Smart controller protective cover
This utility model discloses a protective cover for an intelligent controller, including an intelligent controller body. The surface of the intelligent controller body is provided with a button control area, a display area, and a protective cover covering the upper surface of the button control area. One end of the protective cover is a hinged end, and the upper and lower ends of the hinged end are respectively provided with a first connecting post and a second connecting post. The intelligent controller body is respectively provided with a first slot and a second slot that cooperate with the first connecting post. The depth of the first slot is greater than that of the second slot. When the protective cover moves upward, the second connecting post can be pulled out of the second slot; when the protective cover moves downward, the first connecting post cannot be pulled out of the first slot. This application ensures the safety of the protective cover during use through a unique slot design. The difference in depth between the first and second slots effectively prevents the protective cover from being accidentally removed and falling off in case of accidents, improving product reliability and user experience.

A basket stone extraction device with biliary tract flushing function
ActiveCN224387498Usee clearlyImprove stone extraction efficiencyDiagnosticsSurgeryHuman bodyBiliary tract
The utility model provides a kind of net basket stone extraction device with biliary tract flushing function, including catheter, fixed ring, guide wire, flush pipe, pipeline guide silk;Wherein, catheter is equipped with first lead-through cavity, and multiple second lead-through cavities;First through-hole is set in fixed ring middle part;Guide wire is worn in second lead-through cavity, and front end forms net basket;Flush pipe is installed in first lead-through cavity, with infusion cavity;Pipeline guide silk is worn in the infusion cavity of flush pipe. When using, the front end of catheter is sent to calculus place through endoscope;Physiological saline is injected in flush pipe, and calculus periphery adherend is washed;Then flush pipe is extracted, then guide wire is pushed to make net basket open and cover calculus, and is withdrawn with endoscope;After calculus is extracted, flush pipe is installed by pipeline guide silk, and is entered again to flush biliary tract and remove residue. The device reduces operation time and complexity, avoids multiple instruments cross into human body, and reduces biliary tract injury and bleeding risk.

Method and apparatus for spatial path visualization coupling toponym labels with voronoi diagrams
ActiveCN120744013BIntuitive semantic expression effectEffectively express the overall trendNavigational calculation instrumentsVisual data miningComputer graphics (images)Algorithm
The application provides a spatial path visualization method and device coupling a place name label and a Voronoi diagram, relates to the technical field of geographic information visualization, and comprises the following steps: preprocessing obtained initial path data to generate a path point sequence; obtaining a point of interest score corresponding to a specific type parameter of each city in the path point sequence, determining a first display space corresponding to each city based on the sum of the point of interest scores, and determining a second display space corresponding to each type of the specific type parameter in the first display space based on the point of interest scores of different types of the specific type parameter in each city; and performing word cloud rendering on the second display space to generate a visual path parameter display diagram. The application divides spatial regions hierarchically through a weighted Voronoi diagram, fills the corresponding POI word cloud information in each subregion, and makes the path visualization have higher information bearing capacity and more intuitive semantic expression effect.
