Description

Movable severe spinal deformity traction device

Technical Field

The invention relates to the field of medical appliances, in particular to a movable severe spinal deformity traction device.

Background

Adolescent idiopathic scoliosis (adolescent idiopathic scoliosis, abbreviated AIS) is one of the most common scoliosis deformities that occur during adolescence. AIS has a prevalence of 1% to 3% in the 1-16 year old at risk population, accounting for about 74.7% of all scoliotic patients. The AIS causes scoliosis and distortion of the patient, and chest deformation, affects the cardiopulmonary function and the body appearance of the patient, and reduces the life quality of the patient, thereby seriously endangering the physical and mental health of teenagers. Thus, the treatment of AIS is an extremely important part of orthopedic spinal surgery.

In the 60 s of the 20 th century, there was a traction device for head harnesses and pelvis harnesses, and then a traction device for achieving traction by using body weight as traction force and by means of external tools such as beds, wheelchairs, and the like. The traction of the hair basin ring is exactly one of the effective surgical modes for slowing down the curvature increase before operation. Early head basin ring traction is very important for severe scoliosis orthopedic surgery, and the flexibility of the severe abnormal spine is changed through traction.

The scoliosis patient needs to carry out cervical vertebra long-term traction, and the existing tractor has the following defects:

1. the universal adaptability is poor, and the movable holes are smaller after assembly;

2. the head is not movable after being fixed, and neck stiffness is easy to cause;

3. the patient cannot lie on the bed, and the occupation of the back of the neck of the device is serious;

4. the traction can be carried out by disassembling the assembly, and the operation is inconvenient.

5. Traction needs to lie in a hospital for a long time, takes three months or even one year, has a long period, and needs long-term nursing of medical staff and family members. For long-term traction, stiffness can occur in the neck and spine, cervical complications such as pain and stiffness often occur after surgery, and cervical dislocation can occur entirely due to the persistence of stiffness.

6. The anesthesia intubate is the nose and inserts, and traditional head is the outer frame of movable regulation and need dismantle just can conveniently lean back the neck and realize the intubate.
