Overview

Brief Summary

The goal of this preclinical trial is to learn about the benefits and limitations of novel robotic devices for microsurgery, based on different levels of microsurgical experience. The main questions it aims to answer are:

Is robot-assisted microsurgery faster, better and more ergonomic than conventional microsurgery in a preclinical standardized setting?

Participants will perform microvascular anastomoses on 1.0-mm-diameter artificial silicone vessels using a conventional manual approach versus a novel robot-assisted approach. Researchers will compare the performance of novices, advanced participants and experts to evaluate the role of microsurgical experience when learning the new technique.

Detailed Description

Recent advancements in the development of robotic devices increasingly draw the attention towards the concept of robotic microsurgery, as several systems tailored to open microsurgery are being introduced. This study describes the combined application of a novel microsurgical robot, the Symani, with a novel robotic microscope, the RoboticScope, for the performance of microvascular anastomoses in a two-center preclinical trial.

Outcomes

Primary Outcomes

Anastomosis quality

Time Frame: Evaluated right after completion of each anastomosis

Anastomosis lapse index (ALI) to evaluate the quality of each stitch. Score indicates absolute number of errors per anastomosis. Low values indicate better results.

Microsurgical skills

Time Frame: Duration of anastomosis

Structured assessment of microsurgery skills (SAMS) to evaluate microsurgical skill acquisition. Score includes 8 items evaluated from 1 (minimum) to 5 (maximum). High values indicate better results.

Surgical time

Time Frame: Duration of anastomosis

Time to perform anastomosis in minutes and seconds.

Secondary Outcomes

  • Subjective Satisfaction(Evaluated right after completion of each anastomosis)
  • Surgical ergonomics(Evaluated right after completion of each anastomosis)
