FIXING DEVICE FOR FIXING RAT TESTIS FOR INJECTION

摘要

The present invention includes a positioning tube, one end of the positioning tube is installed to form a cone, the other end is provided with a cradle, and a restraint device for restraining the body of a rat is installed in the positioning tube, and the A sliding groove is opened in the cradle along the longitudinal direction of the positioning tube, a contact sheet is installed in the sliding groove, a contact cam is rotatably installed in the contact sheet, and a hole sheet at one end separated from the positioning tube of the holder is installed, and a U-shaped elastic restraint arm is swingably installed in the hole sheet, two free ends of the elastic restraint arm are bent to form a pin, and the pin is installed to be inserted into the hole sheet, and the elastic restraint arm is installed to be inserted into the hole sheet. A first positioning groove, a first restraining protrusion, a second positioning groove, a second restraining protrusion, and a third positioning groove were sequentially formed on the mixing surface of the outer wall of the hole sheet to which the constraint arm is attached, and the second positioning groove is A fixation device used for fixing and injecting the testicles of mice installed deeper than the first positioning groove and the third positioning groove was disclosed. Its overall structure is simple, and it is easy for cell transplantation experiments because it can fix mouse testicles.
