Automatic Anatomical Side Assignment in Surgical Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical navigation methods, accurately assigning symmetrical anatomical parts of the body, such as the right and left lower leg bones, to their corresponding sides is challenging due to their congruent shapes and perspectives, leading to potential errors and manual input inefficiencies.
Innovation Solution
A method that uses anatomical point data and landmark data to automatically determine the region of the body by comparing spatial patterns of patient landmarks with model landmarks, utilizing a pointer and marker devices to digitize and process spatial coordinates, allowing for automatic assignment of anatomical parts to their respective sides without user input.

Engineering Contradiction Analysis
1Reliability
If manual input is used to assign anatomical parts to body sides, then the surgeon can directly input side information, but this leads to time consumption and potential input errors
Solution Approach 1:
The system automatically determines the side of anatomical parts by itself, without requiring surgeon input. The data processing device compares spatial patterns of patient landmarks with model landmarks and autonomously assigns the correct side (right or left), making the system self-servicing in terms of side determination.
Solution Approach 2:
The manual mechanical process of surgeon input is replaced by an automated computational system. The data processing device uses algorithmic comparison of spatial patterns and coordinates to determine side assignment, substituting human manual operation with automated information processing.
2Adaptability or versatility
If symmetrical anatomical parts are observed from different perspectives, then the congruent shapes provide flexibility in viewing, but this makes it difficult to clearly distinguish and assign the correct side
Solution Approach 1:
The system moves from two-dimensional visual assessment to three-dimensional spatial pattern analysis. By using spatial coordinates and patterns of multiple landmarks in 3D space, the system creates an additional dimensional framework that allows unambiguous side determination regardless of the observer's perspective or the congruent appearance of symmetrical parts.
Solution Approach 2:
The system introduces spatial pattern data and coordinate information as an intermediary between the anatomical parts and the side assignment decision. This intermediary data layer provides objective measurable characteristics that resolve the ambiguity created by symmetrical appearances and different viewing perspectives.

AI summary
The present invention relates to a method for determining the region of the body in which an anatomical part of the body is situated, said method including the following steps:anatomical point data is provided which includes information concerning a spatial pattern of positions of patient landmarks of a part of a patient's body which corresponds to the anatomical part of the body;landmark data is provided which includes information concerning a spatial pattern of positions of model landmarks of a model of the anatomical part of a patient's body;wherein, assuming thatthe patient landmarks represent the same landmarks as the model landmarks,the region of the body in which the part of the patient's body is situated is determined on the basis of the landmark data and the anatomical point data.
