Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable medical devices with single-use handles contribute to environmental waste and ergonomic issues due to lack of flexibility and interchangeability, leading to increased costs from frequent replacements.
Innovation Solution
A reusable medical device with a handle system comprising movable bodies and actuators that allow for selective attachment and detachment of medical tools, featuring a hinge mechanism and locking system for secure coupling and decoupling, enabling multiple uses and ergonomic adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable medical devices with single-use handles are used, then sterilization and contamination risks are eliminated, but environmental waste increases and ergonomic flexibility is reduced
Solution Approach 1:
The medical device is divided into two distinct segments: a reusable handle assembly and a disposable tool assembly. The handle can be sterilized and reused multiple times, while only the tool portion is discarded after single use. This segmentation allows the handle to be recovered and reused, reducing environmental waste while maintaining sterilization assurance through proper cleaning protocols.
Solution Approach 2:
The invention implements a selective discarding strategy where only the tool portion of the medical device is discarded after single use, while the handle assembly is recovered, cleaned, sterilized, and reused. This approach recovers the majority of the device structure, significantly reducing material waste compared to complete disposal of traditional single-use devices.
2Reliability
If disposable medical devices with single-use handles are used, then contamination risks are minimized, but ergonomic adaptability and user comfort are reduced
Solution Approach 1:
The reusable handle assembly is designed with universal adaptability to accommodate multiple different tool types and configurations. The handle can be coupled with various surgical tools, allowing different users with varying hand profiles to utilize the same ergonomic handle design, thereby providing ergonomic flexibility while maintaining contamination control through the disposable tool portion.
3Adaptability or versatility
If reusable handles with movable bodies and locking mechanisms are used, then ergonomic flexibility and interchangeability are improved, but device complexity increases
Solution Approach 1:
The handle assembly incorporates movable bodies that can transition between locked and unlocked states, allowing dynamic coupling and decoupling of tools. The movable bodies enable the handle to adapt to different tool configurations while maintaining a relatively simple overall structure through straightforward mechanical movements rather than complex multi-component systems.
Solution Approach 2:
The locking mechanism uses simple geometric copying between complementary features on the movable bodies and stationary components. Matching shapes, slots, and engagement surfaces are replicated to ensure proper alignment and secure coupling, achieving reliable locking functionality through basic geometric repetition rather than complex mechanical systems.
4Reliability
If single-use medical devices are replaced entirely after each use, then sterilization concerns are eliminated, but replacement costs increase
Solution Approach 1:
By segmenting the device into reusable and disposable portions, the invention eliminates the need to replace the expensive handle assembly after each use. Only the simpler, less costly tool portion requires replacement, significantly improving cost efficiency while maintaining sterilization assurance through proper handling of the disposable component.
Solution Approach 2:
The invention recovers and reuses the handle assembly which represents the majority of the device cost, while only discarding the tool portion. This selective recovery strategy dramatically reduces replacement costs compared to complete device disposal, as the reusable handle can be sterilized and used across multiple procedures and tool sets.

AI summary
A medical device that includes a handle including a first body and a second body that are movable relative to one another, and an actuator including a first housing movably coupled to the first body and a second housing movably coupled to the second body. The medical device is configured to move between an open configuration in which the first body is at least partially decoupled from the second body and the first housing is at least partially decoupled from the second housing, and a closed configuration in which the first body is coupled to the second body and the first housing is coupled to the second housing.
