Jaw-Delivered Needle Suture Device for Hollow-Organ Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical manipulator systems, such as those described in PCT International Publication No. WO 2021/145411, are not efficiently used and do not facilitate effective treatment procedures, particularly in hollow organs like the alimentary canal.
Innovation Solution
A medical system incorporating a suture device with an arm, first and second jaws, and a needle, where the jaws can be opened and closed to deliver the needle, enhancing the efficiency of observation and treatment processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a medical manipulator system is electrically driven to reduce operator fatigue, then operator fatigue is reduced, but the system is not easily used and cannot efficiently perform treatment
Solution Approach 1:
The suture device is configured to automatically deliver the needle through the jaws when they close, and the thread is automatically pulled through the tissue. This self-service mechanism eliminates the need for complex manual manipulation while maintaining high treatment efficiency, thus resolving the contradiction between ease of operation and productivity
2Productivity
If a suture device with movable jaws is added to enable precise suture operations, then treatment efficiency is improved, but device complexity increases
Solution Approach 1:
The suture device combines the needle delivery mechanism, thread pulling function, and jaw movement into a single integrated structure. The first and second jaws work together as a unified system to grasp and deliver the needle, eliminating the need for separate complex mechanisms and reducing overall device complexity while maintaining treatment efficiency
3Manufacturing precision
If the jaws are configured to open and close to deliver the needle, then precise suture operations are enabled, but the mechanism becomes more complex
Solution Approach 1:
The needle acts as an intermediary element that is grasped by the jaws and used to deliver the thread through the tissue. This intermediary approach allows the jaws to perform a simple grasping and releasing function rather than directly manipulating the thread, simplifying the jaw mechanism while maintaining precise suture capability

AI summary
A medical system includes a suture device. The suture device includes: an arm; a first jaw and a second jaw that are attached to a distal end of the arm; and a needle configured to attach a thread. At least one of the first jaw and the second jaw configured to be opened and closed to deliver the needle therebetween.
