Surgical Reamer Quick-Disconnect Coupling for Faster Tool Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic surgical reaming systems face challenges with lengthy procedure times due to the time-consuming process of changing cutting heads and tools during joint replacement surgeries, particularly in robotic joint replacement procedures like shoulder and hip arthroplasties.
Innovation Solution
A reaming system with a quick disconnect mechanism featuring a reaming retainer and reamer support that allows for rapid locking and unlocking of cutting heads, reducing interference with patient tissue and minimizing procedure duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional reaming systems are used with fixed cutting heads, then structural stability is maintained, but procedure time increases due to time-consuming tool changes
Solution Approach 1:
The reaming system is divided into modular components including a reamer with a cutting head that can be independently attached and detached from the reaming guide. This segmentation allows rapid tool changes without affecting the overall system structure, directly reducing procedure time while maintaining manageable complexity through standardized interfaces
Solution Approach 2:
The system transitions from a fixed, static configuration to a dynamic, adaptable configuration where the cutting head can be quickly exchanged during the procedure. The quick-connect mechanism enables the system to adapt its tooling dynamically based on surgical needs, reducing downtime between tool changes while preserving structural stability through robust mounting interfaces
2Adaptability or versatility
If cutting heads are frequently changed during surgery, then adaptability is improved, but procedure time increases due to repeated tool changes
Solution Approach 1:
Multiple cutting heads with different specifications are pre-prepared and sterilized before surgery. The quick-connect mechanism allows these pre-prepared tools to be rapidly exchanged during the procedure without requiring complex setup or adjustment, thereby maintaining high adaptability while minimizing the time penalty associated with tool changes
Solution Approach 2:
The reaming guide is designed with a universal quick-connect interface that can accommodate various types of cutting heads and tools. This universal design enables frequent tool changes across different surgical scenarios without requiring multiple specialized mounting mechanisms, thus improving adaptability while reducing the cumulative time loss from tool changes

AI summary
An reaming system can be connectable to a robotic surgical system including an end effector of a robotic arm. The reaming system can include a reaming guide and a reamer. The reaming guide can include a body releasably couplable to the end effector at a proximal portion of the body and a housing located at a distal portion of the body. The reamer can be operable to ream bone. The reamer can include a support releasably couplable to the housing to secure the reamer to the reaming guide and the end effector. The reamer can include a cutting head connected to the support, the cutting head rotatable with respect to the housing when the support is coupled to the housing.
