MU-LapaRobot: A Corporative Surgical Robot for Laparoscopic Surgery

The Open Biomedical Engineering Journal 26 Oct 2020 RESEARCH ARTICLE DOI: 10.2174/1874120702014010043

Abstract

Objective:

Development of surgical instrument robot (MU-LapaRobot) for assisting in conventional laparoscopic surgery.

Methods:

A robot was designed based on instrument movement for a conventional procedure. The mechanism mimics and constrains manipulation movement through the wire-driven transmission. It is flexible for robot end-effector, which has a lightweight and small size. The usability of the robot is passive and active robot tasks with an interconnected driving system. Three main parts of the robot are robot end-effector, transmission, and a driving system.

Results:

On a robot platform, a parameter for setup is robot posture. The adjustment of robot position and projection of manipulation area is influenced by the accuracy of movement. To verify movement, command and exact movements are measured. Compensation with the control system is improved in order to improve the accuracy of the system.

Conclusion:

MU-LapaRobot provides surgical instrument manipulation by using wire-driven transmission with an effective system and requires less interference in the conventional operation.
