Integrated Catheter Guide Wire Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgery systems face challenges in precision due to the difficulty in coordinating the motion of robotic catheters and guide wires, requiring operators to use separate controls for each, which can lead to imprecise control during procedures.
Innovation Solution
A device that allows single-digit operation of a guide wire for both axial movement and rotation, enabling simultaneous control of the guide wire's insertion and rotation, allowing the other hand to control the catheter, using various control mechanisms such as pivotable, slidable, and rotary devices integrated with a joystick or trackball for precise manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate controls are used for catheter and guide wire, then each component can be controlled independently, but coordination precision between catheter and guide wire deteriorates
Solution Approach 1:
The patent combines separate catheter control and guide wire control into a single integrated controller unit. The controller housing contains both the catheter manipulation controls (joystick, buttons) and guide wire controls (knobs, buttons) in one unified device, allowing the operator to control both components from a single location, thereby improving coordination precision while maintaining independent control capability.
2Adaptability or versatility
If multiple separate controls are used for guide wire manipulation, then control functions are comprehensive, but operator complexity increases
Solution Approach 1:
The integrated controller serves multiple functions within a single device: it controls both catheter manipulation (via joystick and buttons) and guide wire manipulation (via knobs and buttons). This multi-functional design consolidates what would otherwise require separate control devices, reducing overall system complexity while maintaining comprehensive control capabilities.
3Ease of operation
If both hands are used for controlling catheter and guide wire separately, then control coverage is maximized, but operational efficiency for coordinated motions deteriorates
Solution Approach 1:
The patent merges catheter and guide wire controls into one controller that can be operated with both hands simultaneously. The left hand can operate the joystick for catheter control while the right hand operates the knobs for guide wire control, both on the same controller unit. This unified design enables efficient coordinated motions by allowing both hands to work together on a single device, improving operational efficiency compared to using separate controllers.

AI summary
A device may operate a guide wire and be operable by a single operator digit. The device may include an insertion control device for advancing the guide wire in a forward and in a reverse direction and along a longitudinal axis of the guide wire; and a rotary device for rolling a guide wire about the longitudinal axis. A robotic instrument driver may be operatively coupled to the device and configured to control axial movement of the guide wire along the longitudinal axis according to input received from the insertion control device and to control rotational movement of the guide wire according to input received from the rotary device.
