Example

[0031] (Example 1)

[0032] see Figure 1 to Figure 4 The puncture device of this embodiment includes a puncture needle 1 for puncturing the human body and forming a puncture channel in the body, a puncture needle core 2 used for puncturing the human body in the puncture needle 1 The needle tube of the puncture needle 1 is sent into the human body and is left in the puncture channel after the puncture needle 1 is pulled out. The guide wire 3 used as a guide for the next puncture and is used to remove the puncture needle 1 from the human body. A sterile dressing 4 covered and fixed by the exposed part of the guide wire 3.

[0033] The puncture needle 1 is a commonly used No. 9 lumbar puncture needle (the outer diameter of the needle tube is 0.9mm), and the tip of the front part of the needle tube of the puncture needle 1 is a spoon-shaped bevel. The tip of the front part of the puncture needle core 2 is a spoon-shaped slope. Guide wire 3 is a medical guide wire with a slightly cur...

Example

[0037] (Example 2)

[0038] see Figure 1 to Figure 5 The rest of the puncture device of this embodiment is the same as that of embodiment 1, except that: puncture needle 1 is a commonly used No. 7 lumbar puncture needle in clinical practice (the outer diameter of the needle tube is 0.7mm, which is mainly used for patients with high intracranial pressure Or pediatric patients). The puncture device also includes a spacer 5 arranged between the exposed part of the guide wire 3 and the surface of the human body after the puncture needle 1 is pulled out of the human body. The gasket 5 is a medical cotton pad, and the gasket 5 is provided with a notch 51. When in use, the bottom of the exposed part of the guide wire 3 is clamped and fixed in the notch 51.

[0039] see Image 6 and Figure 7 When using the puncture instrument of this embodiment for lumbar puncture, the rest of the steps are the same as in embodiment 1, except that: step ④ is to keep the guide wire 3 still, pull out the...

Abstract

The invention relates to a puncture instrument, which comprises a puncture needle and a guide wire, wherein the puncture needle is used for realizing puncture on a human body and forms a puncture passage in the body, and the guide wire is suitable for being fed into the human body along a needle tube of the the puncture needle and is remained in the puncture passage to be used as a guide element for next puncture after the puncture needle is pulled out. A use method of the puncture instrument comprises the following steps that a puncture needle core is arranged in the puncture needle to form a whole, and is used for carrying out puncture on a patient; after the puncture to the proper position, the puncture needle core is pulled out for drainage; after the drainage is completed, the front part of the guide wire is fed into the human body along with the tail end of the needle tube of the puncture needle; when the puncture needle is pulled out, aseptic dressing is used for covering the guide wire and fixing the guide wire onto the body surface of the human body; during the puncture in a next time, the puncture needle reaches the puncture position along the guide wire. The puncture instrument provided by the invention is applicable to the patient requiring several times of puncture, and the one-step success of the subsequent puncture is ensured in the use process; the body injury and the psychological burden caused by multi-time puncture on the patient are avoided; the occurrence of complications such as headache and backache is greatly reduced.

Description

[0001] This application is a divisional application. The filing date of the original application was May 3, 2012, the application number was 201210134280.6, and the title of the invention was puncture equipment and its use method. Technical field [0002] The invention relates to a medical puncture instrument and a method of using the instrument. Background technique [0003] Puncture is an effective means of clinical diagnosis and treatment, including lumbar puncture, pleural puncture, abdominal puncture, etc. Lumbar puncture is a commonly used diagnosis and treatment technique in neurology and surgery. It uses a lumbar puncture needle to puncture the subarachnoid space of the lumbar spinal cord. In the middle of the lower back, use a cored lumbar puncture needle to pierce about 5cm, puncture the dura mater, pull out the needle core, and the cerebrospinal fluid is removed from the hollow puncture needle Drain it out. It can be used to measure intracranial pressure, reduce intr...
