Systems and methods for optimizing and maintaining visualization of a surgical field during the use of surgical scopes

摘要

Systems and methods condition air for passage across a laparoscopic lens to prevent fogging, deflect debris, and maintain visualization of an operating cavity. The systems and methods provide an access device sized and configured to provide communication with an insufflated CO2 environment maintained by operation of an insufflations circuit. The access device is coupled to an air conditioning set, which interacts with an air conditioning driver to condition air from the insufflated environment for continuous passage across the laparoscopic lens, to thereby maintain visualization by the laparoscopic lens of the operating cavity, independent of operation of the insufflator circuit.

主权项

1. A surgical system for use with an insufflator circuit, the surgical system comprising:
a sheath sized and configured to receive a laparoscope; an air source access device sized and configured to provide communication with an insufflated operating cavity, an air conditioning set sized and configured to couple to the air source access device and the sheath, the air conditioning set including a powered air moving fan; and an air conditioning driver configured to be selectively attached and detached from the air conditioning set during normal use, the air conditioning driver including a source of power and a drive motor therein to drive the powered air moving fan so as to convey air from the insufflated operating cavity through the air source access device, through the air conditioning set, and through the sheath for passage across a lens of the laparoscope, to thereby maintain visualization of the insufflated operating cavity independent of operation of the insufflator circuit.
