Description
Technical field
The invention belongs to technical field of medical instruments, relate to the high abrasion interphalangeal joint prosthese of a kind of simple in construction, stable connection easy to use.
Background technology
Along with going from strength to strength of handicraft and mechanical industry, the incidence rate of labourer's hand injury increases year by year, wherein it is no lack of the impaired case of substantial amounts of interphalangeal joint to occur, additionally, 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.nullAt present，That treats interphalangeal joint network minimal refers to an arthrodesis，But finger function is lost and is seriously waited side effect day by day to highlight，This modus operandi can not meet the expectation demand of Most patients，Interphalangeal joint replacement and joint transplantation etc. can be had than the method for more completely reservation interphalangeal joint function，But joint transplantation is limited to the not enough and follow-up immunological rejection of donor and hinders its popularization，Therefore，At present，Artificial facet joint's prosthese of domestic application is still based on Swanson silicone，Wear-resistant use、Still have much room for improvement in impact resistant performance，Additionally the nearly distal securing portion in joint is particularly significant，The current interphalangeal joint postoperative life-span is the longest，Main is exactly fixing material and fixing means imperfection，Therefore，The high abrasion interphalangeal joint prosthese researching and developing a kind of stable connection has very important medical significance.
Summary of the invention
It is an object of the invention to provide the high abrasion interphalangeal joint prosthese of a kind of simple in construction, stable connection easy to use.
The object of the present invention is achieved like this, including joint sleeve and joint shaft, described joint sleeve arranges cylindrical groove and joint shaft rotatable engagement, described joint sleeve vertically and arranges connecting rod on cylindrical groove axis direction, arranging anchor ear in described connecting rod, on described joint shaft, vertical axis side sets up connecting rod, and described connecting rod arranges anchor ear, the arm of described anchor ear is perpendicular to connecting rod and arranges, and two arms are stretched out in structure of relatively filling the span of a man's arms from connecting rod.
The present invention arranges the joint sleeve with cylindrical groove, utilize cylindrical groove and joint shaft coordinates the rotary moveable function reaching interphalangeal joint, the surface of joint sleeve and joint shaft all arranges pyrocarbon coating, increase the wearability between joint sleeve and joint shaft and anti-collision, extend the service life of interphalangeal joint, connecting rod and anchor ear are made up of memorial alloy, under non-working condition, anchor ear is in amplification open configuration, when being under use state, excited by specified temp, anchor ear is held tightly, play fixing anti-skidding effect, present configuration is simple, easy to use, not only connect abnormal firm, and have and have good wearability, there is great promotional value.
