A spreading mechanism for orthopedic spine surgery tissue

Abstract

The present invention relates to the technical field of medical appliances, in particular to a stretching mechanism for orthopedic spinal surgery tissue, which includes a first support plate, a second support plate, a delivery tube and a threaded push rod, and the two ends of the first support plate are hinged with The two ends of the second support plate are hinged with push-pull rods, the other end of the push-pull rod is hingedly installed on the front end of the bar-shaped through groove, and the front end of the spread rod is equipped with a spread arm, and the bottom of the spread arm is provided with a through holes, and the bottom is also provided with several groups of evenly spaced annular bodies, the free end of the delivery pipe is exposed, the other end runs through the front end of the support arm, and extends from the adjustment rod to the bottom through hole in the spread arm. In the present invention, only one integrated device can maintain the stretched state of the incision at the spine for a long time without loosening. Effectively absorb the effusion in the incision, simplify the operation and improve the safety.

Description

Technical field[0001]The invention relates to the technical field of medical appliances, in particular to a bracing mechanism for orthopedic spinal surgery tissue.Background technique[0002]Spondylopathies are diseases of the bones, intervertebral discs, ligaments, and muscles of the spine, which compress and traction to stimulate the spinal cord, spinal nerves, blood vessels, and autonomic nerves, resulting in complex and diverse symptoms.[0003]Common diseases are cervical spondylosis and lumbar spondylosis. Main symptoms: Inability to stand upright, headache, dizziness, blurred vision, memory loss, neck and shoulder pain, loss of appetite, nausea, vomiting, weakness of lower limbs, severe cases may lead to paralysis.[0004]When surgery is used clinically in the prior art for treatment, such asfigure 1 As shown, at the spine 19, the skin of the patient is cut to expose the spine 19, and then another doctor or nurse is needed to assist the incision to open a certain opening, which is ...

AI Technical Summary

Problems solved by technology

[0004] When using surgery in the prior art to treat clinically, such as figure 1 As shown, at the spine 19, the skin of the patient is cut open to expose the spine 19, and then another doctor or nurse is needed to assist the incision to open a certain mouth, which is convenient for the doctor to perform the operation. However, the operation time of the spine is several hours, and the operation time is long. , the stretched incision needs to be kept in one posture for a long time, which is very easy to cause fatigue, and there are touches and shakings during the operation, which can shrink the stretched incision, which will affect the doctor's operation or the realization of the operation , which exacerbates the risk of surgical failure

[0005] If the incision becomes smaller and then expanded, it may cause a surge of blood in the patient's spine and affect the operation. Moreover, due to the tissue effusion that is likely to occur during the operation, if other negative pressure devices are used to attract it, it will affect the efficiency and progress of the operation. Since the effusion is produced slowly, it cannot be sucked in real time when it is less than a certain amount
