Abstract

A smoke evacuation system is provided for attachment to a surgical desiccator, the surgical desiccator including a desiccator body forming a handle and a cauterizing tip for searing tissue to reduce bleeding. The smoke evacuation system includes a section of tube connected to a suction unit, a front retainer and a rear retainer for holding the tube to the body in a position such that the tube and the desiccator body can be cradled in a surgeon'"'"'s hand, and a suction tip attachable to the front retainer in a non-interfering position proximate the cauterizing tip. The front retainer defines a passageway connecting the suction tip to the section of tube such that smoke, odors and biological contaminants generated by the cauterizing tip can be efficiently suctioned away through the suction tip, the retainer and the tube by the suction unit. The front retainer releasably engages suction tips for easy replacement of the suction tips for sterility and so that a particular suction tip can be selected to correspond to a particular cauterizing tip. The front retainer comprises two halves which define a first recess therebetween for supporting a nipple to engage the section of tube, a second recess therebetween for supporting an insert to engage the desiccator, and a third recess therebetween defining a passageway between the suction tip and the section of tube for placing the suction tip and the section of tube in gaseous communication. A desiccator incorporating the section of tube and utilizing the suction tips is also disclosed.

4. A smoke evacuation system a defined in claim 1 wherein said retainer includes insert retaining surfaces, and including an insert shaped to mateably engage a front end of the desiccator body and to be securely supported by said insert engaging surfaces.

5. A smoke evacuation system as defined in claim 1 including a plurality of said suction tips, said suction tips each being configured to releasably engage said retainer.

6. A smoke evacuation system as defined in claim 1 including a second retainer spaced frown said first retainer, said second retainer being configured to engage the desiccator body and to hold said elongated member adjacent the desiccator body.

7. A smoke evacuation system as defined in claim 1 wherein said retainer includes nipple supporting surfaces, and including a nipple positioned and secured to said retainer by said nipple engaging surfaces, said nipple being configured to engage said elongated member.

10. A smoke evacuation system as defined in claim 1 wherein said retainer includes material defining a first aperture for releasably receiving and holding said suction tip, material defining a second aperture for receiving a nipple to engage said elongated member, material defining a passageway placing said first and second passageways in communication, and material defining a third aperture for receiving an insert to securely engage a front end of the desiccator body.

8. A smoke evacuation system for attachment to a surgical desiccator, comprising:

an elongated member defining a first passageway including an outlet configured for attachment to a suction unit;

a suction tip defining a second passageway including an inlet;

a first retainer configured to secure said elongated member and said suction tip to a desiccator with said elongated member being positioned generally adjacent a body of the desiccator and said suction tip inlet being positioned proximate a cauterizing tip of the desiccator, said retainer defining an airtight intermediate passageway placing said first and second passageways in communication so that, by suctioning air from said elongated member outlet, air is drawn into said suction tip inlet along with smoke, odors and biological contaminants generated by the cauterizing tip, said first retainer defining a hole configured to mateably engage a front nose of the desiccator body along a longitudinal direction defined by the hole;

said intermediate passageway extending generally transversely to said longitudinal direction and extending circumferentially, partially around the hole; and

a second retainer spaced from said first retainer configured to engage and hold said elongated member adjacent the body of the desiccator, said second retainer including a pair of opposing half sections and a hinge connecting said opposing half sections.

9. A smoke evacuation system for attachment to a surgical desiccator, comprising:

an elongated member defining a first passageway including an outlet configured for attachment to a suction unit;

a suction tip defining a second passageway including an inlet; and

a retainer configured to secure said elongated member and said suction tip to a desiccator with said elongated member being positioned generally adjacent a body of the desiccator and said suction tip inlet being positioned proximate a cauterizing tip of the desiccator, said retainer defining an airtight intermediate passageway placing said first and second passageways in communication so that, by suctioning air from said elongated member outlet, air is drawn into said suction tip inlet along with smoke, odors and biological contaminants generated by the cauterizing tip, said retainer including an aperture configured to mateably engage a front nose of the desiccator along a longitudinal direction defined by the aperture, said retainer including mating half sections that can be secured together along said longitudinal direction to define said intermediate passageway.

11. A smoke evacuation system for attachment to a surgical desiccator, comprising:

an elongated member defining a first passageway including an outlet configured for attachment to a suction unit;
