Puncture instrument and use method thereof

Abstract

The invention relates to a puncture instrument and a use method thereof. The puncture instrument comprises a puncture needle and a guide wire, wherein the puncture needle is used for puncturing a human body and forms a puncture channel in the body; and the guide wire is put into the human body along a needle tube of the puncture needle and is left in the puncture channel to be used as a guide part after the puncture needle is pulled out. The use method of the puncture instrument comprises the following steps: placing a puncture needle core into the puncture needle to form an integrated structure to puncture a patient; pulling out of the puncture needle core after puncturing in place, and draining; placing the front end of the guide wire into the human body along the tail end of the needle tube of the puncture needle after drainage is finished; pulling out of the puncture needle; leading the guide wire to be covered and fixed on the body surface of the human body by utilizing a aseptic dressing; and then puncturing again, so that the puncture needle achieves the puncture part along the guide wire. The puncture instrument is suitable for patients need multiple times of paracentesis; with adoption of the puncture instrument, one-time success of follow-up puncture can be ensured when the puncture instrument is used; body injuries and psychological burdens caused by multiple times of puncturing patients can be avoided; and the occurrences of complications such as headache and backache and the like can be greatly reduced.

Description

technical field [0001] The invention relates to a medical puncture instrument and a method for using the instrument. Background technique [0002] Puncture is an effective means of clinical diagnosis and clinical treatment, including lumbar puncture, thoracentesis, paracentesis and so on. Among them, 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 back, a lumbar puncture needle with a core is used to penetrate about 5cm, puncture the dura mater, pull out the needle core, and the cerebrospinal fluid flows from the hollow puncture needle. Drain out. It can be used to measure intracranial pressure, reduce intracranial pressure, drain bloody or inflammatory cerebrospinal fluid, perform irrigation therapy, and inject drugs. However, the puncture may puncture the nerve or vascular plexus, causing nerve damage or hemor...

AI Technical Summary

Problems solved by technology

2. After the indwelling drainage system restricts the patient's activities, it is not conducive to treatment, because patients with severe craniocerebral disease need to turn over frequently, pat their backs or carry for inspection

3. The drainage tube may be accidentally pulled out, resulting in drainage failure

4. Improper maintenance of the drainage system may cause retrograde infection

5. Due to the continuous opening of the subarachnoid space of the lumbar spinal cord, when the patient has a sudden attack of intracranial hypertension, it may cause brain herniation

6. If the operation of puncture and tube placement is improper, the drainage tube may be cut off by the puncture needle, and the broken end will remain in the body

7. Expensive
