Solution Overview

Problem

Existing medical forceps used in spinal screw rod fixation operations lack the ability to efficiently switch between opening and pressurizing functions, leading to complex operations and increased medical costs due to the need for multiple tools.

Innovation Solution

A dual-purpose forceps design featuring a pair of forceps bodies connected via an articulated shaft, allowing seamless switching between opening and pressurizing functions through engagement and disengagement of specific connection members, with non-circular hinge designs and wear-resistant layers to enhance functionality and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate forceps are used for opening and pressurizing functions, then functional specialization is improved, but device complexity and medical cost increase

Engineering Contradiction:

Improvefunctional specializationVSAvoidnumber of forceps

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines opening function members and pressurizing function members into a single forceps body, allowing both functions to be integrated in one device. The forceps body includes both opening function members extending from the handheld member and pressurizing function members, eliminating the need for multiple separate forceps while maintaining functional specialization

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The forceps body is designed as a universal tool that can perform both opening and pressurizing functions. By incorporating both opening function members and pressurizing function members in the same forceps body, the device achieves multi-functionality, allowing surgeons to switch between operations without changing tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate forceps are used for opening and pressurizing functions, then functional specialization is improved, but ease of operation deteriorates due to switching between tools

Engineering Contradiction:

Improvefunctional specializationVSAvoidoperational complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The forceps body can dynamically switch between opening and pressurizing functions by selectively engaging different function members. The articulated shaft allows the forceps to adapt its configuration based on the required function, enabling smooth transitions between operations without retooling

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If a dual-purpose forceps is designed with switching capability, then device complexity increases, but adaptability improves

Engineering Contradiction:

Improvefunction switching capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The forceps body is segmented into distinct functional modules: opening function members and pressurizing function members. Each module can be independently engaged or disengaged, allowing the device to switch functions without requiring a completely redesigned structure. The articulated shaft connects these modules, enabling flexible configuration

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The articulated shaft serves as an intermediary mechanism that enables function switching between opening and pressurizing modes. By rotating or articulating the shaft, the forceps can selectively engage different function members, providing a simple mechanical means to switch functions without complex control systems

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invention provides a pair of dual-purpose forceps, comprising a first forceps body and a second forceps body. When the first forceps body is connected with the second forceps body by means of a first pressurizing connecting member and a second pressurizing connecting member, a first handheld member and a second handheld member move towards each other, and a first pressurizing functional member and a second pressurizing functional member also move towards each other to complete pressurizing; when the first forceps body is connected with the second forceps body by means of a first opening connecting member and a second opening connecting member, the first handheld member and the second handheld member move towards each other, and a first opening function member and a second opening function portion face away from each other to complete opening. The dual-purpose forceps is simple in structure and is operated conveniently so that the double-purpose forceps can switch freely between opening and pressurizing functions conveniently and quickly.
