Technical Field
The invention belongs to the technical field of surgical instruments, and particularly relates to a puncture sheath with a suture function.
Background
Laparoscopic surgery is a newly developed minimally invasive surgical procedure, so that many of the past open surgery has now been replaced by endoluminal surgery, greatly increasing the surgical options. With the development of laparoscopic techniques, laparoscopic surgery is accepted by more and more doctors and patients. The laparoscopic surgery must be performed by creating a working channel through a puncture sheath (trocar) in the abdominal wall and then using a specially-made elongated surgical instrument to perform the same procedure as the open surgery under television monitoring to achieve the same surgical result. At present, the puncture sheath has a specification of 5-12mm in diameter, and generally, for the puncture hole of the abdominal wall larger than 5mm, the peritoneum and fascia layers must be sutured to prevent incision bleeding and reduce the incidence rate of incision hernia. While conventional arcuate needle suturing methods cannot be performed for such small incisions, particularly for obese patients, straight needle suturing methods cannot correspond to the tissue on both sides of the small incision due to the lack of necessary guiding and positioning means, and it is difficult to achieve the desired suturing result.
