Having Auxiliary Channel Patents (Class 600/153)
  • Patent number: 10772652
    Abstract: A surgical system can include a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument can include a second channel. A valve coupled to the first instrument controls fluid flow through the first channel. The valve has at least two positions and in one position, the impedance of fluid flow through the valve into the first channel (when the second instrument is not received in the first channel) is substantially the same as when the valve is the other position and the first channel partially blocked by the second instrument. In another aspect, a surgical system can include an outer member and the first instrument can be received within the outer member to define a second channel there between. The first instrument can include a visualization system and an illumination system.

  • Patent number: 9839414
    Abstract: In the biopsy system according to one embodiment, the needle tube of the treatment tool has the minor axis of the flattened portion and the bending plane of the bending portion parallel to each other. Accordingly, the needle tube is easily bent in the bending direction of the bending portion, and even in an endoscope that has few bendable directions and is bendable, for example, in only two directions (e.g., up and down), the bending operation of the bending portion is not easily hindered. As a result, even after the treatment tool for endoscopes is inserted into the endoscope, the bending portion can be easily bent with a predetermined bending amount, and a procedure can be easily performed.

  • Patent number: 8864654
    Abstract: The foregoing application describes a system and method of performing a minimally invasive surgical operation. More specifically, the invention involves the use of disposable cannula and slender dilators of variable lengths, which incorporate a source of illumination to carry light to a surgical site and video capabilities for capturing and displaying images from a CMOS or CCD camera device. According to one embodiment, fiber optics run semi-circumferentially or along walls of the cannula/dilator and terminate at about a centimeter from the distal end of the cannula/dilator, thereby preventing illumination from “bottoming out” at the floor of the incision. According to one alternate embodiment, the light fibers may be fashioned in an annulus around one or more camera chips to provide illumination and video of the surgical site.

  • Patent number: 8852085
    Abstract: A surgical system includes a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument defines a second channel. A valve coupled to the first instrument controls fluid flow through the first channel, such that impedance of fluid flow through the first channel is substantially the same without the second instrument received in the first channel and with the first channel partially blocked by the second instrument. In another aspect, a surgical apparatus includes an outer member and an inner member received within the outer member to define a first channel therebetween. The inner member houses an optical lens and defines a second channel for receiving a surgical instrument. The first and second channels are configured such that a pump having an inflow rate of up to about 0.7 L/min connected to the second channel can maintain fluid pressure inside an organ.

  • Patent number: 8821389
    Abstract: An endoscopic aspiration device is mounted on a manipulating head of an endoscope, from which an elongated insertion rod member is extended forward, the endoscopic aspiration device being composed of a valve casing which is mounted on the manipulation head in communication with an aspiration passage running through the insertion rod member, and a valve assembly unit including a valve member, a valve guide member and a connector member attached to the valve guide member to communicate same with a proximal aspiration passage on the side of a suction source. The valve member is put in a sliding displacement along the valve guide member to bring the aspiration passage into and out of communication with the proximal aspiration passage on the side of a suction source. The valve guide member is coupled with the valve casing through a coupling mechanism which permits to turn the valve assembly unit on and relative to the manipulating head.

  • Patent number: 8734330
    Abstract: Described herein are various systems and methods for directing endoscopy instruments to varying positions at a target site. In one aspect, at least one instrument channel has multiple exit points at the distal end of the guide tube, and the position of an instrument delivered through the channel may be switched between the different exit points. In another aspect, an instrument channel splits into multiple branches at the distal end of the guide tube, and the position of an instrument at the target site may be changed by selectively directing the instrument into a different channel branch. In yet another aspect, the guide tube, or a portion thereof, may be rotated to reposition an instrument at the target site. The capability of changing the instrument positions during a procedure would enable a physician to examine or treat multiple target sites within an operative field, without necessitating the full retraction of the instruments or the guide tube from the operative field.

  • Patent number: 8727966
    Abstract: A medical device such as an endoscope, a laparoscope, or other device including an entry guide uses outriggers or arms that are mounted on the distal end of the entry guide and rotationally deployed to provide separation of instruments when the entry guide reaches a work site. Deployment can be implemented with as few as one cable or actuator to operate the arms. This mechanism may achieve working separation in a short axial length without complicating instrument channels that may be used for other instruments introduced through the entry guide.
