Description
Technical field
The present invention relates to medical instrument field, more particularly to a kind of easy entry spicule.
Background technology
Metal bone needle is a kind of internal fixation device for treating fracture, and spicule is made of metal material, mainly pure titanium,
Titanium alloy, cobalt-base alloys and stainless steel etc..Metal and Alloy material, there is sufficiently large intensity and toughness, counter-bending and anti-torsion
Ability is strong, belongs to bio-inert material, and the combination of bone is a kind of mechanical sealed.
Since existing metal bone needle is relatively fine, but when squeezing into spicule, generally require to cut a very big wound, create
Mouth is bigger, is difficult to recover in the later stage, it is now desired to a product, more easy and convenient when spicule is put into injury, energy
Enough realize minimally invasive.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of easy entry spicule, caused by the prior art above-mentioned to solve
Multinomial defect.
To achieve the above object, the present invention provides following technical solution：A kind of easy entry spicule, including principalia and spicule
Set, the principalia top are divided into cylindrical worm, and lower part is divided into conical drill bit, and the spicule set is interior symmetrical sliding equipped with two
Groove, is fixed with limiting plate and push rod in the sliding slot, and the push rod passes through limiting plate, baffle is fixed with the push rod,
Resetting spring is equipped between the baffle and limiting plate, the lower end of the push rod is equipped with box of returning sword, the lateral wall of the box of returning sword
Knife straight slot is equipped with out, T-shaped cutting blade is equipped with the box of returning sword and releases spring, the T-shaped cutting blade passes through out knife
Straight slot.
Preferably, the cylindrical bar and drill bit are integrally formed.
Preferably, the screw thread on the cylindrical worm is trapezoidal thread.
Preferably, the inner wall lower end of the spicule set is equipped with inclination angle of returning sword.
Preferably, the lower end of the box of returning sword is equipped with bottom knife.
It is using the beneficial effect of above technical scheme：A kind of easy entry spicule of the present invention, when beginning to use, Ke Yi
One osculum of injury external-open, principalia is wrapped in spicule set, allows spicule set to go out to slowly move through skin from osculum with principalia
Skin and muscle, at this moment, can down promote push rod, and the push rod box that will return sword is released from sliding slot, and such cutting blade is releasing bullet
It under the action of spring, can be hit by a bullet out from knife straight slot is gone out, be organized so as to down cut in flesh all the way, reduce the resistance that spicule enters,
Reach predetermined position with spicule, afterwards, unclamp push rod, resetting spring can up push and block plate, so as to drive push rod and box of returning sword
Up move, and cutting blade can be by inclination angle of returning sword toward contract, then spicule set taken out from wound, pass through cylinder snail
Bar drives whole spicule to rotate, and is fixed with principalia, and principalia is conveniently pierced by drill bit.
