Abstract: A insertable gripping instrument and a gripper thereof. The gripper comprises at least two gripping arms. Each gripping arm comprises a gripping head and a bendable portion. The gripping arms are used to grip a target object. Each bendable portion is provided with a deformation structure capable of bending towards the closing direction of the gripper and/or bending towards the opening direction of the gripper. In the present structure, the sleeve in existing structures is omitted, and in combination with the deformation state of the bendable portion, the gripper open and close on the basis of the position change of moving members.

Abstract: A manufacturing method for an integrated gripper, and a integrated gripper manufactured by using the manufacturing method. In the method, a laser is used on a cylindrical substrate, and the integrated gripper provided with at least two gripping arms is cut out, each gripping arm being provided with a gripping head and first shrinkage slit distributed along the axial direction of the substrate. By means of the first shrinkage, bendable portions are provided with a deformation structure capable of bending in a closing direction of the gripper and/or an opening direction of the gripper.

Abstract: A visual ureteroscope includes a ureteroscope body and a ureteroscope tip. The ureteroscope tip includes a tip portion and an image capture device, wherein the tip portion is arranged at a front end of a ureteroscope tube of the ureteroscope body; the tip portion has a camera end face and an aspiration end face; the tip portion includes an aspiration hole, which is in communication with an aspiration channel of the ureteroscope body, and an operating hole for an operating component to pass therethrough, the aspiration hole axially extending forwards from the aspiration channel to the aspiration end face to form an aspiration opening, and the operating hole obliquely extending forwards such that the operating component that passes out from the operating hole, obliquely extends forwards to extend out of the tip portion; and the image capture device comprises a camera.

Abstract: Disclosed is an impact-during-suction surgical ureteroscope, comprising: a ureteroscope main body, an operating portion operably arranged in the ureteroscope main body, and a lithotripter. The ureteroscope main body comprises a ureteroscope structure main body and a suction channel extending from a front end to a rear end in the ureteroscope structure main body. The suction channel has a suction opening at the front end. The lithotripter is movably disposed in the ureteroscope structure main body so as to switch between a first state and a second state. When in the first state, a cutting head of the lithotripter extends out of the suction opening so as to impact a stone; when in the second state, the cutting head of the lithotripter is retracted into the suction opening and is used to impact crushed stones blocking the suction opening.
