Abstract

The invention relates to a modularized manual acetabulum cup which is arranged in an acetabular fossa and used for connecting an artificial thighbone bulb. The modularized manual acetabulum cup comprises a bowl-shaped semicircular acetabulum cup and an extending shell, wherein the acetabulum cup is provided with an outer circumferential surface contacting with the acetabular fossa and an inner circumferential surface connected with the artificial thighbone bulb, and one side edge of the outer circumferential surface protrudes out of the acetabular fossa and is provided with a first connecting part; the extending shell is provided with a second connecting part jointed with the first connecting part; the extending shell is provided with an abutting surface attached to the bone wall near the acetabular fossa, a jointing surface connected to a plane formed by an opening of the acetabulum cup and an outer plane connected with the jointing surface and provided with an angle relative to the jointing surface; and the extending shell is provided with a plurality of positioning holes penetrating through the abutting surface and the outer plane. In the invention, different sizes of extending members are combined to be attached to various acetabulum cups with acetabular fossa shapes, therefore, different sizes of extending shells are produced to meet the requirements on various patients by changing the angle of the jointing surface relative to the abutting surface.

Description

technical field [0001] The invention relates to a modular artificial acetabular cup, in particular to a modular artificial acetabular cup which can satisfy various acetabular bone shapes by utilizing combined components of different sizes. Background technique [0002] The hip joint is an important joint that bears more than half of the weight of the human body. However, the hip joint is also prone to hip joint diseases with age, trauma, or inflammation. The main reason is that the femoral head cartilage is severely worn or The femoral head is deformed, resulting in the inability of the hip joint to move normally, further causing the patient's normal limb movement due to pain and discomfort, and severe cases may even lose the ability to move. [0003] The most common treatment for the above-mentioned hip joint lesions is total artificial hip replacement to reconstruct the normal function of the hip joint, and the components of the total artificial hip joint used in this oper...
