Abstract
The invention discloses a proximal femur intramedullary nail ring guide apparatus. The proximal femur intramedullary nail ring guide apparatus comprises a contractile ring, wherein the ring is composed of a section of circular ring which is not closed, and a hollow guide pipe is welded to one side of the ring. The proximal femur intramedullary nail ring guide apparatus is simple in structure; when femoral shaft fracture surgery and femoral intertrochanteric fracture surgery are performed, a medical worker stretches a finger into the ring at a surgical incision and takes out the finger after the device is placed in the surgical incision, an intramedullary nail is hit inwards from the hollow guide pipe, and therefore the aim of rapidly and accurately selecting and positioning the proximal femur inlet point is achieved, workloads of the medical worker are reduced, and the proximal femur intramedullary nail ring guide apparatus is worthy of wide popularization.
Description
Technical field
The present invention relates to bone surgery equipment, particularly relate to a kind of PFN ring guider.
Background technology
In recent years, because the improvement of internal fixation device, the raising of surgical technic and people are to the change of fractures idea, fracture of shaft of femur now more is tending towards operative treatment.Fracture operation is treated, except must from fracture position, type, soft tissue injury degree, injure outside the factor considerations such as the systemic conditions of patient with or without merging, also need to select according to two principles: one is the internal fixation material that will have sufficient intensity, make fixing after can early functional exercise and internal fixation apparatus fracture and inefficacy occur before being unlikely to union of fracture; Two is that fracture fixation method will advocate Wicresoft, reduces the destruction of fracture local blood fortune and the internal fixation apparatus stress that do not have as far as possible and concentrates and meet biological fixation principle, to promote union of fracture.
Need patient visit with finger and enter to follow closely position and determine entry point in current femoral surgery, but owing to existing the factor such as entry point is dark, surrounding soft tissue's stop, cause operation technique difficulty to increase.
Summary of the invention
The object of the invention is to, overcome the above-mentioned defect of prior art, a kind of PFN ring guider is provided.
For achieving the above object, technical scheme provided by the invention is as follows: a kind of PFN ring guider, comprise a contractile ring circle, described ring circle is made up of one section of inc annulus, and ring circle side is welded with the guide pipe of one section of hollow.
Wherein, the pilot hole diameter of hollow guide pipe is 3.5 millimeters.
Wherein, ring circle and guide pipe are stainless steel.
Usefulness of the present invention is, structure is simple, easy to operate, because of the scalability of ring circle, can adapt to different finger sizes, greatly reduce the operation easier in operation, reduce the workload of medical personnel.
Accompanying drawing explanation
Fig. 1 is the ring circle schematic diagram of PFN ring guider of the present invention.
Fig. 2 is the axonometric chart of PFN ring guider of the present invention.
Detailed description of the invention
Be further described with regard to technical scheme of the present invention below in conjunction with accompanying drawing and preferred embodiment.
As shown in Figure 1 and Figure 2, a kind of PFN ring guider of the present invention, comprise a contractile ring circle 1, ring circle 1 is made up of one section of inc annulus, and ring circle 1 side is provided with the guide pipe 2 of one section of hollow.
Further, the pilot hole diameter of guide pipe 2 is 3.5 millimeters.
Further, ring circle 1 and guide pipe 2 are stainless steel.
Further, when carrying out fracture of shaft of femur, femoral intertrochanteric fracture with operation, finger is inserted in ring circle 1 at operative incision place by medical personnel, after putting into operative incision, finger is taken out, and is squeezed in patient body by intramedullary pin by pilot hole 3 at the guide pipe 2 from hollow.
Above-described is only principle of the present invention and preferred embodiment.It should be pointed out that to those skilled in the art, under the premise without departing from the principles of the invention, some modification and improvement can also be made, also should be considered as belonging to protection scope of the present invention.
Claims (3)
1. a PFN ring guider, comprise a contractile ring circle, it is characterized in that: described ring circle is made up of one section of inc annulus, ring circle side is welded with the guide pipe of one section of hollow.
2. a kind of near end of thighbone ring guider according to claim 1, is characterized in that: the pilot hole diameter of described hollow guide pipe is 3.5 millimeters.
