Kirschner Wire Clamp With Guide Element For Bone Plate Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Kirschner wire clamps are difficult to handle and provide limited functionality, requiring more time and space for use in stabilizing bone fragments before final healing, making it challenging to achieve precise and reliable positioning of bone plates.
Innovation Solution
A Kirschner wire clamp design featuring a guide element, base element, and clamping element, where the base element is positioned at one end of the guide element, allowing for precise alignment and fixation of the bone plate, with a clamping region that securely engages the Kirschner wire, enabling easy and quick positioning of the bone plate on the bone surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional Kirschner wire clamps are used, then the bone plate can be temporarily attached, but the clamp is difficult to handle and requires more time and space for use
Solution Approach 1:
The clamp is divided into three distinct functional elements: a guide element for alignment, a base element for positioning, and a clamping element for securing. This segmentation allows each component to perform its specific function efficiently, improving overall ease of operation and reducing the time required for bone plate positioning.
Solution Approach 2:
The guide element acts as an intermediary between the operator and the bone plate, providing alignment guidance. The base element serves as an intermediary for positioning the plate on the bone surface. These intermediary elements simplify the handling process and reduce the time needed for accurate positioning.
2Measurement precision
If traditional Kirschner wire clamps are used, then the bone plate can be positioned, but the alignment precision is insufficient
Solution Approach 1:
The clamp is divided into three distinct functional elements: a guide element for alignment, a base element for positioning, and a clamping element for securing. This segmentation allows each component to perform its specific function efficiently, improving overall ease of operation and reducing the time required for bone plate positioning.
Solution Approach 2:
The guide element acts as an intermediary between the operator and the bone plate, providing alignment guidance. The base element serves as an intermediary for positioning the plate on the bone surface. These intermediary elements simplify the handling process and reduce the time needed for accurate positioning.
3Reliability
If traditional Kirschner wire clamps are used, then the bone plate can be fixed, but the clamping element requires too much space
Solution Approach 1:
The clamp is divided into three distinct functional elements: a guide element for alignment, a base element for positioning, and a clamping element for securing. This segmentation allows each component to perform its specific function efficiently, improving overall ease of operation and reducing the time required for bone plate positioning.
Solution Approach 2:
The clamping element is designed with localized functionality, concentrating the clamping force in a specific region rather than requiring extensive space. This local quality approach maintains reliable fixation while minimizing the overall space requirement of the clamp.

AI summary
A Kirschner wire clamp is used to reliably and simply fix bone plates to a bone surface. The wire clamp consists of a tubular guide member for receiving a Kirschner wire. The guide member has a bore surrounded by a wall and a base for engaging a hole in a bone plate such as a bone screw hole. A spring clamp is mounted adjacent an open end of the tubular guide bore opposite the base which clamps the Kirschner wire to the guide member after the wire has been fixed in bone. The Kirschner wire clamp can be aligned simply and reliably by the guide member, and by the clamping mechanism, can be reliably fixed to the Kirschner wire.
