Definitions

  • the present invention relates to an orthopedic ambulation aid device more particularly intended for patient children suffering from motor disorders, with a view to their gait rehabilitation.
  • orthopedic walking aid devices There are orthopedic walking aid devices. These devices include a base fitted with 4 casters ensuring good stability.
  • the document FR 3 027 514 A1 describes such a device.
  • the base is surmounted by a saddle support on which a custom-made or standard foam saddle can be mounted.
  • the saddle is very wide so as to spread the legs of the child.
  • the child advances, therefore supported by the saddle, the legs spread apart by the latter.
  • this position which is intended for rehabilitation generates friction between the legs of the child and the saddle; these frictions hinder the child's walking and the skin of his legs is quickly irritated or even burned by the friction, which is a source of great discomfort.
  • the saddle does not maintain the patient's hips in position because the patient still has the freedom to spread the legs beyond the width of the saddle.
  • the saddle therefore does not prevent the poor positioning of the patient's knees and calves, which leads to vicious attitudes during learning / re-education of walking.
  • the child has the bust held in a tailor-made corset, secured to the saddle; the set must be changed regularly according to the growth of the child which is expensive.
  • the document JP 2007 14698 A1 describes a walking aid which allows the patient to pass from the standing position to the sitting position.
  • This device has leg supports that support and guide the legs of the patient.
  • the spacing of the patient's legs is obtained by the spacing of the stakes, which are mounted on a belt attached to the patient's hips.
  • the patient's hip spacing is not adjustable.
  • forces are exerted directly on the patient's spine when walking.
  • the document ES 2 609 248 A1 describes a walking aid device which does not include a saddle but two leg guardians.
  • the spacing of the patient's legs at hip level is obtained by means of two adjustable cushions which push more or less on each of the patient's hip joints so as to allow the correct positioning of the patient's hips during walking.
  • the patient's weight being taken up only at the level of the leg supports, forces are exerted on the patient's spine during walking, due to the weight of the patient's trunk, which is not taken up by the guardians.
  • the object of the present invention is to propose an orthopedic walking aid device which overcomes all or part of the drawbacks linked to the aforementioned devices of the prior art.
  • the present invention relates to an orthopedic walking aid device of the type comprising a base fitted with rollers, a saddle support surmounting said base and extending substantially vertically and along the length of said base, and possibly a saddle mounted on said support. saddle and whose two blanks are substantially vertical.
  • said device comprises on each side of said saddle support, an articulated arm, which comprises a first segment whose first end is mounted for rotation on said device around a first horizontal axis of rotation and perpendicular to said longitudinal direction of said base and the second end of which is mounted for rotation about a second axis of rotation parallel to said first axis, on the first end of a second segment, the second end of said second segment comprises a wedging piece mounted in rotation around a third axis of rotation parallel to said first axis and capable of receiving and locking the leg, knee, ankle or foot of said patient and said wedging piece is mounted adjustable in position on said second end of said second segment, depending on the width of said device.
  • the wedging piece can therefore be more or less separated from said device according to the width of the latter and locked in position according to the width of said device.
  • the wedging piece allows the patient's legs to be spread without having to use a wide saddle.
  • the articulated arm accompanies the movement of the patient's legs and keeps them in the axis of the device and spread apart on either side of the latter.
  • the spacing of the legs maintained by the wedging pieces keeps the patient's hips in position; in fact, the latter can neither spread his legs further, nor bring them together, which blocks his pelvis and avoids vicious attitudes during gait rehabilitation, especially at the knees. Since the patient's body can be supported by the saddle mounted on the saddle support, the weight of the patient's trunk is taken up by the device at the saddle support, which eliminates any transmission of forces to the patient's spine.
  • the wedging piece therefore also makes it possible to orient the leg without hampering walking and thus avoids vicious attitudes.
  • the wedging piece can be adapted to wedge the calf, shin, thigh, ankle or foot of the patient.
  • the position of the articulated arm is adapted accordingly.
  • the wedging piece can be mounted on the front of the lower limb (for example on the shin) or on the back (for example on the calf).
  • the device When the device includes a saddle, it can be made to measure or in series with possibly several ranges depending on the morphologies and size of the patients.
  • the presence of articulated arms makes it possible to equip the device with a common series saddle for several patients because the correction is carried out by the articulated arms and not by the saddle, as in the devices of the prior art.
