Reusable Stapler with Detachable Adapter for Infection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical endoscopic cutting staplers face issues of unstable cutting, low firing force, laborious operation, high cost, and risk of cross-infection due to non-sterilizable handles and disposable nature.
Innovation Solution
A reusable stapler design featuring a detachable adapter, where the handle is sterilizable and reusable, and the adapter is disposable, allowing for reliable and convenient operation with reduced infection risk and lower costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reusable handle is used without a detachable adapter, then the handle can be sterilized and reused to reduce costs, but the adapter cannot be properly sterilized and creates cross-infection risk
Solution Approach 1:
The stapler is divided into two separable parts: a reusable handle and a disposable adapter. The adapter can be detached from the handle after use, allowing the handle to be sterilized and reused while the adapter is discarded. This segmentation resolves the contradiction by enabling the handle to be sterilized properly while eliminating the sterilization problem of the adapter through disposal.
Solution Approach 2:
The adapter is extracted as a separate disposable component from the handle system. By removing the adapter as a distinct element that can be taken off and discarded, the handle can be fully sterilized and reused, while the adapter that cannot be sterilized is eliminated from the reusable portion of the system.
2Reliability
If a disposable endoscopic cutting stapler is used, then cross-infection risk is reduced, but the cost is higher and brings economic burden to patients
Solution Approach 1:
The stapler system is segmented into an expensive reusable handle and a cheaper disposable adapter. This allows the costly handle to be reused after sterilization, while only the less expensive adapter is discarded, thereby reducing overall treatment costs compared to completely disposable staplers while maintaining infection control.
Solution Approach 2:
The disposable adapter is discarded after single use to ensure infection control, while the valuable handle is recovered and sterilized for reuse. This selective discarding and recovery strategy reduces waste and lowers costs compared to discarding the entire stapler.
3Ease of operation
If a mechanical endoscopic cutting stapler is used, then operation is simple, but cutting stability is poor and firing force is low
Solution Approach 1:
The traditional mechanical operation system is replaced with an electric drive system. The electric motor provides more stable and powerful driving force for the cutter holder, improving cutting stability and firing force while maintaining ease of operation through automated control.

AI summary
Provided by the present invention is a reusable stapler comprising an adapter and a handle, the adapter being detachably connected to the handle. The adapter is a disposable component. The handle can be repeatedly used after being sterilized. The handle comprises a frame and an assembly/disassembly dial button, the assembly/disassembly button being mounted on the frame. The adapter comprises a center rod sleeve, the end of the center rod sleeve having a pair of bulges. The assembly/disassembly button is configured to control the detachable connection between the adapter and the handle. The handle can be repeatedly used after being sterilized, thereby reducing the surgery cost. The solution of detachable adapter provided by the present invention is reliable, simple, and convenient to operate, and can effectively implement the assembly and disassembly of the adapter.
