Disposable Surgical Handle With Pivot Button And Bore Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tools lack a quick and easy-to-use interface that can accommodate various prosthetic component configurations and ensure secure attachment and release, which is essential for efficient surgical procedures.
Innovation Solution
A disposable handle with a monolithic, bulbous design featuring a longitudinal and transverse bore system and a pivotably attached button, allowing for easy thumb or index finger operation to engage or disengage a surgical tool, providing a secure connection and simple manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick-release mechanism is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The handle is divided into distinct functional segments: a monolithic body portion and a separate tool-retaining assembly. The tool-retaining assembly includes a core member with locking elements that can independently engage or disengage from the body, allowing the surgical tool to be quickly attached or released without manipulating the entire handle structure.
Solution Approach 2:
The locking mechanism is extracted as a distinct functional component within the tool-retaining assembly. The locking elements are separate features on the core member that can engage with corresponding features on the body, allowing the release function to be isolated and simplified rather than integrated into the entire handle structure.
2Ease of manufacture
If a reusable assembly is used, then the manufacturing cost is reduced, but the reliability decreases due to wear and sterilization degradation
Solution Approach 1:
The handle is designed as a disposable, single-use device that is discarded after one surgical procedure. This eliminates the need for repeated sterilization cycles that can degrade reusable devices, ensuring consistent performance and reliability. The monolithic construction simplifies manufacturing while maintaining cost-effectiveness for single-use applications.
3Manufacturing precision
If a monolithic construction is used, then the manufacturing precision is improved, but the adaptability decreases
Solution Approach 1:
The core member is designed with a universal interface that can accommodate various surgical tool configurations. The longitudinal bore and transverse bore with locking elements create a standardized connection system that can securely hold different types of surgical components while maintaining the simplicity of monolithic body construction.

AI summary
An apparatus for releasably holding a surgical tool having a body, the body having a longitudinal axis, a monolithic construction, and a shape apportioned to be grasped by a human hand, with body further having a tool engaging portion, a hand receiving portion, and a button pressing portion. A longitudinal bore is disposed along the longitudinal axis of the body, and on one end. A transverse bore is disposed through the body into the longitudinal bore, with the transverse bore disposed such that the longitudinal axis of the transverse bore intersects the longitudinal axis of the longitudinal bore. A button disposed on and pivotably attached at a resilient member to the button pressing portion of the exterior of the body, with the button being proximal to the tool engaging portion. The button has a button bore and a boss extending from the button bore into the transverse bore which is alignable with the longitudinal bore. The button is disposed on the body to be thumb pressable, the button suitable for selectively engaging a corresponding groove on surgical tool.
