Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing surgical robotic systems are complex, costly, bulky, and limit surgeon access to the patient, requiring additional sterilization procedures and are not well-suited for minimally invasive surgeries due to high inertia and limited dexterity.

Innovation Solution

A remotely actuated surgical robot system with robotic telemanipulators that are low-cost, integratable into the operating room, allow sterile surgeon access, and enable integrated laparoscopy, featuring a master console with removable handles and a slave console with adjustable links and actuators for precise instrument control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional laparoscopic instrumentation is used, then minimally invasive surgery is achieved, but surgeon dexterity and precision are reduced due to the fulcrum effect and inverted movements

Engineering Contradiction:

Improveminimally invasive natureVSAvoidsurgeon dexterity

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The robotic system inverts the traditional laparoscopic approach by placing the console near the patient rather than far away. This allows the surgeon to stand close to the patient, eliminating the fulcrum effect and inverted movements while maintaining minimally invasive access through small incisions.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

A robotic arm acts as an intermediary between the surgeon and the surgical instruments. The robotic arm transmits the surgeon's hand movements directly to the instrument tips without the fulcrum effect, preserving dexterity and precision while enabling minimally invasive surgery through small incisions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If robotic surgical systems are used, then surgeon ergonomics and precision are improved, but system complexity, cost, and bulkiness increase

Engineering Contradiction:

Improvesurgeon ergonomicsVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts only the essential robotic components needed to eliminate the fulcrum effect - specifically a robotic arm with a console positioned near the patient. This simplified approach removes unnecessary complexity while retaining the key benefits of improved ergonomics and precision.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The robotic system is designed to perform multiple surgical functions through a single integrated platform. The robotic arm can accommodate various surgical instruments and the console can be repositioned for different surgical approaches, reducing the need for multiple specialized systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If robotic arms are positioned far from the patient, then surgeon access is improved, but sterility maintenance becomes difficult requiring additional procedures

Engineering Contradiction:

Improvesurgeon accessVSAvoidsterility maintenance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The robotic arm serves as a sterile intermediary that can be positioned close to the patient while the surgeon remains at a controlled distance. The robotic arm maintains sterility through its design and can be easily sterilized, eliminating the need for additional sterilization procedures while allowing surgeon access.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If long and straight instruments are used in laparoscopy, then minimally invasive access is achieved, but surgeon posture becomes uncomfortable and tiring

Engineering Contradiction:

Improveminimally invasive accessVSAvoidsurgeon posture

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system inverts the traditional setup by positioning the console near the patient rather than far away. This allows the surgeon to stand in a comfortable, natural posture while performing minimally invasive surgery, eliminating the need to work in uncomfortable positions with long straight instruments.

Inventive Principle:

Principle #13The other way round (Inversion)

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 integratable 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.
