Abstract

Most suction irrigation devices are configured to have separate fluid paths for each mode. In regards to the suction path, tissue can get stuck inside the device or suction tube, preventing additional operation of the suction. Being able to introduce fluid to help move a clog or aid a large bolus of tissue out of the manifold and into the suction tube would be beneficial.

Geometry

Summary

Most suction irrigation devices are configured to have separate fluid paths for each mode. In regards to the suction path, tissue can get stuck inside the device or suction tube, preventing additional operation of the suction. Being able to introduce fluid to help move a clog or aid a large bolus of tissue out of the manifold and into the suction tube would be beneficial.

Description

This solution involves the ability to clear a clog by using irrigation.

There could be configuration where a medical suction / irrigation device utilizes a common chamber co-configuring the fluid path for both suction and irrigation. To accomplish this would require managing the irrigation flow to direct it towards the clog to aid in the flushing.

The device would be set up with a diverter plate that can be deployed to shutoff the common suction/irrigation opening distal to the irrigation fluid path, which would leave the proximal suction path open, the main path to exit. Depressing both buttons creates not only suction force, but also draws the fluid directly into the common chamber, loosening the bolus of tissue, allowing the irrigation fluid to help flush out the clog in the suction line.
