Solution Overview
Problem
Current surgical imaging systems are limited in their ability to recognize and convey information about concealed structures and dimensions within a three-dimensional space, leading to uncertainty in the location of critical anatomical structures during surgical procedures, which can result in inaccurate dissection and potential damage to vital tissues.
Innovation Solution
A surgical visualization system that incorporates a control circuit capable of generating images based on electromagnetic radiation, defining coordinate systems, and providing transfer functions to adjust surgical instrument controls, allowing for improved orientation and control of surgical instruments relative to a global coordinate system, thereby enhancing the clinician's understanding of the surgical site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional imaging systems are used to view the surgical site, then the system structure remains simple, but the ability to recognize and convey information about concealed structures and three-dimensional dimensions is insufficient
Solution Approach 1:
The patent introduces a coordinate system transformation mechanism that maps three-dimensional surgical site coordinates to two-dimensional display coordinates and back. This dimensional transformation enables the imaging system to convey depth and spatial relationship information that would otherwise be lost in traditional 2D imaging, allowing clinicians to understand concealed structures and 3D dimensions without fundamentally changing the imaging hardware.
Solution Approach 2:
The patent employs a coordinate system as an intermediary between the physical surgical site and the displayed image. By defining a transfer function that translates coordinates between the surgical site coordinate system and the display coordinate system, the system mediates the information gap, enabling accurate representation of concealed structures without requiring complex imaging hardware modifications.
2Ease of operation
If the surgical instrument orientation is not adjusted to match the display coordinate system, then the control system remains simple, but user confusion and disorientation increase
Solution Approach 1:
The patent implements a feedback mechanism where the control system continuously monitors the surgical instrument's orientation and automatically adjusts it to match the display coordinate system. The transfer function provides real-time feedback about the relationship between instrument position and displayed position, enabling the system to self-correct and maintain alignment without user intervention, thereby improving ease of operation.
Solution Approach 2:
The patent dynamically changes the orientation parameters of the surgical instrument based on the coordinate system transformation requirements. By adjusting the instrument's rotational and positional parameters in real-time according to the transfer function, the system ensures that the physical instrument orientation always corresponds to the displayed orientation, eliminating user confusion without requiring complex manual coordination.
3Measurement precision
If coordinate system transformation is implemented to improve surgical precision, then the accuracy of surgical site localization improves, but the control system complexity increases
Solution Approach 1:
The patent establishes the coordinate system transformation and transfer function in advance, before the actual surgical procedure begins. By pre-defining the relationship between the surgical site coordinate system and the display coordinate system, the system prepares the mathematical framework needed for accurate localization, eliminating the need for complex real-time calculations during surgery and reducing overall system complexity.
