Abstract
The utility model relates to a temporal knee joint separator which contains antibiotic and is made of bone cement, and comprises a gasket made of bone cement containing antibiotic and a femur condylar shell; the gasket is in joint connection with the shell. When the utility model is in use, the gasket is fixedly connected with the top of the tibia and the shell is fixed on the bottom of the femur; joint movement is formed between the gasket and the shell; thereby, the knee joint separator and remain proper space for the artificial knee joint before the new knee joint is implanted again and reduce the scar generated during the interval between the two surgeries, the contracture of the joint capsule soft tissue and the disused bone loss, and sterilize the infected tissue; the knee join separator can provide joint movement to improve the quality of life of patients.
Description
Technical field
This utility model relates to a kind of interim knee joint barrier bodies of antibiotic-loaded bone cement that is used for replacing infected knee-joint prosthesis temporarily.
Background technology
The total knee replacement postoperative infection is the complication of the artificial knee joint replacement avoided of real difficulty, cause very big misery mentally can for the patient, causes very big loss economically, also poses a big pressure for the doctor.At present, the method of total knee replacement postoperative infection treatment is: at first take out the thorough debridement of original prosthese, utilize the interim knee joint barrier bodies of containing of manual preparation of antibiotic bone cement piece conduct to place joint to carry out disinfection, treat to insert new artificial knee joint once more after the infection control.Utilize the bone cement piece of this manual preparation to have Production Time length, can not make joint motion, and reduced and inserted new artificial knee joint operation possibility of success once more as interim knee joint barrier bodies.
The utility model content
The purpose of this utility model provides the interim knee joint barrier bodies of a kind of antibiotic-loaded bone cement that makes the joint have movable property.
For achieving the above object, this utility model is taked following design:
The interim knee joint barrier bodies of a kind of antibiotic-loaded bone cement is characterized in that it comprises: by containing pad and the condyle of femur shape housing that antibiotic bone cement is made, described pad is connected with articulated manner with housing.
The utility model has the advantages that: the interim knee joint barrier bodies of this utility model antibiotic-loaded bone cement, it comprises: by containing pad and the condyle of femur shape housing that antibiotic bone cement is made, pad is connected with articulated manner with housing.During use, spacers is connected the top of tibia, and housing is fixed in the bottom of femur, can provide articulation between pad and the housing.This shows, utilize this knee joint barrier bodies before inserting new artificial knee joint once more, to keep suitable joint space for new artificial knee joint, reduce cicatrix, joint capsule soft tissue contracture and the useless property the used bone loss of generation interval between the two operations, and can carry out disinfection to infection place, and this knee joint barrier bodies can provide articulation, improves patient's quality of life.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the interim knee joint barrier bodies of this utility model antibiotic-loaded bone cement is characterized in that it comprises: by containing pad 1 and the condyle of femur shape housing 2 that antibiotic bone cement is made, pad 1 and housing 2 are connected with articulated manner.
Pad 1 and housing 2 can utilize mould 5 compression moldings.Pad 1 profile is for approximate prismatic, and end face has cancave cambered surface, and the vertical view of pad 1 is shaped as the approximate shape of a hoof.Housing 2 bottom surfaces have the convex globoidal that matches with the end face of pad 1, and the vertical view of housing 2 is shaped as the approximate shape of a hoof.
As shown in Figure 4, during use, pad 1 is fixedly connected on the top of tibia 3, and housing 2 is fixedly connected on the bottom of femur 4, can provide articulation between pad 1 and the housing 2.
Claims (1)
1. interim knee joint barrier bodies of antibiotic-loaded bone cement is characterized in that it comprises: by containing pad 1 and the condyle of femur shape housing 2 that antibiotic bone cement is made, pad 1 and housing 2 are connected with articulated manner.
