  • Publication number: 20130053638
    Abstract: The endoscopic nasal palatoplasty procedure provides a reduction in the posterior aspect of the soft palate and/or uvula, thereby increasing the area of the nasopharyngeal passage between the soft palate and/or uvula and the back of the nasopharynx. This increased nasopharyngeal area promotes nasal breathing, thereby reducing reliance upon oral breathing and corresponding sleep-disordered breathing syndrome and associated problems such as sleep apnea and snoring. The procedure is performed using a conventional surgical implement, such as a Coblator® or other electro cauterizing or laser cauterizing implement, to ablate and cauterize a series of lesions in the soft palate and/or uvula. The procedure is performed by inserting the surgical implement through one of the nasal passages to access the superior surface of the soft palate and/or uvula.

The linear-members are inserted in the tubular-member, one end and the other end of each of the linear-members being fixed to the vicinity of a joint of the tubular-member and the drive-unit, respectively. The drive-unit moves the linear-members. The position-detector and the tension-detector detect positions and tension of the linear-members, respectively. A desired position/posture of a point of interest is input to the operation-unit. The calculation-unit calculates a current position/posture of the point, a weighting factor serving to give priority to and move the linear-members the tension of which is relatively low among the linear-members, and movement degrees of the linear-members to move the point to the desired position/posture, and causes the drive-unit to pull the linear-members.

A portion penetrating a supporting member 21 of a treatment portion 5 is a first pivot shaft 23. The first pivot shaft 23 is also a rotational axis of a pair of forceps members 22 provided in the treatment member 5. When the forceps members 22 are used, a coil sheath 6 is extended by an operation at the side of the proximal end. The connection member 4 rotates about the second pivot shaft 15, which is a fulcrum, and the treatment portion 5 moves forward beyond the cap 12. In accordance with the present invention, it is possible to resolve the difficulty of procedures by positioning the treatment portion in an appropriate location.

  • Patent number: 8221306
    Abstract: In an endoscope therapeutic device having a plurality of introduction guide tubes for introducing a treatment tool into a body cavity, the introduction guide tubes are mutually joined at a position more proximal than bending portions thereof. Accordingly, the effects caused by the movement of the plurality of the introduction guide tubes are mutually invalidated at a joint portion as a fulcrum, so that the position of the introduction guide tube is relatively stabilized in the body cavity. As joining methods, there are integration, usage of a joint tool, and usage of an over tube. The operability is improved when the introduction guide tube is provided at the distal end thereof with a mechanism for retaining and/or rotating a distal end of a treatment tool inserted therethrough.

    Abstract: A medical device designed for gastrointestinal endoscopists who require a more effective means of removing blood clots from the upper GI tract during episodes of upper GI bleeding. It is an endoscope attachment that breaks down blood clots, allowing them to be removed through the existing endoscope suction channel. Current methods are time-consuming, ineffective, and often life-threatening. This device offers an efficient alternative that makes the procedure quicker, safer, easier, and more cost-effective. The product offers simple solution to a life-threatening problem.
