Surgical smoke field evacuators
View Patent ↗Universally adaptable evacuators are adaptable to all surgical fields, easy to apply and, in most cases, may be expanded and/or removed as necessary. A hollow tube including a fitting adapted for connection to a vacuum source and at least one smoke inlet is held in position with the smoke inlet proximate to a surgical wound. According to a preferred embodiment, a stapling tab extending from a flexible perforated tube is used to hold the evacuator in place around the periphery of a surgical incision. According to an alternative embodiment, a smoke evacuator attaches temporarily or permanently to a retractor or other surgical instrument. Standard tubing and couplers may be used and the assembly may be prepackaged in sterile condition and disposed after use.
1. A surgical field smoke evacuator, comprising:
a hollow, flexible tube having a proximal end with a fitting adapted for connection to a vacuum source and a distal end that branches into a pair of side tubes, each side tube having a plurality of smoke inlets;
the side tubes being composed of modular, interconnectable sections; and
at least one element for holding the side tubes in position with the smoke inlets proximate to a surgical wound.
2. The surgical field smoke evacuator of claim 1 , wherein the element is a stapling tab extending from the hollow, flexible tube.
3. The surgical field smoke evacuator of claim 1 , wherein the side tubes rejoin distally after the branching.
4. The surgical field smoke evacuator of claim 1 , wherein the modular, interconnectable sections are of varying lengths to accommodate different incision dimensions.
