Abstract

The invention provides a limb bone movement simulation structure. A movable structure is connected between caput femur and pelvis or between scapula and humerus. The limb bone movement simulation structure is characterized in that the movable structure comprises an L-shaped plate, two perpendicular face plates of the L-shaped plate are respectively provided with shaft holes and shaft pins matched with the shaft holes. The shaft holes on one face of the L-shaped plate of a metal construction member are connected with the caput femur or the humerus through the shaft pins, and the shaft holes on the other face are connected with the pelvis or the scapula through the shaft pins to form the movable structure between the caput femur and the pelvis or between the scapula and the humerus and to form the simulation structure capable of simulating limb bone movements. The outer face portion of a bearing of the pelvis or the outer face portion of a bearing of the scapula is an arc face. A side portion of the other perpendicular face plate of the L-shaped plate is provided with a limiting boss which is movably matched with the arc face to control rotation angle between the femur and the pelvis or between the scapula and the humerus, and to simulate limitation of limb movements of a human body. The limb bone movement simulation structure is exquisite in structure, vivid in appearance, economic, applicable, and capable of well achieving the purposes of teaching and training.

Description

Limbs bone motion simulation structure

Technical field

The present invention relates to Medical teaching equipment, is a kind of limbs bone motion simulation structure specifically.

Background technology

Existing various simulation is human-like, owing to not solving skeleton motion simulation architecture problem, usually causes function limitation, vivid distortion, particularly when the teaching operation of medical science and training, can not make training more true to nature, does not also reach very good effect and the aim of learning.

Summary of the invention

For addressing the above problem, the invention provides a kind of limbs bone motion simulation structure.Limbs bone motion simulation structure of the present invention, femoral head with pelvis between or be connected by a bascule between shoulder blade and humerus, it is characterized in that: bascule contains a L-type plate, and two vertical panels of L-type plate all respectively carry axis hole, also has the pivot pin with shaft hole matching; One of L-type plate vertical panel inboard arranges femoral head or upper end of humerus, there is the free gap another vertical panel of femoral head or upper end of humerus and L-type plate inboard, pivot pin passes the axis hole of this vertical panel and the axis hole of femoral head or upper end of humerus, and pivot pin two ends are with plush copper or nut; The arranged outside of said another vertical panel of L-type plate pelvis or shoulder blade, another pivot pin passes the axis hole of this vertical panel and the bearing of pelvis or shoulder blade, the pivot pin two ends are with plush copper or nut, the bearing exterior portion of pelvis or shoulder blade is arc surface, another vertical plane edges of boards of said L-type plate section is with positive stop lug boss, and positive stop lug boss and arc surface are movingly.

Like this, the L-type plate and two vertical axis holes are arranged and limit section with a positive stop lug boss, the pivot pin that also have to coordinate; Axis hole of the L-type plate of hardware is connected with femur or humerus by pivot pin, the another side axis hole is connected with pelvis or shoulder blade by pivot pin, formed between femoral head and pelvis or the bascule between shoulder blade and humerus, consisted of and to have imitated limbs bone motion simulation structure.One each vertical plane be rotationally connected by pivot pin, but transverse rotation (limbs abduction and interior receipts), but be subject to the restriction of femoral head and upper end of humerus and another vertical plane gap, can only the certain angle of transverse rotation, also just imitated the limit of people's limb activity abduction.Another vertical plane and pelvis and shoulder blade are rotationally connected by pivot pin, can vertically rotate (or deserving to be called lower rotation or limbs lifting); Another side is connected with humerus with femur, but transverse rotation (limbs abduction and interior receipts).But be subject to equally the restriction of scope movingly of positive stop lug boss and arc surface, can only vertically rotate a certain angle, also lift the movable limit of leg or front and back, carry arm up and down with regard to the limb activity that has imitated the people.

Limbs bone motion simulation structure can be the structural model of femur and pelvis or shoulder blade and humerus, so that the student understands structure and kinematic relation between femur and pelvis or shoulder blade and humerus; Perhaps limbs bone motion simulation structure is put into manikin, can be by the operation of manikin being understood structural relation and the kinematic relation between femur and pelvis or shoulder blade and humerus; Perhaps be provided with emulation skin and flesh outside limbs bone motion simulation structure, carry out body local operation and training.Delicate structure of the present invention, lifelike image, economic and practical, can reach good teaching and training goal.

Specific embodiment

Embodiment 1

A kind of limbs bone motion simulation structure has emulation femur 1 and pelvis 2, is connected 3 by a bascule between femoral head and pelvis.Bascule contains a L-type plate, and two vertical panels of L-type plate all respectively carry axis hole 4, also has the pivot pin 6 with shaft hole matching; One of L-type plate vertical panel inboard arranges femoral head, there is the free gap another vertical panel of femoral head and L-type plate inboard, pivot pin passes axis hole and the capital axis hole of this vertical panel, and in pivot pin two ends, an end is with plush copper, and the screw thread of the other end is connected with nut; The arranged outside of said another vertical panel of L-type plate pelvis, and another pivot pin passes the axis hole of this vertical panel and the bearing of pelvis, and in pivot pin two ends, an end is with plush copper, and the screw thread of the other end is connected with nut.The bearing exterior portion of pelvis is arc surface, and another vertical plane edges of boards of said L-type plate sections is with positive stop lug boss 5, and positive stop lug boss and arc surface are movingly.The L-type plate is hardware, and it is boss 5 of metal bending with positive stop lug boss 5 that the L-type plate has two vertical axis holes 4 and limit section, the also metal pivot pin 6 that coordinates in addition axis hole that femur is connected with pelvis.

Femur is connected by movable connection structure of the present invention with pelvis, has well imitated the dirigibility in shoulders of human body joint.L-type limit section with spacing hardware 5, make femur be subject to certain resistance when rotating, imitate resistance and toughness that in human synovial, the structural relation between muscle, muscle and bone produces.Femur is connected by the L-type plate with pelvis, and L-type plate one end is connected with shaft hole matching by the metal pivot pin with femur, and the other end is connected with pelvis with shaft hole matching by the metal pivot pin.The femur and the pelvis that connect are put into manikin, by the operation of manikin being understood structural relation and the kinematic relation between femur and pelvis, can reach fine teaching, training goal.
