Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, wherein the same reference numerals in the drawings denote the same or similar components.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
FIG. 1 is used to illustrate the structure of one exemplary embodiment of an integrated cross-link assembly. Referring to fig. 1, the integral cross-link includes a connector 10 and a set of fasteners 20.
The connector 10 has a connection hole 12 formed through its body in a first direction D1 for receiving a spinal rod to be re-implanted. The connector 10 is provided with a clamping portion 16 along a side perpendicular to the first direction D1, and the clamping portion 16 is provided with an opening for clamping a spinal rod that has been implanted in a body.
In the exemplary embodiment shown in fig. 1, the connecting element 10 is further provided with a first through-hole 14 communicating with the connecting bore 12 and a second through-hole 18 communicating with the clamping portion 16. The axis of the first through hole 14 is perpendicular to the first direction D1. The axis of the second through hole 18 is in the same plane as the axis of the first through hole 14. And the second through-hole 18 gradually approaches the first through-hole 14 from the opening at the clamping portion 16 to the opening at the surface of the connector 10. That is, the second through hole 18 is inclined to the first through hole 14, the specific inclination angle depends on the use position in the spinal column, and the direction of the second through hole 18 is selected to reduce the injury to the paravertebral soft tissue and enable the surgeon to look directly at the installation position for convenient installation.
In the exemplary embodiment shown in FIG. 1, the set of fasteners 20 includes a first fastener 22 and a second fastener 24. The first fastening member 22 is detachably disposed in the first through hole 14, and the length of the first fastening member 22 is longer than that of the first through hole 14, so as to fix the spinal rod inserted into the connecting hole 12, thereby ensuring stable and reliable connection. The second fastening member 24 is detachably disposed in the second through hole 18, and the length of the second fastening member 24 is also longer than the length of the second through hole 18, so as to fix the spinal rod clamped by the clamping portion 16, thereby ensuring stable and reliable connection.
FIG. 2 is a sectional view illustrating one exemplary embodiment of the integrated cross-connect assembly of FIG. 1. Referring to fig. 2, the inner walls of the first and second through holes 14 and 18 are provided with internal threads. The first and second fasteners 22 and 24 are tail cap screws and are threadedly coupled to the first and second through holes 14 and 18, respectively, thereby facilitating intraoperative mounting and fixation.
In the exemplary embodiment, the integral transverse connection assembly is made of titanium alloy to ensure the stability and excellent biocompatibility of the device.
