Solution Overview

Problem

Existing surgical robotic systems face challenges with spatial constraints and mechanical features due to the addition of multiple functional components, which complicates the actuation structures, deployable components, and electrical connections required.

Innovation Solution

A surgical system that includes a surgical instrument with movable jaw members for grasping tissue and a probe that can connect to a source of energy, movable from a retracted to a deployed position. The system also features a camera, controller, and monitor for capturing and displaying video of the tissue and surgical instrument, along with a virtual representation of the probe, to assist in precise tissue treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional functional components are added to surgical instruments, then the treatment capability and versatility are improved, but the spatial constraints and mechanical complexity worsen

Engineering Contradiction:
Improvetreatment capabilityVSAvoidmechanical complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components (jaw members for grasping, probe for energy delivery, camera for visualization) into a single integrated surgical instrument. This merging approach allows the instrument to perform multiple functions (tissue grasping, energy delivery, visualization) while reducing the overall number of separate devices needed, thereby improving versatility without proportionally increasing mechanical complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The surgical instrument is designed as a universal platform that can perform multiple surgical functions through different components. The jaw members can grasp and treat tissue, the probe can deliver energy, and the camera can capture images - all within a single instrument. This multi-functionality improves adaptability while sharing common structural and control systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If additional functional components are added to surgical instruments, then the treatment capability is improved, but the spatial constraints worsen

Engineering Contradiction:
Improvetreatment capabilityVSAvoidspatial constraints
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The probe is positioned within or alongside the jaw members in a nested arrangement, allowing the probe to be housed within the overall instrument structure when not in use. This nesting approach minimizes the spatial footprint of the instrument while still accommodating all functional components (jaw members, probe, camera) within a compact form factor

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The instrument components are arranged in three-dimensional space to optimize spatial utilization. The probe can extend from the jaw members in a direction that does not increase the lateral footprint, and the camera is positioned to capture images without adding significant bulk. This dimensional arrangement allows multiple functions within constrained spatial boundaries

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If additional functional components are added to surgical instruments, then the treatment capability is improved, but the actuation structures required worsen

Engineering Contradiction:
Improvetreatment capabilityVSAvoidactuation structures
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The surgical instrument uses a universal actuation system that can control multiple functions through shared control mechanisms. The robotic arm provides standardized actuation inputs that can operate the jaw members for grasping, deploy the probe for energy delivery, and control the camera for visualization. This universal actuation approach improves treatment capability while avoiding proportional increases in actuation structure complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
