Dual Fan Beam Guide Line for Penetration Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for guiding penetration instruments into objects, such as computed tomography systems, often fail to maintain precise alignment due to obstacles within the object, leading to inaccurate insertion of instruments like catheters or needles.
Innovation Solution
A method using two light fan beams emitted from different directions, with their intersection line aligned coaxially with the penetration direction, which is corrected based on real-time measurement data from imaging systems, ensuring the instrument follows the optimal penetration channel even if it bends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light beam is used for marking out the guide line, then the device complexity is low, but the visibility and accuracy of the guide line is insufficient
Solution Approach 1:
The patent combines multiple light beams (at least two light beams) to form a unified guide line marking system. The light beams are merged to create an intersection line that serves as the guide line, enhancing visibility while maintaining coordinated control through the control device.
Solution Approach 2:
The patent transitions from using a single light beam to using multiple light beams that intersect to form a line. This dimensional change from point/line to intersecting planes creates a more visible and accurate guide line through the intersection of multiple beam dimensions.
2Adaptability or versatility
If the penetration instrument follows a straight penetration channel, then the insertion process is simple, but it cannot accommodate obstacles or complex anatomical structures
Solution Approach 1:
The patent implements a dynamic marking out system where the light beams and their intersection line can be moved and adjusted in real-time. The control device enables dynamic repositioning of the light beams to follow the penetration instrument's progression and adapt to changing anatomical conditions while maintaining alignment precision.
Solution Approach 2:
The patent incorporates a feedback mechanism where the position of the penetration instrument is detected and used to control the repositioning of the light beams. This closed-loop feedback ensures the guide line remains accurately aligned with the penetration channel even as the instrument navigates complex structures.
3Ease of operation
If the light beams are fixed in position, then the device complexity is low, but the guide line cannot be adjusted to follow the penetration instrument's movement
Solution Approach 1:
The control device serves multiple functions: it controls the positioning of multiple light beams, detects the position of the penetration instrument, calculates the appropriate repositioning, and adjusts the beams in real-time. This multi-functionality enables ease of operation while consolidating complexity into a single integrated control system.

Function Achieved in This Case
This approach significantly enhances the visibility and accuracy of the guide line, allowing users to precisely align the penetration instrument with the penetration direction, even in complex anatomical structures, by using visible red fan beams that can be easily recognized and adjusted during insertion.

AI summary
A method is disclosed for marking out a guide line of a penetration instrument entering an object along a penetration channel. In at least one embodiment, the penetration channel into the object is firstly determined based on image data of the object generated by an imaging recording system, the penetration channel being defined by a penetration point into the object and at least one penetration direction. Then, at least two light fan beams are emitted from different directions in such a fashion that the line of intersection of the fan beams is coaxial with the penetration direction. A marking out apparatus is further disclosed for carrying out the method, along with a control device suitable to this end, and an imaging recording system including such a marking out apparatus.
