Clip Applier Adapter Locking Structure for Fool-Proof Cartridge Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection structure between the clip-cartridge assembly and the adapter in surgical clip applicators is complex, making assembly and disassembly inconvenient, leading to low operation efficiency and potential errors.
Innovation Solution
The adapter features a lock mechanism that allows the clip-cartridge assembly to be easily plugged in and pulled out by pulling an operation member in the proximal direction, with a lock mechanism ensuring secure attachment after insertion, preventing erroneous mounting and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clip applier is designed to be multifunctional (capable of deploying both PCL and ACL grafts), then the versatility of the device is improved, but the device complexity increases and requires multiple adapters
Solution Approach 1:
The adapter is designed with a universal interface that can accommodate different graft types (PCL and ACL) through a single standardized connection system. The adapter body includes a universal receptacle that can receive different types of grafts, allowing one adapter to serve multiple functions rather than requiring separate adapters for each graft type.
Solution Approach 2:
The adapter is divided into distinct functional segments: a reception portion for receiving the graft, a connection portion for connecting to the clip applier, and a delivery portion for delivering the graft. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity and modularity.
2Ease of operation
If the adapter includes a reception portion, connection portion, and delivery portion as separate functional elements, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The reception portion, connection portion, and delivery portion are merged into a single integrated adapter body. These functional elements are combined in one component rather than being separate parts, which simplifies the overall device structure while maintaining the operational benefits of having distinct functional zones within the unified adapter.
3Ease of repair
If the adapter is designed to be detachably connected to the clip applier, then the ease of repair and replacement is improved, but the reliability of the connection may be worsened
Solution Approach 1:
The connection between the adapter and clip applier is designed to be dynamically changeable - allowing easy detachment when needed while maintaining a secure, reliable connection during use. The detachable connection mechanism incorporates features that ensure firm engagement during operation but allow controlled separation when required for repair or replacement.

AI summary
A clip applier, comprising a clip compartment assembly (1) and an adapter (2). A locking structure is provided in the clip compartment assembly (1). The adapter (2) comprises an adapter housing and a locking mechanism, wherein an operating member on the adapter housing moves towards a proximal end under the action of an external force in the direction of the proximal end, such that the locking mechanism can allow the clip compartment assembly (1) of the clip applier to be inserted into and pulled out of the adapter housing; and when the external force in the direction of the proximal end disappears, the locking mechanism impels the operating member to move towards a distal end to the original position and can match with the locking structure on the clip compartment assembly (1) so as to lock the clip compartment assembly (1) in the adapter (2). The clip compartment assembly (1) is convenient to assemble and disassemble and has a fool-proofing effect.
