Anvil-Mounted Dissecting Tip for Surgical Stapling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical stapling devices require separate devices and additional steps to dissect or separate adherent tissue from target tissue, which is time-consuming and costly, especially during endoscopic procedures, as they typically only join and cut tissue.
Innovation Solution
A surgical stapling device with an anvil-mounted dissecting tip that allows for tissue separation when the jaw members are in an open position, enabling the device to dissect, join, and cut tissue simultaneously, improving accessibility and control during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate dissecting device is used to separate adherent tissue from target tissue, then tissue dissection can be performed, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The patent combines the dissecting tip with the anvil assembly to create a multi-functional surgical stapling device. The dissecting tip is integrated into the anvil assembly such that it can be used to separate adherent tissue from target tissue before stapling, eliminating the need for separate dissection devices and reducing procedural complexity.
Solution Approach 2:
The anvil assembly is designed to perform multiple functions: it forms staples during stapling and simultaneously serves as a mounting structure for the dissecting tip. This multi-functional design allows a single device to handle both tissue dissection and stapling operations, improving versatility while reducing the number of separate devices needed.
2Adaptability or versatility
If a separate dissecting device is used to separate adherent tissue, then tissue can be dissected, but the procedural time increases
Solution Approach 1:
By merging the dissecting tip with the anvil assembly, the patent enables tissue dissection and stapling to be performed in a single continuous operation. The dissecting tip is positioned to allow separation of adherent tissue before the stapling action, eliminating the need for separate dissection steps and reducing overall procedural time.
Solution Approach 2:
The dissecting tip is designed to perform preliminary tissue separation before stapling. By预先 separating adherent tissue from target tissue using the integrated dissecting tip, the device prepares the tissue for subsequent stapling in one continuous motion, eliminating the need for separate dissection steps and reducing overall procedural time.
3Adaptability or versatility
If a separate dissecting device is used, then tissue can be separated, but the procedural cost increases
Solution Approach 1:
The patent merges the dissecting tip with the anvil assembly to create a single integrated device that performs both dissection and stapling functions. This reduces the quantity of separate devices required during surgery, thereby lowering procedural costs associated with multiple disposable or reusable instruments.
Solution Approach 2:
The anvil assembly is designed as a universal component that performs both staple formation and tissue dissection. This multi-functionality reduces the need for multiple specialized devices, decreasing the overall quantity of equipment required and associated procedural costs.

AI summary
A surgical stapling device (10) including a handle assembly (16), an endoscopic portion (18) and an end effector (12) is disclosed. The endoscopic portion extends distally from the handle assembly and defines a first longitudinal axis. The end effector defines a second longitudinal axis and includes an anvil assembly (34) and a cartridge assembly (36). The anvil assembly is supported adjacent a distal end of the endoscopic portion and includes a dissecting tip (14) extending therefrom. The cartridge assembly is pivotably mounted adjacent the distal end of the endoscopic portion. The cartridge assembly is mounted for pivotal movement in relation to the anvil assembly between open and approximated positions.
