Description

A puncture needle for cardiovascular interventional therapy

technical field

The utility model relates to the technical field of medical devices, in particular to a puncture needle for cardiovascular interventional therapy.

Background technique

Interventional therapy is an emerging treatment method between surgery and medical treatment, including endovascular interventional and non-vascular interventional therapy. Now it has been called the three pillar disciplines together with surgery and internal medicine. Simply put, interventional therapy means no surgery. In the case of exposing the lesion, it is a minimally invasive treatment method to treat the local lesion under the guidance of imaging equipment by making tiny channels with a diameter of several millimeters on the blood vessels and skin, or through the original pipeline of the human body.

However, the existing puncture needles for cardiovascular interventional therapy still have some shortcomings. First, the existing puncture needles for cardiovascular interventional therapy usually use a disposable syringe to pierce the blood vessel, and then the needle tube is pulled out from the puncture needle, and the guide wire is inserted into the blood vessel. The puncture needle is sent into the blood vessel. When the guide wire is inserted, a large amount of blood will flow out of the puncture needle, which will pollute the working surface. Secondly, the existing puncture needle for cardiovascular interventional therapy is prone to deviation during the puncture process, aggravating the pain of the patient.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-4, the present utility model provides a technical solution: a puncture needle for cardiovascular interventional therapy, comprising a puncture needle body 1, a needle tube 2, a rubber plug 3, a push rod 4, a push handle 5, a rubber plug 3, The center of the push rod 4 and the push handle 5 is provided with a guide wire hole 6 with the same diameter, and the connecting end of the needle tube 2 is provided with a one-way valve 8 to prevent blood from flowing into the needle tube 2 from the gap between the needle hole and the guide wire. The outside of the needle body 1 is provided with a splash-proof cover 9 , a medicine storage box 10 is fixedly installed inside the splash-proof cover 9 , and a hemostatic agent 11 is stored in the medicine storage box 10 , which can effectively stop the bleeding of the wound. A hemostatic cotton 12 is arranged outside the medicine storage box 10, a spray pipe 13 is arranged on the side of the medicine storage box 10 close to the needle tip, and an air inlet 14 is opened on the inner surface wall of the top of the medicine storage box 10. 14 is connected with a pressurized air bag 16 through the air intake pipe 15, and a pressure difference is generated inside and outside the air hole 14 through the pressurized air bag 16, the spray pipe 13 is communicated with the air intake pipe 15, and the top of the medicine storage box 10 is located at the air intake hole 14. A shaped blocking ball 17 prevents the hemostatic agent 11 in the medicine storage box 10 from flowing out through the air hole 14 .

Specifically, as shown in FIG. 1 , a trapezoidal guide hole 7 is formed on the side wall of the needle tube 2 close to the puncture needle body 1 , so that the guide wire can enter the needle hole of the puncture needle body 1 more quickly and accurately.

Specifically, as shown in FIG. 1 , a sealing film 19 is provided inside the needle hole of the puncture needle body 1 near the needle tip. The sealing film 19 is a polytetrafluoroethylene elastic film with a thickness of 0.5 mm to prevent the puncture needle body 1 from entering the blood vessel Then, the blood flows into the needle tube 2 through the needle hole.

Specifically, as shown in FIG. 1 , the outside of the needle tube 2 is covered with a non-slip sleeve 20 to prevent slippage during the operation of the push rod 4 .

Specifically, as shown in FIG. 1 , the puncture needle body 1 is provided with an elastic band 21 at the connection near the needle tube 2 , and the puncture needle body 1 is fixed by the elastic band 21 .
