Definitions

• the present invention relates to a therapy and training device for positively guided knee joint movement with two lower leg receptacles arranged on a guide arrangement, which are connected via articulated devices to a transmission element of the guide arrangement which connects the lower leg receptacles to one another in a motion-coupled manner such that a pivoting movement of one lower leg as a result of Knee flexion triggers an opposite swiveling movement of the other lower leg.
• a therapy and training device of the type mentioned which has a cable as a transmission element to which the joint devices, which produce a connection to the lower leg receptacles, are connected.
• the articulated devices, which are coupled to each other via the cable, are guided in a horizontally arranged guide arrangement designed as a guide rail, which is arranged on the floor or on the ground on which the patient to be treated is also located. Therefore, the lower leg shots in the known therapy and training device are in operation above the steering devices.
• the present invention is therefore based on the object of proposing a therapy and training device of the type described at the outset which makes it easier for the patient to move the leg in the stretched position out of the stretched position in order to be able to continue the movement therapy.
• a lever is provided for connecting the lower leg receptacles to the joint devices, which lever brings about a restoring torque counteracting the direction of rotation of leg extension about a pivot point of the joint device in question.
• the type of articulation of the lower leg receptacles according to the invention ensures that not the entire weight of the leg in the extended position acts in a manner that stabilizes the extended position, but that at least a part of the lower leg accommodated in the lower leg receptacle is related to the Articulation pivot point of the articulation device causes a moment counteracting this stabilization position.
• the lifting of the leg in order to get at least slightly out of the extended position at the beginning of the bending movement of the leg is made considerably easier for the patient.
• the articulation devices are arranged on the guide arrangement in such a way that the articulation device which is assigned to the bent leg via the associated lower leg receptacle is elevated in relation to that articulation device which is assigned to the extended leg via the associated lower leg receptacle Position.
• the increased energy potential of the bent leg compared to the stretched leg can be used to enable the patient to move the stretched leg out of the stretched position.
• An advantageous embodiment of this solution according to the invention consists in designing the guide arrangement in such a way that it has an inclined guideway for the joint devices.
• the lower leg receptacles are arranged on the joint devices in such a way that the force axis of the extended leg is below a pivot point of the joint devices.
• the articulation devices are provided with a swivel radius limitation device in order to be able to precisely define the radian of the desired range of motion.
• a particularly advantageous embodiment of the latching connection is achieved if a connecting hinge pin designed as a latching pin is provided on the lower leg receptacles and is intended for engagement in a hinge eye of the joint device.
• FIG. 1 shows a therapy and training device in a side view
• FIG. 2 shows the therapy and training device shown in FIG. 1 in a front view
• 3 shows a joint device of the therapy and training device in an individual representation
• FIG. 4 shows a sectional view of the joint device shown in FIG. 3 according to the section line IV-IV in FIG. 3.
• the therapy and training device 10 has a guide track arrangement 11 with four guide rods 12, 13, 14, 15, which at their ends have stand parts 16, 17, the two clamping halves 18, 19 (see Fig. 2) have summarized to the guideway arrangement 1 1.
• the stand parts 16, 17 are feet 20, 21 and 22, which allow the therapy and training device 10 to be positioned between the legs of a patient, as shown in FIG. 1.
• each guide part 25 On both sides of the guideway arrangement 11, that is to say both facing the viewer of FIG. 1 and facing away from the viewer of FIG. 1, there is in each case an articulation device 23, 24, which has one on each of two guide rods 12, 14 and 13, 15 longitudinally displaceably arranged guide part 25 is connected to the guideway arrangement 11.
• Each guide part 25 has two longitudinal guides 26, 27 which, on the one hand, enable reliable guidance along the guide rods 12, 14 or 13, 15, and on the other hand prevent the articulated devices 23, 24 from pivoting away from the guideway arrangement 11.
