Surgical Guide Track for Anatomic Surface Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopaedic implantation procedures face challenges in accurately preparing anatomical surfaces, such as bones or cartilage, due to the need for precise two-dimensional surface preparation, which is often difficult to achieve with existing surgical instruments.
Innovation Solution
A surgical guide system that includes a track or path to guide a follower of a surgical instrument in two dimensions, allowing for precise preparation of anatomical surfaces by constraining the instrument's movement and eliminating the need for complex manual replication of surface patterns, using a guide with a top portion that prevents axial movement and a bottom portion with a track that matches the desired surface shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional surgical instruments are used for surface preparation, then the surgical procedure can be performed, but the precision and accuracy of two-dimensional surface preparation deteriorates
Solution Approach 1:
The patent introduces a guide with a track as an intermediary device between the surgeon's manual control and the surgical instrument. The track physically guides the follower along a predetermined path, mediating the movement to ensure precise two-dimensional surface preparation without requiring complex manual control techniques from the surgeon.
Solution Approach 2:
The guide and track are designed and positioned before the actual surface preparation occurs. The predetermined path is established in advance, allowing the surgical instrument to follow an optimized trajectory that ensures precision without requiring real-time complex control decisions during the procedure.
2Manufacturing precision
If complex manual techniques are used to achieve precise surface preparation, then the desired surface shape can be prepared, but the device complexity and procedural difficulty increases
Solution Approach 1:
The guide replicates or copies the desired surface geometry into a physical track structure. By creating a tangible model of the target surface shape in the form of a guided path, the system eliminates the need for complex real-time control techniques, as the track itself embodies the precise geometric information needed for accurate surface preparation.
3Productivity
If manual control is used without guidance, then the surgical instrument can be maneuvered freely, but the time and precision required for accurate surface preparation increases
Solution Approach 1:
The track serves as a physical intermediary that simultaneously provides both guidance for precision and a predetermined path for efficiency. The follower constrained to move along the track achieves accurate positioning automatically, eliminating the trade-off between free maneuverability and precision while streamlining the preparation process.
