Marker Fastening Assembly for Stable Surgical Frame Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marker fixation systems for surgical navigation require complex assembly processes and lack stability during minimally invasive surgeries.
Innovation Solution
A fastening device with an integrated design that allows direct attachment to a positioning pin, featuring a fixing holder, frame, and locking member, which includes a limiting block and supporting member, enabling secure and easy connection without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple combining parts are used to fix markers onto a frame, then the markers can be securely attached, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple separate components (fixing holder, frame, and locking member) into an integrated fastening device where the locking member is disposed on the frame and directly engages with the fixing holder, eliminating the need for additional connecting parts and simplifying the assembly process while maintaining secure marker attachment
2Stability of the object's composition
If multiple connecting parts are used to secure the frame to the positioning pin, then the connection can be stable, but the overall structure becomes more complex and harder to operate
Solution Approach 1:
The patent merges the fixing holder and frame into an integrated assembly where the locking member on the frame directly engages with the fixing holder, creating a stable connection to the positioning pin without requiring additional connecting parts, thus simplifying operation while maintaining connection stability
3Ease of operation
If an integrated design is used to simplify assembly, then the operation becomes easier, but the stability and security of the marker fixation may be compromised
Solution Approach 1:
The patent incorporates a movable locking member that can be dynamically adjusted between locked and unlocked positions, allowing the frame to be securely fixed to the positioning pin when locked while maintaining ease of operation through simple locking/unlocking actions
Solution Approach 2:
The locking member acts as an intermediary element between the frame and fixing holder, providing a secure mechanical engagement that ensures stable marker fixation while maintaining the simplicity of the integrated design through direct engagement without additional components

AI summary
A fastening device including a fixing holder, a frame, and a locking member. The fixing holder includes a main base, a limiting block, and a supporting member. The main base includes a mounting portion that is disposed at a side thereof. The mounting portion has a recess. The limiting block is disposed in the recess. The limiting block has a limiting groove. The supporting member is connected to the main base and corresponds to the limiting block. The frame includes a limiting column, and the frame is assembled to the fixing holder through placing the limiting column within the limiting groove. The locking member is disposed at the supporting member and abuts the limiting column for fixing the frame in place.
