Embodiment Construction

[0014] The present invention will be further elaborated below in conjunction with embodiment.

[0015] In order to make the purpose and technical advantages of the present invention clearer, the present invention will be described in detail in conjunction with the accompanying drawings.

[0016] An intelligent nail plate system includes a nail plate 1, a piezoelectric detection sheet 2, and a pedicle screw 3, such as figure 1 shown.

[0017] After the patient completes the nail-plate fixation operation, the pedicle screw 3 is fixed on the nail plate 1, and there is a piezoelectric detection piece 2 between the nail plate 1 and the pedicle screw 3. Due to the piezoelectric effect, the piezoelectric The detection piece 2 will generate a potential difference under the action of the pressure between the pedicle screw 3 and the nail plate 1. By detecting and amplifying the voltage and transmitting it to the host computer through the wireless transmission module, the current pedicl...

Abstract

The invention discloses an intelligent screw plate system for a thoracolumbar spine anterior approach and a control method. The intelligent screw plate system is composed of a screw plate 1, a piezoelectric detection piece 2 and a pedicle screw 3. After a patient finishes a screw plate fixing operation, the pedicle screw 3 is fixed on the screw plate 1, the piezoelectric patch 2 is arranged between the screw plate 1 and the pedicle screw 3, and due to the piezoelectric effect, the piezoelectric patch 2 can generate potential difference under the action of pressure between the pedicle screw 3 and the screw plate 1. The current pressure between the pedicle screw and the screw plate can be obtained by detecting and amplifying the voltage and transmitting the voltage to an upper computer through a wireless transmission module, and when the pressure is smaller than a preset threshold value, it can be considered that the current screw is loosened.

Description

technical field [0001] The present invention relates generally to an anterior thoracolumbar intelligent nail-board system and control method, and more particularly to a spine that can be secured to a patient's spine for anterolateral surgical correction of conditions such as scoliosis The process of scoliosis is also called curvature of the spine. Background technique [0002] At present, after the operation on the uncinate vertebral joint of the patient, the nail-plate system is often used to fix the patient's vertebrae. However, as time goes by, the patient's vertebrae may have some displacement, resulting in loosening of the screws, resulting in therapeutic effects. reduce. Threaded fixation elements such as threaded rods or nails, as well as slotted fixation elements of traditional bone fixation devices such as plates or lateral blocks, are often flawed in design because they do not form an exact 90-degree angle , and the nut cannot be securely fastened with the thread...
