Description
Technical field
The present invention relates to orthopedic medical device technical field, specifically, being before a kind of personalized type femoral bone end prosthesis is implanted into
Inclination angle guider.
Background technology
Type femoral bone end prosthesis is a part for hip joint artificial prosthesis, is to be used in artificial hip joint replacing operation, with weight
The anatomical structure of human hip is built, and it is made to obtain normal mechanical property and restores or completes certain physiological function, thus
Achieve the purpose that relieve pain, improve function and quality of life.Artificial hip joint is made of components such as femoral stem and femorals head,
Wherein femoral stem plays the role of fixing and supporting as human femur under loading and the connecting component of human body distal end is connected in human body,
Placement location is directly related to the therapeutic effect of hip replacement surgery.
The angle that type femoral bone end prosthesis is placed determines whether anteversion of femoral neck can restore normal, if placing forward leaning angle
It is excessive, then easy anterior dislocation, conversely, then easy backward dislocation.Inaccurate femoral prosthesis, which leans forward, is unfavorable for post-operative recovery.In order to
Type femoral bone end prosthesis is placed in suitable angle, firstly, it is necessary to which neck of femur carries out osteotomy operation, the step is (a kind of a by patent
Property type femoral bone end prosthesis implantation guider application number:201621206362.7) realize.Secondly, it needs before being carried out to prosthesis handle
Degree of tilt adjusts, however, in the prior art, is had the following disadvantages about top rake adjustment and defect.
The technological means that top rake is taken in the prior art is:It is planned by doctor by preoperative two dimension, manually according to warp in art
Operation is tested, using bone anatomical structure as reference, error is larger, and forward leaning angle is caused to restore undesirable.Its error is mainly reflected in
Following aspect:1. forward leaning angle adjustment is inaccurate;2. prosthese and the adjustment of femoral shaft angle are inaccurate.Also the way having is based on light
The device of navigation is learned, somewhat expensive, assembling is complicated, inconvenient for use or universal models the adjusting apparatus of leaning forward, and is not personalized
Setting, precision are inadequate.
Chinese patent literature:CN201420854393.8, the applying date:2014.12.29, patent name is:Femoral stem is false
Body.A kind of type femoral bone end prosthesis is disclosed, it is remote which includes integrally formed neck of femur, femur handle proximal end and femoral stem
End, the cross section of neck of femur are ellipse, and the cross section of femoral stem distal end is rectangle, and the cross section on the inside of femur handle proximal end is circle
Slip circle shape, the cross section of femoral stem proximal lateral are formed with the rectangular of chamfering for both sides.
A kind of type femoral bone end prosthesis of above patent document makes hip joint scope of activities big, and Using prosthesis is stable, facilitating operation,
Abrasion is reduced, there is good Bone Ingrowth and the good blood fortune of femoral bone cavitas medullaris is kept to extend the prosthese service life.But about a kind of needle
To bone personalized designs, angle can be accurately determined in art, with patent (it is a kind of personalization type femoral bone end prosthesis implantation guider,
Application number:201621206362.7) a kind of personalized type femoral bone end prosthesis being used in combination is implanted into top rake guider at present then
There is no relevant report.
In conclusion there is an urgent need for one kind to be directed to bone personalized designs, angle can be accurately determined in art, it is (a kind of a with patent
Property type femoral bone end prosthesis implantation guider, application number:201621206362.7) a kind of personalized femoral stem for being used in combination is false
Body is implanted into top rake guider.
Invention content
The purpose of the present invention is being directed to deficiency of the prior art, a kind of for bone personalized designs, energy in art is provided
Accurately determining angle, with patent (a kind of personalization type femoral bone end prosthesis implantation guider, application number:201621206362.7) connection
Close a kind of personalized type femoral bone end prosthesis implantation top rake guider used.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of personalization type femoral bone end prosthesis implantation top rake guider, which is characterized in that the guider includes patch
Bone plate and guide plate;The patch bone plate and guide plate are Integratively formed;The shape of the patch bone plate is with reference to therewith
The outer surface of the femur of fitting designs;The patch bone plate is curved-surface structure;The curved surface and near end of thighbone of the patch bone plate
Outer surface matches;The guide surface is bonded with osteotomy surface;The guide surface matches with the prosthese side of preoperative setting;Institute
The guide plate stated is bonded to form placing groove with osteotomy surface.
As a kind of perferred technical scheme, the guide plate matches with prosthese side.
As a kind of perferred technical scheme, the patch bone plate and guide plate are made of titanium alloy material.
The invention has the advantages that:
1st, a kind of personalized type femoral bone end prosthesis implantation top rake guider, is designed by personalized bone, can essence in art
It determines position, determines that prosthese placement forward leaning angle is accurate, the relationship of guide surface and prosthese is clear and definite, in artificial hip joint replacing operation
Using being with a wide range of applications;
2nd, by accurate preoperative planning, Design assistant surgical instrument reaches the effect for accurately placing top rake in art according to plan
Fruit improves anteversion of femoral neck degree and restores precision;
3rd, by preoperative three-dimensional planning, according to prosthese spatial position, guide surface is determined;Using can be sudden and violent near end of thighbone art
The bone face of dew, design patch bone conduction plate, meet prosthese lean forward guiding requirement;
4th, using prosthese side, corresponding guide surface is generated, guide surface chooses best guide angle according to preoperative three-dimensional planning
Degree;
5th, in surgical procedure, directly implement operation by guide surface, convenient for disposably finding top rake orientation accurately, be oriented to
Face protrudes from guider body lateral surface and accurate top rake, surgical procedure is found in patient's surgical procedure convenient for operating doctor
