Abstract

The invention provides a device for extracting and delivering germ cells in the in-vivo experimental rat genital tract and belongs to the technical field of animal embryology. The device for extracting and delivering the germ cells in the in-vivo experimental rat genital tract consists of a moving suction ball (1), a suction and delivery tube (2), an operating bag (3), a computer data line (39) and a control computer (40) and is characterized in that the moving suction ball (1) is olive-shaped, the cross section of the moving suction ball (1) is oval, the longest diameter of the moving suction ball (1) ranges from 0.5 cm to 1 cm, and the shortest diameter of the moving suction ball (1) ranges from 0.05 cm to 0.3 cm. A ball top suction opening (4), a camera (28) and a flash lamp (29) are arranged at the front end. Two to five circles of forwards-moving tube feet (6) are arranged at the front half portion, four to eight ball waist suction openings (5) are arranged in the middle, two to five circles of receding tube feet (7) are arranged at the rear half portion, a ball tube connector (8) is arranged at the rear end and enables the moving suction ball (1) and the suction and delivery tube (2) to be connected together. The device for extracting and delivering the germ cells in the in-vivo experimental rat genital tract is simple in manufacture, good in operability, low in cost and obvious in effect.

Description

technical field [0001] The invention relates to a device for sending and taking germ cells in the reproductive tract of rats in live experiments, and belongs to the technical field of animal embryology. Background technique [0002] At present, in the process of artificially extracting eggs from inside the living animal, the common method is to extract eggs by means of ultrasonic puncture. This method first needs to take medicine to expel the eggs, and then perform surgical puncture. Ultrasound is irritating to the human body to a certain extent. Taking medicine and surgery will cause great harm to the animal body. A large number of ovulation-stimulating drugs have obvious side effects. After taking the medicine, adverse reactions such as renal failure and other ovarian hyperstimulation syndrome often occur. At the same time, there are certain risks during the operation, such as infection, which does not conform to the 3R principle advocated by people in animal welfare resea...
