Biopsy System GUI for Visualizing Cutting Member Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrosurgical biopsy instruments lack visual feedback for surgeons to determine the location of the cutting end within the patient's body during procedures, making it difficult to accurately access and extract tissue specimens.
Innovation Solution
A graphical user interface (GUI) is integrated into the biopsy system, featuring distinct areas to represent regions from which tissue specimens have been or can be separated, providing visual feedback to surgeons on the orientation and position of the tissue cutting member within the patient's body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a small instrument is inserted into the patient's body to access the targeted site, then surgical intrusion is minimized, but visual feedback on the cutting member's location is lost
Solution Approach 1:
The patent creates a visual copy or representation of the internal target site and cutting member position on an external display device. The graphical user interface displays a visual model that replicates the anatomical structure and the position of the cutting member, allowing the surgeon to see the internal state without increasing physical intrusion into the patient's body.
Solution Approach 2:
The patent introduces an intermediary system consisting of sensors, processors, and display devices that mediate between the cutting member inside the body and the surgeon's visual perception outside the body. This intermediary system transmits positional information from the cutting member to the display, enabling visual feedback without requiring direct line of sight to the surgical site.
2Device complexity
If the cutting end is not visible from outside, then the instrument design remains simple, but it becomes difficult for the surgeon to determine the location of the electrosurgical biopsy instrument
Solution Approach 1:
The system creates a visual copy of the cutting member's position and the target site anatomy on an external display. This graphical representation allows the surgeon to detect and measure the location of the cutting member without complicating the physical design of the biopsy instrument itself.
Solution Approach 2:
The patent transitions the visualization from the physical three-dimensional surgical field to a two-dimensional graphical display interface. By projecting the cutting member's position onto a display screen, the system enables detection and measurement of location in an alternative dimensional space that is accessible to the surgeon's vision.
3Measurement precision
If visual display of the cutting member's location is added, then the surgeon can control the biopsy operation more accurately, but the device complexity increases
Solution Approach 1:
The system uses a graphical copy or virtual representation of the target site and cutting member position to improve measurement precision. By displaying a visual model that shows the exact location and orientation of the cutting member, the surgeon can make more precise control decisions without requiring complex physical modifications to the biopsy instrument.
Solution Approach 2:
The patent implements a feedback system where the position of the cutting member is continuously monitored and displayed on the graphical user interface. This real-time feedback loop allows the surgeon to see the effect of their actions and make adjustments to achieve more accurate specimen collection, improving precision through information feedback rather than mechanical complexity.

AI summary
A graphical user interface is disclosed for a tissue biopsy system having a tissue cutting member adapted for cutting one or more tissue specimens from tissue at a target site within a patient. The graphical user interface includes a first GUI area representing a first region of the target site from which the tissue cutting member has separated one or more tissue specimens. The graphical user interface further includes a second GUI area, visually distinguishable from the first GUI area, representing a second region from which the tissue cutting member may separate one or more additional tissue specimens from tissue at the target site.
