Operator-Side Surgical Control Wiring via Serial Substrate Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing robotic surgical systems require a large number of wire lines to connect sensors and operation buttons to the controller, leading to thick, heavy, and bulky structures that hinder miniaturization.
Innovation Solution
The proposed solution involves a robotic surgical system with a surgical instrument operation unit that includes a first substrate to which signals are input, and a controller connected to this substrate via serial communication using a single wire line, thereby reducing the number of wire lines needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wire lines are used to connect each sensor and operation button directly to the controller, then signal transmission reliability is improved, but the number of wire lines increases making the structure thick and heavy
Solution Approach 1:
The patent combines multiple signal lines into a single bundled wire line by implementing a substrate structure that integrates multiple sensors and operation buttons. This merging approach maintains signal transmission reliability while significantly reducing the number of separate wire lines, thereby decreasing the weight and size of the operation unit.
Solution Approach 2:
The substrate serves multiple functions simultaneously: it provides mechanical support for sensors and operation buttons, acts as a signal transmission medium, and enables integrated wiring. This multi-functionality eliminates the need for separate connection structures for each sensor, reducing overall wire line count and operational unit weight.
2Reliability
If multiple separate wire lines are used for each sensor and operation button, then signal integrity is maintained, but the structure becomes bulky affecting miniaturization
Solution Approach 1:
Multiple signal transmission functions are merged into a single bundled wire line structure. The substrate integrates multiple sensors and operation buttons, allowing their signals to be transmitted through one consolidated wire line rather than multiple separate lines, thereby reducing the volume of the operation unit.
Solution Approach 2:
The patent employs a nested structure where multiple wire lines are bundled together within a single outer insulation layer. This nesting approach allows multiple signal transmission paths to coexist in a compact arrangement, maintaining signal integrity while minimizing the space required for wiring.
3Volume of moving object
If the number of wire lines is reduced by using a substrate, then miniaturization is achieved, but the length of individual wire lines may increase
Solution Approach 1:
The substrate is designed with pre-arranged signal transmission paths that optimize wire line routing. By planning the signal routes in advance during substrate design, the patent minimizes the length of wire lines while achieving miniaturization, preventing excessive wire line length from becoming a problem.
Solution Approach 2:
The substrate provides localized signal transmission optimization by routing wire lines through the most efficient paths for each specific sensor and operation button. This localized optimization ensures that while the overall structure is miniaturized, individual wire line lengths are kept as short as possible for each connection.
