Background
A periacetabular osteotomy (PAO), a burney periacetabular osteotomy, also known as Ganz periacetabular osteotomy, is a commonly used reconstruction acetabular technique, and is originally proposed in 1988 by switzerland physicians ReinholdGanz and jeffrey mask, polygonal osteotomy is performed around acetabulum, acetabulum is separated from the surrounding pelvis, the intercepted acetabulum can be moved greatly, so that the coverage of the femoral head is corrected to a greater extent, the osteotomy surface can be contacted in a large area to facilitate healing, a continuous posterior pelvic column is maintained, pelvic stability after osteotomy is provided, early partial weight bearing can be achieved, the intercepted white segment is large, and the risk of ischemic necrosis is obviously reduced.
FIG. 1 is a schematic view of the human pelvis structure; fig. 2 is a schematic structural diagram of a pelvis after a periacetabular osteotomy is performed, and referring to fig. 1 and 2, in general, in the operation process, for a pelvis 1 of a patient, an iliac branch 11 and a pubic branch 12 of a hip joint need to be completely cut off, and ischial branches 13 need to be cut off by 2/3, so that the requirement on precision during an osteotomy operation is high, and particularly the requirement on the depth of an incision needs to be accurate.
With the development of science and technology, before the existing operation process, a 3D printing technology is usually adopted to print a model of a hip joint corresponding to a patient according to the actual situation of the patient to perform preoperative osteotomy scheme analysis, and then a doctor is assisted to control an osteotomy position in the operation process by means of a movable C-shaped arm X-ray machine, a liftable perspective bed and other equipment. In the existing conditional big hospitals, before the acetabulum periphery osteotomy is performed, a 3D printing technology is generally used to obtain a model of a pelvis by 3D printing on a pelvis part of a patient needing the acetabulum osteotomy operation, and then an osteotomy scheme is analyzed before an operation, and then an experienced doctor performs the osteotomy operation.
Currently, no device for a surgeon to perform a specific bone operation is used for preoperative practice, and therefore, only the operational experience of osteotomy can be accumulated from the surgical practice for the surgeon who needs to learn and prepare for periacetabular osteotomy.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an acetabular bone cutting operation exercise device to reduce or avoid the aforementioned problem.
In order to solve the technical problem, the utility model provides an acetabular bone cutting operation exercise device, it is used for fixed 3D to print the pelvis model that forms, it includes a bottom plate, with bottom plate fixed connection be used for fixing two stands of pelvis model cup joint two under the flexibility on the stand, with the cushion can be dismantled down and be used for the centre gripping of connection the flexible last cushion of pelvis model.

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 like parts are given like reference numerals.
Fig. 3 is a schematic structural diagram of an acetabular osteotomy manipulation exercise device according to an embodiment of the present invention; FIG. 4 is a schematic structural diagram of the pelvic model used in FIG. 3; referring to fig. 3 and 4, the utility model provides an acetabular osteotomy operation exercise device, it is used for fixed 3D to print the pelvis model 2 that forms, it includes a bottom plate 3, with 3 fixed connection of bottom plate be used for fixing two stands 4 of pelvis model 2 cup joint two flexible lower cushion 5 on the stand 4, with lower cushion 5 can dismantle the flexible upper cushion 6 that is used for the centre gripping of connection pelvis model 2.
The upper cushion block 6 and the lower cushion block 5 shown by dotted lines in fig. 3 may be made of a flexible material such as silicone through injection molding, which is used to simulate the muscle tissue of a patient and wrap the pelvis model 2, so that a training doctor can control the hand feeling,
the base plate 3 can be made of a steel plate with a thickness of 5-8mm, so that the weight of the base can be provided, and excessive displacement and deformation of the whole device caused by the action of the osteotomy operation in the process of practice are avoided.
Referring to fig. 4, the pelvis model 2 is provided with two fixing holes 21, and the upright 4 is provided with a connecting hole, so that the pelvis model 2 and the upright 4 can be fixedly connected through bolts. The position of the fixing holes 21 can be arranged at the position of the far iliac end of the pelvis model 2 and the position close to the pubic symphysis, so that the interference of the osteotomy operation part can be avoided. The fixing hole 21 may be formed by drilling after the 3D printing is completed, or may be formed by synchronous printing during the 3D printing.
When a surgeon needs to practice the osteotomy around the acetabulum, the 3D printing technology can be firstly adopted to manufacture the pelvis model 2 shown in fig. 4, then the pelvis model 2 is placed on the lower cushion block 5 and is fixed with the upright post 4 through a bolt (not shown in the figure), then the upper cushion block 6 is fixed with the lower cushion block 5 through a bolt (not shown in the figure), so that the pelvis model 2 is wrapped,
