Definitions

  • the invention relates to a hand orthosis for bending and / or stretching at least one finger of a patient's hand, with a force introduction means which can be coupled to at least one finger segment assigned to a finger of the patient's hand. Further disclosed is a module member for a finger segment of a hand orthosis and a fastening means for a hand orthosis.
  • Orthoses are already known from the prior art and are used in particular - usually as passive splints - in patients in whom, for example, after a stroke neurological deficits appear, which is associated with a spasticity of the fingers or the hand.
  • the orthoses can counteract the spasticity.
  • Dynamic rails are also known from the state of the art, by which - for example, after injuries of the flexor tendons of the hand - movement deficits and possibly a renewed tearing of these tendons to be prevented in the healing phase by the affected finger, for example, by an elastic band in a bent Attitude is fixed. The patient can then do the Move finger against the restoring force of the band.
  • In the treatment of stroke patients are also stationary hand-held robot used, for example, from the US 8,574,178 B2 are known.
  • the US 5,178,137 discloses a hand orthosis according to the preamble of claim 1.
  • the document shows an orthosis, the finger segments of which are formed of outer and inner module members, which can be pivoted against each other. By a spindle drive can thereby bend the finger segment and stretch.
  • an orthosis is known whose finger segments are made up of individual module links coupled together by a chain. By connecting the module members to the chain, it is possible to adjust the axial distance of individual module members relative to each other.
  • the DE 201 13 431 U1 shows a glove with stiffening strips which are mounted on the glove, for example, to provide increased stability in a goalkeeper glove. An active adjustment of the module members does not take place here.
  • the known hand orthoses which are commonly used to treat stroke patients having only limited control of the affected hand or insufficient muscle activity to deploy the affected hand, are unable to provide the patient with the affected hand enable. In these cases, the patient is then, despite the provision of a hand orthosis not able to take objects safely with the affected hand, so that even the opening of a bottle and other simple activities of everyday life are very cumbersome and thus the quality of life of the patient adversely affected.
  • the hand orthotic part of the present invention is therefore based on the object to reduce the disadvantages mentioned above and to provide a hand orthosis, which simulates the anatomy of the human finger and at the same time provides an individual adaptability to the fingers of a patient's hand.
  • the Handorthese part of the problem is solved by a hand orthosis according to claim 1.
  • the module members each have at least one latching member and at least one latching seat for receiving a corresponding latching member of an adjacent module member.

  • the latching connection from the Detent member and the locking seat at the same time forms a hinge connection.
  • the joints necessary for bending and / or stretching the finger can be realized.
  • the arrangement of the locking seats in a region which essentially corresponds to the physiological position of the ankle rotation axes, the functionality of the hand orthosis according to the invention can also be improved.
  • a stiffening means for local stiffening of the finger segment is provided.
  • a receptacle for the stiffening means is formed in the finger segment and there in the individual module members.
  • the stiffening improves the functionality of the finger segment.
  • the stiffening means may for example be formed as a wire which is inserted into the receptacle. In the context of the invention, however, it is also possible that adjacent module members are firmly connected to each other by a screw connection. Alternatively, it is also provided that the stiffening means is designed as a stiffening comb, the tines can be secured in correspondingly shaped recordings in the finger segment, and Although preferably clipped. In this context, it has also proven to be advantageous if the receptacle is formed on the side facing away from the finger of the module member.
  • the finger segment is assigned a guide receptacle for receiving a linear guide.
  • the linear guide is associated with a finger, it is thereby possible to couple the finger segments of the hand orthosis with the finger so that a linear guided relative displacement between the finger and the finger segment is possible to compensate for the change in length of the finger.
  • the guide receptacle is formed in the module member.
  • a coupling means is provided for coupling the linear guide with the finger segment or the module member.
  • This coupling means can cooperate, for example, with a slot of the linear guide. Due to the slot-shaped design, in addition to the coupling of the finger segments with the patient's hand, in particular a limitation of the relative adjustment between the finger segment and the linear guide can be achieved. At the same time, it is also ensured by the linear guide that only one adjustment in one direction.

  • the linear guide is associated with a support base through which the force transmitted to the finger is evenly distributed.
  • the support base can be formed in particular concave and thereby nestle particularly well on the finger.
  • the at least one force introduction means is selected from a group that includes electric drives and elastic return elements. While elastic return elements - such as springs - are particularly preferred in those cases in which the patient is able to move the fingers of his hand equipped with the orthosis in one direction, so either to bend or stretch, and thus only the Support in the other direction is required, an electric drive, which may for example be designed as a servomotor or as a servomotor, indicated in those cases in which the patient is neither able to bend the fingers of the hand or stretch , In the context of the invention, it is also provided in particular that each finger segment is assigned its own force introduction means. However, within the scope of the invention it is also conceivable for a force introduction means to act on several finger segments together in order to bend and / or stretch them together. It is also possible to couple several fingers at once with one finger segment.
  • the force introduction means is connected to a finger segment by at least one pull-pressure element in such a way that bending and / or stretching of a finger connected to the finger segment by the finger Force introduction is possible.
  • a particularly simple way is given to ensure the bending and / or stretching of the fingers connected to the finger segment by tensile or compressive forces are transmitted to the finger segment by the force application means.
  • a train-pressure element is designed both for the transmission of tensile and compressive forces.
  • two train pressure elements are kept available, one of which transmits tensile and the other pressure forces from the force generating means to the finger segment. Due to the tensile force can be stretched a bent finger and the pressure force is ultimately bent a stretched finger, but in the context of the invention, the reverse application of force is possible.
  • the tension-compression element has sufficient flexibility to be able to be adjusted by the force introduction means and at the same time be able to follow the movement of the finger can. It has also proven to be particularly useful when the pull-push element is attached to the distal end of the finger segment. Thus, an associated finger of the patient's hand can be easily bent or stretched, as this improves the lever acting on the finger.
  • a suitable material for the tension-compression element may contain, for example, nitinol.
  • the module member has at least one bushing for the tension-compression element assigned.
  • the train-pressure element can be guided in the module members and is thus protected in particular from damage.
  • this also allows a very low height of the module members reach, which in turn has a positive effect on the comfort of the hand orthosis.
  • the at least one force introduction means can be activated by a control pulse of a pulse generator.
  • a control pulse By a suitable control pulse, the bending or stretching of the patient's fingers and thus the opening and closing of the patient's hand can be controlled.
