Description
Technical field
The present invention relates to technical field of medical instrument, and in particular to a kind of femur punching locating guider.
Background technique
Femur is located at thigh center, since leg muscle tissue is abundant, when percutaneously setting nail punching to femur, is extremely difficult to
Femoral shaft center, when punching, are often amesiality, influence surgical effect, postoperative complications easily occur, as nail is fixed
Insecure, femur aligns not good enough etc. to line.The prior art is the sleeve that there is dentation in a distal end, is percutaneously inserted into up to femoral shaft,
Flat doctors experience and feel sleeve position come determine punching position.The disadvantage is that: 1, sleeve cannot be accurately positioned and be located at stock
Backbone center；2, hub distal end has detent projection, during reaching femoral shaft into muscle, detent projection muscle injury tissue,
It is wound when rotating simultaneously with meat fiber tissue, brings additional damage to patient.
In conclusion the present invention devises a kind of femur punching locating guider.
Summary of the invention
In view of the shortcomings of the prior art, object of the present invention is to be to provide a kind of femur punching locating guider,
Femoral shaft central location can be accurately positioned, reduce operation wound, improve surgical result.
To achieve the goals above, the present invention is to realize by the following technical solutions: femur punches locating guider,
Including three parts, first part is sleeve, second part is sleeve inner core, and Part III is " 5 " font metal strip inner core, institute
The sleeve stated includes that cylindrical tube, cross section are rectangle pipeline, the first in command, and cylindrical tube two sides are symmetrically arranged with cross
Section is rectangle pipeline, the first in command of ellipse is provided with above cylindrical tube, the cylindrical tube bottom is
Concave up arc-shaped structure, concave up arc-shaped structure two sides are provided with triangular hill, triangular hill upper and lower two
The angle α and β of side and cylindrical tube point is 30 ° and 60 °, and cross section is rectangle pipe end and terminates in above triangular hill
Setting, and cross section is rectangle pipeline lateral wall and extends downwardly and outwardly setting, and longitudinal sectional with highest point on the outside of triangular hill
Concordantly；The sleeve inner core includes cylindrical sleeve inner core, second handle, cylindrical sleeve inner core and cylindrical tube grafting
Cooperation, cylindrical sleeve inner core upper end are connect with second handle, and cylindrical sleeve inner core bottom is coniform；Described " 5 " word
Shape metal strip inner core tail end section is in oblique under, and distal end angle γ is 30 °, and " 5 " font metal strip inner core is plugged on cross
Section is rectangle in pipeline.
Preferably, the first in command and second handle are the ellipse metal plate of stainless steel.
Preferably, the cylindrical tube diameter is greater than the diameter of cylindrical sleeve inner core, cylindrical sleeve inner core
Length is greater than the length of cylindrical tube.
Preferably, described " 5 " font has the thickness and width of memory and flexible metal strip inner core to be less than cross
Section is rectangle the thickness and width of pipeline.
Beneficial effects of the present invention: guider sleeve (first part) of the invention and sleeve inner core (second part) assembling
Afterwards, distally in tip and smooth, when merging reaches femoral shaft can voluntarily reaming, be easily placed in, and be blunt separation, will not be right
Musculature causes the additional damages such as cutting, winding.First part's remote design is arc-shaped at what is concaved, increases and stock
Contact area and docile degree when backbone contacts improve degree of stability when femur dry contact, extract after arriving at femoral shaft
Second part, first part distal end and femoral shaft voluntarily pairing, do not need to rotate, manual adjustment pairing saves surgical procedure
Time reduces simultaneously and operation wound.Slot trace interpolation with cylinder two sides enters two " 5 " font metal strip (third portions
Point), card is embraced femoral shaft by Part III distal end, since Part III two cards embrace the length angle symmetrical of femoral shaft, by the
The cylinder of a part is voluntarily adjusted to the center of femoral shaft, and the guiding and positioning function of guider are completed since then.
