Single-Hand Hemostatic Clip Handle for Physician Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hemostatic clips require assistance from support staff for precise application, leading to potential miscommunication and increased time in achieving hemostasis during gastrointestinal bleeding, which is a critical and invasive condition.

Innovation Solution

A physician-controlled single hand-operated handle system that allows for independent control over the rotation, opening, closing, and deployment of hemostatic clips, featuring a handle with an actuator, stem, sheath, and elongate member, enabling single-handed operation without support staff intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a physician relies on support staff to assist in the orientation to obtain the desired position of the device, then the device can be positioned accurately, but the time to obtain hemostasis increases and miscommunication may occur

Engineering Contradiction:

Improvepositioning accuracyVSAvoidtime to obtain hemostasis

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The handle assembly is designed to be self-operating, allowing the physician to independently control the elongate member's positioning, rotation, and actuation without requiring support staff assistance. The thumbwheel mechanism enables single-handed operation for precise positioning and deployment.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The control functions are integrated into a unified handle assembly that combines positioning, rotation, and actuation controls in one device, eliminating the need for multiple operators and reducing communication overhead.

Inventive Principle:

Principle #33Homogeneity

2Measurement precision

If a physician relies on support staff to assist in the orientation to obtain the desired position of the device, then the device can be positioned accurately, but communication errors may occur

Engineering Contradiction:

Improvepositioning accuracyVSAvoidcommunication reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

3Ease of operation

If a single hand operated handle system is used, then the physician can operate independently without support staff, but the device complexity increases

Engineering Contradiction:

Improveindependence of operationVSAvoidhandle system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Multiple control functions (positioning, rotation, actuation) are merged into a single integrated handle assembly, allowing the physician to operate the device independently while managing complexity through functional integration rather than separate components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handle assembly serves multiple functions through its integrated design, including positioning control via thumbwheel, rotation control, and actuation triggering, all within a single operational interface that reduces the need for multiple specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present disclosure relates to a physician controlled single hand operated handle system. The system includes a handle. The handle includes an actuator, a stem disposed within the actuator and longitudinally movable within the actuator, a sheath attached to the stem, and an elongate member extending through the sheath. The elongate member is longitudinally constrained by the actuator and rotatably constrained by the stem.
