Embodiment Construction

[0026] see Figures 1 to 7As shown, the present invention provides a technical solution: a joint activity limiter of a human lower limb skeletal model, comprising a knee joint limiter 3 installed at the lower end of the femur model (2), a slider fixed at the top of the tibia model 1 4. The femoral end flexion and extension limiting ring 7 sleeved on the upper end of the femoral model 2, the femoral head connecting block 6 wrapped outside the femoral head model 21 and the hip joint limiter 5 installed on the acetabular model 8, the femoral The model 2 and the tibial model 1 are slidably connected within a certain range of angles through the slider 4 and the knee joint limiter 3. The hip joint limiter 5 is spliced ​​by the acetabular connection ring 51 and the acetabular end flexion and extension limiter ring 52. The femoral head model 21 can be connected to the acetabular model 8 through the femoral head connecting block 6 and the acetabular connecting ring 51 within a certain ...

Abstract

The invention discloses a joint movement degree limiter of a human lower limb skeleton model in the technical field of skeleton model teaching aids. The joint movement degree limiter comprises a knee-joint limiter body at the lower end of a thighbone model, a slider fixed to the top of a shinbone model, a thighbone end extension limiting ring sleeving the upper end of the thighbone model, a femoral head connection block with which the outer side of a femoral head model, and a hip joint limiter body installed on an acetabulum model. Through the three connection positions, the limiter simulatesthe real activity state of the human lower limb skeleton, more real and effective teaching and using are provided for students, and the students can clearly and very intuitively know the real activitystate of the lower limb joints; moreover, the students learn without crossreference of video animation and skeletons, erroneous understanding is avoided, the limiter is more intuitive and real, and erroneous understanding is not generated; by means of the limiter, personal errors generated when a teacher teaches are effectively prevented, and teaching is more accurate.

Description

technical field [0001] The invention relates to the technical field of skeletal model teaching aids, in particular to a joint activity limiter for a human lower limb skeletal model. Background technique [0002] In the field of medical teaching, teachers need to teach students the shape and proportion of bones, as well as the names and functions of each bone. Currently, teachers use pictures, videos, text and models to teach. All these teaching methods are only models. The teaching is the most intuitive and the easiest to see clearly, so now medical schools and even hospitals have human skeleton models for display. In the current skeleton models, the bones are generally connected by bolts, and the bones are fixed and locked. Activities, it is more standard to show the posture of the skeleton model that is not understood when standing, but it cannot be bent, which makes it very inconvenient during teaching, and cannot fully display the angle and trajectory of the skeleton mov...
