Safer trocar insertion for closed laparoscopic access: ex vivo assessment of an improved Veress needle

摘要

Laparoscopic surgery is widely practiced surgical technique in the modern surgical toolbox. The Veress needle insertion technique, while faster and easier, is associated with higher rates of iatrogenic complications (injury to internal organs, major blood vessels, etc.), morbidity and even mortality with a reported overall risk of 0.32 % during surgical interventions. In order to increase the safety and ease of closed insertion technique, we designed and tested an improved prototype of the Veress needle.
