MicroSUCI: A Microsurgical Background That Incorporates Suction Under Continuous Irrigation

Area of Science:

• Microsurgery
• Biomedical Engineering
• Tissue Engineering

Background:

• Microsurgical anastomosis is critical for autologous-free tissue transfer success.
• Dexterity is key, but obscured views from fluids impede performance.
• Current methods require assistants and risk vessel damage during suctioning.

Purpose of the Study:

• To design and validate a novel 3D-printed microsurgical device.
• To overcome limitations of current microsurgical techniques.
• To enhance operator autonomy and minimize procedural barriers.

Main Methods:

• Designed and patented a 3D-printed microsurgical device with microfluidic capabilities.
• Integrated continuous suction, irrigation, and multiangle retraction platforms.
• Validated the device in an ex vivo model compared to the current standard.

Main Results:

• The novel device demonstrated superior performance compared to the current standard.
• Continuous suction and irrigation maintained a clear field of view.
• Multiangle retraction facilitated greater operator autonomy.

Conclusions:

• The 3D-printed microsurgical device effectively addresses challenges in microsurgical anastomosis.
• This innovation has significant potential to improve microsurgeon outcomes.
• The device offers a solution for enhanced microsurgical procedures and training.
