Wearable Surgical Absorptive Device for Gauze Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gauze mesh used in surgical procedures is often loose, making it difficult to handle and increasing the risk of misplacement within patients, which can be hazardous and result in serious health issues.
Innovation Solution
A wearable surgical device with a folded absorptive material that forms a pocket for the hand, secured by flexible connecting portions, providing improved grip and reducing the likelihood of misplacement by being worn on the hand rather than held.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional loose gauze mesh is used, then the device can be easily manufactured and applied, but it is difficult to hold and prone to misplacement within the patient
Solution Approach 1:
The gauze material is transformed from a two-dimensional loose sheet into a three-dimensional wearable device that envelops the hand, adding the dimension of spatial configuration to prevent misplacement while maintaining ease of handling through the wearable structure
Solution Approach 2:
The gauze material is configured as a flexible wearable shell that conforms to the hand shape, providing secure retention of the gauze on the surgeon's hand while maintaining the soft, compliant characteristics necessary for surgical applications
2Reliability
If loose gauze mesh is used, then the material is simple and flexible, but it is susceptible to being misplaced and retained within the patient
Solution Approach 1:
The wearable device is segmented into distinct functional components including the absorptive gauze portion, connecting portions for securing, and wrist cuff for retention, allowing each segment to perform its specific function while collectively preventing misplacement
Solution Approach 2:
The gauze material is folded and nested within itself to form a pocket structure that receives the hand, creating a nested configuration that secures the gauze in place while maintaining accessibility for surgical use
3Ease of operation
If conventional gauze is held in hand, then no additional structure is needed, but control and grip stability are insufficient
Solution Approach 1:
The wearable device incorporates flexible connecting portions and a wrist cuff that dynamically adapt to the surgeon's hand movements, providing stable grip and control throughout the surgical procedure while allowing necessary flexibility for dexterous manipulation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wearable device enhances control and reduces the risk of gauze misplacement during and after surgery, improving safety by providing a secure and efficient means to manage biological fluids and tissue handling.
Implementation Method 1
a first absorptive material that has a first end, a second end, an outer surface, an inner surface

AI summary
Methods of wearing a surgical device during a surgical procedure include putting the surgical device on a hand by passing the hand through a wrist cuff formed of a stretchable material of the surgical device and positioning the hand inside a first absorptive material of the surgical device that has been folded and secured together along at least a portion of its sides to form a pocket so that the surgical device is worn on the hand. The first absorptive material of the surgical device can be brought into contact with an internal surface of a patient while the surgical device is worn on the hand. Biological fluids in the vicinity of the surgical device can be absorbed by the first absorptive material when the first absorptive material is in contact with the internal surface of the patient.
