Asymmetrical Anoscope Wings Tissue Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anoscope designs lack sufficient maneuverability, making it difficult for clinicians to access and treat internal tissue sites, particularly during hemorrhoid procedures, as they do not provide adequate structural features for easy manipulation and tissue engagement.
Innovation Solution
The insertion device includes an anoscope with a flange and an elongate body that is either asymmetrical or symmetrical about a longitudinal axis, featuring wings and a lip for enhanced maneuverability, along with a port that has wings for secure tissue attachment, facilitating easier access and manipulation during surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional symmetrical anoscope design is used, then manufacturing is simple, but maneuverability and tissue access capability are insufficient
Solution Approach 1:
The anoscope is designed with an asymmetrical configuration where the distal opening is offset from the longitudinal centerline of the body, creating unequal sides that allow the gap to engage tissue more effectively. This asymmetry provides improved maneuverability and tissue access capability while maintaining a relatively simple overall structure.
2Ease of operation
If traditional anoscope design without wings is used, then structure is simpler, but manipulation and tissue engagement are difficult
Solution Approach 1:
The anoscope incorporates wings as separate structural elements that extend from the body. These wings can be positioned at different locations and orientations, providing additional manipulation points for the clinician while maintaining a modular structure that does not significantly increase overall complexity.
Solution Approach 2:
Wings are added as protruding elements that extend laterally from the main body of the anoscope, creating a three-dimensional structure. This adds manipulation surfaces in a different dimensional plane, improving ease of grasp and orientation without complicating the primary longitudinal structure.
3Reliability
If traditional anoscope without flange features is used, then insertion is simpler, but secure positioning and attachment are difficult
Solution Approach 1:
The flange is designed with a gap that is pre-configured to engage with tissue or surgical fasteners before the main surgical action takes place. This preliminary engagement provides stable positioning and secure attachment, allowing subsequent surgical procedures to be performed with confidence in the device's stability.
Solution Approach 2:
The flange acts as an intermediary structure between the anoscope body and the tissue/fastener system. It provides a dedicated interface for engagement, mediating the connection between the device and the biological tissue, thereby improving positioning stability without requiring complex anchoring mechanisms.

AI summary
An insertion device for use during surgical procedure to enlarge an opening in a patient's tissue to facilitate access to an internal treatment site with a surgical instrument. The insertion device includes an anoscope including a flange, and an elongate body having proximal and distal ends extending distally from the flange along a longitudinal axis. The anoscope may include a configuration that is asymmetrical about a plane extending along the longitudinal axis that bisects the flange.
