Integrated Surgical Table Imaging for Sterile Patient Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional external 3D interoperative imaging devices for surgery are bulky, obstruct access to the patient, require time-consuming recalibration, increase radiation dosage, and pose sterility risks due to their repositioning during surgery.
Innovation Solution
An integrated imaging device is mounted on the surgical table, allowing precise positioning and calibration, reducing recalibration time, radiation exposure, and maintaining sterility by eliminating the need for external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external imaging device is used, then imaging functionality is provided, but the device is bulky and obstructs access to the patient
Solution Approach 1:
The imaging device is integrated into the surgical table by mounting it on the table's base structure. The imaging device support is connected to the base, combining the surgical table and imaging device into a single integrated system. This eliminates the need for separate external imaging devices that obstruct patient access.
2Adaptability or versatility
If the imaging device is repositioned during surgery, then imaging of different areas is enabled, but time-consuming recalibration is required
Solution Approach 1:
The imaging device is pre-calibrated to the surgical table coordinate system during integration. The relative position between the imaging device and surgical table is established once, and this calibration is maintained throughout the procedure. The imaging device can be repositioned along the longitudinal axis without requiring recalibration, as the integrated system maintains consistent spatial relationships.
3Adaptability or versatility
If the imaging device is repositioned frequently, then different patient areas can be imaged, but radiation dosage increases
Solution Approach 1:
The imaging device maintains continuous operational readiness through pre-calibration, allowing seamless imaging of different patient areas without interruption for recalibration. The device can be smoothly repositioned along the surgical table's longitudinal axis, maintaining optimal imaging conditions throughout the procedure and reducing the need for repeated high-dose radiation exposures.
4Reliability
If an external imaging device is used, then imaging functionality is provided, but sterility violations may occur
Solution Approach 1:
The imaging device is integrated into the surgical table structure, which is part of the sterile surgical field. The imaging device support is mounted on the base of the surgical table, creating a unified system where the imaging device moves with the table. This integration eliminates the need for separate external devices that may compromise sterility during positioning and repositioning.

Data Source
AI summary
A surgical table with an integrated imaging device can obtain images of a patient's body part. The surgical table can include a base, a patient support platform, at least one platform support connected to the base, and an imaging device support that is mounted on the base and an imaging device mounted on the imaging device support. The patient support platform can be at least partially positioned between a first arm and a second arm. A first radiation source can be positioned in or on the first arm and a first radiation detector can be positioned in or on the second arm, with the first radiation detector arranged to detect at least a portion of the radiation emitted by the first radiation source.
