Pelvic Implant with Bone-Fixed Base for Stable Width Augmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for enhancing waist-to-hip ratios through cosmetic surgery, such as liposuction and autologous fat transplantation, face limitations due to internal organ sizes and soft tissue instability, leading to difficulties in achieving desired proportions and maintaining implant stability.
Innovation Solution
A bio-compatible implant is designed to be fixed to the iliac crest of the pelvis using bone fasteners, with a contact surface matching the iliac crest's shape and an outer surface extending beyond its lateral region, providing stable fixation and increased apparent pelvic width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If autologous fat or silicon implant is transplanted onto soft tissue to increase lateral width of thigh or pelvis, then the lateral width is increased, but the implant becomes deformed or displaced due to stressful forces on soft tissues
Solution Approach 1:
The implant system is divided into two distinct components: a rigid base portion that is fixed to the iliac crest bone, and a separate outer surface portion that provides the cosmetic enhancement. This segmentation allows the stable fixation function to be separated from the volume enhancement function, resolving the contradiction between increasing lateral width and maintaining implant stability.
Solution Approach 2:
The invention transitions from soft tissue-based augmentation (superficial dimension) to bone-based augmentation (deep structural dimension). By anchoring the implant to the iliac crest bone rather than relying on soft tissue fixation, the system achieves stable fixation in the deep structural dimension while still achieving the desired lateral width increase in the superficial dimension.
2Area of stationary object
If chemical agents or liposuction are performed to reduce lateral width of waist to achieve desired waist-to-hip ratio, then the waist width is reduced, but the procedure is limited by basic sizes of internal organs and skeleton
Solution Approach 1:
Instead of reducing the waist width to achieve the desired waist-to-hip ratio (subtraction approach), the invention inverts the approach by increasing the hip/pelvis width through implantation (addition approach). This allows for greater adaptability in achieving target proportions without being constrained by the fixed sizes of internal organs and skeleton that limit waist reduction.
3Shape
If tight clothing and shearing force during ambulation are applied to soft tissue implant, then the implant is eventually deformed or displaced
Solution Approach 1:
The base portion of the implant is pre-configured with a contact surface that matches the curvature of the iliac crest, and is permanently fixed to the bone before the patient undergoes activities such as ambulation or wears tight clothing. This preliminary fixation to the rigid bone structure prevents the implant from being deformed or displaced by subsequent shearing forces that would otherwise affect soft tissue implants.
