Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If doctors wear lead protective clothing to protect against radiation, then radiation protection is improved, but the weight and body load increase, affecting surgical operation
Solution Approach 1:
The patent replaces manual mechanical operations with an automated robotic system that has independent driving capabilities. The slave-side execution apparatus can autonomously convey guidewires and catheters through powered driving devices, eliminating the need for doctors to perform manual manipulation while wearing heavy protective gear.
Solution Approach 2:
The robotic system acts as an intermediary between the control operator and the surgical field. The slave-side execution apparatus receives control signals and autonomously performs the conveyance operations, serving as a mediator that eliminates direct human exposure to radiation while maintaining surgical precision.
2Ease of operation
If manual operation by experience and feeling is used for complex implant intervention surgeries, then surgical flexibility is improved, but the difficulty and risk of surgery increase
Solution Approach 1:
The system incorporates feedback mechanisms where control operators can monitor the real-time status of guidewire and catheter conveyance and adjust control signals accordingly. The robotic system provides tactile and visual feedback to maintain surgical flexibility while reducing risk through automated precision control.
Solution Approach 2:
The slave-side execution apparatus has autonomous capabilities to independently convey guidewires and catheters through its own driving devices, without requiring constant manual intervention. This self-service capability reduces surgical risk by maintaining stable, controlled operations while preserving flexibility through operator oversight.
3Power
If active components with power sources are used in the slave-side execution apparatus, then driving capability is improved, but the risk of infection and installation complexity increase
Solution Approach 1:
The patent extracts the power source and active driving components from the slave-side execution apparatus and relocates them to the master control side. The slave-side components become passive, consisting only of transmission mechanisms that convey guidewires and catheters without embedded power sources, thereby eliminating infection risks and simplifying installation.

AI summary
A slave-side execution apparatus and a medical system are provided. The slave-side execution apparatus is used to convey a guidewire and/or a catheter, and includes a main body power device, a movable power device, a first carrying device and a first manipulation device. The main body power device includes a main body driving device. The movable power device includes a first driving device and is used to move forward and backward along a conveying direction under the driving of the main body driving device. The first carrying device is moved synchronously with the movable power device and is used to carry a medical apparatus having a catheter. The first manipulation device is disposed on the first carrying device, and is used to control the guidewire to move forward and backward along the conveying direction under the driving of the first driving device.
