A study explores how 3D printed surgical models can improve the training of medical students in suturing techniques. Research conducted at Zhejiang Provincial People’s Hospital shows promising results for enhancing surgical education through innovative training methods.
The effectiveness of conventional training methods for surgical students often falls short, leaving many feeling unprepared for hands-on surgical roles. Traditional pads have been the primary training tool for many aspiring surgeons, but recent initiatives have prioritized simulation and practical experience to bridge this educational gap.
A pivotal randomized cohort study involved sixteen sixth-year medical students who were divided to receive training on either traditional suturing pads or innovative 3D printed intestinal models. The study took place between February and April 2024 and aimed to assess not only the students’ surgical performance but also their interest and engagement with the field of surgery.
The study's findings were significant. While initial performances showed no substantial differences between both groups, results from standardized exams indicated notable advantages for those using the 3D models. Participants who trained with the 3D models demonstrated higher performance scores and more efficient surgical times during later assessments compared to their counterparts reliant on traditional training pads.
The research methodology was thorough. After initial training on basic skills, participants underwent four weeks of open and laparoscopic surgical training, with performance evaluated using various assessments. The objective measures confirmed the superiority of the 3D models, leading to enhanced skills, reduced time for surgical procedures, and increased interest and confidence among students.
Post-training surveys indicated a substantial uptick in students' enthusiasm for surgery and technical skills training following their experience with the 3D printed models. One influential quote from the authors of the study noted, “Realistic 3D-printed models benefit surgical training, expected to become integral in teaching operative skills and techniques to medical students.”
Such models are created using advanced 3D printing technology based on actual patient data, providing students with lifelike anatomical representations and the tactile feedback necessary for surgical training. This approach allows for repeated practice and mastery over surgical techniques before encountering real patients.
The study received ethical approval and highlights the potential of 3D printing technologies to redefine surgical education. Since students are often limited by the confines of traditional training methods, incorporating these models might help demystify complex surgical procedures.
The authors call for institutional changes to incorporate 3D printed surgical models more broadly as educational tools. With the advance of digital design tools and printing technology, feasibility and affordability are increasing, making it viable for medical schools to adopt these training methods.
Future research will be necessary to investigate long-term outcomes for students trained with these modern methods, but the evidence already suggests substantial room for improvement over traditional practices. By integrating 3D models, surgical education can potentially produce more competent, confident surgeons ready for the challenges of clinical practice.
