A simple, inexpensive method for precise application of cyanoacrylate tissue adhesive

Area of Science:

• Surgical Innovation
• Wound Management
• Biomaterials

Background:

• Cyanoacrylate tissue adhesives are widely used for skin wound closure.
• Low viscosity of adhesives often leads to uncontrolled flow, hindering precise application.
• Existing application methods can be challenging for accurate placement.

Purpose of the Study:

• To describe a simple technique for precise application of cyanoacrylate tissue adhesives.
• To present an improved method for applying Histoacryl for wound closure and skin grafting.
• To address the challenge of adhesive flow and improve application accuracy.

Main Methods:

• A "blue" needle was fitted to the tip of a Histoacryl tube.
• The modified applicator was used for precise delivery of cyanoacrylate adhesive.
• The technique was evaluated for accuracy and control in application.

Main Results:

• The needle-tip technique allowed for precise, fine, and predictable application of the adhesive.
• The method significantly reduced adhesive "running" to adjacent undesired areas.
• A fast and effective method for skin graft inset using the technique was demonstrated.

Conclusions:

• Fitting a needle to the Histoacryl tube tip offers a simple and effective solution for precise cyanoacrylate adhesive application.
• This technique enhances control, reduces waste, and improves outcomes in wound closure and skin grafting.
• The described method is inexpensive and easily implementable in clinical practice.
