  • Patent number: 11399846
    Abstract: A ratchet assembly for use with an apparatus for applying surgical clips to body tissue includes a pawl and a biasing element. The pawl is slidably supported within a handle portion of the apparatus. The biasing element is supported by the handle portion and is in mechanical communication with the pawl. The biasing element has a biasing force configured to bias the pawl towards the rack such that the rack is permitted to translate in a distal direction, but is selectively inhibited from translating in a proximal direction until the rack is in a distal-most position. When the rack is urged in a proximal direction, the pawl exerts a force on the biasing element. When the force exerted on the biasing element is greater than the biasing force, the biasing element deflects allowing the pawl to disengage from the rack and permit the rack to translate in a proximal direction.

  • Patent number: 10905435
    Abstract: An endoscope treatment tool includes: a sheath; a clip unit; a biasing member arranged between a distal end part of the sheath and the clip unit; and a first rotation preventing part capable of preventing the clip unit from rotating relative to the distal end part of the sheath about a longitudinal axis. The clip unit includes: a clip body; a holding tube; and a second rotation preventing part capable of preventing the clip body from rotating relative to the holding tubes about the longitudinal axis. The biasing member biases the holding tube so as to separate from the distal end part of the sheath. When a proximal end part of the holding tube comes into contact with the distal end part of the sheath against the biasing force of the biasing member, the first rotation preventing part prevents the relative rotation of the clip unit.
