20090018550 | FRAGMENTATION AND EXTRACTION BASKET - A surgical instrument for fragmenting and extracting stones includes an outer sheath having a proximal end and a distal end and an inner core longitudinally extending through the core and longitudinally movable relative to the core. The outer sheath has a basket sized for entrapping the stones and located near the distal end of the outer sheath. The distal end of the inner core is longitudinally moveable from a retracted position within the basket to an extended position past the distal end of the outer sheath. The distal end of the inner core is also adapted to engage and fragment the stones. Longitudinal movement of the inner core relative to the outer sheath transforms the basket from an expanded condition to a collapsed condition to entrap stones within the basket and provide a small profile for insertion and withdrawal. | 01-15-2009 |
20100168520 | VIEW OPTIMIZER AND STABILIZER FOR USE WITH SURGICAL SCOPES - The present application discloses several 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 some embodiments, the view optimizer is provided in multiple parts enabling separation of one or more operator control features from engagement with the surgical scope. In some embodiments, the view optimizer features stabilization means for securement and positioning with the surgical scope. | 07-01-2010 |
20100198014 | Systems and methods for optimizing and maintaining visualization of a surgical field during the use of surgical scopes - 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. | 08-05-2010 |
20120022331 | Systems and Methods for Optimizing and Maintaining Visualization of a Surgical Field During the Use of Surgical Scopes - 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 C02 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. | 01-26-2012 |
20120165610 | SYSTEMS AND METHODS FOR OPTIMIZING AND MAINTAINING VISUALIZATION OF A SURGICAL FIELD DURING THE USE OF SURGICAL SCOPES - 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. | 06-28-2012 |
20120184897 | INTEGRATED SYSTEMS AND METHODS FOR MAINTENANCE AND MANAGEMENT OF AN INTRA-ABDOMINAL GAS ENVIRONMENT DURING LAPAROSCOPIC SURGERY - Air management control systems and methods maintain and manage an intra-abdominal gas environment during laparoscopic surgery. The systems and methods locate a plurality of in vivo sensors to monitor different environmental conditions within the operative space insufflated with pressurized CO2, e.g., CO2 insufflation airflow velocity, CO2 pressure, aspiration airflow velocity, and at least one of humidity level, temperature, density of smoke/particulates, odors, and sound within the operative space. The systems and methods couple the plurality of in vivo sensors to a master controller. The master controller implements pre-programmed rules to generate control commands that govern the delivery of pressurized CO2 and aspiration pressure into and out of the operative space in response, at least in part, to the different environmental conditions monitored by the in vivo sensors. | 07-19-2012 |
20120197084 | SYSTEMS AND METHODS FOR OPTIMIZING AND MAINTAINING VISUALIZATION OF A SURGICAL FIELD DURING THE USE OF SURGICAL SCOPES - 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 CO | 08-02-2012 |
20120310147 | DEVICES, SYSTEMS, AND METHODS FOR PERFORMING ENDOSCOPIC SURGICAL PROCEDURES - Methods and systems for accessing an operating cavity when performing endoscopic surgery comprising. The systems and methods include at least one obturator-free cannula unit and a trocar assembly. The trocar assembly includes a single dedicated functional obturator independent of the cannula unit and an endoscopic cannula. The invention also provides a system and methods for providing continuous flow of carbon dioxide during a laparoscopic procedure. | 12-06-2012 |
20140371763 | SHEATH FOR HAND-HELD AND ROBOTIC LAPAROSCOPES - A sheath for providing a dynamic air shield relative to a distal portion of a laparoscope disposed within the sheath includes a sheath elongate body having an inner surface and an outer surface, a plurality of lumens, and a distal portion configured to deflect air from the lumens across the surface of a laparoscope. The sheath can include a registration and alignment feature configured to align the sheath with a laparoscope. Further, the sheath can be configured to work with robotic laparoscope systems. | 12-18-2014 |
