Robotic Arm Cart Identification for Surgical Table Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic surgical systems face challenges in aligning the robotic arm with the surgical table and verifying compatibility between the robotic arm and connected devices.
Innovation Solution
A surgical robotic system that includes a control tower and a movable robotic arm cart, where the control tower has a first connector coupled to a first controller, and the robotic arm cart has a second connector coupled to a second controller. The system uses an identification signal transmitted by the robotic arm cart to initialize its operation with the control tower, ensuring proper alignment and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robotic arm is made movable on a cart to allow repositioning in the operating room, then the adaptability and flexibility of the system is improved, but the challenge of aligning the robotic arm with the surgical table and verifying compatibility increases
Solution Approach 1:
The system performs preliminary identification and alignment actions by transmitting identification signals from the robotic arm cart to the control tower before surgical operation begins. The control tower receives and processes these signals to verify compatibility and establish proper alignment, ensuring all necessary verifications are completed in advance rather than during the procedure.
Solution Approach 2:
The system implements feedback through the transmission and processing of identification signals. The robotic arm cart transmits identification information to the control tower, which processes the signals and uses the feedback to determine compatibility and proper alignment, enabling the system to self-verify and self-adjust before operation.
2Reliability
If identification signals are transmitted through connector contacts to verify compatibility, then the reliability of device matching is improved, but the device complexity and number of required contacts increases
Solution Approach 1:
The connector contacts serve multiple functions: they provide both mechanical/electrical connection for power and data transmission, and simultaneously function as identification elements for compatibility verification. The same physical contacts that transmit electrical signals also carry identification information, eliminating the need for separate identification mechanisms.
Solution Approach 2:
The system merges the identification function with the existing connector structure. Instead of adding separate identification hardware or mechanisms, the patent combines the identification signal transmission with the standard electrical connector contacts, integrating multiple functions into a single component system.
