Surgical Wire Twisting Tool with Locking Jaws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons face challenges in securely twisting surgical wire due to the need for firm and steady handling, which can lead to wire breakage or improper approximation when manipulating additional surgical apparatus simultaneously.
Innovation Solution
A surgical wire twisting tool designed for one-handed operation, featuring a hollow housing, plunger, rotating member, and jaw actuating rod, with pivotally mounted jaws that can be selectively opened, closed, and locked, allowing for controlled wire clamping and twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional forceps are used to hold and twist surgical wire, then the surgeon can manipulate the wire, but the surgeon cannot maintain full control when manipulating additional surgical apparatus, leading to wire breakage or incorrect approximation
Solution Approach 1:
The patent combines the wire holding function and wire twisting function into a single integrated device. The locking jaws securely hold the wire while the rotating member provides controlled twisting motion, eliminating the need to switch between different instruments and maintaining continuous control over the wire throughout the procedure
Solution Approach 2:
The device performs multiple functions: it can clamp and hold the wire securely with locking jaws, rotate the wire through the rotating member, and twist the wire to the desired degree. This multi-functionality allows the surgeon to complete the entire wire twisting procedure with one instrument, improving both ease of operation and reliability
2Productivity
If the surgeon uses conventional forceps and manually twists the wire, then the twisting can be performed, but the surgeon requires full attention and steady handling, which is challenging when manipulating additional apparatus
Solution Approach 1:
The device is designed for self-contained operation where the rotating member and locking mechanism work together to maintain wire control automatically. Once the wire is secured in the locking jaws, the device maintains its position and control without requiring continuous manual adjustment or full surgeon attention, allowing the surgeon to perform other tasks simultaneously
3Reliability
If conventional forceps are used for wire twisting, then the procedure can be performed, but the risk of wire breakage and incorrect approximation increases
Solution Approach 1:
The patent combines the wire holding function and wire twisting function into a single integrated device. The locking jaws securely hold the wire while the rotating member provides controlled twisting motion, eliminating the need to switch between different instruments and maintaining continuous control over the wire throughout the procedure
Solution Approach 2:
The device incorporates a rotating member that can be selectively rotated to twist the wire to the desired degree. This dynamic component allows for controlled, incremental twisting motion while the locking jaws maintain secure grip, providing precise control over the wire twisting process and reducing the risk of wire breakage or incorrect approximation

AI summary
The surgical wire twisting tool includes a hollow housing, a plunger, a rotating member, a jaw actuating rod and a hollow cylindrical guide. A portion of the plunger is received within a second end of the hollow housing, and the rotating member is received within the hollow housing, such that a portion of the rotating member projects through a first end of the hollow housing. A pair of jaws are mounted on one end of the jaw actuating rod. The hollow cylindrical guide is received within the hollow housing, such that the other end of the jaw actuating rod projects through a second end of the rotating member and into the hollow cylindrical guide. The plunger slides through a second end of the hollow cylindrical guide to drive movement of the jaw actuating rod. The pair of jaws may be rotated with respect to the hollow housing, and also locked.
