Implant Positioning Device Sliding Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional implant placement equipment is inefficient due to slow assembly and disassembly, fragility, bulkiness, and limited applicability to complex shapes, which hinders rapid and precise implant placement and interferes with ongoing surgical interventions.
Innovation Solution
A minimally invasive equipment with a gripping instrument and a blocking element featuring a sliding connection, utilizing hooking means and dovetail projections for secure implant fixation, allowing rectilinear or circular movement, and made from composite materials for biocompatibility and recyclability, enabling rapid implant placement and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded portion is used to engage with a tapped bore for implant fixation, then the implant can be securely retained, but the assembly and disassembly operations become slow and time-consuming
Solution Approach 1:
The patent replaces the threaded mechanical engagement system with a friction-based retention system. The implant is retained through friction between the implant surface and the internal surface of the tubular body, eliminating the need for threading and tapping operations. This substitution dramatically reduces assembly and disassembly time while maintaining secure implant retention throughout the surgical procedure.
2Reliability
If an external locking tube is used to secure the implant on the arms, then the implant can be locked, but the equipment becomes bulky and the locking system is not suitable for single-use equipment
Solution Approach 1:
The patent merges the locking function into the tubular body structure itself. The friction-based retention mechanism is integrated directly into the walls of the tubular body, eliminating the need for separate external locking tubes or pieces. This integration reduces equipment complexity and size while providing reliable implant retention throughout the surgical procedure.
3Reliability
If an external locking piece is placed around the arms to secure the implant, then the implant can be locked, but the equipment becomes fragile due to the additional external part
Solution Approach 1:
The patent integrates the locking function directly into the tubular body structure, eliminating the need for separate external locking pieces. The friction-based retention mechanism is built into the walls of the tubular body, creating a more robust and integrated structure that is better suited for single-use equipment while maintaining reliable implant retention.
4Reliability
If an external locking system is used, then the implant can be secured, but the equipment cannot be used with complex shapes as it is only suitable for straight shapes
Solution Approach 1:
The patent creates a universal friction-based retention system within the tubular body that can accommodate various implant shapes and sizes. The internal surface of the tubular body is designed to provide friction retention for different geometries, making the equipment adaptable to complex shapes and multiple surgical applications rather than being limited to straight shapes only.
