Surgical Zippers

In 1985, zippers for stitches were announced by Dr. H. Harlan Stone this day. The surgeon had used zippers on 28 patients, on whom he thought he might have to re-operate, because of internal bleeding following initial operations. The zippers which lasted between five and 14 days, were then replaced with permanent stitches. Current types of surgical zipper are self-adhesive in application and can be applied to both outpatients and inpatients. Uncomplicated wound inspection is possible from the third postoperative day. However, it is possible earlier with manual support to either side of the wound.
