“…Intermittent irrigation and suction disturb workflow and prolong operative time, require an assistant, 2 and can increase risk of arterial thrombosis from vessels being drawn into suction devices. We have demonstrated the use of a novel smart background with built-in suction and irrigation that enhances the speed of conducting the microsurgical anastomosis, with better clarity of vessels and less interruptions and wiping events in a rat femoral vessel model.…”

Summary: Microvascular anastomoses can be challenging to perform when edematous fluids and blood continuously flood and compromise the field of view. Intermittent irrigation and suctioning disturb workflow, require an assistant, and can increase risk of arterial thrombosis from vessels being drawn into suction drains. The authors developed and patented a novel three-dimensionally printed background device with microfluidic capabilities to provide autonomous, continuous irrigation and suction to optimize operator autonomy and efficiency. The authors tested this in a rat femoral vessel model. Twelve end-to-end anastomoses were performed by two senior microsurgeons [six conventional, six suction-assisted background (SAB)] in a rat femoral artery model. The primary outcome was time taken to complete the anastomosis. Secondary outcomes included the validated Structured Assessment of Microsurgery Skills (SAMS) score and the total number of “wiping” events to obtain field clarity. Each procedure was recorded, and videos were independently rated by two blinded experts using the SAMS score. Time taken to complete the anastomosis was greater in the conventional group compared with the SAB group (741.7 ± 203.1 seconds versus 584 ± 155.9 seconds; P = 0.007). The median SAMS score was lower in the conventional group compared with the SAB group (32.3 ± 1.4 versus 38.3 ± 1.5; P = 0.001). The median number of wiping events was significantly greater in the conventional group compared with the SAB group (13 ± 2.2 versus 1.7 ± 1.2; P < 0.001). The authors show that a novel microfluidic background device allows continuous irrigation and suctioning without the need for an assistant, optimizing the efficiency of the microvascular anastomosis. Clinical Relevance Statement: The authors have designed a novel, patented, three-dimensionally printed microsurgical background device that provides continuous irrigation and suction, reduces operative time, and provides better vessel clarity during a microsurgical anastomosis compared to standard background.

“…Currently, the assistant is required to provide suction and the contrast between the vessel and its surroundings needs to be enhanced. 3 An addition to the microsurgeon's repertoire has been the use of microvascular background sheets that provide adequate contrast of the vessel relative to its surroundings during the anastomosis technique and has been found to improve the accuracy of vessel alignment. 4 Nambi et al, provided an in-house and cost-efficient solution to alleviate some of the technical burden of the anastomosis operation by providing continuous suctioning during microvascular anastomosis with the use of a paediatric feeding tube covered in a gauze layer.…”

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.
