Description
Technical field
The present invention relates to medicine technology field, more particularly to a kind of 3D printing astragalus prosthese.
Background technology
Astragalus is the hinge for connecting lower limb and foot, bears weight transfer and is coupled with what is moved, is the important function of foot
Unit.Astragalus is located in ankle cave, and respectively with distal tibial articular surface, articular surface and navicular bon e formation pollex are closed before, during and after calcaneum
(ankle-joint), subtalar joint and articulatio talonavicularis are saved, surrounding ligaments attachment is numerous, and profile is irregular, and anatomical structure is relative complex.Its
Region of the surface about more than 2/3 is covered by articular cartilage, and blood supply mostlys come from inner side deltoid ligament, capsular ligament, instep
Capsular ligament in front of the ankle-joint of bone sinus, outside talocalcanean ligaments and neck body intersection.The astragalus ischemic caused by the reasons such as wound
The patient of necrosis, such most patients fall ill to be unilateral, and ankle-joint pain, swelling and medical history are longer, severe patient's difficulty in walking, need
Performed the operation.
Current procedure mode mainly has three kinds, and the first is joint fusion, and its advantage is that symptom improves substantially, operation behaviour
Make it is relatively easy, it is curative for effect, be current standard procedures, but shortcoming is equally obvious, post-operative recovery time length, have and be not cured necessarily
Conjunction rate, joint motion is lost, bilateral patient has a great influence to life, and the secondary regression of periarticular is accelerated；Second is that marrow core subtracts
Art is pressed, its advantage is that operation is simple, and risk is low, and shortcoming is that indication is limited, efficient relatively low；The third is full ankle-joint displacement
Art, it is to retain function of joint the advantages of currently used ankle prosthesis, mitigates pain, but shortcoming is that indication is very narrow, operation behaviour
Make complexity, risk is high, and costly, prosthese service life is limited.
Ankle prosthesis of the prior art is made up of multiple parts mostly, and main function is by the articular surface of talus necrosis
Replace, astragalus major part is retained, thus design half ankle-joint using assembly type or full ankle-joint, but its is main
It is complicated, perishable, and can not with bon e formation it is good grow into effect, short life.
The content of the invention
Based on this, it is necessary to for ankle prosthesis in the prior art it is complicated, perishable, grow into effect it is undesirable with
A kind of and the problem of short life, there is provided 3D printing astragalus prosthese.
To solve the above problems, the present invention takes following technical scheme：
A kind of 3D printing astragalus prosthese, including integrally connected head of talus, neck of talus and body of talus, the head of talus, institute
It is material through 3D printing integrated molding that neck of talus and the body of talus, which are stated, using vitallium,
The head of talus includes the articulatio talonavicularis face one forward,
The axis of the neck of talus has 15 °~20 ° of introversion,
The body of talus includes：The trochlea of talus articular surface of top, anterior calcanean articular surface, facies articulares calcanea media and the heel of lower section
Articular surface, and the articular facet of medial malleolus of inner side and the articular facet of lateral malleolus in outside.
The present invention is using 3D printing technique printing astragalus prosthese, and head of talus, neck of talus and body of talus are through 3D printing integration
Shaping, service life are grown, without renewal part after implantation within a patient；The material of 3D printing astragalus prosthese is vitallium,
Immunological rejection is not produced with human body；Counted through big data and combine biomethanics to be designed, retained to greatest extent
The function of joint of patient.

In one of the embodiments, as shown in figures 1 to 6, a kind of 3D printing astragalus prosthese is present embodiments provided, including
Integrally connected head of talus, neck of talus and body of talus, head of talus, neck of talus and body of talus are beaten using vitallium as material through 3D
Integrated molding is printed, head of talus includes the articulatio talonavicularis face one forward, and the axis of neck of talus has 15 °~20 ° of introversion, astragalus
Body includes：The trochlea of talus articular surface of top, anterior calcanean articular surface, facies articulares calcanea media and the facies articularis calcanea posterior of lower section, and inner side
Articular facet of medial malleolus and outside articular facet of lateral malleolus.
The 3D printing astragalus prosthese that the present embodiment provides is to carry out CT scan to normal person's ankle and foot, and astragalus data are being counted
Three-dimensional reconstruction is carried out on calculation machine, after a series of smooth smooth-going processing, is formed with the printing of cobalt chrome molybdenum (CoCrMo) alloy, astragalus
Head, neck of talus and body of talus are grown through 3D printing integrated molding, service life, without renewal part after implantation within a patient；3D
The material for printing astragalus prosthese is vitallium, and immunological rejection is not produced with human body；Counted through big data and combine life
Material resources are designed, and remain the function of joint of patient to greatest extent.Meanwhile the 3D printing that is proposed of the present embodiment away from
Bone prosthese has the following technical effect that：
(1) solve the problems, such as that the expectant treatment time is long and uncertain therapeutic efficacy is cut；
(2) solve ankle fusion post-operative recovery time length, the phenomenon that disunion be present, reduce range of motion,
The problem of periarticular regression is accelerated；
(3) it is small to solve marrow internal decompression accommodation, it is efficient relatively low the problem of；
(4) it is narrow to solve total ankle joint replacement accommodation, operation is complicated, and risk is high, costly, prosthese restricted lifetime
The problem of；
(5) the 3D printing astragalus prosthese in this implementation can effectively treat pain caused by diaz disease and activity
It is limited.
As a kind of specific embodiment, 3D printing astragalus prosthese is divided into two groups of men and women, and every group of 3D printing astragalus is false
The scope and length of the ratio between the length of body and the scope of the ratio between width, width and height are respectively with scope the ratio between highly：
