Surgical Cutter Guide and Guard Mechanism for Safe Ring Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing rings from the body, especially in cases of swelling or deformation, pose risks of injury due to the need for manual cutting, which can result in severe wounds.
Innovation Solution
A surgical cutting tool with a guide and two guards, each with a cutting blade, that allows for controlled clamping and cutting of the ring, minimizing exposure of the wearer to the blades and ensuring safe removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cutting methods are used to remove rings, then the ring can be cut and removed from the body, but the risk of injury and severe wounds increases
Solution Approach 1:
The patent introduces a guide as an intermediary component that the ring is placed upon, and cutting blades that extend through the guide. The guide acts as a mediator between the user's cutting action and the ring, allowing controlled cutting while the guide structure prevents uncontrolled blade movement that could cause severe injuries. The guide protects the wearer by providing a stable reference and limiting blade exposure.
Solution Approach 2:
The patent employs preliminary protective measures by providing guards that cover the cutting blades before use and a guide that is positioned on the body part before the ring is placed on it. The guide is pre-positioned to establish a safe cutting path, and the guards are prepared to protect against accidental blade exposure during the cutting process.
2Productivity
If cutting blades are exposed to cut the ring, then the ring can be effectively cut, but the wearer is exposed to potential blade contact and injury
Solution Approach 1:
The guide serves as an intermediary structure that the cutting blades extend through, allowing the blades to access and cut the ring while the guide body remains in place to protect the wearer. The guide acts as a barrier that limits blade movement to a controlled path, preventing accidental contact with the wearer's skin.
Solution Approach 2:
The guards are prepared in advance to cover the cutting blades before the cutting operation begins. These protective guards are positioned to shield the blades from accidental exposure to the wearer's body, and only move out of the way when controlled cutting is required.
3Reliability
If a guide structure is used to control blade movement, then the safety and control of cutting is improved, but the device complexity increases
Solution Approach 1:
The patent divides the cutting apparatus into distinct functional segments: a guide component that provides structural support and control, cutting blades that perform the cutting function, and guards that provide protection. This segmentation allows each component to perform its specific function independently, making the overall system more reliable while keeping individual components relatively simple.
Solution Approach 2:
The guide structure serves multiple functions simultaneously: it provides a stable base for the cutting blades, guides their movement along a controlled path, protects the wearer from uncontrolled blade movement, and supports the ring during the cutting process. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool enables safe and controlled removal of rings by using a scissor-like mechanism to apply a clamping force, reducing the risk of injury to the wearer and ensuring effective cutting through the ring material.
Implementation Method 1
a blade spring disposed about and along the blade pin. The blade spring is compressed between the third edge of each of the first and the second blades and the respective first and second handles

AI summary
An apparatus and method are provided for surgical removal of a ring. The apparatus includes guards rotatably connected, handles rotatably connected to the guards that each include a portion partially disposed within the respective guard, a guide connected to the guards, and blades disposed on the portion of the handles. The blades contact with at least one of the guide and an inner surface of the respective guard. A rotational axis of a joint between the guards, a rotational axis of a first handle and a first guard, and a rotational axis of a second handle and a second guard are substantially parallel. Movement of a first end of the first handle toward a first end of the second handle results in movement of a second end of the first handle toward a second end of the second handle, and movement of a first blade toward a second blade.
