Sterile Master Handle Rest for Switching Robotic Surgery Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a solution that allows surgeons to effectively alternate between robot-aided and traditional surgery within a single intervention, while maintaining sterility in the sterile operatory field, and simplifying the switching process between the two modes.
Innovation Solution
A master workstation comprising a mechanically ungrounded master input handle and a sterile drape with integrated sterile holders that provide a cavity for resting the handle when not in use, allowing easy access and maintaining sterility within the sterile operatory field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the surgeon uses a remote master console located outside the sterile operatory field, then the surgeon's comfort and ergonomics are improved, but communication problems arise between the surgeon and the surgical team
Solution Approach 1:
The master console is made dynamically positionable within the sterile field through a mobile cart design, allowing the surgeon to adjust the console location to optimize both ergonomic comfort and communication with the surgical team while maintaining sterility through removable drape coverage
2Loss of information
If the surgeon attends the sterile operatory field to improve communication, then communication effectiveness is improved, but the surgeon cannot maintain ergonomic comfort and may contaminate the sterile field
Solution Approach 1:
The mobile cart design enables the surgeon to dynamically position the master console at optimal locations within the sterile field, balancing communication needs with ergonomic requirements while maintaining sterility through removable drape coverage
3Reliability
If the master input handle is placed outside the sterile field, then sterility is maintained, but the surgeon cannot easily access it during surgery
Solution Approach 1:
The system is segmented into sterile and non-sterile zones using removable drape coverage on the mobile cart, allowing the master input handle to be positioned within the sterile field for easy access while maintaining sterility through the drape barrier that can be selectively removed or adjusted
4Ease of operation
If the master input handle is placed within the sterile field for easy access, then accessibility is improved, but sterility may be compromised
Solution Approach 1:
The mobile cart is divided into sterile and non-sterile sections using removable drape coverage, allowing the master input handle to reside in the sterile zone for easy access while the drape maintains the sterility barrier when needed
Solution Approach 2:
The removable drape coverage provides dynamic sterility control, allowing the surgeon to adjust or remove the drape temporarily for handle access while maintaining sterility during critical surgical phases
5Shape
If the surgical drape volume is reduced for better fit, then drape tightness is improved, but the drape may break more easily
Solution Approach 1:
The drape system is segmented with strategic reinforcement zones at high-stress areas while maintaining reduced volume in non-critical areas, achieving both tight fit and durability through differentiated material distribution
Solution Approach 2:
The surgical drape utilizes composite material construction combining different fabric layers with varying properties, where reinforcement layers are strategically placed to strengthen high-stress areas while maintaining overall drape flexibility and fit
