Definitions

  • the present invention relates to a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand; a finger movement splint for carrying out such a movement with such a length adjustment device and a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one such finger movement splint.
  • the present invention also relates to a method for adjusting the length of a finger movement splint on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand.
  • Therapy devices with finger movement splints for the automated movement of individual and/or multiple fingers of a hand enable controlled joint mobilization regardless of the availability of physiotherapy staff. Through automated training that is independent of the time of day and individually tailored to the respective user, such devices improve the success of therapy in a cost-effective manner and shorten the user's recovery time.
  • JP 2011 115 248 A and in the US 2014/028 86 64 A1 Devices for supporting finger movement are disclosed, the movement mechanism of which is arranged laterally next to the respective fingers, so that movement restriction by resting on the finger is avoided.
  • the JP 2011 115 248 A discloses a device for supporting a movement, in particular a finger movement splint, which is said to be able to set a three-joint region to a natural bent position.
  • a finger movement support device which uses sensor technology to determine the user's intention regarding a desired finger movement ("bending or stretching") and then supports this movement with the help of piezoelectric drives arranged on each finger joint.
  • both devices can only be inadequately adapted to the differentiated anatomical shapes of the fingers or thumbs of different patients, which means that the automated movement of the fingers performed by them can deviate relatively significantly from a natural movement.
  • a portable exoskeleton training robot for hand rehabilitation has become known.
  • This training robot includes a fixation device for the hand, which can be attached to the back of the hand and the wrist, and rehabilitation devices for the fingers and thumb.
  • the rehabilitation devices are each driven by linear motors.
  • Threaded rods are available which allow at least manual length adjustment for each individual rehabilitation device.
  • the EN 11 2017 000 012 B4 a therapy device for carrying out a continuous, passive and/or actively assisted movement of the fingers and thumb of a patient's hand, which allows each selected finger to be provided with its own finger movement splint with movement kinematics, which are arranged laterally to the finger to be treated and provide it with a allows for unrestricted bending and/or stretching movements.
  • the well-known finger movement splint is based on a slide-rail movement kinematics, which enables an automated finger movement that is very close to an anatomically natural finger movement.
  • a finger movement splint or a therapy device is described, the movement kinematics of which include a multi-joint hinge as a means of bending a metacarpophalangeal joint and is therefore particularly robust against the effects of axial forces and torsional forces on the finger movement splint.
  • the movement principles of both of the aforementioned publications are hereby expressly referred to in full.
  • the device in particular the individual finger movement splints, must be adjusted to the respective anatomy, i.e. to the hand size and/or the individual finger dimensions, before training begins.
  • the individual finger movement splints are usually attached manually to the upper shell or holder of the respective therapy device in the optimal position for the respective user.
  • the finger movement splints must then be manually removed after a training session and manually reattached in a different place for the next user. This procedure is time-consuming and, in everyday clinical practice, adversely reduces the training time available to the respective user with the therapy device.
  • the object of the present invention is therefore to provide a device or a method which carries out the adaptation of a finger movement splint or a corresponding therapy device to the anatomy of the respective user quickly and cost-effectively in an automated manner.
  • a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 1; by a finger movement splint for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 11; by a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 12; and by a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 14.
  • the carriage can preferably be operatively connected directly to the drive.
  • the carriage can also be operatively connected indirectly to the drive via at least one connecting element.
  • An embodiment in which the carriage can be operatively connected directly to the drive, in particular via a direct operative connection to a spindle of the drive, enables a comparatively simple construction of the length adjustment device, whereas an embodiment in which the carriage can be operatively connected indirectly to the drive via at least one connecting element promotes a comparatively compact, in particular flat construction of the length adjustment device.
  • the adjustment rail is preferably a grid track with at least two grid elements.
  • a grid track with at least two grid elements advantageously enables the holding means and thus also the finger movement rail to be locked onto the therapy device in a simple manner.
  • the at least two grid elements protrude from the plane of the adjustment rail in a substantially wedge-shaped (triangular) and/or semicircular and/or in the form of a circular arc triangle (so-called "Reuleaux triangle”).
  • Grid elements that protrude from the plane of the adjustment track in this way advantageously enable positive locking, whereby in the case of a wedge (triangular) shape and/or a semicircular shape and/or the shape of a circular arc triangle (so-called "Reuleaux triangle shape”) the effect of the blocking mechanism can be overcome more easily (with less effort) by exerting force using the slide than would be the case, for example, with grid elements that protrude from the plane in a cuboid shape.
