Rat caudal vertebra intercalated disc minimally invasive puncture injection device

Abstract

The invention relates to a rat caudal vertebra intercalated disc minimally invasive puncture injection device which is used for conducting minimally invasive puncture or injecting liquid on a fibrous ring in a rat tail. The rat caudal vertebra intercalated disc minimally invasive puncture injection device comprises a lantern ring, a needle handle and a needle plug. The lantern ring is of a hollow cylinder structure, the middle of the lantern ring is a sleeving hole used for sleeving the rat tail, a needle handle insertion hole and a locating hole are formed in a lantern ring body, and the needle handle insertion hole and the locating hole are arranged in a spaced mode and both communicated with the sleeving hole; the needle handle comprises a clamping portion of the upper end, a middle insertion portion and a needle, the insertion portion can be inserted and connected in the needle handle insertion hole, and a needle plug hole is formed in the clamping portion; the needle plug can be inserted into the needle plug hole to block the needle handle. Compared with the prior art, according to the rat caudal vertebra intercalated disc minimally invasive puncture injection device, the lantern ring is fixed on the rat tail, and the needle handle is inserted into the lantern ring, so that the minimally invasive puncture to the rat tail is achieved; the structure is simple, and the operation is convenient; meanwhile, the stability to the rat tail is stronger, the lantern ring can rotate on the rat tail, and therefore a circle of minimally invasive puncture on the fibrous ring can be conducted.

Description

technical field [0001] The invention relates to a puncture device, in particular to a rat tail intervertebral disc minimally invasive puncture injection device, which belongs to the field of medical instruments. Background technique [0002] Animal laboratories are the primary avenue for research into various treatments that block or reverse intervertebral disc degeneration. At present, rats are used as experimental animals in the study of intervertebral disc degeneration in spinal surgery. The position of the rat tail intervertebral disc is an anatomical position that is easy to operate, and can be easily manipulated to induce degeneration, so it becomes an ideal model for the study of intervertebral disc degeneration / regeneration. However, in the prior art, the model is caused by mechanical disturbance to induce intervertebral disc degeneration, which also requires complex operations, sophisticated external fixation instruments and mechanical detection instruments, and it...

Problems solved by technology

The puncture device has a precise and complex structure and high manufacturing cost. At the same time, the puncture device is mainly suitable for use in thoracic and laparoscopic surgery. Because it lacks a fixing and positioning structure for the rat tail, the puncture device is not suitable for large Rat tail intervertebral disc minimally invasive puncture
