“…The insect family Formicidae of the order Hymenoptera is the main source of inspiration in bio-inspired clamps. Brito et al [120], [121] designed a surgical clamp inspired by the Atta laevigata (Smith) ant. The aim of the clamp is to make placement and removal of the clamp more efficient and less traumatic for the patient.…”

“…The working mechanism of the surgical clamp mimics the ant mandibles: (1) an external compressive stress must be applied to the levers to open the clamp, (2) the surgical clamp can penetrate the skin due to elastic forces, (3) the clamp falls by itself after healing, which relieves the inconvenience of the clip removal process. Brito et al [120] studied the mandibles of the A. laevigata ant to present a selection of candidate biocompatible materials for surgical clamps. The biological materials of insects' mandibles can be correlated with polymers because the mandibles are composed of waxes, polysaccharides, and proteins.…”

Insects are important agents in ecosystems. Their diverseness and developed coping mechanisms also make them interesting for direct application and as a source of inspiration in medical engineering. We summarized the main contribution of insects in biomedical applications. Medical centers in North America, and Europe use fly larvae for maggot therapy to remove necrotic tissue, decrease infection risk, and improve wound healing. Ant mandibles are used as a suturing technique by African tribes and as sources of inspiration for surgical clamps. Both the mosquito fascicle and the wasp ovipositor are sources of inspiration for the design of medical needles. Herein, a new research field called "entomomedical engineering," is proposed. We define entomomedical engineering as the branch of engineering that uses insects either directly or as a source of inspiration to design and develop medical treatments or instruments. In addition, we want to emphasize the importance of preserving insects because of their function in the ecosystem, medicine, and medical engineering.
