Surgery has become difficult and less reliable due to the effects of microgravity, resulting in a wavering hand and invasive surgery process. The Micro-Cutter is a device that is a combination of an accurate dissector, creating the perfect straight line, as well as attaching conveniently on a limb to stabilize control and accuracy. Its intricate woven pattern allows for the easy contraction and expansion of the innovation to adapt to all limb sizes and strap on securely. Similar to a sliding door, the knife is aligned to easily slide straight across with the guidance of the premade slit in the device to ensure the surgical area is correct. In the case of an emergency, one could operate on themselves without reliance on another person or device. This is critical when people and supplies are limited in an unknown world, where diseases are not yet discovered and the effects of radiation are high.
