Abstract

The utility model relates to a proximal bone nail end reamer of interlocking femoral croos-medullary nail, which comprises a cutter, a sleeve barrel, and a spanner. One end of the cutter is a wring drill, and the other end is a quadrangular bar. The spanner comprises a movable rotation rob and a fixed bar, an assembly port is arranged on the fixed bar, and the movable rotation rob is connected with the assembly port of the fixed bar via threads. A V-shaped compact heap is connected on an internal extension end which penetrates into the assembly port, and the V-shaped compact heap is engaged with the outer sides of the quadrangular bar of the cutter. The end portion of the quadrangular bar of the cutter is positioned in the assembly port of the spanner fixed bar, the sleeve barrel takes on a shape of cylindrical pipe, and one orifice of the cylindrical pipe is connected with a handle. The utility model has the advantages of timesaving, laborsaving, and accurate positioning when the utility model is applied to operations.

Description

Femur intramedullary nail with lock proximal bone nail tail reamer
Technical field
This utility model relates to a kind of femur intramedullary nail with lock proximal bone nail tail reamer.
Background technology
The use of femur intramedullary nail with lock technology is extensive day by day, but last nail apparatus is still satisfied inadequately, also disunity, and nail tail reamer commonly used mostly is S shape prismatic or square, rely on the rotation of handle manpower to enlarge tail nail hole, time-consuming, effort, and uropore out-of-shape influence squeezing into of intramedullary pin, sometimes cause the duct deflection, intramedullary pin is malposition in medullary cavity, causes accurately para-position of fracture, and pinning is locked difficulty.
Summary of the invention
The purpose of this utility model provides a kind of femur intramedullary nail with lock proximal bone easy to use, accurate positioning and follows closely the tail reamer.
Concrete structural design scheme is as follows:
It comprises reamer, sleeve and spanner, and reamer one end bores for strand, and the other end is the quadrangular bar; Sleeve is a cylindrical tube, the one end mouth of pipe is connecting handle, spanner comprises movable swing arm and fixed bar, fixed bar is provided with installation opening, movable swing arm is threaded with the installation opening place of fixed bar, movable swing arm stretches on the interior inner extending end of installation opening and is connecting the V-arrangement compact heap, and the V-arrangement compact heap cooperates with the quadrangular bar lateral surface of reamer, and the quadrangular boom end of reamer is positioned at the installation opening of spanner fixed bar.
Save time when the beneficial effects of the utility model are to use, laborsaving and accurate positioning.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of reamer;
Fig. 4 is the structural representation of spanner;
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment:
Embodiment 1:
A kind of femur intramedullary nail with lock proximal bone nail tail reamer, it comprises reamer 1, sleeve and spanner, and reamer 1 one ends bore 2 for strand, and the other end is a quadrangular bar 3; Sleeve is a cylindrical tube, the one end mouth of pipe is connecting handle 5, spanner comprises movable swing arm 7 and fixed bar 6, fixed bar 6 is provided with installation opening 9, movable swing arm 7 is threaded with the installation opening place of fixed bar 6, movable swing arm 7 stretches on the interior inner extending end of installation opening and is connecting V-arrangement compact heap 8, and V-arrangement compact heap 8 cooperates with quadrangular bar 3 lateral surface of reamer 1, and quadrangular bar 3 ends of reamer 1 are positioned at the installation opening 9 of spanner fixed bar 6;
Quadrangular bar 3 with reamer 1 during use inserts in the installation opening 9, turn activity swing arm 7 makes compactor 8 and installation opening 9 hole walls that quadrangular bar 3 is fixedly clamped, again with jacket casing outside reamer 1, telescopic effect is to prevent that strand is around soft tissue, according to reverse guid needle guiding behind the nearly section expansion of the femur marrow, direct motion approaches near end of thighbone, holds spanner rotation and drives reamer and can use, and saves time during use, laborsaving and accurate positioning.
Another function of sleeve 4 is when assembling marrow nail with lock afterbody nut, can look at pilot nail tail nut down straight by sleeve 4, and is convenient and swift.
Embodiment 2:
Quadrangular bar 3 with reamer 1 during use inserts Vidacare corp, can utilize Vidacare corp turn reamer to use, and omits spanner, and other are with embodiment 1.