  • the saddle preferably has substantially vertical blanks and it is narrower than the distance between the two wedging pieces so as not to modify the spacing of the patient's hips fixed by the wedging pieces.
  • said articulated arm comprises return means which exert a return force directed towards one end of said base and / or vertical and oriented towards said saddle support.
  • the end of the base corresponds to the front end in the patient's direction of travel.
  • These return means can be springs, pneumatic or hydraulic pistons or small motors.
  • the device further comprises means for exerting a force aimed at aligning said first and second segments of said articulated arm along their length.
  • These means make it possible to help the patient during the extension of the leg during walking. They can be springs, hydraulic or pneumatic pistons or small motors.
  • said first end of said first segment is rotatably mounted on said saddle support.
  • a mounting piece must be provided which also makes it possible to adjust the position of the arm along the device.
  • the first segment can be provided with a plurality of perforations which allow it to be fixed to the device, in particular to the mounting piece and thereby the variation of its functional length for the articulated arm.
  • said first end of said first segment is rotatably mounted on a connecting piece integral with said base.
  • This part may include a ring which is slid on the base and thus allows the attachment of the arm. It is thus possible to adapt a device of the prior art of the above-mentioned articulated arm. The position of the arm along the device is thus easily adjustable.
  • the first segment of the arm may also include a plurality of perforations allowing its fixing and the adjustment of its length.
  • said articulated arm can be mounted adjustable in position according to the length of said device. This allows you to adjust the position of the arm so that the wedging piece can be attached to different places on the patient's leg, for example, the thigh or calf or even the ankle.
  • the return means are not limited according to the invention. They may include a first spring or a first motor which substantially connects said second end of said first segment to said saddle support or to said base and a second spring or a second motor which connects said segments.
  • the force exerted by the springs is adapted to the patient.
  • the springs can thus be easily changed and exert a restoring force adapted to the patient.
  • the return means comprise on each articulated arm two motors and a spring or 3 motors and no spring.
  • said wedging piece is mounted adjustable in position according to length of said segment. It is thus easy to adapt the size of the device to the morphology of the patient.
  • the wedging piece may include links capable of being fixed to a shoe of said patient so as to maintain the foot of said patient in a position substantially perpendicular to his calf.
  • the width adjustment of the wedging elements makes it possible to properly adapt the device of the invention to the morphology and handicap of the patient and therefore to adjust the spacing of the legs and the hips.
  • the links make it easier for the patient to walk, as explained later.
  • the length of said first segment and / or of said second segment is adjustable.
  • This adjustment can be obtained by means of a plurality of perforations equipping the segment considered.
  • the length between the attachment point of the segment and its second end is varied, and therefore the useful length of the latter.
  • the depth of said saddle support measured along the length of said device is adjustable, in particular by sliding.
  • This adjustment can be implemented by means of two sliding profiles, one inside the other, the relative position of which can be fixed.
  • said saddle support is mounted adjustable in height on the device and in particular on the base. It is thus possible to adapt the device according to the size of the patient but also his handicap. Indeed, some patients cannot extend the leg due to muscle retractions and it is then necessary to rehabilitate them when walking in a semi squatting position. Once the muscles have been able to lengthen, the device can thus be adapted to the new possibilities of the patient who gradually manages to extend the leg. By adjusting the position of the saddle holder at a greater distance above the base, one can continue to support the patient's trunk weight without altering the gait rehabilitation while respecting the limits of flexion / extension of the lower limbs of the patient .
  • the device When the patient has made good progress in walking, the device can be used to support the weight of the patient's trunk, which is held upright on either side of the saddle of the device of the invention. It can also be used with the saddle lowered, the patient standing: in this case, the device no longer provides support for the weight of the patient's trunk which allows him to perform an even different rehabilitation.
  • said saddle support comprises means for holding the bust of said patient which are optionally adjustable in height and / or in width and / or tiltable towards one and / or the other of the ends of said device.
  • These retaining means may include compression straps for restraining the patient on the retaining means.
  • These holding means can be vertical bars mounted adjustable in height on the front and rear portions of the saddle holder and equipped with horizontal plates extending along the width of the device.
  • the rear portion of the saddle support is mounted tiltable in the direction opposite to the portion front of the saddle support.
