Use of a Minimally Invasive Robot for Laparoscopic Surgery: Design and Development
Background:
With the application of artificial intelligence and sensor technology in the medical field, medical services have become truly intelligent. In the context of China's new medical reform, Wise Information Technology of 120 has gradually entered the lives of ordinary people. However, the quality and efficiency of robot-assisted surgical treatment for intelligent minimally invasive laparoscopic surgery remain to be improved.
Objective:
This study aimed to assess the application effect of a microinvasive laparoscopic robot in retroperitoneal laparoscopic ureterolithotomy (RLU) and to compare the effect of minimally invasive robotic surgery and minimally invasive surgery by a doctor on postoperative rehabilitation nursing.
Methods:
Comparison of a three-degree of freedom minimally invasive surgical robot was performed. On this basis, a six-dimensional torque sensor was used at the end of the machine. Thereafter, the effect of the machine was tested in a no-load experiment. At the same time, robot-assisted and traditional minimally invasive methods were used for RLU. Finally, under the accelerated rehabilitation nursing mode, the rehabilitation effect of patients was compared.
Results:
The accuracies of roll, yaw, pitch, and open and close of the minimally invasive laparoscopic surgery robot were 0.27 mm, 0.26 mm, 0.28 mm, and 0.52 mm, respectively, and the accuracies of the repeat positioning angle were 2.5°, 3.1°, 3.8°, and 2.9°, respectively. The execution error of the six-dimensional force/torque sensor was less than 5%, which was acceptable. The six-dimensional force/torque sensor on the robotic surgical end effector transmitted touch signals in real time for precise blunt separation. When applied to the adjuvant therapy of ureteroscopic lithotomy, there were no relevant differences in postoperative vital signs and the probability of perioperative complications between it and ureteroscopic lithotomy, and the postoperative complication rate was 0%.
Conclusions:
The minimally invasive laparoscopic surgery robot proposed in this study has good surgical performance and lays the foundation for promoting the intellectualization of medical services.
