  • Patent number: 11337586
    Abstract: Disclosed herein is an aspiration assembly for attaching to an endoscope. The aspiration assembly comprises an extendable suction tube for aspirating an object (e.g., smoke, blood, blood clot, bone debris, or tissue debris) at or near a surgical site during an endoscopic surgery. The aspiration assembly can further comprise an irrigation tube for directing a fluid to the surgical site for cleaning the endoscope lens. By integrating an extendable suction tube with the endoscope, the technology described herein obviate the need for instrument switching and/or multiple surgeons during the surgery.

    Abstract: A user friendly, safe and efficient continuous flow irrigation endoscope having only a single housing sheath without an inner sheath. The exclusion of the inner sheath increases the effective lumen of the endoscope. A long hollow cylindrical tube, capable of performing a to and fro and rotary motion, is placed inside the housing sheath to function as an endoscopic instrument, but also to serve as a conduit for evacuating waste fluid and detached tissue pieces present inside a tissue cavity. A single inflow port located at the proximal end of the single housing sheath allows the irrigation fluid to enter the tissue cavity via the lumen of the said housing sheath. The invented endoscope system has a single inflow port, a single outflow port, without an inner sheath so that all waste fluid and tissue debris present inside cavity are evacuated via the same single outflow port.

  • Publication number: 20150038790
    Abstract: Chronic sinusitis is treated by the application of cold plasma or plasma-activated species to the infected mucosal surfaces through use of an endoscope having a steerable end which may be projected into the sinus cavities through the nasal cavity. The cold plasma is generated at either the distal end of the endoscope with a power source by application of a power, or at the distal end by gas and electrical connections extending through the endoscope. The cold plasma or plasma-activated species act to destroy bacterial cells but not eukaryotic cells.

  • Patent number: 8920456
    Abstract: A vessel harvesting apparatus is provided for removing a vessel from a patient. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. The endoscopic instrument has an insufflation channel adapted to receive an insufflation gas from a regulated source at the proximal end. The insufflation channel has an outlet at the distal end adapted to expel the insufflation gas subcutaneously in the patient. A damping device has a flexible bladder with an inside space in fluid communication with the insufflation channel. The inside space has a volume that varies between a rest volume and an inflated volume in response to an amount of insufflation gas flowing to or from the flexible bladder.

  • Patent number: 8915842
    Abstract: Methods and devices are provided for providing irrigation and/or suction to a surgical site and maintaining clear visibility through a lens of a scoping device during a surgical procedure. In general, the methods and devices can allow for a surgical instrument to maintain visibility during a surgical procedure using a fluid conduit coupled to the surgical instrument. A surgical device can include a sheath having at least one lumen extending therethrough configured to allow a surgical viewing instrument to be disposed therein. The sheath can also have a passageway extending therethrough configured to allow fluid to flow therethrough. The fluid conduit can be configured to be movable between positions that can allow alternative directions of fluid toward and/or away from a viewing element on the surgical instrument and fluid away from the viewing element and toward a surgical field in a body cavity.

  • Patent number: 8911363
    Abstract: A continuous flow irrigation endoscope and a continuous flow irrigation fluid management system, both designed to be compatible to each other and meant to function as a single system. The endoscope and the fluid management system are synergistic to each other such that both enhance the efficiency of each other. The system allows a body tissue cavity to be distended by continuous flow irrigation so that the detached tissue pieces and waste fluid present inside a body tissue cavity are continuously automatically evacuated from the tissue cavity without causing the cavity to collapse at any stage and without the need of withdrawing the endoscope or a part of the endoscope from the tissue cavity.

  • Publication number: 20140343358
    Abstract: Described herein are various detachable secondary imaging endoscopic devices that can be used in conjunction with an endoscope to provide additional fields of view so that multiple regions of a body cavity may be imaged simultaneously. In one variation, a secondary imaging endoscopic device comprises an endoscope attachment member configured to be disposed over an endoscope, a first imaging element and a corresponding first light source at a first location on the endoscope attachment member, and a second imaging element and a second light source at a second location that is adjacent to the first location. In some variations, a secondary imaging device comprises a fluid delivery module having one or more ports for fluid delivery. The multiple simultaneous images acquired by the secondary imaging endoscopic device imaging elements and the main endoscope imaging element can be combined or arranged together to form a continuous view of a body cavity.

  • Patent number: 8888689
    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.

  • Patent number: 8888683
    Abstract: A scope adapted for insertion and manipulation in a difficult pathway is disclosed. The scope comprises at least one module for manipulating the scope. The scope may further comprise an illumination source, an image sensor, a power source, and a viewing member for viewing images of a cavity or other anatomical member of a patient. In one embodiment the scope is intended to facilitate insertion of an intubating device, which comprises an elongated semi-rigid stylet including first and second ends and at least one inner lumen connected to a module. Additionally, a flexible tip is provided for manipulating one end of the scope and allowing greater flexibility when maneuvering a difficult pathway. In another embodiment, fluids are provided through an interior portion of the scope, allowed to at least partially contact the lens located at the distal end of the scope, and subsequently cleanse or defog the lens for improving vision via the scope.
