Solution Overview

Problem

Conventional microsurgery clip application devices require manual loading of individual clips, leading to handling accidents, inefficiencies, and the need for multiple forceps, which complicates surgical procedures.

Innovation Solution

A surgical clip application device with automatic clip loading, allowing multiple clips to be applied sequentially, featuring a clip loader assembly, drive mechanism, and transparent window for clip count visibility, along with multiple touch points and gripping surfaces for ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual loading of individual clips is used, then device complexity is reduced, but productivity decreases and handling accidents increase

Engineering Contradiction:
Improveclip application efficiencyVSAvoiddevice structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple surgical clips are pre-loaded into the device reservoir before the surgical procedure begins. The clips are arranged in a stacked configuration within the reservoir, ready for sequential dispensing without requiring manual intervention during the surgery. This preliminary loading action eliminates the need for repeated manual clip loading during the procedure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device incorporates an automatic clip dispensing mechanism that self-regulates the delivery of clips during the surgical procedure. When the operator activates the dispensing mechanism, the system automatically selects, positions, and delivers the next clip from the reservoir without requiring manual handling or reloading by the surgical professional.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple forceps are used for clip application, then clip application capability is improved, but device complexity and maintenance requirements increase

Engineering Contradiction:
Improveclip application capabilityVSAvoidnumber of forceps required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device integrates multiple functions into a single instrument: it serves as both the forceps for applying clips and the reservoir for storing multiple clips. The unified design combines the clip application mechanism with an integrated reservoir that holds multiple clips in a stacked arrangement, eliminating the need for separate forceps and clip storage systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the clip storage reservoir and the clip application forceps into a single integrated device. The reservoir is positioned within the handle structure, and the dispensing mechanism combines the functions of clip selection, positioning, and delivery in one unified system, reducing the number of separate instruments required.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of time

If manual clip reloading is performed, then device complexity is reduced, but loss of time increases due to repeated reloading actions

Engineering Contradiction:
Improvetime for clip reloadingVSAvoidautomatic loading mechanism
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The device enables continuous clip application without interruption for reloading. Multiple clips are stored in the reservoir in a ready-to-dispens e configuration, allowing the surgeon to continuously apply clips to different vessels without stopping the surgical flow to reload individual forceps. The automatic dispensing mechanism maintains continuous operational readiness.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Multiple clips are pre-loaded into the reservoir before the surgical procedure begins, with each clip positioned and ready for sequential dispensing. This preliminary preparation eliminates the need for time-consuming manual reloading actions during the procedure, as clips are automatically delivered from the pre-configured reservoir.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles
