High-safety fracture traction device and traction detection method

Abstract

The invention relates to a fracture traction device, in particular to a high-safety fracture traction device and a traction detection method. The high-safety fracture traction device comprises a traction bow, a rope walking mechanism, a counterweight device and an angle sensing system, and metal needles used for being inserted into fracture parts are arranged at the two ends of the traction bow; the rope walking mechanism is used for guiding a traction rope, and one end of the traction rope is connected with the traction bow through a first safety hook; the counterweight device is used for providing force required by traction, and the counterweight device is connected with the other end of the traction rope; and the angle sensing system comprises angle sensors, a microprocessor, a display screen and an upper computer, the angle sensors are arranged at all parts of the traction rope at intervals and collect angle signals of the direction of the traction rope, the microprocessor is used for processing analog quantity output by the angle sensors and transmitting the analog quantity to the display screen and the upper computer, and when the angle deviation exceeds a threshold value, the nurse adaptively adjusts the angle of the traction rope and the weight of the weights according to the alarm of the nurse station upper computer.

Description

technical field [0001] The invention relates to a fracture traction device, in particular to a fracture traction device with high safety and a traction detection method. Background technique [0002] The tractors used in various hospitals for lower extremity fracture patients mainly include traction ropes and pulleys. One end of the traction rope is connected to the bracket at the fracture site, and the other end bypasses the pulleys to hang weights. The number of weights can be manually increased or replaced. weight to control traction. Because the patient will move while lying on the hospital bed, the traction force will change. Once the traction force changes, the weight of the weight should be adjusted. For the existing manual control method, frequent replacement of weights is extremely inconvenient, which not only increases the burden on the work of hospital nurses, but also brings trouble to the reset of fractured patients, and the existing counterweight device does n...

AI Technical Summary

Problems solved by technology

For the existing manual control method, frequent replacement of weights is extremely inconvenient, which not only increases the burden on the work of hospital nurses, but also brings trouble to the reset of fractured patients, and the existing counterweight device does not have a protective device for The counterweight device is protected, and it is vulnerable to external interference, which affects the stability of the counterweight. There is no device to detect the straight line state between the traction rope, the counterweight device and the fixed bracket, and there is no accurate detection after the deviation occurs. , affecting fracture recovery, in view of this, we propose a highly safe fracture traction device and traction detection method
