Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopedic surgical procedures lack precise quantitative measurement data, relying heavily on subjective surgeon skills, which can lead to variations in patient outcomes due to individual anatomical differences, and there is a need for real-time feedback and monitoring of musculoskeletal system parameters during and after surgery.
Innovation Solution
The development of a kinetic orthopedic measurement system that includes smart screws and sensors integrated with electronic circuitry, capable of measuring and transmitting real-time data on parameters like alignment, load, and motion, providing quantitative feedback for improved surgical precision and post-operative monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional orthopedic surgical procedures are used, then the procedure can be performed with standard tools, but the measurement precision and quantitative data collection are insufficient
Solution Approach 1:
The patent replaces traditional mechanical measurement tools with electronic sensors and digital measurement systems. Sensors are integrated into orthopedic implants and surgical tools to electronically capture and transmit quantitative data about bone position, implant alignment, and surgical parameters, substituting mechanical measurement methods with electronic detection systems.
Solution Approach 2:
The patent introduces intermediate measurement devices and sensor systems that act as mediators between the surgical procedure and the surgeon. These intermediaries include sensors embedded in implants, wireless communication modules, and data processing systems that translate physical surgical parameters into quantifiable digital information for real-time feedback.
2Reliability
If subjective surgeon skills are relied upon, then the procedure can be performed without additional equipment, but the reliability and consistency of surgical outcomes vary
Solution Approach 1:
The patent implements real-time feedback systems where sensors continuously monitor surgical parameters such as bone alignment, implant positioning, and joint kinematics. This data is processed and presented to the surgeon during the procedure, enabling immediate adjustments to improve surgical reliability and consistency across different patients and surgeons.
Solution Approach 2:
The patent substitutes subjective surgeon assessment with objective electronic measurement and data analysis systems. Digital models, pre-operative planning software, and intra-operative navigation systems replace reliance on surgeon experience and manual measurement techniques, providing standardized, quantifiable guidance for surgical decision-making.
3Productivity
If real-time monitoring is implemented, then continuous data on musculoskeletal parameters can be obtained, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent employs universal sensor platforms and multi-functional measurement systems that can detect multiple surgical and post-operative parameters simultaneously. A single integrated system monitors bone alignment, implant stability, joint range of motion, and loading forces, reducing the need for separate specialized devices while providing comprehensive real-time data.
Solution Approach 2:
The patent introduces intermediate data processing layers including wireless communication modules, portable data collectors, and cloud-based analysis platforms that manage the complexity of real-time monitoring. These intermediaries handle data transmission, storage, and preliminary analysis, allowing continuous monitoring without overwhelming the surgical workflow or requiring complex local processing.
