Description

Technical Field

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

[0002] A 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 trocar site hernia (TSH) will occur. Trocar site hernia is mainly caused by poor closure of the abdominal wall puncture hole, infection of the puncture hole, 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 tearing. In addition, since the puncture is small, usually only 5-15mm in diameter, the suturing operation is very difficult. If the wound edge is forcibly pulled together during suturing, causing tissue tearing, it will also lead to the occurrence of puncture hernia. Due to obesity, advanced age, diabetes, incision infection, long-term drainage and other reasons, the puncture will be loose, resulting in poor healing of the puncture, and increasing the incidence 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%; if the wound is open, it can even be as high as 30%. 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.
