The multi-disciplinary cross-application such as machine Computer Aided Design and auxiliary manufacture.In recent years, with China's 3D printing technique and digital medical
The progress of technology, 3D printing technique are combined with the substance that clinical medicine is applied and are gradually started to walk.Based on 3D printing technique for trouble
The digitlization surgical navigational template of person's personalized designs has been widely used the essence of the operations such as orthopaedics, plastic surgery, oral cavity
In trueization, the operation of precision not only increases surgical quality, but also can reduce unnecessary wound, realizes minimally invasive.
As shown in Figures 2 to 11, in a preferred embodiment, the quantity of guide post 2 is multiple, and each guide post 2 is equipped with
The quantity of one sliding rail 21, the sliding slot 11 in guide sleeve 1 is consistent with the quantity of sliding rail 21 and sets with the one-to-one correspondence of sliding rail 21
It sets.With no restriction to the quantity of guide post 2, the quantity of guide post 2 is three to the utility model in the present embodiment, respectively first
Guide post 2a, the second guide post 2b and third guide post 2c.Sliding rail 21 on first guide post 2a is the first sliding rail 21a, second
Sliding rail 21 on guide post 2b is the second sliding rail 21b, and the sliding rail 21 on third guide post 2c is third sliding rail 21c.Guide sleeve 1
Sliding slot 11, respectively first sliding groove, second sliding slot and third sliding slot there are three being opened up on inner wall, wherein first sliding groove and first
Sliding rail 21a is correspondingly arranged, and second sliding slot is correspondingly arranged with the second sliding rail 21b, and third sliding slot is correspondingly arranged with third sliding rail 21c.
Specifically, the collapse of femoral head prosthetic device 100 of the present embodiment in use, can first be inserted into the first guide post
The first sliding rail 21a on 2a, the first guide post 2a can be slided along first sliding groove, adjusted the first guide post 2a according to preoperative planning and stretched
Enter the depth in femoral head 200, make it that certain position for collapsing region of femoral head 200 be jacked up certain altitude by desired trajectory,
Then the first guide post 2a is extracted.Then, the second guide post 2b is inserted into and adjusted in the same fashion, makes it will by desired trajectory
After the other positions for collapsing region of femoral head 200 jack up certain altitude, the second guide post 2b is extracted.Followed by by identical
Third guide post 2c is inserted into and is adjusted to mode, and whole regions that collapses is pushed to return to normal position.It should be noted that this reality
Example is applied to the first guide post 2a, the second guide post 2b and third guide post 2c using sequentially with no restriction.
Referring again to Fig. 2, in a preferred embodiment, the guide direction of guide post 2 is configured by preoperative planning, and
Different guide posts 2 can repair the different location for collapsing region.In order to make collapsing for the corresponding jack-up of adjacent guide post 2
Sunken region can partially overlap, and the angle between the direction of insertion bracket of any two guide post 2 is at an acute angle, in this way can be with
The gap collapsed between the position in region for avoiding the angle between two guide posts 2 excessive and causing respectively to jack up is excessive, from
And it is conducive to collapsing femoral head 200 region gradually and be comprehensively pushed to return to normal position.However, in other examples,
The guide direction of more guide posts 2 can all be parallel to each other, to adapt to the different collapse of femoral head situations of different patients.
As shown in Fig. 6, Fig. 9 to Figure 11, further, in a more preferred embodiment, sliding rail 21 is outside guide post 2
Strip bulge on circumferential surface, sliding slot 11 be with the matched strip groove of sliding rail 21, have the advantages that be easy to make.It is understood that
, sliding rail 21 can be abnormity protrusion, for example, the cross section of sliding rail 21 can also be able to be in class in the shape of similar " ten " word
Like the shape of " convex " word.The first sliding rail 21a, the second sliding rail 21b of the present embodiment and the shape of third sliding rail 21c can be item
Shape protrusion is special-shaped protrusion, or a part be strip bulge and another part is that abnormity is raised, can be according to practical need
Want flexible setting.The shape of sliding slot 11 and corresponding 21 shape adaptation of sliding rail.
In the above-described embodiments, the extending direction of sliding rail 21 is consistent with the length extending direction of guide post 2, is conducive to guide post
2 extend along a length thereof direction sliding, convenient for adjusting.Further, in a preferred embodiment, guide post 2 is equipped with graduation mark,
Graduation mark is for identifying the depth that guide post 2 protrudes into femoral head 200, and according to preoperative planning, the guide post 2 of the present embodiment is protruded into
Depth in femoral head 200 is the height for collapsing region and needing to be jacked up of femoral head 200.The setting of graduation mark facilitates medical care
Personnel observe in real time during adjusting guide post 2, and that grasps femoral head 200 collapses the case where region is jacked up, Jin Erti
High surgical quality.It should be understood that the unit of the graduation mark in the present embodiment in each guide post 2 is millimeter, graduation mark is corresponding with
Scale value.
In a further embodiment, it is carved with first identifier symbol in the position for sliding slot 11 being corresponded on the outer surface of guide sleeve 1.It can
With understanding, the guide sleeve 1 of the present embodiment can be irregular shape, be inserted into the first guide post 2a, the second guide post 2b and
Before third guide post 2c, need to recognize therefore the position of respectively insertion guide sleeve 1 corresponds to sliding slot in the outer surface of guide sleeve 1
First identifier symbol is carved in 11 position, facilitates the position for recognizing that each guide post 2 is inserted into guide sleeve 1, conducive to the progress of operation.Into one
The guide post 2 on step ground, the present embodiment is equipped with operation handle 22, and medical staff is facilitated to operate, and is carved in operation handle 22 and first
The corresponding second identifier symbol of identifier, facilitates medical staff to recognize.For example, in the present embodiment on the outer surface of guide sleeve 1
It is carved with the first identifier symbol of digital " 1 ", second identifier symbol corresponding with the first identifier symbol in the position of corresponding first sliding groove
Number for " guiding 1 ", it is engraved in the operation handle 22 of the first guide post 2a；The position of second sliding slot is corresponded on the outer surface of guide sleeve 1
