Endoscopic Camera Cable Retrieval Using Magnetic Clamp Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems for endoscopic surgery face challenges in efficiently guiding and retrieving camera cables through the abdominal wall, with concerns about cable disconnection and limited visibility during procedures.
Innovation Solution
A camera system with a control unit outside the body, a cable connected to an imaging unit, and auxiliary tools that use a magnet to securely hold and draw out the cable through a tube-like device, ensuring easy retrieval and improved work efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle-like connector electrode or hooking needle is used to guide the cable through the abdominal wall, then the cable can be inserted into the body, but there is a concern that the cable may come off of the needle in the abdominal wall
Solution Approach 1:
A clamp member is introduced as an intermediary component between the cable and the needle-like auxiliary tool. The clamp member includes a clamp body that clamps the cable and a clamp protrusion that engages with the auxiliary tool, creating a reliable connection mechanism that prevents cable disconnection while maintaining ease of operation
Solution Approach 2:
The connection system is divided into separate functional components: the cable, the clamp member (with clamp body and clamp protrusion), and the auxiliary tool (with engagement groove and engagement protrusion). This segmentation allows each component to perform its specific function optimally while working together as a integrated system
2Loss of information
If the camera is inserted into the body to monitor the inside, then imaging can be performed, but the visual field becomes extremely narrow when the endoscope approaches the organ
Solution Approach 1:
The camera system is designed to provide multiple viewing perspectives simultaneously - both the narrow view from inside the body cavity and the wider view from outside the work region. This multi-functional imaging capability allows practitioners to monitor both the surgical site and surrounding areas without additional equipment
3Ease of operation
If the communication cable is drawn out through the abdominal wall hole while hooked to the hooking needle, then the cable can be retrieved, but there is a concern that the communication cable comes off of the needle
Solution Approach 1:
The clamp member serves as a mediator between the cable and the auxiliary tool during the retrieval operation. The clamp body secures the cable while the clamp protrusion engages with the engagement groove in the auxiliary tool, ensuring the cable remains securely connected throughout the drawing-out process
Solution Approach 2:
The clamp member is pre-positioned on the cable before insertion, and the auxiliary tool is designed with pre-formed engagement features (engagement groove and protrusion). This preliminary preparation ensures that when the cable is drawn out, the connection is already established and maintained throughout the operation

AI summary
A camera system for monitoring the inside of a body having excellent work efficiency is suggested. The camera system for monitoring the inside of a body includes: a cable (12) in which one end is connected to the imaging part; a first auxiliary tool (8) which is connected to the other end of the cable (12); and a second auxiliary tool (7) which includes a holding unit (7g) which holds a held unit (8g) provided in the first auxiliary tool (8), and a rod-like unit (7x) connected to the holding unit (7g), and which draws out the held unit (8g) toward the outside of the body from the inside of the body through the inside of a tube-like device (6) of which one end is guided toward the inside of the body, in a state of being held by the holding unit (7g).
