Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate surgical instruments are used for tissue dissection, fluid suction, and smoke evacuation, then each function can be performed effectively, but instrument clutter increases and surgical field visibility is reduced
Solution Approach 1:
The patent combines tissue dissection, fluid suction, and smoke evacuation functions into a single integrated surgical instrument. The cutting end incorporates both a cutting edge for tissue dissection and an aperture for fluid/smoke evacuation, eliminating the need for multiple separate instruments and reducing surgical field clutter
Solution Approach 2:
The surgical instrument is designed with multi-functionality to perform cutting, fluid suction, and smoke evacuation simultaneously. The unified design allows a single instrument to replace multiple specialized tools, improving surgical field visibility while maintaining all necessary functions
2Productivity
If a circular aperture is used at the cutting end, then the structure is simple, but fluid and smoke evacuation efficiency is reduced
Solution Approach 1:
The patent employs an elliptical aperture instead of a circular one at the cutting end. This asymmetric shape optimizes the evacuation pathway for fluids and smoke, improving removal efficiency while the aperture remains integrated into the overall simple cutting end structure
3Ease of operation
If the evacuation hose is connected at a perpendicular position, then the connection is straightforward, but it interferes with the surgical procedure
Solution Approach 1:
The external port is positioned at an angled orientation rather than perpendicular to the device axis. This asymmetric positioning allows the evacuation hose to be routed away from the surgical field, reducing interference with the surgical procedure while maintaining ease of connection

Function Achieved in This Case
Enhances surgical efficiency by reducing instrument clutter and ensuring clear visualization during procedures, improving safety and effectiveness.
Implementation Method 1
an aperture for evacuation of a fluid on the cutting end
Implementation Method 2
the second portion being a handle and having a second fluidic channel that is in fluidic communication with the first fluidic channel
Implementation Method 3
The external port may include a swivel connection to the handle body allowing the evacuation hose to swivel as the device is moved

AI summary
A modular surgical device is disclosed for efficient tissue dissection and fluid evacuation during surgical procedures. The device comprises a first portion with a cutting end tapered to a sharpened tip, a fluidic channel, and a uniquely shaped aperture. The aperture features an elliptical cross-section oriented at an angle relative to the device's longitudinal axis, potentially enhancing fluid flow dynamics. A releasable locking assembly securely connects the first portion to a second handle portion containing a fluidic channel and an angled external port for evacuation hose attachment. The device's modularity allows for customization and its angled port configuration is designed to minimize interference during surgical procedures.
