Puncture core assembly and puncture unit provided with same

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.

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 ...

AI Technical Summary

Problems solved by technology

Existing trocars generally only have the function of puncturing, and a channel for instruments to enter and exit is established on the abdominal wall of the human body, so the puncture hole cannot be sutured; while the trocar with suturing function has a complex structure and is inconvenient to operate, and the size of the suturing space is a fixed value , the size of the suture space cannot be adjusted according to individual differences, which is not conducive to the postoperative rehabilitation of patients
