Rotational Needle Driver Ergonomic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical suturing devices lack an ergonomic and rotational mechanism that allows for precise control and reduced handedness, leading to inefficiencies and increased risk of damaging tissues during suturing procedures, especially in deep and restricted areas.
Innovation Solution
A surgical suturing needle driver with an ergonomic handle and rotational mechanism that secures the needle, allowing for precise angle control and reduced wrist motion, thereby simplifying the suturing process and minimizing tissue damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional needle driver design is used, then the suturing procedure can be performed, but the device lacks ergonomic features and rotational control, leading to increased complexity of maneuvers and higher risk of tissue damage
Solution Approach 1:
The needle driver incorporates a rotational mechanism that allows the needle to be rotated relative to the driver body, enabling dynamic adjustment of needle orientation during the suturing procedure. This dynamic feature simplifies complex maneuvers by allowing the surgeon to rotate the needle into the desired position rather than performing multiple complex wrist movements.
Solution Approach 2:
The needle driver is divided into distinct functional segments: a handle portion, a shaft portion, and a needle retention mechanism. The needle can be independently rotated within the retention mechanism, separating the rotation function from the overall driver operation and reducing the complexity of manual maneuvers required.
2Measurement precision
If precise angle control is implemented through rotational mechanism, then needle placement control is improved, but the device structure becomes more complex
Solution Approach 1:
The rotational mechanism provides dynamic angle adjustment capability, allowing the needle to be positioned at precise angles relative to the driver shaft. The rotation is achieved through a simple mechanism that converts rotational motion into precise angular positioning without requiring complex control systems.
Solution Approach 2:
The needle retention mechanism includes features that automatically maintain the needle at the desired angle once positioned. The rotational mechanism allows the surgeon to set the angle, and the mechanism itself maintains that positioning through its structural design, reducing the need for continuous active control.
3Reliability
If the needle is securely fixed to the needle driver, then control over needle movements is improved, but the mechanism for securing and rotating the needle becomes more complex
Solution Approach 1:
The needle retention mechanism provides dynamic securing and rotation capability. The needle can be firmly held in position when needed, yet easily rotated when angle adjustment is required. This is achieved through a mechanism that combines secure retention with controlled rotational movement.
Solution Approach 2:
The needle retention mechanism combines multiple functions into a single integrated structure: needle holding, needle rotation, and angle maintenance. By merging these functions into one mechanism rather than separate systems, the overall complexity is reduced while maintaining reliable needle fixation and control.

AI summary
A rotational action needle driver that comprises an cumbersome ergonomically designed handle, rotational mechanism and an integrated locking/unlocking system that permits surgeons to perform the surgical suturing procedure in a less complicated and more secure way by allowing more control over the suturing needle and the area to be stitched, even when the suturing area is small, deep, and/or restricted.
