Solution Overview

Problem

Robotic surgical systems face inefficiencies during procedures due to the need for surgeons to remove their hands from tool controls to adjust the image capturing device's viewpoint, causing discontinuities and delays.

Innovation Solution

A hand-based controller with an attachment member and interface allows clinicians to redirect the image capturing device's viewpoint without removing their hands from tool controls, using a joystick or touch-sensitive surface for pan, rotation, and zoom functions, potentially integrated into a glove or attached to the hand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the surgeon removes their hand from tool controls to adjust the image capturing device, then the viewpoint can be adjusted, but the procedure experiences discontinuity and delay

Engineering Contradiction:
Improveviewpoint adjustment capabilityVSAvoidprocedure continuity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent combines the control of the image capturing device with the surgical tool control by integrating a controller into the tool handle. This allows the surgeon to adjust the viewpoint while maintaining hand placement on the tool controls, eliminating the need to remove hands from controls and thus preventing procedure discontinuity and delay.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller acts as an intermediary device that enables viewpoint adjustment without requiring direct manual manipulation of the image capturing device. By incorporating control mechanisms (such as buttons, switches, or joysticks) into the tool handle, the system mediates between the surgeon's hand position and the image capturing device control, allowing simultaneous operation of both tools and imaging functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the surgeon requests an assistant to manipulate the image capturing device, then the viewpoint can be adjusted, but the procedure experiences delay

Engineering Contradiction:
Improveviewpoint adjustment capabilityVSAvoidprocedure delay
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables self-service by equipping the surgical tool handle with integrated controls that allow the surgeon to independently adjust the viewpoint without requiring assistance from an assistant. The controller provides autonomous control capability directly to the surgeon, eliminating the need for assistant intervention and associated delays.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If a separate controller is used for the image capturing device, then control precision can be maintained, but the device complexity increases

Engineering Contradiction:
Improvecontrol precisionVSAvoidcontroller integration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Instead of using a completely separate controller, the patent merges the control functions into the tool handle assembly. This integration maintains control precision for the image capturing device while reducing overall system complexity by eliminating the need for additional standalone controllers and their associated wiring and spatial arrangements.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A controller includes an attachment member and an interface. The attachment member is configured to secure the controller to a hand of a clinician. The interface includes a first controller that is configured to operate an imaging device of a surgical system. The controller can secure about a finger of a clinician and be engagable by a thumb of the same hand of the clinician. Alternatively, the controller can be disposed in a palm of a hand of a clinician and engaged by a finger of the hand.
