Description
Technical field
The present invention relates to a kind of medical aid, a kind of adjustable distal femur tumor resection auxiliary is particularly related to
Device.
Background technology
Distal femur is malignant bone tumor predilection site, for the patient with tumour, and precise ablation tumour is its treatment
Key；Generally for tumor resection, it is necessary to model precisely to determine that tumour is cut from three dimensions using area of computer aided
Except scope, and tumor resection and reconstruction operations are accurately guided by distal femur tumor resection servicing unit；Existing 3D is beaten
The personalized tumor resection servicing unit of the distal femur of print is typically the shape of the distal femur tumour according to each patient
Shape is by one matched device of CAD design, because the device is a kind of fixed structure, it is impossible to adjust its structure
Size, it is impossible to be adjusted according to tumour height and length, therefore be only capable of every time using once, cause the very big wave of medical device
Take, and aggravated patient economy burden.
The content of the invention
The present invention proposes a kind of distal femur tumor resection servicing unit adjustable, dismountable, easy to operate.
The technical proposal of the invention is realized in this way：
A kind of adjustable distal femur tumor resection servicing unit that the present invention is provided, including fixed component one is with consolidating
Determine part two；One support member one is fixed in fixed component one, and support member one can be moved up and down along fixed component one；One
Support member two is fixed in fixed component two；One cross bar one is fixed in support member one；A connection piece is fixed on supporting part
On part two, and its one end can be moved up and down along support member two, and the other end is connected with cross bar one, and cross bar one can be along connector level
It is mobile.
A kind of adjustable distal femur tumor resection servicing unit that the present invention is provided, by fixed component one and admittedly
Determine the tumour both sides that part two is fixed on distal femur, because cross bar one can be moved horizontally along connector, therefore can be according to swollen
Knurl invades profit length and adjusts width between the two；And support member one can be moved up and down along fixed component one, connector can edge
Support member two is moved up and down, therefore can be aided according to tumour height by the regulation that moves up and down of support member one and connector
The height of device, therefore the servicing unit that the present invention is provided can adjust dress according to the tumor size of different patient's distal femurs
The width put and height, so as to guide accurate tumor resection, because it is detachable adjustable, therefore can recycle, reduce
Medical appliance pollutes, and reduces medical treatment cost.
