Solution Overview

Problem

Current surgical stapling devices require separate tools and procedures to access and separate adherent tissue from target tissue, making them time-consuming and costly, especially during endoscopic procedures.

Innovation Solution

A surgical stapling device with a dissecting tip that can be integrated into the end effector, featuring various configurations such as curved or flat surfaces, allowing for tissue separation while maintaining access and visibility, reducing the need for additional tools and simplifying the procedure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate devices are used to dissect tissue before stapling, then tissue separation can be achieved, but procedural time and cost increase

Engineering Contradiction:

Improvetissue separation capabilityVSAvoidprocedural time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the dissecting tip and stapling function into a single integrated device. The dissecting tip is mounted on the end effector of the stapling device, allowing both tissue separation and stapling to be performed by one instrument rather than requiring separate devices, thereby reducing procedural time while maintaining reliable tissue separation capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stapling device is designed with multi-functionality by incorporating a dissecting tip that can separate adherent tissue, plus the standard stapling and cutting functions. This universal design allows a single device to perform multiple surgical tasks that previously required separate specialized instruments

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate devices are used to dissect tissue before stapling, then tissue separation can be achieved, but procedural cost increases

Engineering Contradiction:

3Productivity

If a dissecting tip is added to the stapling device, then tissue separation is integrated into the stapling process, but device complexity increases

Engineering Contradiction:

Improvesurgical efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The dissecting tip is designed as a separate, modular component that can be attached to or removed from the end effector. This segmentation allows the basic stapling device to remain simple while the dissecting functionality can be added only when needed, reducing overall device complexity while maintaining surgical efficiency

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dissecting tip is configured to be movable relative to the end effector, allowing it to be positioned as needed for tissue separation and then retracted or removed. This dynamic design allows the device to adapt its complexity based on procedural requirements rather than always being in a complex state

Inventive Principle:

Principle #15Dynamics

AI summary

A dissecting tip is provided for use with a surgical stapler or instrument. In one embodiment, the dissecting tip is secured to the end effector of a surgical stapler, e.g., to the anvil assembly or cartridge assembly. The dissecting tip extends distally from the end effector and is configured to dissect or separate target tissue from certain tissue, e.g., adherent, connective, joined or other tissue.
