Dental Handpiece Cleaning Flow Path Without Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental handpieces require disassembly for effective cleaning and sterilization, complicating the process due to residues in gaps between components.
Innovation Solution
A dental handpiece design with a cylindrical outer body and an insert body containing an ultrasonic vibrator, featuring a cleaning liquid flow path that immerses the insert body in cleaning liquid, allowing for discharge without disassembly, and a detachable cleaning adapter for external liquid supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dental handpiece is disassembled to facilitate cleaning treatment, then cleaning effectiveness is improved, but device complexity and operation complexity increase
Solution Approach 1:
The handpiece is divided into an outer body and an insert body that can be separated. The insert body contains the ultrasonic vibrator and tip connection portion, while the outer body contains the cleaning liquid flow path. This segmentation allows the insert body to be removed and discarded after use, eliminating the need to disassemble internal components for cleaning.
Solution Approach 2:
The insert body is extracted as a separate removable component from the outer body. By taking out the insert body that contains the ultrasonic vibrator and tip connection portion, the cleaning liquid can flow through the outer body to clean the internal channels without requiring disassembly of the handpiece assembly.
2Reliability
If the dental handpiece is disassembled for cleaning, then residue removal is improved, but ease of operation deteriorates
Solution Approach 1:
The handpiece design allows the outer body to be cleaned independently through its built-in cleaning liquid flow path. The cleaning liquid is supplied to the outer body and flows through internal channels to remove residues, while the insert body is simply removed and discarded, eliminating the need for complex manual disassembly and cleaning operations.
3Ease of operation
If a cleaning liquid flow path is added to enable cleaning without disassembly, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cleaning liquid flow path is merged with the outer body structure. The flow path includes a cleaning liquid supply port, a cleaning liquid channel formed within the outer body, and a discharge port. This integration adds cleaning functionality without requiring separate independent components, thus limiting the increase in overall device complexity.

Function Achieved in This Case
Enables thorough cleaning of the handpiece interior without disassembly, improving efficiency and simplifying the cleaning process while ensuring effective residue removal.
Implementation Method 1
an ultrasonic vibrator 17, and a tip connection portion 19 that detachably holds a scaler tip 13 to which ultrasonic vibration from the ultrasonic vibrator 17 is transmitted
Implementation Method 2
a cleaning liquid flow path that guides a cleaning liquid supplied from a cleaning liquid injection port of the insert body to a front end portion of the outer body
Implementation Method 3
the cleaning liquid flow path includes an immersion flow path in which the insert body is immersed in the cleaning liquid in the outer body

AI summary
A dental handpiece includes a cylindrical outer body, an insert body that includes an ultrasonic vibrator, and is accommodated in the outer body, a front end portion of the insert body and a rear end portion of the insert body, a tip connection portion that detachably holds a scale tip to which ultrasonic vibration from the ultrasonic vibrator is transmitted, and a cleaning liquid flow path that guides a cleaning liquid supplied from a cleaning liquid injection port of the insert body to a front end portion of the outer body. The cleaning liquid flow path includes an immersion flow path in which the insert body is immersed in the cleaning liquid in the outer body and the cleaning liquid in which the insert body is immersed is discharged from the front end portion of the outer body.
