Abstract

The invention discloses a femoral handle fixed through expansion. The femoral handle comprises a femoral handle upper end, a handle body connected with the femoral handle upper end and a handle head connected with the handle body. The handle body is internally provided with an inner handle hole and a screw hole communicated with inner handle hole, the inner handle hole is internally provided with a push rod, the screw hole is internally provided with a screw connected with the push rod, and one end of the screw is provided with an inner square hole. By the femoral handle which is simple in structural design and convenient and rapid to operate, the problem of troubles brought to operation due to the fact that looseness or breaking apart easily occurs to an existing femoral handle during the operation is solved, so that the operation is more successful, success rate of the operation can be improved, and the femoral handle is more practical.

Description

Expansion resected femur handle
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of expansion resected femur handle.
Background technology
Existing femoral stem operation can only be selected in several fixedly specifications, can only select to approach the femoral stem of model, size can not be closed reality fully, so femoral stem just there will be unavoidably loosening or two kinds of situations of spalling in operation, bring very burden to operation, even need to carry out second operation.This situation can be brought very large misery to the patient, and has extended the time of postoperative rehabilitation.Therefore design a kind of simple in structurely, convenient to use, and therefore can improve the femoral stem of success rate of operation, become the problem that current industry need to solve.
Summary of the invention
The purpose of this invention is to provide a kind of expansion resected femur handle, solved existing femoral stem and problem loosening or that spalling makes troubles to operation easily occurs in operation.
The technical solution adopted in the present invention is: expansion resected femur handle, the handle body that comprise the femoral stem upper end, with the femoral stem upper end, is connected and the button be connected with the handle body, the screw that is provided with the handle endoporus in the handle body and communicates with the handle endoporus, be provided with push rod in the handle endoporus, be provided with the screw rod be connected with push rod in screw, screw rod one end is provided with interior cubic perforate.
Characteristics of the present invention also are,
Button is 120 ° of three opening button.
The button front end has 90 ° of teeth.
The push rod front end is the taper thimble, and the handle diameter of bore is not less than the push rod diameter, and the handle diameter of bore is determined according to the femoral stem model.
Screw and screw diameter are complementary, and screw and screw diameter are determined according to the femoral stem model.
Interior cubic perforate also can be interior six side's perforates.
Its principle is screw rod screw forward, makes the taper thimble back down 120 ° of three opening button, and 120 ° of three opening button opens to three directions, and 90 ° of teeth are fixed on the inwall of bone hole, prevents that femoral stem from gliding.
The invention has the beneficial effects as follows: the present invention's resected femur handle that expands, solved existing femoral stem and problem loosening or that spalling makes troubles to operation easily occurred in operation, structural design is simple, simple operation, perform the operation more smooth, can improve success rate of operation, thereby more be suitable for practicality.
The accompanying drawing explanation
Fig. 1 is the expand structural representation of resected femur handle of the present invention;
Fig. 2 is the expand A-A ' cutaway view of resected femur handle button of the present invention.
In figure, 1. femoral stem upper end, 2. handle body, 3. button, 4. handle endoporus, 5. screw, 6.90 ° of teeth, 7. push rod, 8. screw rod, 9. taper thimble, 10. interior cubic perforate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The present invention's resected femur handle that expands, structure as shown in Figure 1, the handle body 2 that comprise femoral stem upper end 1, with femoral stem upper end 1, is connected and the button 3 be connected with handle body 2, button 3 is 120 ° of three opening button, and button 3 front ends have 90 ° of teeth 6, the screw 5 that is provided with handle endoporus 4 in handle body 2 and communicates with handle endoporus 4, be provided with push rod 7 in handle endoporus 4, be provided with the screw rod 8 be connected with push rod 7 in screw 5, screw rod 8 one ends are provided with interior cubic perforate 10, and interior cubic perforate 10 also can be interior six side's perforates.
Push rod 7 front ends are taper thimble 9, and handle endoporus 4 diameters are not less than push rod 7 diameters, and handle endoporus 4 diameters are determined according to the femoral stem model.
Screw 5 is complementary with screw rod 8 diameters, and screw 5 and screw rod 8 diameters are determined according to the femoral stem model.
Its principle is screw rod 8 screw forward, makes taper thimble 9 back down 3,120 ° of three opening button 3 of 120 ° of three opening button and opens to three directions, and 90 ° of teeth 6 are fixed on the inwall of bone hole, prevents that femoral stem from gliding.
During use, at first select to insert smoothly the femoral stem model in bone hole, push rod 7 is contained in handle endoporus 4, screw rod 8 is contained in screw 5.During operation, hold femoral stem upper end 1, femoral stem is inserted into to the bone hole to optimum position, with the interior cubic perforate 10 of interior cubic spanner rotary screw 8 one ends, make screw rod 8 head on push rod 7 and travel forward, when the taper thimble 9 of push rod 7 front ends moves to button 3 front end, the taper thimble 9 of push rod 7 front ends can back down 120 ° of three opening button 3,120 ° of three opening button 3 opens to three directions, and 90 ° of teeth 6 of button 3 front ends will be fixed on the inwall of bone hole, have prevented the downslide of femoral stem.
The present invention's resected femur handle that expands has solved existing femoral stem problem loosening or that spalling makes troubles to operation easily occurred in operation, and structural design is simple, and simple operation is performed the operation more smooth, can improve success rate of operation, thereby more be suitable for practicality.
