Abstract

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 When the device is then withdrawn, the suture remains, passing through the peritoneum, muscle and fascia and may be tightened to close the site upon removal of the sheath.

Claims

1. A device for suturing trocar sites closed, comprising:

(a) a first needle and a second needle, each having a pointed end and a non-pointed end, said first needle being hollow, said second needle having an eyelet passing therethrough adjacent said pointed end; and

(b) means for receiving said needles and slidably mounting said needles in a parallel, spaced apart relation on a trocar sheath.

2. The device for suturing trocar sites as recited in claim 1 wherein said mounting means comprises a substantially semi-circular ring.

3. The device for suturing trocar sites as recited in claim 2 wherein said needles are affixed on opposite sides of said ring.

4. The device for suturing trocar sites as recited in claim 3 wherein said needles are pivotally affixed to said ring, said needles having a retracted position and an extended position.

5. The device for suturing trocar sites as recited in claim 4 wherein said needles are biased to said retracted position.

6. The device for suturing trocar sites as recited in claim 5 wherein said device is fabricated from stainless steel.

7. The device for suturing trocar sites as recited in claim 5 wherein said ring is fabricated from plastic.
