Abstract
The utility model is an improved artificial hip joint metal cotyle, which comprises a metal outer cup and a plastic lining. The utility model is characterized in that the metal outer matched surface of the plastic lining is provided with an inversing button. Known by the above mentioned improvements, as the inversing button is installed on the matched surface of the metal outer cup, the plastic lining is inversely buttoned by the inversing button installed on the matched surface of the metal outer cup when pressed; under the outer forcing, the deduction is gradually becoming tight; the plastic liner is in stably fixed in the cavity of the metal cotyle metal cup; thus the utility model avoids producing fretting, rotating and shedding to achieve the fixed effect and eliminate the physiological burden of the patients. The utility model is used for human disease to the hip bone replacement surgery.
Description
Affiliated technical field
This utility model relates to the artificial joint of medical domain.Particularly a kind of improved artificial hip joint metal acetabular bone.
Background technology
Artificial hip joint metal acetabular bone comprises outer cup of metal and plastic inner lining, all is body implants.The alternative of implant into body hip joint when being used for the human hip pathological changes and need carrying out the orthopaedics replacement operation makes patient recover the physiological function of hip joint to a certain extent, and alleviating pain improves motion and improves the quality of living.In prior art, the outer cup of metal is to adopt to screw in assembly structure with the plastic inner lining assembling, easily produces fine motion and rotation.Increase the mortality of replacement, increased the weight of patient's physiological load.
Summary of the invention
The purpose of this utility model is to provide a kind of outer cup of metal and plastic inner lining of improved artificial hip joint metal acetabular bone, and the outer cup of metal that can overcome existing artificial hip joint metal acetabular bone produces the defective of fine motion and rotation with the plastic inner lining assembling; Reach the success rate that increases replacement, prolong product service life, alleviated patient's physiological load.
Task of the present utility model realizes by this way: this artificial hip joint metal acetabular bone outside metal cup with face that plastic inner lining cooperates on back-off is set.
By above-mentioned improvement as can be known, owing to outside metal, on the mating surface of cup back-off is set, when plastic inner lining is pressed into, the back-off that is set at the outer cup of metal mating surface fastens, button is tight more more under external force, stably be fixed on the interior intracavity of the outer cup of metal acetabular bone metal, make it to produce fine motion, rotate and come off, reach fixed effect.
When implementing this utility model, described back-off height is 0.01～5 millimeter, wide be 0.01～10 millimeter proper, back-off Tai Gaotai is wide can to strengthen assembly difficulty, too low too narrow then act on not obvious.
Description of drawings
Fig. 1 is the sketch map of a kind of concrete structure of this utility model
Fig. 2 is the back-off enlarged drawing
The specific embodiment
As depicted in figs. 1 and 2: the outer cup of metal of this utility model that outer cup 1 of metal acetabular bone metal and plastic inner lining 2 and back-off 3 are formed and existing artificial hip joint metal acetabular bone is basic identical with the plastic inner lining physical dimension, and the implantation mode is identical.Its difference is on 1 and mating surface plastic inner lining 2 of cup back-off 3 to be set outside metal acetabular bone metal, and the quantity of back-off 3 is 6, and height is 1 millimeter, and wide is 1 millimeter.The outer cup 1 of the metal of this artificial hip joint metal acetabular bone is to adopt the metal vacuum essence of human implantable to cast disjunctor to make with 3, also can adopt the isothermal forging disjunctor to make, also can adopt machine-tooled method to make, plastic inner lining 2 is to adopt the ultra-high molecular weight polyethylene mold pressing to make, and also can adopt machine-tooled method to make.
