Many surgeons experience pain or discomfort when performing laparoscopic (minimally invasive) surgery. After observing at operations and interviewing the surgeons I found out that most of the discomfort is caused by the current instruments: they force the hand into unnatural movements and positions, and they repeatedly apply pressure on the same small contact areas on the hand. Over 12% of surgeons experience frequent pain and discomfort when performing minimally invasive surgery. In the long term this may lead to physical injury.

I chose to redesign the handle while still allowing the attachment of currently used instrument pieces. I closely analyzed the natural movement of the hand and in which positions and directions the most force can be applied. In the new design the lever moves at an angle and has a rotating top, allowing it to follow the natural movement of the hand.
