Vacuum aspiration curet

Abstract

The invention discloses a vacuum aspiration curet which comprises a scraping head and a handle, wherein the scraping head is a hollow tube, one end of the hollow tube is a of a spoon structure, the spoon part of the scraping head is provided with a vacuum aspiration hole, the other end of the hollow tube is an external thread structure, the handle is hollow, one end of the hollow handle is of an internal thread structure, the other end of the hollow handle is provided with a negative pressure connector, a through negative pressure adjusting hole is formed in the hollow handle, and the scraping head and the handle are connected through the external thread structure and the internal thread structure. According to the vacuum aspiration curet, the curet is combined with negative pressure, fell-off tissue can be sucked out during tissue scraping, pollution of the fell-off tissue to other tissue within an operation area is avoided, operation processes are simplified, tissue scraping can be achieved in a one-shot mode, the complicated operation in which scraping and taking are conducted independently is avoided, using is convenient, and the promotion value is high.
