Abstract

The utility model discloses a bronchocele puncture therapeutic needle comprising a needle core (1), a sleeve (2) and an extracting cylinder (3). The needle core (1) is arranged in the sleeve (2), the extracting cylinder (3) is connected with the needle core (1), the front end of the sleeve (2) is provided with a air chamber (4), the front opening fringe of the sleeve (2) is provided with a circular edge fringe (5), besides that the front end of the needle core (1) is provided with a central liquid extraction hole (6), the walls of the needle core (1) are symmetrically provided with two to four liquid extraction side holes (7). During the cyst fluid extraction, the sleeve of the needle core of the bronchocele puncture therapeutic needle will not fall off, during the injection of the medication, the injected medication is less, thereby, avoiding the side effects arising from overdose and improving the therapeutic effect.

Description

Thyroid cyst puncture for treating pin

Technical field

This utility model relates to the cyst medical apparatus and instruments, particularly a kind of thyroid cyst puncture for treating pin.

Background technology

Thyroid cyst is a kind of subcutaneous cyst, and the most effective Therapeutic Method is: at first penetrate in the thyroid cyst with puncture needle, the CF body is extracted out, and then inject the anhydrous alcohol medicine in capsule.Simple extraction CF body, only play a part to alleviate intrinsic pressure, no therapeutic effect, only after exhausting the CF body, reinject anhydrous alcohol or other some medicines make blister cavities intine-held protein qualitative change matter, destroy blister cavities inwall body of gland, closed blister cavities just can reach therapeutic purposes.At present used puncture needle is by nook closing member, sleeve and take out tube and constitute, nook closing member is enclosed within carries out drawing liquid in the sleeve, after exhausting the CF body, nook closing member is extracted, sleeve is stayed in the blister cavities, the reuse syringe injects medicine in blister cavities in sleeve, its weak point is: in extracting capsule liquid process out, because the CF body reduces gradually, cyst wall retraction, sleeve pressurized and withdraw from blister cavities automatically causes medicine can not be injected in the blister cavities, if be injected into outside the capsule, will cause normal organ tissue degeneration, necrosis; The 2nd, because blister cavities is bigger, it is more to inject medicine, causes the waste of medicine on the one hand, and too much on the other hand drug absorption also causes side effect easily; The 3rd, because the nook closing member head end has only a drawing liquid hole, laminated diaphragm is arranged if meet in the capsule, also can influence drawing liquid and therapeutic effect.

Summary of the invention

The purpose of this utility model is to provide a kind of and can stops syringe needle to deviate from blister cavities in extracting capsule liquid process, if meeting barrier film also can take out most capsule liquid, and can control the thyroid cyst puncture for treating pin of medicine injection rate.

For reaching above purpose, the technical scheme that this utility model adopted is: this thyroid cyst puncture for treating pin, by nook closing member, sleeve, take out the tube constitute, nook closing member is sleeved in the sleeve, take out tube and be connected, be provided with gas cell, be provided with annulus sword edge on sleeve prosopyle edge at telescopic leading section with nook closing member, the nook closing member front end is except that having drawing liquid hole, center, also establish symmetric 2-4 drawing liquid side opening on wall, set gas cell can have two effects, and the one, prevent that nook closing member from deviating from, the 2nd, fill blister cavities, reduce the medicine injection rate; The doing of the annulus sword edge on sleeve prosopyle edge when meeting barrier film in the blister cavities, taken out a piston by pulling the time spent, and barrier film can suck in the drawing liquid side opening, the pulling nook closing member, and barrier film can be by the annulus sword along cutting, and drawing liquid no longer is subjected to membranous the influence; This utility model is also implemented by following measure: described sleeve can be rubber tube and makes, and the annulus sword is along being embedded in the telescopic mouthful of edge, and the gas tube of gas cell is entered by the upper end, establishes through hole in the sleeve lower end, and the outer end connects inflatable ball.When using this utility model, at first nook closing member is thrust in the blister cavities under the B ultrasonic guiding together with sleeve, a piston is taken out in pulling, the CF body is extracted out, if meet barrier film, after barrier film sucks the drawing liquid side opening, the nook closing member of pulling back, telescopic annulus sword can continue drawing liquid, in drawing liquid along cutting barrier film, in gas cell, inflate, gas cell props up blister cavities, prevents that on the one hand sleeve from deviating from, and gas cell has occupied the most of space of blister cavities on the other hand, pull up nook closing member, be connected with the injection drug syringe again, in blister cavities, inject anhydrous alcohol or sclerosis medicine again, reach therapeutic purposes.

The beneficial effects of the utility model are: in taking out capsule liquid process, the nook closing member sleeve can not deviate from, and when injectable drug was treated, injectable drug was few, has avoided the chance that has side effects because of dose is excessive, has improved therapeutic effect.
