Problems solved by technology

[0002] At present, the conservative treatment methods for thoracolumbar fractures include manual reduction, lumbar back pillow, lumbar traction, etc. These conservative treatment methods do not take into account that the vertebral body is a three-dimensional structure, and the force acting in one direction cannot effectively reset the vertebral body fracture ; At present, most of the traction devices are horizontal in the market, and there is a lack of vertical traction equipment for the lumbar spine.
Some devices are improved to vertical traction, but the structure is not suitable, and some traction belts are directly tied to the patient. During the traction process, it will compress the soft tissue around the patient, causing discomfort, unbearable, and difficult to persist, making treatment and rehabilitation difficult. be carried out effectively; in some cases, the direction of traction force is changed or reduced, and effective traction cannot be carried out
The patient is passively involved, the degree of treatment is not enough, and there is no active participation of the patient in the treatment process
In addition, in the middle and late stage of fracture rehabilitation, it is not considered that the exercise of the lumbar and back muscles requires a gradual process, and the lack of an auxiliary lumbar and back muscle exercise system makes the patient's lumbar and back muscles not properly exercised.

Abstract

The invention relates to fracture reduction recovery instruments, in particular to an adjustable thoracolumbar vertebral fracture reduction recovery three-dimensional retractor. An adjustable tension arch device, a binding band, a movable pulley set, a fixed pulley set and a fixing piece are arranged. The adjustable tension arch device is provided with a six-connecting-rod mechanism, a left screw rod, a right screw rod and a central adjusting screw rod. The six-connecting-rod mechanism is provided with a first rod piece, a second rod piece, a third rod piece, a fourth rod piece, a fifth rod piece and a sixth rod piece, the lower end of the first rod piece is in screw joint with the upper end of left screw rod, the lower end of the third rod piece is in screw joint with the upper end of the right screw rod, the two ends of the second rod piece are hinged to the upper end of the first rod piece and the upper end of the third rod piece, the upper end of the fourth rod piece is hinged to the third rod piece, the upper end of the sixth rod piece is hinged to the first rod piece, the two ends of the fifth rod piece are hinged to the lower end of the fourth rod piece and the lower end of the sixth rod piece, the central adjusting screw rod penetrates through the second rod piece and is in threaded fit with the second rod piece, and the lower end of the central adjusting screw rod is movably connected with the fifth rod piece. The binding band is provided with a transverse binding band body, the two sides of the transverse binding band body are connected with the left screw rod and the right screw rod, and the movable pulley set is arranged at the upper end of the central adjusting screw rod. The fixed pulley set is arranged on the fixed piece, and a pull rope is arranged between the moveable pulley set and the fixed pulley set.

Description

Technical field [0001] The invention belongs to a medical device, and relates to a fracture reduction and rehabilitation device, in particular to an adjustable thoracolumbar fracture reduction and rehabilitation three-dimensional traction device. Background technique [0002] At present, conservative treatment methods for thoracolumbar fractures include manual reduction, lumbar back cushion, lumbar traction, etc. These conservative treatment methods do not take into account that the vertebral body is a three-dimensional structure, and a single direction force cannot effectively reduce the vertebral body fracture. ; At present, there are mostly horizontal traction devices on the market and lack of vertical lumbar traction equipment. Some devices are modified to vertical traction, but the structure is not applicable. Some traction belts are directly tied to the patient. During the traction process, the soft tissues around the patient will be compressed, causing discomfort to the pa...
