  • Patent number: 10285580
    Abstract: A video endoscope comprises a shaft comprising a rigid, proximal-side section and a distal section that is laterally deflectable in a plane from the central longitudinal axis of the shaft. A housing is arranged at the proximal end of the shaft. A control element for controlling the deflection of the shaft is provided at the housing. A rod-like pull element extends in the shaft in an off-center fashion with respect to the central longitudinal axis. The pull element is coupled with the control element and with a distal end of the deflectable section of the shaft, wherein a movement of the pull element by the control element in the proximal direction effects a lateral deflection of the deflectable section. A push tube is provided that is arranged to encase the exterior side of the pull element. The push tube extends from the proximal connection of the pull element with the control element through the first opening into the shaft.

  • Patent number: 10149607
    Abstract: A highly articulated robotic probe (HARP) is comprised of a first mechanism and a second mechanism, one or both of which can be steered in desired directions. Each mechanism can alternate between being rigid and limp. In limp mode the mechanism is highly flexible. When one mechanism is limp, the other is rigid. The limp mechanism is then pushed or pulled along the rigid mechanism. The limp mechanism is made rigid, thereby assuming the shape of the rigid mechanism. The rigid mechanism is made limp and the process repeats. These innovations allow the device to drive anywhere in three dimensions. The device can “remember” its previous configurations, and can go anywhere in a body or other structure (e.g. jet engine). When used in medical applications, once the device arrives at a desired location, the inner core mechanism can be removed and another functional device such as a scalpel, clamp or other tool slid through the rigid sleeve to perform.

Therefore, a work load in disassembling and assembling of a distal end portion can be set appropriately, and workability in disassembling and assembling is improved.

  • Patent number: 10031217
    Abstract: A method for operating an ultrasonic sensor with a housing and at least an ultrasonic converter comprising a surface for emitting and receiving ultrasonic waves, whereby ultrasonic waves are emitted towards an object at different points in time, whereby the ultrasonic waves being reflected from the object are received by the surface and whereby a signal 1, 2 is generated by the received ultrasonic waves is characterized in that the relative position of the surface with respect to the object is modified in such a way that the relative position is different at consecutive points in time and that the signals 1, 2 of two consecutive points in time are subtracted from each other. Further an ultrasonic sensor for carrying out the method is described.

  • Patent number: 9955986
    Abstract: A basket apparatus is described that assists in removing objects from within a patient. The apparatus includes a number of pull wires, each pull wire physically coupled to a different capstan that individually actuates one of the pull wires. The apparatus also includes an outer support shaft itself including a number of channels through which the pull wires traverse. The portions of the pull wires extending out of the outer support shaft form a basket of adjustable size, shape, and position. The pull wires are attached together at a tip located at a distal end of the basket apparatus. By controlling the actuation of the various pull wires, the basket's shape, position size can be manipulated to reposition the basket around an object located within a patient, independent of or in conjunction with motion of the remainder of the apparatus or an associated endoscope.

  • Patent number: 9925367
    Abstract: A method of laparoscopically implanting an electrically stimulating lead proximate the lower esophageal sphincter (LES) of a patient includes delivering the lead through a port of a laparoscope inserted into the abdominal cavity of the patient through an incision in the abdominal wall. The stimulating electrode is implanted in or proximate the muscularis layer of the lower esophageal wall to treat esophageal reflux disease (GERD). The lead includes a needle and suture at its distal end for pulling the electrode into the muscular wall of the LES. Clips are applied to the suture attached to the distal end of the lead to prevent retrograde movement of the electrode. The lead also includes an anchoring member for anchoring the portion of the lead proximal to the electrode. The method and lead used with the method allow the surgeon to work within the confined anatomy present at the gastroesophageal junction and prevents backwards movement and dislodgment of the electrode.
