Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical robotic systems are complex, costly, and bulky, limiting their affordability and accessibility in surgical departments. They also pose challenges in maintaining sterility and can impede the surgeon's ability to quickly access the surgical site.
Innovation Solution
A remotely actuated surgical robot system with robotic telemanipulators that are designed to be adaptable, cost-effective, and integrated seamlessly into the operating room. The system includes a master console with removable, sterilizable handles and a slave console with a rotatable distal end for easy access, allowing for sterile operation and efficient laparoscopic procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional robotic surgical systems are used, then surgical precision and dexterity are improved, but system complexity and cost increase significantly
Solution Approach 1:
The robotic system is divided into separate functional modules: a master console for surgeon control, a slave console for instrument manipulation, and removable handles for sterilization. This segmentation allows each component to be optimized independently while reducing overall system complexity and cost.
Solution Approach 2:
The master and slave consoles are designed with universal interfaces that can accommodate multiple instrument types and surgical procedures. The rotatable distal end of the slave console provides multi-directional access capability, making the system versatile for various surgical applications without requiring multiple specialized robots.
2Manufacturing precision
If traditional robotic surgical systems are used, then surgical precision is improved, but affordability and accessibility decrease
Solution Approach 1:
The handles are designed as removable and sterilizable components rather than disposable items. This approach reduces long-term costs by allowing repeated use after sterilization, while maintaining the precision and performance of the robotic system. The modular design enables cost-effective manufacturing of individual components.
3Extent of automation
If traditional robotic surgical systems are used, then remote surgical capability is improved, but sterility maintenance becomes difficult
Solution Approach 1:
The system separates sterile and non-sterile zones through removable handles that can be sterilized independently. The master console remains outside the sterile field while the slave console and instruments can be sterilized, maintaining sterility reliability while enabling remote surgical capability.
4Manufacturing precision
If traditional robotic surgical systems are used, then surgical precision is improved, but space requirements and preparation time increase
Solution Approach 1:
The slave console components are designed to nest within each other when not in use, with the distal end rotating to compact positions. This nesting capability reduces the space footprint of the robotic system in the operating room while maintaining full surgical precision capability during procedures.

AI summary
Surgical robot systems for remote manipulation having robotic telemanipulators are provided. The surgical robot systems are well adapted for use by the surgeon, seamlessly integrateable into the operation room, allow for a surgeon to work between the robot and the patient throughout a surgery in a sterile manner, are relatively low cost, and/or permit integrated laparoscopy. The system preferably includes a master console having a plurality of master links interconnected by a plurality of master joints, and a handle coupled to the master console for operating the telemanipulator. The system further includes a slave console operatively coupled to the master console and having a plurality of slave links interconnected by a plurality of slave joints that move responsive to movement at the master console to permit an end-effector to perform surgery.
