Description of the embodiments
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, 2 and 4, the ultrasonic guiding disposable puncture needle of the present invention comprises a middle needle seat 1, a middle needle 3, a depth positioning buoy 2 and a sheath 4, wherein one end of the middle needle seat 1 is connected with the middle needle 3 through the depth positioning buoy 2, the sheath 4 is sleeved outside the middle needle 3, the other end of the middle needle seat 1 is provided with an inner needle 6 or a connecting extension tube component, the inner needle 6 is fixed on the inner needle seat 5, the inner needle 6 is inserted into the middle needle 3 through the middle needle seat 1, a plurality of pits 7 are formed at the needle tip of the middle needle 3 or the inner needle 6, the pits 7 form a reflection matrix to enhance ultrasonic reflection, the deep puncture echo is louder, the needle tip is clearly visible, and the positioning is easy.
The shape of the pit 7 is circular as shown in fig. 3, the shape of the pit 7 is triangular as shown in fig. 6, and the shape of the pit 7 is spiral as shown in fig. 7. As shown in fig. 8, the shape of the pit 7 may be a heart shape or the like.
As shown in fig. 5, when the puncture is positioned under the guidance of ultrasound, the probe receives complete parallel echoes at any angle and depth to form a clear ultrasound image, and a satisfactory image effect is obtained. If the surface of the needle body is smooth, the probe cannot or slightly receive echoes, and therefore a clear and accurate developing effect cannot or is difficult to obtain.
In the process of puncturing by a patient, the inner needle is inserted into the middle needle for use, after puncturing is finished, the inner needle is pulled out, if the inner needle is not available, the blood can be sprayed out by erroneously penetrating into a blood vessel, and the inner needle can block the blood without liquid.
