Problems solved by technology

[0003] At present, there are three ways to deliver therapeutic drugs such as stem cells or growth factors to the myocardial infarction area: one is to deliver stem cells to the coronary arteries and veins in the myocardial infarction area through a catheter, and the usage rate of stem cells in this method is relatively low. According to literature reports, only 5% of stem cells can work in the myocardial infarction area; the second is to inject stem cells into the damaged myocardium through the epicardium through thoracotomy, but the trauma is relatively large, which is not conducive to the patient's physical recovery The third is to use the method of interventional cardiology to puncture the sheath equipped with the injection needle through the femoral artery and deliver it to the left ventricle of the heart, and inject the stem cells into the damaged myocardium through the endocardium, but the most important The problem is that the positioning treatment of the target area is not accurate, and the existing technology is not ideal in the technical link of accurately delivering the drug to the target area.

Embodiment Construction

[0026] The injection system of the present invention can accurately inject medicine into the target area in the body. The present invention will be further described below through the examples and drawings, but the present invention is not limited to the scope of the examples.

[0027] For the convenience of description herein, the "distal end" described in the injection system of the present invention refers to the end near the injection needle, i.e. the injection end; and the "near end" refers to the end away from the injection needle.

[0028] Embodiment 1 of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 As shown, the injection system of the present invention can install detection electrodes on the far end of the existing injection system or device, and can install a head electrode 2 at the far end of the injection device, and can use a cylindrical metal potential electrode. A plurality of metal ring-shaped elec...

Abstract

The invention discloses an injection system. The injection system comprises an injection device and an electric signal detection device. The injection system is characterized in that the electric signal detection device comprises at least one electrode; and the electrode is arranged at the injection end of the injection device. The injection system can accurately position a target injection region so as to accurately inject medicine to a target region of the inner wall of a body cavity. The injection device can be better realized by mounting a bending compensation mechanism for the length of an injection needle, an injection needle locking mechanism, a quantitative automatic injection mechanism and the like.

Description

technical field [0001] The invention relates to the field of interventional treatment instruments, in particular to an injection system for injecting medicine in the body. Background technique [0002] In the field of interventional therapy, using a suitable injection system or device to accurately position and inject drugs into the target area is the key to treatment. For example, the use of biochemical agents such as hepatocyte growth factor or stem cells to treat the infarcted myocardial region after myocardial infarction is a hot spot in current biomedical research. How to accurately position and inject the above drugs into the myocardial infarction region is the key to this technology. [0003] At present, there are three ways to deliver therapeutic drugs such as stem cells or growth factors to the myocardial infarction area: one is to deliver stem cells to the coronary arteries and veins in the myocardial infarction area through a catheter, and the usage rate of stem c...
