Children's processus vaginalis high ligation trocar under a kind of laparoscope

Technical field

The utility model relates to children's processus vaginalis high ligation trocars under a kind of laparoscope.

Background technique

Laparoscopic surgery is exactly the operation carried out using laparoscope and its related equipment, and it is minimally invasive to be that a new development is got up Method, laparoscopic surgery have the characteristics that wound is small, it is fast to restore, scar is small, Minimally Invasive Surgery is surgery hair compared with traditional operation It the general trend of exhibition and pursues a goal.In general, the operation of most of general surgery, laparoscopic surgery can be completed.

It is also that pediatric laparoscopic indirect inguinal hernia hernical sac high position knot is being carried out using laparoscopic surgery when treating children inguinal hernia It when art of pricking the hand, needs to use veress needle and hernia needle simultaneously, hand could be completed twice even if a kind of needle is used only and is also required to acupuncture treatment Art, therefore, the position having an acupuncture treatment twice at the time of surgery, not can guarantee unanimously, and the surface of a wound is easily caused to expand, and influence postoperative beauty.

Reaction of laparoscopic hernia sac high ligation is the new art formula of children's herniorrhaphy, sufficiently show minimally invasive surgery advantage it Traditional operation approach is changed, dissection groin pipe is not needed, avoids the cicatricial adhesion of iliac region.With hysteroscope technology Mature, instrument to continuously improve, laparoscopic repair for indirect inguinal hernia in children and the hydrocele of tunica vaginalis will gradually replace traditional open surgery.Mesh It is preceding almost the same using the operation principle of laparoscopic high ligation of hernial sac, it is guided outside downlink hernia inner ring food film by laparoscope It moves under water suture.Three holes or two hole operations are required mostly, and a hole is hysteroscope hole, and a hole is operation pincers hole: groin pipe puncture needle Peritonaeum moves under water and separation and assists that silk thread is sent into and is taken out outside collar extension in the auxiliary downlink of abdominal cavity operation pincers.Or with single hole abdominal cavity Mirror guides collar extension prong suture in downlink hernia, because of sharp internal organs such as blood vessel easily accidentally injured under stomach wall of needle point and inconvenient.

Currently, Chinese patent discloses a kind of multi-functional veress needle, application number 201520621420.1 comprising outer needle, Inner core, casing, outer adapter and inner core connector, the outer needle and inner core are hollow structure；One end of the outer needle is fixed on In outer adapter, the other end is beveled point；One end of the inner core is fixed on inner core connector, and the other end is obtuse body, institute The side for stating obtuse body is equipped with slanting notch.Chinese patent Multifunctional hernia needle includes outer needle, inner core and valve, described outer Needle and inner core are hollow structure, which is characterized in that further include fixed screw, spring, casing and dual-cavity before inner core spring The end of spring fixed screw, the outer needle has spring cavity, and the inner core is placed in the outer needle, and the front end of inner core is arc The obtuse body of protection face is equipped with circle concave empty slot close to the side of the obtuse body end on the inner core.

It is hollow structure that above-mentioned two patent, which shares characteristic as outer needle and inner core, and inner core is obtuse body, due to outer Needle and inner core are hollow structure, therefore its face area is larger, during operation caused by wound it is also larger, influence postoperative beauty It sees.Since inner core is obtuse body, in use, needing to be pierced into skin histology by the needle point of outer needle, and pass through the needle of outer needle Point gradually pierces all layers of abdominal wall tissue, reaches preperitoneal space, and outer needle is located at except inner core, thus caused by the surface of a wound it is larger, It is postoperative also to influence beauty.

The reason of core designs are obtuse body, there are two: 1. prevent from cutting off on silk thread；2. contacting tissue, group will not be stabbed It knits, shields.It needs as directly done puncture using inner core using biggish strength, and has silk thread not existing as hindering It is real.

Currently, lacking in the market, a kind of surface of a wound is smaller, and ligation trocar convenient to use.
