Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical tools and procedures for securing damaged skeletal tissue or soft tissue are time-consuming and complex, requiring multiple steps that are difficult to perform effectively for fracture reduction, fracture fixation, and crack propagation prevention.
Innovation Solution
An apparatus and method using a hole-forming tool to create a pass-through hole in bone, allowing a cable to be easily passed through and tensioned for secure fracture reduction and fixation, which includes a shank, cutting portion, and connection features for efficient coupling with a driving tool and cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tools and procedures are used for securing damaged skeletal tissue, then the tissue can be secured, but the procedure becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple functions into a single integrated tool. The hole-forming tool includes both cutting portions for creating the tunnel and connection features for attaching the cable, eliminating the need for separate drilling and cable-passing steps. This merging of functions directly reduces procedure time while maintaining reliable tissue securing.
Solution Approach 2:
The hole-forming tool is designed with multi-functionality, serving as both a drilling instrument and a cable delivery mechanism. The tool can form pass-through holes in bone and simultaneously pass cables through these holes, making it a universal tool that replaces multiple specialized instruments, thereby reducing overall procedure time and complexity.
2Reliability
If conventional tools and procedures are used for securing damaged skeletal tissue, then the tissue can be secured, but the procedure becomes complex with multiple steps
Solution Approach 1:
The patent merges hole formation and cable passage into a single integrated operation. The hole-forming tool creates the tunnel and has built-in connection features that allow direct attachment and passage of the cable, reducing the number of discrete steps and instruments needed while ensuring reliable tissue securing.
Solution Approach 2:
The hole-forming tool is designed to perform multiple functions autonomously. After forming the hole, the tool itself provides the connection features necessary for cable attachment and passage without requiring additional instruments or complex manipulation, thereby simplifying the overall procedure while maintaining effectiveness.
3Device complexity
If a single cutting portion is used in the hole-forming tool, then the structure is simpler, but the cable passage through bone is less efficient
Solution Approach 1:
The cutting portion is segmented into multiple distinct cutting elements (first cutting portion and second cutting portion) with different diameters. This segmentation allows the tool to efficiently create pass-through holes of varying sizes and shapes in bone, improving cable passage efficiency while maintaining a relatively simple overall tool structure through modular design.

AI summary
An apparatus for passing a cable through a pass-through hole in a bone that includes a hole-forming tool and a cable. The hole-forming tool has a shank, a cutting portion, and a first connection feature. The cutting portion is interposed between the shank and the first connection feature and the shank is detachably coupleable to a driving tool. The cable has a first-end portion that has a second connection feature. The cable is detachably coupleable to the hole-forming tool via the first connection feature of the hole-forming tool and the second connection feature of the first-end portion of the cable.
