Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion devices face difficulties in maneuvering around internal obstructions, such as the pubic bone, during surgical procedures, leading to tissue trauma and inefficiency in delivering mesh carriers to inaccessible locations within the body.
Innovation Solution
An insertion device with an elongate member and stylet configuration, featuring a curved portion and orthogonal axis arrangement, allows for precise placement and removal of mesh carriers around obstructions, minimizing tissue trauma and improving accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a known insertion device is used to position a mesh carrier at a difficult-to-reach location, then the mesh carrier can be delivered to the target site, but the device requires a larger incision and causes tissue stretching or tearing due to rotation and pivoting maneuvers
Solution Approach 1:
The insertion device incorporates a curved portion in its elongate member that allows the device to navigate around the pubic bone and other internal obstructions without requiring rotation or pivoting maneuvers. The curved geometry enables the distal end to reach difficult-to-access locations while the proximal end remains accessible for mesh carrier deployment, eliminating tissue stretching and tearing caused by rotational movements.
Solution Approach 2:
The insertion device is divided into distinct functional segments: a proximal end portion with a handle for operator control, a curved portion for navigation around obstructions, and a distal end portion for mesh carrier delivery. This segmentation allows each portion to perform its specific function optimally while working together as an integrated system, reducing the need for traumatic maneuvers.
2Adaptability or versatility
If a known insertion device is maneuvered around internal obstructions such as the pubic bone, then the mesh carrier can be delivered to inaccessible locations, but the device requires excessive rotation and pivoting that induces tissue trauma
Solution Approach 1:
The curved portion of the elongate member is specifically designed to conform to the anatomical contours around the pubic bone and other internal obstructions. This pre-configured curvature allows the device to follow the natural pathways of the body, reaching inaccessible locations without requiring the operator to rotate or pivot the device, thereby avoiding tissue trauma while maintaining high adaptability.
3Ease of operation
If a larger incision is made to allow rotation and pivoting of the insertion device, then the mesh carrier can be positioned at difficult locations, but the incision size increases and tissue trauma increases
Solution Approach 1:
The curved portion enables the device to achieve excellent maneuverability around internal obstructions while maintaining a small incision size. The curved geometry acts as a built-in navigation mechanism that guides the distal end around the pubic bone and other structures, eliminating the need for large incisions that would be required to accommodate rotational maneuvers.
4Manufacturing precision
If the insertion device is removed and reinserted to better position it at the incision site, then positioning accuracy may improve, but the procedure time increases and additional tissue trauma occurs
Solution Approach 1:
The curved portion is designed to provide optimal positioning capability in a single insertion. The curved geometry pre-positions the distal end at the correct angle and location relative to the pubic bone and target site, eliminating the need for removal and reinsertion. This maintains high placement precision while significantly reducing procedure time and avoiding additional tissue trauma from repeated insertions.

AI summary
An insertion device includes an elongate member and a stylet. The elongate member has a proximal end portion, a distal end portion, and defines a lumen therethrough. The stylet has a proximal end portion, a distal end portion, and is slidably coupled to the elongate member. The stylet is configured to move from a first position to a second position with respect to the elongate member. The proximal end portion of the stylet is configured to removably couple a mesh carrier thereto. A portion of the proximal end portion of the stylet is disposed outside of the lumen of the elongate member when the stylet is in its first position and is disposed within the lumen when the stylet is in its second position.
