Reusable Mesh Deployment Device Actuation Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh deployment devices for endoscopic surgery often require the mesh to be pre-attached, leading to increased shipping costs and potential mesh deformation, and are typically designed for single use, limiting their practicality and reusability.
Innovation Solution
A mesh deployment device with separate actuation and mesh deployment units, allowing the mesh to be securely attached and detached, enabling the mesh deployment unit to be reused and reducing shipping costs by maintaining the mesh's integrity during storage and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mesh is pre-attached to the deployment device, then the clinician's convenience is improved and mesh damage is prevented, but shipping costs increase and the device becomes single-use
Solution Approach 1:
The deployment device is divided into separate components: a reusable actuation unit and disposable mesh deployment units. This segmentation allows the mesh to be attached to the deployment unit without being permanently integrated, enabling the mesh to be securely held during shipping while allowing cost-effective disposal of the mesh deployment unit after a single use.
2Reliability
If the mesh is pre-attached to the deployment device, then mesh damage is prevented, but the device is limited to single use
Solution Approach 1:
The system is segmented into a reusable actuation unit and a disposable mesh deployment unit. The mesh is attached to the deployment unit with sufficient security to prevent damage during shipping and storage, but the deployment unit itself is designed for single use and disposal, while the actuation unit can be reused with different mesh deployment units.
Solution Approach 2:
The mesh deployment unit acts as an intermediary between the reusable actuation unit and the mesh. It provides a secure attachment mechanism for the mesh during shipping and storage, then facilitates controlled deployment during surgery, after which it is disposed of while the actuation unit remains reusable.
3Reliability
If the frame is shipped in an open condition, then mesh integrity is maintained, but shipping costs increase
Solution Approach 1:
The mesh deployment unit is designed to nest within itself or within packaging when collapsed, allowing the frame to be shipped in a collapsed condition without compromising mesh integrity. The mesh remains protected during shipping in the collapsed state, and the nested configuration reduces shipping volume and costs.
4Adaptability or versatility
If separate actuation and mesh deployment units are used, then reusability is improved and shipping costs are reduced, but device complexity increases
Solution Approach 1:
The actuation unit is designed as a universal, reusable component that can interface with multiple different mesh deployment units. This multi-functionality allows the same actuation unit to be used with various mesh types and sizes, reducing overall system complexity despite the separation into multiple components.

AI summary
A mesh deployment device having separate mesh deployment and actuation units is provided. A mesh deployment device includes an actuation unit and a mesh deployment unit configured to be releasably secured to the actuation unit. When the mesh deployment unit is secured to the actuation unit, a first actuation of the actuation unit moves the mesh deployment unit from an expanded condition to a collapsed condition and a second actuation of the actuation unit moves the mesh deployment unit from the collapsed condition to the expanded condition. The mesh deployment device may further include a mesh releasably secured to the mesh deployment unit. A third actuation of the actuation unit may release the mesh from the mesh deployment unit. Also provided is a kit including multiple mesh deployment units.
