This application relates to the field of intelligent cleaning equipment, and provides a control method, device, cleaning equipment, and storage medium for cleaning equipment. The method includes: acquiring contour perception information of an obstacle; determining a target rotation radius for each path planning cycle based on the contour perception information; and controlling the cleaning equipment to move along the contour of the obstacle according to the target rotation radius within each path planning cycle. This solution can improve the stability of the bypass path and the smoothness of the bypass operation.

The present invention discloses a cable upper fixing device for bypass operation, comprising: a clamping component, the clamping component is used to fix with an electric pole, one side of the clamping component is fixedly connected with a support plate; a telescopic component, one end of the telescopic component is fixedly connected to the top of the support plate, and a cross arm is installed at the end of the telescopic component away from the clamping component. The present invention is convenient for fixing the device on the electric pole below the main line by providing a clamping component and a retracting and extending component, and the fixing component used for upper fixing can be sent to the top of the main line after the device is fixed by extending the retracting and extending component, thereby avoiding the problem of inconvenience in crossing the line during the upper pulling process; and a fixing component that is convenient to operate with an insulating rod is provided. In the process of cable fixing, it is only necessary to use the insulating rod to hang the cable in the wire groove on one side of the fixed line block, and then the insulating rod is used to move the fixing seat upward through a pull ring, so that the cable hanging part can be moved to the inside of the fixing seat for fixing.

The application belongs to the technical field of biological medicine, and particularly relates to a pharmaceutical use of a Hedgehog pathway inhibitor in preventing and treating vascular remodeling and restenosis after an arterial bypass operation and improving the survival rate of a coronary heart disease patient after the arterial bypass operation. The abnormal proliferation of smooth muscle cells driven by endothelial cell activation can be obviously inhibited by the Hedgehog pathway inhibitor GDC-0449 intervention, and the inflammatory reaction can be effectively reduced. In the in-vivo experiment, the local application of GDC-0449 to the bypass artery can significantly relieve the remodeling and stenosis of the bypass artery, and provide a theoretical basis and strong support for the molecular targeted treatment strategy of the vascular remodeling and failure after the arterial bypass operation.

The invention discloses a bypass operation fixing device and a bypass system building method. The bypass operation fixing device is mainly composed of a main wire clamp, a lead sleeve and a supporting rod. The main wire clamp and the lead sleeve are insulated through the supporting rod and are fixed at intervals, so that in the using process of the device, it can be guaranteed that the main wire clamp is fixed to a main wire, the lead sleeve and the main wire clamp can be insulated, one end of a drainage wire can be conveniently inserted into the lead sleeve to be fixed to the main wire in an insulated mode, and the service life of the drainage wire is prolonged. Convenience is provided for building a bypass system, current conduction in the operation process can be effectively avoided through the design, and the safety of operators is guaranteed; the bypass operation fixing device is matched with a corresponding building method, operation can be completed only through one insulating boom truck, the equipment investment cost is directly reduced, the complex coordination process during cooperative operation of two trucks is avoided, and the operation efficiency is effectively improved.
