Dual Tip Guide Wire for Bone Piercing and Boring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tools for minimally invasive procedures require multiple instruments and incisions, increasing the risk of infection and complexity in surgeries involving bone manipulation, particularly in long bones with intramedullary canals.
Innovation Solution
A dual-tip guide wire with a sharpened end for piercing and a spade-like end for boring, allowing for both functions without removing the tool from the surgical site, reducing the need for multiple instruments and incisions, featuring a robust and cost-effective design with a laser-welded attachment member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple surgical instruments are used for bone piercing and boring, then the functionality is improved, but the device complexity and number of incisions increase
Solution Approach 1:
The patent combines two separate surgical instruments (piercing instrument and boring instrument) into a single dual-tip guide wire. The first end features a sharpened tip for piercing bone, while the second end features a spade tip with flutes for boring bone. This merging eliminates the need for multiple instruments and reduces the number of incisions required during surgery.
Solution Approach 2:
The guide wire is designed as a universal tool that can perform multiple functions: it can pierce bone with the sharpened tip, bore bone with the spade tip, and can be used bidirectionally (inserted from either end depending on surgical needs). This multi-functionality replaces the need for multiple specialized instruments while maintaining adaptability to different surgical scenarios.
2Adaptability or versatility
If multiple surgical instruments and incisions are used, then the surgical capability is improved, but the risk of infection and cross-contamination increases
Solution Approach 1:
By merging piercing and boring functions into a single guide wire, the patent reduces the number of times instruments need to be inserted and removed from the surgical site. This reduction in instrument traffic through incisions directly lowers the risk of introducing pathogens and causes of cross-contamination.
Solution Approach 2:
The multi-functional guide wire allows surgeons to perform multiple bone preparation tasks through a single incision or minimal incisions, thereby reducing the exposure of internal tissues to potential contaminants that would occur with multiple separate instrument insertions.
3Adaptability or versatility
If multiple tools are used for bone preparation, then the surgical options are improved, but the procedural complexity and time increase
Solution Approach 1:
The patent merges piercing and boring capabilities into one instrument, allowing surgeons to switch between functions by simply rotating or repositioning the guide wire rather than removing and replacing instruments. This eliminates the time lost in instrument changes while preserving all necessary bone preparation techniques.
Solution Approach 2:
The dual-tip guide wire provides universal bone preparation capability that allows surgeons to adapt their technique mid-procedure without instrument changes. The sharpened tip can pierce when needed, and the spade tip can bore when needed, all within a single continuous procedure, thereby reducing overall surgical time.
4Adaptability or versatility
If multiple instruments are inserted into the body, then the surgical functionality is improved, but the chance for lost articles and cross-contamination increases
Solution Approach 1:
By combining multiple functions into a single guide wire instrument, the patent reduces the total number of separate instruments that could potentially be lost or misplaced during surgery. There is only one guide wire to track and manage, improving reliability and reducing the risk of retained foreign objects.
