Abstract: The embodiments of the disclosure provide a method, apparatus, device and storage medium for presenting information, which relate to the technical field of computers. The method includes: obtaining object search information, in response to the object search information being object category information, determining a target object category corresponding to the object search information, and presenting object information of a plurality of target objects corresponding to the target object category in a search result presentation page; where all the plurality of target objects are different, and object information of a target object includes object attribute information and image resource information of the target object. By employing the above technical solution, when the user is searching the object category, object information of a plurality of target objects different from each other corresponding to the target object category is presented in the search result page.

Abstract: Devices, systems, and methods for hardware-based time synchronization for heterogenous sensors are described. An example method includes generating a plurality of input trigger pulses having a nominal pulse-per-second (PPS) rate, generating, based on timing information derived from the plurality of input trigger pulses, a plurality of output trigger pulses, and transmitting the plurality of output trigger pulses to a sensor of a plurality of sensors, wherein a frequency of the plurality of output trigger pulses corresponds to a target operating frequency of the sensor, wherein, in a case that a navigation system coupled to the synchronization unit is functioning correctly, the plurality of input trigger pulses is generated based on a nominal PPS signal from the navigation unit, and wherein, in a case that the navigation system is not functioning correctly, the plurality of input trigger pulses is generated based on a simulated clock source of the synchronization unit.

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.
