Dual Clamp Effector Endoscope for Precise Lesion Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operation devices for performing procedures on lumens in the body often rely on a single effector for incision and cauterization, which lacks precision and efficiency, and have complex manipulation structures, making it difficult for users to conduct procedures effectively.
Innovation Solution
An operation device utilizing two clamp-type effectors connected with electric lines, where the second effector is longer to facilitate precise incision and the first effector holds the lesion, along with simplified manipulation handles to manage the effectors, allowing for electrothermal treatment of lesions within the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single needle or knife or effector is used to incise or cauterize a lesion portion, then the treatment can be performed with a simple device structure, but the precision and effectiveness of removing lesion tissue from normal tissues is insufficient
Solution Approach 1:
The device divides the treatment function into two separate clamp-type effectors: one for clamping/holding the lesion portion and another for incision/cauterization. This segmentation allows each effector to be optimized for its specific function, improving precision while keeping the overall device manageable through modular design
Solution Approach 2:
The device integrates multiple functions into a single system by combining clamping, incision, and cauterization capabilities in one endoscopic device. The two effectors work together to achieve both mechanical manipulation and thermal/electrical treatment, reducing the need for multiple separate devices
2Ease of operation
If conventional effectors with complicated manipulation structure are used, then the device may have sufficient functionality, but it becomes difficult for the user to conduct procedures effectively
Solution Approach 1:
The manipulation handles of both clamp-type effectors are integrated into a single unified handle assembly, allowing the operator to control both effectors simultaneously with one hand. This merging of control mechanisms simplifies the manipulation structure while maintaining full functionality of both effectors
Solution Approach 2:
A wire transmission mechanism serves as an intermediary between the manipulation handle and the two effectors, transmitting mechanical movements from the handle to both effectors independently. This intermediary system allows complex effector movements to be controlled through simple handle manipulations
