Cannulated Implant Delivery With Dial-Based Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implant delivery systems lack the ability to adjust insertion depth accurately and provide precise measurement of implant length, leading to either fixed or freehand insertion methods that may not meet the surgeon's desired depth requirements.
Innovation Solution
A cannulated implant delivery device with a cannula and adjustable depth indicator, allowing for precise adjustment of insertion depth through a rotatable dial knob and depth markings, enabling measurement and cutting of implants to fit the desired depth range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed stopper is provided on the inserter device to allow insertion to a present fixed depth, then the insertion depth is controlled, but the adaptability to different surgeon preferences and tissue conditions is reduced
Solution Approach 1:
The depth indicator is made adjustable along the shaft of the inserter device, allowing the surgeon to dynamically reposition the indicator to any desired depth marking. This transforms a static fixed stopper into a dynamic adjustable mechanism, enabling adaptation to different surgical requirements while maintaining precise depth control through the graduated scale.
Solution Approach 2:
The device allows change in the positional parameter of the depth indicator along the shaft. The indicator can be moved to different locations corresponding to different insertion depths, enabling the surgeon to adjust the insertion depth parameter according to tissue conditions and surgical preferences while maintaining measurement precision through the graduated scale.
2Ease of operation
If the surgeon uses freehand insertion without depth indicators, then the ease of operation is improved, but the measurement precision of implant length and insertion depth is reduced
Solution Approach 1:
The depth indicator serves as an intermediary tool between the surgeon and the implant. It provides visual guidance and measurement reference during the insertion process, enabling precise measurement of implant length and insertion depth while maintaining ease of operation through simple visual alignment and marking functions.
Solution Approach 2:
The device creates a visual copy or representation of the implant's expected final position and length through the depth indicator and graduated scale. This allows the surgeon to measure and mark the implant to the correct length before insertion, ensuring measurement precision without complicating the actual insertion operation.
3Productivity
If the implant is inserted without pre-measurement and cutting, then the productivity is improved, but the manufacturing precision of implant length to match desired depth is reduced
Solution Approach 1:
The device enables preliminary measurement and marking of the implant to the correct length before insertion. The depth indicator allows the surgeon to determine the exact length needed and mark the implant accordingly, ensuring manufacturing precision is achieved prior to insertion while maintaining productivity by avoiding post-insertion adjustments.
Solution Approach 2:
The graduated scale on the depth indicator provides real-time feedback to the surgeon during the measurement process. This feedback mechanism allows precise determination of the required implant length based on the desired insertion depth, ensuring manufacturing precision while maintaining efficient workflow through quick and accurate measurement.

AI summary
A device, system and method for delivery of an implant having an adjustable length. The device is for inserting an implant at an appropriate tissue depth according to a depth finding placeholder, wherein the implant is suitable for insertion to a subject, the device comprising a cannula for receiving the depth finding placeholder and an adjustable depth of insertion element, wherein the adjustable depth of insertion element is adjusted to determine the appropriate tissue depth. The depth finding placeholder may include but is not limited to a wire, such as a K-wire for example. The cannula preferably comprises an opening of sufficient diameter to permit insertion of the depth finding placeholder. The cannula optionally comprises depth indicators, for example by being optionally marked with depth indicator markings. The device preferably comprises a transparent window, or optionally may comprise, additionally or alternatively, an open aperture and/or a viewing screen, to enable the depth indicators to be viewed.
