Description

a tissue stripper

technical field

The utility model relates to the technical field of biological extraction, in particular to a tissue stripper.

Background technique

Tissue dissection, that is, dissection of soft tissues that are close to each other, adhered or entangled. For example, the dental follicle tissue on the teeth is peeled off, and the soft tissue adhered to the bone is peeled off. Among them, when the dental follicle tissue on the tooth is peeled off, the stem cells can be separated from the dental follicle tissue. Stem cells are cells with multi-directional differentiation potential, which can be induced to differentiate into osteoblasts, chondrocytes, adipocytes, etc. When peeling the dental follicle soft tissue from hard tissue such as teeth, the dental follicle soft tissue needs to be peeled off from the hard tissue first, and then used for cell culture.
