Problems solved by technology

The electrolysis method is usually successful, but a circuit is formed between the positive electrode and the negative electrode through the human body, and the resistance between the two is too large, so the release time is long, and due to individual differences in patients, the release time of different patients varies. In addition, Inserting metal needles under the skin also causes additional trauma to the patient

Abstract

The invention provides a pushing rod, a releasing device and a medical device. The pushing rod comprises a first electric conductor and a second electric conductor. Wherein the first conductor is provided with an inner cavity extending along the axial direction in a penetrating manner and comprises a conductive tube and a conductive spring, and the near end of the conductive spring is electrically connected with the far end of the conductive tube; the second electric conductor is at least partially arranged in the inner cavity in a penetrating mode and is connected with the first electric conductor in a non-electric mode, and a releasing area is arranged at the far end of the second electric conductor. The push rod can be quickly subjected to electrolytic disengagement and has good push performance.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a push rod, a release device and a medical device. Background technique [0002] With the development of medical technology, endovascular interventional therapy has gradually emerged, and has attracted people's attention and attention because of its advantages of less trauma, less risk, and fewer complications. [0003] The principle of endovascular interventional therapy is to build a delivery channel through the human blood vessel path, then push the device to deliver the medical implant to the lesion, and finally release the medical implant to the lesion for treatment. Therefore, the connection between the pushing device and the medical implant is very important. It must not only maintain the effective connection between the medical implant and the pushing device during the delivery process, but also be able to release the medical implant smoothly after it reaches the ...
