[0001] Myoelectric prosthesis
[0002] Object of the invention
[0003] The present invention relates to a myoelectric prosthesis, comprising an electromechanical hand with the possibility of opening and closing; a wrist turning unit and means for controlling said movements.
[0004] This myoelectric prosthesis has characteristics aimed at achieving independent control of the opening or closing movement of the hand and the wrist rotation, so that these movements can be performed simultaneously.
[0005] Field of application of the invention
[0006] This invention is applicable in myoelectric prostheses for upper extremities, equipped with an electromechanical hand and wrist turning unit.
[0007] State of the art
[0008] Currently there are myoelectric prostheses equipped with an electromechanical with opening and closing movement, and a wrist rotation unit, which work with two input channels (two electrodes) placed prior to electromyography study (EMG) in areas where the tone of the group Muscle is better.
[0009] So far two electrodes are used since the detection of the electrode location zones in the stump is complicated. In addition the component manufacturers train the manufacturers of the prostheses for the single assembly of two electrodes.
[0010] These electrodes are connected to a control unit that processes the signal that arrives. Depending on the type of contraction performed by the user (short or long), the system activates the opening and closing of the hand, or the rotation of the pronation or supination wrist. That is, with the same electrode the two functions are performed (opening or closing and pronation or supination).
[0011] Although the type of contraction needed may vary depending on the manufacturer of the prosthesis and according to the needs of each user; In a typical example, the system is mounted as follows:
[0012] • Electrode 1:
[0013] - Long contraction - hand closure;
[0014] - Short contraction - pronation (Wrist twist inward)
[0015] • Electrode 2:
[0016] - Long contraction - opening of the hand;
[0017] - Short contraction - supination (Wrist twist out)
[0018] Thus, mounting two electrodes limits the simultaneous movements that the user can perform. Specifically, the technical problem posed by these prostheses is that the user does not It can simultaneously perform the opening or closing movement of the hand, and the wrist turn.
[0019]
[0020] Description of the invention
[0021]
[0022] The myoelectric prosthesis object of this invention, being of the type mentioned above and included: an electromechanical hand with single or multi-articulated clamp function; a wrist turning unit, and a power supply; it has the particularity of comprising four input electrodes, arranged in the prosthesis in a manner suitable for the capture by each of them of a myoelectric impulse independent of the patient or user; being connected two first electrodes responsible for the opening and closing of the hand to a processor of the electromechanical hand; and two second electrodes, responsible for the movement of rotation of the wrist to a processor of a unit of rotation of the wrist.
[0023]
[0024] With these characteristics, the first two electrodes provide adequate signals to perform the opening and closing of the hand; and two second electrodes, provide adequate signals for wrist rotation (pronation and supination).
[0025]
[0026] Users with capacity for this can use the four electrodes independently or in a combined way, combining the movement of wrist rotation with the movement of opening and closing of the hand in a very natural and simultaneous way, which results in a substantial improvement in comparison with current prostheses of this type.
[0027]
[0028] Therefore, in the myoelectric prosthesis of the invention with four input channels, the movements of opening and closing of the hand and the movements of rotation of the wrist are totally independent, and can be carried out individually or simultaneously.
[0029] Although it is not the object of the invention, it should be mentioned that the positioning of the electrodes in the prosthesis to obtain four differentiated signals is achieved in a high percentage of patients by means of an EMG study, regardless of the etiology of the amputation.
[0030]
[0031] Description of the figures
[0032]
[0033] To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
[0034]
[0035] - Figure 1 schematically an elevation view of an exemplary embodiment of a myoelectric prosthesis according to the invention.
[0036]
[0037] Preferred Embodiment of the Invention
[0038]
[0039] In the example embodiment shown in the attached figure, the myoelectric prosthesis (1) comprises; an electromechanical hand (2), with single or multi-articulated clamp function; a wrist turning unit (3) and a power supply (4).
[0040]
[0041] The myoelectric prosthesis (1) comprises four input electrodes (21, 22, 31, 32) strategically placed to collect, each of them, a differentiated myoelectric impulse from the user or patient.
[0042] Two first electrodes (21, 22), intended for the opening and closing of the hand are connected a processor (23) of the electromechanical hand (2) and the two second electrodes (31, 32) destined for the rotation of the wrist are connected to a processor (33) of the rotation unit (3).
[0043]
[0044] The user at will, can independently use four channels to control the movement of opening and closing the hand, and turning the wrist, contracting the muscles of the area where the corresponding electrode is located, and can also perform in a way combined, or simultaneous, the movement of opening and closing of the electromechanical hand (2) and the rotation of the wrist.
[0045]
[0046] Thus, this prosthesis allows the wrist to rotate while opening or closing the hand.
[0047] Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
