Insertion Device Visual Indicator for Needle Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an insertion device that facilitates the correct placement of implants within the body while preventing injury to surrounding tissues, such as the bladder, during surgical procedures for weakened or damaged anatomical tissues.
Innovation Solution
An insertion device with an elongate member featuring a needle portion and a handle portion, where the handle portion includes a visual indicator to indicate the orientation of the needle portion, aiding in precise placement and avoiding inadvertent damage to surrounding tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle portion is used to deliver the implant, then the implant can be delivered to the target location, but there is a risk of puncturing or injuring surrounding tissues such as the bladder
Solution Approach 1:
The patent incorporates visual indicators (such as windows, markers, or transparent portions) on the insertion device that provide real-time feedback to the operator about the needle's orientation and depth. This feedback mechanism allows the operator to monitor the needle trajectory and adjust the insertion angle to avoid surrounding tissues like the bladder, thereby reducing injury risk while maintaining reliable implant delivery.
Solution Approach 2:
The patent introduces an intermediary visual indicator system between the needle and the operator. These indicators (such as alignment markers, transparent sections, or colored portions) act as mediators that translate the invisible needle orientation into visible information, enabling the operator to make informed decisions about needle positioning to avoid harmful contact with surrounding tissues.
2Ease of operation
If the needle orientation is not visually indicated, then the device structure remains simple, but the operator cannot accurately control the needle trajectory
Solution Approach 1:
The patent utilizes color changes or color-coded visual indicators (such as colored markers, tinted windows, or colored portions of the handle) to indicate needle orientation. These color indicators provide intuitive visual feedback about the needle's angular position and trajectory, enabling easy control of the needle path without requiring complex mechanical guidance systems, thus balancing operational ease with device simplicity.
Solution Approach 2:
The patent divides the visual indicator system into separate, simple components (such as individual markers, discrete windows, or segmented colored portions) rather than using a single complex mechanism. This segmentation allows each indicator element to perform a specific function (showing angle, depth, or orientation) independently, maintaining overall device simplicity while providing comprehensive visual guidance for needle trajectory control.
