Fixtures for Immobilizing Rat Testicles for Injection

Abstract

The invention discloses a fixing device for fixing testicles of rats for injection, which includes a positioning tube, one end of the positioning tube is tapered, and a bearing platform is set at the other end, a binding piece is set in the positioning tube, and A sliding groove is provided on the carrying platform, and a collision seat is arranged in the sliding groove, and a collision cam is rotated on the collision seat, and a hole seat is provided on the carrying platform, and a hole seat is oscillatingly arranged on the hole seat. U-shaped elastic restraint arm, the two free ends of the elastic restraint arm are bent to form pins, the pins are inserted into the hole seat, and the elastic restraint arm is closely attached to the mating surface of the outer wall of the hole seat A first positioning groove, a first converging protrusion, a second positioning groove, a second converging protrusion and a third positioning groove are formed, and the second positioning groove is deeper than the first positioning groove and the third positioning groove. The overall structure is simple, and the testis of rats can be fixed, thereby facilitating cell transplantation experiments.

Description

Technical field [0001] The present invention relates to the technical field of medical experimental instruments, in particular a fixing device for immobilizing rat testis. Background technique [0002] In the cell transplantation experiment, rat testicles were often required, and then the cells to be transplanted were injected into the testicles of rats by micro-injection needles. However, during the operation, since the testicular volume of the rats is small, the injection is inconvenient, and is very sensitive. When it is stimulated, it is easy to contract into the groadoy, which affects the injection operation, and therefore, two operators are currently required for testicular injection operation. A operator needs to be bound by the rat, and then fix the testicular testicles by hand, and another operator is injected, but the two operators are inconvenient, due to injection, rat testis is bonded The hind legs of rats will also struggle, affecting the operation of the operator, ...

AI Technical Summary

Problems solved by technology

However, during the operation, due to the small size of the testicles of rats, it is inconvenient to position the injection and is very sensitive. When stimulated, it is easy to shrink into the groin and affect the injection operation. Therefore, two operators are currently required to perform the testicular injection operation. One operator needs to restrain the rat, and then fix the testis of the rat by hand, and the other operator performs the injection operation, but it is inconvenient for the two operators to cooperate in this operation. Due to the injection, when the testis of the rat is restrained , the rat's hind legs will also struggle, which will affect the restraint action of the operator and reduce the test efficiency
