Problems solved by technology

However, the intervertebral disc degeneration induced by this method usually includes simultaneous or sequential degeneration of the nucleus pulposus, annulus fibrosus, and cartilage endplate, and is likely to cause damage to the internal structure of the intervertebral disc. For the study of degeneration of a certain intervertebral disc structure, this Insufficient

Embodiment Construction

[0016] Take an experimental mouse, anesthetize it, select the pre-pressurized tail vertebrae segment, place the matching rat tail vertebral puncture modeling device on the mouse tail, insert the puncture needle into the matching rat tail vertebral puncture modeling device, Then the operator holds the needle seat 4 with one hand, so that the needle point 1 slowly penetrates the epidermis of the rat tail and reaches the surface of the rat tail vertebrae. At this time, the smooth needle body 2 is located in the casing of the matching instrument, and the threaded needle body 3 is located outside the casing of the matching instrument. The depth-limiting sleeve is located on the threaded needle body 3 through the threaded connection between the internal thread structure 10 and the half-thread structure 6. The puncture entry point is confirmed by the C-arm machine, and the target point to be punctured is selected on the X-ray of the mouse tail, and two points are calculated. According...

Abstract

The invention relates to a mouse caudal vertebra puncture needle suitable for a mouse caudal vertebra puncture model device. The mouse caudal vertebra puncture needle is composed of a needle body, a needle base and a depth limiting sleeve. The needle body is composed of a smooth face needle main body and a threaded needle main body. A needle tip is arranged at one end of the smooth face needle main body, and the other end of the smooth face needle is connected with the threaded needle main body. The other end of the threaded needle main body is connected with the needle base. The needle body and the needle base are of an integrated structure. The depth limiting sleeve and the threaded needle main body are connected in a threaded mode. The length of the puncture needle is limited by rotating the depth limiting sleeve. The depth limiting sleeve is fixed to the needle body through a fastening screw on the limiting depth sleeve. Depth limitation on the puncture needle is achieved through the mouse caudal vertebra puncture needle, and the mouse caudal vertebra puncture needle is easy and accurate to operate and can be better applied to animal research in the field.

Description

technical field [0001] The invention relates to a rat tail vertebra puncture needle adapted to a rat tail vertebra puncture modeling device. Background technique [0002] Intervertebral disc degeneration is the main cause of spinal degenerative diseases such as cervical spondylosis and lumbar disc herniation. It can cause neck, shoulder, waist and leg pain and other symptoms. In severe cases, surgical treatment is required. The intervertebral disc consists of three parts: the nucleus pulposus, the annulus fibrosus, and the cartilage endplate. The cartilage endplate constitutes the upper and lower boundaries of the intervertebral disc, and is the main way for the nucleus pulposus to exchange nutrients and metabolites with the outside world. In addition, the cartilage endplate plays an important role in maintaining the normal shape of the vertebral body and buffering and protecting the intervertebral disc stress. The degeneration of the cartilage endplate not only directly a...
