A suture assembly for suturing a puncture hole

Abstract

A suture assembly for suturing a puncture hole includes a suture, a first element, and a rotatable second element. The second element has a first position and a second position, and the second elementis rotatable between the first position and the second position. The second element moves synchronously with the proximal end of the suture below the skin layer and from the first position to a second position and expands the suture. After the first element penetrates the tissue, the suture is accommodated and guided to move in the direction opposite to the direction of the penetrate tissue so asto drive the suture out of the tissue on the opposite side of the puncture hole, thereby suturing the puncture hole by the suture. According to the suture assembly of the invention, the suture of thepuncture hole can be realized, and the suture of the whole skin layer can be realized, and the suture effect is good. The suture assembly can effectively avoid the puncture hole hernia caused by theminimally invasive 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 suturing assembly with the function of suturing puncture holes, and belongs 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 laparoscop...

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
