Trocar site suturing device

摘要

A device for suturing closed laparoscopic trocar sites to reduce the incidence of incisional herniation. A pair of needles, hollow and having an eyelet adjacent the pointed end, are secured to a clip which may be fastened over a trocar sheath. The clip is then forced to slide down the sheath and the two needles penetrate the fascia and underlying muscle surrounding the hole formed by the trocar. The needles may also be spread somewhat after passing within the skin in to gain a better bite on the tissue surrounding the trocar sheath. A suture is then threaded down through one hollow needle and passed through the eyelet of the second needle, utilizing the laparoscope and a second accessory sheath. When the device is then withdrawn, the suture remains, passing through the peritoneum, muscle and fascia and may be tightened to close the site upon removal of the sheath.