  • the at least two grid elements can also be designed as holes within the adjustment rail.
  • An adjustment rail with holes as grid elements in the sense of a perforated plate advantageously enables a flatter construction of the adjustment rail.
  • the holding means preferably has a first side wall for holding the blocking mechanisms and a second side wall for holding the finger movement rail, which are connected to one another at least via a base element, thereby forming a substantially U-shaped cross section through which the adjustment rail runs.
  • a substantially U-shaped holding means advantageously enables simple and cost-effective production, depending on the material selected, for example by bending a metal sheet, by injection molding or 3D printing. In addition, such a holding means can easily be moved along the adjustment rail as a guide.
  • the adjustment rail comprises a first side wall and a second side wall along its longitudinal axis, wherein the first side wall, the adjustment rail and the second side wall together form a substantially U-shaped cross section, and wherein the holding means is arranged to be movable within the substantially U-shaped cross section with respect to the adjustment rail.
  • the blocking mechanisms each comprise at least one fixing means arranged on the holding means, preferably on the first side wall; a blocking lever pivoted on the holding means, preferably on the first side wall, via a rotation axis; and a means for springing the blocking lever relative to the fixing means, wherein the blocking lever is designed such that when the carriage comes into operative connection with the blocking lever, the blocking lever is rotated from a blocking position to an unblocking position and the holding means is thereby movable in at least one direction.
  • a blocking mechanism advantageously enables a change in position of the holding means caused by the carriage and thus the drive of the finger movement rail and the the finger movement rail held by the holding device along the adjustment rail on the therapy device.
  • the blocking mechanisms can also be designed as a single piece and made from a resilient material, in particular spring steel and/or hard rubber.
  • the fixing means and the blocking levers can advantageously be made from a single piece of resilient material, with the blocking levers being arranged at an angle to the fixing means and the intersection points between the blocking levers and the fixing means corresponding to the axes of rotation.
  • the means for suspension can be replaced by the spring properties of the resilient material, in particular the spring steel and/or the hard rubber, itself, which advantageously saves one component per blocking mechanism and reduces the size of the blocking mechanism.
  • the blocking levers are operatively connected to the adjustment rail in their respective blocking position, in particular to the grid elements of an adjustment rail designed as a grid track, and in their respective unblocking position are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track. If the blocking levers are operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, a movement of the holding means along the adjustment rail is advantageously prevented and the finger movement rail is held stable and securely in one position so that the therapy movement can be carried out safely.
  • the holding means can advantageously be moved along the adjustment rail to any position or, in the case of an adjustment rail designed as a grid track, to a position depending on the grid elements or the holes.
  • the present invention also relates to a finger movement splint for performing a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand, comprising a length adjustment device according to one of claims 1 to 10.
  • the present invention also relates to a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one drive for a finger movement rail and at least one finger movement rail according to claim 11.
  • the drive is a linear drive, in particular a spindle motor, a pneumatic cylinder, a hydraulic cylinder and/or a cable pull.
  • a linear drive advantageously enables a controlled movement of the carriage and thus both the finger movement rail during the execution of the therapy movement and the holding means together with the finger movement rail during length adjustment along the adjustment rail.
  • the present invention relates to a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, which is characterized in that a connecting element of a finger movement rail arranged on a holding means is moved with the aid of a drive via a carriage along an adjustment rail from an amplitude for a therapy movement into a first or second adjustment range; wherein the carriage, when moved by means of the drive in a first direction along the adjustment rail into the first adjustment range, exerts a force on the first blocking mechanism upon contact with a first blocking mechanism, so that the first blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the first direction, and wherein the carriage, when moved by means of the drive in a second direction along the adjustment rail into the second adjustment range, exerts a force on the second blocking mechanism upon contact with a second blocking mechanism, so that the second blocking mechanism is released and the holding means together with the finger
  • a length adjustment device advantageously makes it possible to automatically move a finger movement rail along an adjustment rail using the drive already present for the finger movement rail on a therapy device and to fix it in a desired position - depending on the finger length or hand size/length of the user - on the adjustment rail and thus on the therapy device in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or thumb of a hand in a stable position.
