Orthopedic minimally invasive surgery adjusting and expanding device

Abstract

The invention discloses an orthopedic minimally invasive surgery adjusting and expanding device. The device comprises a fixing sleeve, a first avoidance cavity, fixing shafts, supporting plates, firstsprings, a supporting rod, a limiting contact plate, a second avoidance cavity, a pressing plate, second springs, a sealing cover, an adjusting screw rod, a sealing gas gasket, a regulating valve, agas injection tube and a syringe. The orthopedic minimally invasive surgery adjusting and expanding device is ingenious in structure and powerful in function. Through the mutual cooperation of a rotating expansion mechanism and a supporting mechanism, convenience is provided for medical staff to conduct surgery, and meanwhile expansion of a surgical site of a patient is well achieved. The surgicalfield space is enlarged, ultimately great convenience is brought to subsequent surgical operations, and clinical application and popularization are achieved.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to an orthopedic minimally invasive surgery regulating expansion device. Background technique [0002] Neck and shoulder pain, low back and leg pain are common clinical symptoms, most of which are caused by spinal diseases, and some severe cases require surgical treatment. Since the spine is an important physiological structure of the human body, minimally invasive or non-invasive treatment has become an ideal state pursued by spine surgeons. Minimally invasive surgery of the spine has achieved rapid development in the treatment of spinal diseases. However, due to the complex anatomical structure of the spine and the specificity of individuals, it is difficult to accurately reach the lesion area during surgery. Therefore, minimally invasive surgery of the spine has certain risks. and limitations. [0003] According to the above, in the current clinical operation, it is necessa...

Minimally invasive surgery of the spine has achieved rapid development in the treatment of spinal diseases. However, due to the complex anatomical structure of the spine and the specificity of individuals, it is difficult to accurately reach the lesion area during surgery. Therefore, minimally invasive surgery of the spine has certain risks. and limitations

[0003] According to the above, in the current clinical operation, it is necessary to effectively expand the operative field of the surgical site, that is, to achieve the purpose of improving the surgical operation. However, the current traditional dilator generally has a simple structure and a single function, and has the following disadvantages. Most of the device is a rigid stretching expansion structure, which is easy to damage the wound tissue of the patient during the expansion process, which increases the risk of the patient's operation. In view of the above defects, it is necessary to design an orthopedic minimally invasive surgery adjustment expansion device
