Problems solved by technology

However, due to the structure of the existing puncture needle, most doctors will encounter the following troubles during the operation: the guide wire will follow up after the puncture is successful, and it is found after angiography that the deep femoral artery has entered, so it needs to be punctured again, and even causes Failed operation, increased pain for patients

Embodiment Construction

[0011] see figure 1 . The structure of this femoral artery antegrade puncture needle consists of an integral cylindrical needle body and a needle handle. There is a partition wall 30 in the channel of the needle body and the needle handle, and the partition wall 30 axially divides the channel into two independent left channel 14 and right channel 24 . The port of the left channel 14 is the outlet 13 of the oblique left imaging channel. There is a left imaging channel 12 and its left imaging channel inlet 121 at the needle handle of the left channel 14. In practice, a heparin cap is arranged on the left imaging channel inlet 121 (not shown in the figure), the heparin cap is screwed with the left contrast channel inlet 121 bolt. The port of the right channel 24 is the outlet 23 of the right imaging channel, and the outlet 23 of the right imaging channel is arranged opposite to the outlet 13 of the left imaging channel, and the positions are divided into front and rear, that is...

Abstract

The invention discloses a femoral artery direct puncture needle, comprising an integrated cylindrical needle body and needle handle, a separation wall is arranged in the inner channel, the inner channel is axially divided into a left channel and a right channel which are independent, the port of the left channel is an inclined left contrast channel outlet, a left contrast channel is arranged at the needle handle part of the left channel, the port of the right channel is a right contrast channel outlet which is in backward direction with the left contrast channel outlet, a right contrast channel is arranged at the needle handle part of the right channel, the left channel and the right channel are provided with an unidirectional haemostasis valve respectively, the ports of the right contrast channel and the left contrast channel are respectively provided with a heparin cap. When the puncture needle is used for the intervention treatment, even though the puncture needle enters the femoral artery, the seal wire is ensured to enter the target blood vessel, the invention solves the problem that the puncture is done again because the seal wire enters the femoral artery after radiography, even the operation is failure and the patient feels the pain.

Description

【Technical field】 [0001] The invention belongs to the technical field of medical devices, and in particular relates to a femoral artery puncture needle. 【Background technique】 [0002] In the interventional treatment of arteriosclerotic occlusion of the lower extremities, superselection after puncture of the common femoral artery and access to the superficial femoral artery is one of the keys to the operation. However, due to the structure of the existing puncture needle, most doctors will encounter the following troubles during the operation: after the puncture is successful, the guide wire will follow up, and after angiography, it is found that the deep femoral artery has entered, so it is necessary to puncture again, and even cause The operation failed, increasing the pain to the patient. 【Content of invention】 [0003] In order to solve the above-mentioned problems in the prior art, the present invention aims to provide a femoral artery antegrade puncture needle, whic...
