Description
Technical field
The present invention relates to a kind of the field of medical instrument technology, more particularly to a kind of modified form pulmonary nodule Needle localization needle guard
Part.
Background technology
Small pulmonary nodule refers to the similar round lesion of intrapulmonary isolatism, and diameter is less than 2cm, no pneumonia drawn game portion lymph node
Increase.In recent years, the patient of Small pulmonary nodule is more and more, and the early diagnosis of Lung neoplasm is more difficult, clinically lacks special
Property shows form of diverse in iconography, good, pernicious to be not easy to conclude, often results in mistaken diagnosis and delays treatment.Clinically such is suffered from
Person advocates surgical operation therapy, obtains preferable effect.In surgical procedures, mostly uses small pulmonary artery under thoracoscope and cut off
Art accurately positions the position of lesser tubercle, often becomes the key of operation success or failure, therefore the lower localised puncture of preoperative CT guiding is very
It is important.
Preoperative fine needle puncture small pulmonary artery location technology under CT guiding in recent years, in the operation of thoracoscope lower lung eminectomy
Carry out extensively.Currently, the puncture localization needle used in clinically, in actual use, the breathing and activity of adjoint patient,
Pilot pin is easily displaced, falls off, in the preoperative or in art into wall of the chest musculature, or even slides into and indulge in diaphragm, so as to cause
Operating time extends, and resection range is excessive, or even opens the case where chest looks for pilot pin and happen occasionally, and is caused to patient unnecessary
Injury.
For this purpose, applicant carried out beneficial exploration and trials, it was found that a kind of modified form lung nodules Needle localization needle guard
Part scheme, technical solution described below generate in this background.
Invention content
Technical problem to be solved by the present invention lies in carried for the deficiency present in existing Lung neoplasm positioning puncture needle
For a kind of modified form lung nodules puncture needle external member, positioning guide wire is improved so that be not easy after positioning guide wire positioning lesion
It migration and falls off.
The technical problems to be solved by the invention can be achieved through the following technical solutions：
A kind of modified form Lung neoplasm puncture needle external member, including one with endoporus puncture needle and in the puncture needle
The positioning end of the positioning guide wire in hole, the positioning guide wire is provided with V-arrangement barb, that one end at positioning guide wire relative positioning end
For promote-side, the position of positioning end is provided with strengthening portion in the positioning guide wire, which is characterized in that in the positioning guide wire
The position of positioning end is provided with a bending section with memory function, the bending section is described in positioning guide wire insertion
It is deformed when in the endoporus of puncture needle linearly, bending is reverted to again after the endoporus that the positioning guide wire leaves the puncture needle
Shape.
In a preferred embodiment of the invention, spire setting the V-arrangement barb and the strengthening portion it
Between.
In a preferred embodiment of the invention, the bending section is helical form.
In a preferred embodiment of the invention, the helical form is made of a spiral.
In a preferred embodiment of the invention, further include a positioning guide wire clamp, when the V-arrangement barb of positioning guide wire is caught on
After lesion, the positioning guide wire clamp is stuck in the position that the positioning guide wire exposes skin surface.
As a result of technical solution as above, the present invention catches on lesion simultaneously by the V-arrangement barb of positioning guide wire positioning end
After extracting puncture needle, the V-arrangement barb on positioning guide wire cooperates with bending section, and positioning guide wire is prevented forwardly and rearwardly to swim
It walks, will not fall off with lesion.In addition the present invention fixes positioning guide wire, also by increasing a positioning guide wire clamp into one
Step has prevented positioning guide wire and has been detached from the lesion retraction wall of the chest or slides into the possibility for indulging diaphragm, prevents out the embarrassment that chest looks for pilot pin, keeps away
Exempt from resulting complication.

Fig. 2 is the positioning guide wire structural schematic diagram in modified form Lung neoplasm puncture needle external member of the present invention.
Fig. 3 is the combination after positioning guide wire positioning with positioning guide wire clamp in modified form Lung neoplasm puncture needle external member of the present invention
Status diagram.
Specific implementation mode
Referring to Fig. 1 and Fig. 2, a kind of modified form Lung neoplasm puncture needle external member provided in figure, including wearing with endoporus
The tail portion of pricker 10 and positioning guide wire 20, puncture needle 10 is fixed on a puncture needle base portion 30.Before use, positioning guide wire 20 is by wearing
This one end of pricker base portion 30 is inserted into the endoporus of puncture needle 10.There is positioning guide wire 20 positioning end 21 and one to push end 22,
After positioning guide wire 20 is inserted by this one end of puncture needle base portion 30 in the endoporus of puncture needle 10, the positioning end of positioning guide wire 20 21
In the endoporus of puncture needle 10, puncture needle base portion 30 is exposed at push end 22, in order to be pierced into lesion in the needle point 11 of puncture needle 10
Afterwards, it is positioned to intralesional push positioning guide wire 20.
The positioning end 21 of positioning guide wire 20 is provided with V-arrangement barb 23, in positioning guide wire 20 close to the position of positioning end 21
It is provided with strengthening portion 24.
First feature of the present invention is that the position of positioning end 21 is provided with one in positioning guide wire 20 to have memory work(
The bending section 25 of energy, bending section 25 are arranged between V-arrangement barb 23 and strengthening portion 24.
In the shape of a spiral, helical form is made of a bigger spiral of diameter, is also not excluded for remaining certainly for the bending section 25
The receptible curved shape of institute in other lesion localizations and surgical procedure.Puncture needle 10 is inserted into bending section 25 in positioning guide wire 20
It is deformed when in endoporus linearly, curved shape is reverted to again after the endoporus that positioning guide wire leaves puncture needle 10.Pass through positioning
The V-arrangement barb 23 of 20 positioning end 21 of seal wire catches on lesion and after extracting puncture needle 10, the V-arrangement barb 23 on positioning guide wire 20 with
Bending section 25 cooperates, and prevents positioning guide wire 20 from forwardly and rearwardly removing, will not fall off with lesion.
The present invention second feature be further include a positioning guide wire clamp 40, when positioning guide wire 20 V-arrangement barb 23 hook
Firmly after lesion, positioning guide wire clamp 40 is stuck in the position that positioning guide wire 10 exposes appearance skin, has further prevented positioning guide wire
The retraction wall of the chest or the possibility for sliding into other positions of thoracic cavity.
