Hip Distraction Boot With Vacuum Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hip distraction systems during arthroscopic hip surgical procedures face challenges in securely holding the leg in place, leading to potential slippage and collapse of the hip joint opening.
Innovation Solution
A surgical boot system with an L-shaped rigid shell, a soft liner, and strap assemblies, combined with a sleeve accessory featuring a braided construction and vacuum port, to provide secure and stable leg positioning during hip distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid shell boot is used to hold the leg during hip distraction, then the leg positioning stability is improved, but the leg and foot may still slip and migrate proximally causing the hip joint opening to collapse
Solution Approach 1:
The boot is divided into multiple functional segments: a rigid shell for structural stability, a flexible distal portion for adaptive fitting, and multiple strap assemblies for distributed securing. This segmentation allows each part to perform its specific function optimally while working together to prevent slippage.
Solution Approach 2:
The boot incorporates dynamic elements including a flexible distal portion that can adapt to foot shape changes, adjustable strap assemblies that can be tightened or loosened, and a pivotable rigid shell that allows controlled movement. These dynamic features enable the boot to maintain secure positioning while accommodating natural leg movements.
2Reliability
If straps and pads are used to secure the leg in the boot, then the leg holding capability is improved, but the complexity of the securing mechanism increases
Solution Approach 1:
Multiple securing functions are merged into integrated strap assemblies that combine straps, pads, and adjustment mechanisms into single unified components. This merging reduces the number of separate parts and simplifies the overall securing mechanism while maintaining reliable leg holding capability.
Solution Approach 2:
The strap assemblies are designed as multi-functional components that provide multiple functions: securing the leg, distributing pressure through pads, and allowing adjustment. This universality reduces complexity by eliminating the need for separate components for each function.

AI summary
A surgical boot system and sleeve accessory for hip distraction. The surgical boot system includes an L-shaped rigid shell having a proximal portion and a distal portion. A soft liner is attached to the rigid shell and extends along at least one of the proximal portion and the distal portion. The surgical boot system also includes at least one strap assembly (which can be a plurality of strap assemblies) extending around the rigid shell. A load transmission hoop is connected to and extends around the distal portion of the rigid shell and an attachment point is connected to the load transmission hoop. The rigid shell is pivotable about the attachment point. Specifically, the attachment point is configured to interface with a hip distractor apparatus in a way that allows for multiple degrees of freedom.
