Implant-Specific Drill Bit with Pre-Cutting Edges for Cartilage Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical instruments for cartilage repair in joints lack precision and ease of use, leading to misplacement of implants and prolonged convalescence, with existing tools being cumbersome and requiring high skill levels.
Innovation Solution
A modular surgical kit comprising a guide base and guide body with a positioning system and drill adjustment device, along with an implant-specific drill bit, designed to facilitate precise placement of implants and debris removal during surgery, using a drill and bone remover tool with shape cutting edges and pre-cutting edges for optimal fit and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional surgical instruments are used for cartilage repair, then the surgical procedure can be performed, but precision of implant placement deteriorates and convalescence time increases
Solution Approach 1:
The surgical kit performs preliminary actions by pre-configuring the guide base, guide body, and drill bit assembly before the actual implantation. The guide body is positioned and secured to define the exact implant location, and the drill bit with integrated cutting edges is prepared in advance, eliminating the need for multiple separate steps during surgery and reducing overall procedure time and convalescence.
Solution Approach 2:
The drill bit integrates multiple functions into a single tool: it includes both central drill part for creating the pilot hole and bone remover part with shape cutting edges for forming the implant cavity. This multi-functional design eliminates the need for separate drilling and bone removal instruments, improving placement precision while reducing surgical time.
2Ease of operation
If conventional surgical tools are used, then basic cartilage repair can be performed, but ease of operation deteriorates and skill level requirements increase
Solution Approach 1:
The surgical kit is divided into distinct modular components: guide base, guide body, and drill bit assembly. Each component has a specific function and can be independently positioned and secured. This segmentation allows surgeons to assemble and adjust the system step-by-step, making it easier to operate while maintaining precision, thereby reducing the skill barrier compared to monolithic conventional tools.
3Measurement precision
If modular surgical kit is used, then precision and ease of use are improved, but device complexity increases
Solution Approach 1:
The surgical kit is divided into distinct modular components: guide base, guide body, and drill bit assembly. Each component has a specific function and can be independently positioned and secured. This segmentation allows surgeons to assemble and adjust the system step-by-step, making it easier to operate while maintaining precision, thereby reducing the skill barrier compared to monolithic conventional tools.
Solution Approach 2:
The drill bit merges the central drill part and bone remover part into a single integrated tool with both functions. This combining reduces the number of separate instruments needed, simplifying the overall device complexity despite the modular nature of the surgical kit, while maintaining high precision through the integrated design.

AI summary
A drill tool for implant surgery including a first drill part having a first, smaller diameter for drilling a recess for an implant post and a second drill part having a second, larger diameter for drilling a recess for an implant hat is disclosed. The second drill part has one or more shape cutting edges and one or more sharp pre-cutting edges extending beyond said one or more shape cutting edges.
