Abstract
The invention discloses a kind of unidirectional spicules, helicla flute is offered in one end of needle body, the top at helicla flute is opened up and is equipped with protrusion, it is one that the thread groove of end, which is only separately provided, to prevent from excessively leading to spicule end strength reduction because of screw thread, it is broken during spicule pierces.In addition, the thread groove is one-directional rotation design so that the spicule may only single direction rotation, and be unable to bidirectional rotation.The front end of protrusion is equipped with blade, and blade is in cusped edge shape.Blade is in cusped edge shape, can play the role of positioning, prevent spicule during piercing from slipping when contacting periosteum.Needle body is cylindrical body, and diameter range is 0.5 to 7.0mm.The utility model has the advantages that design is reasonable, structure is simple, easy to use, only unidirectional rotatable helicla flute has been opened up in the end of needle body, the case where thoroughly having prevented spicule and hollow nail mutually locking and having deepened continuously, it is entirely avoided other organs are deeply damaged due to spicule.
Description
Technical field
The present invention relates to a kind of spicule, in particular to a kind of unidirectional spicule.
Background technique
Spicule is surgical instrument important in bone surgery, at present clinically common spicule typically refer to steinman pin and gram
Family name's needle.Both spicules, can bidirectional rotation inserting needle, specifically pierce in bone during, can be clockwise or inverse with electric drill
Clockwise rotates inserting needle.It is easy to produce many clinical complications in this way.
Fritz Steinmann has invented steinman pin (Steinmann pins) in 1907, and diameter is 3.5 to 6.0mm
Between.Steinman pin needs the laggard needle that first drills, since the loosening of needle will lead to the generation of infection.In addition, steinman pin is mostly homalocephalus,
Heat production is more when piercing, and is affected to knitting.
On this basis, 1909, Martin Kirschner invented thinner Kirschner wire (Kirschner
Wires), for diameter 0.7 between 1.5mm, being not required to drill in advance, needle fixation is more stable, and infection occurs few.Kirschner wire is mostly point
Head, heat production is few when piercing, and influences on knitting smaller.
Kirschner wire biggest advantage is that atraumatic is percutaneously inserted into.This technology is easier than open reduction and interior fixation,
Relevant risk is smaller, swelling and stiff minimum.But the intensity of Kirschner wire is weaker and can not position, and displacement frequent occurrence, can
It can lead to fatal complication.In the cases of most of reports, spicule from shoulder belt be transferred to aorta, heart, lung, tracheae,
Mediastinum, neck, spleen and canalis spinalis.Also there is the report migrated from other regions of anatomy, such as from buttocks to chest, heart, liver
The migration of Huo popliteal nest, or even enter heart from left hand.
Summary of the invention
The purpose of the present invention is to solve existing spicule in use existing problems and provide one
The unidirectional spicule of kind.
Unidirectional spicule provided by the invention offers helicla flute in one end of needle body, opens up the top at helicla flute equipped with convex
It rises, it is one that the thread groove of end, which is only separately provided, to prevent from excessively leading to spicule end strength reduction because of screw thread, is bored in spicule
It is broken during entering.In addition, the thread groove is one-directional rotation design so that the spicule may only single direction rotation, and cannot
Bidirectional rotation.
The front end of protrusion is equipped with blade, and blade is in cusped edge shape.Blade is in cusped edge shape, can play the role of positioning, prevent from boring
Spicule is slipped when contacting periosteum during entering.
Needle body is cylindrical body, and diameter range is 0.5 to 7.0mm.
The working principle of the invention:
Unidirectional spicule provided by the invention divides clockwise direction spicule and inverse time direction spicule.In fracture site operation,
It such as uses counter clockwise direction spicule as guide pin, can only counterclockwise pierce the needle, i.e., it clockwise can not be into
Needle, at this moment further along the spicule clockwise pierce hollow screw group, if during hollow nail pierces, have small bone block or
Soft tissue enters the gap of spicule and hollow nail, causes mutually locking between the two, unidirectional spicule end provided by the invention
The helicla flute opened up is merely able to one-directionally rotate, and will not rotate together with the hollow nail that opposite direction rotates, then hollow nail can not
Continue to pierce, and then also prevent continuing deeper into for spicule, avoids the damage of other organs.
And commonly spicule, can be with Double-directional rotary, if there is the mutually interlocking between spicule and hollow nail without this special designing
It is fixed, it is possible that the case where spicule and hollow nail pierce together, causes accidental injury.
Beneficial effects of the present invention:
Unidirectional spicule design provided by the invention is reasonable, structure is simple, easy to use, has opened up only in the end of needle body
The helicla flute of one-directional rotation avoids completely the case where thoroughly having prevented spicule and hollow nail mutually locking and deepened continuously
Other organs are deeply damaged due to spicule.

Specific embodiment
Shown in please referring to Fig.1 to Fig.4:
Embodiment one:
Unidirectional spicule provided by the invention offers helicla flute 2 in one end of needle body 1, opens up the top at helicla flute 2 and sets
There is protrusion 3, it is one that the thread groove 2 of end, which is only separately provided, to prevent from excessively leading to spicule end strength reduction because of screw thread,
Spicule is broken during piercing.In addition, the thread groove 2 is to rotate clockwise design, so that the spicule may only unidirectionally revolve
Turn, and is unable to bidirectional rotation.
The front end of protrusion 3 is equipped with blade, and blade is in cusped edge shape.Blade is in cusped edge shape, can play the role of positioning, prevent from boring
Spicule is slipped when contacting periosteum during entering.
Needle body 1 is cylindrical body, and diameter range is 0.5 to 7.0mm.

Unidirectional spicule provided by the invention offers helicla flute 2 in one end of needle body 1, opens up the top at helicla flute 2 and sets
There is protrusion 3, it is one that the thread groove 2 of end, which is only separately provided, to prevent from excessively leading to spicule end strength reduction because of screw thread,
Spicule is broken during piercing.In addition, the thread groove 2 is to rotate counterclockwise design, so that the spicule may only unidirectionally revolve
Turn, and is unable to bidirectional rotation.
The front end of protrusion 3 is equipped with blade, and blade is in cusped edge shape.Blade is in cusped edge shape, can play the role of positioning, prevent from boring
Spicule is slipped when contacting periosteum during entering.
Needle body 1 is cylindrical body, and diameter range is 0.5 to 7.0mm.
The working principle of the invention:
Unidirectional spicule provided by the invention divides clockwise direction spicule and inverse time direction spicule.In fracture site operation,
It such as uses counter clockwise direction spicule as guide pin, can only counterclockwise pierce the needle, i.e., it clockwise can not be into
Needle, at this moment further along the spicule clockwise pierce hollow screw group, if during hollow nail pierces, have small bone block or
Soft tissue enters the gap of spicule and hollow nail, causes mutually locking between the two, unidirectional spicule end provided by the invention
The helicla flute 2 opened up is merely able to one-directionally rotate, and will not rotate together with the hollow nail that opposite direction rotates, then hollow nail can not
Continue to pierce, and then also prevent continuing deeper into for spicule, avoids the damage of other organs.
And commonly spicule, can be with Double-directional rotary, if there is the mutually interlocking between spicule and hollow nail without this special designing
It is fixed, it is possible that the case where spicule and hollow nail pierce together, causes accidental injury.
