Surgical Stapling Device Dissecting Tip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical stapling devices require additional tools and steps to separate adherent tissue from target tissue during procedures, making them time-consuming and costly, especially in endoscopic procedures.
Innovation Solution
A dissecting tip is integrated into the surgical stapling device, which can be attached to the anvil or cartridge assembly, featuring a curved or flat design with a rounded tip to safely separate adherent tissue from target tissue, allowing for simultaneous tissue joining and cutting without the need for separate instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate instrument and guide tube are used to dissect adherent tissue from target tissue, then tissue separation can be achieved, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The patent integrates a dissecting tip directly onto the anvil assembly of the surgical stapling device, combining the tissue dissection function with the existing stapling device. This eliminates the need for separate dissection instruments and guide tubes, thereby reducing procedural complexity while maintaining reliable tissue separation capability.
Solution Approach 2:
The surgical stapling device is enhanced with multi-functionality by incorporating a dissecting tip that enables both tissue dissection and stapling operations with a single device. The dissecting tip can separate adherent tissue from target tissue, while the anvil assembly performs staple formation, eliminating the need for multiple specialized instruments.
2Reliability
If additional separate instruments and guide tubes are used for tissue dissection, then adherent tissue can be separated, but procedural time increases
Solution Approach 1:
By integrating the dissecting tip onto the anvil assembly, the patent enables tissue dissection and stapling to be performed in a single procedural sequence without requiring separate instruments or additional setup time for guide tubes, thereby reducing overall procedural time while maintaining effective tissue separation.
Solution Approach 2:
The dissecting tip is pre-positioned on the anvil assembly, allowing tissue dissection to be performed immediately upon device insertion without requiring separate preparation steps or additional instrument introduction, thus eliminating time loss associated with sequential instrument deployment.
3Reliability
If multiple separate devices are used for dissection and stapling, then specialized functions are achieved, but cost increases
Solution Approach 1:
The patent combines the dissection function and stapling function into a single integrated device. The dissecting tip is attached to the anvil assembly, allowing both tissue separation and staple formation to be performed with one device, thereby reducing the number of required instruments and associated costs while maintaining specialized functionality.
Solution Approach 2:
The surgical stapling device achieves multi-functionality by incorporating a dissecting tip that provides specialized tissue separation capability alongside the standard stapling function. This eliminates the need for multiple specialized devices, reducing overall procedural cost while maintaining reliable adherent tissue separation.

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 the surgical instrument, e.g., to the 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.
