MicroSUCI: A Microsurgical Background That Incorporates Suction Under Continuous Irrigation

Abstract

The microsurgical anastomosis is integral to the success of autologous free tissue transfer. Successful performance of this procedure relies strongly on operator dexterity, which can be made more challenging when blood and oedematous fluids obscure the field of view. Workflow is impeded by intermittent irrigation and suctioning, necessitating presence of an assistant, with risk of arterial thrombosis, from vessels being drawn into suction drains. To negate these current disadvantages and minimise the barrier of entry to microvascular operations, we designed, manufactured and patented a novel 3D printed microsurgical background device with microfluidic capabilities, that allow continuous suction and irrigation as well as provides platforms that enable multi-angle retraction to facilitate operator autonomy. This was validated in an ex-vivo model, with the device found to be superior to the current standard. We believe that this will have major applicability to the improvement of microsurgeon.
