Surgical Pin Compression Wound Dressing Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical pin and wire dressing solutions lack symmetrical wound compression, provide an open environment leading to bacterial contamination, and fail to stabilize the pin or wire effectively, resulting in infections and inefficient dressing changes.
Innovation Solution
A surgical pin compressive wound dressing housing with a rigid, non-pliable design and precise pin hole and stem configuration that creates a closed environment for symmetrical compression and stabilization, using a wound dressing housing with a peripheral wall, annular stem, and closure mechanism to maintain pin or wire stability and facilitate easy dressing changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collars, retainers or clips are used to stabilize wound dressing, then the device can be applied to surgical pin sites, but they lack symmetrical wound compression and provide asymmetric pressure distribution
Solution Approach 1:
The device is divided into multiple functional components: a wound dressing housing, a compression mechanism with adjustable arms, and a fixation system. This segmentation allows each component to perform its specific function optimally while achieving symmetrical compression through the coordinated action of the compression arms.
Solution Approach 2:
The compression mechanism incorporates adjustable arms that can be positioned and locked at different angles, allowing dynamic adaptation to achieve symmetrical compression. The arms can be adjusted during application and then fixed in place to maintain consistent symmetrical pressure distribution.
2Ease of operation
If open wound dressing designs are used, then dressing changes can be accessed, but drainage communicates with adjacent skin allowing bacterial contamination
Solution Approach 1:
The wound dressing is nested within a protective housing structure that creates a closed environment. The housing acts as a container that isolates the drainage from the surrounding skin while still allowing controlled access for dressing changes through designated openings or removable components.
Solution Approach 2:
The housing serves as an intermediary barrier between the wound drainage and the patient's adjacent skin. This intermediate structure prevents direct contact between drainage and skin, thereby blocking the pathway for bacterial contamination while still allowing the dressing to be accessed for changes.
3Adaptability or versatility
If flexible wound dressing materials are used, then the dressing can conform to the site, but they lack rigidity to maintain adequate pressure on skin
Solution Approach 1:
The device combines flexible wound dressing materials with a rigid housing structure. The flexible dressing material conforms to the wound site shape and contours, while the rigid housing provides the structural strength necessary to maintain adequate pressure on the skin and prevent collapse or displacement.
Solution Approach 2:
The device separates the functions of conformability and pressure maintenance into different components: the flexible wound dressing material handles conformability, while the rigid housing structure handles pressure maintenance. This segmentation allows each material to optimize its specific function without compromising the other.
4Reliability
If complex dressing change procedures are used, then thorough wound care can be achieved, but it is time consuming and decreases productivity
Solution Approach 1:
The device is designed with modular components that can be independently removed and replaced. The housing, compression mechanism, and dressing materials are segmented into separable units, allowing for quick and easy dressing changes without requiring complex procedures. This modular design maintains thorough wound care while significantly improving efficiency.
Solution Approach 2:
The device is pre-assembled with all necessary components in place before application. The compression mechanism is pre-positioned and adjustable, and the dressing materials are pre-arranged within the housing. This preliminary preparation eliminates the need for complex assembly procedures during dressing changes, reducing time while maintaining care quality.

AI summary
A surgical pin compressive wound dressing housing is described as a device that couples with a wound dressing material or sponge of a specific type and provides a protective closed environment for the surgical point of entry wound where surgical pins or wires are applied. In addition, this device serves to stabilize such surgical pins or wires as they protrude from the surgically made pin site wound upon a patient's skin. Such pins or wires are often utilized, but not limited to, the fixation of fractured bones or when anatomic stabilization is needed. The unique cup like design of the wound dressing housing allows it to couple with a specific type of wound dressing material that has similar geometric features. The top of the wound dressing housing has a central pin hole whereby a pin stem extends upward. Together both the pin hole and pin stem receive the surgical pin or wire which can then be stabilized by the plastic closure snap in the front of the device after the wound dressing housing, and its corresponding wound dressing material, is pressed downward toward the surgical pin or wire point of entry wound. A hinge in the back of the device allows the wound dressing housing and its associated pin stem to split into equal right and left halves upon opening the device. This allows the device to be placed around the surgical pin or wire in question. By utilizing both the left and right hand clasps the user can close the device thus engaging the closure snap in the front of the wound dressing housing which secures the device in the closed position.
