The working principle of the invention is as follows:
the first step is that the operator first assembles the various components of the device normally and then uses the device normally.
And a second step of: firstly, a patient lies on a treatment bed for nuclear magnetic resonance examination, the palm of the hand is upwards, five fingers sequentially pass through five fixing rings 32 respectively to be kept fixed, at the moment, the patient gradually contracts the fingers of the patient to hold a fist and controls the palm to open, during the process of the fist grasping of the patient, a plurality of fixing rings 32 drive a connecting rope II33 arranged at the outer side of the connecting rope II and an arc-shaped bracket 35 to synchronously move towards the center position of a central elastic ring 4, at the moment, the connecting rope II can carry out a vertical and outward pulling force on the middle part of a main acting rope 2, thereby pulling the main acting rope 2 to transversely stretch, ensuring that an even attaching effect is kept between the arc-shaped bracket 35 at the other side of the main acting rope 2 and the main acting rope 2 all the time, ensuring that the main acting rope 2 is always stretched in an arc shape, and the connecting rope II is not stretched to form a V shape to cause the problem of uneven force, at this time, a weak resistance is provided for the fingers of the patient by the transverse deformation of the main acting rope 2 (when the external force is perpendicular to the middle part of the main acting rope 2, the deformation can be completed only by weak force when the external force is stretched, and when the acting force is parallel to the central axis direction of the main acting rope 2, the external force is applied to the whole main acting rope 2 to stretch the main acting rope 2, the characteristics are the deformation characteristics of the main acting rope 2), when the palm of the patient is opened, the plurality of fixing rings 32 drive the connecting ropes I31 and the arc plates 34 arranged on the inner sides of the fixing rings to synchronously move towards the direction away from the center of the center elastic ring 4, at this time, the arc plates 34 fixed on one ends of the connecting ropes I31 gradually push the center elastic ring 4 outwards to deform, and the acting force direction is also perpendicular to the outer side of the center elastic ring 4, at this time, five fingers synchronously act inside the center elastic ring 4, the central elastic ring 4 provides micro resistance to the fingers of the patient, and the auxiliary rope 6 between the fixing rings 32 fixed by the little finger and the thumb can generate length change along with uneven force between the little finger and the thumb in the process of stretching the fist and the palm of the patient, namely the auxiliary rope 6 can slide left and right in the sleeve ring 7, so as to change the lengths of the auxiliary rope 6 positioned at two sides of the sleeve ring 7, thereby correlating the little finger and the thumb in the movement process, further balancing the problem of uneven force on the fixing frame 1 caused by overlarge space between the little finger and the thumb (because of the distribution characteristics of the fingers of the human body, the space between the other fingers is almost equal, and the little finger and the thumb can keep larger space in the process of stretching the fist and the thumb, the existence of the space can influence the uniformity of the acting force of each finger to the peripheral fixing frame 1), in the sliding process of the auxiliary rope 6, the loop 7 and the compensation rope 8 fixed on one side of the loop can be continuously acted, as the compensation rope 8 is in a tightening state, under the tightening state, the change of the auxiliary rope 6 can influence the continuous stretching or outward contraction recovery of the compensation rope 8 towards the center so as to balance the problem of uneven force caused by overlarge distance between the little finger and the thumb, in the reciprocating finger fist and opening process of a patient, the main acting ropes 2 and the central elastic ring 4 respectively carry out tiny resistance stimulation on the finger of the patient, the weak resistance can continuously carry out resistance stimulation on the finger of the patient in a motion state, and the motion stimulation of the hand is conducted and radiated to different brain nerve areas of the patient, so that different nerve areas of the patient are activated, thereby more accurately confirming whether the focus of the nerve-impaired patient invades the finger motion function area, the device provides a more accurate reference basis for the examination process, thereby achieving the aim of accurate examination, and finally, the device can be used for completing the process of effectively stimulating each nerve region of the finger and brain of a patient when the patient is subjected to nuclear magnetic resonance examination.
And thirdly, firstly, the operator normally closes the device, then the operator checks whether the fixity among the components of the device is normal, and then the parts with more serious ageing and abrasion inside the device are replaced and maintained.
