  • STEERABLE AND FLEXIBLE ROBOTIC ENDOSCOPIC TOOLS FOR MINIMALLY INVASIVE PROCEDURES
    Publication number: 20250255466
    Abstract: A probe part includes a base member defining a first bore. A first elongated elastic member includes a near end secured to the base member and extends therefrom to a far end and defines a channel in communication with the first bore and that runs lengthwise with the first elongated elastic member. A first tendon has a first end and an opposite second end that is secured to the first elongated elastic member adjacent to the far end. The first tendon runs through the channel adjacent the first side and exits through the first bore exiting outwardly therefrom. Applying tension to the first tendon causes the first elongated elastic member to bend in the direction of the first side.

  • Steerable and flexible robotic endoscopic tools for minimally invasive procedures
    Patent number: 12318067
    Abstract: A probe part (100) includes abase member (110) defining a first bore (112). A first elongated elastic member (120) includes a near end (126) secured to the base member (110) and extends therefrom to a far end (128) and defines a channel (125) in communication with the first bore (112) and that runs lengthwise with the first elongated elastic member (120). A first tendon (130) has a first end and an opposite second end that is secured to the first elongated elastic member (120) adjacent to the far end (128). The first tendon (130) runs through the channel (125) adjacent the first side (122) and exits through the first bore (112) exiting outwardly therefrom. Applying tension to the first tendon (130) causes the first elongated elastic member (120) to bend in the direction of the first side (122).

A first tendon (130) has a first end and an opposite second end that is secured to the first elongated elastic member (120) adjacent to the far end (128). The first tendon (130) mns through the channel (125) adjacent the first side (122) and exits through the first bore (112) exiting outwardly therefrom. Applying tension to the first tendon (130) causes the first elongated elastic member (120) to bend in the direction of the first side (122).
