Description
Technical field
The present invention relates to a kind of floated navigation module of 3D printing, belong to clinical medicine Orthopeadic Surgery technical field.
Background technology
Methods for Distal Femoral Fractures is often because fracture end is crushed, fracture line involves articular surface, and internal fixation operation mechanical property requirements are high,
It is current orthopaedic trauma operative treatment difficult point.Internal fixation operation is required to cut the anatomical reduction for carrying out looking at lower sclerite straight, reached
Articular surface is smooth, stable interior fixation, and the healing of its articular surface fracture requires between fracture end without absorbing, small by bone without poroma
Beam adhesion, i.e. I phases are healed, and are easy to early ambulant and early stage to carry out reconditioning, to prevent later stage deformity of knee to heal,
The complication such as infection, stiff, osteoarthritis after traumatic and bone nonunion occur.
Whether position that traditional orthopaedics internal fixation operation is placed in bone plate, all directions screw are touched or are broken into articular cavity
And whether comprehensive fix in terms of sclerite faces many problems, often make clinician is multiple in art to put tune
Try the position of hone lamella, multiple fluoroscopic observation screw angle, direction and length it is whether optimal, repeat to put nail and cause the broken of sclerotin
Bad, extensive soft tissue is cut and periosteum stripping, operating time extension and fracture fixation built on the sand etc., influence surgical effect.Cause
This, good preoperative planning is particularly important.
The appearance of digital orthopaedics, preoperative clinician can on PC by relevant medical software to each single
Sclerite is shifted recovers its anatomical structure with virtual reset, can be to bone plate implantation site and spiral shell with model after reset
The design that nail placing direction and length are optimized, determines the personalized operation plan of intra-articular fracture.But how by numeral
Accurate reproduce of preoperative programme for changing design is a problem, and the 3D printing technique then risen is digitizing technique conversion
The combination of a bridge block digitizing technique and 3D printing technique is erected to clinical practice, for fixed solution in optimizing
Implementation provide may.Internal fixation screw direction and length are determined using Design of digital, and under 3D printing technique auxiliary
Implement, it is no longer necessary to prepare that a large amount of apparatuses are standby, eliminate time of measuring and the laborious steps repeatedly having an X-rayed in art, save significantly
About operating time, reduces intraoperative blood loss and anesthesia duration, reduces operating difficulty, greatly improves success rate of operation.Most
The biomechanical property of interior fixation is improved afterwards, expected surgical effect is reached, so as to promote patient's faster rehabilitation
Fixed solution in the accurate ideal for implementing Design of digital of 3D printing navigation module auxiliary, is practicable one kind side
Method.Navigation module includes a connected substrate（Card plane）With more than three supporting pillars with hollow screw way.This seminar is
Take the lead in designing whole substrate with the 3D printing navigation module with screw way of the complete screens in bone face the applications well in clinical operation.Root
According to the limited local bone face anatomical structure appeared of operative site, substrate, design are used as by the use of the reverse modulus of medical software Mimics
The default screw way at the accurate implantation surgery position of guiding Kirschner wire in module with navigation screw way, art.Pull out navigation module, bone plate
Corresponding nail, which is inserted in Kirschner wire, can make bone plate be in default bone plate placement location, and then smoothly complete bone plate, screw
Interior fixation, whole integration step objectively ensure that virtual design scheme accurate reproduction in reality, realize it is disposable into
Work(is inserted.
Prior art has the following disadvantages：（1）3D printing technique auxiliary limbs fracture operation, it is many using the overall fracture of printing
Model entity is supplied in art with reference to comparing, and is not designed and is printed the implementation of navigation module assisted surgery.（2）Previously research takes the lead in designing
3D printing navigation module auxiliary in fixed implementation, it usually needs module substrate want soft tissue on the bone face of screens and
Periosteum is thoroughly peeled off, and promotes navigation module cmpletely screens, it is to avoid the drift of navigation module, improves the precision for putting nail.
And healing of the further stripping of soft tissue and periosteum to comminuted fracture is still likely to result in different degrees of negative effect.
The content of the invention
It is an object of the invention to provide a kind of floated navigation module of 3D printing, for original 3D printing navigation mould
Block is improved, using knee joint substantially exposure peelable bone mark design card plane, will put nail scope suspend, it is less or
Periosteum and soft tissue, which need not be peeled off, can put nail.
To achieve these goals, technical scheme is as follows.
A kind of floated navigation module of 3D printing, specific preparation process is as follows：
（1）Progress continuous thin layer CT scan preoperative to Methods for Distal Femoral Fractures patient, the Dicom formatted files after CT scan are inputted
