Solution Overview

Problem

Existing puncture devices lack real-time imaging assistance, leading to reduced accuracy and smoothness in puncture processes due to manual operation and exposure to radiation.

Innovation Solution

A puncture device with a puncture needle mechanism, mobile mechanism, and clamping mechanism, allowing remote operation and real-time imaging assistance, enhancing accuracy and safety by minimizing direct exposure to radiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the operator directly controls the puncture instrument by hand, then the operator can perform the puncture operation, but the operator cannot obtain real-time imaging assistance and is exposed to radiation

Engineering Contradiction:
Improvepuncture accuracyVSAvoidradiation exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a mechanical arm as an intermediary between the operator and the puncture instrument. The mechanical arm includes a puncture executing mechanism that can be remotely controlled, allowing the operator to perform puncture operations without direct hand control. This intermediary device enables real-time imaging assistance through imaging devices positioned at the puncture site while protecting the operator from radiation exposure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the operator directly controls the puncture instrument, then the operation can be performed, but the puncture accuracy and smoothness are limited due to lack of real-time imaging

Engineering Contradiction:
Improvepuncture location accuracyVSAvoidoperation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces the direct manual mechanical control system with a remote control system. The mechanical arm is controlled through a control mechanism that can be operated from a distance, substituting the operator's direct hand control. This allows real-time imaging devices to be positioned at the puncture site for accurate visualization and guidance, improving puncture location accuracy while reducing operational complexity through automated positioning and control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
