  • Patent number: 10729307
    Abstract: The present disclosure relates to an image processing device, an image processing method, and a surgical system that enable detection of a region including a specific living body site in an intraoperative image on the basis of a frequency of a motion vector of a living body in the intraoperative image. A motion detection unit detects the motion vector of the living body in the intraoperative image using the intraoperative images at different times. The analysis unit obtains the frequency of the motion vector detected by the motion detection unit. A frequency map generation unit detects the region including the specific living body site in the intraoperative image on the basis of the frequency obtained by the analysis unit. The present disclosure is applicable to, for example, a CCU and the like of an endoscopic surgical system.

    Abstract: A method is described for treating glaucoma by surgically implanting a shape recoverable member in the sclera of the eye. The shape recovery member is adapted to recover involutely when shape recovery is caused to occur. The bending of the shape recoverable member during its recovery exerts pressure on longitudinal ciliary muscle to supply tension to and open the trabecular meshwork. As a result, aqueous humor flows more freely and reduces the intraocular pressure.

  • Patent number: 9504467
    Abstract: In some embodiments, a method includes extending a dilator into a body of a patient in a first direction such that a distal end portion of the dilator extends from the body. The dilator defines a lumen therethrough. At least a portion of the dilator is disposed within the body when the distal end portion extends from the body. At least a portion of an implant is passed through the lumen defined by the dilator. The dilator is removed from the body by moving the dilator in the first direction.

  • Patent number: 9492187
    Abstract: A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow needle. The coaxial surgical instrument includes end effectors at the end of the shaft which are biased to an open position such that when the end effectors of the surgical instrument extended out of the needle they open, and they are closed by relative movement of the needle over them. The assembly preferably includes a first fixing element which is used to fix the relative location of the surgical instrument and the needle. The assembly also preferably includes a second fixing element which moves relative to the needle and is located on the outside thereof and which is used to fix the relative location of the needle to the patient.

  • Patent number: 9452273
    Abstract: For cricothyrotomy and the like, a surgical device has, in one embodiment, a device body with a bi-directional scalpel, an end cap, and a tracheal hook that fits within a channel formed in the device body. With the end cap removed to expose the bi-directional scalpel blade and with the tracheal hook fully inserted within the body channel, the device can be held, e.g., in the dominant hand of an operator, and manipulated to make an opening in the patient's neck using the exposed scalpel blade. The tracheal hook can then be slid away from the device body with the hook's barbed tip entering the opening to enable the operator to easily and quickly secure the surgical airway. The design of the surgical device enables an economy of movements that otherwise would typically not be within the skill set of an operator who was not a surgeon.

  • Patent number: 9402536
    Abstract: A surgical assembly includes a cannula and an obturator. The cannula has open proximal and distal ends defining a lumen therebetween. The lumen defines an inner surface of the cannula having a mating structure. The obturator is generally tubular and has an outer surface including a corresponding mating structure. The respective mating structures of the obturator and the cannula engage each other so as prevent relative rotation of the obturator and cannula, and to prevent inadvertent disconnection of an upper valve housing attached to the cannula.
