A portable magnetic induction positioning guide device and method thereof

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a portable magnetic induction positioning guide device and method. The device comprises a cavity magnetic induction diagnosis and treatment catheter used for being conveyed into the human cavity, a tiny magnet which is arranged on the head of the cavity magnetic induction diagnosis and treatment catheter andused for transmitting magnetic signals and a catheter tracker which is located on the body surface and used for detecting the magnetic signals which are transmitted by the tiny magnet. According to the portable magnetic induction positioning guide device, the cavity magnetic induction diagnosis and treatment catheter extends into the human cavity, the tiny magnet in the head of the cavity magneticinduction diagnosis and treatment catheter transmits the magnetic signals, the catheter tracker which is located on the human body surface senses the magnetic signals, and accordingly poisoning and guiding operation is conducted; the portable magnetic induction positioning guide device is convenient to operate, accurate in positioning and guide, free of X-ray radiation and wide in suitable crowdrange.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a portable magnetic induction positioning guide device and a method thereof. Background technique [0002] In the medical field, acute spontaneous hemorrhage or hemorrhage during operation is a common clinical emergency. Its condition is critical and can lead to hemorrhagic shock and life-threatening at any time, such as hemoptysis, hematemesis, hematochezia, hematuria, obstetric hemorrhage, intraoperative and surgical Posterior hemorrhage, traumatic hemorrhage, etc.; the use of arterial or aortic balloon blood flow occlusion or occlusion can immediately and effectively block the blood flow and completely stop the bleeding, which is the most timely and effective life-saving measure. Balloon occlusion or occlusion refers to the percutaneous puncture of peripheral blood vessels (femoral artery, brachial artery, etc.) The balloon catheter is used to block the blood flow by inflatin...

AI Technical Summary

Problems solved by technology

[0003] Existing arterial or aortic dilatation balloon catheters block blood flow, and the operation must be completed under the guidance of extracorporeal X-ray real-time fluoroscopy images (Digital Subtraction Angiography-DSA), which have precise real-time anatomical positioning Function, it can monitor the operation and operation of the balloon catheter in the human cavity in a panoramic and real-time manner, and is widely used clinically, but the operation under the guidance of X-ray real-time fluoroscopy digital image (DSA) requires expensive DSA equipment and a special interventional operating room , or high-standard clean (thousand-grade) hybrid operating rooms, which are difficult to have in most secondary and tertiary hospitals at home and abroad; however, acute spontaneous bleeding and surgical bleeding not only occur in hospitals, This kind of place is convenient for immediate rescue, and more and more common spontaneous massive bleeding occurs without warning in non-medical places and in daily life situations, such as communities, families, stations, squares, roads, travel, etc. It occurs suddenly in daily life scenes such as the ground, and immediate measures need to be taken, such as arterial or aortic balloon dilatation to block blood flow treatment, in the feeding artery of the bleeding viscera, the aorta in the opening area of ​​the feeding artery, or the aorta near the heart Block the blood flow to achieve the therapeutic effect of immediate hemostasis

Almost all ambulances do not have DSA equipment, and it is difficult to guide the process of percutaneous percutaneous puncture of the balloon catheter into the target site in real time, and it is impossible to timely and accurately perform arterial or aortic balloon dilation to block blood flow

In many cases of first aid in the field and sudden natural disasters, the rescue site does not even have a basic power supply, and it is impossible to install DSA imaging guidance equipment; in addition, even in hospitals, there are still some patients, such as Pregnant women, young children, etc., due to radiation safety considerations, are not suitable for DSA-guided balloon catheterization methods, for example, intubation of X-ray sensitive people or sensitive organ parts, infants, children, pregnant women, pregnant women, gonads body (male testis, female ovary), high-functioning glands (adrenal gland, thymus, thyroid gland, pituitary gland, etc.), interventional radiology operations such as catheterization and other X-ray imaging monitoring will receive a certain dose of X-ray radiation, and Such people and special parts are subject to a certain dose of X-ray radiation, which may cause permanent physical harm, so it is not possible to use external X-ray real-time fluoroscopy images for operations
