Percuscopic Access Device With Barrier Ridges And Cleaning Obturator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During minimally invasive surgical procedures, bodily fluids often foul the lens of viewing scopes inserted through cannulas, leading to the need for effective devices that reduce fluid contact and facilitate easy cleaning to maintain clear visuals.
Innovation Solution
A percuscopic access device with barrier ridges and recesses to minimize fluid contact, combined with a cleaning obturator featuring a guide rod and swab guides for effective cleaning, reduces the likelihood of fluid fouling and allows for easy maintenance of the viewing scope's lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a viewing scope is inserted through a cannula for percuscopic access, then surgical visualization is enabled, but bodily fluids foul the lens of the viewing scope
Solution Approach 1:
A cleaning obturator is introduced as an intermediary device between the cannula and the viewing scope. The obturator includes a plugging tip that seals the distal end of the cannula and a guide rod with swab guides that allow cleaning swabs to be passed through, creating a protective barrier system that prevents fluid fouling while enabling scope insertion and cleaning
Solution Approach 2:
The cleaning obturator is inserted into the cannula before the viewing scope is introduced. This preliminary action establishes a protective configuration where the obturator's plugging tip seals the distal end and the swab guides are positioned to receive cleaning swabs, preventing fluid fouling before it can occur during the surgical procedure
2Ease of operation
If the cannula distal end is open to allow scope insertion, then percuscopic access is enabled, but fluids can contact and foul the viewing scope lens
Solution Approach 1:
The cleaning obturator serves as a mediator device that remains in place within the cannula, allowing the viewing scope to pass through its guide rod while the plugging tip seals the distal end. This intermediary structure enables scope insertion while preventing fluid access to the scope lens
Solution Approach 2:
The cleaning obturator is nested within the cannula, with the guide rod containing the swab guides. This nested configuration allows the viewing scope to be inserted through the obturator's guide rod while the obturator itself remains protected within the cannula, creating multiple layers of protection and access pathways
3Reliability
If frequent lens cleaning is performed to maintain visualization, then lens clarity is maintained, but surgical procedure time increases
Solution Approach 1:
The cleaning obturator is prepared and inserted into the cannula before the viewing scope is introduced and before any fluid fouling can occur. This preliminary configuration of the cleaning system eliminates the need for frequent interruptive cleaning operations during the surgical procedure
Solution Approach 2:
The cleaning obturator with its swab guides is designed to allow the surgical team to perform quick cleaning operations independently without requiring scope removal or complex cleaning procedures. The swabs can be easily inserted through the guides to clean the lens while the scope remains in place, enabling rapid self-service cleaning that minimizes procedure interruption
