Problems solved by technology

However, minimally invasive heart surgery only requires 2-3 incisions about 1-3cm in length, and conventional cardiac defibrillation electrodes cannot be placed for defibrillation
At present, there are no in-body defibrillation electrodes for minimally invasive cardiac surgery at home and abroad. Only external defibrillator electrodes can be attached to the chest wall for defibrillation. Intracardiac defibrillation requires only 20J current, but external 200J for defibrillation not only has poor defibrillation effect, but also significantly increases the occurrence of defibrillation complications. Therefore, it is of great clinical significance to develop a new type of defibrillation electrode for in-body minimally invasive cardiac surgery.

Embodiment 1

[0033] like figure 1As shown, an in-body defibrillation electrode includes a base 1, an electrode 2 rotatably connected to the base 1 and a drive block 3 slidingly connected in the base 1, and the in-body defibrillation electrode 2 is connected with the catheter (the The catheter is a commercially available common intracardiac defibrillation catheter. The catheter is used after the part with the electrode 2 at the front end is removed. , used to pull the drive block 3 to slide, the lead 15 in the catheter is connected to the electrode 2, the positioning block 8 has a through hole 16 for the pull rope and the lead 15 to pass through, and the general shape of the base 1 is cylindrical; the base 1 It is composed of two half-open shells. The two shells are separated along the axis direction. After the shells are combined, a cavity is formed. The driving block 3, the positioning block 8 and the electrode 2 are all located in the cavity, and the shells are closed. Afterwards, they ...

Embodiment 2

[0037] like Figure 2-6 As shown, an in-body defibrillation electrode 2 includes a base 1, an electrode 2 rotatably connected to the base 1 and a drive block 3 slidingly connected in the base 1, and the in-body defibrillation electrode 2 is connected with a catheter After use, the stay rope in the catheter passes through the base 1 and the positioning block 8 in sequence and is connected to the driving block 3 for pulling the driving block 3 to slide. The wire 15 in the catheter is connected to the electrode 2, and the middle part of the positioning block 8 There is a through hole 16 for the stay cord to pass through, and there is a through hole 16 for the wire 15 to pass through at the lower position of the positioning block 8. Usually, the shape of the base 1 is cylindrical; the base 1 has two halves. The two shells are separated along the axial direction, and the shells are combined to form a cavity. The driving block 3, the positioning block 8 and the electrode 2 are all l...

Abstract

The invention discloses an in-body type defibrillation electrode and a defibrillator applying the in-body type defibrillation electrode. The integrated defibrillation electrode comprises a base, an electrode rotationally connected to the base and a driving block slidably connected into the base, an opening is formed in the upper end of the base, the electrode is located in the opening, one end of the electrode is rotationally connected into the opening, and the rotationally connected end of the electrode is provided with a driving rod used for driving the electrode to rotate; the driving block is connected with the driving rod; and a reset mechanism for resetting the driving block is arranged in the base. The defibrillator comprises a host, a defibrillation catheter and the in-body type defibrillation electrode; and the in-body type defibrillation electrode is fixed at the front end of the defibrillation catheter, and the rear end of the defibrillation catheter is connected with the host. Compared with the prior art, due to the fact that the electrode directly enters the thoracic cavity through the catheter during use and can be directly attached to the outer wall of the heart, operation is easy and convenient, blood vessels do not need to be punctured, bleeding spots are few, corresponding complications are few, current can directly act on the heart, and power consumption is relatively low.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and equipment, and in particular relates to an in-body defibrillation electrode which is used for defibrillating the heart by extending into the human body during operation. Background technique [0002] Defibrillation is the process of terminating ventricular fibrillation using medical devices or specific drugs. In medicine, the term "defibrillation" usually refers to the use of a defibrillator to stop atrial fibrillation by sending an electrical discharge to the heart. Defibrillation can be divided into three categories according to different methods: 1. Electrical defibrillation - defibrillation by defibrillator discharge; 2. Drug defibrillation - defibrillation by injecting drugs to affect the electrical activity of the heart; 3. Manual defibrillation - defibrillation Precordial percussion. The most commonly used and most effective method is electrical defibrillation, which treat...
