Abstract

The invention discloses a puncture core assembly. The puncture core assembly comprises a puncture assembly, a sewing assembly and a regulating unit, wherein the puncture assembly comprises a punctureend and a puncture rod; the sewing assembly is positioned in the puncture rod; at least one part of the sewing assembly can move in the puncture rod; an accommodating space is formed between the puncture end and the puncture rod; the regulating unit controls the height of the accommodating space; the sewing assembly moves, so that one end of a sewing line passes through a tissue in the accommodating space. According to the puncture core assembly and the puncture unit provided with the same disclosed by the invention, a puncture hole does not need to be expanded, so that the puncture effect canbe realized to establish a channel, and sewing of the puncture hole can be realized in the narrow and small puncture hole; sewing height can be regulated according to individual difference of the target tissue; and puncture hiatus hernia caused by a minimally invasive surgery puncture hole is effectively avoided, and postoperative rehabilitation of a patient is facilitated.
