In-body Camera Connector for Foreign Matter Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-body monitoring camera systems face issues with electrical connection failures due to foreign matter and difficulty in achieving strong cable connections and adjusting camera orientations during endoscopic surgery.
Innovation Solution
The system includes a support tube with a joining portion inside the body, a cable connected to the imaging portion, and a control system outside the body, allowing for secure cable insertion and easy camera orientation adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector electrode is directly inserted into the abdominal wall and joined with the camera inside the body, then the camera can be positioned inside the body, but electrical connection failure occurs due to foreign matter in the joining portion
Solution Approach 1:
The patent introduces a connector as an intermediary component between the cable and the imaging portion. The connector includes a cable connection portion and an imaging portion connection portion, serving as a mediator that prevents direct contact between the cable and imaging portion, thereby blocking foreign matter contamination while maintaining electrical connection reliability
Solution Approach 2:
The patent divides the connection system into separate segments: the cable, the connector, and the imaging portion. By segmenting the joining portion into distinct components (cable connection portion and imaging portion connection portion), the system prevents foreign matter contamination while maintaining reliable electrical connection
2Strength
If the communication cable is led out to the outside of the body to be fixed, then the cable can be secured, but joining strength between the communication cable and the camera unit cannot be obtained
Solution Approach 1:
The connector serves as a mediator that provides a secure joining interface between the cable and the imaging portion. The cable connection portion of the connector enables strong mechanical and electrical connection without requiring the cable to be led out to the outside of the body, thereby achieving both joining strength and ease of operation
3Adaptability or versatility
If the communication cable is led out to the outside of the body to be fixed, then the cable can be secured, but the orientation of the camera unit cannot be changed from outside the body
Solution Approach 1:
The connector includes a rotation portion that enables dynamic adjustment of the imaging portion's orientation. This rotation mechanism allows the camera unit's orientation to be changed from outside the body, providing adaptability while maintaining ease of operation through external control
