Orthopedic traction device

Abstract

The orthopedic traction device comprises an inner rod, a shell, a driving part and a buffering device, the shell wraps the inner rod, and the driving part is connected to the inner rod and used for driving the inner rod to move relative to the shell in the traction direction. The buffer device comprises a fixed part, a movable part and an elastic part. The fixing piece is connected to the shell; the moving part is connected to the driving part, and the driving part drives the moving part to move in the traction direction, so that the moving part and the fixed part generate relative displacement; one end of the elastic piece is connected to the fixed piece, and the other end of the elastic piece is connected to the movable piece; when the moving part and the fixed part generate relative displacement, the elastic part deforms to buffer the traction force, acting on the inner rod, of the driving part. The buffering device is arranged in the traction device for the orthopedics department, so that the traction force applied to a patient can be effectively buffered during traction in an operation, and the injury to the lower limbs of the patient caused by sudden application of the traction force can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an orthopedic traction device. Background technique [0002] During various operations such as traction, reduction and fixation of the lower limbs, it is necessary to fix the patient's feet, so as to achieve lateral and horizontal lower limb traction, internal rotation and abduction of the patient's limbs during the operation. Posture adjustment needs. The current traction device is rigid traction, the end of the traction device directly acts on the patient's lower limbs, and the operating doctor directly operates the traction handle to pull the patient's lower limbs. [0003] In the prior art, when rigid traction is used to fix the patient's lower limbs, there will be excessive traction on the patient's lower limbs, resulting in the risk of unnecessary strain, and it cannot satisfy the doctor's perception of the traction force. When performing operations such as ex...
