C-arm machine rotation scanning motion cable automatic tensioning device

Abstract

The invention discloses a C-arm machine rotation scanning motion cable automatic tensioning device which comprises a bottom plate and a tensioning box. The tensioning box is fixedly installed at the top of the bottom plate, guide boxes are fixedly installed at the two sides of the tensioning box respectively, and the two guide boxes are each of a structure with the two sides open. An air cylinder is fixedly mounted in the middle of the top of the inner side of the tensioning box, a pneumatic telescopic rod is arranged at the output end of the air cylinder, and a first mounting plate is fixedly mounted at the bottom end of the pneumatic telescopic rod; mounting through holes are formed in the four ends of the interior of the first mounting plate, and movable rods are movably mounted in the four mounting through holes. A second mounting plate is fixedly mounted at the bottom ends of the four movable rods, a second roller frame is fixedly mounted at the bottom of the second mounting plate, and a tensioning roller is movably mounted at the bottom of the second mounting plate through the second roller frame. By arranging a series of structures, the tensioning device has the advantages of being capable of preventing the cable from deviating in the moving process and being good in tensioning effect.

Description

technical field [0001] The invention relates to the technical field of a C-arm machine, in particular to an automatic tensioning device for a C-arm machine rotating scanning motion cable. Background technique [0002] The C-arm machine is a mobile X-ray machine that integrates light, machine, and image processing technologies. It is generally composed of a high-voltage generator, an X-ray tube, an operation control system, and a display. The imaging of the C-arm X machine is a two-dimensional image, intuitive and clear, easy for surgeons to grasp, and easy to promote and use. In order to cooperate with operations on different parts of different patients, the C-arm X machine commonly used in orthopedics is a bedside mobile type, which has played a unique role in orthopedic surgery positioning, inspection of reduction effects, and minimally invasive surgery. [0003] Because the C-arm machine is easy to adjust in different angles, the cables used to connect the various compon...

Problems solved by technology

[0003] Because the C-arm machine is easy to adjust in different angles, the cables used to connect the various components will also move with the movement of the components on the C-arm machine, and then it is essential to tension the cables on the C-arm machine, but now Some tensioning devices are mostly simple in structure, unable to position the cable to prevent its deviation, and cannot buffer the tension force during the tensioning process, which is easy to damage the cable. Therefore, in order to solve this series of problems we A C-arm machine rotary scanning motion cable automatic tensioning device is proposed to solve the problem
