| Research Abstract |
Suturing motion was modeled to develop the basic surgical technique transfer system. Surgical needle handling motion by surgeon was recorded from 4 direction using 4 CCD cameras. A surgeon sutured optionally, being conscious of shallow, deep and middle depth. Suturing motion was analyzed on position and velocity of needle-holder by three-dimensional coordinate measurement software. In results, surgical needle handling motion was composed of prick motion by surgical needle and pull up motion of the needle and thread. The prick motion was divided into straight motion that was pierced in tissue, and curve motion that was operated along curvature of the needle. Suture depth in the prick motion was depended on the angle and length of the straight motion. In the pull up motion, the angle and velocity of the needle and thread was constant.