  • This tilting rear portion makes it possible to facilitate the installation of the patient on the device of the invention and to maintain it precisely on the device in order to avoid the vicious positions when walking.
  • the saddle support is mounted tilting about an axis parallel to the width of the device so that it can be lifted in the direction opposite to said base.
  • This adjustment can be obtained by means of plates as described later.
  • said wedging piece comprises a sole fitted with a vertical wedging portion of the heel of said patient's foot.
  • a wedging piece is able to cooperate with the patient's foot to block it, in particular along the width of the device.
  • the sole is advantageously a metal plate 3mm thick covered with a layer of rubber for grip.
  • the wedging part of the heel is vertical and integral with the sole.

  • the bottom bar 32 is integral with a front bar 33 and a rear bar 34.
  • the front bar 33 is secured to the external beam forming the bottom bar 32 while the rear bar 34 is secured to the internal beam of the bottom bar 32, which internal beam slides in the aforementioned external beam.
  • the bottom bar 32 and the front and rear bars 33 and 34 form a U open upwards, in the direction opposite to the base 1.
  • the front bar and the rear bar 33, 34 have transverse plates 330 (only one is referenced on the Fig. 1 , for the sake of clarity of the figures) and 340 on which the patient's bust can come to bear.

  • the first spring 71 therefore connects the fixing tab 561, 563 to the second end of the first segment 52.
  • the second spring 73 connects the second end 512 of the first segment 51 to substantially the second end 522 of the second segment 52.
  • the trajectories of the elements of the articulated arm 5 are identical to those shown with reference to the first mode of production.
  • the first spring 71 exerts a restoring force directed towards the front of the device and towards the saddle support 3.
  • the second spring 73 exerts a restoring force directed towards the rear of the device and towards the saddle support 3.
  • the device of the invention is adapted to the size of the patient and / or his handicap.
  • a saddle (not shown) which comprises two substantially vertical blanks which extend on each side of the bottom bar 32.
  • the position of the wedging element is adjusted 53 depending on the width of the device so as to spread the legs of the patient when he is installed astride the saddle.
  • the wedging element 53 is pulled down to bring it into the low position B1 of the minor axis of the ellipse E1.
  • the wedging element 53 is fixed to the calf of the patient (on each side of the device). In this position, the patient's feet are on the ground, legs apart so that there is no friction between the patient's thighs and the saddle.
  • the patient's bust is held by the aforementioned holding means, which are also adjusted beforehand to its size.
  • the rear portion 34 of the saddle holder 3 is pivoted so that it is horizontal. The patient is then easily installed by sliding him on the saddle, from the back of the device.
  • the springs 71 and 73 exert an upwardly oriented vertical force which tends to lift the patient's feet, thereby helping him to walk and facilitating propulsion. These springs also exert a force directed towards the front of the device which tends to help the patient to put his leg forward, thus helping him to walk.
  • the patient lifts a foot, helped by the means of recall; his knee bends and his foot (and therefore the wedging piece 53) describes the rear portion of the ellipse E1, in the direction of the arrow F1, up to the high position H1.
  • the wedging element 53 When the wedging element 53 is in the high position H1 of the minor axis of the ellipse E1, the patient rests his foot on the ground by exerting a force on the springs 71 and 73 which makes it possible to build muscle.
  • the wedging piece 53 then describes the front part of the ellipse E1 according to the arrow F2.
  • the force exerted towards the front of the device by the return means also helps the movement of the patient's leg. This movement is also helped by gravity. The patient thus manages to move, carrying the device with him thanks to the articulated arm 5.
  • the wedging elements 53 can also include eyelets through which passes a link capable of being fixed on a shoe of the patient.
  • This link makes it possible to keep an angle formed by the patient's foot and leg when the patient is walking.
  • This link (one on each side) prevents the patient's foot from aligning with the leg and prevents him from placing his foot properly on the ground.
  • the saddle holder 3 is mounted adjustable in position according to the height of the vertical beam 17. It can thus be more or less close to or distant from the base 1 and allow the device to be adapted to the size of the patient and the evolution of his handicap. The device can even then serve as a walking aid without supporting the patient's weight when the patient has already progressed well.
  • Rails can be used to form the segments of the articulated arms 5.
