Abstract
This utility model relates to a kind of Thyroid puncture needle, its structure comprises solid interior pin and hollow outer pin, be provided with for pin pedestal in gripping at the end of described interior pin, the end of described outer pin is provided with the outer pin pedestal for gripping, described interior pin penetrates from the core bore of described outer pin, and its front end passes the leading section of described outer pin; The front end of described interior pin is oblique cutting face, the syringe needle tapered off to a point, and the syringe needle outer peripheral face of described interior pin has some axial shallow slots.This utility model is made up of the outer pin interted together and interior pin.In use, by rotating interior pin, in relying on, pin needle shaft makes nodal cells loosen to the frictional force of shallow slot, can increase the amount of drawing materials, increase the positive rate detecting cell, facilitate drawing materials of next step.
Description
Technical field
This utility model relates to a kind of puncture needle, specifically a kind of Thyroid puncture needle.
Background technology
In the diagnosis and treatment process of thyroid nodule, topmost is exactly to the good pernicious discriminating of tuberosity, and this is by the prognosis of the selection and patient that directly affect therapeutic scheme.Application of high resolution ultrasonic examination, radioisotope scanning etc. can assist diagnosis tuberosity character at present, but the topmost means of the good Malignant Nodules of preoperative diagnosis are still Fine-needle Aspiration Cytology (FNA).
Whether successfully in FNA biopsy, the amount of drawing materials is how many is determine biopsy determiner with quality height of drawing materials.How application 22-27 fine needle syringe needle carries out puncture is now drawn materials, because fine needle nook closing member is hollow, therefore the phenomenon that throat histiocyte obstruction nook closing member even occurs the cell being likely mixed into throat tissue in piercing process causes biopsy failure; If thyroid nodule is comparatively hard in addition, the consequence that the amount of drawing materials is few, positive rates of biopsy is low also can be caused.
Utility model content
The purpose of this utility model is just to provide a kind of Thyroid puncture needle, to solve that the existing tuberosity pricking device amount of drawing materials is few, quality of drawing materials is low and to there is the problem of biopsy failure.
This utility model is achieved in that a kind of Thyroid puncture needle, comprise solid interior pin and hollow outer pin, be provided with for pin pedestal in gripping at the end of described interior pin, the end of described outer pin is provided with the outer pin pedestal for gripping, described interior pin penetrates from the core bore of described outer pin, and its front end passes the leading section of described outer pin; The front end of described interior pin is oblique cutting face, the syringe needle tapered off to a point, and the syringe needle outer peripheral face of described interior pin has some axial shallow slots.
Axial shallow slot on described interior pin syringe needle has 2-3, and described axial shallow slot is distributed on the outer peripheral face at described interior pin syringe needle position.
The front end of described outer pin is also oblique cutting face, and the angle of this oblique cutting face and axial line is greater than the described oblique cutting face of interior pin syringe needle and the angle of axial line.
The front end outer wall of described outer pin is provided with scale mark.
This utility model is made up of outer pin and the pin within it that interts.Wherein, the front end of interior pin is set to oblique cutting face, the syringe needle tapered off to a point, in convenient insertion thyroid nodule.On the outer peripheral face of interior pin syringe needle, several axial shallow slots uniform, effectively can increase the frictional force of syringe needle.The length of interior pin is greater than outer pin, and interior pin syringe needle from outer pin front end outwardly, makes interior pin syringe needle first arrive tuberosity place.In use, by rotating interior pin, relying on needle shaft to the frictional force of shallow slot, nodal cells to be loosened, can the amount of drawing materials be increased, increase the positive rate detecting cell.When drawing materials, extract interior pin, use syringe to be connected with outer pin, tuberosity inner cell extracts in the hollow of outer pin by operating syringe, then extracts syringe needle, aspirate is evenly applied to standby inspection on microscope slide.The scale mark observed on outer pin can determine puncture needle insertion depth and the amount of drawing materials.

In figure: 1, outer pin, 2, interior pin, 3, outer pin pedestal, 4, interior pin pedestal, 5, axial shallow slot, 6, scale mark.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, this utility model is made up of the outer pin 1 interted together and interior pin 2.
Being provided with in pin 1 outside can the hollow of accommodating interior pin 2, and the end of pin 1 is provided with for hand-held outer pin pedestal 3 outside.Interior pin 2 can intert in outer pin pedestal 3 and outer pin 1, is provided with for pin pedestal 4 in hand-held at the end of interior pin 2.Outer pin pedestal 3 and interior pin pedestal 4 can be made up of PVC material.
The length of interior pin 2 is greater than outer pin 1, interior pin 2 interts after outer pin 1, the front end of interior pin 2 by the front end from outer pin 1 outwardly, interior pin syringe needle should exceed outer pin syringe needle and be about 3mm, make the deep amount of interior pin 2 in tuberosity more, can the amount of drawing materials be increased, and interior pin is longer than outer pin and is made in piercing process, throat cell can not be mixed in outer pin hollow, can quality of drawing materials be improved.The front end of interior pin 2 and outer pin 1 all can be set to an oblique cutting face, the syringe needle tapered off to a point, convenient puncture.
The outer peripheral face at the syringe needle position of interior pin 2 is evenly equipped with 2-3 axial shallow slot 5.After interior pin syringe needle thrusts tuberosity, by rotating interior pin 2, the axial shallow slot 5 on interior pin syringe needle produces friction to the nodal cells of surrounding, nodal cells can be made to loosen, obviously can increase sampling amount, increase the positive rate detecting cell, facilitate drawing materials of next step.
Outside pin 1 is also provided with scale mark 6, is used in use observing the deep amount of puncture needle and the amount of drawing materials.
Base part can be held with hand-held, in order to avoid pollute puncture needle during operation.Using method: 1, determine nodule position, if desired localization by ultrasonic; 2, patient gets seat or dorsal position, exposes cervical region; 3, if necessary can lignocaine local anesthesia; 4, be placed in outer pin by pin in interior pin, hand-held puncture needle thrusts thyroid nodule.After outer pin needle point arrives tuberosity position, the outer pin of fixing puncture needle, in rotating, pin makes nodal cells loosen.5, extract interior pin, connect outer pin with syringe, aspirate syringe needle gently, eliminate negative pressure after finding that there is aspirate at once, extract outer pin.6, aspirate is evenly applied to standby inspection on microscope slide.
