Problems solved by technology

However, its injury acts on both sides of the spinal cord, which is different from the front and rear compression injury factors of humans, and because the difference in the elastic modulus of different arterial clip metals is different from the development of the spinal cord of the animal itself, it is difficult to achieve individual injury factors. customization and precise control

Abstract

The invention belongs to the field of experiment instruments and relates to an animal spinal cord injury modeling device. The animal spinal cord injury modeling device is composed of a conveying and control device, a supporting structure and mechanical arm and a measurement and control striking device. The measurement and control striking device comprises a pair of metal pincers, a laser transmitter, a laser receiver, a pressure sensor and a speed-adjustable bidirectional engine. The supporting structure and mechanical arm consists of a base, a fixing sleeve, a mechanical arm and four nuts 9. The conveying and control device comprises a computer terminal and a data line. The blank of a pincers clipped type animal spinal cord injury automatic modeling instrument is filled, a spinal cord back side and ventral side oppressive modeling mode of the animal spinal cord injury modeling device meets human spinal cord injury factors, oppression strength and oppression time can accurately controlled, and the accuracy and uniformity of a spinal cord injury model can be improved.

Description

technical field [0001] The invention belongs to the field of experimental instruments, in particular to an animal spinal cord injury modeling device. Background technique [0002] Spinal cord injury is one of the modern frequently-occurring diseases, which often leads to the permanent loss of the patient's working ability and causes a great burden on the patient's family and society. The current treatment methods for spinal cord injury are limited, and the treatment effect is not ideal. The animal model of spinal cord injury is a necessary condition for research related to spinal cord injury. At present, the commonly used models are heavy blow model, complete spinal cord transection model, spinal cord half transection model, and spinal cord clamp injury model. The heavy object impact model was first invented by Allen et al. in 1911. A fixed weight falls freely at a fixed height, causing impact damage to the spinal cord. It is the earliest spinal cord injury model establish...
