Abstract

The invention discloses a puncture core assembly. The puncture core assembly comprises a puncture assembly and a suture assembly, wherein the puncture assembly comprises a puncture end and a puncturemandrel, the suture assembly is positioned in the puncture assembly, and at least one part of the puncture assembly can move in the puncture assembly; during suturing, an accommodating space is formedbetween the puncture end and the puncture mandrel, through the movement of the suture assembly, one end of a suture line penetrates through the tissue in the accommodating space. For the puncture core assembly and a puncture device with the puncture core assembly, a puncture hole does not need to be enlarged, the additional surgical instrument does not need to be increased, the puncture effect can be realized for establishing a channel, and an anastomat or other surgical operating instruments enter the body of a patient; the suturing of the puncture hole can be realized in the narrow puncturehole, and the suture effect is good; the puncture hole hernia caused by the puncture hole of the minimally invasive surgery can be effectively avoided, the pain of patients is effectively alleviated,and the postoperative rehabilitation of the patients is facilitated.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a puncture core assembly and a trocar with the same, belonging to the field of medical equipment. Background technique [0002] In abdominal examination, abdominal surgery and other minimally invasive or surgical operations, trocar is an indispensable surgical instrument. The trocar can establish an access channel in the abdominal wall of the human body so that staplers or other surgical instruments (such as endoscopes, scissors, guide wires, catheters, filters, stents, etc.) To control the pneumoperitoneum required for surgery for examination or surgical manipulation. [0003] In minimally invasive laparoscopic medical surgery, if a lesion is found in the human body and requires surgery or resection, it is necessary to perform pneumoperitoneum in the human abdominal cavity during the operation. Establishing pneumoperitoneum is an important operation process of laparoscopic surgery. In ...
