The utility model provides a needle body development of pjncture needle is not outstanding among the prior art, and the needle point can't distinguish with the needle body, and the puncture accuracy is low, the puncture degree of difficulty and risky technical problem.

Description

Ultrasonic puncture needle

Technical Field

The utility model relates to the field of medical equipment, more specifically relates to an ultrasonic puncture needle.

Background

Interventional ultrasound refers to a technique for accurately inserting a puncture needle or a catheter into various organs or tissues in a human body under real-time ultrasound image monitoring, and performing various diagnoses and treatments such as puncture and fluid extraction, histological biopsy, catheterization and drainage, tumor ablation or pain treatment, and is widely applied to clinics and provides pathological bases for clinical diagnosis. Most puncture needle surfaces on the existing market are smooth, ultrasonic waves are projected on the surfaces of the puncture needles to be specular reflection, the number of formed sound beams is small, if the angle formed by the needle inserting direction of the puncture needle is small, the needle body is more difficult to develop, a clinician can often cause the puncture direction and the puncture distance of the puncture needle to be incapable of determining, the needle point development is not prominent, the needle body can not be distinguished from the needle body, the needle point can not be accurately observed, the target position needs to be determined repeatedly, the puncture accuracy is reduced, and the difficulty and the risk of puncture are increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that the needle body of the puncture needle in the prior art is developed and is not outstanding, the needle point can not be distinguished from the needle body, the puncture accuracy is low, and the puncture difficulty is high and risky.

In order to solve the problems, the ultrasonic puncture needle comprises a needle point, a needle body and a needle seat which are fixedly connected in sequence; the surface of the needle body is provided with a plurality of arc-shaped scale grooves; the scale groove is vertical to the axis of the needle body; the side surface and the bottom of the scale groove are subjected to frosting treatment; the inner side surface of the needle tip is frosted.

In particular, the length of the scale groove is 1/2 or 1/3 of the circumference of the needle body.

In particular, the width of the scale groove is 1 mm.

In particular, the interval between every two scale grooves is 1 cm.

Particularly, the inclined plane of the needle point and the axial line of the needle body form an included angle of 15-18 degrees.

Particularly, the groove edge of the scale groove is an arc edge.

The utility model has the advantages that:

the utility model has the advantages that the surface of the needle body is provided with a plurality of scale grooves, the side surfaces and the bottom parts of the scale grooves are processed by grinding, and diffuse reflection generated by grinding can facilitate ultrasonic development and ensure the puncture direction and puncture distance of the puncture needle for the clinician; the length of the scale groove is 1/2 or 1/3 of the circumference of the needle body, so that the resistance and the astringent feeling during puncture can be reduced to the maximum extent; the inner side surface of the inner side of the needle point is frosted, the needle point can also be subjected to ultrasonic development, the target position can be confirmed more easily, the puncture accuracy and safety are enhanced, and the puncture difficulty and risk are reduced.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic overall structure diagram of an embodiment of the present invention;

in the figure: 1. a needle tip; 2. a needle body; 3. a needle seat; 4. a scale groove.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

As shown in fig. 1, the ultrasonic puncture needle of the present embodiment includes a needle tip 1, a needle body 2 and a needle holder 3 which are fixedly connected in sequence. The surface of the needle body 2 is provided with a plurality of arc-shaped scale grooves 4. The scale groove 4 is vertical to the axis of the needle body 2. The side and bottom of the scale groove 4 are frosted. The groove edge of the scale groove 4 is an arc edge. The inner side surface of the needle point 1 is frosted, so that a clinician can find the needle point 1 conveniently. The length of the scale groove 4 is 1/2 or 1/3 of the circumference of the needle body 2. The width of the scale groove 4 is 1 mm. The interval between every two scale grooves 4 is 1 cm. The inclined plane of the needle point 1 and the axis of the needle body 2 form an included angle of 15-18 degrees. The inclined plane of the needle point 1 and the axial line of the needle body 2 form a smaller included angle, thus being beneficial to puncture and improving the smoothness of the puncture process.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, various changes and modifications can be made by the owner within the scope of the appended claims, and the protection scope of the present invention should not be exceeded by the claims.
