Problems solved by technology

However, its high equipment cost affects the important factor that it cannot be popularized in most hospitals in China.
Some scholars have also designed a series of percutaneous sacroiliac screw-guided devices, which are still difficult to popularize because they are individualized and difficult to operate.
[0005] To sum up, there is currently no simple and accurate S1 sacroiliac screw-guiding device that utilizes body surface bony landmarks for positioning, can be used for both men and women, and can be used for both left and right sides.

Embodiment Construction

[0032] The present invention will be further described below with reference to the drawings and embodiments.

[0033] Such as figure 1 with figure 2 The shown minimally invasive S1 sacroiliac joint screw positioning guide includes a sliding guide 1, a first positioning rod 2, a second positioning rod 3, an anterior superior iliac spine positioning rod 11, a posterior superior iliac spine positioning rod 12, S1 Spinous process positioning needle 14, S1 sacroiliac screw sleeve 7, first guide buckle 4 (for men) and second guide buckle 5 (for women), of which,

[0034] One ends of the first positioning rod 2 and the second positioning rod 3 are cross-connected on the same side of the two ends of the sliding guide rail 1;

[0035] The anterior superior iliac spine positioning sleeve rod 11 is provided at the other end of the first positioning rod 2, and the posterior superior iliac spine positioning sleeve rod 12 is provided on the second positioning rod 3, and extends to the middle to t...

Abstract

The invention discloses a minimally invasive S1 sacroiliac joint screw positioning guide, which is characterized in that it comprises a sliding guide rail (1), a first positioning rod (2), a second positioning rod (3), and an anterior superior iliac spine positioning sleeve Rod (11), Posterior Superior Iliac Spine Positioning Sleeve Rod (12), S1 Spinous Process Positioning Needle (14), S1 Sacroiliac Screw Sleeve (7), First Guide Buckle (4) and Second Guide Buckle ( 5). It is universal, easy to operate and easy to master. It uses the constant law between bony landmarks to locate, does not change with the change of body position during operation, reduces operation time, reduces the number of perspectives, and reduces the learning curve.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and specifically relates to a minimally invasive S1 sacroiliac joint screw positioning guide. Background technique [0002] In pelvic fractures, injuries involving the posterior ring of the pelvis are not uncommon, such as sacroiliac joint dislocation and sacral fractures. Such fractures often lead to pelvic instability, and there are pointers for surgical treatment. For the injury of the posterior pelvic ring without significant displacement or reduction, sacroiliac joint screw therapy has gradually been widely recognized in clinical practice, and some scholars have supported the stability of the technique through biomechanical test results. [0003] In the percutaneous sacroiliac screw technique, the S1 vertebral body screw placement technique is the most commonly used and relatively safe. Due to the complex anatomical structure of the posterior ring of the pelvis, there are important nerve ...
