Description

Technical Field

[0001] The utility model relates to the technical field of puncture hole sealers, in particular to an abdominal wall puncture hole sealer and a conveyor thereof. Background Art

[0002] The puncture hole is a puncture hole made by the laparoscopic puncture device on the abdominal wall, which is a type of abdominal surgical incision. If the puncture hole is not closed properly, a puncture hernia will occur. A puncture hernia is mainly caused by the puncture hole in the abdominal wall not being closed tightly, puncture infection, and puncture fissure.

[0003] Except for the rectus abdominis, the fibers of the various layers of muscle, fascia, and sheath of the abdominal wall generally run horizontally. Longitudinal incisions are bound to cut these fibers. When suturing these tissues, the sutures are prone to slipping between the fibers; the sutured tissues are often subject to the lateral traction of the muscles and are prone to puncture and tearing. In addition, since the puncture holes are small, usually with a diameter of 5 to 15 mm, the suturing operation is very difficult. If the wound edges are forcibly pulled together during suturing, causing tissue tearing, it will also lead to the occurrence of puncture hernia. According to data, if the incision is healed by the first intention after abdominal surgery, the incidence of incisional hernia is usually less than 1%, but if the incision is infected, the incidence can reach 10%, and the incidence can even be as high as 30% for wounds. Some literature points out that puncture hernia is not only prone to complications such as intestinal obstruction and incarceration necrosis, forcing patients to undergo emergency surgical intervention, but also increases the mortality rate of patients.

The abdominal wall puncture hole sealer is pre-installed in the conveyor before use, and enters the abdominal cavity through the puncture device when used.

[0042] The working principle of the utility model is: when closing the abdomen after the laparoscopic surgery, insert the conveyor pre-installed with the abdominal wall puncture sealer and matched with the inner diameter of the puncture device into the puncture device to the limit position. Then remove the card 33 at the top of the lifting rod 20, and then pull the puncture device and the conveyor out of the puncture hole. Then lift the lifting rod 20 until you feel resistance (make the closing disk 10 close to the abdominal wall), and record the length (scale) of the lifting rod 20 in the puncture hole. Then adjust the long axis of the cross section of the lifting rod 20 to be parallel to the surgical incision line, squeeze the incision epidermis to make the incision close tightly, and at the same time forcefully lift the lifting rod 20 upward to make the barbed nail 12 penetrate the abdominal wall tissue, and the scale shows that the length of one nail is shortened to fully penetrate. Then push the lifting rod 20 down and do not move, confirming that the closing disk 10 is fixed. Rotate the lifting rod 20 to the position of disengagement from the closing disk 10, and finally pull out the lifting rod 20.
