Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of gate nail for Cruciate ligament reconstruction be oriented to and
Impactor.
Background technology
Gate nail used in Sport Medicine is used primarily in front and rear Cruciate ligament reconstruction, for the tendon after implantation
It is reinforced, squeezes into the method for gate nail at present mainly using electric drill, with Kirschner wire jewel hole, followed closely with vessel forceps clamping gate,
Then two pinpricks that gate nail alignment is allowed to drill out, hammer are directly squeezed into, this method shortcoming：1st, since Most patients are all
Young man, sclerotin is harder, when tapping gate nail, should not once squeeze into, need to beat observation repeatedly, waste the plenty of time,
And gate nail is easily tapped deformation or even sometimes plays gate nail and flies out.2nd, the front and rear friendship that Sport Medicine is done
Fork ligament reconstructive operation belongs to Minimally Invasive Surgery, and notch is smaller, two anchor point phases for conveniently squeezing into gate nail that electric drill drills out
The smaller for so should not observe, wastes the plenty of time for looking for anchor point, increases operating time sometimes.3rd, gate
Nail squeezes into certain depth and passes through tendon, and the bad grasp of this depth is too deep to be pulled through tendon, excessively shallow easily to follow closely gate
It trains off.
Invention content
It is an object of the invention to propose that a kind of gate nail for Cruciate ligament reconstruction is oriented to and impactor, solution are existing
Gate nail easily taps the problem of deformation, location difficulty and driving depth are difficult to determine existing for technology.
To achieve the above object, a kind of gate nail for Cruciate ligament reconstruction of the invention is oriented to and impactor includes determining
Position shell and the percussion bar for being arranged on relative positioning shell slip inside positioning shell；
Through-hole A is provided with along axis among the positioning shell, the end cap of through-hole B is carried centered on positioning shell one end, it is described logical
Hole A is connected with through-hole B, is symmetrical arranged about through-hole B that there are two pilot hole A on the end cap, and the positioning shell is far from end cap one
Gate slot, the gate slot and gate to be squeezed into nail clearance fit are provided on the side wall at end, and is connected with through-hole A, it is described
It is the arcuate structure being recessed inwardly to position four side wall ends of the shell far from end cap one end；
The bar that taps includes the body of rod and is fixed on the striking head of body of rod one end, on the striking head side wall along its length
Pilot hole A corresponding positions are provided with arc groove, the striking head lower end and gate to be squeezed into nail on end face cooperation,
The striking head and through-hole A cooperations, the percussion bar and through-hole B cooperations.
The percussion bar further includes percussion disk, and the disk that taps is connected with the end thread of body of rod stretching positioning shell one end,
On the percussion disk and pilot hole A corresponding positions are provided with pilot hole B.
The pilot hole A and pilot hole B allows Kirschner wire to pass through.
The diameter of the arc groove is identical with the diameter of pilot hole A and pilot hole B.
The through-hole A being provided among the positioning shell include two sections, one section be square hole, another section be round hole, the side
Striking head clearance fit on shape hole and percussion bar, and connected with the gate slot, the round hole and the bar for tapping bar
Body space coordinates, and is connected with the through-hole B on end cap.
Beneficial effects of the present invention are：A kind of gate nail guiding and impactor for Cruciate ligament reconstruction of the present invention
It is the arcuate structure being recessed inwardly to position four side wall ends of the shell close to gate slot one end, four angles is made to form tip, favorably
In positioning, while arcuate structure is conducive to be pulled through the tendon to be positioned in position fixing process, while facilitates look at beating for gate nail
Enter depth, in use, being positioned by positioning shell, Kirschner wire passes through pilot hole to realize jewel hole, pulls upwardly on percussion bar, passes through gate
Gate nail is put into square hole by slot, is unclamped and is tapped bar, taps the striking head of bar lower end and gate nails on end face contact, pass through
The percussion disk for beaing percussion bar one end squeezes into gate nail, and whole process is once completed, and a large amount of operating times is saved, due to entire
Percussion process gate follows closely always portion in the device, so being not in deformation, beating winged situation；Gate nail needs to fix before being put into
Tendon move scheduled position to by positioning the arcuate structure of shell lower end, can be directly placed into gate nail beat, will not
Too deep excessively shallow situation is beaten in appearance.
