Problems solved by technology

[0004] In order to avoid the above-mentioned technical problems, the invention patent with the patent number "2017208414841" discloses a transverse connector for spinal fixation. This patent optimizes the design of the hook seat so that the groove opening on the hook seat faces outwards and downwards. Thereby reducing the wound, however, the hook seat in this patent adopts an integrated design, the opening of the groove is not flexible, and the adaptability to connecting rods of different specifications is poor

Abstract

The invention relates to a clamping groove adjustable type universal horizontal connecting machine. The clamping groove adjustable type universal horizontal connecting machine comprises a connecting system located at the middle and two sets of clamping systems at two ends of the connecting system, wherein each clamping system comprises a clamping jaw and a locking block; each locking block is connected with the corresponding clamping jaw through locking screws; one locking block and the corresponding clamping jaw form a clamping groove; the locking screws are regulated to enable each locking block to move so as to regulate the opening size of the corresponding clamping groove; and one end away from the clamping groove, of each clamping system is connected with the connecting system. Each locking block movably connected to the inner part of the corresponding clamping jaw and the corresponding clamping jaw jointly form the corresponding clamping groove, and the relative positions of eachlocking block and the corresponding clamping jaw are adjusted through the corresponding locking screws, so that the size of the corresponding clamping groove is flexibly adjusted; and the opening size of each clamping groove is adjusted, so that the clamping grooves of the horizontal connecting machine can be adapted to connecting rods of different specifications, and the mounting is convenient.

Description

technical field [0001] The invention relates to a horizontal connector, in particular to a slot-adjustable universal horizontal connector. Background technique [0002] In spinal injury surgery, spinal fixators are usually used to fix the spine. The spinal fixator is composed of a screw-rod system and a transverse connector. A connecting rod connected in series by two pedicle screws, the connecting rod replaces the damaged spine to support the human body, since there are pedicle screws and connecting rods on both sides of the spine, in order to avoid connecting rods and pedicle screws on both sides of the spine Uncontrollable displacement occurs, resulting in damage to the vertebrae. Therefore, a transverse connector is usually used to connect the two connecting rods together, so that the screw-rod systems on the left and right sides of the spine are connected into one, improving the stability of the spinal fixator and ensuring Therapeutic effect on the spine. [0003] The...
