Integrated Surgical Insufflation Device for Tube-Free Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical insufflation systems for vessel harvesting procedures are cluttered with large OR-provided gas tanks, insufflator machines, and tubes, leading to increased complexity, entanglement, and infection risks in the sterile field.
Innovation Solution
A surgical device with integrated canisters of pressurized insufflation media, such as CO2, eliminates the need for external tanks and tubes by incorporating a canister connection point and dispersion mechanism for controlled media release directly from the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional insufflation systems use external gas tanks and tubes, then sufficient insufflation media can be delivered, but the sterile field becomes cluttered and entanglement risk increases
Solution Approach 1:
The patent integrates the insufflation media storage canister and delivery mechanism directly into the EVH device handle, merging previously separate components (external gas tank, insufflator machine, and surgical device) into a single integrated unit. This eliminates the need for external tubing and reduces sterile field clutter while maintaining sufficient insufflation media delivery capability.
Solution Approach 2:
The patent extracts the insufflation media delivery function from the external OR equipment and incorporates it directly into the EVH device itself. The canister and dispersion mechanism are built into the device, removing the need for separate external gas tanks and tubing connections in the sterile field.
2Quantity of substance
If external tubes and wires are used for insufflation, then media delivery is established, but infection risk and procedural complexity increase
Solution Approach 1:
By integrating the canister and delivery mechanism into the EVH device, the patent eliminates external tubing connections that could introduce contaminants. The sealed integrated system reduces potential infection pathways while maintaining reliable insufflation media delivery to the surgical site.
3Quantity of substance
If conventional trocars are used for media delivery, then insufflation can be achieved, but accurate insertion becomes difficult
Solution Approach 1:
The patent combines the EVH device function with the insufflation media delivery function in a single integrated device. This eliminates the need for separate trocar insertion and subsequent tube connection steps, allowing accurate insertion of the EVH device itself while delivering insufflation media through its integrated canister and dispersion mechanism.

AI summary
The present invention provides systems, methods and devices for delivering media. The device can include a body designed to accommodate at least one cannister of a media, an body coupled to the body and having a distal end, and a tapered tip disposed at the distal end of the body and in fluid communication with the cannister, the tip being designed for advancing the distal end to a site of interest and through which media from the cannister can be directed to the site of interest. The device can also include a dispersion mechanism coupled to the body for controlled release of the media out the tapered tip.
