The Influence of Hand Controls on Nurses' Operation in Emergency Surgery

This study is based on the effects on human joint angles caused by the different form of hand controls used by emergency nurses, using the evaluation methods of bad joint angles, come up with a reasonable height and angle range of controls. This study is divided into mainly two sections, in section one we used filming, to group the postures shown by ten emergency medics operating the common seen hand controls, and take the common seen posture to be the basis of the second section experiment. In section two, using 3D motion analysis system, to study the change of height and angle of control panels while fifteen women operate the five common seen hand controls in emergency (push button, big rotation knob, detent positioning knob, small rotation knob and toggle switch), and the effects on the body bending angle, elbow angle and wrist angle. At last using ANOVA analysis and regression function analysis to conclude a suitable control panel height and angle.
