Abstract
The utility model relates to a measuring scale for femur of a semi-hip replacement prosthesis. The end part tooth shape of the measuring scale can effectively and accurately measure the size of a femoral head, and the measurement accuracy is improved. A spring is arranged in the middle of the measuring scale, the measurement range can be conveniently and quickly controlled, the tail end of the measuring scale is provided with a driving indication device, and a pointer is indicated within the scale range through the tensioning force of the spring, therefore a corresponding prosthesis model is selected according to readings.
Description
Technical field
This utility model relates to the survey tool in a kind of half hip replacement operation, refers to especially be used to measure capital dip stick in a kind of half hip operation.
Background technology
Half hip replacement prosthese dip stick is to be used for the patient is carried out half hip when operation, the survey tool of use.The rationalization degree direct influence doctor of its design is to the judgment and the implementation capacity of human body operation.How designing convenient, fast, effective surgery operation tool, is all highest goals of making the subjoint field of surgery.
In the existing partial hip joint replacement operation, because artificial fracture causes replacement prosthesis, acetabular fossa is not repaired during displacement, only femoral head is taken out from acetabular fossa, intercept femoral head then and change prosthese, the acetabular fossa place implants double motion head.Be to use slide gauge that the femoral head of intercepting is measured but choose the double motion head specification in the operation, thereby choose corresponding specifications and models.Because slide gauge can not intuitively, quick, simple and effective be matched, increase the probability of error easily, thereby prolong operating time.
In sum, design and aly be used for the instrument that half hip operation is measured femoral head, thereby conveniently cooperate doctor's operation that undergos surgery.
The utility model content
The purpose of this utility model is exactly in order to provide one better more effectively to be used to replace half hip prosthesis and to measure capital instrument.
For achieving the above object, this utility model is taked following design:
A kind of implantation half hip replacement prosthese formula femoral head dip stick, make by the 1Cr18Ni9 material, its top is divided into measured zone, is measurement size reading and operating area below, it is characterized in that, measured zone is the zigzag contact surface, with rivet with its riveting on driving body, middle run through by pin, it is centered on a bit does back and forth movement, indicating device be separately with the rivet riveting on driving body, pointer slided in the indicating area and carry out reading.
The utility model has the advantages that:
1, this utility model is simple in structure, and preparation is easy, and dip stick measuring junction dentation can be measured the femoral head size effectively accurately, increases certainty of measurement.
2, place a spring in the middle of the dip stick, conveniently control survey scope makes the dip stick tensioning freely.
3, the dip stick afterbody, makes the pointer indication in the scale zone, thereby carries out reading, and choose corresponding prosthese model by playing the zither tensile force for driving indicating device.
Description of drawings
Fig. 1 is a utility model structural representation front view;
Fig. 2 is a utility model structural representation vertical view;
The specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described in further details.
As shown in Figure 1 and Figure 2, a kind of partial hip joint replacement operation that is used for is measured capital dip stick, form by main scale 1, spring 2, back-up ring 3, pin 4, secondary chi 5, pointer 6, claw 7, corresponding scale is carved with in the main scale lower end, make things convenient for reading, claw 7 is two upper ends of using pin rivet at main scale 1 and secondary chi 5 respectively, again with the lower end of pointer 6 usefulness pin rivets at secondary chi, at last spring 2 is placed into the centre of main scale 1 and secondary chi 5, fix with back-up ring 3 and pin 4 respectively, each part assembling cooperates the back using again.
This utility model is made with the 1Cr18Ni9 material.
This utility model in use, dip stick claw 7 is stuck in the thickness of the human femoral head after the intercepting, with driving main scale 1, secondary chi 5 on hand down, tensile force by spring 2, firmly block human femoral head, the pointer 6 of dip stick lower end can be according to the size of human femur under loading, with the corresponding scale of pointed, according to the scale indication, choose corresponding product standard and type then.Half hip replacement prosthese femur dip stick of the present utility model can farthest convenient, fast, effectively be measured human femoral head, reduces operating time.
Claims (1)
1. one and half hip replacement prosthese femur dip sticks, make by the 1Cr18Ni9 material, its left part is divided into measured zone, and right part is divided into measurement size reading zone and operating area, it is characterized in that, measured zone is the zigzag contact surface, with rivet with its riveting on driving body, middle run through by pin (4), it is centered on a bit does back and forth movement, indicating device be separately with the rivet riveting on driving body, pointer (6) slided in the indicating area and carry out reading.
