In addition, most existing puncture needles are smooth or have one-way concave reflective pits on the surface, resulting in poor ultrasonic reflection. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The purpose of this invention is to provide an ultrasonic imaging puncture needle to solve the problems existing in related technologies and improve the imaging effect of the puncture needle under ultrasound.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, this embodiment provides an ultrasound imaging puncture needle, including a needle tube 1, through which a hole 101 is passed, and one end of the needle tube 1 is a puncture end 102. The needle tube 1 is preferably a stainless steel needle tube. A reflective ring is provided on the outer wall of the needle tube 1 near the puncture end 102. The reflective ring is a structure formed by multiple sets of reflective grooves 2 evenly arranged along the circumference of the needle tube 1. Each set of reflective grooves 2 is a structure formed by two triangular pyramidal pits 201 facing each other and three reflective surfaces are formed in each triangular pyramidal pit 201.

[0025] Specifically, such as Figure 2 As shown, each triangular pyramidal recess 201 includes three reflective surfaces, which form an arrow-shaped concave triangle, and all three reflective surfaces are inclined toward the bottom of the triangular pyramidal recess 201; the two triangular pyramidal recesses 201 in each set of reflective grooves 2 are distributed adjacently and the arrows point in opposite directions.

[0026] In this embodiment, as Figure 3 As shown, there are 8 reflective rings, all of which are arranged along the axial direction of the needle tube 1 (i.e., Figure 3 The needles are evenly arranged in the left and right directions to form a reflective zone on the outer wall of the needle tube 1.

[0027] Furthermore, an enhanced developing layer 3 is provided in the reflective zone area of ​​the needle tube 1 to enhance the developing effect.

[0028] As a possible example, the enhanced imaging layer 3 is coated on the reflective zone area of ​​the needle tube 1. The enhanced imaging layer 3 is a resin coating. Specifically, the resin coating is preferably a resin coating containing active carboxyl groups. The coating is composed of isocyanate, resin containing active carboxyl groups, foam stabilizer and other components in a certain proportion. Carbon dioxide gas is generated by the reaction of the resin containing active carboxyl groups and isocyanate, which forms multiple microbubbles with a diameter of 1μm-50μm inside the coating. This forms a solid-gas discontinuous interface on the outer surface of the needle tube 1, which can change the angle and direction of ultrasonic reflection and generate more diffuse reflection on the reflective surface of the reflective groove 2, thereby achieving enhanced imaging.

[0029] As another possible example, the enhancing imaging layer 3 is electroplated on the reflective zone area of ​​the needle tube 1. The enhancing imaging layer 3 is a tungsten alloy coating. Since the tungsten alloy coating has high hardness and density, when ultrasound enters the tungsten alloy coating from human soft tissue, the tungsten alloy coating and the surrounding medium have a large difference in acoustic impedance. According to the acoustic principle, the greater the difference in acoustic impedance, the more ultrasound energy is reflected. Therefore, the tungsten alloy coating can exhibit a strong ultrasound reflection capability.

[0030] In summary, the ultrasound imaging puncture needle provided in this embodiment forms a reflective groove 2 with two opposing triangular pyramidal pits 201, forms a reflective ring with multiple sets of reflective grooves 2 arranged in a circular pattern, forms a reflective zone area with multiple reflective rings arranged in a linear pattern, and has an enhanced imaging layer 3 attached to the surface of the reflective zone area, which further enhances the ultrasound signal reflection of the puncture needle and enhances the visibility of the puncture needle.

[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
