Minimally invasive suture guiding device for treatment of oblique hernia in children and using method

Abstract

The invention relates to a minimally invasive suture guiding device for treatment of oblique hernia in children and a using method. The device comprises a linear guide rod having a cavity, a first arc-shaped guide rod, a second arc-shaped guide rod and a third arc-shaped guide rod; one end of the linear guide rod is communicated with the first arc-shaped guide rod, and the other end of the linearguide rod is provided with a valve; the second arc-shaped guide rod is slidingly mounted in the first arc-shaped guide rod, the third arc-shaped guide rod is slidingly mounted in the second arc-shapedguide rod, and the radians of the three arc-shaped guide rods are all 120 degrees; after the second arc-shaped guide rod extends out along the first arc-shaped guide rod and the third arc-shaped guide rod extends out along the second arc-shaped guide rod, the three arc-shaped guide rods form a complete circular structure; interlocking devices are mounted on the three arc-shaped guide rods respectively. According to the suture guiding device, secondary needle insertion is avoided, secondary suture hooking is not needed, operation processes are simplified, the operation time is saved, surgicaltrauma is reduced, and surgical complications are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive lead wire device for children with indirect hernia and a use method thereof. Background technique [0002] Indirect hernia in children, commonly known as "hernia", is mostly caused by the failure of the peritoneal sheath to occlude during the descent of the testis during the embryonic period. It is a congenital disease and one of the most common diseases in pediatric surgery. Surgical treatment is the best treatment, the safest and most reliable, and the recurrence rate is also low. Traditional surgical methods cause damage to the anatomical structure of the inguinal canal and all layers of the spermatic cord, and the incision scars are obvious, and have been gradually replaced by laparoscopic minimally invasive surgery. Laparoscopic minimally invasive surgery requires high ligation of the inner ring, and the ligature needs to wrap around the inner r...

Problems solved by technology

At present, the wire needles used to guide the ligature are all straight needles, which cannot complete 360 ​​degrees around the inner ring at one time: the wire needle with the ligature must first go around the inner ring 180 degrees and then puncture the peritoneum so that the guide wire stays In the original position; then withdraw the wire needle, wind it 180 degrees in the opposite direction, hook the guide wire, and withdraw the wire needle to complete the 360-degree circle around the inner ring mouth of the ligation line

This method not only requires cumbersome operation steps, but also requires a second needle insertion; it also requires high accuracy and stability when hooking the guide wire, and sometimes it takes repeated attempts to hook it, which prolongs the operation time; more importantly, It is necessary to puncture the peritoneum to keep the guide wire in place, which significantly increases the surgical injury
