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 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.

A model of the human heart for practicing surgical procedures, characterized in that the model replicates the human heart and heart valve and bypass operations can be performed on it.
