Description
Technical field
The present invention relates to the technical field of attachment structure after fractured near end of thighbone, particularly a kind of telescopic near end of thighbone connects
Connection device.
Background technology
Fractured near end of thighbone includes fracture of neck of femur, intertrochanteric fracture and fracture of neck of femur and merges femoral trochanter
Between fracture three types.It is common classification of fracture in elderly population.Led for the patient without absolute surgical contraindication at present more
Open operative treatment.Fracture of neck of femur refers to be broken between femoral head and femur, needs to be integrated with mode connects for screw after fracture.China
The U of patent publication No. CN 202477828 disclose fractured near end of thighbone nail-stick system, including screw rod, and screw head has nail tip,
Screw front end surface is provided with nail tip screw thread, and screw rod end surface is provided with nail tail screw thread, and the end of screw rod is additionally provided with spherical
Nail tail, nail tail on be provided with it is spherical nail tail in six side's screw channels.Nail tail is arranged in the nut of U shapes and with being set in nut
The surface of spiral shell wedge fits.
The nail-stick system is connected as one femoral head, neck of femur and femur by two main screws being parallel to each other, and two
Main screw is separate, and after pole comes off, two main screws are also easily exited, and there is the insecure defect of connection.This
Femoral head, neck of femur and femur can only be connected as one by planting nail-stick system, can not be by this if being broken on femur
Nail-stick system is attached, using being limited in scope.For different age group patient, the femur length of human body is to differ
, inserted by using the single main barred body of length value in femoral bone cavitas medullaris to carry out near end of thighbone connection, although stock can be connected
The fracture of bone, but the main barred body that manufacture different length needs, using 20 ~ 40 moulds, so to increase the production costs of mould
With.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art there is provided a kind of compact conformation, can connect femoral head with
Crack can connect faulted joint on femur, suitable for different age group patient, the telescopic femur being connected firmly again between femur
Near-end attachment means.
The purpose of the present invention is achieved through the following technical solutions：A kind of telescopic near end of thighbone attachment means, it includes
Main barred body, the first screw, the second screw, secondary screw and cylinder, the proximal end of the main barred body offer the first inclined hole and second
Inclined hole, the lower section of the first inclined hole of the second inclined hole position and connect with the first inclined hole, and inclined hole axis and main barred body are described in angle setting
The first screw set through the first inclined hole, the second screw is through the setting of the second inclined hole, the screw thread of the second screw and the first screw
Screw thread be meshed, the far-end of the main barred body, which is installed with threaded rod, described cylinder, offers internal thread, and cylinder is through interior
Screw thread is connected and fixed on threaded rod with threaded rod, and running through on the cylinder of cylinder has secondary screw.
Described secondary screw is horizontally disposed with.
The length of the first described screw is more than the length of the second screw.
The present invention has advantages below：Compact conformation of the present invention, crack can be connected between femoral head and femur and can be connected
Connect the faulted joint on femur, suitable for different age group patient, be connected firmly.
Brief description of the drawings
Fig. 1 is structural representation of the invention
Fig. 2 is operating diagram of the invention；
Fig. 3 is Fig. 1 A-A sectional views；
In figure, the main barred bodies of 1-, the screws of 2- first, the screws of 3- second, 4- screw, the inclined holes of 5- first, the inclined holes of 6- second, 7-
Body, 8- threaded rods, 9- femorals head and femur faulted joint, 10- femur faulted joints.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in Fig. 1 ~ 3, a kind of telescopic near end of thighbone attachment means, it include main barred body 1, the first screw 2, the second screw 3,
Secondary screw 4 and cylinder 7, the proximal end of the main barred body 1 offer the first inclined hole 5 and the second inclined hole 6, the second inclined hole 6 first
The lower section of inclined hole 5 and connected with the first inclined hole 5, inclined hole axis is with main barred body 1 in angle setting, and the first described screw 2 runs through
First inclined hole 5 is set, and the second screw 3 is set through the second inclined hole 6, and the length of the first screw 2 is more than the length of the second screw 3,
The screw thread of second screw 3 is meshed with the screw thread of the first screw 2 to be formed joint self-locking nail and combines, and improves stability, and anti-rotation is prevented
Cut out and produce significant pressure effect when being screwed into pressurization nail.As shown in Fig. 1 ~ 3, the far-end of the main barred body 1 is installed with screw thread
Internal thread is offered in bar 8, described cylinder 7, cylinder 7 is connected and fixed on threaded rod 8 through internal thread and threaded rod 8, therefore
It can increase or reduce the total length of the attachment means by turning cylinder 7, to adapt to the length of different age group patient femur,
Different moulds need not be manufactured, cost is reduced.Through there is secondary screw 4 on the cylinder of described cylinder 7, secondary screw 4 is horizontally disposed with.
The course of work of the present invention is as follows：The total length of patient with operation femur is treated in measurement, and rotary barrel 7 makes the bottom of cylinder 7
End face is less than femur length away from main barred body 1 apart from sum；Cylinder 7 is inserted in femoral bone cavitas medullaris from top to bottom, it is ensured that cylinder 7
Through femur faulted joint 10, the first screw 2 is then run through into femur and is inserted in the first inclined hole 5, its end of thread is passed through into stock
Bone and femur faulted joint 10 are simultaneously screwed into femoral head, and the second screw 3 then is run through into femur and is inserted in the second inclined hole 6,
And its end of thread is passed through into femoral head and femur faulted joint 10 and is screwed into femoral head, while ensureing the first screw 2 and the second spiral shell
Nail 3 constitutes joint self-locking nail, finally by secondary screw 4 sequentially through femur and cylinder 7 to realize the fixation of main barred body 1, therefore not
Only realize and femoral head is connected firmly with femur, realize again and connect femur breaking part, application more will be wide, and connection
Firmly.
Described above is only the preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
Form, is not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and environment, and can be at this
In the text contemplated scope, it is modified by the technology or knowledge of above-mentioned teaching or association area.And those skilled in the art are entered
Capable change and change does not depart from the spirit and scope of the present invention, then all should appended claims of the present invention protection domain
It is interior.
