Adjustable Vascular Constricting Device with Rotating Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for fastening or constricting tissues or items lack adjustable and secure mechanisms, particularly in medical and minimally invasive surgeries, where precise control over constriction is necessary without causing accidental disengagement.
Innovation Solution
A device comprising a pin element with a locking structure and a ring element that can be rotated to adjust the constriction level, featuring a band element that forms a closed loop around the tissue or item, allowing for adjustable and secure fastening or constriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical sutures or clips are used to fasten or constrict tissue, then the fastening function is achieved, but the ability to adjust the degree of constriction is lost and accidental disengagement may occur
Solution Approach 1:
The ring element is designed to rotate along the pin element, allowing dynamic adjustment of the band element's tension and the degree of constriction applied to the tissue. This rotational mechanism transforms a static fastening system into a dynamic one, enabling the surgeon to adjust constriction levels while maintaining secure attachment through the locking structure.
2Measurement precision
If a fixed constriction device is used, then the device structure is simple, but the precision of constriction control is insufficient
Solution Approach 1:
The device is segmented into distinct functional components: a pin element with locking structure, a rotatable ring element, and a band element. This segmentation allows each component to perform its specific function independently, providing precise constriction control through the rotational adjustment of the ring while keeping the overall device structure relatively simple and manageable.
3Ease of operation
If a removable fastening mechanism is used, then ease of removal is improved, but the risk of accidental disengagement increases
Solution Approach 1:
The locking structure on the pin element is designed to prevent accidental disengagement by requiring a specific intentional action (rotation in a particular direction) to release the ring element. This preliminary anti-action mechanism ensures that the fastening remains secure during normal use while still allowing easy removal when deliberately intended by the surgeon.

AI summary
This document relates to methods and materials involved in fastening or constricting. For example, devices (e.g., adjustable vascular pedicle constricting devices) configured to allow a user (e.g., a surgeon) to apply a band element at least partially around a desired structure (e.g., tissue such as a vascular pedicle) in a manner that allows the degree of constriction to be adjustable are provided.
