X-ray is coordinated osteotomy determining corrective surgery scheme using traditional osteotomy plate in art with nail before by checking operation in patients
Tabulare is followed closely to the position for needing operation, and operation is completed through osteotomy plate finally by osteotomy instrument.In operation, only rely on doctor's
Osteotomy plate is attached to treat that operative site can cause positioning inaccurate by experience, and then causes excessive osteotomy or osteotomy is inadequate asks
Topic.Also, the osteotomy Ban Shiyou world large-sized artificial joint company used in art is according to the specific several models of American-European ethnic group
Prosthese is designed production, it is impossible to match completely with patient illness part, so will also result in doctor's art excessive osteotomy or
The inadequate problem of osteotomy.Additionally, when performing the operation to the complicated state of an illness, being positioned using traditional osteotomy plate, can also extend hand
The art time, increase the risk of patient's infection.
Therefore, it is necessory to provide a kind of individuation osteotomy guide plate, to overcome defect present in prior art.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, the individuation osteotomy guide plate of accurate positioning.
For achieving the above object, individuation osteotomy guide plate of the present utility model is achieved through the following technical solutions：A kind of
Body osteotomy guide plate, is mounted on femur, that it includes being made into integration by 3D printing technique and fit with femur corresponding site
Main body and the locating dowel of setting is protruded out upwards by main body, the main body has " T " shape setting osteotomy groove.
Preferably, the osteotomy groove includes the first slit arranged through main body in horizontal direction and passes through in vertical direction
The second slit of main body setting is worn, first slit connects setting with the second slit.
Preferably, also have in lateral through the multiple through holes for arranging in the main body.
Preferably, the through hole connects setting with second slit.
Preferably, the main body includes the protuberance and the carrier positioned at protuberance side of " T " shape setting, described
Osteotomy groove is on protuberance, and the locating dowel is interruption-like on carrier.
Preferably, in shape is extended transversely through on the protuberance, second slit is in vertically to pass through to first slit
Shape is worn on the protuberance, the through hole is in lateral penetration state on the protuberance.
Preferably, the locating dowel has to run through the location hole of setting and run through in circumferential direction in axial direction and arranges
Multiple grooves.
Preferably, the locating dowel is conical in main body.
Preferably, the main body has the binding face fitted with femur corresponding site.
Individuation osteotomy guide plate of the present utility model is fitted by the binding face of main body with femur corresponding site, and by setting
Location hole in locating dowel coordinates to be mounted on femur with Kirschner wire, and passes through "T"-shaped osteotomy by osteotomy instrument
, to realize osteotomy, simple structure is easy to operate, accurate positioning for groove, and individuation osteotomy guide plate is corresponding according to patient femur
Station diagram is made as design data and by 3D printing technique, it is to avoid lead because of osteotomy guide plate with femur corresponding site mismatch
Cause excessive osteotomy or osteotomy inadequate.

Specific embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.
Please join shown in Fig. 1 to Fig. 4, individuation osteotomy guide plate 100 of the present utility model is mounted on femur 200 to be used to guide
Osteotomy instrument osteotomy, it includes the main body 1 fitted with the corresponding site of femur 200 and protrudes out the positioning of setting upwards by main body 1
Post 2.The main body 1 is that the threedimensional model reconstructed according to the medical image of femur 200 is designed and by 3D printing technique one
Made by body, it has the binding face 10 fitted completely with the surface of the corresponding site of femur 200.
The main body 1 includes the protuberance 11 and the carrier 12 positioned at the side of protuberance 11 of " T " shape setting.It is described
Protuberance 11 has " T " shape through the osteotomy groove 13 for arranging and multiple in the lateral through hole 14 through setting.The osteotomy
Groove 13 is used to that osteotomy instrument osteotomy to be passed through and guided for osteotomy instrument, and it includes narrow in extend transversely through the setting of protuberance 11 first
Groove 130 runs through the second slit 131 that protuberance 11 is arranged with vertical.First slit 130 is in connect with the second slit 131
