  • Patent number: 11209661
    Abstract: This lens driving device comprises an autofocus (AF) driving unit and a shake correction driving unit, wherein a shake correction support member has a pair of power supply suspension wires and a pair of signal suspension wires. While an AF movable unit includes a position detecting magnet, an AF fixation unit includes an AF power source line, a signal line, a coil power source line, and an AF control unit. The AF control unit includes a hole element, and a coil control unit which controls current passing through an AF coil part, and an AF circuit board on which the hole element and the coil control unit are mounted. As a result of contact between a lens holder and a base which has rigidity higher than that of a coil substrate, movement of the AF movable unit toward a formed image in the optical axis is restricted.

  • Publication number: 20210267669
    Abstract: In a method for treating gastroesophageal reflux disease, an insertion portion of an endoscope is inserted from a cardia into a stomach. A distal end portion can be bent to position a cardiac region and a cautery unit in a field of view of an observation mechanism. The cautery unit can be brought into contact with a first region of a stomach wall around the cardia to cauterize the first region without removing a mucosal layer thereof while the cautery unit and a proximal portion of the insertion portion proximal of the bend are separated from each other by a predetermined distance or more. A position of the cautery unit with respect to the stomach wall can be changed while the separation state is maintained to bring the cautery unit into contact with and cauterize a second region of the stomach wall without removing a mucosal layer thereof.
