Description

technical field [0001] The invention relates to a microelectronic medical experimental manipulation treatment instrument, which is a spinal manipulation simulation instrument that can be used in animal experiments, and can accurately and quantitatively simulate traction, rotation, side bending and other manipulations for testing the mechanical properties of animal vertebral joints. Background technique [0002] Spinal manipulation therapy is a conservative treatment method developed in the 20th century and rapidly popularized mainly for strain degenerative spinal soft tissue injury diseases. The main conservative treatment widely used in the treatment of degenerative spinal diseases is popular in both the East and the West due to its often immediate and miraculous effects. Spinal manipulation: Generally speaking, the manipulation is roughly divided into two parts. One part is compared with Western soft tissue release techniques, and the other part is joint adjustment. The ...

Problems solved by technology

However, the traction table does not have the function of simulating maneuvers

[0005] Prior art CN2645634Y discloses a lumbar traction massage bed in standing and lying position. The bed is installed on a rotating frame, which can rotate around the axis. For traction therapy, the angle of traction massage only changes within 90 degrees, and manual massage is required, which cannot achieve the simulation effect of spinal manipulation in animal experiments

[0006] The three-dimensional spinal traction bed disclosed in Chinese patent 95112202.9 can only perform linear traction, angulation and rotation in the form of treatment, and none of these three treatment methods can be effectively combined in twos or twos during the treatment process. That is, only one of the three movements of traction, angulation or rotation is performed in the same direction at the same time, and it is impossible to achieve true three-dimensional integrated treatment

It is also impossible to achieve the simulation effect of spinal manipulation in animal experiments

[0007] At present, the lumbar traction bed commonly used in clinic also has a single function, which can only complete axial stretching and traction, without functions such as local massage and rotation, and cannot achieve the simulation effect of spinal manipulation required in animal experiments.
