Multi-Level Levatorplasty Anchorage for Rectocele Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical methods for treating vaginal prolapse, particularly rectocele, face high failure rates and complications such as levator muscle ballooning and mesh erosion, necessitating improved anchorage techniques to enhance the longevity and effectiveness of levatorplasty repairs.
Innovation Solution
A multi-level, tension-free levatorplasty method that anchors or pins the rectocele posteriorly using implants at two anatomical levels, providing additional support to the levator musculature with synthetic or biological materials, thereby minimizing ballooning and stress-related failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional single-level levatorplasty is performed, then the surgical procedure is simple, but the repair fails frequently due to levator muscle ballooning and insufficient anchorage
Solution Approach 1:
The levatorplasty procedure is divided into multiple levels (at least two distinct anatomical levels) with separate anchorage points. Each level provides independent support, preventing the levator muscle from ballooning between single anchorage points. This segmentation transforms a single-point failure system into a multi-point distributed support system, significantly improving repair reliability.
Solution Approach 2:
The invention transitions from traditional single-plane anchorage to multi-level three-dimensional anchorage. By placing anchors at different vertical levels within the levator muscle complex, the repair creates a distributed support architecture that resists ballooning forces more effectively, enhancing durability without excessive complexity.
2Reliability
If traditional levatorplasty without posterior anchoring is used, then the surgery is less complex, but levator muscle ballooning occurs frequently leading to repair failure
Solution Approach 1:
The posterior anchoring is performed prophylactically to prevent levator muscle ballooning before it can occur. By securing the posterior aspect of the levator complex at multiple levels, the invention creates preemptive counterforces that resist the ballooning tendency during stress events, thereby preventing repair failure rather than correcting it afterward.
3Strength
If mesh is used for reinforcement, then structural support is improved, but mesh erosion complications increase
Solution Approach 1:
The invention removes mesh from the surgical technique entirely, relying instead on sutures and anchors placed at multiple levels within the levator muscle. This extraction of the problematic mesh component eliminates the source of erosion complications while maintaining structural support through the multi-level anchorage system that distributes forces across healthy tissue.
4Duration of action of stationary object
If multi-level tension-free levatorplasty with posterior anchoring is performed, then repair durability and resistance to ballooning are significantly improved, but the surgical procedure becomes more complex
Solution Approach 1:
The multi-level anchors are placed and secured before the final reconstruction steps are completed. By establishing the anchorage framework first, the surgeon creates a pre-positioned support structure that guides subsequent tissue repositioning and closure, making the increased complexity more manageable and systematic rather than chaotic.
