Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical pin wound dressing methods lack symmetrical compression, create an open environment that allows bacterial contamination, and fail to adequately stabilize surgical pins, leading to skin breakdown, infections, and inefficient dressing changes, resulting in increased healthcare costs and waste.
Innovation Solution
A surgical pin compression wound dressing system comprising a stabilizing device with an upstanding body and a compressive wound dressing module that provides symmetrical compression, creates a closed environment, and includes a drainage port to isolate and manage wound drainage, ensuring precise geometric coupling and stabilization of surgical pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If collars, retainers or clips are used to stabilize wound dressing, then the wound dressing can be secured in place, but symmetrical wound compression is not achieved leading to asymmetric skin tension and possible skin breakdown
Solution Approach 1:
The device is divided into multiple independent components: a stabilizing device with compression members, a wound dressing module, and a drainage system. Each component performs a specific function, allowing precise control over compression symmetry while maintaining stabilization capability.
Solution Approach 2:
The invention intentionally uses asymmetric compression members that can be positioned at different locations and with different compression forces to achieve symmetrical overall compression. The non-circular compression members allow differential compression forces to be applied in specific directions to balance skin tension uniformly.
2Object-generated harmful factors
If open wound dressing is used, then drainage can occur, but bacteria can track from skin into surgical pin site causing infection
Solution Approach 1:
The drainage system is nested within the closed wound dressing environment. The drainage catheter is positioned inside the wound dressing module, allowing drainage to occur while remaining contained within the sterile barrier, preventing bacterial contamination of the surgical pin site.
Solution Approach 2:
A drainage catheter acts as an intermediary between the wound site and the external environment. It provides a controlled pathway for drainage while maintaining the closed sterile environment, preventing direct contact between bacteria and the surgical pin site.
3Ease of operation
If insufficient pressure is applied to stabilize surgical pin, then wound dressing can be easily applied, but surgical pin is not adequately stabilized leading to pin site issues
Solution Approach 1:
The stabilizing device is designed with pre-positioned compression members and a modular structure that allows easy application. The device can be quickly placed and adjusted to provide adequate pin stabilization without requiring complex procedures, balancing ease of operation with reliable stabilization.
Solution Approach 2:
The compression members are designed to be adjustable and adaptable to different pin configurations. The stabilizing device can dynamically adjust to provide appropriate pressure and stabilization while maintaining ease of application and removal.
4Manufacturing precision
If complex wound dressing changes are performed, then adequate wound coverage and compression can be achieved, but time is consumed decreasing ability to care for other patients
Solution Approach 1:
The stabilizing device, wound dressing module, and drainage system are merged into a single integrated unit. This combination allows all functions (stabilization, compression, drainage) to be achieved simultaneously in one application, eliminating the need for multiple separate procedures and reducing overall dressing change time.
Solution Approach 2:
The integrated device performs multiple functions simultaneously: it stabilizes the pin, provides symmetrical compression, manages drainage, and covers the wound. This multi-functionality eliminates the need for separate devices and procedures, significantly reducing the time required for dressing changes while maintaining adequate wound coverage and compression.

AI summary
A surgical pin compression wound dressing stabilizing system includes a compressive wound dressing module having a central orifice and radial slit, and a stabilizing device formed of a single piece of material having a longitudinal passageway and a vertical slit, the slits allowing insertion of the module and stabilizing device on a surgical pin at a wound site with the surgical pin dispose in the orifice and passageway. The stabilizing device has an upright post with the longitudinal passageway and a bottom base with a recessed central cavity open at a bottom that receives and mates with an upper portion of the module. The bottom base has a lower outer annular surface surrounding the central cavity for engaging a peripheral rib on the module to enable application of an equal distribution of a downward compressive pressure on the module.
