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
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 fixing specification, can only select the femoral stem close to model, size can not close reality completely, loosens or spalling two kinds of situations so femoral stem just there will be unavoidably in operation, bring very burden to operation, even need to carry out second operation.This situation can bring very large misery to patient, and extends the time of postoperative rehabilitation.Therefore a kind of structure is designed simple, convenient to use, and therefore can improve the femoral stem of success rate of operation, become the problem that current industry needs to solve.
Summary of the invention
The object of this invention is to provide a kind of expansion resected femur handle, solve existing femoral stem in operation, easily occur that loosening or spalling brings troublesome problem to operation.
The technical solution adopted in the present invention is: expansion resected femur handle, the button comprising femoral stem upper end, the handle body be connected with femoral stem upper end and be connected with handle body, the screw being provided with handle endoporus in handle body and communicating with handle endoporus, push rod is provided with in 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.
Feature of the present invention is also,
Button is 120 ° of three opening button.
There are 90 ° of teeth button front end.
Push rod front end is taper thimble, and handle diameter of bore is not less than push rod diameter, and handle diameter of bore is determined according to femoral stem model.
Screw and screw diameter match, and screw and screw diameter are determined according to femoral stem model.
Interior cubic perforate also can be interior six side's perforates.
Its principle is screw rod screw forward, makes 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 bone hole inwall, prevent femoral stem from gliding.
The invention has the beneficial effects as follows: the present invention is expanded resected femur handle, solve existing femoral stem and easily occur loosening in operation or spalling brings troublesome problem to operation, structural design is simple, simple operation, perform the operation more smooth, can success rate of operation be improved, thus more be suitable for practicality.
Accompanying drawing explanation
Fig. 1 is that the present invention is expanded the structural representation of resected femur handle;
Fig. 2 is that the present invention is expanded the A-A ' sectional view of resected femur handle button.
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 rods, 9. taper thimble, cubic perforate 10..
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The present invention is expanded resected femur handle, structure as shown in Figure 1, the button 3 comprising femoral stem upper end 1, the handle body 2 be connected with femoral stem upper end 1 and be connected with handle body 2, button 3 is 120 ° of three opening button, and there are 90 ° of teeth 6 button 3 front end, the screw 5 being provided with handle endoporus 4 in handle body 2 and communicating with handle endoporus 4, push rod 7 is provided with in handle endoporus 4, be provided with the screw rod 8 be connected with push rod 7 in screw 5, screw rod 8 one end is provided with interior cubic perforate 10, and interior cubic perforate 10 also can be interior six side's perforates.
Push rod 7 front end is taper thimble 9, and handle endoporus 4 diameter is not less than push rod 7 diameter, and handle endoporus 4 diameter is determined according to femoral stem model.
Screw 5 and screw rod 8 diameter match, and screw 5 and screw rod 8 diameter are determined according to femoral stem model.
Its principle is screw rod 8 screw forward, and make taper thimble 9 back down 120 ° of three opening button, 3,120 ° of three opening button 3 and open to three directions, 90 ° of teeth 6 are fixed on bone hole inwall, prevent femoral stem from gliding.
During use, first select the femoral stem model inserting bone hole smoothly, be contained in by push rod 7 in handle endoporus 4, screw rod 8 is contained in screw 5.During operation, hold femoral stem upper end 1, after femoral stem being inserted into bone hole to optimum position, with cubic perforate 10 in interior four square head wrench rotary screw 8 one end, make screw rod 8 head on push rod 7 and travel forward, when the taper thimble 9 of push rod 7 front end moves to button 3 front end, the taper thimble 9 of push rod 7 front end 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 end will be fixed on bone hole inwall, prevent the downslide of femoral stem.
The present invention's resected femur handle that expands solves existing femoral stem and easily occurs loosening in operation or spalling brings troublesome problem to operation, and structural design is simple, and simple operation, performs the operation more smooth, can improve success rate of operation, thus more be suitable for practicality.
