Integrated Surgical Debridement and Suction Control Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical procedures require frequent device replacement and complex operational procedures due to the use of separate suction, irrigation, and debridement devices, which complicates the surgeon's job and compromises patient safety.
Innovation Solution
A multifunctional medical device with integrated suction, irrigation, and debridement capabilities, featuring a control module with a suction control portion and switching unit that allows simultaneous debridement and suctioning, and includes a stopping unit to prevent unintended activation of the operation portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate suction, irrigation, and debridement devices are used, then each function can be performed effectively, but the device complexity and operational complexity increase significantly
Solution Approach 1:
The patent combines suction, irrigation, and debridement functions into a single integrated medical device. The device includes a handle assembly with a suction/irrigation system and a shaft assembly with a debridement element, allowing all three functions to be performed simultaneously through one device rather than requiring multiple separate devices.
Solution Approach 2:
The medical device is designed as a universal tool that can perform multiple surgical functions. The handle assembly can switch between suction mode and irrigation mode, while also supporting debridement operations, making it a multi-functional device that reduces the need for multiple specialized instruments.
2Reliability
If multiple separate devices are used for different surgical functions, then each function can be optimized, but the frequency of device replacement increases
Solution Approach 1:
The patent merges suction, irrigation, and debridement capabilities into a single device, eliminating the need to repeatedly remove and replace different devices during surgery. The integrated design allows the surgeon to maintain all necessary functions throughout the procedure without interruption for device changes.
3Ease of operation
If the suction control portion can freely move to activate the operation portion, then operational flexibility is improved, but the risk of accidental activation increases
Solution Approach 1:
The patent implements a stopping unit that acts as a safety barrier to prevent the suction control portion from moving into the activated position unless intentionally and deliberately actuated. This preliminary protective measure blocks unintended activation while still allowing controlled activation when required, balancing safety with operational flexibility.
4Productivity
If a single multifunctional device is used, then device replacement frequency decreases, but the device complexity increases
Solution Approach 1:
The patent divides the multifunctional device into distinct modular components: a handle assembly containing the suction/irrigation control mechanisms and a shaft assembly containing the debridement element. This segmentation allows each component to be optimized for its specific function while being part of an integrated system, managing overall complexity through modular design.

AI summary
A medical device includes an outer tube, an operation portion at least partially located in the outer tube and a control portion having a channel communicated with the outer tube along the first direction. The second end of the control portion is coupled with the first end of the outer tube, so that the channel and the outer tube are communicated with each other along the first direction. The control portion includes a control module including a suction control unit having a stopping unit and configured to move along a second direction which is different form the first direction, a suction port actuator located at a side opposite to the suction control unit with the channel therebetween and a switching unit configured to switch the work status of the operation portion. The suction port actuator is configured to be activated by the suction control unit.
