Drawings
FIG. 1 is a rear view of the sacroiliac guide for middle-level surgery of the present invention;
FIG. 2 is a schematic top view of a sacroiliac guide for a middle surgical use of the present invention;
in the figure: a plate body 1; a concave hole 2; a central positioning rod 3; a guide hole 4 is positioned on the posterior superior iliac spine; a guide hole 5 is positioned at the posterior inferior iliac spine; sacroiliac screw holes 6.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1-2, a surgical sacroiliac guide comprises a plate body 1 of a predetermined size for surrounding the back waist of a patient; the plate body 1 is made of flexible material;
the plate body 1 is in a symmetrical arc structure protruding backwards; two sides of the plate body 1 are provided with sacroiliac screw guide holes 6 extending backwards; the sacroiliac screw guide hole 6 is of a hollow cylinder structure provided with internal threads;
the middle part of the plate body 1 is also connected with a central positioning rod 3 which is vertical to the plate body 1 and the front end and the rear end of which extend out of the plate body 1; the front end of the central positioning rod 3 is used for abutting against the fifth lumbar vertebra spinous process of the patient.
Preferably, the plate body 1 is further connected with a pair of symmetrically arranged posterior superior iliac spine positioning guide holes 4 and/or posterior inferior iliac spine positioning guide holes 5;
the posterior superior iliac spine positioning guide hole 4 and the posterior inferior iliac spine positioning guide hole 5 are hollow cylinder structures which are vertical to the plate body 1 and the front end and the rear end of which extend out of the plate body 1.
Preferably, the sacroiliac screw guide hole 6, the posterior superior iliac spine positioning guide hole 4 and the posterior inferior iliac spine positioning guide hole 5 are all provided with internal threads.
Preferably, the plate body 1 is further provided with a plurality of hollowed-out through holes.
Preferably, the plate body 1 is made of PLA material, so that the plate body 1 can deform to some extent to meet the actual requirements without having too low strength.
Wherein the included angle between the direction of the sacroiliac screw (and the central axis of the sacroiliac screw guide hole 6) and the plane of the connecting line of the posterior superior iliac spines on both sides of the horizontal position is 11-13 degrees, and the distance between the front edge of the sacrum and the sacrum hole is 7-17 mm.
The utility model discloses during the use, go on according to following step:
① intestinal tract preparation before operation, anesthesia modes such as general anesthesia, combined anesthesia of lumbar vertebra and lumbar vertebra are adopted for all cases according to the serious conditions of patients and the complexity of fracture, and the operation position is standard prone position
② determining central axis of patient, placing marked kirschner wire in vitro, determining fifth lumbar vertebra spinous process in perspective, making 1cm incision on the fifth lumbar vertebra spinous process, placing the positioning rod of the fifth lumbar vertebra spinous process on the guide plate, driving in the kirschner wire for fixation, superposing the central axis of the guide plate with the central axis of the patient, sequentially driving in the positioning rods of the posterior superior iliac spines at both sides for fixation, verifying stability of the guide plate, and driving in the posterior inferior iliac spines for positioning the kirschner wire if necessary
