Quantitative tissue mass incision and implantation device

Abstract

The invention relates to a quantitative tissue mass incision and implantation device, comprising a rectangular outer thimble, a rectangular inner thimble, a rectangular locating core and a swivel knife; the rectangular locating core with sealed front face is movably and internally sleeved in the inner thimble, and the rectangular locating core and the inner thimble are movably and internally sleeved in the outer thimble together; the swivel knife is arranged in the thimble wall at the front end of the rectangular inner thimble; the swivel knife comprises a swivel knife head and a swivel knifehandle; the swivel knife head is fixedly connected on the swivel knife handle; the swivel knife handle is arranged in the side wall of the rectangular inner thimble in the axial direction and extendsbackward out of the side wall; the swivel knife head is arranged in the side wall of the rectangular inner thimble in the direction of end face; when the swivel knife rotates, the swivel knife head transversely incises a lumen end face of the rectangular inner thimble. By adopting the above technical proposal, a set of standard tumor mass incision and implantation devices is designed and manufactured, and in combination with the stipulated use method, serious defects in the process of manufacturing current models can be effectively evaded and standardization degrees of animal tumor formation models can be improved.

Description

technical field [0001] The invention is applicable to the field of experimental surgery, and relates to a tissue block cutting and planting device in the operation of using primary tumor tissue blocks for direct planting and tumor formation, and in particular to a quantitative tissue block cutting and planting animal tumor formation model and planting devices. Background technique [0002] Malignant tumors have become a major disease that threatens human health. With the advancement of surgical technology, most solid tumors can be surgically resected to obtain relatively good short-term curative effect, but the high recurrence and metastasis after surgery are still restricting clinical practice. Therefore, it has become a hot issue in the field of tumor research. [0003] At present, cell models and animal models are mostly used for basic and applied basic research on tumor recurrence and metastasis, and animal tumor models are mostly used for surgery-related research. At ...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a quantitative tissue block cutting and planting device in the cutting and planting animal tumor formation model, which solves the problem that the size and shape of the cut tissue block are difficult to accurately control, and there are large differences between different individuals. Differences, the defects that the judgment standards cannot be unified, and the direct contact of the forceps with the tumor mass increases the chance of tumor cell dissemination in the sinus tract when the forceps enter and exit the sinus tract
