Description

Technical Field

[0001] This utility model relates to the field of tissue sampling technology, and more specifically, to a fur-spreading device for subcutaneous tissue sampling in animals. Background Technology

[0002] Animal subcutaneous tissue sampling is mainly used in animal experiments. The obtained subcutaneous tissue samples are often used for sterile cell culture. Spreading the fur is to safely and effectively expose the skin and subcutaneous tissue, and to prevent the cut fur from adhering to the subcutaneous tissue and causing contamination.

[0003] Traditional animal subcutaneous tissue sampling methods are not convenient because it is difficult to stretch the animal's fur, resulting in insufficient exposure of the subcutaneous tissue, which affects the operation of personnel. Moreover, the cut fur is also easy to adhere to the tissue, causing tissue contamination.

[0004] Therefore, a fur-spreading device for subcutaneous tissue sampling in animals was proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fur-spreading device for subcutaneous tissue sampling in animals, so as to solve the problems of inconvenience in freeing up hands, affecting personnel sampling, and the shadows that often appear in subcutaneous tissue due to obstruction or light, affecting the surgical field.

[0006] To achieve the above objectives, a fur spreading device for subcutaneous tissue sampling of animals is provided, comprising a first spreading rod, a second spreading rod rotatably disposed at the center of the surface of the first spreading rod; threaded holes are provided on the surfaces of both the first and second spreading rods, and a positioning mechanism is provided internally in the threaded holes; a connecting rod is fixedly disposed at the end of the first and second spreading rods away from the positioning mechanism; a fixing frame is fixedly disposed at one end of the connecting rod, and a spreading mechanism is fixedly disposed on one side of the fixing frame.

[0007] As a further improvement to this technical solution, the positioning mechanism includes a stud rod and a locking knob. The stud rod is threaded inside the threaded hole, and the locking knob is threaded on the surface of the stud rod near the second spreading rod. The locking knob is used to fix the stud rod.

[0008] As a further improvement to this technical solution, a movable groove is provided on the top surface of the second support rod, and the movable groove is adapted to the stud rod.

[0009] As a further improvement to this technical solution, the number of fixing frames is two sets, and the two sets of fixing frames are symmetrically arranged. The fixing frames are used to fix the positioning mechanism.

[0010] As a further improvement to this technical solution, the spreading mechanism includes a spreading plate and an inner buckle plate. The spreading plate is fixedly disposed on one side of the fixing frame, and the inner buckle plate is fixedly disposed on the top surface of the spreading plate.

[0011] As a further improvement to this technical solution, a rotating plate is fixedly provided at the end of the stud rod away from the locking knob. The surface of the rotating plate is provided with an anti-slip sleeve, and the rotating plate is used to drive the stud rod to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this animal subcutaneous tissue sampling fur spreading device, the first spreading rod and the second spreading rod are separated to spread the animal fur apart. At this time, the two spreading mechanisms are placed inside the animal fur, and the fixing frame is placed outside the animal fur. The inner buckle plate cooperates with the fixing frame to spread the animal fur apart, which achieves the effect of spreading the animal fur apart, making it easier for personnel to sample the subcutaneous tissue, and also reducing the adhesion of animal hair to the subcutaneous tissue, which would affect the sampling.
