Ergonomic analysis of the dimension of a precision tool handle: a case study

Abstract Minimally Invasive Surgery (MIS) techniques have been rapidly introduced into routine surgical practice and the displacement of traditional surgery by MIS surgery techniques is becoming more frequent because of the advantages it has for the patient, both during surgery as in their postoperative recovery. However, the prolonged procedures and the high technological complexity required by the techniques as well as the use of inappropriate equipment and surgical instruments entail a number of disadvantages for surgeons. In the last years, research into this kind of operation has focused on assessing their cost-effectiveness relationship, while there have been fewer studies devoted to ergonomics in the field of surgical instruments. The aim of this study is to improve the ergonomic design of the handle of laparoscopic surgical clamps upon the basis of anthropometric criteria
