided. The overlay 103A is optionally adapted to a shape of a leg. A guide means 109 is provided in the form of a guide rod. This guide rod 109 is substantially straight. Another guide rod 111 is provided substantially parallel to the guide rod 109. The guide rods 109 and 111 guide the support 103A substantially linearly in the plane of the support surface 103B. Thus, a suitable translational movement to the movement of the leg B of the patient P may be provided. A drive 108 allows movement of the support 103A along the guide rod 109 and 111. The support 103A is not provided directly to the guide rod 109 and 111 in the present example, but is provided on another guide means 112.

In FIG. 11B is a cut out Figure 11A shown. The guide means 112 includes, for example, a frame 112R and a guide bar 112S. The guide bar 112S is provided substantially perpendicular to the two guide bars 109 and 111. The guide rods 109 and 111 are suitably connected to the guide means 112. For example, they pass guide rods 109 and 111 through the frame 112R. The support 103A is suitably connected to the guide rod 112S, so that the support 103A is movable by means of the guide rod 112S. For example, the support 103A is connected to the guide rod 112S at at least one point 112F with a suitable fastener. The movement by means of the guide rod 112S is indicated by the arrow 110P in FIG Figures 11A and 11B indicated. Again, the other movement (ie perpendicular to the first movement 110P) is indicated by the guide rods 109 and 111 by the arrow 108P. As a result, two directions of movement in the plane of the second support element 103 are indicated. The two directions of movement are perpendicular to each other in this plane. The two directions of movement indicated by the arrows 108P and 110P are decoupled by the structure used by means of the guide rods 109 and 111 on the one hand and the guide rod 112S on the other hand. For example, arrows 108P and 110P may be identified with x and y coordinates and coordinate axes, respectively. Thus, for example, within a rectangle given by the guide rods 109 and 111, selectively preselected coordinates can be approached on the support surface 103B. One can thus scan a right-angled coordinate grid. The guide means 112 may comprise a drive 110. In this case, the guide rod 112S can be driven by the drive 110. The drive 110 may be provided similar to the drive 108. The drive 110 is not moved by movement of the support 103A in the direction of arrow 110P by means of the guide rod 112S. However, the guide means 112 is moved on movement of the support 103A by means of the guide rods 109 and 111 with.

In Figure 11A is further, similar to the FIGS. 7A . 7B . 8A . 8B . 10A and 10B a foot cuff 106F shown. The foot cuff can be suitably attached to a support bar (not shown). For example, the foot cuff can be hung over the handrail. Furthermore, a drive can be provided. Thus, the support rod can be moved, for example, hydraulically or pneumatically. The direction of movement is indicated by the arrow 106P. Thus, a traction can be transmitted to the leg B by means of the drive, provided that the leg B is fixed to the support bar with the foot cuff 106F. It is also possible to generate an extension force with weights or dead weights, as in FIG. 6 explained in more detail.

The in the Figures 11A and 11B shown drives 108 and 110 can be controlled by means of at least one control and control unit, such as a computer. It is understood that such a control and control unit can be combined with all embodiments shown. The control and control unit can control each of the drives in all the embodiments shown. In this case, the control and control unit can be integrated into the system and, for example, combined with one or more of the drives, or as a separate unit that communicates via signal lines or wirelessly with the drives. It is also possible to use an external computer, such as a laptop, tablet PC or a suitable smartphone for control.

It is understood that the control and control unit monitors the forces occurring during the movement of the leg, both for the movement of the support and for the extension force. In this case, at least one or more of the drives may include a safety shutdown in connection with the control and control unit. If forces occur during the movement of the leg that exceed predefined tolerances and / or predefined maximum values, then the respective movement of the leg can be automatically switched off. Thus, the extension force can be relaxed and a movement of the leg either stopped immediately or the leg can be gently moved back to the starting position. Likewise, the safety shutdown may include an emergency button for the patient. If, for example, the patient feels the movement of his leg and / or the extension force as too stressful or painful, then he can manually switch off the respective drives and the associated forces. For this purpose, a security device, such as a Emergency stop switch, be provided. For example, the patient may get a separate emergency stop switch in hand or within reach. With the help of this emergency stop switch, the patient can thus independently bring about an emergency shutdown of the drives.

It is understood that in the embodiments described above features are not limited to these specific combinations and may also be possible in any other combinations.
