Description
Technical field
It the utility model is related to a kind of neck of femur and put nail servicing unit, belong to technical field of medical instruments.
Background technology
In the internal fixation operation of fracture of neck of femur or intertrochanter fracture of femur, one or more screw is required for effectively
Insert in neck of femur, except ensureing ideal position of the screw in the projection of neck of femur normotopia, also to take into account in neck of femur lateral projection
On position.Neck of femur has 15 degree of top rake, therefore, this require bore nail take into full account the top rake of neck of femur because
Element, keep suitable guid needle inserting needle forward leaning angle.Existing servicing unit is difficult to reliably preset forward leaning angle, is more
By clinical experience and feel, but whether its forward leaning angle properly needs to have an X-rayed after piercing to judge, is needed if perspective is improper
Readjust drilling forward leaning angle.Correction drilling repeatedly both extends operating time, increases neck of femur destruction of bone again, increases day
The probability of caput femoris necrosis afterwards, nail is put when serious and loosens, fail.
The content of the invention
Goal of the invention of the present utility model is to provide one kind can easily make a reservation for properly drill to lean forward when neck of femur puts nail
Angle, avoid drilling blindness and reduce fault rate, raising puts nail one-time success rate, shortens the servicing unit of operating time.For
Solution above-mentioned technical problem, the utility model proposes technical scheme be：A kind of neck of femur puts nail servicing unit, including positioning
Indicator and working tube；The positioning indicator is made up of needle body and hollow backshank；The hollow cavity of the backshank it is transversal
Face semicircular in shape, perpendicular to the planar side of the backshank hollow cavity, its tail end is fixedly connected in the backshank needle body
Corresponding to the semicircle side of empty inner chamber on lateral wall, the working tube is by through the semi-cylindrical connecting rod of the backshank and fixation
It is connected to the conduit part composition of described connecting rod one end, planar side of the conduit part perpendicular to the connecting rod；The needle body
Parallel with the conduit part, the connecting rod can be slided in the backshank.
Neck of femur provided by the utility model puts nail servicing unit simple structure, and easy to use, operation is easy to grasp, can be
Easily make a reservation for suitable drilling forward leaning angle when neck of femur puts nail, avoid drilling blindness, nail one-time success rate is put in raising, is contracted
Short operating time, reduce the pain and medical treatment cost of patient.

Embodiment
Embodiment
The utility model is to be achieved through the following technical solutions goal of the invention：As shown in figure 1, neck of femur puts nail servicing unit
Overall to be combined into by positioning indicator 1 and the both parts of working tube 2, positioning indicator 1 includes needle body 3 and backshank 4 two
Point, working tube 2 is made up of the semi-cylindrical connecting rod 6 through backshank 4 with the conduit part 5 for being fixedly connected on the one end of connecting rod 6.
Such as Fig. 2, the cross section semicircular in shape of the hollow cavity of backshank 4, plane of the needle body 3 perpendicular to the hollow cavity of backshank 4
Side, the tail end of needle body 3 are fixedly connected on corresponding to the semicircle side of the hollow cavity of backshank 4 on lateral wall.
Such as Fig. 3, planar side of the conduit part 5 perpendicular to connecting rod 6；So, after positioning indicator 1 and the assembling of working tube 2,
Needle body 3 is parallel with conduit part 5, and connecting rod 6 can be slided in backshank.
As shown in figure 4, the semicircle inner chamber of backshank 4 of the insertion positioning indicator 1 of connecting rod 6 of working tube 2, is combined into femur
Neck puts nail servicing unit entirety, and the semi-cylindrical form of connecting rod 6 matches completely with the semicircle inner chamber of backshank 4, by gram of conduit part 5
Family name's pin 7 (or drill bit) is natural parallel to needle body 3, insertion depth i.e. adjustable needle body 3 and conduit of the adjustment connecting rod 6 in backshank 4
The spacing in portion 5.
Needle body 3 is long 10cm, diameter 2.5mm stainless pins in the present embodiment, and backshank 4 is that long 1.5cm, external diameter 10mm are hollow
Stainless steel tube, steel pipe intracavity section are diameter 8mm semicircle, and needle body 3 is welded in the tube wall of backshank 4, and pad is away from pipe wherein one end
0.5cm.Conduit part 5 is 5cm length, external diameter 4mm, internal diameter 2.5mm stainless steel tubes (caliber can use different size as needed), is connected
Extension bar 6 is 6cm length, cross-sectional diameter 8mm semi-cylindrical stainless steel bars, and conduit part 5 is protected connecting rod and is welded and fixed.In the present embodiment
Connecting rod 6 can be adjusted freely in the insertion depth of backshank 4 in 0.5cm-6cm scopes.In neck of femur neck, basal part and tuberosity
Between this region bone face of front side it is relatively flat, an approximate plane, with human coronary face angulation close to anteversion of femoral neck, it is parallel should
Plane drilling can obtain appropriate forward leaning angle.When needle body 3 is close to this region bone face, conduit part 5 and through conduit part
Kirschner wire 7 (or drill bit) be also just approximately parallel to the bone face.During operation, after completing the reduction of the fracture, needle body 3 is close to bone face and put
In front of neck of femur, perspective is determined with after the suitable angulation of femoral shaft, holding indicator 1, and connecting rod 6 is inserted instruction backshank 4,
Boring point can arbitrarily be selected as needed by adjusting the insertion depth of connecting rod 6 and being rotated with needle body 3 for axle, Kirschner wire 7 (or bore
Head) pierced through conduit part 5 can obtain normotopia projection and the relatively satisfactory drilling of forward leaning angle, reduce drilling fault rate.
