Description
Technical field
The present invention relates to a kind of artificial joint, particularly a kind of artificial hip joint.
Background technology
Artificial joint replacement is one of most important progress of obtaining at twentieth century of orthopaedics field; Artificial joint replacement has been widely used in treating the disease of shoulder joint, elbow joint, carpal joint, interphalangeal joint, hip joint, knee joint and ankle joint etc. at present, is one of field that investment is maximum in the orthopedia over nearly 30 years, development and change are the most outstanding.Wherein general with the marrow joint, be replaced as power over nearly 10 years and surpass 90%, extensively to use clinically, it is made over can only the dependance on walking stick walking, even the disabled arthrosis patient dream freely that realizes walking.
Artificial joint replacement is comprising that China generally promotes.The main external manufacturer of several families has occupied whole artificial joint market and has surpassed 60% the market share, like Depuy, and Zimmer, Smith, brand products such as Stryker are the products that the doctor the most often uses in the joint replacement surgery.Mostly homemade artificial joint product be that the technical parameter of reference inlet port joint product is imitated and form, though also occupy certain market share since technology with lack research and development and drop into, make and a lot of doctors and be not inclined to selection only start from the consideration of price.
Yet the joint product of American-European manufacturer is by the design of west ethnic group, the anatomical features and the living habit of being partial to the westerner.Since compatriots and west patient ethnic group and cultural aspect different; Cause hip joint to exist comparatively significant difference at aspects such as anatomic form, daily behavior action and body mechanics's characteristics, medical circle reflects that generally existing USA and Europe artificial joint product can not adapt to domestic patient's needs well.
State's human femur geometric parameter and white people have significant difference; For example: there is notable difference in parameters such as distance, collodiaphyseal angle, acetabular bone top rake, angle of splay between femur/pulp cavity modality curves, offset, femoral head center and greater trochanter point level height, and these parameter determining design/arrangement etc. that femur biomechanics characteristic, artificial thigh bone center should have position, acetabular component.Because import artificial hip joint product is according to the hip joint parameter designing of west ethnic group; Can not form the dissection coupling with being distinguished skeleton as a rule, therefore require the doctor when compatriots are carried out the import hip replacement, should note prosthese and state's human femur differences.
Summary of the invention
The purpose of this invention is to provide the artificial hip joint that is complementary with compatriots' hip joint anatomical features.
