Abstract
The utility model relates to a disposable puncture needle for thyroid gland radiography, which comprises a needle core, a needle core body which is provided with a casing tube which is inosculate with the needle core body and enters a thyroid gland tissue after needle core puncture. After successful puncture, the needle core is extracted, the casing tube is remained in the thyroid gland tissue, the body surface of the needle core body is easy to fix, and the casing tube section in the thyroid gland tissue is relatively stable to avoid damage to the thyroid gland tissue and adjacent organs; simultaneously, casing tube nonvisulization under X-ray avoids image overlap interference to images caused by an original steel needle, and diagnosis accuracy rate is raised.
Description
This utility model relates to a kind of medical apparatus and instruments with the Thyreoidine radiography, particularly a kind of disposable thyroid radiography puncture needle.
The thyroid radiography is the important inspection method of diagnosis thyroid disease, still there is not at present special-purpose thyroid radiography puncture needle clinically, what use is the injection needle of using always (draw point), exist with topic and mainly contain two: the one, draw point is difficult to fix, and puncture back operator or patient's relative motion all can be damaged parathyroid tissue and adjacent organs; The 2nd, the not saturating X ray of draw point, syringe needle image and contrastographic picture are overlapping when film making, influence accuracy rate of diagnosis.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of improved disposable thyroid radiography puncture needle is provided, and it can avoid the damage to parathyroid tissue and adjacent organs, and noiseless to contrastographic picture.
The purpose of this utility model realizes by following technical proposals:
Disposable thyroid radiography puncture needle has nook closing member, its technical scheme be described nook closing member body be equipped with match with it with the sleeve pipe that enters after the nook closing member puncture in the parathyroid tissue.After so conventional thyroid body surface point of puncture sterilization, use disposable thyroid radiography puncture needle, after puncture puts in place, extract nook closing member, sleeve pipe is detained in the parathyroid tissue, and body surface is fixed, and connects syringe and injects contrast agent.Dynamic observe the development situation of contrast agent in parathyroid tissue, take the X ray sheet as required.
The diameter of nook closing member and its site of puncture of sleeve pipe is respectively 0.75～0.80mm and 0.80～0.85mm in the technique scheme.At nook closing member and telescopic site of puncture casing wall thickness is 0.2mm.
This utility model since described nook closing member body be equipped with match with it with the sleeve pipe that enters after the nook closing member puncture in the parathyroid tissue, therefore, extract nook closing member after waiting to puncture successfully, in sleeve pipe (plastic flexible pipe) parathyroid tissue of being detained, body surface is easy to fix, relatively stable at the parathyroid tissue inner sleeve, avoided damage to parathyroid tissue and adjacent organs; Simultaneously sleeve pipe does not develop under X ray, has avoided the interference of the former image overlap that causes with draw point to image, can improve accuracy rate of diagnosis greatly.
This utility model is described in further detail below in conjunction with embodiment:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of nook closing member in this utility model.
Fig. 3 is the structural representation of this utility model middle sleeve.
As Fig. 1, Fig. 2, shown in Figure 3, the utlity model has nook closing member 1, sleeve pipe 2.Nook closing member 1 upper end has handle, and its lower end is the site of puncture of nook closing member, and the diameter at this position is 0.79mm.Nook closing member 1 body be equipped with match with it with the sleeve pipe 2 that enters after the nook closing member puncture in the parathyroid tissue.Sleeve pipe 2 is a plastic flexible pipe.The diameter of sleeve pipe site of puncture is 0.81mm, and the wall thickness of sleeve pipe at this position is 0.20mm.
Claims (3)
1, a kind of disposable thyroid radiography puncture needle has nook closing member, it is characterized in that described nook closing member (1) body be equipped with match with it with the sleeve pipe (2) that enters after the nook closing member puncture in the parathyroid tissue.
2, disposable thyroid radiography puncture needle according to claim 1 is characterized in that the above-mentioned nook closing member (1) and the diameter of its site of puncture of sleeve pipe (2) are respectively 0.75～0.80mm and 0.80～0,85mm.
3, disposable thyroid radiography puncture needle according to claim 1 and 2 is characterized in that site of puncture sleeve pipe (2) wall thickness at nook closing member (1) and sleeve pipe (2) is 0.2mm.
