Design and evaluation of 3D printed instruments for eye surgery

Additive manufacturing (AM) techniques continue to evolve pushing the boundaries of what is possible to print. For example, a strong benefit of 3D printing is that complex shapes can be printed in advanced, integrated 3D layouts without the need for assembly. However, one of the main drawbacks of 3D printing is the limited manufacturing accuracy, making it difficult to create tight tolerances in miniature high precision applications.

ReCleft is a reusable training simulator for surgeons


Cleft lip and/or palate (CLP) is the leading craniofacial anomaly affecting 1 in every 500-700 births. Gaining hands-on experience in cleft surgery can be difficult due to limited access within the infant oral cavity and the delicate tissues of the velum. Even minor errors may lead to complications with serious consequences for the patient. Globally, it is estimated that 250,000 infants are born with cleft lip and/or palate in low resource countries each year and it is estimated that a significant proportion are not repaired.

From digital to real: 3D printed model as new tool for modern general surgeons

From digital to real

by Professor Luigi Marano, University of Siena

Over the last years, the increase of intraoperative safety for patients and surgeons as well as the concept of “precision surgery” have been advocated as main topics of surgical research, particularly as regards the minimally invasive approaches. The proper patient-specific preoperative planning is mandatory to achieve a meticulous knowledge of the target anatomy, thus helping surgeons to imagine in their minds critical steps and potential complications of surgery. In addition, the more the anatomy is complex due to native anatomic anomalies, disease-related distortions or prior surgical interventions, the harder is the surgical strategy to apply especially in minimally invasive settings.
