International Classification:

A61B 18/14

US Classification:

606 51

Abstract:

A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy though tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.

International Classification:

A61B 1/06

US Classification:

600169

Abstract:

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.

International Classification:

A61B 1/12

US Classification:

600123

Abstract:

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.

Assignee:

MINIMALLY INVASIVE DEVICES, LLC - Columbus OH

International Classification:

A61B 1/00

US Classification:

600121, 600158

Abstract:

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.

Assignee:

MINIMALLY INVASIVE DEVICES, LLC - Columbus OH

International Classification:

A61B 1/12

US Classification:

600157

Abstract:

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.
