Abstract
A suturing device comprises a rod with a spring needle attached to an insertion end thereof. The spring needle is housed inside of an outer guide tube for insertion into an opening in biological tissue to be sutured. After the spring needle is deployed from the outer guide tube, the rod and hence the coiled spring are then rotated to thread the spring needle up through the biological tissue to the surface. The suturing device is then removed leaving a suture in place. The method of using the device comprises introducing the compressed spring needle with a suture attached thereto into the opening in the biological tissue. An operator then rotates the spring needle to thread the spring needle to the surface of the biological tissue. After removing the spring needle the suture is tied.
