Auxiliary supporting guide wire for torsion of ureter
PendingCN122075894AAvoid "stick-slip" damageAvoid the risk of pressure surgesGuide wiresSurgeryKidney pelvisUretero-ureteral
The invention relates to the technical field of medical auxiliary instruments, in particular to a ureter distortion auxiliary supporting guide wire which comprises an extension guide wire, a position guide wire, a guide wire head and a connecting sleeve seat. The position guide wire is provided with an expansion base ring and at least three sets of plate type expansion assemblies driven by a pneumatic mechanism I. The plate type expansion assemblies drive arc-shaped expansion plates to swing through tooth bars, point type and controllable expansion of the narrow portion of the ureter is achieved, and the problems of mucous membrane damage and complete lumen blockage caused by large-area contact of a traditional air bag are solved. And meanwhile, an air cavity and at least three groups of radial movement positioning assemblies driven by a pneumatic mechanism II are arranged in the guide wire head, and an arc-shaped positioning plate is pushed by a multi-stage telescopic cylinder to extend out in the radial direction to form multi-point contact with the inner wall of the renal pelvis, so that stable anchoring of the guide wire head is realized. The operation injury risk can be effectively reduced, smooth perfusion is guaranteed, and the positioning stability of the guide wire in the renal pelvis is improved.

Writing health prompting method, handwriting pen and storage medium
The application discloses a writing health prompting method, a handwriting pen and a storage medium, and relates to the technical field of input device control. The method is applied to the handwriting pen, and the handwriting pen comprises a pressure detection module, a posture sensing module, a main control module and an addressable light source. The method is executed by the main control module, and comprises the following steps: acquiring pen tip pressure data of a pen tip of the handwriting pen acting on an input surface collected by the pressure detection module; acquiring spatial posture data of a pen body of the handwriting pen relative to a reference surface collected by the posture sensing module; generating a pressure feedback parameter based on a preset pressure interval and the pen tip pressure data; generating a posture feedback parameter according to a preset holding posture and the spatial posture data; and controlling the addressable light source to perform visual feedback based on the pressure feedback parameter and / or the posture feedback parameter.

Ultrasound and spraying combined rapid detection method for leakage of external window of building
ActiveCN121898688AAccurate detectionQuick checkDetection of fluid at leakage pointAnalysing solids using sonic/ultrasonic/infrasonic wavesWater leakageSpray nozzle
The invention relates to an ultrasonic and spraying combined rapid building external window leakage detection method, which comprises the following steps of S1, suspending an ultrasonic transmitting part on the outer side of a to-be-detected external window, and arranging an ultrasonic receiving part on the inner side of the to-be-detected external window; s2, the ultrasonic receiving part is moved to the detection position of the to-be-detected outer window and moves along the detection position, the ultrasonic receiving part is moved to collect ultrasonic signals of multiple positions and convert the ultrasonic signals into intensity values, the multiple intensity values are calculated to obtain an average value, and the average value is a reference value; s3, moving the ultrasonic receiving piece to each detection position of the to-be-detected outer window, and marking the corresponding position as a sound leakage part when the intensity value exceeds the reference value and reaches the initial judgment intensity difference value in the moving process; s4, spraying the correspondingly marked sound leakage part on the outer side of the outer window to be detected by a spray head on the unmanned aerial vehicle; and S5, performing water leakage detection on a sound leakage part on the inner side of the outer window to be detected. According to the rapid detection method, the detection efficiency of external window leakage can be improved.
