Spreading mechanism for tissue during spinal operation of orthopedic department

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a spreading mechanism for tissue during a spinal operation of the orthopedic department. The spreading mechanism comprises a first support plate, a second support plate, conveying tubes and a threaded push rod; support arms are hinged to the two ends of the first support plate, push-pull rods are hinged to the two ends of the second support plate, the other ends of the push-pull rods are hinged to the front ends of strip-shaped through grooves, and spreading arms are installed at the front ends of spreading rods; through holes are formed in the bottom of each spreading arm, several uniformly-spaced annular bodies are further arranged at the bottom of each spreading arm, the free ends of the conveying tubes are exposed, and the other ends of the conveying tubes penetrate through the front ends of the support arms, and stretch into the through holes in the bottoms in the spreading arms from the interiors of adjusting rods. According to the spreading mechanism, the spreading state of an incision at a spine can be kept for a long time without looseness simply through an integrated tool, after spreading, the operation view is great, specially-assigned persons for implementation are not needed, and a doctor can implement the operation by himself / herself; meanwhile, hydrops in the incision can be effectively sucked in real time, the operation is simplified, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a stretching mechanism for orthopedic spine surgery tissues. Background technique [0002] 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. [0003] 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. [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 c...

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
