Artificial Implant Locking Mechanism for Smooth Release and Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the connection between artificial implants and catheter assemblies, such as direct clamping or wire control, require improvements in locking and unlocking mechanisms to ensure smooth expansion, release, and withdrawal of the implant.
Innovation Solution
A control mechanism for artificial implants featuring a base with a locking area, a pulling wire, and a rotatable locking member that engages or disengages with the base to lock or unlock the implant, allowing for precise control and smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire control method is used to bind and lock the artificial implant to the catheter assembly, then the implant can be securely held in compressed state, but the control mechanism becomes complex and the locking/unlocking process is not smooth
Solution Approach 1:
The locking mechanism is divided into separate functional components: a locking member with positioning portions, a base with locking areas, and a pulling wire. The locking member can rotate independently to engage or disengage from the base, allowing simplified control of the locking/unlocking process while maintaining secure implant holding.
Solution Approach 2:
The locking member is designed to be rotatable relative to the base, transitioning between locked and unlocked positions. This dynamic mechanism allows smooth control of the implant's restraint state through simple rotational motion, reducing the complexity of the control mechanism while ensuring reliable locking.
2Reliability
If existing flexible component locking method is used, then the implant can be restrained, but the expansion and release process is not smooth
Solution Approach 1:
The rotatable locking member provides smooth transitional motion between locked and unlocked states. The positioning portions on the locking member engage with or disengage from the locking areas on the base through continuous rotation, enabling smooth expansion and release of the implant without abrupt movements or sticking.
Solution Approach 2:
The pulling wire acts as an intermediary element that transmits force from the operator to the locking member. By pulling or releasing the wire, the locking member rotates accordingly, mediating the control of the implant's restraint state and ensuring smooth operation during expansion and release.
3Device complexity
If direct clamping method is used to connect implant and catheter assembly, then the structure is simple, but the control over implant deployment is insufficient
Solution Approach 1:
The connection structure is segmented into the base, locking member, and pulling wire components. This segmentation maintains relative structural simplicity while enabling sophisticated control functions. The locking member's rotation provides precise control over implant deployment without requiring a complex overall structure.
Solution Approach 2:
The locking member automatically engages with the base when the implant is compressed and positioned correctly. The positioning portions self-align with the locking areas, providing automatic locking without requiring complex external control mechanisms, thus maintaining structural simplicity while improving operational control.

AI summary
Disclosed in the present application are a control mechanism, a locking mechanism, a loading method, and a pre-loading method for an artificial implant. The control mechanism for the artificial implant includes a base, a pulling wire, and a locking member. The base is configured with a locking hole. The pulling wire has a free end that can be passed through, wound around, or detached from the artificial implant. The locking member and the base are rotatably engaged to lock the free end of the pulling wire. After the control mechanism is optimized, it can cooperate to realize the control of the expansion, release, or withdrawal process of the artificial implant in the body, which is more suitable for internal work than existing structures.
