Solution Overview

Problem

Surgical guides for drilling into tissue, such as bone, require customization for specific procedures, which is time-consuming and costly, and existing solutions lack efficient adjustment mechanisms for precise angle control.

Innovation Solution

A surgical guide system with a drill guide that can adjust its angle relative to a base plane, transitioning between locked and unlocked states, using a locking nut and clamping mechanism, and an adjustment device with a handle and projection for precise angle setting, allowing for quick customization and reusability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If surgical guides are customized for specific procedures, then drilling precision is improved, but time consumption and cost increase

Engineering Contradiction:

Improvedrilling precisionVSAvoidtime consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The surgical guide is designed with a universal base that can accommodate multiple drill guides with different angles and configurations. The base includes a track system that allows different drill guides to be positioned and secured at various locations, enabling a single base to serve multiple surgical procedures rather than requiring custom guides for each procedure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The drill guide is designed with adjustable components including a movable body that can translate along the track and a rotatable mechanism that allows adjustment of the drill guide angle. The locking mechanism enables the drill guide to be fixed at specific angles during surgery, providing dynamic adjustability while maintaining stability during the actual drilling operation.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If surgical guides are customized for specific procedures, then drilling precision is improved, but cost increases

Engineering Contradiction:

Improvedrilling precisionVSAvoidcost

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The surgical guide system is divided into separate modular components including a base, drill guide body, locking mechanism, and track system. This segmentation allows the components to be manufactured independently using standard manufacturing processes, reducing the need for expensive custom fabrication while maintaining the ability to achieve precise drilling angles through the assembly of standardized parts.

Inventive Principle:

Principle #1Segmentation

3Stability of the object's composition

If drill guide angle is fixed, then stability is improved, but adaptability decreases

Engineering Contradiction:

ImprovestabilityVSAvoidadaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The surgical guide allows the drill guide angle to be adjusted and locked at the desired orientation before the drilling procedure begins. This preliminary adjustment and locking ensures that the optimal drilling angle is established in advance, providing both adaptability for different surgical requirements and stability during the actual drilling operation.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If adjustment mechanism is added, then adaptability is improved, but device complexity increases

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking mechanism is designed to be operated by the surgeon during the procedure, allowing the drill guide to be locked at the desired angle without requiring additional tools or complex adjustment procedures. The mechanism provides intuitive feedback and requires minimal操作步骤, reducing the effective complexity from the user's perspective.

Inventive Principle:

Principle #25Self-service

AI summary

A surgical guide includes a base and a drill guide coupled to the base. The drill guide includes a drill guide body defining a drill bore for receiving a drill bit and extending through the drill guide, the drill guide being configured to translate relative the base to adjust a drill guide angle defined by the drill bore and the base, the drill guide further being configured to transition between a locked state and an unlocked state, wherein the drill guide angle is fixed in the locked state and the drill guide angle is adjustable in the unlocked state.
