Influence of needle holder jaw configuration on the biomechanics of curved surgical needle bending

Search for a scientific basis for continuous suture closure: a 30-yr odyssey

Continuous percutaneous and dermal suture closures have an important role in the approximation of long, linear lacerations in the emergency department. This report documents the scientific basis for these continuous closure techniques. In addition, a detailed description of these surgical closure techniques is presented.

Mechanical performance of surgical needle holders

A new quantitative measurement of surgical needle holder performance has been described that records the forces (clamping moment) applied by the needle holder jaws to curved surgical needles. This test has been used to determine the applied clamping forces of four different surgical needle holders made by one manufacturer. By relating the magnitude of the clamping moment of needle holder to the resistance to bending of curved surgical needles, we propose a new scientific basis for selecting surgical needle and needle holders for wound closure.
