C-arm machine rotary scanning movement cable automatic tensioning device

Abstract

The invention discloses a C-arm machine rotary scanning movement cable automatic tensioning device, belonging to the technical field of medical instrument movement equipment. The device comprises a tension wheel, a tension wheel shaft, a spring connecting rod, a tension rod and a tension bracket. The tension wheel is internally equipped with a hole retainer ring, a bearing and a baffle ring. A shaft retainer ring A is arranged under the tension wheel shaft. The spring connection rod is provided with multiple springs and multiple spring connection pins, and each of the springs is correspondingly connected to a spring connection pin. The tension rod is installed on the tension bracket through a gasket, a rotary pin and a shaft retainer ring B. The tension wheel is connected to a steel wire rope which acts on the tension wheel. The tensioning force of the steel wire rope is adjusted through the deformation of the springs, and thus the tensioning force of a movement cable row is adjusted. The C-arm machine rotary scanning movement cable automatic tensioning device has the advantages of a simple structure, convenient assembly and disassembly, low cost and high reliability, the tensioning force of the cable row can be effectively adjusted, the cable row is constantly protected from being damaged, and the device has the advantages of the simple structure, convenient assembly and disassembly, low cost and high reliability.

[0002] With the rapid development of medical technology, clinical applications have higher and higher requirements for medical device mobile equipment. The design of hiding cables in the mechanical structure will become the mainstream trend of medical mobile C-arm machines. Automatic cable tensioning devices are not available. What is missing, at present, in the Chinese patent application number CN201120131312.8, a cable tensioning device is disclosed. The sliding plate, the fixed plate and the cylindrical guide are relatively stationary, and the sliding plate and the cylindrical guide are relatively slidably sleeved on the outer periphery of the cylindrical guide; the elastic member is sleeved on the cylindrical guide and is limited between the fixed plate and the cylindrical guide. Between the sliding plates; the cable pipe clamp is connected with the fixed plate or the sliding plate, and the opening direction of the cable pipe clamp is perpendicular to the expansion and contraction direction of the elastic member; the cable tensioning device uses the compression deformation of the elastic member to absorb the impact force on the cable , so that the pulling force of the cable can be buffered, forming a protection for the cable, and the position of the cable tube clamped on the cable can be adjusted in real time; When the situation occurs, especially the C-arm of the X-ray machine needs to protect the cable row at all times during the rotation and scanning movement, and the tension of the cable row cannot be effectively adjusted.
