Be equipped with sliding axle in vivo, sliding axle is equipped with fixation hole, implantable cushion block by the cushion block on metacarpal bone prosthese be implanted into mouth implantation and with
Fixation hole is fixedly connected, to extend the length of metacarpal bone prosthese.
Further, which is equipped with multiple fixation holes, for the slidable adjustment by sliding axle and is adapted to difference
The implantable cushion block of growth and development situation connects.
Further, the fixation hole spaced set on sliding axle.
Further, implantable cushion block is equipped with the connecting hole being adapted with fixation hole.
Further, implantable cushion block is connected by lock screw and sliding axle locking.
Further, the distal portions of metacarpal bone prosthese are implanted into pulp cavity by Distal transition bridge and are fixedly connected with cortex.
Further, the proximal part of metacarpal bone prosthese is implanted into pulp cavity by Proximal transition bridge and is fixedly connected with cortex.
Further, the Distal transition bridge and Proximal transition bridge are fixedly connected by screw with cortex.
Further, the fixation hole of the sliding axle is also used to pass through lock screw in the case where not being implanted into implantable cushion block
It is fixedly connected with metacarpal bone prosthese.
According to the above aspect of the present invention, implantable cushion block and false intracorporal sliding axle are connected by children's property metacarpal bone implantable prosthese
Connect, achieved the purpose that extend prosthesis length, avoid because repeatedly customization replacement prosthese bring damage, save economy at
This.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Joining shown in Fig. 1, Fig. 1 is the structural schematic diagram of children's property metacarpal bone implantable prosthese of the present invention, and in figure, 40 be metacarpal bone,
10 be metacarpal bone prosthese.
Join shown in Fig. 2 to Fig. 4, present embodiments provides a kind of children's property metacarpal bone implantable prosthese, including metacarpal bone prosthese 10
And implantable cushion block 20, metacarpal bone prosthese 10 is interior to be equipped with sliding axle 30, and sliding axle 30 is equipped with fixation hole 31, and implantable cushion block 20 passes through
Cushion block implantation mouth 11 on metacarpal bone prosthese 10 is implanted into and is fixedly connected with fixation hole 31, to extend the length of metacarpal bone prosthese 10.
In the present embodiment, the sliding axle 30 is equipped with multiple fixation holes, for the slidable adjustment by sliding axle and fits
It should be connected in the implantable cushion block 20 of different growth and development situations.
In the present embodiment, 31 spaced set of fixation hole on sliding axle 30.
In the present embodiment, implantable cushion block 20 is equipped with the connecting hole 21 being adapted with fixation hole.
In the present embodiment, implantable cushion block 20 is connected by lock screw 22 and the locking of sliding axle 30, firm stable.
In the present embodiment, the distal portions of metacarpal bone prosthese 10 are implanted into pulp cavity by Distal transition bridge 12 and are consolidated with cortex
Fixed connection is keeping good stability simultaneously, is mitigating surrounding soft tissue's excitation to obtain more stable fixed effect.
In the present embodiment, the proximal part of metacarpal bone prosthese 10 is implanted into pulp cavity by Proximal transition bridge 13 and is consolidated with cortex
Fixed connection is keeping good stability simultaneously, is mitigating surrounding soft tissue's excitation to obtain more stable fixed effect.
In the present embodiment, the Distal transition bridge 12 and Proximal transition bridge 13 are fixedly connected by screw 14 with cortex.
In the present embodiment, the fixation hole 31 of the sliding axle is also used to pass through in the case where not being implanted into implantable cushion block 20
Lock screw 22 is fixedly connected (shown in ginseng Fig. 3) with metacarpal bone prosthese 10.
It is implanted into the case of the present embodiment prosthese below by different patients, further illustrates technical effect of the invention:
Case 1
Children's harvester twists wound and causes metacarpal bone missing, need to print metacarpal bone prosthese by " image method ", consider that patient age is smaller,
Other each metacarpal bones are in growth and development, until length will increase before growth and development terminates, the simple prosthese that prints needs often
Year printing brings tremendous economic to bear, is used by the prosthese for patient, except initial surgery is conventional prosthetic implant surgery, with
Patient can be implanted by small notch cushion block achieve the purpose that extend prosthesis length every year afterwards, meet normal appearance and function need
It asks.
Case 2
Certain child patient is because Langerhans cell increase disease causes metacarpal bone to destroy in a short time, and row chemotherapy is controlled after operation window strikes off
It treats, but pathologic fracture occurs in original metacarpal bone strength failure, epiphysis destroys, and growth and development terminates.It is used by the prosthese, it can be big
The thorough tumor resection part of section, provides the support of sufficient intensity after implantation for metacarpal bone, and initial surgery is conventional prosthetic implant surgery,
Later patient meets normal appearance and function need per that can achieve the purpose that extension prosthesis length by the implantation of small notch cushion block every year
It asks.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
