Medical Forceps Blocking Element Grip Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical forceps instruments have complex and insecure connection mechanisms, making it difficult for users to ensure proper assembly and operational readiness, which can lead to maloperation.
Innovation Solution
A medical forceps design featuring a blocking element that automatically holds the movable grip in a defined position for secure connection and release, along with a ball locking connection that allows easy assembly and rotation, ensuring correct functioning without precise positioning requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ball locking connection is used to connect the shank and actuation rod to the grip, then the connection is secure, but the assembly becomes awkward and users cannot directly recognize whether both connections are securely locked
Solution Approach 1:
The patent implements a feedback mechanism through a blocking element that automatically prevents movement of the grip when the actuation rod is detached. This provides visual and tactile feedback to the user about the connection status, resolving the issue of unrecognized locking status while maintaining secure connection through the ball locking mechanism
2Adaptability or versatility
If the actuation rod is detachably connected to the movable grip via ball locking connections, then the instrument insert can be exchanged, but the user must precisely position the grip to ensure proper connection
Solution Approach 1:
The blocking element is pre-positioned to automatically block the grip in the correct position when the actuation rod is detached. This preliminary positioning action eliminates the need for users to precisely position the grip during connection, while still allowing easy exchange of instrument inserts through the detachable ball locking connection
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
Simplifies the handling and assembly of medical forceps by providing a secure and self-securing connection mechanism, ensuring the instrument is operational ready and reducing the risk of maloperation.
Implementation Method 1
The blocking element is arranged on the receiver and may be moved by a spring element into a blocking position and by the proximal end of the actuation rod against the spring force of the spring element into a released position

AI summary
A medical instrument has an instrument insert and an instrument handle, which are detachably connected to one another. An actuation rod of the instrument insert is releasably connectable to a movable grip of the instrument handle via a locking connection. A blocking element is provided which blocks the movable grip when the actuation rod has been released.
