A kind of finger joint prosthesis, including：Articulations digitorum manus is leaned on including connected ball-and-socket head and articulations digitorum manus shank, articulations digitorum manus shank
The both sides at the nearly first end of ball-and-socket are provided with the first vertical muscle of protrusion；Metacarpophalangeal joints, including connected bulb and metacarpophalangeal joints shank,
Metacarpophalangeal joints shank is provided with the second vertical muscle of protrusion close to the both sides of bulb one end, and the second vertical muscle and the first vertical muscle can be embedded in disease
Suffer from vivo preventing metacarpophalangeal joints from rotating in patient with articulations digitorum manus.
A kind of the advantages of finger joint prosthesis of the present invention, is：
1) prosthese of artificial knuckle can be replaced, the roughness on surface is strengthened, is conducive to Bone Ingrowth, to extend the prosthese longevity
Life, Using prosthesis is stable, facilitating operation, thus more suitable for practicality；
2) side's of being designed to handle structure, handle type are conducive to articulations digitorum manus blood supply, and are provided with vertical muscle, contribute to anti-rotation with convenient
Implantation；
3) it can ensure that the stability in joint replacement initial stage and later stage, reduce abrasion and the generation of friction particles；
4) internal material is implanted with good wearability and biocompatibility, by bone cement or biological fixation,
It can be with good stability；
5) articulations digitorum manus is superhigh molecular weight polyethylene material, and using the structure for meeting human dissection type, patient is applicable in
Range bigger.

As depicted in figs. 1 and 2, a kind of finger joint prosthesis of the present invention is shown as, including articulations digitorum manus 1 and metacarpophalangeal joints 2, is referred to
Joint 1 includes ball-and-socket head 11 and articulations digitorum manus shank 12, and ball-and-socket head 11 is fixedly linked with articulations digitorum manus shank 12, and articulations digitorum manus shank 12 leans on
The both sides at the nearly first end of ball-and-socket are provided with the first vertical muscle 13 of protrusion；Metacarpophalangeal joints 2 include bulb 21 and metacarpophalangeal joints shank 22,
Metacarpophalangeal joints shank 22 is fixedly linked with bulb 21, and metacarpophalangeal joints shank 22 is provided with protrusion close to the both sides of 21 one end of bulb
Second vertical muscle 23, the one end of metacarpophalangeal joints shank 22 far from bulb 21 is fixedly inserted in metacarpal bone to be connected with metacarpal bone, wherein, first
Vertical muscle 13 can be embedded in the second vertical muscle 23 in patient to prevent metacarpophalangeal joints 2 from rotating in patient with articulations digitorum manus 1, have
Anti-rotation, by fixed articulations digitorum manus 1 with metacarpophalangeal joints 2 to fix finger joint prosthesis.
Further, one end setting far from articulations digitorum manus shank 12 on 1 ball-and-socket head 11 of articulations digitorum manus is fluted, metacarpophalangeal joints 2
Bulb 21 can be included in groove, and bulb 21 can rotate that metacarpophalangeal joints 2 is driven to rotate relative to articulations digitorum manus 1 in groove.
