Minimally-invasive thoracolumbar vertebral fracture repositor

Abstract

The invention discloses a minimally-invasive thoracolumbar vertebral fracture repositor. The minimally-invasive thoracolumbar vertebral fracture repositor is formed by a left clamp, a right clamp, regulating nuts, regulating screw rods, a pin, a movable pin, a left clamp handle and a right clamp handle, wherein the left clamp, the right clamp, the left clamp handle and the right clamp handle are integrated, the left clamp handle and the right clamp handle are provided with the regulating screw rods and the regulating nuts, the movable pin is used as a pivot by the left clamp and the right clamp, and two clamp heads are both provided with semi-circle notches. The minimally-invasive thoracolumbar vertebral fracture repositor disclosed by the invention has the characteristics that the structure is reasonable, the surgery is simple, the operation is convenient, the location is accurate, the curative effect is good, the cost is low, the pain of a patient is light, the economical burden is less, and the like; and the problems, such as large surgery wound, long time and great pain of the patient, existing for a long time, are solved, the strut reposition of a fractured vertebral body can be quickly carried out through a minimally-invasive incision channel, the surgery time is saved, the pain of the patient is relieved, the curative effect is obvious, and the minimally-invasive thoracolumbar vertebral fracture repositor is an ideal reposition surgery mating instrument dedicated for minimally-invasive treatment of thoracolumbar vertebral fracture.

Description

technical field [0001] The invention relates to a medical device, in particular to an orthopedic surgical device, a minimally invasive thoracolumbar fracture reducer for treating thoracolumbar fracture reduction operations. Background technique [0002] Thoracolumbar fractures are common spinal fractures. The traditional operation is to fix the fracture site with pedicle screws. Pedicle screws are widely used because of their advantages of three-column fixation. For pedicle screw insertion, it is cut in the middle of the back of the human body and stripped to both sides along the incision. The trauma is large, the bleeding is heavy, and the hospital stay is long, which increases the patient's pain and financial burden; the operation needs to be extended and stripped. Muscles can easily lead to the loss of innervation of the paraspinal muscles, resulting in late dysfunction, and often suffer from complications such as back pain and stiffness. In clinical practice, the existi...

Problems solved by technology

[0002] Thoracolumbar fractures are common spinal fractures. The traditional operation is to fix the fracture site with pedicle screws. Pedicle screws are widely used because of their advantages of three-column fixation. For pedicle screw insertion, it is cut in the middle of the back of the human body and stripped to both sides along the incision. The trauma is large, the bleeding is heavy, and the hospital stay is long, which increases the patient's pain and financial burden; the operation needs to be extended and stripped. It is easy to lead to the loss of innervation of the paraspinal muscles, resulting in late dysfunction, and often suffers from complications such as back pain and stiffness

In clinical practice, the existing pedicle screw instruments are only designed and used in traditional open surgery. The operation is troublesome, the wound is large, and the patient suffers a lot. It is very difficult to introduce the insertion and longitudinal rods, so it cannot be used for multi-segment fixation of thoracolumbar fractures

For the reduction of the spine, only the large incision is opened with forceps, which increases the pain of the patient. Therefore, it is urgent to develop a method for minimally invasive treatment of thoracolumbar fractures. Devices for body expansion and reduction to meet the actual needs of surgery and clinical practice, so as to reduce the pain and economic burden of patients
