Surgical instruments
for gender equality

It is a set of the most used surgical instruments for surgery but with a new and fresh design that combines usability, aesthetics, functionality and a deep focus on gender equality.
The original design of this kind of tools is ancient and was intended only for men, so women nurses and doctors face different obstacles when using them, besides, the total proportion of practicing female doctors will grow dramatically in the coming years, which means that the number of people affected by ergonomic, usability and biomechanical problems will also increase if something is not done now.
This project consists of the redesign of forceps and surgical scissors using a user-centered design approach, ergonomic factors.

The intrinsic characteristics of these instruments offer any user the possibility that the tool adapts to their hands regardless of the size. In addition, they were not only improved ergonomically, but also biomechanically: the redesign of the Forceps allows a better grip and a greater pressure area, which helps to reduce the force required to close them.
Ergonomically speaking, the 5th-percentile woman's hand is considerably smaller than the 95th-percentile man's hand in every dimension. The differences are even more pronounced at the 1st and 99th percentiles, where thumb widths, for example, range from a mere 0.6 to 1.2 in. twice as wide.

Strength differences are also dramatic.4 The 2.5th-percentile woman's squeezing grip strength, for example, is 53 lbf, while the 97.5th-percentile man can exert 147 lbf. For the same individuals, fingertip pinch strengths range from 7.5 to 30 lbf. As a rule, designers can figure that the average woman's hands, and upper extremities in general, are about half as strong as the average man's.

A recent survey sponsored by Ethicon collected hand size and strength data from the participating surgeons. The data suggest that almost 50% of all surgical instruments feel too large to grip comfortably and feel improperly contoured to the hand. Moreover, respondents with particularly small hands opined that 80–90% of all surgical instruments are not ergonomically suitable for their particular use.
This is why it is necessary to redesign the objects, proposing solutions and gender equality.
