Abstract

The invention provides a hip joint prosthesis. The hip joint prosthesis comprises a femoral-stem proximal portion, an extending stem and a filling component. The filling component is disposed betweenthe femoral-stem proximal portion and the extending stem, so as to connect the femoral-stem proximal portion with the extending stem. The filling component comprises a first adjusting portion and a filling member, the first adjusting portion and the filling member are detachably connected, the first adjusting portion is used for being connected with the extending stem, and the filling member is used for being connected with the femoral-stem proximal portion. The filling member comprises a second adjusting portion, the second adjusting portion comprises a telescopic portion, the movably disposed telescopic portion is pushed to move to increase the area of the peripheral surface of the second adjusting portion, the peripheral surface of the second adjusting portion can fit and contact a bonedefect position of a corresponding hip joint, and accordingly, the second adjusting portion is well matched with the bone defect position of the corresponding hip joint. The hip joint prosthesis canmeet different bone defect conditions of the hip joint, thereby having high universality.

Description

technical field [0001] The invention relates to the medical field, in particular to a hip joint prosthesis. Background technique [0002] With respect to total hip revision, the primary replacement prosthesis and diseased bone must be removed during revision, which will result in a certain degree of bone defect, and the location and degree of bone defect vary from person to person. [0003] Hip joint prosthesis is usually needed to deal with the bone defect of the total hip joint. The structure of the filling part of the existing hip joint prosthesis is relatively fixed and the flexibility is poor, which cannot be adjusted according to the position and degree of bone defect. Adjust it appropriately so that it fills well. Although it is possible to tailor the hip joint prosthesis to the patient so that the filling parts can better match the bone defect of each patient, so as to meet the needs of each patient, the custom-made hip joint prosthesis takes a long time and is expe...
