Surgical Reaming Guide With Quick-Disconnect Reamer Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic joint replacement procedures, such as shoulder and hip arthroplasties, face inefficiencies due to the time-consuming process of changing cutting heads and tools during reaming operations, which can interfere with tissue and prolong surgical procedures.
Innovation Solution
A reaming system with a quick disconnect mechanism, featuring a reaming retainer and a curved or non-linear design to minimize tissue interference, allows for rapid locking and unlocking of the reamer, enabling quicker tool changes and reducing procedure duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional tool changing methods are used during reaming operations, then the reaming can be performed, but the procedure time is prolonged and tissue interference occurs
Solution Approach 1:
The reaming system is divided into modular components including a reusable reaming guide and interchangeable reamers with different cutting heads. This segmentation allows the cutting head to be quickly swapped without replacing the entire reaming system, enabling rapid tool changes during the procedure.
Solution Approach 2:
The system incorporates a dynamic quick-change mechanism that allows the reamer to be rapidly exchanged during the procedure. The reusable reaming guide remains in place while only the reamer component is changed, providing flexibility and reducing downtime between tool changes.
2Productivity
If traditional tool changing methods are used during reaming operations, then the reaming can be performed, but tissue interference is caused
Solution Approach 1:
By separating the reaming guide from the reamer, the system allows tool changes to occur with minimal movement and repositioning. The guide remains stable in the bone while only the reamer is exchanged, reducing the risk of tissue disruption during tool changes.
Solution Approach 2:
The reaming guide is pre-positioned and secured in the bone before the procedure begins. This preliminary action establishes a stable reference framework that remains in place throughout the procedure, allowing multiple reamers to be exchanged without requiring repositioning or causing additional tissue interference.

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.
