An osteotomy guide for treating congenital hip dysplasia

Abstract

An osteotomy guide for treating congenital hip dysplasia comprises: an osteotomy guide body; an osteotomy groove, a Kirschner wire hole and a scale mark are arranged on the upper surface of the osteotomy guide body; the osteotomy groove comprises: a transverse osteotomy groove and a longitudinal osteotomy groove; the transverse osteotomy groove is parallel to the upper edge of the osteotomy guide body and parallel to each other; the longitudinal osteotomy groove is vertically connected to the transverse osteotomy groove; an arc-shaped groove is arranged on the lower surface of the osteotomy guide body; a scale mark is arranged next to the osteotomy groove; and the osteotomy groove and the Kirschner wire hole are both hollowed out. The advantages of the utility model are: it can realize transverse osteotomy of the femur, and can complete the more difficult Z-shaped osteotomy, and at the same time can effectively avoid the situation where the osteotomy surfaces at both ends of the femur are uneven. At the same time, because the lower surface has an arc-shaped groove that fits the surface of the femur, it plays a certain limiting role, and the fixation of the Kirschner wire makes the fixation of the osteotomy guide more stable, which can reduce the risk of surgery and reduce the time of surgery.

Description

Technical Field

[0001] The utility model belongs to the technical field of osteotomy medical instruments, in particular to an osteotomy guide plate for treating congenital hip dysplasia. Background Art

[0002] At present, the treatment of congenital hip dysplasia requires transverse osteotomy of the femur to remove part of the bone, and the total length of the femur becomes shorter after the operation. This operation is performed by the doctor's bare hands, relying on subjective judgment of whether the osteotomy surface is parallel. It is possible that the two ends are not level, resulting in poor alignment, delayed healing or non-healing of the fracture in the later stage, and the upgraded version of transverse osteotomy, Z-type osteotomy, is more difficult and risky. Summary of the invention

[0003] The technical problem to be solved by the utility model is to design an osteotomy guide plate for treating congenital hip dysplasia, which can realize transverse osteotomy of the femur and can complete the more difficult Z-shaped osteotomy, while effectively avoiding the uneven osteotomy surfaces at both ends of the femur, reducing surgical risks and shortening surgical time.

[0004] The utility model is achieved in this way:

[0005] An osteotomy guide plate for treating congenital hip dysplasia, comprising: an osteotomy guide plate body;

[0006] The upper surface of the osteotomy guide plate body is provided with an osteotomy groove, a Kirschner wire hole and a scale mark;

[0007] The osteotomy groove comprises: a transverse osteotomy groove and a longitudinal osteotomy groove;

[0008] The transverse osteotomy groove is parallel to the upper edge of the osteotomy guide body and parallel to each other;

[0009] The longitudinal osteotomy groove is vertically connected to the transverse osteotomy groove;

[0010] The lower surface of the osteotomy guide plate body is provided with an arc-shaped groove;

[0011] The scale mark is arranged beside the osteotomy groove;

[0012] The osteotomy groove and the Kirschner wire hole are both hollow.

[0013] Furthermore, a plurality of transverse osteotomy grooves and one longitudinal osteotomy groove are provided on the upper surface of the osteotomy guide plate body.

[0014] Furthermore, the Kirschner wire holes are located at the upper and lower ends of the upper surface of the osteotomy guide plate body, and two Kirschner wire holes are distributed at each end.

[0015] The utility model has the advantages of being able to achieve transverse osteotomy of the femur and the more difficult Z-shaped osteotomy, while being able to effectively avoid the uneven osteotomy surfaces at both ends of the femur. At the same time, since the lower surface has an arc-shaped groove that fits the surface of the femur, it plays a certain limiting role, and with the fixation of the Kirschner wire, the fixation of the osteotomy guide is relatively stable, which can reduce the risk of surgery and reduce the time spent on surgery.

[0021] like Figure 1 As shown, an osteotomy guide plate for treating congenital hip dysplasia comprises: an osteotomy guide plate body 1;

[0022] The upper surface of the osteotomy guide plate body 1 is provided with an osteotomy groove 11, a Kirschner wire hole 12 and a scale mark 13;

[0023] The osteotomy groove comprises: a transverse osteotomy groove 111 and a longitudinal osteotomy groove 112;

[0024] The transverse osteotomy groove 111 is parallel to the upper edge of the osteotomy guide body 1 and parallel to each other;

[0025] The longitudinal osteotomy groove 112 is vertically connected to the transverse osteotomy groove 111;

[0026] The lower surface of the osteotomy guide plate body 1 is provided with an arc-shaped groove 14;

[0027] The scale mark 13 is provided beside the osteotomy groove 11;

[0028] The osteotomy groove 11 and the Kirschner wire hole 12 are both hollow.

[0029] Furthermore, a plurality of transverse osteotomy grooves 111 and a longitudinal osteotomy groove 112 are provided on the upper surface of the osteotomy guide plate body 1 .

[0030] Furthermore, the Kirschner wire holes 12 are located at the upper and lower ends of the upper surface of the osteotomy guide plate body 1, and two Kirschner wire holes 12 are distributed at each end.

[0031] During transverse femoral amputation surgery, Figure 1 , Figure 2 As shown, the arc groove 14 is first fitted with the surface of the femur 2, and after adjusting to the designated surgical position, the osteotomy guide body 1 is fixed to the femur 2 using Kirschner wires through the Kirschner wire holes 12 at both ends. The cut position is determined according to the scale mark 13, and then the saw blade is passed through the osteotomy groove 11 to cut the osteotomy surface 21 and the osteotomy surface 22, separate the bone block 23, and then the wound surface of the bone block 24 and the bone block 25 are fitted and spliced ​​to complete the transverse cut operation.

[0032] During femoral Z-section surgery, Figure 1 , Figure 3 and Figure 4 As shown, the arc groove 14 is first fitted with the surface of the femur 3, and after adjusting to the designated surgical position, the osteotomy guide body 1 is fixed to the femur 3 using Kirschner wires through the pinholes 12 at both ends. The truncation position is determined according to the scale mark 13, and then the saw blade is passed through the osteotomy groove 11 to cut out the longitudinal osteotomy surface 31, the transverse osteotomy surface 32, the transverse osteotomy surface 33 and the transverse osteotomy surface 34. Bone blocks 35 and 36 are separated, and then the wound surfaces of bone blocks 37 and 38 are fitted and spliced ​​to obtain a new femur 4, that is, the Z-type truncation surgery is completed.

[0033] The utility model has the advantages of being able to achieve transverse osteotomy of the femur and the more difficult Z-shaped osteotomy, while being able to effectively avoid the uneven osteotomy surfaces at both ends of the femur. At the same time, since the lower surface has an arc-shaped groove that fits the surface of the femur, it plays a certain limiting role, and with the fixation of the Kirschner wire, the fixation of the osteotomy guide is relatively stable, which can reduce the risk of surgery and reduce the time spent on surgery.

[0034] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
