Micro-needle scar prevention and treatment device

The utility model discloses a microneedle scar prevention and treatment device which comprises an elastic layer, a silica gel layer and a microneedle patch and further comprises a thermosensitive deformation capsule layer located between the elastic layer and the silica gel layer, and the thermosensitive deformation capsule layer comprises thermosensitive gel and an outer film. The temperature-sensitive gel is in a liquid state at normal temperature, has good fluidity, can change the state along with the shape of a scar on a scabed wound so as to adapt to the scar in any shape, is rapidly heated to about 37 DEG C under the action of body temperature after being applied to the skin, is cured, and applies uniform pressure to the uneven scar, so that the scar can be quickly cured. Meanwhile, pressure is applied to the microneedle array in the microneedle patch, so that the microneedle array can act on deep scar tissue. The vacuum adsorption layer is tightly attached to the skin, so that the microneedle patch is
