Implant Removal Tool Locking Interface for Fast Surgical Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection interfaces for implant removal tools in medical revision surgeries are time-consuming, require fine motor skills, risk cross-threading or misalignment, and have ergonomic limitations, hindering surgical efficiency and increasing the risk of disruption and harm.
Innovation Solution
A connection interface assembly with a handle, connection interface, and locking mechanism that allows for quick and secure engagement of implant removal tools through a movable locking mechanism, enabling selective engagement and disengagement via a retractable locking mechanism and complementary interface access regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connection interfaces are used for implant removal tools, then the tool can be connected to the handle, but the connection process is time-consuming and requires fine motor skills
Solution Approach 1:
The connection interface is divided into distinct components: a handle with a cavity, a connection interface with an interface access region, and a locking mechanism. This segmentation allows each component to perform its specific function independently, enabling quick and precise assembly without requiring fine motor skills for complex manual operations.
Solution Approach 2:
The locking mechanism automatically engages with the locking interface element when the implant removal tool is inserted into the connection interface. This self-locking feature eliminates the need for manual threading or complex fastening operations, significantly reducing connection time and improving ease of operation.
2Reliability
If traditional connection interfaces are used, then the tool can be attached to the handle, but there is risk of cross-threading or misalignment
Solution Approach 1:
The locking mechanism and locking interface element are designed with asymmetric geometries that only fit together in the correct orientation. This asymmetric design prevents cross-threading and misalignment by making incorrect assembly physically impossible, thereby eliminating the risk of harmful misalignment during surgical procedures.
Solution Approach 2:
The locking mechanism acts as an intermediary component between the handle and the implant removal tool. It provides a precise mating interface that guides the tool into correct alignment and secures it reliably, preventing misalignment and ensuring consistent, accurate connections during surgery.
3Productivity
If traditional connection interfaces are used, then the tool can be connected to the handle, but ergonomic limitations hinder surgical efficiency
Solution Approach 1:
The locking mechanism is designed to be movable between engaged and disengaged states, allowing dynamic adjustment during surgical procedures. This dynamic design enables surgeons to quickly attach and detach tools without struggling with static, difficult-to-operate connection interfaces, thereby improving ergonomic performance and surgical efficiency.

AI summary
In some implementations, a connection interface assembly may include a handle, a connection interface, a locking mechanism, and an implant removal tool. The handle may include a proximal end, a distal end, and a cavity including an interior surface. The distal end may define a distal end opening that is in communication with the cavity. The locking mechanism may be disposed within the cavity of the handle and may be movable between a projected position and a retracted position. The implant removal tool may include a first end and a second end. The second end may form a locking interface element. The implant removal tool may be selectively engageable with the connection interface via an engagement and disengagement between the locking mechanism and the locking interface element.
