Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement and installation of magnetic therapeutic devices, particularly endoscopically or laparoscopically, is challenging due to the need for precise magnetic interaction and positioning.
Innovation Solution
An apparatus with an elongate tubular structure and an actuation mechanism that allows a magnet to move between three predetermined locations relative to a therapeutic device interface, enabling controlled magnetic clamping, neutralization, and intermediate force levels for secure placement and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnet is used to magnetically mate a therapeutic device to the apparatus, then secure attachment during installation is achieved, but difficulty in detaching the therapeutic device without tissue injury occurs
Solution Approach 1:
The magnet is made movable relative to the therapeutic device interface through an actuation mechanism, allowing the magnetic clamping force to be dynamically adjusted between a first location (strong clamping for secure attachment) and a second location (reduced or neutralized force for easy detachment). This dynamic repositioning resolves the contradiction between needing strong attachment during installation and easy detachment afterward.
Solution Approach 2:
The magnetic force parameter is changed by altering the position of the magnet relative to the therapeutic device. By moving the magnet between predetermined locations, the magnetic field strength and clamping force are modulated, enabling transition from strong clamping (first location) to reduced/neutralized force (second location), thus resolving the attachment-detachment contradiction.
2Measurement precision
If precise magnetic positioning is required for therapeutic device placement, then placement accuracy is improved, but device complexity increases
Solution Approach 1:
The actuation mechanism is segmented into discrete components including an actuation member, elongate tubular structure, and predetermined location indicators. This segmentation allows the complex positioning function to be broken down into manageable parts, where the actuation member moves along the tubular structure to predetermined locations, achieving precise positioning while keeping the overall device complexity manageable through modular design.
Solution Approach 2:
The actuation member serves as an intermediary element that translates operator input into precise magnet positioning. This intermediary mechanism mediates between the simple actuation input and the complex requirement for precise magnetic positioning, achieving high positioning accuracy through the intermediate steps of the actuation mechanism without requiring direct complex control.

Implementation Method 1
the corresponding first therapeutic device is magnetically mated to the therapeutic device interface by a first magnetic force generated between the magnet and the corresponding first therapeutic device
Implementation Method 2
the corresponding first therapeutic device is magnetically mated to the therapeutic device interface by a second magnetic force generated between the magnet and the corresponding first therapeutic device. The second magnetic force may be less than the first magnetic force
Implementation Method 3
the corresponding first therapeutic device is not magnetically mated to the therapeutic device interface by any magnetic force generated between the magnet and the corresponding first therapeutic device

AI summary
Apparatuses for placement of magnetic therapeutic devices are provided. Such apparatuses may include an actuation mechanism that includes a movable portion that is movable relative to another portion thereof between at least three different predetermined relative locations, each location associated with a different position of a magnet located within a therapeutic device interface of the apparatus. By moving the magnet between the different locations relative to the therapeutic device interface, different amounts of magnetic clamping force between the magnet and a therapeutic device interfaced with the therapeutic device interface may be developed.
