Remote Magnetic Traction System for Minimally Invasive Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mini-invasive surgery techniques require multiple incisions, leading to post-surgery pain, bleeding risk, infection, and scarring, which increases recovery time and healthcare costs, and complicates surgical procedures.
Innovation Solution
A guide and remote traction system for mini-invasive surgery that includes a detachable self-closing endoclamp and remote magnetic traction means, allowing for easy positioning and hooking of the endoclamp within the body cavity with minimal incisions, using a magnetic field to manipulate tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple incisions are made to perform surgical procedures, then surgical access and manipulation capability are improved, but post-surgery pain, bleeding risk, infection risk, and scarring increase
Solution Approach 1:
The patent replaces mechanical manipulation through multiple incisions with magnetic field-based remote manipulation. The magnetic clamp responds to external magnetic fields to achieve tissue grasping and manipulation without requiring physical insertion of multiple surgical instruments through multiple incisions, thereby reducing surgical trauma while maintaining operational capability
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the surgeon and the tissue. The magnetic clamp acts as a mediator that transmits magnetic force from external magnets to the tissue, enabling remote manipulation through a single incision or even needle puncture, thus reducing the need for multiple direct mechanical access points
2Reliability
If conventional clamps are manipulated directly through working ports, then tissue grasping capability is improved, but the number of incisions and surgical complexity increase
Solution Approach 1:
The patent replaces direct mechanical manipulation of clamps through working ports with magnetic field-based remote manipulation. The magnetic clamp is actuated by external magnets positioned outside the body, eliminating the need for complex mechanical transmission systems through multiple incisions while maintaining reliable tissue grasping capability
Solution Approach 2:
The patent extracts the control mechanism of the clamp from the surgical field. Instead of manipulating the clamp through mechanical linkages passed through working ports, the control magnets are removed and positioned externally, allowing the clamp to be actuated remotely without adding complexity to the surgical procedure
