  • Publication number: 20190150969
    Abstract: A treatment tool comprises a housing and a rotary element configured to be attached to the housing so as to define the treatment tool for treating an examinee. The rotary element is defined by an elongated member being rotatable about a rotational axis with respect to the housing. A rotary member is attached to the elongated member to rotate the elongated member. The rotary member is disposed coaxially with the elongated member and rotatable with respect to the housing. A locking member is used for unlocking the elongated member from the housing for rotation in response to rotation of the rotary member to allow the elongated member to rotate in the same direction as the rotary member in response to rotation of the rotary member and locking the elongated member against rotation with respect to the housing upon stopping of relative rotation between the rotary member and the housing.

  • Publication number: 20190117246
    Abstract: In a treatment instrument, one of a pair of jaws is supported by a supporter while being pivot able around the supporter with respect to the supporter. A drive member moves along a longitudinal axis so that the pair of the jaws are closed with respect to each other, thereby applying an axial force onto an elongated member from the drive member by way of the one of the jaws and the supporter in a direction along the longitudinal axis. A contact surface of the elongated member abuts on a housing when the elongated member moves with respect to the housing under the axial force, thereby suppressing rotation of the elongated member around the longitudinal axis with respect to the housing.

  • Patent number: 10048093
    Abstract: A magnetism detecting element detects a leakage magnetism from a scale, on which a magnetic signal with a constant period is recorded, and a relative position between the scale and the magnetism detecting element is detected. The magnetism detecting elements are arranged, along a detection direction of the magnetic signal relative to the scale, in a pattern with a pitch of ½n (n is a prime number of 3 or more) of a wavelength ?? of a signal output by the element. Furthermore, as the pattern for cancelling m odd-order harmonics, the m-th power of 2 magnetism detecting elements are arranged within a range in which a pitch distance L of the magnetism detecting element farthest in the detection direction is expressed by L=(??/2)×(?+?+ 1/7+ . . . 1/(2m+1)).

  • Patent number: 9949781
    Abstract: A grasping treatment unit includes a first jaw, and a second jaw openable and closable relative to the first jaw. In the first jaw, a heating wire continues without branching from a first extending end to a second extending end, and heat is generated over an entire length from the first extending end to the second extending end when the electric current flows through the heating wire. In a heating portion, a calorific value per unit area is higher in a distal portion than in a proximal portion in the first jaw when the heat is generated from the heating wire. On a treatment surface of the first jaw, an amount of heat transfer from the heating portion is greater in the distal portion than in the proximal portion.
