Background
In the progress of modern medicine, thoracic spinal stenosis is becoming one of the diseases of great concern. The thoracic spinal canal stenosis is a disease in which the effective volume of the spinal canal is reduced due to various lesions in the thoracic spinal canal, thereby compressing the spinal cord or nerve roots, causing a series of clinical symptoms. The causes of the disease are various, including the herniation of the thoracic vertebrae and the prolapse of the lumbar intervertebral disc, the hypertrophic calcification of the yellow ligament, the ossification of the posterior longitudinal ligament, the formation of the bone tag at the posterior edge of the thoracic vertebrae and the like.
With the increasing population aging and the changing lifestyle of people, the incidence of thoracic spinal stenosis is on the rise. Patients often show weakness, numbness, unstable walking, dysuria and the like of lower limbs, and seriously affect the quality of life. For patients with severe symptoms, where conservative treatment is ineffective, posterior wall resected spinal canal decompression is an important treatment option.
The thoracic vertebrae back wall excision vertebral canal decompression is a complex and fine operation, and aims to remove pathological tissues pressing spinal cord, enlarge vertebral canal volume and restore normal functions of spinal cord. Accurate and safe lifting of the lamina is a vital element during surgery. However, currently used lamina lifting tools face a number of challenges in practical applications.
In conventional surgical procedures, one-handed straight jaws are often used to perform the relevant procedure. However, this straight nose pliers has obvious drawbacks. Due to its design limitations, it is difficult to provide adequate grip stability for one-handed operation. In the operation process, a doctor needs to perform fine operation in a limited and complex operation area, and the straight-mouth forceps are easy to take off due to factors such as sliding, fatigue or external force interference of the spinal plate spinous process.
In addition, the structure and function of the straight nose pliers are not well adapted to the various requirements in the operation. When the lamina is lifted, it does not provide a uniform and stable force distribution, thereby affecting the stability and accuracy of the procedure.
Unstable procedures may result in unnecessary damage to surrounding tissue, increasing the risk of surgery and the incidence of complications. For patients, this may mean longer recovery time, more pain, and potential health risks.
Meanwhile, due to the defect of the straight tongs, doctors need more energy and time to control tools in the operation, so that the operation difficulty of the doctors is increased, and the operation efficiency and effect can be influenced.
