Description

Bracket device for spinal surgery

Technical Field

The invention relates to the technical field of medical instruments, in particular to a bracket device for spinal surgery.

Background

The spinal diseases are that sclerotin, intervertebral disc, ligament and muscle of the spine are diseased, and then the spinal cord, spinal nerves, blood vessels and vegetative nerves are pressed and pulled to stimulate, thereby causing complex and various symptoms. The common diseases include cervical spondylosis and lumbar spondylosis. The main symptoms are: failure to stand upright, headache, vertigo, blurred vision, memory loss, soreness of the neck and shoulders, poor appetite, regurgitation, vomiting, weakness of lower limbs, and paralysis in severe cases.

At present, 97% of middle-aged and elderly people in China have spine diseases, and in recent years, the spine disease tends to be younger, in people under 40 years old, 40% or more of spines of people have various diseases, the incidence rate of scoliosis of children is up to 25% or more, and the spines support the weight of the whole upper half of the body, so when the spines are damaged or diseased, spine operation treatment is needed.

Spine operation all needs to be accomplished on spine operation bracket, but present spine operation bracket mostly all adopts dull and stereotyped bed in the hospital, let patient lie prone in bed, then fill up the cotton method of filling up under patient's belly, but the doctor can slightly adjust patient's backbone radian at the operation in-process, this just needs many medical personnel to lift up patient, then thicken the cotton pad under patient's the belly, adjust the backbone radian with this, still have some backbone operation brackets of adjustable backbone radian, the angle that the accessible manually adjusted arc filled up reaches the effect of adjusting the backbone.

However, the above-mentioned spinal surgery bracket has the following disadvantages:

1. the prior method for adjusting the radian of the spine needs a plurality of people to lift the patient, which not only wastes time and manpower and influences the smooth operation, but also causes unnecessary injury to the patient,

2. the length of the existing spinal surgery bracket is fixed and unchanged, the length can not be adjusted according to the body type of a patient, and the existing spinal surgery bracket can not be suitable for all patients;

3. the existing spinal surgery bracket has single function and simple structure, and other parts except the belly of a patient cannot be supported;

4. because the spine operation time is too long, the patient lies on the operation bracket for a long time, and pressure sores are easily generated at joints of the face, the hands, the legs and the like, so that the patient is injured secondarily;

accordingly, the present invention provides a bracket device for spinal surgery to solve the above problems.
