Abstract
The utility model relates to a puncture needle for interventional therapy, which belongs to the field of medical appliance and is arranged for a guiding tube pin used to introduce a guiding wire, comprises a needle tube with needle point and a needle stand, and is characterized in that the needle stand is a hollow body, one end of the needle stand is closely fastened at the end of the needle tube opposite to the needle point, and the connection of the internal surfaces of the needle stand and the needle tube is level, smooth and fluent. For the technical solution is adopted, the puncture needle of the utility model can be operated by a doctor more easily.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of puncture needle that is used for interventional therapy.
Background technology
In the treatment of cardiovascular disease, usually use the interventional therapy method.Treatment like this often needs regular ground constantly some insertings or liquid to be transported in the patient body.Such interventional therapy method is to puncture on blood vessel by puncture needle, after introducing catheter sheath in the blood vessel, puncture needle is extracted, and catheter sheath is stayed in the blood vessel, place the metal guide seal wire by catheter sheath, by the guiding of metal guide seal wire, need are stayed the support that is used for the treatment of in the patient body put into blood vessel then.Present puncture needle manufacturing is all too simple, and needle stand is too smooth, is unfavorable for that the doctor uses.The design of puncture needle the inside very the more important is the needle stand part, and the cooperation of it and needle tubing should not have step, and very smooth and easy when catheter sheath is entered from the needle stand of puncture needle tail end, nothing is blocked.And the inner surface of the needle stand of the present puncture needle that is used for interventional therapy and needle tubing connection has step, and is smooth and easy inadequately when catheter sheath enters puncture needle.
Summary of the invention
The purpose of this utility model is to provide the puncture needle that is easy to be used for more smoothly when doctor's operation can make catheter sheath enter puncture needle again interventional therapy that burr is arranged on a kind of needle stand.
The technical scheme that realizes this utility model purpose is: a kind of puncture needle that is used for interventional therapy, be matched in catheter sheath, comprise the needle tubing and the needle stand that have needle point, wherein, above-mentioned needle stand is a hollow body, this needle stand one end is fastened on a needle tubing end relative with needle point, being connected to being connected of smooth smooth smoothness of the inner surface of above-mentioned needle stand and above-mentioned needle tubing inner surface.
Above-mentioned needle stand and the outer surface of needle tubing coupling part are provided with the striped parallel with the needle tubing axis of protrusion.Above-mentioned needle stand is the hollow body of PC material.Above-mentioned needle tubing diameter is greater than the diameter of catheter sheath, and above-mentioned needle tubing diameter is the 1.2-2 millimeter.
Owing to adopted above-mentioned technical solution, solved the too slick problem of present puncture needle needle stand fully, more smooth and easy when making catheter sheath enter puncture needle.Puncture needle of the present utility model is easier to doctor's operation.
Description of drawings
Fig. 1 is used for the sketch map of the puncture needle of interventional therapy for this utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments:
Referring to Fig. 1, a kind of puncture needle that is used for interventional therapy, comprise the needle tubing 2 and the needle stand 3 that have needle point 1, wherein, above-mentioned needle tubing 2 diameters are greater than the diameter of guiding wire, above-mentioned needle tubing diameter is 1.5 millimeters, above-mentioned needle stand 3 is the hollow body of PC material, these needle stand 3 one ends are fastened on the relative end of needle tubing 2 and needle point 1, the smooth smooth smoothness in the junction of the inner surface of above-mentioned needle stand and above-mentioned needle tubing inner surface, this junction inner surface does not have step, can allow catheter sheath enter in the puncture needle and can not run into step, and is more smooth and easy when entering.
Above-mentioned needle stand 3 and the outer surface of needle tubing 2 coupling parts are provided with the striped 4 parallel with needle tubing 2 axis of protrusion.
Above embodiment is only for the usefulness of explanation this utility model, but not to the restriction of this utility model protection domain.The designer in relevant present technique field; under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion or modification, and the technical scheme that all are equal to should belong to also within the category of this utility model protection, is limited by appended claim.
