Peripheral Peg Drill Component Simultaneous Drilling
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 a housing and at least two drill bits that can be advanced over an alignment pin and actuated by a belt and pulley system to simultaneously drill multiple holes in the bony surface, reducing the need for individual hole drilling and improving alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple pre-drilled holes are created for peripheral pegs using individual drilling, then secure attachment of glenoid component is achieved, but surgical time and complexity increase significantly
Solution Approach 1:
The patent combines multiple individual drilling operations into a single simultaneous drilling operation using a drill guide with multiple drill bits positioned at predetermined locations. This merging of operations maintains the secure attachment reliability while dramatically reducing surgical time by eliminating sequential drilling steps.
Solution Approach 2:
The drill guide is pre-configured with multiple drill bits positioned at the exact locations where peripheral peg holes need to be drilled. This preliminary positioning of drilling elements eliminates the need for repeated measurement and alignment during surgery, reducing surgical time while ensuring accurate hole placement for secure component attachment.
2Manufacturing precision
If multiple pre-drilled holes are created for peripheral pegs using individual drilling, then complete bone preparation is achieved, but drilling misalignment risk increases
Solution Approach 1:
By merging multiple drilling operations into a single simultaneous operation through a multi-bit drill guide, the patent eliminates cumulative alignment errors that occur with sequential drilling. All holes are drilled in one positioning action, improving drilling alignment precision while reducing the complexity of repeated alignment procedures.
Solution Approach 2:
The drill guide serves as an intermediary device that pre-establishes the correct spatial relationships between multiple drill bit positions. This intermediary tool translates the complex requirement of multiple precisely aligned holes into a single positioning action, improving alignment accuracy while simplifying the bone preparation process.
3Reliability
If up to five peripheral pegs are used to stabilize glenoid component, then secure articulating surface is achieved, but number of drilling operations increases
Solution Approach 1:
The patent merges the drilling operations for up to five peripheral peg holes into a single simultaneous drilling operation using a drill guide with multiple positioned drill bits. This maintains the stability provided by multiple peripheral pegs while dramatically improving bone preparation efficiency by reducing five separate operations to one.

AI summary
A method for simultaneously drilling at least two peripheral peg holes in a bony surface 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; 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 belt circumferentially surrounding a series of pulleys 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.
