Description
Technical field
This utility model belongs to area of medical devices, relates to a kind of orthopaedics human foot simulation heavy burden testing fixture; This device is that a kind of can simulation under foot is in physiology loading conditions when standing carries out the human body heavy burden analog that CT or MRI scans the ankle state of an illness.
Background technology
At present, along with the development of Imaging Technology, CT, MRI are outstanding day by day for the diagnostic significance of clinical disease, all the more so at field of orthopaedics; But, during for ankle and foot deformity (as flatfoot, pes cavus, Hallux turn up) row imaging examination, keep enough normal foot to bear a heavy burden particularly important.Practice confirms, x-ray during Weight carrying position is easy to realize, but due to checkout equipment as, the restriction of CT and MRI machine itself, needs patient to get clinostatism inspection, therefore, requires that patient keeps the heavy burden of enough normal foot just to create difficulty.Current, clinical CT or MRI carrying out ankle and foot scans under major part can only be in non-weight bearing (or loosening) state and carries out, and makes doctor there is certain deviation unavoidably to the assessment of disease; As: for the patient of some pliability flatfoot, its arch of foot often just can subside in heavy burden situation, if only do the CT scan under release position, then may the evidence of missed diagnosis flatfoot and data, and then cause mistaken diagnosis, fail to pinpoint a disease in diagnosis.
There is clinical research once to adopt wood materials to make corresponding foot heavy burden analog, comprise the plantar pressure induction installation in load-bearing device body frame and front; Its load-bearing device body frame base and plantar pressure induction installation base form chute, have rope to be connected between the two; In the hollow cuboid bracing frame of heavy burden body frame rear, hang counterweight apply load, and by rope and fixed pulley tractive plantar pressure induction installation, make it fully to contact with vola, by pressure inductor display load reading, reached the pressure of body weight level by the weight controlling counterweight.Clinical practice shows, and said apparatus has the following disadvantages: (1) described device volume is huge, in addition suitable with body weight counterweight, therefore moves very difficult, in clinical practice work, be difficult to daily development; (2) for the patient that body weight is different, adjust plantar pressure by the mode changing counterweight, not only waste time and energy, and adjustability is poor, be difficult to accurately control.
Therefore, the designer of the application intends providing a kind of more light easy-to-use orthopaedics human foot simulation heavy burden testing fixture; This device can be in physiology loading conditions when standing, carries out CT or MRI and scan the ankle state of an illness by simulated patient foot.
