Solution Overview

Problem

Existing robotic surgical systems, particularly for endoluminal and single-site surgery, lack improvements in controller configurations and components that enhance maneuverability and efficiency, limiting their effectiveness in minimally invasive procedures.

Innovation Solution

A controller system comprising a camera controller with three degrees-of-freedom (DOF) motors and pushing actuators, positioned symmetrically between two instrument controllers, allows for enhanced steering and axial translation of a robotically controlled endoscopic camera, along with instrument controllers to steer attachable medical devices, facilitated by a non-transitory computer-readable medium for motor control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional robotic surgical controllers are used, then basic surgical control is provided, but maneuverability and control precision of robotic instruments are limited

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidcontroller configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The controller system is divided into separate functional modules: a first instrument controller for controlling first robotic instruments, a second instrument controller for controlling second robotic instruments, and a camera controller for controlling the endoscopic camera. Each controller independently manages its specific instruments, allowing optimized control of each degree of freedom while maintaining overall system coordination through the base station.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If multiple incisions are made to access surgical locations, then instrument access is improved, but patient trauma and recovery time increase

Engineering Contradiction:
Improveinstrument accessVSAvoidpatient trauma
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The robotic instruments are designed to be inserted through a single small incision site, with the instruments nested within each other during insertion. The first and second robotic instruments can be sequentially inserted through the same access site, allowing multiple instruments to share a single entry point into the patient's body, thereby minimizing trauma while maintaining surgical accessibility.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If traditional robotic surgery approaches are used, then surgical procedures can be performed, but procedural efficiency and safety are reduced

Engineering Contradiction:
Improveprocedural efficiencyVSAvoidprocedural safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The base station receives real-time position and orientation data from both robotic instruments and the endoscopic camera, enabling continuous feedback control. The system can detect instrument positions, calculate spatial relationships, and provide real-time guidance to maintain proper instrument orientation and prevent collisions, thereby enhancing both efficiency and safety during minimally invasive procedures.

Inventive Principle:
Principle #23Feedback
