Needle adsorption structure of cleavage bulb biopsy needle

The utility model relates to a needle head adsorption structure of a cleavage bulb biopsy needle, and belongs to the technical field of auxiliary reproductive medicine in-vitro fertilization micromanipulation instruments. Comprising a needle body of a hollow structure, the front end of the needle body is an inclined plane, an arc transition part is arranged between a high point and a low point of the inclined plane, and the inclined plane end of the low point is flush and parallel to the radial perpendicular line of the needle body. The needle head adsorption structure of the cleavage bulb biopsy needle has the advantages of being simple in structure and good in practicability, in the cleavage bulb biopsy operation process, the cleavage bulb can be positioned through the arc transition part on the end head inclined face port, and the contact area between the needle head body and the cleavage bulb is increased; the problem that an existing polar body biopsy needle cannot be adsorbed frequently due to the struc
