Electromagnetic Tissue Compression Device for Anastomosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anastomosis devices for creating side-to-side connections between gastrointestinal tract portions, such as between the duodenum and ileum, lack effective methods for secure and temporary tissue compression to facilitate nutrient-rich chyme diversion, often requiring invasive procedures and prolonged tissue necrosis for device release.
Innovation Solution
A tissue compression device with electromagnets that are initially non-magnetized for ease of handling, activated within the body to clamp intestinal tissue, causing ischemia and eventual necrosis, allowing the device to be released and passed through the gastrointestinal tract, while providing a secure anastomosis without the need for permanent fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anastomosis devices are used to compress tissue, then secure tissue compression is achieved, but the devices require permanent fixation and invasive procedures for removal
Solution Approach 1:
The patent replaces traditional mechanical fixation systems with an electromagnetic system. Electromagnets provide secure tissue compression through magnetic attraction while allowing non-invasive removal by simply turning off the power source, eliminating the need for surgical removal procedures required by mechanical devices
Solution Approach 2:
The patent changes the operational state of the compression mechanism from permanently mechanical to controllable electromagnetic. By controlling the electrical power supply to electromagnets, the compression force can be activated or deactivated at will, enabling temporary secure fixation that can be easily released without invasive procedures
2Ease of operation
If electromagnets are used for tissue compression, then non-invasive device removal is enabled, but the device complexity increases
Solution Approach 1:
The electromagnet system serves multiple functions: it provides secure tissue compression during the anastomosis healing period and then enables easy device removal by simply deactivating the magnetic field. This multi-functionality justifies the increased complexity by eliminating separate fixation and removal mechanisms
Solution Approach 2:
The electromagnetic system is self-regulating through controlled power supply. The electromagnets automatically maintain compression force when powered and release when power is cut, requiring no additional mechanical release mechanisms or complex control systems beyond simple power control
3Stability of the object's composition
If permanent fixation devices are used, then stable anastomosis is achieved, but tissue damage and necrosis time are prolonged
Solution Approach 1:
The electromagnetic compression is applied periodically or temporarily only during the critical healing phase needed to establish the anastomosis. After the tissue bond forms, the magnetic field is deactivated, allowing the device to be removed once the anastomosis is stable, thereby reducing prolonged tissue exposure and necrosis time while maintaining necessary stability during the critical period
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively creates a secure anastomosis by compressing intestinal tissue with electromagnets, inducing necrosis and allowing the device to be naturally expelled, thereby bypassing the jejunum and enhancing nutrient flow, while minimizing invasive procedures and tissue damage.
