Peripheral Peg Drill Component Simultaneous Bone Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glenoid replacement surgical techniques are time-consuming and prone to drilling misalignment due to the need for multiple pre-drilled holes for peripheral pegs, which increases the complexity of bone preparation.
Innovation Solution
A peripheral peg drill component with at least two drill bits extending from its housing, allowing simultaneous drilling into a bony surface when aligned with a guide pin, reducing the need for individual hole drilling and enhancing alignment precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple holes are drilled separately for peripheral pegs, then each hole can be individually prepared, but the process becomes time-consuming and increases the risk of drilling misalignment
Solution Approach 1:
The patent combines multiple separate drilling operations into a single integrated drilling device that creates multiple peripheral peg holes simultaneously. The housing contains multiple drill bits positioned at predetermined locations, allowing all holes to be drilled in one operation rather than sequentially, thereby reducing both time and alignment errors
Solution Approach 2:
The drill bits are pre-positioned within the housing at predetermined locations and orientations before the drilling operation begins. This preliminary positioning ensures that when the device is placed on the glenoid, all drill bits are already aligned correctly, eliminating the need for sequential alignment adjustments during the drilling process
2Ease of manufacture
If multiple holes are drilled separately for peripheral pegs, then individual hole preparation is possible, but the process complexity increases
Solution Approach 1:
The patent merges multiple drilling functions into a single device unit. The housing integrates multiple drill bits, positioning mechanisms, and activation features into one component that performs the function of what would otherwise require multiple separate drilling operations and positioning steps
Solution Approach 2:
The drilling device serves multiple functions simultaneously: it positions multiple drill bits at correct locations, orients them at proper angles, and activates them all at the same time. This multi-functionality consolidates what would otherwise be multiple separate tools or operations into a single universal device
3Reliability
If up to five peripheral pegs are used to stabilize the glenoid component, then secure articulating surface is achieved, but the number of pre-drilled holes and preparation steps increases
Solution Approach 1:
The patent provides a drilling device that creates holes for multiple peripheral pegs (up to five) in a single operation. The housing contains multiple drill bits that can simultaneously create all necessary holes for the pegs, eliminating the need for multiple separate drilling operations and reducing preparation complexity while maintaining the stability provided by multiple pegs

AI summary
A method for simultaneously drilling at least two peripheral peg holes in a bony surface, the method comprising providing a peripheral peg drill component including a housing with a first side, a second side opposite the first side and at least two drill bits extending from the second side of the housing; releasably coupling the first side of the peripheral peg drill component to a drilling device; advancing the peripheral peg drill component over an alignment pin extending from a bony surface until each of the at least two drill bits engage the bony surface; actuating a driving mechanism of the peripheral peg drill component with the drilling device to cause the at least two drill bits to rotate; and simultaneously penetrating the bony surface with the at least two drill bits as they rotate.
