Detachable Surgical Instrument Drive for Sterile Battery Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical instruments face issues with product durability and user convenience, particularly in maintaining sterilization integrity and ease of battery replacement, which can lead to contamination and increased risk of damage during sterilization processes.
Innovation Solution
A detachable driving assembly with a sterilizable container and battery pack design that includes a locking mechanism to prevent contamination and ensure easy, guided insertion, along with a rechargeable or disposable battery option that uses RFID technology for authentication and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving assembly is detachably coupled to the manipulation assembly, then ease of battery replacement is improved, but device complexity increases
Solution Approach 1:
The surgical instrument is divided into separate functional modules: the manipulation assembly (handle) and the driving assembly (battery pack). The driving assembly can be detachably coupled to or separated from the manipulation assembly, allowing independent replacement of the battery pack without affecting the main instrument body. This modular segmentation directly improves ease of battery replacement while maintaining manageable device complexity through standardized coupling mechanisms.
2Ease of operation
If the container structure becomes narrower from entrance to inner region, then ease of battery pack insertion is improved, but manufacturing precision requirements increase
Solution Approach 1:
The container is pre-formed with a tapered structure that guides the battery pack during insertion. The narrowing profile from entrance to inner region acts as a built-in alignment mechanism, directing the battery pack into the correct position before final engagement. This preliminary guiding action reduces insertion difficulty and minimizes the need for high-precision manufacturing tolerances, as the geometry itself provides the alignment function.

AI summary
A surgical instrument includes a manipulation part coupled to an end tool connection part and formed to control an operation of an end tool, and a driving unit formed to be detachably attached to the manipulation part and formed to supply a driving force for the operation of the end tool through the manipulation part.
