Self-telescopic in-esophagus support

Abstract

The invention relates to a self-telescopic in-esophagus support, which comprises a jacking ring, a force transmission plate, a support body and a film sleeve which is sleeved outside the support body. The jacking ring is arranged on one end of the support body and is connected with the film sleeve through a connecting wire, the force transmission plate is arranged on the jacking ring through a sleeve ring in a penetrating way, the support body comprises a plurality of telescopic units which are vertically arranged, each telescopic unit consists of two clamping arms and multiple pairs of clamping rings, the two clamping arms are of an X shape after mutual hinging, two ends of each clamping arm are respectively provided with hinging holes, two clamping arm ends on the same side of two adjacent telescopic units in the vertical direction are respectively hinged together, and the lower end of the force transmission plate is erected on the clamping ring of the telescopic unit on the foremost top end. The self-telescopic in-esophagus support is arranged in the esophagus canceration position of a patient, the narrow section of the esophagus can be effectively enlarged during taking food, the support is closed in a non-food state, the backflow of contents in the stomach can be effectively stopped, the feeling of a foreign object in the non-food state of the patient is obviously alleviated, and pains on taking food of the patient are relieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a self-shrinking esophageal stent. Background technique [0002] At present, cancer is one of the three major killers of human diseases, and the mortality rate of patients is relatively high. However, after decades of careful research by people in the medical and health circles, therapeutic drugs continue to appear, and medical methods are also continuously improved, such as the treatment of cancer caused by malignant tumors. For esophageal stenosis, clinicians put in stents to achieve the purpose of expanding the pipeline. Taking esophageal cancer as an example, esophageal cancer is one of the common malignant tumors of the digestive tract in China, ranking sixth among malignant tumors in the world. Once discovered, it is mostly in the middle and late stage , The most common problem in patients with middle and advanced esophageal cancer is the difficulty in swallowing and eating c...

Problems solved by technology

[0002] At present, cancer is one of the three major killers of human diseases, and the mortality rate of patients is relatively high. With the emergence of esophageal cancer, medical methods are also continuously improved. For example, in the treatment of esophageal stenosis caused by malignant tumors, clinicians put in stents to achieve the purpose of expanding the pipeline. Taking esophageal cancer as an example, esophageal cancer is one of the common malignant tumors of the digestive tract in China. It ranks 6th among malignant tumors in the world. Once discovered, most of them are in the middle and late stages. The most common problems in the middle and late stages of esophageal cancer patients are the difficulty in swallowing and eating caused by esophageal stenosis and obstruction in different degrees, which obviously affects the quality of life of patients.

Although the placement of the existing esophageal stent can quickly relieve the patient's difficulty in swallowing and eating, after the existing stent is placed, the stent always tightly supports the esophagus no matter when eating or not, and the patient's foreign body sensation is obvious. Gastric reflux is a major disadvantage, which obviously limits the clinical application of esophageal stents, making it difficult for most patients with esophageal cancer to receive stents.
