Abstract

An energy device that is combined with suction can lead to clogging within the device. The suction tube can easily become filled with a mix of saline, blood and tissue fragments to form a clog in the suction line. This clog could prevent a device from functioning properly. A device of this nature needs to prevent, avoid, and/or easily clear clogging for optimal use.

High Pressure Internal Fluid Line(s) in an Energy Device

Summary

Problem statement:

An energy device that is combined with suction can lead to clogging within the device. The suction tube can easily become filled with a mix of saline, blood and tissue fragments to form a clog in the suction line. This clog could prevent a device from functioning properly. A device of this nature needs to prevent, avoid, and/or easily clear clogging for optimal use.

One idea to clear clogging in the central lumen of the device is described below.

Description

An irrigation channel(s) will be along the inner surface of the blade. The channel will have multiple openings that allow the pressurized irrigation fluid to escape into the lumen of the blade. The opening(s) will be angled backwards with a single forward angled opening at the tip. The openings will be small and tapered, in order to facilitate a high pressure opening resulting in high velocity fluid streams. The high pressure fluid streams will be activated by the user if a clog is detected, and will supply force and lubrication to clear clogged material from the lumen. The high pressure fluid will come from its own irrigation line, and can include, but is not limited to compressed gas tanks, pressurized saline drip bags, or pumps.
