Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic biopsy tools are inefficient, destructive to tissue samples, require multiple instrument exchanges, and lack integrated anesthesia and hemostasis capabilities, leading to suboptimal specimen quality and increased surgical costs and patient discomfort.
Innovation Solution
A multi-functional endoscopic biopsy forceps with insulated jaws that use diathermy for precise tissue cutting and hemostasis, integrated anesthesia delivery, and a sealed biopsy cup for specimen collection, allowing simultaneous tissue acquisition and processing without general anesthesia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional rigid metal instruments are used for biopsy, then tissue specimen quality is improved, but patient requires general anesthesia and hospital stay
Solution Approach 1:
The patent replaces rigid mechanical biopsy instruments with a flexible endoscopic device that uses electrocautery (electrical energy) to cut and remove tissue. The flexible tube can be passed through the urethra without general anesthesia, while the electrocautery function provides precise tissue sampling with hemostasis, eliminating the need for rigid instruments and general anesthesia.
Solution Approach 2:
The endoscopic device integrates multiple functions into a single instrument: flexible insertion through urethra, electrocautery tissue cutting, hemostasis, and tissue sampling. This multi-functional device can perform biopsy procedures without requiring separate rigid instruments and general anesthesia, while maintaining tissue specimen quality through controlled electrocautery cutting.
2Ease of operation
If flexible biopsy instruments are used, then patient can have outpatient procedure, but tissue specimen quality deteriorates
Solution Approach 1:
The patent replaces mechanical cutting mechanisms with electrocautery-based tissue removal. The electrocautery function allows flexible instruments to achieve precise tissue sampling by using controlled electrical current to cut and remove tissue, maintaining specimen quality while enabling outpatient procedures with flexible instrumentation.
3Adaptability or versatility
If multiple instruments are used for different functions, then comprehensive treatment is achieved, but device complexity and procedure time increase
Solution Approach 1:
The patent merges multiple functions into a single endoscopic device: the flexible tube serves as both the insertion channel and working channel, the electrocautery system provides both cutting and hemostasis, and the suction system integrates with the same channel. This consolidation eliminates the need for multiple separate instruments for anesthesia, biopsy, and hemostasis, reducing procedure complexity while maintaining comprehensive treatment capability.
Solution Approach 2:
The endoscopic device is designed as a universal instrument that can perform multiple functions: local anesthesia delivery through the flexible tube, electrocautery tissue cutting, hemostasis, and tissue sampling. This multi-functional design replaces the need for multiple specialized instruments, simplifying the procedure while providing comprehensive treatment options.
4Device complexity
If conventional single-channel cystoscope is used, then device simplicity is maintained, but multiple instrument exchanges are required
Solution Approach 1:
The patent segments the single working channel into multiple functional channels within the flexible tube: a first channel for anesthesia delivery, a second channel for electrocautery tissue cutting, and a third channel for suction and hemostasis. This segmentation allows multiple instruments to be simultaneously positioned through the flexible tube without requiring instrument exchanges, improving procedure efficiency while maintaining the flexibility and simplicity of the endoscopic approach.
