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 technique

Spondylosis is the disease of the bones, intervertebral discs, ligaments, and muscles of the spine, which in turn compresses and stimulates the spinal cord, spinal nerves, blood vessels, and autonomic nerves, resulting in complex and diverse symptoms. Common diseases are cervical spondylosis and lumbar spondylosis. Main symptoms: unable to stand upright, headache, dizziness, blurred vision, memory loss, neck and shoulder pain, loss of appetite, nausea, vomiting, weakness of lower limbs, and severe cases may lead to paralysis.

At present, 97% of the middle-aged and elderly people in my country suffer from spinal diseases. In recent years, there has been a trend of younger people. Among the people under the age of 40, more than 40% of them have various diseases in the spine. The incidence of scoliosis in children The incidence rate is as high as more than 25%. The spine supports the weight of our entire upper body. Therefore, when the spine is damaged or pathological changes occur, spinal surgery is required.

Spinal surgery needs to be completed on a spinal surgery bracket, but most of the existing spinal surgery brackets in the hospital use a flat bed, let the patient lie on the bed, and then put a cotton pad under the patient's stomach, but the doctor During the operation, the curvature of the patient's spine will be slightly adjusted, which requires multiple medical staff to lift the patient, and then thicken the cotton pad under the patient's stomach to adjust the curvature of the spine. The spine surgery bracket can achieve the effect of adjusting the spine by manually adjusting the angle of the arc pad.

But there is following drawback in above-mentioned spinal surgery bracket:

1. The existing method of adjusting the radian of the spine requires multiple people to lift the patient, which not only wastes time and manpower, affects the smooth progress of the operation, but also causes unnecessary harm to the patient.

2. The length of the existing spinal surgery bracket is fixed, and the length cannot be adjusted according to the patient's body shape, so it cannot be applied to all patients;

3. The existing spinal surgery bracket has a single function and a simple structure. Except for the support on the patient's stomach, the rest of the bracket cannot support;

4. Due to the long time of spinal surgery, the patient lies on the surgical bracket for a long time, and pressure sores are prone to occur on the face, hands, legs and other joints, causing secondary damage to the patient;

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

During the specific operation, when the length of the bed board does not need to be adjusted, at this time, the spreader motor 22 is turned forward, and the spreader half-gear 20 simultaneously drives the lifting gear 12 and the spreader driving bevel gear 45 to rotate, and the lifting bed board 10 begins to rise, and the When the spreader transmission mechanism 24, the left spreader 18 and the right spreader 19 rise upwards from the spreader placement groove 17, and at the same time through the cooperation of the spreader rack 43 and the spreader translation half gear 44, the left spreader 18 and the right stay Plate 19 draws closer to the middle while rising, and now the winding wheel 58 on the rotating shaft of right support plate 19 rotates and begins to take up wire 68, so that leg massage disc 64 can move to the corresponding position with the rising of right support plate 19, When the left spreader 18 and the right spreader 19 move closer to the middle and fit together, stop the spreader motor 22. At this time, the lifting bed board 10 is still under the upper body bed board 2 and the lower body bed board 3. If it is necessary to slightly adjust the radian of the spine at this time, It only needs to be realized by raising and lowering the height of the left spreader 18 and the right spreader 19. After the use is over, start the spreader motor 22 in reverse, and the left spreader 18 and the right spreader 19 will drop into the spreader placement groove 17, and the bed board will be raised and lowered. 10 also descends to the elevating bull gear 12 tops thereupon.

If the length of the bed board needs to be adjusted, the bed board motor 8 is turned forward at first, and the bed board motor 8 drives the lifting half gear 13 to rotate, and the bed board translation gear 6 is rotated by the bed board transmission mechanism 7. At this time, the upper body bed board 2 moves to the left, and the lower body bed board 3 Move to the right, the lifting half gear 13 drives the lifting gear 12 to rotate, and the lifting screw rod 9 drives the lifting bed board 10 to move upward. The upper body bed board 2 and the lower body bed board 3 are in the middle, and are fitted with the upper body bed board 2 and the lower body bed board 3 to form a longer bed board; at this time, turn forward and start the spreader motor 22 to make the left spreader 18 and the right spreader 19 rise and Move in the middle of the phase, at this time the spreader half gear 20 rotates to drive the lifting gear 12 to rotate, and the lift screw 9 continues to move upward with the lift bed 10, when the lift bed 10 moves to the left spreader 18 and the right spreader 19, and After fitting the left brace 18 and the right brace 19, stop the brace motor 22. If you need to slightly adjust the height of the spine at this time, you only need to adjust the height of the left brace 18, the right brace 19 and the height of the lifting bed board 10, that is The radian of the spine can be adjusted slightly. After use, reverse and turn on the spreader motor 22 first, so that the left spreader 18 and the right spreader 19 drop into the spreader placement groove 17, and the lifting bed board 10 also descends to the upper body bed board 2 and the lower body bed board 3 in the middle, then turn on the bed board motor 8 in reverse to make the lifting bed board 10 continue to descend, while the upper body bed board 2 and the lower body bed board 3 move to the middle at the same time, and finally return to the state before use.

The present invention achieves the effect of quickly adjusting the radian of the patient's spine during the operation through the liftable support board, saves time and effort, and will not affect the operation process; through the movable and adjustable bed board, it can be used by patients of various sizes; Through the head massager, hand massager and leg massager, it relieves the patient's pressure sore caused by long-term oppression during the operation, and also provides the patient with a comfortable spinal surgery bracket.
