Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyors for implant loading in medical procedures, such as lung volume reduction surgery for emphysema, are complicated and require auxiliary tools, making the operation cumbersome and inefficient.
Innovation Solution
A conveyor system comprising a conveying handle, a tubular core wire, and a conveying cable, with control mechanisms that allow the core wire to extend into the implant to straighten it and withdraw to restore its natural shape, enabling simple and tool-free loading and release of the implant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tubular preloading device is used to load the curled implant, then the implant can be loaded into the conveyor, but the operation becomes complicated and requires auxiliary tools
Solution Approach 1:
The patent combines the preloading device and conveyor into a single integrated structure. The conveying cable's tubular body serves dual functions as both the conveyor structure and the preloading device, eliminating the need for separate auxiliary loading tools and simplifying the overall system.
Solution Approach 2:
The conveying cable is designed to perform multiple functions: it serves as the structural component of the conveyor, provides the loading channel for the implant, and acts as the preloading device through its tubular structure. This multi-functionality eliminates the need for dedicated auxiliary loading devices.
2Shape
If the core wire extends into the implant to straighten it, then the implant can be conveyed in a linear shape, but the control mechanism becomes more complex
Solution Approach 1:
The core wire is nested within the conveying cable, allowing it to extend through the tubular body to interact with the implant. This nested configuration enables shape control functionality without adding external complexity to the control mechanism.
Solution Approach 2:
The core wire acts as an intermediary element that transmits control forces from the proximal end to the implant at the distal end. By manipulating the core wire's extension and retraction, the implant's shape can be controlled without requiring complex direct manipulation mechanisms.
3Manufacturing precision
If multiple control mechanisms are added to control core wire movement, then the implant shape and position can be precisely controlled, but the operating complexity increases
Solution Approach 1:
The control mechanism employs dynamic locking and unlocking states rather than fixed positions. The locking component can be engaged or disengaged to control core wire movement, providing precise positioning when locked while maintaining operational simplicity through the binary locked/unlocked states.
Solution Approach 2:
The locking mechanism is designed to be self-contained within the conveying handle, with the locking component automatically engaging with the guide rail structure. This self-service design eliminates the need for external locking tools or complex multi-step procedures.
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
Facilitates the straightforward loading, conveying, and release of implants without additional tools, enhancing the efficiency and safety of the implantation process by controlling the implant's shape and movement within the conveyor system.
Implementation Method 1
Since the implant is curled and has certain elasticity in a natural state, each curled part of the implant can be constrained into a linear shape by external force
Implementation Method 2
the first control controls the core wire to withdraw from the implant to restore the implant to the preset shape

AI summary
A conveyor for an implant having at least one cavity, including a conveying handle, a conveying cable, and a core wire. The conveying cable is a tubular body, a proximal end of the core wire is connected to the conveying handle, and a distal end of the core wire penetrates a distal end of the conveying cable from a proximal end of the conveying cable; a first control is provided on the conveying handle, and when the implant is connected to the distal end of the conveying cable, the first control controls the distal end of the core wire to extend into the implant to straighten the curved implant, or the first control controls the core wire to withdraw from the implant to restore the implant to a preset shape. The conveyor can load and release the implant on the conveyor, and be used in the entire implanting process.
