Malleable Tool Bending Jig With Angle-Guided Straightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Malleable medical tools are difficult for physicians to bend to a desired shape, and correcting an incorrectly bent tool with crimps is challenging.
Innovation Solution
A jig apparatus with a conical recess and an elongated cylindrical hole allows for precise bending and straightening of malleable tools, featuring angular markings to indicate bending angles, enabling accurate shaping of the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a physician attempts to bend a malleable tool by hand, then the tool can be shaped, but it is difficult to achieve the desired shape and correcting crimps is challenging
Solution Approach 1:
The patent introduces a jig as an intermediary device between the physician and the malleable tool. The jig includes a conical recess with angular markings that serves as a mediator to guide the bending process, providing reference lines for desired bending angles and a controlled environment for shaping the tool without direct hand manipulation
Solution Approach 2:
The jig prepares the bending environment in advance by providing pre-marked angular references and a conical recess structure. The angular markings are predetermined to indicate specific bending angles, allowing the physician to perform the bending action with clear guidance rather than attempting to estimate angles during the actual bending process

AI summary
In one embodiment, a jig apparatus for bending a malleable tool includes a block having an upper surface and containing, a conical recess extending into the block through the upper surface of the block, defined by an elliptical directrix on the upper surface, an apex within the block, and generatrixes disposed about a central axis of the conical recess extending from the apex to the directrix, and an elongated cylindrical hole, which is sized to fit the malleable tool therein and has a longitudinal axis extending from the conical recess into the block at an oblique angle relative to the central axis of the conical recess, and angular markings disposed on the upper surface and around a circumference of the elliptical directrix.
