Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional robotic surgical systems are used, then surgical precision and dexterity are improved, but system complexity and cost increase significantly

Engineering Contradiction:

Improvesurgical precisionVSAvoidsystem complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The surgical robot system is divided into separate functional modules: a master console for surgeon control, a slave console for instrument manipulation, and removable handles for sterilization. This segmentation allows each component to be optimized independently while reducing overall system complexity and cost.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handles are extracted as removable components from the master console, allowing them to be sterilized separately and reused across multiple procedures. This extraction reduces the permanent complexity of the main system while maintaining surgical precision capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

2Manufacturing precision

If traditional robotic surgical systems are used, then surgical precision is improved, but affordability decreases

Engineering Contradiction:

Improvesurgical precisionVSAvoidaffordability

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The handles are designed as disposable or easily sterilizable components rather than permanent expensive parts. This allows the main robotic system to be more affordable while maintaining surgical precision through the use of cost-effective, replaceable interface components.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Manufacturing precision

If bulky robotic systems are used, then surgical precision is improved, but space availability in operating room decreases

Engineering Contradiction:

Improvesurgical precisionVSAvoidspace availability

Core Design Contradiction:

Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The system is segmented into compact modular units (master console, slave console, handles) that can be positioned strategically in the operating room. This segmentation reduces the footprint of each component while maintaining overall surgical precision capabilities.

Inventive Principle:

Principle #1Segmentation

4Device complexity

If non-sterile robotic systems are used, then system complexity is reduced, but surgical safety decreases

Engineering Contradiction:

Improvesystem complexityVSAvoidsurgical safety

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The handles are extracted as separate sterilizable components that interface between the sterile surgical field and the non-sterile robotic system. This allows the main system to remain simpler and less expensive while ensuring surgical safety through dedicated sterilizable interfaces.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The removable handles act as intermediaries between the non-sterile robotic control system and the sterile surgical environment. These handles can be sterilized and disposed of or reused, maintaining surgical safety without requiring the entire robotic system to be sterile or overly complex.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Surgical robot systems for remote manipulation having robotic telemanipulators are provided. The surgical robot systems are well adapted for use by the surgeon, seamlessly integrateable into the operation room, allow for a surgeon to work between the robot and the patient throughout a surgery in a sterile manner, are relatively low cost, and/or permit integrated laparoscopy. The system preferably includes a master console having a plurality of master links interconnected by a plurality of master joints, and a handle coupled to the master console for operating the telemanipulator. The system further includes a slave console operatively coupled to the master console and having a plurality of slave links interconnected by a plurality of slave joints that move responsive to movement at the master console to permit an end-effector to perform surgery.
