Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a needle tube with an ultrasonic enhanced imaging function. Background Art
[0002] In clinical practice, puncture needles are often used to puncture patient tissues and perform treatment or auxiliary treatment methods such as nerve localization, stimulation or medication. In the past, ordinary injection needles and anesthesia needles were generally used for blind puncture, which was a great test of the doctor's skills and experience. If the puncture position was not selected properly, nerve damage might occur.
[0003] In recent years, with the development of medical technology, especially in the field of nerve localization, in order to avoid blind puncture and damage to nerves, hospitals often use ultrasound guidance to assist in puncture. This makes it easier to accurately locate and avoid nerve damage. After puncture, the distribution area of the drug can be seen, reducing the use of local anesthetics.
[0004] However, in most cases, ordinary needles are still used. When ordinary needles are used for puncture in conjunction with ultrasonic imaging technology, the human eye cannot observe the imaging position of the needle clearly because of its smooth surface and small ultrasonic reflection surface. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a needle tube with a reasonable structural design, which can increase the ultrasonic development area of the outer circumferential surface of the needle tube by opening a groove on the outer circumferential surface of the needle tube on the basis of the original development of the outer circumferential surface of the needle tube, so as to increase the recognition of the needle tube under the ultrasonic development state, so that the needle tube can be more clearly developed and easy to locate during the puncture process.
[0006] The technical problem to be solved by the utility model is achieved through the following technical scheme: a needle tube with an ultrasonic enhanced development function, one end of the needle tube is used to be fixedly connected to the needle seat and is set as a fixed connection end, and the other end is used to puncture human skin and is set as a puncture end, and a strong development part is set on the outer peripheral surface between the fixed connection end and the puncture end of the needle tube;
[0007] The strong developing part arranged on the outer peripheral surface of the needle tube makes the outer peripheral surface of the needle tube no longer form a complete circumferential surface.
[0008] Preferably, the strong developing section is a plurality of developing tanks arranged on the outer peripheral surface of the needle tube.
[0009] Preferably, each group of the developing tanks is composed of a plurality of developing grooves, and the bottom surfaces of the developing grooves form a developing concave surface for enhancing the ultrasonic development visibility.
[0010] Preferably, each of the developing grooves is composed of a straight developing concave surface and two inclined developing concave surfaces, the middle parts of the two inclined developing concave surfaces intersect with the middle parts of the straight developing concave surface, and the two inclined developing concave surfaces are symmetrically arranged on both sides of the straight developing concave surface, and the straight developing concave surface and the inclined developing concave surfaces make the bottom surface of the developing groove a symmetrical pattern.
[0011] Preferably, the angle between the straight developing concave surface and the inclined developing concave surface is 45°.
[0012] Preferably, the positions of the developing grooves of two adjacent groups of developing grooves are staggered with each other.
[0013] Preferably, several of the developing grooves in each group of developing tanks are circumferentially opened on the outer peripheral surface of the needle tube with the axis of the needle tube as a reference.
[0014] Preferably, the number of the developing grooves in each group of developing grooves is 4 to 6.
[0015] Preferably, a plurality of groups of the developing tanks are arranged at intervals on the outer peripheral surface of the needle tube.
[0016] Preferably, the strong developing portion is arranged in the area from 1 cm to 3 cm from the fixed connection end of the needle tube toward the puncture end of the needle tube.
[0017] Compared with the prior art, the beneficial technical effects of the utility model are:
[0018] (1) The front section of the needle tube has a strong developing portion on its outer circumference, which allows the outer circumference of the needle tube to scatter more sound waves, thereby generating stronger reflection and scattering signals. These signals are converted into images after being received by the receiver of the ultrasonic imaging device, thereby more clearly showing the position and shape of the needle tube, improving the recognition of the needle tube after imaging, and avoiding damage to blood vessels and nerves during blind puncture;
[0019] (2) The groove bottom of the developing groove, i.e., the developing concave surface, is composed of a straight developing concave surface and two inclined developing concave surfaces, so that the complexity of the sound wave reflection surface of the developing concave surface is maximized as much as possible, and the developing groove positions of two adjacent groups of developing grooves are staggered with each other, which is more recognizable and easier to observe by human eyes compared with the existing square developing surfaces or triangular developing surfaces arranged in a regular pattern;
[0020] (3) The angle between the straight developing concave surface and the inclined developing concave surface is 45°. The inclined developing concave surface at this angle has the largest projection area when viewed from above, so the ultrasonic developing effect of the edge of the needle tube is better and the practicability is strong.

The diameter and length of the needle tube can be selected according to the use requirements, so the specific parameter values are not repeated here;
[0028] A strong developing portion 3 is provided on the outer peripheral surface between the fixed connection end 1 and the puncture end 2 of the needle tube, and the strong developing portion 3 is provided in the area of 1 cm to 3 cm from the fixed connection end 1 of the needle tube toward the puncture end 2 of the needle tube, and its specific range is not limited thereto, and its area size can be customized according to the use requirements;
[0029] The strong developing part 3 is a plurality of developing tanks arranged on the outer circumference of the needle tube. The plurality of developing tanks are arranged on the outer circumference of the needle tube at intervals. The number of developing tanks can be selected according to the use requirements, so the specific value is not repeated here.
[0030] Each group of the developing tanks is composed of a plurality of developing grooves, and the bottom surface of the developing groove forms a developing concave surface for enhancing the ultrasonic developing visibility. The shape of the developing concave surface can refer to Figure 4 That is, each of the developing grooves is composed of a straight developing concave surface 4 and two inclined developing concave surfaces 5, the middle parts of the two inclined developing concave surfaces 5 intersect with the middle part of the straight developing concave surface 4, and the two inclined developing concave surfaces 5 are symmetrically arranged on both sides of the straight developing concave surface 4, and the straight developing concave surface 4 and the inclined developing concave surfaces 5 make the bottom surface of the developing groove a symmetrical pattern;
[0031] Moreover, the angle between the straight developing concave surface 4 and the inclined developing concave surface 5 is 45°, and the projected area of the inclined developing concave surface 5 at this angle is the largest when viewed from above, so that the ultrasonic developing effect of the edge of the needle tube is better;
[0032] In addition, the shape of the developing concave surface can also be selected according to the use requirements, such as "X" shape, "M" shape, "cross" shape, etc., but not limited to this. The purpose is to increase the sound wave reflection surface so that the needle tube no longer reflects the sound wave with a single curved surface. The shape, size and specifications of the developing groove can be selected according to the use requirements.
[0033] The positions of the developing grooves of two adjacent groups of developing grooves are staggered with each other, and the design purpose is to increase the complexity of the arrangement of the developing grooves of the strong developing part 3, which helps to enhance the visibility of the needle tube in the ultrasonic developing state to a certain extent, and is convenient for human eye observation;

The number of developing grooves in each group of developing grooves is 4 to 6, and the number can be selected according to the use requirements, so the specific number is not repeated here;
[0035] The strong developing part 3 arranged on the outer peripheral surface of the needle tube makes the outer peripheral surface of the needle tube no longer form a complete circumferential surface;
[0036] It should be noted that the strong developing section 3 can make the outer peripheral surface of the needle tube scatter more sound waves, thereby generating stronger reflection and scattering signals. These signals are converted into images after being received by the receiver of the ultrasonic developing equipment, thereby more clearly displaying the position and shape of the needle tube, improving the recognition of the needle tube after development, avoiding damage to blood vessels, nerves, etc. during blind puncture, and having strong practicality.
