Surgical Wire Manipulation Instrument with Integrated Bending and Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical instruments lack an efficient means to manipulate bent surgical wires, particularly in stabilizing and bending them in specific shapes for precise positioning and cutting, which is crucial for bone fixation procedures.
Innovation Solution
A surgical instrument with jaws that can move relative to each other, featuring a wire-receiving device in the form of a groove or slot to stabilize the wire, a wire-bending device with a bending die and ram, and a wire-cutting device, allowing for precise manipulation of wires in shapes like U, L, or V, and enabling varying distances between wire ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate instruments are used for wire manipulation (cutting forceps, bending forceps), then each instrument can be optimized for its specific function, but the procedural complexity and time increase
Solution Approach 1:
The patent combines cutting forceps and bending forceps into a single integrated instrument. The forceps include a first jaw with a cutting edge for wire cutting and a second jaw with a bending nose for wire bending, allowing both functions to be performed with one instrument rather than requiring separate tools for each operation
Solution Approach 2:
The forceps are designed with multi-functional capabilities where the same instrument can perform both cutting and bending operations on surgical wires. The jaws are configured to accommodate different wire manipulation tasks, making the forceps a universal tool for wire preparation in bone fixation procedures
2Ease of operation
If wire manipulation is performed without stabilization, then the instrument is simpler to operate, but the positioning precision and bending accuracy decrease
Solution Approach 1:
The forceps incorporate specialized features on the jaws including a cutting edge on one jaw and a bending nose on the other jaw. These localized structural modifications provide stable positioning and precise control for specific wire manipulation tasks while maintaining overall ease of operation
Solution Approach 2:
The bending nose acts as an intermediary element between the jaw and the wire, providing a controlled surface for bending operations. This intermediary structure ensures accurate wire bending by distributing forces evenly and maintaining consistent positioning during the bending process

AI summary
What is described is a surgical instrument for manipulating a bent surgical wire. The surgical instrument is particularly suitable for inserting one or both ends of a wire, which is bent in the shape of a U, in apertures provided for that purpose in a bone plate. The instrument possesses two jaws that can be moved relative to one another for the purpose of generating a gripping force, at least one of the jaws having a wire-receiving device which positions a bent wire, which is to be received, in a plane substantially parallel to the direction of gripping force.
