Universal Surgical Robot Sleeve for Interchangeable Cutters and Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical robot cutting devices face challenges with compatibility issues due to the need for individually manufactured sleeves when changing cutter lengths or diameters, leading to increased costs and difficulty in installing and calibrating calibration tools accurately.
Innovation Solution
A calibration mounting part-equipped surgical device featuring a sleeve with a hollow body and interchangeable design, including a chuck device part, holder part, and detachable calibration mounting part, which supports various medical tools and allows easy installation of calibration tools through a fastening method and rotation blocking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individually manufactured sleeves are used for different cutter specifications, then compatibility with various cutters is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements a universal sleeve structure that can accommodate multiple cutter types (different lengths and diameters) through a standardized interface design. The sleeve includes a standardized mounting portion that interfaces with various cutters, allowing one sleeve design to serve multiple functions across different surgical procedures and cutter specifications.
Solution Approach 2:
The sleeve is divided into functional segments: a standardized mounting portion for cutter attachment and a support portion for structural stability. This segmentation allows the mounting interface to remain consistent while accommodating variations in cutter dimensions, reducing the need for completely different sleeve designs for each cutter type.
2Adaptability or versatility
If individually manufactured sleeves are used for different cutter specifications, then compatibility with various cutters is improved, but manufacturing costs increase
Solution Approach 1:
By designing a universal sleeve that can accommodate multiple cutter types through standardized interfaces, the system reduces the total number of unique components that need to be manufactured. This standardization enables economies of scale in production and reduces inventory complexity.
3Device complexity
If conventional sleeve design is used, then simple structure is maintained, but calibration tool installation and positioning accuracy deteriorate
Solution Approach 1:
The sleeve includes pre-formed calibration tool mounting features and positioning structures that are integrated into the basic sleeve design. These features are prepared in advance during manufacturing, enabling accurate calibration tool installation without requiring complex assembly steps or additional adjustment procedures.
4Ease of manufacture
If conventional sleeve design is used, then manufacturing simplicity is maintained, but calibration tool movement control deteriorates
Solution Approach 1:
The sleeve incorporates pre-designed constraint structures such as positioning grooves, locking features, or friction-fit interfaces that are built into the manufacturing process. These features automatically constrain calibration tool movement when installed, providing stable positioning without requiring complex additional mechanisms.
