Innovation Solution
An endoscopic device with an electric motor and feeding means integrated within the handpiece, eliminating the need for external wires and allowing for improved ergonomics and maneuverability, featuring a control unit, transmission group, and disposable components to simplify maintenance and reduce contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external motor control systems and connection wires are used, then the device can be controlled from outside the body, but the maneuverability and ergonomics are worsened due to wire encumbrance
Solution Approach 1:
The patent integrates the motor and feeding means directly into the handpiece, merging previously separate external control components with the surgical instrument. This eliminates the connection wire system and improves maneuverability by making the device self-contained and wireless during operation.
Solution Approach 2:
The patent extracts the motor and feeding means from the external control system and relocates them inside the handpiece. This extraction removes the encumbering connection wires and external control mechanisms, allowing for better ergonomics and ease of operation.
2Reliability
If connection wires are used to transmit power and control signals, then external control is enabled, but contamination risks increase due to wire exposure in sterile field
Solution Approach 1:
By merging the motor and feeding means into the handpiece, the patent eliminates the connection wire that would otherwise traverse the sterile field. This integration removes the contamination pathway while maintaining full control functionality.
Solution Approach 2:
The patent employs a disposable handpiece that is sterilized and discarded after a single use. This approach ensures sterility safety by eliminating the need for re-sterilization of components that would otherwise be exposed to contamination risks through wire connections.
3Power
If metallic handpiece with external wires is used, then motor control is achieved, but weight increases limiting operator handling
Solution Approach 1:
The patent combines the motor, feeding means, and control electronics into a single integrated handpiece unit. This merging eliminates the separate external motor and wire system, reducing overall weight while maintaining full motor control functionality for tissue resection.
