Surgical Robot Sleeve Assembly for Cutter Swaps and Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical robot cutting devices face challenges in compatibility and accuracy during artificial joint surgery due to the need for individually manufactured sleeves when changing cutter lengths or diameters, and difficulty in installing calibration tools.
Innovation Solution
A calibration mounting part-equipped surgical device with a sleeve having a large outer diameter and interchangeable compatibility, featuring a chuck device part, holder part, and detachable calibration mounting part, including a holding cap member and calibration shaft with a position-setting member, to facilitate easy installation and accurate calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional sleeve is used with fixed dimensions, then the structure is simple, but it cannot accommodate cutters of different lengths or diameters, reducing adaptability
Solution Approach 1:
The sleeve incorporates a movable outer diameter adjustment mechanism that allows dynamic changing of the sleeve's outer diameter to match different cutter sizes. The adjustment mechanism includes movable adjustment members that can be positioned at different locations on the sleeve body, enabling the sleeve to adapt from a small outer diameter state to a large outer diameter state, thus accommodating cutters with different dimensions without requiring multiple fixed-dimension sleeves.
2Adaptability or versatility
If individually manufactured sleeves are used for different cutters, then cutter compatibility is achieved, but manufacturing costs increase and preparation becomes difficult
Solution Approach 1:
The sleeve is designed as a universal component that can accommodate multiple types of cutters with different dimensions through its adjustable outer diameter mechanism. Instead of manufacturing separate sleeves for each cutter type, a single sleeve with adjustment capabilities serves multiple functions, reducing the number of unique components needed and simplifying preparation procedures.
Solution Approach 2:
The sleeve structure is divided into functional segments including the sleeve body, adjustment members, and locking mechanisms. This segmentation allows the adjustment members to be independently positioned and secured at different locations, enabling flexible adaptation to various cutter sizes while maintaining a standardized base sleeve design that can be manufactured efficiently.
3Measurement precision
If calibration tools are installed in conventional cutting devices, then calibration can be performed, but the installation process is complex and positioning accuracy is difficult to ensure
Solution Approach 1:
The sleeve includes pre-formed calibration tool installation holes that are positioned at predetermined locations and orientations. These holes are prepared in advance during sleeve manufacturing, allowing calibration tools to be directly installed without requiring complex alignment procedures. The pre-positioned holes ensure accurate calibration tool placement relative to the cutter axis, simplifying the installation process while maintaining high positioning accuracy.
