This study introduces PARAMIS, a low-cost surgical robot for precise laparoscopic camera positioning. Its intuitive controls and tremor-filtering capabilities enhance surgical procedures and reduce surgeon fatigue.

Area of Science:

Robotics
Minimally Invasive Surgery
Surgical Technology

Background:

Laparoscopic surgery requires precise instrument and camera control.
Existing systems may be costly or lack advanced features.
The development of cost-effective, high-precision robotic systems is an ongoing need.

Purpose of the Study:

To present the development and initial evaluation of the PARAMIS surgical robot.
To demonstrate its capability for precise laparoscopic camera positioning.
To assess its potential for improving surgical procedures.

Main Methods:

Mathematical modeling and development of a low-cost experimental parallel robot (PARAMIS).
Implementation of versatile control interfaces including joystick, microphone, keyboard/mouse, and haptic device.
