A quick measuring instrument for ankle joint activity angle

Abstract

The invention discloses a quick ankle joint moving angle measuring instrument which comprises a frame type base. The outer ends of the two sides of the base are each provided with a dial plate support in a welding mode. An angle dial is arranged on each dial plate support. The middle of the frame type base is provided with a human body bearing plate. The outer ends of the two sides of the human body bearing plate are each provided with a bearing shaft. The bearing shafts are sleeved with shaft sleeves. The upper surfaces of the shaft sleeves are fixedly provided with measuring plates. The measuring plates are fixedly provided with right-angle pointers. The transverse edge end points of the right-angle pointers are aligned with the circular center positions of the corresponding angle dials. The vertical edges of the right-angle pointers point to the scales of the angle dials. The quick ankle joint moving angle measuring instrument is short in measuring time and high in measuring accuracy, the working efficiency of doctors is improved, measuring can be conducted without taking off shoes, the opportunity that the doctors examine patients with hands is reduced, the safety of the patients in the process of seeking medical advices is guaranteed, and the instrument has a social meaning in interrupting transmission of potential diseases.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a quick measuring instrument for ankle joint activity angles. Background technique [0002] The main activities of the human ankle joint are dorsiflexion and plantarflexion. When the ankle joint is affected, it mainly affects its dorsiflexion and plantarflexion activities. For some foot and ankle diseases, the change of the ankle joint angle before and after treatment is an indicator for judging the effect of treatment. The changes in the range of motion of the joints obtained by regular physical examination of healthy people are the indicators to understand the health of the human body. [0003] At present, the clinical measurement of ankle plantar flexion and dorsiflexion angles in hospitals requires the subject to take off his shoes and lie flat on the examination bed, and the doctor uses a goniometer to measure with bare hands. Due to the error of human factors, there ar...

Problems solved by technology

However, the method adopted by this technical solution is still the way that the whole body of the human body is tilted forward or backward, which cannot overcome the influence of factors such as human body weight, range of motion of the cervical or thoracic spine, and lumbar mobility on the ankle joint, making the measurement results inaccurate and validity
