Description

Drainage tube for ultrasound

Technical Field

The application relates to the technical field of medical instruments, in particular to a drainage tube for ultrasound.

Background

The pancreatic pseudocyst is located in the retroperitoneum and is deep in position, so that surgical operation treatment is frequently adopted, the wound is large, and the cost is high. The ultrasonic endoscope guided pseudocyst drainage of pancreas gradually replaces surgical operation at present due to the minimally invasive and simple operation, and becomes the first choice treatment mode for the pathological changes. In addition, for other deep benign cysts such as subphragmatic abscess, pelvic abscess and the like, the conventional treatment method is percutaneous external drainage, and the internal drainage guided by the ultrasonic endoscope also has unique advantages for the lesions, such as short drainage path due to close proximity to the lesion; drainage liquid is discharged through the body cavity, and the life of a patient is not obviously influenced, so that the life quality is relatively high, and the conventional external drainage treatment is replaced to a certain extent.

The internal drainage guided by the ultrasonic endoscope can adopt a metal bracket or a plastic bracket. Compared with metal stents, plastic stents are widely applied to the treatment of biliary tract diseases and pancreatic diseases due to the advantages of low price and convenient placement. However, the currently clinically used internal drainage plastic stent is designed for performing duodenoscope treatment under X-rays, the external coating is made of an X-ray opaque material, and the X-ray radiographic development is good, but in an ultrasonic field, the drainage tube has a smooth tube wall, acoustic impedance is close to human tissues, the drainage tube placed in a body is often blurred in an ultrasonic image, and the drainage tube can only display part of the tube wall and cannot display a complete picture, so that accurate positioning is difficult. Therefore, when performing endodrainage treatment guided by ultrasonic endoscope, the operation must be completed by means of X-ray imaging at the same time, namely, the hospital department with two devices in the same medical treatment room must be used for carrying out the relevant treatment. However, both of these devices are relatively expensive, and only one of them is available in many hospitals or departments, and both of them are bulky and inconvenient to move. In addition, for some patients, such as pregnant women and children, the patients are at risk of teratogenesis after being exposed to X-rays for a long time, so that the development and popularization of the drainage technology in the ultrasonic endoscope are limited.
