Project Summary

More and more patients are adopting minimally invasive surgery (MIS), because this technique allows surgeons to insert thin instruments and an endoscope into patient’s body through small incision. One of the advance state of MIS is robot assisted surgery that allows the surgeon, to conduct minimally invasive surgery with increased accuracy and has potential benefits for patients. It provide extra degrees of freedom and high precision compared to a human hand. Patients experience less pain, smaller trauma, and recover more quickly. That is why it is taking over the traditional open surgery which lacks such capabilities. Our project will design and develop a prototype for surgical robot, which will be able to perform a basic function involved in every surgery i.e. suturing. The mechanical design of the system will consist of two workstations the main console and robotic manipulators. Main console will be a workstation from where the surgeon will control the robotic arms and surgical tools. It will comprise of joystick as an input device and a display screen with a camera at the other end for visualization. Whereas, robotic manipulators will comprise of two independent robotic arm frames, equipped with Maryland Laparoscopic graspers suitable for suturing. Each robotic arm, will receive commands from the main console to actuate the servo motors and Maryland laparoscopic grasper. This will be a two- way communication pathway allowing a controlled response. Servo motors will drive each active joint and imitate the movement signals send by the main console. Microcontroller will control each of the robotic arm, which is an integral part of the system that links the input signal provided by the joystick to the robotic arms for the actuation of the suturing task. The final prototype will be able to perform suturing which is a basic function involve in every surgical procedure.

Project Objectives

• We aim to design and develop a prototype of surgical robot, equipped with laparoscopic grasper ideal for basic surgical procedures such as suturing.
• To design a control system algorithm, based on required performance criteria.
• Designing of a customized joystick according to the control requirement of the surgical task
• Integration of software and hardware systems for acquiring the goal of the project i.e. suturing.

Project Implementation Method

• Detailed literature review to gain knowledge about the project details prior to its implementation.
• Practicing of suturing to have a better understanding of the procedure and degree of freedom required for its operation by the robot.
• Designing of mechanical body of 5 degree of freedom (DOF) robotic manipulators.
• Purchase of required equipment.
• Hardware system development, which includes the main console and the robotic manipulators.
• Designing and implementation  of control system algorithm for servomotors.
• Implementation of endoscopic camera for visual information
• Integration of hardware and software systems (final prototype).
• Testing of final prototype.
• Result formulation.
• Compilation and final write-up.

Benefits of the Project

Robotic Surgery is one of the latest technology, the surgeons and patients are opting for as both of them get benefit from these type of surgeries.

A surgical robot aids a surgeon with enhanced precision, flexibility, control and vision, while patients experience less pain, smaller trauma, and recover more quickly than a conventional open surgery. But these type of Robotic systems used for minimal invasive surgeries are complex and expensive and are not readily available in many under developing countries including Pakistan.

According to literature, only lesser amount of work has been reported in the development of surgical robots in Pakistan and our project focus in this area and develops a robot that can lead to the development of complex robotic systems. 

That is why our surgical robot is a much simpler and inexpensive prototype that for the start will be able to perform one of the basic surgical procedure i.e. suturing.

Our design is flexible towards modification and can even lead to the advance developments such as telemetric robotic operation.

Technical Details of Final Deliverable

The final prototype of the project will consist of surgical robot with its control system. It will have the capability to perform suturing which is a basic function involved in every surgical procedure. An input device (Joystick) will operate the surgical robot. Using this input device, robotic arms equipped with Maryland laparoscopic grasper can be moved in desire direction. This system will be controlled by a main controller that links the input signal provided by the main console to the robotic manipulators for the actuation of suturing task. An endoscopic camera will provide visual information about the suturing site, and is responsible for the operation of the task. . Our robotic system  will be user friendly and convenient to use .
