Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic puncture needle which can clearly display ultrasonic images. Background Art
[0002] Currently, the surface of puncture needles on the market is mostly smooth, and the ultrasound projected on their surface is mirror-reflected, forming a small number of sound beams, and the angle formed with the insertion direction of the puncture needle is relatively small. As a result, the puncture needle is not clearly displayed in the ultrasound image, and the target nerve cannot be accurately observed. The target position needs to be determined repeatedly, and the puncture accuracy is low.
[0003] In order to increase the reflection of ultrasonic waves, existing puncture needles are designed with ultrasonic texture reinforcement surfaces at the top of the needle body or a certain specific position. Such texture reinforcement surfaces are generally designed to be grooved structures. However, the weak points caused by such structures may cause potential damage to the overall structure of the puncture positioning needle, affecting the hardness and bending resistance of the needle body, thereby increasing the risk of breakage during surgery.
[0004] In addition, in order to prevent the puncture needle from entering too deeply into the soft tissue, a limit ring is provided in the structure of the existing puncture needle. However, this final limit method cannot achieve the control of different depths during the puncture process. The operator only relies on operating experience to grasp the depth of the puncture process, which is not intuitive enough. Utility Model Content
[0005] In order to solve the above problems, the utility model provides an ultrasonic puncture needle which can clearly display ultrasonic images.
[0006] The utility model is realized by the following technical solutions:
[0007] An ultrasonic puncture needle capable of clearly displaying ultrasonic images comprises a needle seat, the lower end of the needle seat being fixedly connected to a needle body, the needle body comprising an inner needle body and an outer needle body which are sleeved together, the outer needle body being sleeved on the surface of the inner needle body, a plurality of grooves being provided on the side of the outer wall of the inner needle body, the outer ring of the groove being sleeved with a platinum-iridium alloy developing ring, and the platinum-iridium alloy developing rings being distributed at intervals on the outer ring of the groove.
[0008] The groove is a hemispherical groove.
[0009] The outer side of the upper part of the outer needle body is connected with a limiting ring.
[0010] The outer surface of the outer needle body is provided with a scale.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The needle body in the structure of the utility model is composed of an inner needle body and an outer needle body. The grooves on the surface of the inner needle body can increase the reflection of ultrasonic waves, which is convenient for clear display in ultrasonic images. At the same time, the structural design of the outer needle body increases the overall strength of the needle body, avoiding the risk of deformation and bending of the needle body at the groove during the puncture process.
[0013] The utility model arranges a platinum-iridium alloy developing ring in the needle body, increases the local ultrasonic reflection intensity of the puncture needle, utilizes the position of the developing ring to assist in judging the depth of the puncture needle, and more intuitively grasps the puncture depth.
