Embodiment 1

[0048] This embodiment provides a visualized puncture device, including:

[0049] The needle tube 100 and the needle 200 at the front end of the needle tube 100;

[0050] The surface of the end of the needle tube 100 close to the needle 200 is provided with a tube body developing area 110;

[0051] The outer surface of the needle head 200 is provided with a needle tip developing area 210;

[0052] Both the tube body developing area 110 and the needle tip developing area 210 can reflect ultrasonic waves.

[0053] The technical effect that the above-mentioned visual puncturing device can achieve is:

[0054] In the process of puncturing the patient, ultrasound can be used to image the tube body developing area 110 and the needle tip developing area 210, so the position of the needle tip can be effectively identified, and the medical staff can perform more accurate puncture operations according to the displayed needle tip position, thereby reducing the number of nerves. Tissue d...

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a visual puncture device. By the aid of the visual puncture device, the problem of vulnerability ofinjury of tissues of nerves, blood vessels and the like due to inaccurate development locations of puncture needles in the prior art can be solved. The visual puncture device comprises a needle tube and a needle head. The needle head is positioned at the front end of the needle tube; a tube body development zone is arranged on the surface of the end, which is close to the needle head, of the needle tube; a needle point development zone is arranged on the outer surface of the needle head; ultrasonic waves can be reflected by the tube body development zone and the needle point development zone.According to the technical scheme, the visual puncture device has the advantages that needle point locations can be effectively discriminated, accurate puncture operation can be carried out by medicalstaffs according to the displayed needle point locations, and accordingly the problems such as injury of the tissues of the nerves, the blood vessels and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a visual puncture device. Background technique [0002] Ultrasound-guided technology is not only suitable for precise block anesthesia of the patient's peripheral nerves, but also during traditional epidural anesthesia and subarachnoid anesthesia (spinal anesthesia), ultrasonic detection technology can also be used to accurately see the patient. The shape of the spinal canal, especially in patients with puerperae or congenital spinal stenosis, the position of the spinal canal determined by the traditional bone palpation method may not be in the same plane due to the special physiological cycle of the parturient, resulting in incorrect position judgment and the position of the puncture needle. Inability to reach the epidural space or displacement, resulting in poor or no anesthesia. [0003] Principle of ultrasonic reflection: The principle of ultrasonic imaging is th...
