Spine simulation structural body for teaching

Abstract

Disclosed is a spine simulation structural body for teaching. The spine simulation structural body for teaching comprises a vertebra and connecting structures among bone joints and is characterized in that each connecting structure between adjacent bone joints of the vertebra is a cardan joint, and the bone joints are connected through the cardan joints. Opposite surfaces of adjacent bone joints of the vertebra are provided with connecting grooves and connecting rods which are in hinge joint with the connecting grooves, articulated shafts at two ends of each connecting rod are perpendicular to each other and staggered with each other, and end faces at two ends of each connecting rod are arc surfaces and each arc surface takes the articulated shaft at the same end as an axes. A corresponding arc surface is arranged at the bottom of each groove. By means of the connecting structure of the cardan joints, adjacent bone joints are connected, and a complex connecting structure with nerves, ribs and muscles between back bones of the vertebra of a human body is replaced. Multi-dimensional change process and states between the bone joints can be achieved, and a plurality of states of stretch and bend simulating the vertebra of the human body can be achieved, so that people can be trained through a real treating and nursing process of the vertebra. By means of the spine simulation structural body for teaching, angles needed by various vertebra training can be met, and the distance between the training and the practical application is shortened.

Description

technical field [0001] The invention relates to a medical teaching tool, in particular to a spine simulation structure for teaching, which uses the free rotation and rotation angle of the bionic human spine to improve the teaching quality of the spine and the learning effect of the spine for students. Background technique [0002] Nowadays, in various medical teaching processes at home and abroad, the external form, internal structure and function of the model should be very similar to the form, structure and function of the real human body when teachers are teaching and students are operating, so as to be better To achieve the purpose of teaching and receive the best training effect. The spine in the current bionic human body model basically cannot achieve the effect of realistic external shape, the same internal structure, and the same function as the real human spine. In the process of teaching and practice, the authenticity and operability will be greatly affected. Ther...
