Self-fixating Surgical Visualization Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic and laparoscopic surgical procedures face limitations due to the direct integration of cameras onto surgical instruments, which compromises manipulation and flexibility, and often result in a lack of global visualization of the surgical site.
Innovation Solution
An integrated surgical visualization system that includes self-fixation and stabilization substrates with imaging devices and illumination sources, allowing for global visualization of the surgical site without the need for secondary visualization sources like scopes, using substrates with fasteners, barbs, or adhesives to attach to patient tissue and provide a comprehensive view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the camera is directly integrated onto the surgical instrument, then the surgeon can observe the immediate surgical site, but the surgeon loses the ability to manipulate the camera and surgical tools independently and cannot achieve a global view of the surgical site
Solution Approach 1:
The system divides the visualization function into separate components: a dedicated visualization device with camera and illumination is separated from the surgical instruments. This allows the camera to be positioned independently to capture a global view of the surgical site while surgical tools can be manipulated separately without interference, resolving the contradiction between obtaining a global view and maintaining ease of manipulation.
Solution Approach 2:
The patent introduces a separate visualization device as an intermediary component that captures images of the surgical site and transmits them to a display system. This intermediary device enables the surgeon to view the global surgical field without the camera being physically attached to the surgical instruments, thus maintaining independent manipulation of both camera and surgical tools.
2Device complexity
If the camera and surgical tools are introduced through working channels of the instrument, then integration is achieved, but the flexibility of the instrument is compromised
Solution Approach 1:
The camera and illumination components are extracted from the surgical instrument's working channels and implemented as a separate visualization device. This extraction eliminates the space occupation and interference caused by embedding cameras within instrument channels, thereby preserving the full flexibility and adaptability of the surgical instruments while still achieving integrated visualization functionality through external mounting options.
3Ease of operation
If the instrument is navigated through tortuous paths, then access to the surgical site is achieved, but the rotational orientation of the instrument may not be aligned with the expected surgical view
Solution Approach 1:
The visualization device is designed with dynamic positioning capabilities, allowing the camera to be rotated and oriented independently of the surgical instrument's position. This dynamic adjustment enables the camera to capture the expected surgical view even when the instrument is navigated through tortuous paths, as the camera orientation can be optimized separately from the instrument's navigational constraints.
4Device complexity
If the camera and associated wiring are present within the instrument, then visualization is integrated, but space is taken up and the procedure may be interfered with
Solution Approach 1:
The visualization device utilizes flexible mounting mechanisms and thin-film connections that allow the camera to be positioned close to the surgical site without requiring bulky wiring within the instrument. The flexible design minimizes space occupation and reduces potential interference with surgical procedures while maintaining integrated visualization functionality.
