Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical tool holders for surgical operations, particularly in artificial joint surgery, are complex, costly, and prone to failure due to misalignment of impact forces, leading to damage and safety risks.
Innovation Solution
A holder with a concise and simple structure featuring a tool support guide member, impact-reducing device, and interchangeable tool connecting means, including a tool support guide member to stabilize tool movement and an impact-reducing device to absorb and buffer abnormal impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex holder structure with many components is used, then the holder can accommodate various medical tools, but the manufacturing and maintenance costs increase and the reliability decreases
Solution Approach 1:
The holder is designed with a universal interface system that can accommodate multiple types of medical tools (reamers, impactors, cutters) through a single standardized mounting mechanism. The tool mounting hole and connecting means are configured to universally accept different tool types without requiring complex switching mechanisms, thereby achieving versatility while maintaining structural simplicity.
Solution Approach 2:
The holder structure is divided into distinct functional segments: the holder main body with tool mounting hole, the tool support guide member for movement guidance, and the tool connecting means for secure attachment. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure simple and maintainable.
2Device complexity
If the holder structure is simplified, then manufacturing and maintenance costs decrease, but the operational stability and durability may be compromised
Solution Approach 1:
The tool support guide member is pre-configured within the holder main body to provide guidance and support before the tool is fully installed and activated. This preliminary support structure ensures that tools are properly aligned and stabilized from the moment of insertion, preventing operational instability while maintaining a simple overall design.
Solution Approach 2:
The tool support guide member acts as an intermediary element between the holder main body and the medical tool. It mediates the interaction by providing movement guidance and support, ensuring operational stability without requiring the holder structure itself to be complex. The guide member absorbs the complexity of tool support functions while keeping the holder structure simple.
3Device complexity
If the holder lacks impact buffering capability, then the structure remains simple, but misaligned impacts can cause damage to the holder and impactor
Solution Approach 1:
The holder is equipped with an impact-reducing device that is pre-installed and activated before any impact occurs. This device provides cushioning and protection against misaligned impacts from the beginning, preventing damage to the holder and impactor while maintaining relatively simple structural design. The impact-reducing capability is built-in rather than added as a complex external system.

AI summary
The disclosure relates to a holder for medical tools, to which an impactor, a reamer, etc. used in a surgical operation is mounted, and more specifically, to a holder for medical tools, which has a concise and simple structure, satisfies operational stability and durability, and is usable interchangeably. The holder for medical tools includes: a medical tool including a tool shaft; a holder main body internally formed with a tool mounting hole to insert the medical tool therein; and a tool supporting means supporting the medical tool inserted in the holder main body, wherein the tool supporting means includes a tool support guide member to guide movement of the tool shaft while supporting the tool shaft.
