Description

Technical Field

[0001] The utility model relates to the technical field of interventional therapy, in particular to an interventional therapy puncture needle. Background Art

[0002] Interventional therapy is an emerging treatment method between surgical and internal medicine treatment, including intravascular intervention and non-vascular interventional therapy. After more than 30 years of development, it is now called one of the three pillar disciplines together with surgery and internal medicine. Simply put, interventional therapy is a minimally invasive treatment method that treats local lesions under the guidance of imaging equipment (angiography, fluoroscopy, CT, MR, B-ultrasound) by making tiny channels with a diameter of several millimeters in the blood vessels or skin without exposing the lesions through surgery, or through the original channels of the human body. Oncology drugs need to be delivered to the patient's body through interventional puncture needles, which is beneficial to the treatment of patients.

[0003] A puncture needle is a medical device used for tissue sampling and injection treatment of various organs such as the kidneys, liver, lungs, breast, thyroid, prostate, pancreas, testicles, uterus, ovaries, and body surface during minimally invasive surgery.

[0004] The Chinese patent document with application number 202320616295.X discloses a drug interventional treatment device: a three-way seat with a three-way cavity inside is detachably connected to the interventional puncture needle system through the cannula end, and side branch tube systems are connected on both sides of the three-way seat respectively. The side branch tube systems are used to connect the drainage bag and the syringe respectively. When the drug is introduced into the lesion, the conduction direction of the three-way cavity can be adjusted by adjusting the rotary valve on the three-way seat, and the cavity on one side of the drainage bag can be connected.

[0005] However, when in use, the device cannot filter and clean larger blood clots and other extracts, which can easily cause blockage of the drainage tube when the blood clots and other extracts enter the drainage tube. At the same time, the blood clots and other extracts are also likely to remain inside the three-way seat, which can easily drive the residue into the patient's affected area when the medicine is pushed in. Utility Model Content
