Abstract
Abstract A surgical smoke filter and evacuator and a surgical power generator of the type used for electrocautery, laser surgery or the like are combined with an enclosure between the generator and the evacuator. The enclosure directs air which has been filtered of surgical plume contaminants from the evacuator past heat sink elements associated with the generator to facilitate dissipation of heat accumulated incidental to operation of the generator.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
A system, comprising: an electrically operable surgical power generator including: (a) an encasement defining the interior of said generator; (b) fluid communication means formed in a base of said encasement for communicating fluid to said interior; (c) heat sink structure for transfer of heat generated by said generator away from said generator; and (d) heat vents formed in said encasement proximal said heat sink structure; a surgical plume evacuator including: (a) an electrically operable motor; (b) vacuum pump means driven by said motor and having a negative pressure port and a positive pressure port; (c) a surgical plume filter having a distal opening in fluid communication with said negative pressure port and having a proximal opening; and (d) a housing defining a space outside of which said proximal opening is located and inside of which said positive pressure port is located; and attachment means for securing said generator and said evacuator together, whereby said space and said base are in substantially fluid-tight relation except for said fluid communication means and said positive pressure port.
Claim 2
Independent Claim
174 words
A system, comprising: an electrically operable surgical power generator including: (a) an encasement defining the interior of said generator; (b) fluid communication means formed in a base of said encasement for communicating fluid to said interior; (c) heat sink structure for transfer of heat generated by said generator away from said generator; and (d) heat vents formed in said encasement proximal said heat sink structure; a surgical plume evacuator including: (a) an electrically operable motor; (b) vacuum pump means driven by said motor and having a negative pressure port and a positive pressure port; (c) a surgical plume filter having a distal opening in fluid communication with said negative pressure port and having a proximal opening; and (d) a housing defining a space outside of which said proximal opening is located and inside of which said positive pressure port is located; and attachment means for securing said generator and said evacuator together, whereby said space and said base are in substantially fluid-tight relation except for said fluid communication means and said positive pressure port.
