The weary impaired case of substantial amounts of interphalangeal joint occurs, it addition, rheumatoid arthritis, infection, tumor resection or congenital diseases etc.
Cause one of factor of hand palm interphalangeal joint defect, these functions all having a strong impact on hands and profile for the moment.At present, treatment refers to
Between joint network minimal refer to an arthrodesis, but finger function is lost and serious is waited side effect day by day to highlight, this hands
Art mode can not meet the expectation demand of Most patients, it is possible to has than the method more completely retaining interphalangeal joint function
Interphalangeal joint replacement and joint transplantation etc., but joint transplantation is limited to the not enough and follow-up immunological rejection of donor and hinders
It is promoted, and therefore, at present, artificial facet joint's prosthese of domestic application is still based on Swanson silicone, anti-use
Still have much room for improvement in abrasion, impact resistant performance, the interphalangeal joint that additionally the nearly distal securing portion in joint is particularly significant, current
The postoperative life-span is the longest, is exactly mainly fixing material and fixing means imperfection, and therefore, the high abrasion researching and developing a kind of stable connection refers to
Between articular prosthesis there is very important medical significance.
Summary of the invention
It is an object of the invention to provide the high abrasion interphalangeal joint vacation of a kind of simple in construction, stable connection easy to use
Body.
The object of the present invention is achieved like this, and including joint sleeve and joint shaft, described joint sleeve arranges cylindrical groove and pass
Nodal axisn rotatable engagement, described joint sleeve vertically and arranges connecting rod on cylindrical groove axis direction, described connecting rod arranges barb
Thorn, on described joint shaft, vertical axis side sets up connecting rod, and described connecting rod arranges Rubus delavayi Franch..
The present invention is arranged has the joint sleeve of cylindrical groove, and utilize cylindrical groove and joint shaft coordinates the rotation reaching interphalangeal joint
Turning the surface of movable function, joint sleeve and joint shaft and all arrange pyrocarbon coating, increase between joint sleeve and joint shaft is wear-resisting
Property and anti-collision, extend interphalangeal joint service life, connecting rod and Rubus delavayi Franch. are made up of memorial alloy, at non-working condition
Under, Rubus delavayi Franch. is in thorn groove, when being under use state, specified temp excites, and Rubus delavayi Franch. is holded up, and plays anti-skidding effect,
Present configuration is simple, easy to use, not only connects abnormal firm, and has and have good wearability, has popularization greatly
It is worth.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings, but must not be any limitation as the present invention by any way,
Based on present invention teach that any change or improvement made, belong to protection scope of the present invention.
As shown in Fig. 1 ~ 6, the present invention includes that joint sleeve 1 and joint shaft 2, described joint sleeve 1 arrange cylindrical groove and joint shaft 2
Rotatable engagement, described joint sleeve 1 vertically and arranges connecting rod 3 on cylindrical groove axis direction, described connecting rod 3 arranges Rubus delavayi Franch.
4, on described joint shaft 2, vertical axis side sets up connecting rod 3, and described connecting rod 3 arranges Rubus delavayi Franch. 4.
Described joint sleeve 1 and joint shaft 2 surface configuration pyrocarbon coating, increase the wearability of interphalangeal joint, extends and uses
Life-span.
The anisopleual setting of cylindricality notch of described joint sleeve 1, extended limit in a side port of described cylindricality notch
Position shelves dial 12, and the connecting rod 3 that spacing shelves are dialled on 12 pairs of joint shafts 2 carries out spacing, make the connecting rod 3 on joint shaft 2 and joint sleeve 1
On gag lever post 3 between angle be 10 ° to the maximum；The side of postive stop baffle it is not provided with, on joint shaft 2 on described cylindricality notch
Connecting rod 3 opposed articulation set 1 on the movable angle of connecting rod 3 can reach-90 °.
The cylindricality notch both sides of described joint sleeve 1 are set to symmetrical structure, are disposed radially stopper slot in described cylindrical groove
