  • Patent number: 10702352
    Abstract: An operating portion which allows a bending treatment instrument to be inserted into an endoscope channel and bendably operated smoothly through intuition. The operating portion is connected with a device wire and bending wires and used to operate the treatment instrument and bend a freely bendable, bending treatment instrument, where the device wire is connected to a treatment instrument provided at a distal end of the bending treatment instrument and is used to operate the treatment instrument and the plurality of bending wires is used to bend the bending treatment instrument, the operating portion including: an operating portion body; a guide unit penetrated by the device wire; a bending wire pulling unit connected with the bending wires and swingably assembled onto the guide unit; and a grip portion connected with the device wire and configured to be reciprocable in an axial direction of the bending wire pulling unit.

  • Publication number: 20180078247
    Abstract: A hinge member of a bending treatment instrument in an endoscope channel and used bendably and capable of withstanding loads from grasping and resection motions of treatment instruments and a bending treatment instrument that uses the hinge member. Tubular hinge members arranged in a row substantially coaxially with one another make up the instrument and a hinge member includes: two recesses on edges of an end face on a proximal side in an axial direction; and two projections on an edge of an end face on a distal side shifted 90 degrees in a circumferential direction from the recess and facing each other in radial direction, wherein a bending-wire passage hole penetrating the hinge member in the axial direction is at a position avoiding the projections on the end face on the distal side, and a device-wire passage hole penetrating an axial center portion.

  • Publication number: 20160353979
    Abstract: Provided is a bendable treatment instrument that enables an individual doctor who is performing an endoscopic procedure to reliably and intuitively manipulate forceps, a knife, or the like. A bendable treatment instrument (1) includes a mechanism connecting, via a flexible tube body (4) encasing a transmission member, a bending section (3) configured to perform a bending action and a manipulation member (8) configured to receive a manipulation with respect to the bending section (3) from an operator. The mechanism is capable of transmitting a manipulation by the manipulation member (8) to the bending section (3). The bendable treatment instrument further includes a support member (7) configured to support the manipulation member (8) while clasping the flexible tube body (4), and a rotation support member (11) configured to support the manipulation member (8) so as to allow the manipulation member (8) to axially rotate with respect to the flexible tube body (4) at the support member (7).

  • Patent number: 8858397
    Abstract: A training machine for enabling the exerciser to exercise under a load appropriate for the individual exercise capability and physical function of the exerciser. The exerciser (E) enters a desired velocity-load characteristic into a load characteristic input device (7), and the velocity-load characteristic is stored in the load characteristic memory device (8). A load instruction value is determined according to the velocity-load characteristic and to the velocity inputted from a velocity calculation means (6) into the load characteristic memory device (8) and transmitted to a control means (1). The control means (1) rotates a servomotor (2) with a torque instruction value corresponding to the load instruction value. A movement mechanism (3) converts the rotation into linear movement to move a movable unit (4). With this, the exerciser can carry out training of reciprocal movement.

  • Patent number: 8337364
    Abstract: A training support system (S) allows an exerciser to practice training exercises safely and effectively with high motivation. The training support system (S) comprises a display means (4) which conducts display relating to training for the exerciser who uses a training machine (1) for muscle training, and a controller (3). The controller (3) allows dynamic display of reference motion and training motion on the display means (4) and variation of the display on the display means (4) according to the difference between the reference motion and the training motion.