• a transmission element designed here as a toothed belt 28 is provided, which is guided around the guide track arrangement 11 via two deflection rollers 29, 30 positioned laterally on the stand parts 16, 17.
• these have pivotably arranged drivers 31 on the articulation devices 23, 24, which receive the toothed belt 28 in a form-fitting manner and between them and the guide part 25 of the articulation device 23, 24.
• the positive engagement of the driver 31 becomes the toothed belt 28 secured by means of a compression spring, not shown here.
• the driver 31 can be pivoted about a driver axis 32 while overcoming the spring force. In this released position, it is possible to change the distance g of the articulation devices 23, 24 continuously, or to move them both by the same amount in one or the other direction along the guideway arrangement 11 while maintaining a desired distance g.
• lower leg receptacles 35, 36 are pivotally connected to the joint devices 23, 24 via lever arrangements.
• the left lower leg 32 of the patient shown in its outline contours is received by the lower leg receptacle 35 connected to the joint device 23 such that the left leg is in its flexed position.
• the right lower leg of the patient which is only represented by the course of the associated lower leg axis 33, is located in the lower leg receptacle 36 assigned to the joint device 24 such that the right leg of the patient is in its extended position.
• the joint device 23 When the left patient's leg is transferred from its flexion position to its extended position, i.e. when the left lower leg is pivoted relative to the associated thigh, the joint device 23 is displaced longitudinally to the right via the lower leg receptacle 35 and the lever arrangement 34. To the same extent, force-coupled via the toothed belt 28, the joint device 24, the lever arrangement 34 and the lower leg receptacle 36, the right patient's leg moves in the opposite direction from its extended position shown in FIG. 1 into the flexed position.
• the lever arrangement 34 is pivotally connected to the joint device 23, 24 via a connecting joint pin 38 inserted in a swivel eye 37 of the joint device 23, 24.
• the connecting joint pin 38 has a circumferential locking groove 39 into which a spring-loaded locking pin 40 engages.
• the connecting joint pin 38 is pressed into the locking groove 39 into the swivel eye 37 while overcoming the spring resistance of the locking pin 40 until the locking pin 40 engages.
• An insertion cone 41 formed at the end of the connecting joint pin 38 acts as a support.
• the locking pin 40 is counter to the
• the lever arrangement 34 is angled so that a weight G which acts from the lower leg receptacle 35, 36 via a receptacle connection 41 to a lever end 44 of the lever arrangement 34 causes a weight moment which multiplies the weight G by a lever offset h Lever arrangement 34 corresponds.
• the lever offset h can be made changeable.
• this moment acts to support the movement of the patient's right leg in FIG. 1 from its extended position, which coincides with an end point or dead position of the back and forth movement of the joint devices 23, 24 along the guideway arrangement 11.
• the lower leg receptacle 36 is connected to the joint device 24 via the lever arrangement 34 in such a way that the lower leg axis 33 is offset by an offset dimension v downward from the pivot point 45 of the joint device 24.
• the restoring force R which results from a stretching movement of the left Patient's leg over the toothed belt 28 and the lower leg receptacle
• the size of the restoring torque can be influenced by a variable configuration of v - for example by a corresponding design of the lever arrangement 34.
• the joint device 23 assigned to the bent leg is at a higher level than the joint device 24 assigned to the extended leg. This makes it possible to use the weight of the bent leg to support the movement of the extended leg from its extended position.
• the joint device 23 or 24 has a swivel radius limiting device 46 with two angular stops 47, 48 which can be changed in their relative position relative to the joint device 23, 24 and which cooperate with a stop pin 49 on the lever arrangement 34 and thus the swivel movement limit the lever arrangement 34 relative to the articulation device 23, 24.
• FIG. 2 also shows, in the present case the feet 20, 21 assigned to the left-hand stand part 16 in FIG. 1 are connected to the stand part 16 via rod pull-outs 50, 51 in assigned rod receptacles 52, 53.
