Surgical Projection Image Generation for Postoperative State Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mixed reality surgery methods primarily display the preoperative state of a patient's affected area, failing to accurately depict the postoperative shape, which can differ significantly, making it difficult for surgeons to visualize the final state during operations like knee joint restoration or replacement.
Innovation Solution
A surgical assistance apparatus and method that uses image processing to create projection images based on measurement data, showing the affected area's postoperative state, allowing surgeons to project these images onto the patient, thereby enhancing accuracy and precision during surgeries by aligning key anatomical points and indicating referential body parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the preoperative state of the patient is displayed on the patient's body surface, then the surgeon can see the affected area, but the surgeon cannot accurately check the postoperative shape because the displayed image does not show the future state
Solution Approach 1:
The system performs preliminary image processing to create a projection image that depicts the postoperative state before the actual surgery begins. Measurement data from the affected area is processed in advance to generate the projected image showing the future shape, allowing the surgeon to verify the postoperative outcome beforehand.
Solution Approach 2:
The system creates a copy of the postoperative state through image processing. The projection image is a visual representation (copy) of what the affected area will look like after surgery, based on measurement data and predetermined processing, allowing the surgeon to examine the future state without actually performing the surgery yet.
2Manufacturing precision
If the projection image shows the postoperative state, then the surgeon can accurately check the future shape, but the system complexity increases due to additional image processing requirements
Solution Approach 1:
The image processing unit is divided into functional segments: a measurement data obtaining unit that captures data from the affected area, a processing unit that applies predetermined processing to create the postoperative appearance, and a projection image creating unit that generates the final projected image. This segmentation allows each component to handle specific tasks independently.
Solution Approach 2:
The system introduces an intermediary processing stage between the measurement data and the final projection image. The processing unit acts as an intermediary that applies predetermined processing to the measurement data, transforming it into a representation of the postoperative state that can be projected onto the patient.

AI summary
Provided is a surgical assistance apparatus and so on that make it possible to more accurately check the state that an affected part is to be in after a surgical operation has started, in advance of the surgical operation. A surgical assistance apparatus includes an image processing unit. The image processing unit creates projection image data based on measurement data that has been obtained by measuring an affected part of a patient, and thus creates a projection image as an image that is specified by the projection image data. This projection image is an image that is to be projected onto the patient, and includes an image that shows a state that the affected part is to be in after a surgical operation has started.
