Description
Technical field
This utility model is related to a kind of hip replacement osteotomy guider, and in particular to a kind of to be based on computer-aided design
The hip replacement osteotomy guider of 3D printing.
Background technology
Fracture of femoral neck is one of clinically common fracture, wherein about 80% is the fracture of displacement.With surgical technic
Development and internal fixation material improvement, prior art achieves certain progress, but its in terms of the treatment of fracture of femoral neck
Nonunion rate and femur head necrosiss rate are still higher, respectively 10% and 30% or so；On the other hand, although hip replacement
Art provides another selection for the treatment of fracture of femoral neck, but closes in internal fixation, replacement of total hip and half hip
The scheme of specifically chosen upper one quantization of shortage of section replacement, the selection of modus operandi are more affected by patient's subjective factorss
Impact, up to the present therefore there is difficult point in fracture of femoral neck.
In existing artificial hip joint replacing operation, the osteotomy of neck of femur fully relies on the range estimation and Jing for implementing operative doctor
Test, operate the cutting position and space angle of bone-cutting saw.Jing is often because doctor operates misalignment so that artificial femur neck position and
There is deviation in angle, it is impossible to effectively coordinate with artificial thigh bone, artificial hip joint dislocation occurs, causes operative failure.
Foreign countries also have using infrared rays navigation system at present, but the problem for existing is：(1), many places are attacked into the human body
Osseous tissue does and indicates, not only especially increased iatrogenic injury, and may cause infection suppurates, causes the failure performed the operation；
(2) it is cumbersome when, using to waste time and energy, typically will 15-30 minutes operating；(3), equipment cost rather expensive；
(4), operating technology requires skillfully to need Special Training；(5), in operating process, blind spot is more, and position is restricted；(6) it is, infrared
The equipment of line navigation system is separated with human body, and human body is very unstable, as long as the body of patient occurs point change, infrared rays navigation system
The accuracy of system fails immediately.
Based on the current situation of above-mentioned prior art, there is presently no one kind precisely can implement hip replacement surgery,
Reduce operation risk, shorten the guiding or positioner of operating time.

In above-mentioned technical proposal, the front end surface of the guider body is provided with for placing the extension of goose saw.
In above-mentioned technical proposal, the guider body is integrally formed by 3D printing.
The hip replacement osteotomy guider based on computer-aided design 3D printing in this utility model, by using
Plant fiber's such as corn fiber is integrally formed using 3D printing technique as raw material, is carried out for the anatomical data of patient
Bodyization is accurately customized, and using the front end surface of guider body, implements accurate osteotomy to neck of femur, controls the side of goose saw in art
To, angle, height, implement in art and formed with Design identical for patient specific anatomic's data osteotomy surface, from
And precise control operation precision.Accurately osteotomy surface is provided for preferable artificial full-hip joint femoral prosthesiss position in vivo,
The angle of goose saw inclined plane, direction, position are fixed into accurate, most of work of operation is placed on into Preoperative Method, handss are shortened
The time that art is implemented, the degree of accuracy of operation is improve, operation risk is reduced.
