Locking Dental Forceps for Lower-Strain Tooth Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tooth extraction methods require significant manual stress and strain on the dentist, necessitating precise control of compressive, lateral, and upward forces to avoid complications, while conventional forceps designs do not adequately alleviate this strain.
Innovation Solution
A locking mechanism is integrated into dental forceps, allowing secure grip and tension adjustment, reducing manual stress by enabling quick and secure tooth engagement and release, with interchangeable beaks and handles for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional dental forceps are used with separate locking mechanisms for each jaw, then each jaw can be controlled independently, but the device complexity increases and cross-contamination risk increases
Solution Approach 1:
The patent combines two separate locking mechanisms into a single unified locking mechanism that controls both upper and lower jaws simultaneously. The locking block engages with both jaw levers through a shared locking surface, allowing one locking action to secure both jaws, thereby reducing device complexity while maintaining independent jaw control capability
Solution Approach 2:
The patent segments the locking mechanism into distinct functional components: a locking block with differentiated locking surfaces for each jaw, allowing the single locking mechanism to independently engage with both upper and lower jaw levers through separate engagement points, thus maintaining independent control capability
2Reliability
If conventional dental forceps require multiple cleaning procedures for different jaws, then thorough sterilization can be achieved, but the time required for preparation increases
Solution Approach 1:
The patent merges the cleaning process for both jaws into a single simultaneous cleaning action. The cleaning member engages with both upper and lower tooth extraction portions at the same time through its dual-sided configuration, allowing one cleaning motion to sterilize both jaws, thereby reducing preparation time while maintaining sterilization completeness
3Device complexity
If dental forceps have a fixed jaw opening angle, then the structure is simpler, but adaptability to different tooth positions is reduced
Solution Approach 1:
The patent implements a dynamic jaw opening angle mechanism where the lower jaw lever can rotate relative to the upper jaw lever around a fulcrum point. This allows the jaw opening angle to be adjusted during operation to match different tooth positions and extraction angles, providing adaptability without requiring complex mechanical adjustment devices
Solution Approach 2:
The patent uses asymmetric positioning of the fulcrum point and differentiated locking surfaces on the locking block to enable different engagement characteristics for upper and lower jaws, allowing the forceps to adapt to various tooth orientations and extraction vectors while maintaining a relatively simple overall structure

AI summary
A denial forceps includes a first, elongate member having a first beak portion and a second elongate member including a second beak portion. The first elongate member and the second elongate member are connected to each other at a pivot point that allows the elongate members to rotate with respect to each other. The dental forceps also includes a locking arm that is connected to one of the elongate members. The locking arm engages a series of teeth that is positioned on the other elongate member. While the locking arm engages the series of teeth, the position of the elongate members with respect to one another is maintained.
