Integrated Surgical Device Minimizing Setup Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image guided surgery systems require large, separate devices that occupy significant space in the operating theater, necessitate complex setup, and disrupt the surgeon's line of sight, as they need to be arranged to ensure proper functioning and visibility while also providing navigational assistance.
Innovation Solution
An integrated, portable unit combining the surgical instrument, tracking system, and medical navigation system, where the tracking sensor and display are integrated within a single, handheld device, allowing for easy setup and use, with the display located near the instrument to maintain focus on the surgical site and reduce setup complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate devices are used for surgical instrument, tracking system, and navigation system, then each component can be optimized independently, but the system occupies significant space and requires complex setup
Solution Approach 1:
The patent combines the surgical instrument, tracking system with sensor, and navigation system with display into a single integrated portable unit. This merging eliminates the need for separate devices and complex setup procedures while maintaining all necessary functions. The integrated design allows the system to be easily transported between operating theaters and deployed without extensive configuration.
Solution Approach 2:
The portable unit serves multiple functions simultaneously: it acts as a surgical instrument, contains tracking sensors for locating objects, processes navigation data, and provides visual feedback through a display. This multi-functionality replaces what previously required multiple separate devices, simplifying the overall system while maintaining independent optimization capabilities through modular internal design.
2Reliability
If large separate devices are used, then navigation and tracking functions can be provided, but they disrupt the surgeon's line of sight and require special arrangement
Solution Approach 1:
The display is positioned in a location that does not obstruct the surgeon's view of the surgical site, utilizing spatial arrangement in multiple dimensions. The portable unit can be placed at an angle or position where the display faces the surgeon from the side or above, allowing simultaneous viewing of both the surgical field and navigation information without blocking the primary line of sight.
Solution Approach 2:
The integrated portable unit serves as an intermediary device that brings navigation and tracking information directly to the surgical field without requiring separate large equipment. The compact display and sensor system mediate between the surgical instrument and the navigation system, providing real-time feedback in a space-efficient manner that does not interfere with the surgeon's workflow or visibility.
3Adaptability or versatility
If multiple separate components are used, then each can perform its specific function, but the system requires significant space and special arrangement in the operating theater
Solution Approach 1:
The patent integrates the surgical instrument, tracking system with sensor, and navigation system with display into a single portable unit, dramatically reducing the space required in the operating theater. This merging maintains all necessary component functionalities while consolidating them into a compact form factor that can be easily positioned without requiring extensive spatial arrangement.
4Reliability
If separate devices are used, then each component can be optimized for its specific task, but setup and arrangement require significant time and effort
Solution Approach 1:
The system components are pre-integrated into a single portable unit during manufacturing, eliminating the need for time-consuming setup and arrangement procedures in the operating theater. The pre-assembled unit requires minimal configuration upon deployment, significantly reducing setup time while maintaining the performance optimization of each internal component.
