Osteotomy guider and osteotomy surgical instrument

Abstract

The invention provides an osteotomy guider and an osteotomy surgical instrument. Wherein the osteotomy guide module comprises a first osteotomy guide block and a second osteotomy guide block, the first osteotomy guide block and the second osteotomy guide block are fixed on an osteotomy to-be-cut at an interval, the interval comprises a first gap, a second gap and a third gap which are sequentiallyconnected, and the first gap and the third gap are positioned on two sides of a straight line where the second gap is positioned. The osteotomy guider and the osteotomy surgical instrument have the advantages of good rotation resistance and medullary cavity concentricity; the osteotomy guide and osteotomy length measurement can be realized, so that the flatness of an osteotomy surface is guaranteed, the two ends of the osteotomy to-be-cut are in stable contact, the effective conduction of force is facilitated, osteoporosis is reduced, the skeletal development is promoted, bones can be healedas soon as possible, a postoperative patient can walk as soon as possible, and the early load of the patient is realized.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to an osteotomy guide and an osteotomy surgical instrument. Background technique [0002] At present, congenital dysplasia of the hip (developmental dysplasia of the hip) refers to the loss of normal position of the femoral head and hip joint, including hip dislocation, subluxation and acetabular dysplasia, unequal length of lower limbs, and limping gait; through Surgery can treat this symptom, perform osteotomy correction on the femur, and realize the reset of the affected limb. In the prior art, femoral shortening osteotomy is used, that is, the patient lies on the hospital bed, the affected limb is fixed, and the posterior approach is adopted. Surgical operations can increase the exposed area, but there are two problems: (1) When the osteotomy is completed and the reduction is performed, the distal and proximal femurs are prone to rotation, the medullary cavity at the j...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an osteotomy guide and an osteotomy surgical instrument to solve the problem of treating congenital hip joint dysplasia in the prior art, which needs to rely on the doctor's surgical experience to perform the osteotomy. bone, and the optimal osteotomy angle and position will be lost due to the movement of the patient during the operation
