Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of segment type fine steel needle.
Background technology
Bone traction is directly to draw bone by fine steel needle so that fracture, dislocation patient carry out effectively reset and
It is fixed, it is frequently utilized for skin injury, serious swelling, infected wound or bone and crushes seriously go the patient of interior fixation.Bone is led
Draw pin is generally made up of medical metal material.After fine steel needle is inserted, both sides need to expose for use in connection trailer system.But by
There is tip in fine steel needle, if occur to touch by mistake, touching object is easily damaged.Therefore, Chinese patent " disposable fine steel needle
Protective case " (notification number：CN204092143U, the day for announcing：2015-01-14) propose the rubber stopper for fine steel needle tip
Formula protection structure.Simultaneously as needing frequently to adjust traction dynamics during Bone traction, sliding axially for fine steel needle is easily caused
(unexpected touching is also possible to cause to slide), causes suffering to patient, easily triggers the physics of contact position (Bone traction needle track)
Property or pathogenicity inflammation, therefore, Chinese patent " slide-proof bone tracting needle " (notification number：CN201692030U, the day for announcing：2011-
01-05) proposing surface has the fine steel needle of anti-slip veins.
But, because fine steel needle is all integral structure, causes during protection structure is installed, adjust trailer system
During and in the case of occurring unexpected touching, for caused by the fine steel needle effect in direction such as axially and radially
The vibration of fine steel needle, swing or bounce can be directly delivered to by its end in needle track mouthful and needle track, and anti-slip veins are consolidated
It is set for using, can not be also unfavorable for suppressing these motions of fine steel needle simultaneously (although the fixation of anti-slip veins can be effective
Anti- sliding stop), as a result, being exactly to cause the higher incidence of Bone traction needle track inflammation.
The content of the invention
The purpose of this utility model is to provide a kind of segment type fine steel needle.
To reach above-mentioned purpose, the utility model employs following technical scheme：
Including hollow barred body and it is arranged on the tail end barred body and needle point body at hollow barred body two ends, the needle point body and sets
Have and be provided with anti-slip veins on demountable end face protective case, the external wall of hollow bar, tail end barred body and needle point body are respectively with setting
The vibration damping connector being placed in hollow bar body is connected.
The hollow barred body, tail end barred body and needle point body are made of medical metal material.
The vibration damping connector is made of damping material.
The vibration damping connector is made of elastomeric material.
The vibration damping connector can be slided with respect to wall in hollow bar body.
Demountable end face protective case is provided with the tail end barred body.
The beneficial effects of the utility model are embodied in：
Hollow barred body, tail end barred body and needle point body are combined as three segmentals using vibration damping connector and led by the utility model
Draw pin, is set by merogenesis, can segment the function of the different sections of fine steel needle, and pin is formed using hollow barred body as human body is inserted
The part in road, with tail end barred body and the extraneous draw applied of needle point body connection, three are both connected to by vibration damping connector
Individual section, has played vibration damping, cushioning effect again, so as in the case where ensureing the normal use of fine steel needle, effectively reduce
Bone traction pin site infection, improves the therapeutic efficiency of Bone traction, and alleviates the pain of patient.

Embodiment
The utility model is elaborated with reference to the accompanying drawings and examples.
Referring to Fig. 1, Fig. 2 and Fig. 5, segment type fine steel needle described in the utility model by existing integral type titanium alloy (or
Other optional metal materials) fine steel needle is decomposed into three sections (leading portion, stage casing and endpieces)；Leading portion is included after needle point and needle point
Face is used for connect trailer system 7 one section；Stage casing is hollow-core construction, when fine steel needle inserts human body, stage casing hollow-core construction outer wall
Contacted with needle track, needle track is stretched out at two ends；The section that endpiece is used to connect trailer system 7 for another.Also for protection doctor
Life, families of patients etc. may contact people or the article of fine steel needle, and needle point and endpiece are provided with the bigger guarantor of end face diameter
Sheath 6, the protective case 6 is typically made of elastomeric material or plastics, be expert at fine steel needle implantation when need to pull out, drew
Then put in journey.Also for fine steel needle sliding axially in needle track is prevented, such as due to installing during above-mentioned protective case 6
Caused fine steel needle is slid axially, and anti-slip veins 5 are provided with the outer wall of stage casing hollow-core construction.
Referring to Fig. 3 and Fig. 4, the above-mentioned fine steel needle for being decomposed into three sections is attached, connector 4 can by connector 4
To be arranged at the column construction being made up of damping material in the hollow-core construction of stage casing one of in the form of using, it is hollow with stage casing
Inner structural wall is interference fit, and its outer end is fixedly connected with leading portion and endpiece, and gap is left between three sections of fine steel needle, from
And when vibration is transferred to column construction by leading portion and endpiece, dissipation vibrational energy, reduction or elimination vibration are transferred to stage casing
Possibility.Certainly, under this form, the quantity of connector 4 can be one, or two.The shape that connector 4 can be used
The two of formula are similarly column construction, and quantity is two, and material is preferable and with certain support strength for the elasticity such as rubber
Material, such column construction is located in the hollow-core construction two ends of stage casing respectively, and is fixedly connected respectively with leading portion and endpiece, this shape
Column construction under formula can be slided relative to stage casing hollow-core construction inwall.So, be expert at fine steel needle implantation when, can first allow
Three sections of fine steel needle close contacts, conveniently take the needle and smoothly form needle track, then, by by leading portion and the outside layback of endpiece
Go out, column construction is outwards synchronously stretched out certain length, finally, can select trailer system 7 being connected to according to actual conditions
The reserved location (Fig. 5) of leading portion and back segment, or the section for selecting the column construction that trailer system 7 is connected into both sides to expose
On, slow down swing or the active force transmitted to needle track of beating so as to realize.
Clinical test shows, by above segment type fine steel needle, can effectively reduce Bone traction pin site infection, improve
The therapeutic efficiency of Bone traction.
