Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical puncture device insertion systems lack effective methods for guiding the insertion of puncture devices through patient tissue to access internal patient cavities, often relying on manual manipulation and lacking real-time feedback to ensure safe and precise puncture creation.
Innovation Solution
A medical puncture system that includes a puncture device, a sensor, and an indicator system, where the sensor generates signals indicative of the motion of the puncture device through tissue, and the indicator system provides human-perceptible feedback to guide the creation of the puncture, or autonomously controls the movement of the puncture device to ensure safe insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual manipulation is used for puncture device insertion, then operator flexibility is maintained, but real-time feedback and precision are insufficient
Solution Approach 1:
The patent implements sensor systems that detect puncture device position, tissue impedance, and force applied during insertion. This feedback is processed by a controller that provides real-time guidance to the operator through visual or haptic interfaces, enabling precise puncture positioning while maintaining operator control and flexibility.
Solution Approach 2:
The patent introduces a controller as an intermediary between the operator and the puncture device. The controller receives sensor data, processes it according to safety parameters and target coordinates, and provides guidance signals to the operator, thereby enhancing precision without requiring direct complex automation of the insertion mechanism.
2Reliability
If automated control is implemented for puncture device movement, then insertion precision is improved, but operator control and adaptability are reduced
Solution Approach 1:
The patent implements partial automation where the controller provides guidance signals and safety monitoring, but the operator maintains final control over the puncture device insertion. The system automates specific functions such as position tracking and safety parameter monitoring while leaving adaptive decision-making to the operator, achieving enhanced reliability without sacrificing operational ease.
3Manufacturing precision
If real-time sensor feedback is provided during insertion, then puncture accuracy is enhanced, but system complexity and cost increase
Solution Approach 1:
The patent divides the sensor system into modular components: position sensors, force sensors, and impedance sensors, each providing specific feedback. The controller processes these segmented data streams independently and integrates them into comprehensive guidance, enabling precise puncture creation while managing system complexity through functional segmentation.
4Object-affected harmful factors
If the puncture device is manually inserted without guidance, then system simplicity is maintained, but the risk of human error and unsafe insertion increases
Solution Approach 1:
The patent implements preliminary action by pre-programming safety parameters, target coordinates, and insertion pathways before the procedure begins. The controller compares real-time sensor data against these pre-established parameters, providing proactive guidance and alerts before unsafe conditions occur, thereby reducing insertion risks without requiring complex real-time decision algorithms.

AI summary
A medical puncture device system includes a puncture device, a sensor, and an indicator system. The puncture device is configured to create a puncture through patient tissue and into an internal patient cavity to enable a medical tool to be inserted through the puncture into the cavity. The sensor is configured to generate a signal indicative of motion of the puncture device through the tissue into the cavity. The indicator system is operable by a controller to produce human-perceptible feedback in response to the signal generated by the sensor.
