Soft outer sleeve special for endoscope auxiliary instrument

Abstract

The invention relates to a soft outer sleeve special for an endoscope auxiliary instrument. A supporting circular ring A5 and a supporting circular ring B4 are arranged at the front end of a main sleeve 1; a supporting circular ring C6 and a supporting circular ring D7 are arranged at the rear end of the main sleeve 1; and an auxiliary sleeve comprises a biopsy channel I2 and a biopsy channel II3,wherein a sealing cap I9 and a sealing cap II10 are detachably installed on an extension section opening I2-2 and an extension section opening II3-2 respectively. The special outer sleeve in the invention is ultrathin, transparent and sterile, and can protect an endoscope body from being polluted by colouring agents and the like in the using process; and in addition, the sleeve body is soft and rich in toughness, can be bent along with bending of an endoscope, resists traction caused by bending of the endoscope, and is not prone to breakage. Compared with a double-channel endoscope, the special outer sleeve is simple in structure, low in cost and convenient to popularize and use clinically.

Description

technical field [0001] The invention relates to the field of medicine, and belongs to the field of digestive endoscopy, in particular to a special overtube for soft endoscopic auxiliary instruments. Background technique [0002] In recent years, with the development of science and technology and the continuous innovation of medical technology, the clinical application of digestive endoscopy diagnosis and treatment technology and new technology has been widely promoted. However, the development and innovation of diagnosis and treatment technology is inseparable from the support of advanced medical equipment. To successfully complete the minimally invasive treatment of gastrointestinal diseases such as polyps and early cancer, endoscopists not only need to have solid knowledge reserves and skilled technical capabilities, but also need to have a handy endoscope. [0003] At present, a single-channel endoscope is generally used clinically, and the endoscope has only one biopsy ...

AI Technical Summary

Problems solved by technology

In the process of gastrointestinal diagnosis and treatment, this channel can only be inserted into one auxiliary device for operation at a time, but in reality, completing an endoscopic treatment often requires multiple auxiliary devices, which need to be inserted back and forth through this single channel Or pull out the instrument for repeated replacement, sometimes it needs to be pulled out together with the endoscope to achieve the purpose, and then reinserted, which greatly increases the time of endoscopic diagnosis and treatment, increases the risk of auxiliary equipment contamination and the pain of the patient

[0004] In addition, in the process of diagnosis and treatment, a variety of auxiliary instruments are often required to cooperate. For example, if hemostasis is required during the cutting process, the cutting knife needs to be pulled out first, and then inserted into the hemostat to stop the bleeding, which wastes time and increases the risk of bleeding for the patient. Single-channel endoscope is difficult to meet the needs of endoscopists in the process of endoscopic treatment, thus reducing work efficiency and treatment effect; in the process of endoscopic treatment, it is often necessary to use various dyes for staining of lesions Or spray all kinds of hemostatic drugs on the wound surface after treatment, some dyes or hemostatic drugs will adhere to the endoscope mirror body, and the contaminated mirror body is not easy to clean and remove

[0005] In response to the defects of single-channel endoscopes, some manufacturers currently produce dual-channel endoscopes to try to make up for the shortcomings of single-channel endoscopes. However, dual-channel endoscopes are expensive, and the mirror body is thick. It is difficult to tolerate under the condition, and it is not widely used in hospitals, especially small and medium-sized hospitals.
