Surgical Patch Collection Device for Pathogen Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Minimal invasive surgical procedures face the challenge of pathogen dispersal through insufflating gases leaking from cavities during procedures, posing risks to healthcare personnel and necessitating a solution to minimize the release of pathogens and particulate matter into the environment.
Innovation Solution
A collection device comprising a patch with a flexible peripheral membrane and a securing means to form a collection chamber around the access device, coupled with a vacuum system to draw and filter insufflating gases, effectively capturing and removing pathogens and other matter before they escape into the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If minimal invasive surgical procedures are performed using trocars and insufflating gas, then recovery time is significantly shortened compared to open surgery, but pathogens and particulate matter leak into the environment through the incision and instrument bore
Solution Approach 1:
A collection device acts as an intermediary between the insufflated cavity and the external environment. This device includes a collection chamber that captures insufflating gas leaking through the incision, and a filter that removes pathogens and particulate matter before gas is discharged to the environment, thus resolving the contradiction between maintaining minimal invasive benefits and preventing pathogen dispersal
Solution Approach 2:
The harmful components (pathogens and particulate matter) are extracted from the insufflating gas through filtration. The collection device separates the useful insufflating gas from the harmful contaminants, allowing the gas to be discharged while the pathogens are retained and disposed of safely
2Object-generated harmful factors
If a collection device with filter is added to the surgical system, then pathogen dispersal is minimized, but device complexity increases
Solution Approach 1:
The collection device is designed to be adaptable to different access devices (trocars, endoscopes, colonoscopes) and can be used in various minimal invasive procedures. The same basic structure with collection chamber and filter serves multiple functions: capturing leaking gas, filtering pathogens, and safely discharging filtered gas, thus reducing the need for multiple specialized devices
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces the dispersal of pathogens and particulate matter, ensuring a safer environment for healthcare personnel by collecting and filtering insufflating gases, thereby minimizing the risk of infection and maintaining a clean environment during procedures.
Implementation Method 1
an outlet port is provided extending from the patch communicating with the collection chamber, the outlet port being adapted for coupling to a vacuum generating system for drawing gas from the collection chamber

AI summary
A collection device (1) for minimising dispersal of pathogens into the environment during insufflating of the peritoneal cavity (12) of a subject (3), and which are entrained in insufflating gases and other gases escaping through an incision (8) in the abdominal wall (9) of the subject (3), through which a trocar is entered into the peritoneal cavity (12) comprises a patch (5) supported on a support framework (30). The patch (5) terminates in an outer peripheral portion (20) with a pressure sensitive adhesive (21) coated thereon for sealably securing the outer peripheral portion (20) to the abdominal wall (9). A central access opening (24) formed in the patch (5) tightly and sealably engages the trocar (10). With the trocar (10) extending through the access opening (24) of the patch (5) and with the patch (5) bonded by the pressure sensitive adhesive (21) to the abdominal wall (9) of the subject, the patch (5) defines with the trocar (10) and the abdominal wall (9) of the subject an annular collection chamber (17) for collecting insufflating and other gases leaking through the opening (8) in the subject. An outlet port (25) extending from the patch (5) and communicating with the collection chamber (17) is connected through a filter (29) to a vacuum system (27) for drawing gases from the collection chamber (17) where they are filtered in the filter (29) for removing pathogens therefrom, and clean filtered gases are dispersed into the atmosphere from the vacuum system (27). Other access devices and apparatus for collecting and filtering insufflating gases and other gases leaking through an incision formed in the body of a subject or through other body orifices are also disclosed.
