Inspired by origami, MIT made surgical adhesive to heal internal wounds

Inspired by origami, MIT researchers have developed a surgical adhesive that wraps around minimally invasive surgical instruments and completely heals wounds in narrow ducts inside the body.

Many surgeries today are performed with small incisions using miniature medical instruments with cameras to remove tumors or other repairs. Most physicians prefer minimally invasive surgeries because they are less painful and shorter in duration of treatment than open surgeries. One of the great challenges of minimally invasive surgery is the complete closure of wounds and incisions in the body.

MIT researchers use a surgical adhesive to solve this problem have made Inspired by origami, medical instruments gather around minimally invasive surgeries. With this feature, the glue can be sent to the airway, intestines and other narrow ducts to close the gaps. The adhesive looks like a folded piece of paper, but when it comes in contact with organs or tissues in the body, it transforms into a flexible gel, like contact lenses, that can be attached to the wound.

MIT’s invention has significant advantages over current medical adhesives. For example, the structure of this material is such that it is resistant to contamination after exposure to bacteria and body fluids. Another big advantage is that it decomposes and disappears over time. MIT researchers note that they have worked directly with physicians and surgeons to optimize the adhesive.

Researchers say the adhesive can be used to repair a variety of wounds, from cavities created after a colonoscopy to ligation of organs or repair of blood vessels damaged by trauma or surgery. This technology can also be used to repair cracks during minimally invasive surgery without the use of open surgery, at least for a short time.

This adhesive consists of three layers, the middle layer of which is made of hydrogel and a compound called NHS esters. After being exposed to a wet surface, this layer absorbs all the moisture and finds the ability to repair cracks by finding elasticity. Adhesive compounds also have the ability to form strong covalent bonds with tissue surface compounds and completely seal the gap.
