Description
[technical field]
This utility model relates to field of medical, especially relates to a kind of device separating for fixing sacroiliac joint.
[background technology]
Known, traumatic pelvic ring injuries causes sacroiliac joint separation to cause that pelvis is vertical or rotate unstable, this type of damage need to be carried out internal fixation operation treatment conventionally, but because of the position of sacroiliac joint dark, stopping of important anatomy structure (waist 4 nerve rooies) around, it is very limited that the rumpbone side of sacroiliac joint can be provided for laying the position of screw, and the dissection of sacro-iliac joints and comparatively complexity of biomechanics, therefore sacroiliac joint separating operation is treated very complexity, the common method for the treatment of clinically sacroiliac joint separation at present has double steel plate to fix, sacrum rod is fixing to be fixed with sacroiliac joint screw, but all there is certain drawback, double steel plate fixedly exists the poor drawback of ability of anti-torsion and anti-separation, sacroiliac joint screw is fixing has higher requirement to operation technique and operating room equipment, a lot of hospitals are difficult to carry out, and be only applicable to sacroiliac joint shift separation and slightly or obtain the good patient who resets, for displacement obviously or the not good patient that resets cannot adopting said method, sacrum rod is fixing fixing strong not, and can cause the separation of front ring when pressurization, thereby causes the state of an illness further to worsen.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of device separating for fixing sacroiliac joint, this utility model is by between the first fixing head and the second fixing head, linking arm being set, thereby reaches the object of fixing sacroiliac joint.
In order to realize described goal of the invention, this utility model adopts following technical scheme:
A kind of device separating for fixing sacroiliac joint, comprise the first fixing head, the second fixing head and linking arm, the first fixing head and the second fixing head are set in parallel in same level, the first fixing head is connected by linking arm with the second fixing head, on the first fixing head and the second fixing head, be equipped with fixing hole, one side of the first fixing head and the second fixing head is equipped with a groove, and two grooves and linking arm are arranged in a linear.
The edge of described fixing hole is slope shape structure, is equipped with two fixing holes at the first fixing head and the second fixing head.
Described the first fixing head and the second fixing head are rectangle structure, and four jiaos of the first fixing head and the second fixing head are convex structure.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
A kind of device separating for fixing sacroiliac joint described in the utility model, comprises the first fixing head, the second fixing head and linking arm, by between the first fixing head and the second fixing head, linking arm being set, thereby reaches the object of fixing sacroiliac joint; A kind of device separating for fixing sacroiliac joint described in the utility model, simple in structure and practical, be more suitable for the implant that sacroiliac joint separates, for great effect has been played in patient's rehabilitation.
[brief description of the drawings]
Fig. 1 is perspective view of the present utility model;
In figure: 1, the first fixing head; 2, linking arm; 3, the second fixing head; 4, groove; 5, fixing hole.
[detailed description of the invention]
Explanation this utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protect all technological improvements within the scope of this utility model.
A kind of device separating for fixing sacroiliac joint described in 1 by reference to the accompanying drawings, comprise the first fixing head 1, the second fixing head 3 and linking arm 2, the first fixing head 1 and the second fixing head 3 are set in parallel in same level, the first fixing head 1 is connected by linking arm 2 with the second fixing head 3, on the first fixing head 1 and the second fixing head 3, be equipped with fixing hole 5, one side of the first fixing head 1 and the second fixing head 3 is equipped with 4, two grooves of a groove 4 and is arranged in a linear with linking arm 2; The edge of described fixing hole 5 is slope shape structure, is equipped with two fixing holes 5 at the first fixing head 1 and the second fixing head 3; Described the first fixing head 1 and the second fixing head 3 are rectangle structure, and four jiaos of the first fixing head 1 and the second fixing head 3 are convex structure.
Implement a kind of device separating for fixing sacroiliac joint described in the utility model, in use, first determine the size of fixing head, then the first fixing head 1 and the second fixing head 3 are placed on to patient's sacroiliac joint place, and insert fixing hole 5 by screw the first fixing head 1 and the second fixing head 3 are fixed, and groove on the first fixing head 1 and the second fixing head 3 not only makes patient more comfortable, and can well adjust fixing head, increase fixing head anti-torsion and anti-shearing separation, be more suitable for the implant that sacroiliac joint separates.
This utility model does not describe part in detail for prior art.
