Magnetic composite treatment device

Abstract

The invention discloses a magnetic composite treatment device, and belongs to the technical field of medical apparatuses. The magnetic composite treatment device comprises a central pipe, an elastic saccule and a solid magnet. When the magnetic composite treatment device is used, the saccule is placed to an assigned position, after a liquid magnet is injected to the saccule, magnetic attraction isproduced between a solid magnet and the liquid magnet to produce a continuous squeezing force on the solid magnet and the liquid magnet, so that scar tissue is subjected to ischemia and necrosis andfalls, and the magnetic composite treatment device disclosed by the invention can be used for treating upper gastrointestinal stenosis or performing gastric fistula. The magnetic composite treatment device can be completely operated under an endoscope, so that a real minimally invasive surgery is realized; and compared with other treatment means, the magnetic composite treatment device is precisein effects, can reduce the pain of a patient, and during treatment, liquid foods or nutrient substances can be injected through a central channel, so that the nutrient supply of the patient is guaranteed. The magnetic composite treatment device is simple in structure, convenient to use and operate, safe and effective.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a magnetic composite treatment device. Background technique [0002] The upper gastrointestinal tract includes esophagus, stomach, duodenum, etc. Upper gastrointestinal stenosis refers to the stenosis caused by benign and malignant lesions and surgical scars, which often leads to complete or incomplete upper gastrointestinal obstruction, and patients have different degrees of dysphagia , causing ingestion, digestion, absorption disorders, malnutrition, water and electrolyte disorders, weight loss, cachexia, and even death. [0003] With the continuous advancement of medical technology, although the incidence of upper gastrointestinal stenosis has decreased, its incidence is still high, and the treatment methods have not improved significantly. The current treatment methods mainly include surgery, endoscopic esophageal balloon dilatation, endoscopic esophage...

AI Technical Summary

Problems solved by technology

Surgical trauma, high cost, and poor repeatability cause mental and economic losses to patients, are not easy for patients to accept, and have a high chance of restenosis after surgery; the balloon in gastroscopic esophageal balloon dilatation will slide up and down, making it difficult to place At the anastomosis, it is necessary to adjust the position from time to time and prolong the operation time, which will cause the patient to suffer more pain, and the scar itself cannot be removed, and the stenosis may be repeated; the cost of esophageal stent placement through gastroscope is high, and the second is to expand the stenosis After placing the stent, the stent may slip off. The third is that the patient feels a strong foreign body after the stent is placed, and often cannot tolerate it.

[0005] Magnetic compression digestive tract stenosis dredging technology is a new technology that has emerged in recent years. It has been applied to children with esophageal atresia and stenosis. The solid magnet achieves the anastomosis, and gastrostomy is required during the operation. After the stenosis is relieved, the stoma is surgically sutured. The surgical trauma is relatively large, which brings great pain to the patient.

Gastroenterostomy is a common operation in clinical surgery. At present, gastroenterostomy tubes are placed through open gastroenterostomy and endoscopic gastrostomy in medicine, but the surgical trauma is large, and the effect of current gastroenterostomy tubes is not accurate. The low success rate of the operation and the high risk of postoperative intestinal fistula also limit the promotion and popularization of this technology to a certain extent
