Technical Field
The invention relates to the technical field of medical equipment, in particular to a device convenient for anesthesia, fixation and shooting of experimental rats.
Background
Rats are commonly used laboratory animals. In the rat experiment, the rats are first grabbed and fixed beforeCan be used forThe rats are injected with anesthetic drugs intraperitoneally, and the operation is performed after the anesthesia takes effect. However, the purpose isThe space size of the rat catching cylinder which is commonly used before can not be adjusted and reduced at will, and the rat has larger activity space in the rat catching cylinder, so that the rat can not be fixed reliably and is not moved, and inconvenience is brought to intraperitoneal injection of gunpowder, which is one of defects. Secondly, the femur of the rat is the most commonly used model of fracture and bone defect, and the bone growth condition is known by taking X-ray pictures or checking with Micro-CT periodically after the fracture and bone defect are repaired. Standard limb radiographs include orthotopic and lateral radiographs to facilitate understanding of bone growth around the bone. The lower limb (femur) of the rat is easier to achieve when taking the X-ray correction film, however, the X-ray side film is difficult to take because the standard X-ray side film requires a special body position in which the limb is rotated by 90 degrees or the body is fixed in an upright position, and the upper limb and the lower limb cannot be overlapped. If the upper limb and the lower limb overlap when taking the X-ray side position slice, the bone growth condition of the lower limb (femur) is affected, unless the experimental rat is controlled manually and the trunk and the upper limb are buckled, the upper limb and the lower limb can be prevented from overlapping when taking the X-ray side position slice, but an operator needs to suffer from X-ray radiation.
The patent publication No. CN210903076U, a veterinary animal film shooting fixing bracket, has the advantages that only a single limb position shooting performance of an animal is fixed by the fixing bracket, the lower limb of the animal is not rotated by 90 degrees or placed in a body upright position, and the overlapping of the lower limb and the upper limb is not avoided.

As can be appreciated by those skilled in the art, the size of the distance between the two transverse holes determines the bending angle of the first fixing plate 12a and the second fixing plate, and when the distance between the two transverse holes is half the thickness of the fixing plate, the bending of the joint of the first fixing plate 12a and the second fixing plate 12b is approximately 90 degrees at maximum. When the X-ray film on the positive side of the lower limb of the rat is required to be shot, one of the first shaft 11a and the second shaft 11b is pulled out, the joint of the first fixing plate 12a and the second fixing plate 12b is bent and buckled by approximately 90 degrees, the pulled out first shaft 11a or second shaft 11b is inserted again, the bent fixing plate can be prevented from being straightened, the bending and buckling state of the fixing plate is maintained, the trunk of the rat is driven to buckle, and the upper limb and the lower limb of the rat cannot be overlapped when shooting the film on the positive side of the X-ray.
