Description

A special wire needle for laparoscopic minimally invasive surgery of indirect hernia in children

technical field

The utility model belongs to the technical field of medical instruments, in particular to a laparoscopic guide wire needle specially used for minimally invasive surgery on indirect hernia in children.

Background technique

Laparoscopic minimally invasive surgery for indirect inguinal hernia in children has the advantages of simple operation, less trauma, quick postoperative recovery, and no postoperative scar, and is increasingly recognized by pediatric surgeons and patients. At present, the more common and convenient method is to use a self-made wire needle to complete the high ligation of the internal ring opening of the indirect hernia. The operation requires two needle insertions, which need to be inserted through the same skin incision, and then enter the extraperitoneal space through the same channel. If the needle cannot be inserted twice into the extraperitoneal space through the same channel, it may cause the fascia muscularis tissue to be located in the ligature knot, so the muscle fascia may be damaged and necrotic after ligation, and the ligature knot may become loose, which may lead to the recurrence or formation of an indirect hernia Hydrocele. However, the guide wires currently used cannot ensure that the two needles enter from the same channel, which poses a challenge to the operator. Therefore, it is urgent to invent a special guide wire to reduce the difficulty of the operation, shorten the operation time, and avoid surgery. Posterior indirect hernia recurrence.

Contents of the invention

Aiming at the above-mentioned problems existing in the prior art, the utility model provides a laparoscopic infantile indirect hernia minimally invasive surgery guide wire, which can ensure that the guide wire easily enters the extraperitoneal space through the same channel, shortens the operation time, and reduces recurrence of indirect hernia.

The utility model is realized through the following technical scheme: a laparoscopic infantile indirect hernia minimally invasive surgery guide wire, which is characterized in that it includes a wire needle body and a wire needle sleeve, and the wire needle body includes a needle head and a needle Rod, needle head and needle rod are integrated structure, the needle rod is a solid structure, the needle head is an arc-shaped flat head structure, the needle head is provided with a threading hole, and a silk thread is arranged in the threading hole, and the guide wire needle body and the silk thread jacket are placed There is a guide wire cannula.

The threading hole is set on the needle at a distance of 2 mm from the front end of the needle; the wire needle sleeve is made of hard plastic.

The beneficial effects of the utility model are: the utility model is a laparoscopic infantile indirect hernia minimally invasive surgery guide wire, which makes the operation more simple and easy, and can be completed through a single hole without the need for additional operating equipment, so trauma It is small and can ensure that the wire needle can easily enter the extraperitoneal space through the same channel, which shortens the operation time and reduces the recurrence of indirect hernia.

Detailed ways

As shown in Figures 1-3, the utility model includes a wire needle body 1. The wire needle body 1 includes a needle head 11 and a needle bar 12. The needle bar 12 adopts a solid structure, and the needle head 11 and the needle bar 12 are integrated. structure. The needle 11 is designed with an arc-shaped flat head structure to facilitate the stripping of the surrounding tissue of the hernia sac and avoid damage to the spermatic cord blood vessels and the vas deferens. A threading hole 2 with a diameter of about 1 mm is provided on the needle 11 at a distance of 2 mm from the front end of the needle. The threading hole 2 can pass through No. 4 silk thread 3 . 4. It is made of hard plastic, and the end intended to enter the abdominal wall is slightly closed to reduce the resistance of entering the abdominal wall. It can be used once or repeatedly.

Utilize the operation procedure of the utility model as follows: insert a laparoscope at the incision of the umbilicus, incise the skin 2 mm at the projection of the body surface above the inner opening of the groin, and place a wire needle under direct vision of the laparoscope. The guide needle with cannula and silk thread is inserted from the above skin incision for the first needle insertion: the guide needle sneaks around the inner half circle in the extraperitoneal space of the internal opening of the indirect hernia, crosses the vas deferens and spermatic vessels, and punctures the peritoneum Enter the abdominal cavity, twitch the wire needle to form a coil structure at the end of the silk thread; at this time, push the wire needle sleeve into the extraperitoneal space, in order to reduce the resistance of the wire needle sleeve entering the abdominal wall, the end of the wire needle sleeve that is intended to enter the abdominal wall can be placed Close slightly to make it fit closely with the wire needle. When the wire needle sleeve enters the extraperitoneal space, prepare to withdraw the wire needle: insert the laparoscope into the coil and press against the abdominal wall on one side, pull out the wire needle, and wire the wire coil remain in the abdominal cavity. Needle insertion for the second time: the wire needle with another silk thread is accurately entered into the extraperitoneal space for the second time along the wire needle sleeve through the same channel, at this time, the wire needle sleeve is withdrawn, and the wire needle is used to continue to peel off the inner orifice of the indirect hernia Half a circle, enter the abdominal cavity at the first puncture of the peritoneum, and enter the silk coil inserted for the first time, extend the laparoscope into the coil formed by the second silk thread, and place the wire against the abdominal wall on one side The needle is pulled out, the silk thread inserted for the first time is pulled out outside the body, and the silk thread inserted for the second time is pulled out of the abdominal wall and knotted to complete the ligation of the inner ring.

Except the technical characterictic described in above-mentioned instructions, all are the known technology of those skilled in the art.
