Piercing core assembly with suturing function and trocar

Abstract

The invention discloses a puncture core assembly, comprising a puncture assembly and a suturing assembly. The puncture assembly comprises a puncture end and a puncture core rod. The suturing assemblyincludes a first element and a movable second element. The second element having a first position and a second position. The puncture end drives the proximal end of the suture to below the skin layer,the second element moves from the first position to the second position and expands the suture, and the first element penetrates the tissue and drives the suture out of the tissue on the opposite side of the puncture hole so as to realize the suture of the puncture hole by the suture. The puncture core assembly and the puncture device with the puncture core assembly can not only realize the puncture function, but also realize the suture of the puncture hole, and can realize the suture of the whole skin layer, and the suture effect is good; the puncture core assembly and the puncture device with the puncture core assembly can realize the puncture function and the suture of the puncture hole and the whole skin layer. It can effectively avoid the puncture hole hernia caused by the minimallyinvasive operation, effectively reduce the pain of patients, and is conducive to postoperative rehabilitation of patients.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a puncture core assembly with a suturing function and a puncturer thereof, 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 lap...

AI Technical Summary

Problems solved by technology

When it is necessary to suture the puncture hole of a patient, especially the puncture hole of an obese patient, only a stapler specially used for suturing the puncture hole can be used, but this requires additional surgical instruments, the suturing cost is high, and there are many surgical instruments and inconvenient operation

And, the stapler that specially sutures the puncture hole has a complex structure and is inconvenient to use

[0005] The existing puncture device can only realize the puncture function, and does not have the function of suturing the puncture hole. Therefore, it is urgent to make improvements on the basis of the existing design in order to achieve a more ideal effect
