Reusable Sling Delivery Device Segmentation Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sling delivery devices are typically single-use and difficult to disassemble and sterilize, posing health and safety hazards due to embedded bodily fluids and contaminating substances, which limits their reusability in surgical procedures.
Innovation Solution
A medical device with a needle member and handle, featuring a pusher member that can move from a first to a second position during surgery, is designed to be removably coupled and decoupled, allowing for easy disassembly, sterilization, and reassembly for subsequent use, utilizing a track portion with recesses and protrusions for secure engagement and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional sling delivery devices are designed for single-use, then ease of sterilization is improved, but device complexity increases and cost-effectiveness deteriorates
Solution Approach 1:
The delivery device is divided into separable components including a handle assembly, a needle assembly, and a sling assembly. Each component can be independently sterilized and reprocessed, simplifying the sterilization process while maintaining device functionality. The separable design allows each segment to be treated according to its specific requirements.
Solution Approach 2:
The device incorporates dynamic coupling mechanisms that allow components to be easily assembled and disassembled. The handle assembly includes a release mechanism that enables straightforward separation of the needle assembly, facilitating repeated sterilization cycles without complex procedures.
2Reliability
If conventional sling delivery devices are constructed for single-use, then health and safety hazards are reduced, but productivity deteriorates due to disposal requirements
Solution Approach 1:
By segmenting the device into sterilizable components, the system maintains health and safety through proper reprocessing while enabling reuse. The separable design allows complete disassembly for thorough sterilization, eliminating contamination risks associated with single-use disposal limitations.
Solution Approach 2:
The device is designed for recovery and reuse rather than disposal. Components are constructed to withstand multiple sterilization cycles, and the assembly/disassembly mechanisms enable efficient reprocessing, transforming the device from a single-use item to a reusable instrument that improves productivity.
3Reliability
If conventional sling delivery devices are made difficult to disassemble, then reliability during surgery is improved, but ease of operation deteriorates for reprocessing
Solution Approach 1:
The coupling between handle assembly and needle assembly employs a dynamic release mechanism that provides stable engagement during surgical procedures but allows easy separation when needed. The mechanism maintains firm connection under operational forces while enabling straightforward disassembly for sterilization through a simple release action.
Solution Approach 2:
The device is segmented into modular assemblies with standardized coupling interfaces. These interfaces are designed to provide reliable connection during use but allow clean separation for reprocessing, balancing surgical reliability with ease of disassembly through thoughtful interface design.

AI summary
According to an aspect, a medical device may include a needle member, and a handle coupled to the needle member. The handle may define a track portion. The medical device may also include a pusher member having a sheath disposed around a portion of the needle member, and an extension member being movably coupled to the track portion of the handle such that the pusher member is configured to move from a first position to a second position during a surgical procedure. The pusher member may be removable from the handle. The sheath may define a slot, and the pusher member may be removable from the needle member through the slot.
