Multi-firing Medical Tissue Clip Release Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical tissue clips require multiple replacements and relocations during surgeries for large wounds or multiple bleeding spots, leading to prolonged surgery times and potential missed hemostasis due to excessive bleeding.
Innovation Solution
A release device for medical tissue clips comprising an outer tube, a control wire, and a release member, where the tissue clip is movably connected to the control wire and can be sequentially released using a push and pull mechanism, allowing for efficient deployment and retrieval of multiple clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-firing tissue clips are used for large wounds or multiple bleeding spots, then the clips can be reliably deployed, but the surgery time is prolonged due to multiple replacements and relocations
Solution Approach 1:
The patent combines multiple single-firing tissue clips into a single multi-firing device. The delivery device can sequentially deploy multiple tissue clips along a control wire, allowing all clips to be deployed in one surgical intervention rather than requiring multiple separate insertions and replacements of individual clips.
Solution Approach 2:
The delivery device is designed with multi-functionality to handle multiple tissue clips simultaneously. It can deploy, retrieve, and reposition multiple clips along a single control wire, making one device capable of performing the work of multiple single-firing devices and reducing the need for repeated surgical interventions.
2Ease of manufacture
If multiple single-firing tissue clips are deployed sequentially, then each clip can be precisely positioned, but the workload and complexity of the surgery increase
Solution Approach 1:
The delivery device is segmented into functional modules: a control wire for positioning, a release member for deploying clips, and a mechanism for sequential advancement. This segmentation allows the complex function of deploying multiple clips to be broken down into manageable, coordinated actions that can be controlled from a single device.
Solution Approach 2:
The control wire acts as an intermediary element that connects the operator's control to multiple tissue clips. By threading the control wire through all clips and using a release member to advance along the wire, the system mediates between the single operator input and multiple clip deployment actions, simplifying the overall surgical procedure.
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 device significantly reduces surgery time by enabling rapid and efficient deployment and retrieval of tissue clips, minimizing the risk of excessive bleeding and improving hemostasis in gastrointestinal surgeries.
Implementation Method 1
the clip base comprises an elastic member, the elastic member is configured to be in a pressed state when it is located in the outer tube, and in an opened state upon detachment from the outer tube so as to abut against an end portion of the outer tube to prevent the tissue clip from retreating into the outer tube
