Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a visual arc-blade needle for ultrasound-guided puncture. Background Technology

[0002] The existing ultrasonic-guided puncture needle includes a needle hub and a needle body fixed to the needle hub and extending in the front-back direction. The end of the needle body away from the needle hub is the needle tip. An ultrasonic reflective texture structure or ultrasonic reflective coating is provided on the outer periphery of the needle body for use with an ultrasonic probe.

[0003] When in use, the operator holds the needle holder to manipulate the needle body. The needle tip punctures the skin. The ultrasonic reflective texture structure or ultrasonic reflective coating, in conjunction with the ultrasonic probe, can reflect ultrasonic waves, increasing the reflection in the ultrasonic image, making it easier for the operator to clearly observe the position and direction of the needle body.

[0004] However, the existing ultrasound-guided puncture needle has the following problem: the needle tip is a simple bevel structure, which results in low release efficiency during soft tissue release treatment and cannot achieve the therapeutic effect of an arc-blade needle. Utility Model Content

[0005] The purpose of this invention is to provide a visual arc-blade needle for ultrasound-guided puncture that uses an arc-blade needle tip structure to facilitate soft tissue release operations.

[0006] To solve the above-mentioned technical problems, the technical solution of the ultrasound-guided puncture visual arc-blade needle of this utility model is as follows:

[0007] An ultrasound-guided puncture visual arc-blade needle includes a needle base, on which a needle body extending in the front-back direction is fixed. The needle body is hollow, and the end of the needle body away from the needle base has a needle tip structure. The outer periphery of the needle body is provided with a needle body ultrasonic reflective texture structure or a needle body ultrasonic reflective coating for use with an ultrasound probe. The needle tip structure includes a first needle tip bevel and a second needle tip bevel spaced apart front to back. The angle between the first needle tip bevel and the needle body axis is greater than the angle between the second needle tip bevel and the needle body axis. The rear end of the first needle tip bevel and the front end of the second needle tip bevel are connected by a straight transition section. The surfaces of the first needle tip bevel, the transition section, and the second needle tip bevel are coated with a needle tip ultrasonic reflective coating.

[0008] Furthermore, the needle tip ultrasonic reflective coating is a nano-needle tip ultrasonic reflective coating formed by nano-spraying.

[0009] Furthermore, the length of the transition section is 2~14mm.

[0010] Furthermore, the angle between the second needle tip bevel and the needle body axis is between 15° and 40°; the angle between the second needle tip bevel and the needle body axis is between 20° and 45°.

[0011] Furthermore, the needle body is provided with puncture depth markers spaced at intervals along the anterior-posterior direction.

[0012] Furthermore, an ultrasonic reflective coating is applied to the puncture depth mark on the needle body.

[0013] The beneficial effects of this invention are as follows: In this invention, an ultrasonic reflective texture structure or ultrasonic reflective coating for use with an ultrasonic probe is provided on the outer periphery of the needle body. The first needle tip bevel, the transition section, and the second needle tip bevel are coated with an ultrasonic reflective coating. Therefore, during the overall puncture process of the needle body, the position of the needle body and the needle tip structure can be clearly known with the help of an ultrasonic probe. In this invention, the angle between the first needle tip bevel and the needle body axis is greater than the angle between the second needle tip bevel and the needle body axis. Therefore, the needle tip structure adopts an arc-blade needle structure. With the help of an ultrasonic probe, the position of each needle tip bevel in the body can be clearly seen, which is very convenient for soft tissue release operations. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] An embodiment of this utility model of a visual arc-blade needle for ultrasound-guided puncture is shown below. Figures 1-3 As shown:

[0022] It includes a needle holder 1, on which a needle body 2 extending in the front-to-back direction is fixed. The needle holder 1 is located at the rear end of the needle body. The needle body 2 is a hollow structure. The end of the needle body away from the needle holder, i.e. the front end of the needle body, has a needle tip structure 4. An ultrasonic reflective coating (or ultrasonic reflective texture structure) is provided on the outer periphery of the needle body for use with an ultrasonic probe.

[0023] In this utility model, puncture depth markers 3 are arranged at intervals along the front-to-back direction around the outer periphery of the needle. In this embodiment, there are two sets of puncture depth markers, arranged sequentially front to back. Each set of puncture depth markers includes three annular marker units arranged at intervals along the front-to-back direction around the outer periphery of the needle. Within the same set of puncture depth markers, the number of rings in each annular marker unit is different. For example, from front to back, the number of rings in the three annular marker units are one, two, and three, respectively. An ultrasonic reflective coating is applied to the corresponding annular markers. That is to say, in this embodiment, the ultrasonic reflective coating can not only work with the ultrasonic probe to display the position of the needle within the skin, but also provide the operator with an intuitive visual judgment of the puncture depth.

[0024] The needle tip structure includes a first needle tip bevel 5 and a second needle tip bevel 7 spaced apart. The angle between the first needle tip bevel 5 and the needle body axis is greater than the angle between the second needle tip bevel and the needle body axis. The rear end of the first needle tip bevel 5 and the front end of the second needle tip bevel 7 are connected by a straight transition section 6, which is half the length of the complete needle body. The surfaces of the first needle tip bevel 5, the transition section 6, and the second needle tip bevel 7 are coated with a needle tip ultrasonic reflection coating. Figure 2 From a visual perspective, the second needle tip bevel is V-shaped, while the first needle tip bevel is arc-shaped. Therefore, the puncture needle in this invention can be called a visible arc-blade needle.

[0025] In this embodiment, the ultrasonic reflective coating on the needle body is a nano-needle tip ultrasonic reflective coating formed by nano-spraying; the length of the transition section is 5 mm; the angle between the second needle tip bevel and the needle body axis is 20°; the angle between the second needle tip bevel and the needle body axis is 25°. In other embodiments of this utility model, the length of the transition section can also be 2 mm, 14 mm, or other values ​​between 2 and 14 mm; the angle between the second needle tip bevel and the needle body axis can also be 15°, 40°, or other values ​​between 15° and 40°; the angle between the second needle tip bevel and the needle body axis can also be 20°, 45°, or other values ​​between 20° and 45°.

[0026] Before using the ultrasound-guided puncture-guided curved-blade needle, the doctor first conducts a comprehensive examination of the patient to determine the lesion location. Then, the ultrasound equipment is turned on, the ultrasound probe is coated with coupling gel and fixed to the skin surface of the patient's treatment site to obtain a clear ultrasound image. The doctor holds the ultrasound-guided curved-blade needle and, based on the ultrasound image, adjusts the needle position and angle, slowly advancing the needle until the needle tip reaches the lesion site to perform the corresponding treatment. During the treatment, the doctor continuously observes the ultrasound image to ensure safety and effectiveness. The combination of ultrasound and the curved-blade needle effectively addresses the shortcomings of existing ultrasound puncture needles in soft tissue release treatment and has broad market application prospects. The hollow needle body allows for injection, aspiration, and other treatment operations at the patient's site.
