Problems solved by technology

In the process of clinical application, there are the following defects: the traditional domino notch is too large, the body is bulky, the local bone and soft tissue are stimulated, and the patient may have a foreign body sensation after operation
In the actual application of clinically more complex orthopedic surgery, due to the influence of factors such as angle and position, it is necessary to repeatedly shape and bend the titanium rod, which makes the operation of placing the traditional domino connector more complicated and difficult, and increases the operation time.

Abstract

The invention relates to a domino connection system. The domino connection system comprises titanium rods, wherein the titanium rods comprise a first titanium rod and a second titanium rod; a pedicle screw used for fixing the titanium rod and the spine; a domino connector which comprises a first arm and a second arm which are located in the same plane, wherein the included angle between the first arm and the second arm is larger than 90 degrees and smaller than 180 degrees, and the first arm is provided with a through hole which is through front and back; the second arm is provided with a front-back through groove, and a top opening of the groove is formed in the top of the second arm. The first titanium rod is fixedly contained in the through hole, and the second titanium rod is fixedly contained in the groove. According to the scheme, the limitation of connecting the domino system with the titanium rod is reduced, and the size of the domino connector is small.

Description

technical field [0001] This patent belongs to the technical field of medical devices, and specifically relates to a domino connection system. Background technique [0002] Scoliosis is a three-dimensional deformity that includes sequential abnormalities in the sagittal, coronal, and axial planes. Severe scoliosis will affect the growth and development of infants and adolescents, and deform the body. In severe cases, it may affect the cardiopulmonary function, and even involve the spinal cord, resulting in paralysis. In the method of treating scoliosis, surgical treatment is one of the important means to correct severe scoliosis. Through posterior internal fixation of the spine, the original physiological curvature of the spine can be restored, thereby treating scoliosis. In the posterior spinal internal fixation, in some cases, surgery is required to extend the original fixed connecting rod to increase the range of fixation, or to bridge the titanium rods of the adjacent u...
