ERCP Surgical Robot Remote Operation to Reduce Radiation Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
ERCP surgeries expose operators to long-term radiation due to the use of X-rays, and the manual operation leads to hand shaking and reduced accuracy due to the need for multiple operators in a confined space, causing potential errors.
Innovation Solution
An ERCP surgical robot system with an operating table, endoscopic actuation and accessory operation devices, a console, and a remote control mechanism using an EtherCAT bus, allowing doctors to operate from outside the operating room, reducing radiation exposure and hand shaking through automated control of instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation is used for ERCP surgery, then the surgeon can directly control the instruments, but the surgeon is exposed to long-term radiation and experiences hand shaking which reduces surgical accuracy
Solution Approach 1:
The patent introduces a robotic system as an intermediary between the surgeon and the surgical instruments. The surgeon operates the robotic arm from a remote control station, which manipulates the endoscope and surgical tools through a mechanical transmission system. This intermediary robotic mechanism allows the surgeon to perform precise surgical operations without direct hand manipulation inside the radiation field, thereby eliminating radiation exposure while maintaining surgical accuracy through the robotic system's stable and shake-free operation.
2Reliability
If multiple operators and collaborators are present in the operating room, then the surgery can be performed with proper assistance, but the limited space becomes congested and work intensity increases
Solution Approach 1:
The patent replaces the mechanical system of multiple human operators physically present in the operating room with an automated robotic system controlled from a remote station. The robotic arm autonomously performs instrument manipulation and positioning tasks that previously required multiple assistants. This substitution eliminates the need for multiple personnel in the confined surgical space, reducing congestion and work intensity while maintaining reliable surgical support through the robotic system's automated functions.
3Manufacturing precision
If the forceps lifter is directly adjusted by the operator, then the instrument positioning can be controlled, but the operator is exposed to X-rays and hand shaking causes positioning errors
Solution Approach 1:
The patent introduces a robotic transmission system as an intermediary between the control station and the forceps lifter mechanism. The surgeon issues positioning commands from a remote control station, and the robotic arm executes these commands to adjust the forceps lifter position. This intermediary robotic system eliminates direct operator exposure to X-rays while providing stable, shake-free positioning control through the robotic system's precision mechanics, thereby improving both operator safety and positioning precision.

AI summary
An operating system for an endoscopic retrograde cholangiopancreatography (ERCP) surgical robot includes: an operating table, where a patient lies on the operating table; an endoscopic actuation end device; an endoscopic accessory operation end device; a console, including an operating handle, a foot switch, and a three-dimensional (3D) handle; and a display screen for human-computer interaction. A forceps lifter control module, a knob control module, a catheter drive module and a water vapor suction control module on the endoscopic actuation end device are controlled through the operating handle, the foot switch, the 3D handle and the touch screen on the console. A guide wire drive module on the endoscopic accessory operation end device remotely controls the insertion and feeding of a guide wire or catheter to complete the surgery. The operating system reduces the harm caused by long-term surgical radiation to operators and avoids hand shaking of doctors during operation.
