Abstract
The utility model discloses a joint all-antibiotic bone cement occupier molding press, comprising at least two molds with grooves, and connectors between the molds, wherein when the molds are connected together, a chamber formed by the grooves has joint shape. The utility model uses antibiotic bone cement to produce occupier, to provide high-density antibiotic locally, and since the mold surface is smooth, the shaped occupier has smooth surface as metal occupier. Therefore, the utility model has the advantages as local drug feeding of cement occupier and smooth surface of metal occupier, with simple operation.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to the full antibiotic-loaded bone cement occupying device of a kind of joint type swager.
Prior art
The artificial joint replacement postoperative infection is a kind of catastrophic complication, and treatment is difficulty very.The treatment of relatively generally acknowledging is to carry out second operation at present: artificial joint prosthesis is taken out in operation for the first time, and carries out debridement completely; Wait for then and go second operation after the infection control again, implant new prosthese.
After the debridement first time, the empty position that takes out prosthese should use a kind of thing to occupy, otherwise periarticular soft tissues can contracture cause difficulty for the operation second time, also can influence the function in joint simultaneously.
Begins to have and adopt the metal occupying device, but the metal occupying device is a kind of foreign body that can not continue provides antibiotic to the part, unfavorable to control infection.
Useful afterwards antibiotic-loaded bone cement piece, this occupying device can provide the antibiotic of high concentration to the part, but stiff when using in knee joint, still can cause the contracture of knee joint peripheral soft tissue, influences the function of joint behind the second operation; And, also can cause further bone loss because do not match with the surrounding bone tissue morphology, also have the possibility of occupying device dislocation.Therefore people have attempted femoral component again and have adopted the original prosthese of sterilizing in the knee joint treatment of infection, or use new metal prostheses, and tibia partly adopts the antibiotic-loaded bone cement occupying device with the hands kneading, though this occupying device can make patient's knee joint carry out activity between two operations, reduced the generation of knee joint peripheral soft tissue contracture, occupying device dislocation and the further generation of bone loss have also been reduced, but introduced metallic foreign body again, control infection has been caused difficulty again.
Therefore preferably all adopt the antibiotic-loaded bone cement occupying device, so both do not had metallic foreign body, can keep periarticular soft tissues not produce contracture again, do not produce occupying device dislocation and further bone loss at femoral component and tibia part.If yet femoral component also adopts the antibiotic-loaded bone cement occupying device, the problem that so at first runs into is that how to obtain can active smooth track, if pinching with hands in art is the track of impossible acquisition and tibia occupying device coupling, can not be complementary with the femur contact surface simultaneously, pinch with hands in addition and can not guarantee that size is consistent with tibia and femur surface of bone, so just need in art, repair and adjust again, delay operating time.
Summary of the invention
In view of this, the purpose of this utility model be to provide a kind of can be according to the full antibiotic-loaded bone cement occupying device of the joint type swager of distal femur and proximal tibia size customization antibiotic-loaded bone cement occupying device, so both saved the time in the operation, can obtain slick Gliding joint face again, and can provide the antibiotic of high concentration to be beneficial to the control of infection in localized sustained.
For achieving the above object, the technical solution of the utility model is: the full antibiotic-loaded bone cement occupying device of a kind of joint type swager, it is characterized in that comprising the bindiny mechanism between two or more reeded mould and the mould, the cavity that is formed by groove when these moulds link together has the osteoarticular shape of part.
Described bindiny mechanism can be known various bindiny mechanism.In a kind of preferred embodiment, described bindiny mechanism is selected from hinge, hinge, pin and combination thereof.More preferably described bindiny mechanism comprises hinge and pinning.
Described mould can be made of a variety of materials.In a kind of preferred embodiment, described mould is made by rustless steel.
Described osteoarthrosis can be various osteoarthrosis.In a kind of preferred embodiment, described osteoarthrosis is selected from knee joint and hip joint.
The full antibiotic-loaded bone cement occupying device of joint type of the present utility model swager uses antibiotic-loaded bone cement to make occupying device, and the antibiotic of high concentration can be provided to the part; And because die surface is smooth, it has the smooth surface not second to the metal occupying device after the occupying device molding; Like this, this utility model just promptly possesses the advantage that the cement occupying device can topical, possesses the ganoid advantage of metal occupying device again, and uses very simple and convenient.
Description of drawings
Fig. 1 is the full antibiotic-loaded bone cement occupying device of the joint type swager cutaway view that hip joint of the present utility model uses.
The femoral joint type full antibiotic-loaded bone cement occupying device swager cutaway view of Fig. 2 for using in the knee joint of the present utility model.
The tibial prosthesis type full antibiotic-loaded bone cement occupying device swager cutaway view of Fig. 3 for using in the knee joint of the present utility model.
Among the figure: symbol 1 is represented pinning, and symbol 2 is represented groove, and symbol 3 is represented hinge.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is elaborated.
As shown in the figure: the full antibiotic-loaded bone cement occupying device of a kind of joint type of the present utility model swager includes mould, pinning 1, and the hinge 3 of groove 2.
During use, adopt Palacos G to contain the gentamycin bone cement, add 7.5% vancomycin therein, bone cement polymerization after being in harmonious proportion adds in the swager extrusion modling in the agglomerating phase.Use between swager and bone cement ethanol to smear to prevent that bone cement and swager are bonded together can't take out the antibiotic-loaded bone cement occupying device that suppresses, treat after the bone cement full solidification antibiotic-loaded bone cement occupying device to be taken out, the antibiotic-loaded bone cement with the other synthetic agglomerating phase is fixed to antibiotic-loaded bone cement on the corresponding osseous tissue then.
