Although microgravity is not exactly the greatest place to sustain an injury (unless you are a dangerous microbe), many scientists are exploring new ways of conducting surgery in a weightless environment.
While a space doctor will be needed to help mend the wounds of astronauts, they may choose to use lasers to seal the wound instead of medical stitches.
Since regular earthly stitches are composed of synthetic material and catgut, scientists may prefer using lasers as it would translate into one less item to pack (as well as one less requirement for a future space doctor).
