Description

Technical Field

[0001] The utility model relates to the technical field of scanning auxiliary devices, in particular to a nuclear magnetic resonance scanner. Background Art

[0002] Since primates and humans have 75-98.5% homology in DNA, their physiological structure, system organization and other biological characteristics are very similar to those of humans. Therefore, primates are often used as substitutes for humans in scientific research, such as crab-eating macaques. In scientific research, nuclear magnetic resonance imaging is usually used to study the mutations and early lesions of animal organs, such as arthritis of the knee joint. Nuclear magnetic resonance imaging is a means of structural analysis of physical phenomena. It scans animals with a scanner and presents them in the form of images for analogy with humans. The nuclear magnetic resonance imaging of crab-eating macaques takes 60-80 minutes. The crab-eating macaque needs to remain motionless during the examination, otherwise the accuracy of the examination will be affected. In the existing scanning of crab-eating macaques with arthritis, in order to prevent the crab-eating macaques from moving around during the examination, sandbags are usually tied to the monkeys' legs after the crab-eating macaques are anesthetized to fix the lower limbs of the crab-eating macaques. However, this fixation method has certain defects. On the one hand, tying up the monkey will increase the monkey's discomfort and make it more likely to cause unconscious movements. On the other hand, the sandbag fixation cannot deflect the angle of the monkey's knee joint well. For this reason, we propose a nuclear magnetic resonance scanner. Utility Model Content

[0003] A technical problem to be solved by the present application is: how to design a fixing structure for monkeys so that the monkeys can be fixed and the angle of the knee joint can be easily adjusted.

[0004] In order to solve the above technical problems, the present application provides a nuclear magnetic resonance scanner, including a scanner body, and also including:

[0005] A C-shaped tube, wherein the C-shaped tube is rotatably disposed on the scanner body, and a plurality of C-shaped tubes are provided for placing the legs of the cynomolgus macaque;

[0006] A restraint belt, wherein the restraint belt is fixedly arranged on the C-shaped tube;

[0007] A deflection assembly is arranged on the scanner body. The thigh and calf of the crab-eating macaque are placed in two C-tubes respectively, and the C-tube is deflected. The deflection assembly is used to drive the other C-tube to deflect and fix it, and the C-tube and the macaque's leg are positioned using a restraint belt.

[0008] In some embodiments, the deflection assembly includes an axis one fixedly mounted on a C-shaped tube, a deflection rod is rotatably mounted on the axis one, a groove one is provided on the deflection rod, an axis two is fixedly mounted on another C-shaped tube, the axis two is located in the groove one, a locking assembly is provided on the axis two, and the deflection rod is positioned by using the locking assembly.

[0009] In some embodiments, the locking assembly includes a second groove opened on the deflection rod, and there are multiple grooves opened. A sleeve is sleeved on the second shaft, and the sleeve is located in the second groove. A third groove is also opened on the deflection rod. A fixed plate is slidably connected to the first shaft, and the fixed plate is located in the third groove.

[0010] In some embodiments, a tension spring is disposed in the sleeve, and two ends of the tension spring are respectively fixedly connected to the sleeve and the second shaft to drive the sleeve to slide into the second groove.

[0011] In some embodiments, the multiple C-tubes are arranged in groups of two to fix the thighs and calves of the macaque, and the multiple groups of C-tubes are symmetrically designed to fix the two legs of the macaque, respectively. The deflection rods are also provided in plurality.

The angle of the macaque's knee joint can be adjusted and fixed conveniently and quickly, so that the anesthetized macaque during the MRI scan will not affect the scanning effect due to unconscious body movements. It is convenient, fast, simple and practical, and improves the work efficiency of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

The C-shaped tube 2 is slid, and the deflection rod 42 is slid at the same time to adjust the C-shaped tube 2 to a suitable position, so that the monkey's thigh and calf can be placed in the two C-shaped tubes 2 respectively. Since the C-shaped tube 2 is inclined compared to the ground, the monkey's legs can be placed on the C-shaped tube 2 without worrying about falling. After the relative position of the C-shaped tube 2 and the deflection rod 42 is adjusted, the sleeve 52 is rotated and slid until the sleeve 52 slides into the second groove 51 to align the deflection rod 42. The length of the deflection rod 42 is fixed at one end, and the other end is used to slide the fixing plate 54 to the slot three 53 to fix the angle of the deflection rod 42.
