Surgical Insertion Handle With Pivotable Implant Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tools lack precise control and versatility for inserting medical implants, particularly in less-invasive procedures where smaller surgical openings require more angular manipulation of implants during orthopedic surgeries.
Innovation Solution
A surgical insertion handle with a pivotable connection mechanism that allows for angular positioning and locking of medical implants relative to the handle axis, enabling rotation and adjustment of the implant's orientation during insertion through a combination of an actuator, pivot member, and attachment screw, facilitating precise placement through smaller surgical openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surgical tools are used for implant insertion, then the surgical opening can be kept simple, but precise control and angular manipulation of implants are insufficient
Solution Approach 1:
The surgical tool is divided into multiple functional segments: an outer shaft for insertion, an inner control shaft for angular manipulation, a pivotable connection mechanism for orientation control, and an actuator system for driving movements. This segmentation allows each component to perform a specific function, achieving precise control while keeping the overall system manageable through modular design
Solution Approach 2:
The connection mechanism between the outer shaft and inner control shaft is designed to be pivotable rather than fixed, allowing dynamic angular adjustment during implant insertion. The actuator system enables controlled rotation and positioning of the inner shaft relative to the outer shaft, providing real-time adaptability for precise implant placement through smaller openings
2Object-affected harmful factors
If smaller surgical openings are used to reduce patient trauma, then patient recovery is improved, but control over implant manipulation and orientation is reduced
Solution Approach 1:
The tool design adds rotational and angular dimensions to the insertion process through the pivotable connection mechanism and actuator system. This allows the surgeon to manipulate the implant orientation in multiple degrees of freedom while accessing through a constrained, small opening, effectively transforming a linear insertion problem into a multi-dimensional positioning solution
Solution Approach 2:
The inner control shaft acts as an intermediary between the surgeon's manual input and the implant itself. It transmits and transforms rotational movements from the actuator into precise angular adjustments of the implant orientation, enabling fine control through a small surgical opening without requiring direct manual manipulation of the implant
3Adaptability or versatility
If fixed-angle implant insertion is used, then the insertion process is simpler, but versatility for different angular positions is limited
Solution Approach 1:
The actuator system is designed to provide multiple functions: it can rotate the inner control shaft to different angles, lock the shaft at selected angles, and maintain positioning during implant insertion. This multi-functionality allows a single device to handle various implant orientations and surgical scenarios, achieving versatility without proportionally increasing complexity

AI summary
An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.
