Abstract
The utility model relates to the design of a novel artificial joint which is provided with a bionic artificial joint capsule. The aim of the utility model is to provide an artificial joint with good lubrication and little wear. Compared with the prior art, the utility model designs the artificial joint capsule and an artificial joint cavity, namely that a storing mechanism and an antiseep mechanism are designed in the system of the artificial joint. Synovia and wear particles are sealed in the bionic artificial joint capsule. The utility model can not only solve the problem of storing the synovia, but also prevent the wear particles which are produced by materials of the artificial joint from seeping in a body. Therefore, the foreign body reaction is avoided. The utility model is likely to solve the main problem which influences the service life of the artificial joint, and therefore, the service life of the artificial joint is prolonged obviously.
Description
Technical field
This utility model relates to a kind of design with the novel artificial joint of " biomimetic prosthetic joint capsule ".
Background technology
People's joint is the special organ of a class, is the not only bio-tribology system of transmitted load but also transmitting movement.People's joint is made up of the joint capsule of articular surface, ossa articularia, cartilage, knuckle synovia and supply synovial fluid, is the tribology system of very marvellous and an excellent performance.Though the working condition of human synovial most evil bad (particularly joint of the lower extremity), the tribological property of this system shows superiorly unusually, and coefficient of friction is minimum, and does not almost have wearing and tearing, can work more than 70 years usually.Certainly also accident can appear, and the one, objective and subjective reason causes articular system generation pathological changes, forms arthritis, causes that the knuckle synovia secretory volume reduces, insufficient lubrication, the serious even artificial joint that will change the outfit; The 2nd, wound disables, and loses its function, or suffers from the osteoma excision, and artificial joint also will change the outfit.Calculate that according to investigation China has 100～1,500,000 joint patients need do artificial operation on joint.Therefore, prolong artificial joint service life, improve its biocompatibility, be the big problem that is related to millions upon millions of person health.
At present, existing artificial joint does not design the function of supply synovial fluid and storage synovial fluid, and the tissue fluid that just depends on the non-constant of lubricity is lubricated, thereby joint rubbing surface serious wear, and wear extent is big.Simultaneously, the foreign body reaction that is caused by wear particle can shorten artificial joint service life.Discovering in recent years, it is relevant that become flexible the foreign body reaction that constantly increases in a large number and cause with wear particle (abrasive dust) late period of artificial joint, because a large amount of abrasive dusts can cause that macrophage and mononuclear cell gather in a large number, and produce the various kinds of cell factor and cause osteoblast and osteoclast unbalance on formation, quantity and metabolic function, bring out bone resorption, thereby cause the bone dissolving very serious, thereby make prosthetic loosening, sinking, lose its motor function, must undergo surgery and overhaul, this has brought huge misery and economic loss to the patient undoubtedly.For this reason, done a large amount of research both at home and abroad on artificial joint design, material and face coat, expectation changes pair materials and reduces wear and abrasive dust, but does not significantly improve the artificial joint lubrication state, and the relevant issues that wear particle causes still exist in a large number.
Summary of the invention
The purpose of this utility model is the to provide a kind of little artificial joint that lubricates, weares and teares.
Artificial joint and human body natural joint major different are: at first artificial joint is the friction pair that has replaced ossa articularia (comprising articular surface and cartilage) to form with the friction pair that metal, macromolecular material or ceramic material are formed; Secondly, artificial joint lacks the joint capsule that has secretion and storage synovial fluid function in the human synovial.Thereby artificial joint shortage synovial fluid that adapt with it, that have the excellent tribology characteristic is lubricated.
In recent years, both at home and abroad the medical expert is at the lighter early stage arthritis case of symptom, tentatively realized by extracting necrosis repeatedly joint fluid, inject aqueous solution of sodium hyaluronate or other synovial fluid with keep articular system normal lubricated, repair the clinical case of diseased joints.For this reason, this utility model considers that the bionical synovial fluid will have biocompatibility introduces the artificial joint system, realizes the manual application of lubricant, thereby for prolonging the service life of artificial joint, reduces wear, abrasive dust amount and reduce the abrasive dust particle diameter and seek new approach and theory.
For achieving the above object, this utility model adopts following technical proposals:
A kind of artificial joint comprises the artificial joint bone, it is characterized in that: also comprise artificial joint capsule, artificial joint chamber, described artificial joint capsule is coated on the periphery of artificial joint bone, constitutes an artificial joint chamber between this artificial joint capsule and artificial joint bone.
Described artificial joint capsule adopts the viscoelasticity medical macromolecular materials.
Described viscoelasticity medical macromolecular materials can be silica gel, polyvinyl alcohol, chitosan.
Described artificial joint intracavity can be stored synovial fluid.
Described artificial joint comprises artificial joint of the lower extremity, artificial hip joint.
Compared with prior art, this utility model has designed artificial joint capsule and artificial joint chamber, promptly in the artificial joint system, design a storage, antiseep mechanism, this " biomimetic prosthetic joint capsule " all is sealed in synovial fluid and wear particle wherein, not only can solve the storage problem of synovial fluid, but also can prevent that the wear particle seepage that artificial joint material produces from entering in the body, can avoid foreign body reaction, be expected to solve the present subject matter that influences the artificial joint life-span, thereby can prolong the service life of artificial joint more significantly.

1---the artificial joint bone; 2---the artificial joint capsule; 3---the artificial joint chamber
The specific embodiment
As shown in Figure 1, a kind of artificial knee joint comprises artificial joint bone 1, artificial joint capsule 2, artificial joint chamber 3, and described artificial joint capsule 2 is coated on the periphery of artificial joint bone 1, constitutes an artificial joint chamber 3 between this artificial joint capsule 2 and artificial joint bone 1.Can store synovial fluid 4 in the described artificial joint chamber 3.Described artificial joint capsule's 2 material should satisfy biocompatibility, long-life, resisting fatigue, not influence human synovial and requirements such as normal activity on every side thereof, can adopt the viscoelasticity medical macromolecular materials, as silica gel, polyvinyl alcohol, chitosan etc.
