A view optimizing assembly, method and kit for use in combination with a laparoscope having a lens located on the shaft tip of the laparoscope, and a source of insufflation CO2. The invention includes a multi-lumen sheath assembly, a deflector assembly in fluid communication with the lumens of the sheath assembly, wherein the flow of CO2 through the lumens forms a vortex when coming into contact with the deflector assembly, thereby preventing fogging of the laparoscope lens.

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.

Systems and methods make use of a view optimizing assembly having a deflector assembly with critical physical, pneumatic, and optical characteristics that make possible intra-operative defogging, surgical debris deflection, and cleaning of a laparoscope lens during minimally invasive surgery, while also maintaining visualization of the surgical site. The view optimizing assembly can incorporate a quick exchange feature, which makes possible a surgical method for maintaining clear visualization that includes the ability to make a quick exchange of laparoscopes having different operating characteristics (e.g., laparoscopes with different tip angles, lengths, or diameters) entirely on the sterile operating field and without interference with the preexisting surgical set-up on the sterile operating field. The view optimizing assembly integrates with the existing suite of minimally invasive instrumentation. It does not interfere with the surgical set-up, and it requires minimal change in the process or practice of a surgical operating room (OR) team.

The present application discloses several embodiments of a devices for maintaining visualization with a surgical scope. The embodiments of the device are adapted to shield, defog or clean the lens of the surgical scope while the surgical scope is being used to perform a surgical procedure within a patient's body. In one embodiment, a view optimizer is provided that is adapted to deliver at least one fluid to the objective lens of the laparoscope to clean and / or defog the objective lens of the laparoscope without the need to remove the laparoscope from the surgical field. In additional embodiments, a view optimizer is provided that is adapted to create leakage or venting of gas from the body cavity so as to ensure continuous gas flow from an insufflator.

Systems and methods couple a self-contained air processing or conveying component to a sheath that is sized and configured to receive a laparoscope including a laparoscopic lens providing visualization of an operating cavity. The air processing or conveying component comprises an air flow path having an inlet sized and configured for communication with a source of CO2 and an outlet. The air processing or conveying component includes a driven air moving component in communication with the air flow path sized and configured to continuously convey CO2 from the source through the air flow path to the outlet. The sheath coupled to the air processing or conveying component can include a lumen communicating with the outlet of the air processing or conveying mechanism for passing CO2 continuously conveyed by the driven air moving component across the laparoscopic lens to maintain visualization of the operating cavity. The sheath and self-contained air processing or conveying component can comprise an integrated assembly. The source of CO2 can comprise a laparoscopic access device for accessing the operating cavity insufflated with CO2 by operation of an insufflator circuit. The driven air moving component continuously conveys CO2 from the operating cavity across the laparoscopic lens to maintain visualization of the operating cavity, independent of operation of the insufflations circuit.

A method of dental microscopic procedure, using a digital surgical scope, includes steps for selecting a function of the digital surgical scope to perform, obtaining the corresponding images from the image data taking device or the image data processing / storing device, processing the images by the image data processing / storing device, and displaying the images on the displays. The dental surgical procedure is done by seeing the images displayed on the screen. The digital surgical scope includes a microscope lens assembly for magnifying an optical image of an object and an in-line illumination device for illuminating the object along the same optical axis and from the same direction of the microscope lens assembly. The image data processing / storing device is for manipulating the image taken by the microscope lens assembly and the image data taking device.

A device and method for cleaning or defogging a surgical scope during minimally invasive surgery, including a casing which houses a sponge and a heating element configured to be accessible to the surgical scope and the casing is configured to removably attach to a trocar during a surgical procedure.

A laparascope and endoscope cleaning and defogging device with a port located horizontally that is used to warm the scope prior to insertion into the body cavity / surgical site. The scope punctures the initial membrane and enters the cavity between two bodies of absorbent material that contain fluid. The absorbent material is arranged such that the passage of a scope would be accommodated for different sizes of surgical scopes. A circuit board is located on the bottom of the chamber that has a design element used to warm the liquid to a temperature equal to or greater than the temperature of the proposed surgical environment. When the scope is located between the two absorbent bodies, the heat generated by the circuit board is transferred via the liquid and contacts the scope, warming it in preparation for surgery.

A surgical scope employing a multi-spectrum ring illuminated surgical camera with a ring lens and a plurality of sources of light set behind the camera and positioned radially about the longitudinal axis of the lens and / or scope.
