Plastic Support for Organ Injection Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for injecting foreign substances into organs, such as kidneys, are restricted by the need for the organ to be attached to an animal body, making the process difficult and invasive, especially when the injection target zone is not easily accessible.
Innovation Solution
The method involves bringing at least a portion of the organ removed from an animal body into contact with a member having plasticity, such as a gel, to position the organ and allow easy injection of a foreign substance into the desired area without causing significant damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the organ is removed from the animal body for injection, then the operation flexibility and timing are improved, but the difficulty of puncture and organ damage risk increase
Solution Approach 1:
The patent introduces a support member as an intermediary between the needle and the organ. The support member holds the organ in a fixed position and provides a stable target for puncture, making the injection process easier while allowing the organ to be removed from the animal body. This resolves the contradiction by mediating between the need for organ removal (flexibility) and the difficulty of puncturing small, soft organs.
Solution Approach 2:
The support member creates a simplified model or representation of the organ's position and structure, allowing the operator to work with a stable, positioned target rather than the actual fragile organ alone. This copying approach enables easier puncture operations while maintaining the benefits of organ removal.
2Ease of operation
If the needle punctures from the exposed surface to reach the injection target zone, then the injection can be performed, but the organ is seriously damaged by the injection path
Solution Approach 1:
The support member enables injection from a different spatial dimension or angle. By positioning the organ on the support member, the needle can approach the injection target zone from an optimal direction that minimizes damage to surrounding tissue, rather than being constrained to puncture from the exposed surface alone.
Solution Approach 2:
The organ is pre-positioned on the support member before injection, allowing the injection path to be planned and optimized in advance. This preliminary positioning enables the needle to reach the target zone through the least damaging path, reducing harm to the organ while maintaining accessibility.
3Object-affected harmful factors
If the organ is held softly to avoid damage during puncture, then organ integrity is improved, but the puncture operation becomes more difficult
Solution Approach 1:
The support member acts as an intermediary that holds the organ, distributing the handling stress and providing a stable platform for puncture. This allows the operator to puncture the organ more easily while the support member protects the organ from excessive manipulation damage, resolving the contradiction between easy puncture and organ integrity.
