Tissue adhesives are commonly used throughout medicine for wound closure, but their application remains limited in comparison to conventional devices such as staples or sutures.

Although wounds closed with glue have reduced healing times and are less prone to infection, barriers such as the material’s low flexibility and potential toxicity have limited the market for tissue adhesives.

However, researchers at the Israel Institute of Technology and Harvard Medical School have developed a hot glue gun for wound closure that improves on the strength and elasticity of currently marketed tissue adhesives. This simple and straightforward device, which is designed to release glue that quickly solidifies when applied, could be a safe and effective alternative to suturing.

The wounds that benefit the most from modern tissue adhesives are lacerations or incisions that occur in less mobile areas of the body. Tissue adhesives do not hold up as well as sutures for high-tension wounds but are cost-effective, can be quickly applied, and reduce the risk of infections. The glue gun device, which uses special bio-compatible glue, could provide physicians with the unique benefits of traditional tissue adhesives as well as the treatment flexibility of sutures and staples.

The global market for tissue adhesives is valued at almost $1.2 billion and has been exhibiting modest growth. Minimally invasive wound closure remains an attractive option for medical practitioners and patients alike, and a new approach to tissue adhesion could invigorate this market. The market has been trending towards alternative glue formulations from the traditional cyanoacrylate-based adhesives, and a hot glue gun-based device could be an innovative disruptor for wound care.
