Problems solved by technology

For the breast, it is also a fine-needle aspiration biopsy, which is also a vacuum-assisted biopsy, and it is not yet possible to do a complete central biopsy of the diseased tissue
Only marginal tissues can be cut, which is easy to cause misdiagnosis and mistreatment
[0003] In addition, the biopsy of the thyroid gland is prone to bleeding, nerve and blood vessel damage and complications of asphyxia, so there is almost no needle biopsy for it.
Although the existing vacuum-assisted biopsy system can remove the tumor, it can only cut the biopsy from the edge of the tumor, even if it penetrates into the tumor, it can only cut the specimen in one direction.
In addition, because the size of the knife notch is constant, a large amount of normal tissue is removed at the same time as the small tumor is removed, especially for small tumors.
Also, hemostasis is not good after biopsy, so it is not suitable for thyroid biopsy

Abstract

The invention discloses an adjustable scalpel head for minimally invasive soft tissue central biopsy. The scalpel head comprises a shell, one end of the shell is provided with a scalpel tip for puncture, a negative pressure cutting device for cutting human body tissues is arranged in the shell, and a driving device for driving the negative pressure cutting device to cut the tissues is arranged in the shell. The prism-shaped front end of the scalpel tip transits backwards into a cone shape.

Description

technical field [0001] The invention relates to a medical device, in particular to an adjustable minimally invasive soft tissue center biopsy cutter head. Background technique [0002] For the biopsy of diseased tissue, only the complete central part has the highest diagnostic value. At present, there is only a minimally invasive biopsy system for the breast, and there is no special biopsy system for the thyroid. For the breast, it is also a fine-needle aspiration biopsy, and it is also a vacuum-assisted biopsy. It is not yet possible to do a complete central biopsy of the lesion. Only the marginal tissue can be cut, which is easy to cause misdiagnosis and mistreatment. [0003] In addition, because the thyroid gland is prone to bleeding, there are complications of nerve and blood vessel injury and asphyxia, there are almost no needle biopsies for it. Although the existing vacuum-assisted biopsy system can remove the tumor, it can only cut the biopsy from the edge of the ...
